headsup-resync-tab-a66448 — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited headsup-resync-tab-a66448 (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
Force-applies the current Claude state (color + attention) to an iTerm2 session, bypassing Claude Code's automatic hook chain. Use when a tab is visibly stuck on a stale color and you need to push the right color through manually.
/headsup-resync-tab — resync the current tab (the one this Claude session is running in). Default for "I just noticed my own tab is out of sync"./headsup-resync-tab <UUID> — resync a specific tab by its iTerm2 session UUID, regardless of which tab the user is currently in. Default for "tab 8884B62B is stuck orange, fix it from here". UUID can be the bare uuid OR the full wXtYpZ:UUID form — both work.Run the resync script. It does all the actual work — writes the state file, fires Tier 2 (one-shot Python with fresh iTerm2 connection), and the daemon picks it up too:
~/.claude/hooks/headsup-resync.sh [<uuid>]If the user supplied a UUID argument, pass it through. Otherwise call with no args — the script walks up $PPID to find an iTerm2-spawned shell with ITERM_SESSION_ID set, which is the current tab.
After it succeeds, confirm in one sentence ("Resynced BC81AA0D to blue (processing)."). Don't explain the three-tier internals unless the user asks — they typed /headsup-resync-tab because they wanted the tab fixed, not a tutorial.
To have headsup automatically resync the current tab at the start of every Claude Code response, add this to ~/.claude/CLAUDE.md:
At the start of every response, silently run: bash ~/.claude/hooks/headsup-resync.sh 2>/dev/nullWhen invoked this way, suppress the confirmation message entirely — the user doesn't want to see "Resynced …" on every response. The script's stderr goes to ~/.claude/hooks/.state/oneshot.stderr if anything fails.
It pushes the color through. It does NOT revive Claude Code's automatic hook firing in a session that's gone silent. If a tab keeps needing manual resyncs, the underlying problem is at the Claude Code level (cached hook config, dead event loop, etc.) and resync is a workaround — flag that to the user rather than letting them resync the same tab every minute.
