Standalone CLI derives wrong agent labels from the encoded project dir

[McGars]

Version: pixel-agents@1.4.0 (standalone CLI, macOS, Node 25.9)

Summary

In standalone CLI mode, the label shown above a character is derived by splitting Claude Code's
encoded project-directory name on - and taking the last segment. That encoding is lossy — Claude
Code replaces both / and _ with - — so the last segment is frequently not the folder name.

Result: several unrelated projects render with the same meaningless label.

Reproduce

1. Have Claude Code sessions in folders whose names contain _ or -, e.g.
   ~/work/acme/mobile_client_new.
2. Run pixel-agents --port 3100, enable Settings → Watch All Sessions.
3. Enable Always show labels.

Observed

encoded project dir	label shown	actual folder
-Users-<u>-personal-ai-work	work	personal_ai_work
-Users-<u>-work-acme-mobile-client-new	new	mobile_client_new
-Users-<u>-workflow-my-openclaw	openclaw	my-openclaw
-Users-<u>-workflow-my-openclaw-skills-report-subagent	subagent	report-subagent

Three concurrent sessions from the same repo all render as new, so characters are
indistinguishable.

Root cause

dist/cli.js:

function fs(t){ let e = t.replace(/^-+/,"").split("-"); return e[e.length-1] || t }

It is used only as the fallback branch of a resolver hook that the VS Code adapter supplies:

let h = Rt?.({ cwd: n, projectDir: u }) ?? fs(w.basename(u));

In standalone mode Rt is undefined, so the lossy fallback is always taken. The information needed
to undo the encoding is not present in the directory name — but it is present in the transcript:
every .jsonl record carries the real cwd.

$ head -1 ~/.claude/projects/-Users-<u>-work-acme-mobile-client-new/<session>.jsonl | jq -r .cwd
/Users/<u>/work/acme/mobile_client_new

Suggested fix

Provide an Rt implementation for standalone that reads cwd from the newest .jsonl in the
project dir and returns path.basename(cwd), falling back to the current behaviour on any error.
The first call site already has cwd in scope and could pass it straight through.
