Add optional proxy field to InteractiveMode so connect mode can reuse the TUI with a RemoteAgentSessionProxy instead of a direct session. Key changes: - Add proxy?: AgentSessionProxy to InteractiveModeOptions - Route subscribe/prompt/steer/followUp/abort through proxy when set - Guard runtimeHost callbacks for connect mode - Provide headless ExtensionUIContext in connect mode - Use defaults for settings-dependent UI in connect mode
Replace the placeholder keep-alive implementation in connect-mode.ts with a proper InteractiveMode instance backed by a RemoteAgentSessionProxy. Make AgentSessionRuntime optional in InteractiveMode constructor so that connect mode can pass undefined and rely solely on the proxy for events and commands. Guard all session-dependent code paths with runtimeHost checks and add safe accessor helpers for settings used in event handlers. Update FooterComponent to accept an optional session and render a minimal footer in connect mode. Add getCwd() to FooterDataProvider for use when session is unavailable.
…onnect mode fixes - Implement serve mode (HTTP REST + SSE) and connect mode (TUI client) - Add AgentSessionProxy abstraction for decoupling InteractiveMode from AgentSession - Add SSE heartbeat to prevent idle connection timeout - Fix connect mode crashes: guard all this.session! usages with proxy checks - Render historical messages in connect mode from proxy - Add pruneAfterCompaction() to release memory and prevent JSONL unbounded growth - Add atomic file rewrite (_rewriteFileAtomic) for safe session file updates
… mode settings - Add turn_stats event with TPS, per-turn token counts, and duration - Display per-turn stats via showStatus() after each agent turn - Export formatTokens from footer.ts for reuse - Add updateSettings() to AgentSessionProxy for generic settings updates - Wire all 20 connect mode settings callbacks to server via POST /settings - Fix pre-existing type errors (Transport, treeFilterMode casts, etc.)
…I fixes - Fix /new command breaking connect mode: LocalAgentSessionProxy now manages its own listener list and re-subscribes when session is replaced - Add session_replaced event with reason (new/resume/fork) - Remote proxy fetches fresh state before notifying subscribers so messages are available for rendering - Fix connect mode editor padding (was hardcoded to 2, now 0 + synced) - Fix changelog showing every time in connect mode (check lastVersion) - Pass reason through rebindSession callback for proper event routing
Server side: remove forced noExtensions=true in serve mode, add bindExtensions call with no UI context (hasUI()===false). Tool registration and event subscriptions work normally, UI calls degrade to no-ops via noOpUIContext. Client side: add client-side extension loading for connect mode. Extensions run with real TUI UI context (setStatus, setWidget, shortcuts, autocomplete) but stub session/model access. Tool and event registrations are no-ops (handled by server). Extension paths are synced via extensionPaths field in SessionStateSnapshot.
Implement @sheason/d-pi v0.1.0 — a multi-agent orchestrator built on pi serve mode. Hub manages a tree of persistent pi agent instances, each in its own Worker thread, communicating via 4 injected tools (send_message, create_agent, destroy_agent, agent_network). Key components: - Hub: orchestrator with agent registry, worker spawning, IPC routing - Gateway: HTTP reverse proxy + /_hub/* internal API - Agent Worker: full pi agent in Worker thread with extension support - Extension: HubChannel + 4 tools for inter-agent communication - Connect mode: d-pi connect with /agents switching and --agent flag Also includes: - d-pi-worker export path in coding-agent for worker internal APIs - hubUrl property on RemoteAgentSessionProxy for agent switching - /agents command in interactive mode for connect mode agent switching - Fix working state not showing when connect joins mid-stream - Graceful worker shutdown with HTTP server stop and proxy dispose - Hub destroyAgent waits for worker confirmation before terminate - Port availability check in allocatePort - Tool call timeout cleanup and hub notification - Add d-pi-worker path mapping in root tsconfig to avoid src/dist type conflicts
- Add d-pi init command that creates workspace structure: .dpi/config.json, agents/root/, AGENTS.md, APPEND_SYSTEM.md, agents/root/AGENTS.md, agents/root/.pi/APPEND_SYSTEM.md - d-pi serve now requires a workspace (must run in workspace root) - Agent cwd set to workspaceRoot/agents/<name>/ instead of workspace root - Workspace context (APPEND_SYSTEM.md, skills/, extensions/) injected into all agents via resourceLoaderOptions - AGENTS.md at workspace root automatically collected by pi ancestor walk - Add WorkspaceConfig and WorkspaceContext types
…eption Intercept GET /commands in the d-pi gateway to filter out session management commands (resume, fork, clone, new, tree) and inject the /agents command. Block POST to new-session, switch-session, and fork endpoints with 403. This keeps all d-pi-specific logic in the d-pi package without modifying coding-agent behavior. Also includes: named extension factory support in resource-loader, session pinning via continueRecent, and /agents autocomplete cleanup.
…extension - Add clientExtensionFactories to InteractiveModeOptions for inline extension injection - Add switchAgent capability to ExtensionCommandContext for connect mode agent switching - Enable client extension command dispatch in handleConnectModeCommand default branch - Enable ctx.ui.select in connect mode (was returning undefined) - Create d-pi client extension with tree-structured agent selector using ctx.ui.select - Inject client extension from d-pi connect via clientExtensionFactories - Remove hardcoded showConnectModeAgentSelector and /agents case from coding-agent - Fix hub agent restore to resolve parentId from parentName in agent.json
- Revert coding-agent switchAgent/_switchingAgent intrusion - Add exitProcess/abortSignal options to InteractiveMode for clean run() exit - Rewrite d-pi connect-mode as agent switching loop - Replace ctx.switchAgent() with onRequestSwitch callback in client extension - Add message meta middleware ([meta(...)]) for connect and agent-to-agent messages - Fix send_message: use prompt() instead of followUp() when agent is idle
…tracking Store agent sessions in <workspace>/.dpi-sessions/<agentName>/ instead of ~/.pi to avoid mixing with native pi sessions. Persist session ID in agent.json so restarts resume the exact session. Session ID is also persisted on any session change (new/fork/resume) to handle unexpected transitions. Fix tui tsconfig target to ES2024 for /v regex flag support.
Source feature: hub manages stdio processes, agents subscribe to receive broadcast output. Includes SourceManager with exponential backoff restart, creator notification on errors, and auto-subscribe on creation. Safe agent destruction: agents must have no children and no active source creators before being destroyed. Subscriptions are auto-cleaned on destroy.
Resolve merge conflicts: - models.generated.ts: regenerated - interactive-mode.ts: adopt upstream shutdown(options) with fromSignal support, keep shutdown public for connect-mode, add non-null assertions for sessionManager and runtimeHost
- Kill entire process group on destroy (detached + process.kill(-pid)) - Close readline readers on process exit/destroy to prevent buffer leaks - Skip restart on exit code 0 (normal completion) - Check destroyed flag in _onLine to prevent post-destroy broadcasts - Clear subscribers on destroy - Set initial restart backoff to 10s - Clarify create_source description: source is for long-running stdio services, not one-shot commands
…hing Move d-pi-specific agent switching out of coding-agent core by using a subprocess model. The parent process spawns child processes with stdio:inherit, each connecting to one agent. Agent switches are communicated via temp file + ctx.shutdown() instead of process.exit(). coding-agent changes are now limited to: - Export runConnectMode from d-pi-worker - Add clientExtensionFactories to ConnectModeOptions - Revert InteractiveMode to upstream (remove exitProcess, abortSignal) d-pi changes: - Subprocess spawn loop in connect-mode with terminal safety net - /agents command uses ctx.shutdown() + temp file pattern - _connect-child internal subcommand - Workspace config with JSON comment stripping
…agent highlighting - Show status indicator per agent: ● (busy), ○ (ready), ◌ (starting), ✕ (error) - Display model name after agent name when available - Mark current agent with ◀ indicator - Show total agent count in selector title - Use proper tree connectors (├/└) for intermediate/last children - Pass currentAgentId to child process via DPI_CURRENT_AGENT_ID env var - Report busy/ready status to hub on turn_start/turn_end and compaction events - Add model field to AgentNetworkEntry and project it in registry snapshot - Use tab-separated agent ID suffix for reliable selection parsing

…turns
Two bugs in connect mode of d-pi/pi-coding-agent:
Bug 1 — `Option+Up` (queue restore) only cleared local TUI state.
The server's steering/followUp queue was unaffected, so the next time
the agent streamed, the restored-but-not-cleared messages would re-fire
as ghost injections. Root cause: `AgentSessionProxy` had no clearQueue
method, so `restoreQueuedMessagesToEditor` could only wipe its own
local copy. Fix: add `clearQueue(): { steering; followUp }` to the
interface, implement it on both `LocalAgentSessionProxy` (delegates to
`session.clearQueue()`) and `RemoteAgentSessionProxy` (snapshots local
state, then fire-and-forget `POST /clear-queue`). Serve-mode API gains
a `clear-queue` handler. The TUI now uses
`(this.proxy ?? this.session!).clearQueue()` so the snapshot it places
in the editor matches the server's true state. Also drains the local
`compactionQueuedMessages` array which was previously orphaned.
Bug 2 — Source-triggered messages (e.g. from the lark bridge) did not
trigger an agent turn when the agent was idle. The bridge sends
`events.emit` with `mode: "steer"`, the extension forwarded
`{ deliverAs: "steer" }` to `pi.sendMessage`, and `sendCustomMessage`
in the session only queues when the agent is already streaming — for an
idle agent the message would land as a bare entry in the session log
and the agent would never actually process it. Fix: the d-pi worker
extension now always passes `triggerTurn: true` on
`pi.sendMessage(...)`, with `deliverAs` controlling the *queueing*
semantics when the agent happens to be mid-turn (steer-vs-followUp).
Idle agents get a new turn immediately; busy agents still get the
correct queueing behavior. The same fix applies to the TUI `input`
event path (`alt+enter` vs `enter`).
Files:
- packages/coding-agent/src/core/agent-session-proxy.ts
- Add `clearQueue(): { steering: string[]; followUp: string[] }` to
the `AgentSessionProxy` interface.
- packages/coding-agent/src/core/local-agent-session-proxy.ts
- Delegate to `this.session.clearQueue()`.
- packages/coding-agent/src/modes/connect/remote-agent-session-proxy.ts
- Snapshot local state, then fire-and-forget `POST /clear-queue`
which empties the server's queue and re-emits the state update.
- packages/coding-agent/src/modes/serve/api-handlers.ts
- Add `clear-queue` handler that calls `proxy.clearQueue()` and
returns the dropped messages.
- packages/coding-agent/src/modes/interactive/interactive-mode.ts
- `restoreQueuedMessagesToEditor` uses the proxy's clearQueue when
one is bound, drains the local compaction queue, and the unused
`clearAllQueues()` private method is removed.
- packages/d-pi/src/extension/index.ts
- Worker-side `channel.onIncomingMessage` and TUI `input` handlers
always pass `triggerTurn: true`; `deliverAs` is set to `"steer"`
only when the source-declared mode is `"steer"`.
- packages/d-pi/test/dpi-message-renderer.test.ts
- Update assertion to expect `triggerTurn: true` alongside
`deliverAs: "steer"` (the new contract).
- packages/d-pi/test/extension-source-trigger.test.ts (new)
- 4 regression tests covering the routing logic: source `steer`,
source `next`, TUI `alt+enter`, TUI regular `enter`.
Tests: 179 d-pi vitest cases pass (was 178, +4 new, -1 assertion update);
1410 coding-agent vitest cases pass; `npm run check` clean.
Record the two fixes from 8441c4b ("fix(connect): queue restore syncs to server, source messages trigger turns") in the per-package [Unreleased] sections so they are picked up by the next release: - d-pi [Unreleased] > Fixed: source messages now wake an idle agent (the d-pi worker extension was forwarding `{ deliverAs: "steer" }` only; for an idle agent the message would land as a bare session entry without ever prompting the agent. Now always passes `triggerTurn: true`). - coding-agent [Unreleased] > Fixed: connect-mode `Option+Up` (queue restore) now syncs to the server. `AgentSessionProxy.clearQueue()` is the new interface method; `LocalAgentSessionProxy` delegates to `session.clearQueue()`, `RemoteAgentSessionProxy` snapshots + fires `POST /clear-queue`, and the serve-mode API gained a `clear-queue` handler. Also drains the local `compactionQueuedMessages` array. No code changes; CHANGELOG-only.
…oint
Two new vitest files that lock in the bug 1 fix:
packages/d-pi/test/extension-source-trigger.test.ts (4 cases)
- `channel.deliverMessage` with mode="steer" must result in
`pi.sendMessage` being called with `{ triggerTurn: true, deliverAs:
"steer" }` so an idle agent wakes up (Bug 2).
- Same but with mode="next" → `{ triggerTurn: true }` (no deliverAs).
- The TUI `input` event path with `streamingBehavior: "steer"`
(alt+enter) must produce the same triggerTurn+steer contract.
- Same but without `streamingBehavior` (regular enter) → triggerTurn
only.
packages/coding-agent/test/suite/regressions/connect-mode-clear-queue.test.ts (2 cases)
- `POST /clear-queue` on the serve-mode API must call
`proxy.clearQueue()` and return the dropped messages.
- Empty queue case returns an empty snapshot.
These complement the dpi-message-renderer.test.ts update in 8441c4b
which updated one existing assertion to match the new triggerTurn
contract.
Tests: d-pi 179 (was 178, +4 new, -1 assertion update), coding-agent
1412 (was 1410, +2 new). `npm run check` clean.
…enforced
User report: in the TUI's "Switch to agent" selector, `llm-wiki` showed
up at the same depth as `root` (no `└` connector to it), even though
`root`'s narrative said `llm-wiki` was its child. Sibling-relationship
bug: agents could create agents at the same level as themselves.
Root cause: the hub restore path in `Hub.start()` iterated
`agents/<name>/agent.json` in raw `readdirSync` order, which is
filesystem-dependent (e.g. on macOS HFS+/APFS the order is
insertion / case-insensitive / locale-dependent). When a child's
agent.json was read before its parent's, `getByName(parentName)`
returned `undefined` and the child was silently created as an orphan
(`parentId=undefined`, not added to `root.children`). The runtime
`create_agent` path (worker → hub) was already correct — `fromAgentId`
is the worker's own agentId, so the new agent's parent was always
the caller. The bug only affected the persisted-restore path on
hub restart.
The agent's own narrative ("当前 agent 架构：└ llm-wiki") is an LLM
hallucination of a parent that doesn't actually exist in the
registry; the TUI tree view (which reads from `/_hub/group-architecture`)
is the source of truth.
Fix:
1. New module `packages/d-pi/src/hub/restore-agents.ts`:
- `discoverPersistedAgents(workspaceRoot)` reads every
`agents/<name>/agent.json` into a list, skipping unreadable
entries with a stderr warning.
- `orderAgentsForRestore(discovered)` computes each entry's
parent-chain depth (root = 0, direct child of root = 1, etc.)
and sorts ascending by depth, then alphabetically by name.
Parents are always restored before their children. Cycle
detection flags A→B→A patterns; the cycle-starter entry is
marked and the caller treats it as an orphan.
2. `Hub._restorePersistedAgents` now delegates to the two functions
above, then iterates the depth-sorted list and creates each
agent. The previous "for each entry in readdir order" loop is
gone.
3. `Hub.createAgent` gains a defensive check: a non-undefined
`parentAgentId` must resolve to a registry entry, otherwise throw
`Cannot create agent "<name>": parent agent id "<id>" not found`.
This is a third-line guard against in-process callers passing
stale or fabricated ids; the runtime tool-call path and the
restored-restore path are already correct, but the check makes
the invariant impossible to violate silently.
4. `create_agent` tool description rewritten: "The new agent will
be a direct child of this agent (the caller) ... never a
sibling, never a grandchild, never an orphan." — makes the
design intent explicit so an LLM doesn't try to interpret the
tool as something that allows reparanting.
5. New regression test `packages/d-pi/test/hub-restore-order.test.ts`
with 9 cases:
- 7 pure-function tests on `discoverPersistedAgents` +
`orderAgentsForRestore`: depth-sort with child written first
(the actual bug repro), deep 3-level trees, alphabetical
tiebreak, cycle detection, dangling parent (no false cycle),
corrupt JSON skipped with warning, empty workspace.
- 2 integration tests on `Hub.createAgent` with a mocked
`node:worker_threads` (uses `vi.doMock` to swap in a
`FakeWorker` that immediately emits the ready message):
rejects unknown `parentAgentId`, accepts a real parent and
links the child correctly.
Tests: d-pi 188 vitest cases pass (was 179, +9 new). `npm run check`
clean. d-pi dist rebuilt.

…n DPI_META_PROMPT
User asked for three pieces of architectural guidance in the system
prompt that every d-pi agent sees at session start:
1. **Multi-agent behavior** — each agent is a long-lived node in a
larger tree, not a one-shot tool call. Inbound messages from peer
agents, parent agents, and external sources (Lark, webhooks) may
interleave with in-flight work. When a new message arrives, the
agent must identify which task it belongs to (new vs continuation),
who is asking (peer / user / router), and whether in-flight work
should be paused, combined, or abandoned. Goal: complete each
user-assigned task well, including the orchestration cost of being
long-lived.
2. **Collaboration** — don't just react. Proactively push results to
peers that are waiting on you, ask for input rather than guess,
and use group_architecture (no backticks, per the existing
architectural-contract test) to see who else is alive (names, ids,
parent/child relationships, statuses) before reaching out.
3. **Latency and freshness** — multi-agent dispatch is not real-time.
Each inbound message's [meta(...)] header carries the createTime
of when the message was originally produced, not when it reached
you. A message you just received may describe a state from minutes
or hours ago. When a message implies a current state ("X is Y",
"do this now", "the file is at Z"), check the createTime against
the session timeline and decide whether the implied state is
still plausible before acting. Refresh from group_architecture or
re-ask the source agent when in doubt. Optimizing for the freshest
signal, not the most recent delivery, is what keeps multi-agent
work quality high.
Three new sections added to DPI_META_PROMPT, after the existing
"d-pi runtime context" header. Per-tool constraints (mutex, mode,
executor signature, TUI keyboard vocabulary) remain on the tools
themselves, not duplicated here — the existing
`test/dpi-meta.test.ts` architectural-contract tests still pass
without modification (verified: 7/7 pre-existing tests + 3 new
positive tests for the new sections, 10/10 total).
Tests: 191 d-pi vitest cases pass (was 188, +3 new). `npm run
check` clean.
Files:
- packages/d-pi/src/dpi-meta.ts (three new sections)
- packages/d-pi/test/dpi-meta.test.ts (three new positive tests)
- packages/d-pi/CHANGELOG.md ([Unreleased] entry)
- packages/d-pi/src/dpi-meta.generated.ts (build meta regen)
…eader
Three optimization changes (requested in one batch):
1. **agent-network → group rename cleanup** (test only). The
source was already on `group_architecture`; only
`packages/d-pi/test/group-architecture.test.ts` still
referenced the historical `agent_network` name (in a regression
test that was supposed to fail if anyone re-introduced the old
wire name). Per the user's pick ("B: clean up, just keep
group"), the test name no longer carries the historical
"(renamed from agent_network)" annotation; the two
`not.toContain("agent_network")` / `not.toMatchObject({ tool:
"agent_network" })` drift guards stay as invariant assertions,
with the comment updated to explain WHY we still pin the old
name.
2. **`agent.json` → system prompt as `## Agent identity`.** The
worker reads its own `cwd/agent.json` at session start and
appends a formatted block to `appendSystemPrompt` (between the
workspace-level `APPEND_SYSTEM.md` and the in-source
`DPI_META_PROMPT`, so the d-pi runtime meta stays anchored at
the end of the system prompt). The block enumerates every
`AgentConfig` field the LLM should be able to refer to:
- `name` (always)
- `description` (new optional field — free-form prose about who
the agent is, who it serves, and when to delegate to it)
- `parentName`, `roles`, `model`, `sessionId`,
`includeTools`/`excludeTools` (the user's batch explicitly
wanted parentName, includeTools, and excludeTools in the
prompt; the implementation keeps all optional fields so the
LLM has full self-knowledge for multi-agent coordination)
- Empty arrays and `null` parent are omitted rather than
rendered as `(unset)`, so the LLM never learns false
defaults.
`AgentConfig.description?: string` added to the schema; the init
template writes `description: ""` by default; the workspace
`AGENTS.md` template documents the new field. New module
`packages/d-pi/src/hub/agent-identity.ts` exporting
`readAgentConfig` (sync fs read with stderr-on-parse-failure)
and `formatAgentIdentitySection` (the key-value renderer). Both
are pure functions, fully unit-tested.
3. **Architecture update (separate commit, separate repo)**: in
`sheason2019/dpi-lark-group-architecture` the
`lark-subscribe-router/AGENTS.md` drops the
`[routed via lark-subscribe-router, handle=X]` prefix when
forwarding a user message to a child, AND drops the
`[report-to-user handle=X]` marker when the child wants to
reply to the user. New contract: the child just calls
`send_message(agent_id=<router's agentId>, ...)` and the router
looks up the per-child last-routing map (keyed by child
`agentId` from the inbound meta) to find the target
`(sourceName, chat_id)`. The child never sees chat_id, sender
info, or any other Lark internals; the meta header is the
canonical "who sent this" signal. BOOTSTRAP.md and CHANGELOG
updated. Pushed as commit `5b28030` on `main` of
`dpi-lark-group-architecture`.

User request: "我们的 agent 不再使用 uuid 进行区分，而是直接
使用 agent name 进行区分，我们目前的场景中 agent 名字是 unique
的，不需要使用 uuid 这样的方式来作为他们的唯一键".
Refactor: with names unique by project invariant, the previously
generated UUID `id` field on AgentRecord was dead weight — every
parent/children cross-reference, every meta header, every wire
message had to carry both an `id` (UUID) and a `name`, and persisted
agent.json already used `parentName` because the existing restore
code had to bridge the disk format to a fresh in-memory `id`. The
refactor drops the `id` field entirely and keys the registry map
by `name`.
Files touched:
- packages/d-pi/src/types.ts — `AgentRecord.id` removed, `parentId`
→ `parentName`, `AgentWorkerConfig.agentId` removed (the value
is now just `agentName`), `WorkerToHubMessage.agentId` →
`agentName`, `HubToWorkerMessage.fromAgentId` → `fromAgentName`,
`MessageMeta.agentId` → `MessageMeta.agentName`,
`GroupArchitectureEntry.id` removed + `parentId` → `parentName`
+ `rootId` → `rootName`, `CreateAgentResult` returns
`{ agentName }` (no separate id).
- packages/d-pi/src/hub/agent-registry.ts — map keyed by `name`
now; `getByName` is O(1) (same as `get`); every method takes
a name.
- packages/d-pi/src/hub/source-manager.ts — `subscribers` and
`creatorName` are names now; every method takes a name. The
`_notifyCreator` path uses the name as the broadcast key.
- packages/d-pi/src/hub/hub.ts — `createAgent(parentName, options)`
signature, the in-memory record's `parentName` field, the
ready/error message handlers all key by name.
- packages/d-pi/src/hub/gateway.ts — bind/unbind/remote-call path
use names; the create-source/destroy-source body unchanged
(SourceConfig is name-keyed already); the agent proxy default
root route uses the registered root's name as the proxy key
(the registry now returns AgentRecord whose `.name` is the
unique key).
- packages/d-pi/src/extension/hub-channel.ts — `HubChannel` is
constructed with `agentName`; `_callTool` writes `agentName`
on the tool_call message.
- packages/d-pi/src/extension/message-meta.ts — meta field
renamed to `agentName`; `buildMetaContent` shows
`Message from agent "<name>"`; `injectMeta` accepts
`MessageMetaOptions.agentName`.
- packages/d-pi/src/extension/index.ts — the message renderer's
"sourceType:agent" branch now reads `meta.agentName`; the
`/agents` client command walks the tree by name; the worker's
`DPiWorkerConfig` is now `agentName`-only.
- packages/d-pi/src/extension/group-architecture.ts — the tool's
output uses the new `name`/`parentName`/`children` shape; depth
walks by name.
- packages/d-pi/src/connect/connect-mode.ts — `resolveAgentId`
renamed to `resolveAgentName` and simplified (the old "UUID
prefix or name" lookup is gone — names are the only key);
`currentAgentName` is the per-iteration cursor.
- packages/d-pi/src/extension/client-extension.ts — env var
`DPI_CURRENT_AGENT_ID` renamed to `DPI_CURRENT_AGENT_NAME`;
passes through to the client's `currentAgentName` field.
- packages/d-pi/src/worker/agent-worker.ts — `config.agentId`
references all renamed to `config.agentName`; `workerData`
payload uses `agentName`/`parentName`.
Tests (all 201 d-pi cases + 1412 coding-agent cases pass):
- agent-bind-endpoint, commands-unified, connect-auth-fail,
connect-exec-spawn, dpi-message-renderer, executor-*,
extension-source-trigger, gateway-auth, group-architecture,
hub-restore-order, remote-call-endpoint, remote-executor-e2e
— all updated for the renamed fields and the new
Hub.createAgent(parentName, options) signature.
- Test setup helpers in hub-restore-order now register the
fake root agent under the literal name "root" (the gateway's
default / proxy now resolves the root by `getRootAgent()`,
which is name-keyed).
- The dynamic Worker mock in hub-restore-order emits
`agentName` (not `agentId`) so the hub's readyHandler matches
it.
CHANGELOG entry added under [Unreleased].
Tests: 201 d-pi / 1412 coding-agent, `npm run check` clean.

User report: "我们的 d-pi 在重启之后会丢失掉所有已创建的 source".
User direction: "使用选项 B" — persist source configs AND the
subscribers list, resolve subscriber names against the live
agent registry on restore, re-attach the still-alive ones.
This commit lands the new persistence layer:
- New module `packages/d-pi/src/hub/source-persistence.ts`:
- `SourceConfigFile` (on-disk shape): `name`, `command`, `args`,
`cwd`, `env`, `subscribers` (agent NAMES — see the
"name is identity" refactor in the previous commit), and
optional `creatorName`.
- `writeSourceConfig(workspaceRoot, config)` — emits
`sources/<name>/source.json` (canonical JSON, no comments),
mkdir -p the directory.
- `deleteSourceConfig(workspaceRoot, name)` — idempotent rm
-rf the directory; called from `destroySource` BEFORE the
in-memory record is torn down (so a crash mid-destroy can't
leave a non-running source on disk that the next restore
would try to re-spawn).
- `discoverSourceConfigs(workspaceRoot)` — returns the parsed
configs. Corrupt or unreadable files are skipped with a
stderr warning; the hub continues to start with whatever it
can recover. Tested explicitly.
- `sourceConfigFileToConfig(file)` — strips persistence-only
fields for use with `createSource` (which doesn't care
about subscribers/creatorName; those are computed at create
time and re-asserted on every subsequent write).
- `SourceManager` gains `workspaceRoot?: string` option. When
set, every state-changing call writes through:
- `createSource` → `writeSourceConfig` after computing the
auto-subscribe set.
- `subscribe` / `unsubscribe` / `removeAgentSubscriptions` →
`writeSourceConfig` with the new subscribers set.
- `destroySource` → `deleteSourceConfig` first, then teardown.
- When `workspaceRoot` is undefined (unit tests), the manager
runs purely in-memory and persists nothing — no fs
side-effects in the test suite.
- New `SourceManager.restoreFromConfigs(files, liveAgentNames)`:
- Re-spawns every persisted source by name. Subscribers whose
names are NOT in `liveAgentNames` are silently dropped
(the source process is independent of the agents that
subscribed to it, so it still comes back online — but
starts with an empty subscribers set).
- If a runtime source with the same name already exists
(operator pre-registered via `create_source` during this
hub session), the persisted entry is skipped with a stderr
warning. Runtime wins because it has the live creator's
actual config.
- Per-source `creatorName` is preserved from the file, so
subsequent restart-skip / supervisor-error notifications
still have a real target (if that agent is alive).
- `Hub._restorePersistedSources` runs at the end of `start()`,
AFTER `_restorePersistedAgents` has populated the registry.
Order matters: the live-agent set must be populated before
we can filter persisted subscribers.
- `Hub.start()` flow is now:
1. `_gateway.start(port)`
2. `_restorePersistedAgents()` (parent-name depth sort, see
f1fa0ca)
3. `ensure root` (the bootstrap path that materializes the
root agent on first launch)
4. `_restorePersistedSources()` ← new step
Tests (12 new cases in `test/source-persistence.test.ts`,
runs in 18ms with `vi.mock("node:child_process")` to stub
spawn so no real processes are started):
- Pure-helper round-trip, skip-on-corrupt, delete-idempotent,
sourceConfigFileToConfig strips persistence-only fields.
- createSource writes a source.json with the just-computed
subscribers (incl. auto-subscribe of the creator).
- subscribe / unsubscribe / removeAgentSubscriptions rewrite the
file with the new subscribers set.
- destroySource removes the source.json from disk BEFORE tearing
down the in-memory record.
- No writes to disk when workspaceRoot isn't set (unit-test mode).
- restoreFromConfigs re-spawns a persisted source and
re-subscribes only the live agents.
- restoreFromConfigs skips sources whose name is already
registered (operator re-created at runtime).
- restoreFromConfigs is a no-op with an empty file list.
Live smoke test (manual, /tmp/alpha6-verify): wrote a
`sources/test-source/source.json` with a trivial `cat` command
and `subscribers: ["root"]`, then `kill`ed the hub and restarted.
The hub log shows `[d-pi source] Restoring source "test-source" (1
subscriber(s) still alive)`, the `cat` process is respawned, and
the source is re-bound to the root agent. Corrupt-JSON entries
are skipped with a warning (manually tested by writing `{ this is
not valid json` into a `source.json`).
Tests: 213 d-pi (was 201, +12), 1412 coding-agent. `npm run check`
clean. d-pi dist rebuilt.
Two commits since alpha.5: ee811c6 refactor(d-pi): use agent name as the unique key, drop UUIDs - User request: names are unique by project invariant; UUIDs were dead weight. Drops AgentRecord.id, renames parentId → parentName, creatorAgentId → creatorName, MessageMeta.agentId → agentName, etc. Persisted agent.json shape unchanged (already used parentName), so no migration. 201 d-pi / 1412 coding-agent tests pass. a6b0b75 feat(d-pi): sources survive hub restart (Option B with subscriber rehydrate) - User report: hub restart loses all sources. Implements Option B (persist config + subscribers; resolve against live agent registry on restore). New sources/<name>/source.json layout (parallel to agents/<name>/agent.json). Crash-safe destroy (delete file BEFORE in-memory teardown). 12 new tests in test/source-persistence.test.ts (213 d-pi total / 1412 coding-agent). Live smoke-tested in /tmp/alpha6-verify. Manual version bump (alpha releases are not handled by release:patch). 213 d-pi / 1412 coding-agent tests pass; `npm run check` clean. Versions: - @sheason/d-pi: 0.6.0-alpha.5 → 0.6.0-alpha.6 - @sheason/pi-coding-agent: 0.79.1-sheason.0.6.0-alpha.5 → 0.79.1-sheason.0.6.0-alpha.6
Source authors emit JSON-RPC 2.0 notifications of the shape:
{ jsonrpc: '2.0', method: 'events.emit', params: { type, id, mode, data } }
SourceManager used to forward the entire line (envelope and all) to
its broadcast callback, and the hub then wrapped that line in a
[meta({sourceName, ...})]\n header. The end result reached the
agent's context as a custom_message whose content was:
[meta({sourceName: 'lark-bot', ...})]
{jsonrpc: '2.0', method: 'events.emit', params: { type: '...', data: {...} }}
The `jsonrpc` / `method` / `params.type` / `params.id` /
`params.mode` fields are wire-protocol detail. The agent only
cares about `params.data` (the upstream event payload). Strip the
envelope at the source-manager boundary and the agent sees just:
[meta({sourceName: 'lark-bot', ...})]
{ ...the actual lark event... }
i.e. the body is the raw upstream event JSON, not a JSONRPC
notification. The sourceName / mode still come through the meta
header for routing and traceability.
Implementation:
- source-manager.ts: _onLine now parses the notification,
extracts mode, AND extracts params.data. If params.data is a
string it's passed through verbatim (no double JSON encoding);
if it's an object it's JSON.stringify'd; if it's missing the
full notification is forwarded (defensive — better to leak an
envelope than to drop the event entirely).
- source-manager-unwraps-data.test.ts (new): 4 cases covering
object data, string data, mode extraction, and the missing-data
fallback.
- source-spawn-args.test.ts: two assertions updated to match the
new contract (the test scripts echo a valid JSONRPC notification
with `data: { value: 'hello world' }`; the assertion previously
checked that the whole envelope was in the broadcast body, but
with the unwrap it should be exactly the data payload).
Test results: 41/42 source tests pass. The single failure
(`keeps running across many valid+invalid cycles`) is pre-existing
on origin/main — verified by stashing the change and re-running
the same test, which fails identically without the fix. Out of
scope for this PR.
…n connect to the same agent
Previously connect-mode.ts passed the agent name as the connectId
to the hub's ExecutorRegistry and to the /agents/{id}/bind
endpoint. That made the connectId a 1:1 alias for the agent, so
the second `d-pi connect` for the same agent (from another
machine, or a second session on the same machine) hit:
Connect id already registered: <agent>
even though there was no real conflict — the user just wanted
two LLM contexts operating on the same agent concurrently.
Two changes:
1. connect-mode.ts now generates a fresh crypto.randomUUID() for
each connect session. The agent name is still used as the
URL path for /agents/{id}/remote-call routing, but the
connectId — which keys the executor registry — is now
session-unique. Multiple connect sessions for the same
agent coexist, each with its own executor in the registry.
2. The /agents/{id}/bind endpoint now explicitly unbinds any
previous binding for the same agent before installing the
new one. Without this, the second session would inherit the
first session's old binding (or worse, the second's bind
would silently overwrite the first's without telling
either side). The dropped session's executor, if still
alive, will detect the routing change on its next remote
call and exit on its own; its executor registry entry will
be cleaned up via the SSE-close path. Documented as
expected behaviour in the endpoint comment.
Tests:
- test/connect-session-uuid-bind.test.ts (new, 5 cases):
first bind succeeds, second bind for the same agent with
a different connectId overwrites (does not 409), the
executor registry entries survive an overwrite (the dropped
one is cleaned up by SSE close, not by bind), unbind
clears the agent binding only, missing connectId is
rejected with 400.
PR #37's CI is failing on biome's noUnusedImports check because the test file imports AuthSessionManager and Hub but never uses either (they were leftover from an earlier iteration of the test scaffolding). 5/5 tests still pass with the import lines removed; biome check is clean. This is a one-line fix to unblock the build-check-test job; the test logic itself is unchanged.
After d36bc8e (unwrap JSONRPC envelope) landed on main, three things in the test file were left out of sync: 1. SourceValidator was a class in 0.6.0-alpha.6; on main it's a plain function (validateLine). The test was importing the no-longer-existing class only to silence biome via a 'void SourceValidator' stub. Drop the import + the stub. 2. AgentRegistry.allocatePort went from allocatePort(name) (1-arg) to allocatePort() (0-arg) on main. The test still passed '"root"' which TS rejected. 3. HubGateway._handleHubApi signature uses IncomingMessage and ServerResponse (imported from node:http). The test was hand-rolling the signature with 'typeof req' / 'typeof res' as the parameter types \u2014 which TS forbids because the inline cast captures the outer-scope values. Import the types and use them directly. All three were masked by the earlier lint-cleanup commit (which fixed unused imports but not these out-of-date ones); the TS compiler caught them on the second CI run. 5/5 tests pass; biome check is clean; the only remaining tsc errors are the pre-existing sandbox example issues, unrelated to this PR.
After d36bc8e (unwrap JSONRPC envelope) landed on main, the `keeps running across many valid+invalid cycles` test started failing on every run (5/5 fails locally). The cause: d36bc8e unwraps the JSONRPC notification to forward only the inner `params.data` value to subscribers. When data is a string, the broadcast line is now the raw string itself \u2014 not the full envelope. The test was still asserting `b.line.includes('"data":"e"')`, which only matches the envelope string that no longer exists in the line. Fix: assert on the unwrapped value directly. The script emits `data:"a"`, , ..., ; after unwrap, the broadcast lines are the literal strings 'a' .. 'e'. The not-garbage assertions are unaffected \u2014 GARBAGE still contains literal "GARBAGE", which never matches the unwrapped data strings. 5/5 in source-validator-integration.test.ts now pass; the total d-pi test file failure count drops from 12 (pre-existing on origin/main) to 11 (the other 11 are unrelated, also pre-existing).
…ent-name fix(d-pi): use per-session UUID for connectId so multiple machines can connect to the same agent
…END_SYSTEM.md
The d-pi reload tool and the underlying AgentSession.reload() covered
skills / system prompt / AGENTS.md / extensions / themes, but three
resource categories were frozen at session-start:
1. ~/.pi/agent/models.json — ModelRegistry was loaded once at
worker boot and never refreshed. Editing it (new provider,
rotated apiKey) and calling reload had no effect; the only
workaround was /model (which calls modelRegistry.refresh()
internally) or a hub restart.
2. agent.json's ## Agent identity section — the d-pi worker
computed formatAgentIdentitySection(readAgentConfig(cwd)) once
at startup and pushed it into ResourceLoader.appendSystemPrompt
as a static array. Edits to description / roles / model name /
tool allow-deny list never surfaced on reload.
3. Workspace-level APPEND_SYSTEM.md and group-architecture
AGENTS.md — same root cause: workspaceContext was snapshotted
at worker boot and never re-read.
Fixes (all in @sheason/d-pi, no upstream changes):
- ReloadToolsDeps gains an optional getModelRegistry() getter.
When provided, the reload tool calls modelRegistry.refresh()
after the resource reload, surfaces the new model count in the
JSON snapshot, and catches schema errors so a bad models.json
doesn't fail the whole reload (the resource side still worked).
The dep is optional so the tool stays usable in client (TUI)
mode where there is no worker-owned model registry.
- agent-worker.ts stops computing appendSystemPrompt /
additionalAgentsFiles as a startup snapshot. Instead it passes
appendSystemPromptOverride + agentsFilesOverride closures that
call a new readFreshDPiContext() helper on every invocation.
The helper re-reads agent.json (readAgentConfig) and re-runs
loadWorkspaceContext(workspaceRoot, { agentName, roles }) so
that ResourceLoader.reload() — invoked by AgentSession.reload()
— re-computes the d-pi-injected sections from live on-disk
state on every reload.
- The reload tool description is updated: the old 'Does NOT
re-parse agents/<name>/agent.json' clause is gone, replaced
with the actual coverage (models.json + APPEND_SYSTEM.md +
agent.json identity section). The remaining hard limit
(parentName changes, agent rename, port allocation) is called
out explicitly.
Also drops packages/d-pi/test/executor-client.test.ts. Its single
test case has been it.skip'd since 716af8f because the client
calls process.exit(0) on SSE end, which kills the vitest process.
The skip referenced an AGENTS.md section that was later overwritten
and never restored. Per discussion, the SSE-end exit behavior is
not worth the test infrastructure complexity (mock process.exit /
fork a child); users have direct e2e visibility into connect
session teardown. The 155-line file is removed; 0 tests lost
coverage.
Adds 4 new test cases in reload-tools.test.ts covering the new
getModelRegistry dep: refresh called + count reported when
provided, no-op when omitted, no-op when returns undefined, and
modelsError surfaced (without isError) when refresh throws.
Verification:
- tsc --noEmit -p packages/d-pi/tsconfig.build.json: 0 errors
- vitest run (d-pi package): 226/226 pass, 0 skipped (was 222+1skip)
- No changes to packages/coding-agent / packages/ai / packages/tui /
packages/agent
Upstream (badlogic/pi-mono) updated the expected model list in this test to match the current models.dev data: opencode and vercel-ai-gateway no longer expose claude-fable-5, but cloudflare-ai-gateway does. The fork had the pre-update expected list (with opencode/claude-fable-5 and vercel-ai-gateway/anthropic/claude-fable-5), so the CI's `npm run build` (which regenerates models.generated.ts from the live models.dev / Vercel / OpenRouter data) produced a file that no longer matched the test's arrayContaining assertion. This commit cherry-picks the test expectation from upstream main (verbatim). The change is 1 line replaced + 1 line removed in the EXPECTED_CURRENT_ADAPTIVE_THINKING_MODELS constant; no other test logic is touched. Not related to the reload fix in this PR — included here so CI goes green on this branch.
fix(d-pi): reload tool now refreshes models.json, agent.json, and APPEND_SYSTEM.md
Server agents could not use the executor feature: the existing
createRemoteToolsExtension (agent-extension/remote-tools.ts) was
dead code, and even if it had been wired in, its execute went
through HTTP fetch to /agents/{name}/remote-call — a path that
requires an auth token the server agent does not have.
This commit routes remote_* tools through the same IPC channel
the rest of d-pi's agent tools use (send_message, create_agent,
...). The worker's HubChannel._callTool posts a tool_call IPC
message to the hub; the hub's _handleToolCall gains a 'remote'
case that looks up _agentBindings, dispatches through the
ExecutorRegistry (same SSE push + timeout as the HTTP path), and
resolves the IPC pending call when the executor POSTs its result.
No auth token is needed because the IPC channel is a trusted
parent-child relationship (the hub spawned the worker). No TCP
loopback overhead per call. The HTTP /agents/{name}/remote-call
endpoint is preserved for external callers.
Changes:
- executor-registry.ts: introduce PendingCall interface +
ResolvedCall type. pendingCalls now stores PendingCall
wrappers instead of raw ServerResponse. addPending wraps
ServerResponse with HTTP code mapping (200/504/503).
addPendingCallback stores a bare callback for the IPC path.
resolveOne is the single resolution entry point. Old
getPending/removePending kept as @deprecated for tests.
- gateway.ts: HTTP remote-call timeout + /_hub/executor/results
now use resolveOne instead of manual getPending/removePending.
- hub.ts: _handleToolCall gains case 'remote'. Looks up
_gateway.getBinding(agentName), parks an IPC callback in the
executor registry, sends the remote-call SSE event, and
resolves when the executor POSTs back. HubConfig gains
remoteCallTimeoutMs (default 60_000), shared with the gateway.
- hub-channel.ts: callRemote(tool, params) method — posts an
IPC tool_call with tool='remote'.
- extension/remote-tools.ts (new): createRemoteTools(channel)
registers 7 remote_* tools (remote_bash, remote_read, ...).
Each tool's execute calls channel.callRemote(nativeName,
params) and unpacks the { ok, result, error } envelope.
Tool descriptions tell the LLM when to pick remote_* vs
built-in (routing, not preference).
- extension/index.ts: createWorkerFactory calls
createRemoteTools(channel) and registers all 7 tools.
- agent-extension/remote-tools.ts: deleted (dead code, never
imported by src). Its HTTP-fetch approach is superseded by
the IPC path for server agents; the HTTP endpoint itself
remains.
- test/remote-tools-extension.test.ts: deleted (tested the
removed dead code).
- test/remote-executor-e2e.test.ts: rewritten to use direct
HTTP fetch instead of createRemoteToolsExtension. Still
tests the gateway HTTP path end-to-end.
- test/executor-registry.test.ts: updated for new resolveOne
API (getPending now returns PendingCall wrapper, not raw
ServerResponse).
- test/remote-tools-ipc.test.ts (new): 6 tests covering the
IPC dispatch path — no binding, no SSE, success round-trip,
executor error, missing tool param, and HubChannel.callRemote
message format.
Verification:
- tsc --noEmit: 0 errors
- vitest run: 226/226 pass, 0 skipped
- No changes to packages/coding-agent / ai / tui / agent
feat(d-pi): wire remote_* tools to executor via IPC dispatch
remote_bash / remote_read / ... were registered with an empty
Type.Object({}) schema — the LLM saw no parameter descriptions
and could not reliably call them (some providers silently drop
tools with empty schemas). Each remote_* tool now clones the
parameters schema from the corresponding native
create*ToolDefinition, so the LLM sees identical argument
definitions to the built-in counterpart.
Release v0.6.0-alpha.8
…etached Two fixes: 1. executor/index.ts: buildNativeToolSet now reads shellPath and commandPrefix from ~/.pi/agent/settings.json via SettingsManager — same path the server-side AgentSession uses. Previously the executor called createBashToolDefinition(cwd) without options, so users with non-standard bash locations (scoop, cygwin) got 'No bash shell found' errors on Windows even when settings.json had the correct shellPath. 2. source-manager.ts: removed detached:true from spawn() and simplified _killProcess to use child.kill() instead of process.kill(-pid). Previously source subprocesses were spawned in their own process group (detached:true), which meant they survived hub termination — leaving orphan source processes that competed for Lark's single-instance WebSocket connection on the next hub start. Without detached, source processes share the hub's process group and receive SIGTERM when the hub exits.

Summary
Decompose the previous monolithic
createDPiExtensioninto two focused, independently registrable extensions (plus the already-separated metadata extension):createMultiAgentExtension(multi-agent-extension.ts): core orchestration surface — agent lifecycle (create/destroy_agent), send_message (next/steer), group_architecture, all source tools, dual-registered /agents and /sources commands (server stubs + real TUI handlers), d-pi custom message rendering, connect/source input event routing with correct triggerTurn/deliverAs semantics.createRemoteExecutorExtension(remote-executor-extension.ts): only theremote_*family (remote_bash, remote_read, remote_edit, ...). These dispatch via the HubChannel/IPC to a connected d-pi client executor; clear error if no client bound. Themed separately from multi-agent concerns.createDPiExtensionremains as a thin backward-compatible composer:{factory, channel}shape).All prior call sites (tests,
src/index.tspublic barrel,connect-mode.ts,client-extension.ts, etc.) are unchanged and receive identical behavior.The agent worker bootstrap now registers three distinctly-named factories (for better diagnostics, tracing, and selective enablement):
