feat(tools): add DeepSeek Harness support - #1672
Conversation
📝 WalkthroughWalkthroughAdds DeepSeek Harness ( ChangesDeepSeek Harness integration
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The PR adds DeepSeek Harness as a project-local skills target and is supported by passing validation and test results. Merge readiness is low risk rather than minimal because one supported-tools reference table is incomplete and a repository-controlled .dsh directory can affect automatic selection during non-interactive initialization; both are bounded issues with no demonstrated cross-project or privilege impact.

In @.changeset/add-dsh-support.md:
- Line 5: Update the DeepSeek Harness description in the changeset to clarify
that dsh generates no file-based slash-command adapters while still supporting
skill invocations such as /openspec-*. Replace the ambiguous “skills-only (no
slash commands)” wording without changing the documented dsh paths or invocation
behavior.
In `@openspec/changes/archive/2026-08-15-add-dsh-support/design.md`:
- Around line 81-83: Update the Migration Plan to document rollback for
generated dsh artifacts: reverting the AI_TOOLS entry stops future dsh detection
and generation, but does not remove existing .dsh/skills files; explicitly state
that those files require manual cleanup when removal is desired.
In `@src/core/config.ts`:
- Line 50: Update the DeepSeek Harness entry in getAvailableTools so both .dsh
and .dsh/skills detection signals require directories rather than merely
existing paths, while preserving the existing availability behavior for valid
directories. Add regression coverage for each signal when it is a regular file,
ensuring the tool is not reported as available.

Resolves the docs conflict with Zed Agent support (Fission-AI#1659), which landed on main while this PR was open. Both tools add a row to the same five tool tables, so each side dropped the other; the resolution keeps both in every list, in alphabetical order. Also normalizes this branch's `dsh`(shorthand for DeepSeek Harness) to a plain `dsh` so it matches how every other tool id is written, and drops a trailing space it introduced in docs/cli.md.

Reviewed at 4b79c20. DeepSeek Harness paths, priority, Git-root discovery, and customSkillDirs guidance match current upstream behavior; init and update preserve skills-only ownership safely. Build and all 432 focused tests pass.

Status
LGTM for final human review. Implementation and verification are complete at
4b79c2015. GitHub CI and Security passed, including Linux, macOS, and Windows tests. Only the required human PR review remains outstanding. Not merged.What was missing / the motivation
DeepSeek Harness reads project skills from
.dsh/skills, but OpenSpec had no dedicated target. A registry entry lets DSH users initialize and update their native skill tree through the existing pipeline.What it does
openspec init --tools dsh, generating.dsh/skills/openspec-*/SKILL.mdwith/openspec-*references and no command adapter..dshno longer falsely selects DSH; no new detection flags or changes to other tools are needed..agentsskills.mainis merged into this branch without conflicts.Proof it works
git diff --check: passed..dshfiles are not detected as tool directories.Notes / limits
Final tests used isolated home/config/shell state and localhost access. Earlier runs exposed host MiniMax/Oh My Zsh state and an npx-located Node binary affecting unrelated tests; the clean full run passed without changing those tests or production code.
Commands-only delivery intentionally keeps existing adapterless behavior: no DSH workflows, with corrective guidance. A file blocking
.dsh/skillsremains an ordinary filesystem error, as for other tools.No new live DSH model session or browser-rendered documentation check was run. Cross-platform CI and Security passed for this revision: CI, Security.
The latest automated review only flagged pre-existing missing rows for other tools in
docs-lab/reference/supported-tools.md; that separate documentation cleanup is outside this DSH integration.Closes #1681
