headsup-label-0e2362 — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited headsup-label-0e2362 (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.

First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
Sets one shared string as both the iTerm2 badge (top-right watermark) and the window/tab title for THIS iTerm2 session only. Other tabs / panes are unaffected. Local-only — does NOT commit/push (session IDs change across iTerm2 restarts, so committing would just accumulate dead files).
All of the logic lives in one permanent script, ~/.claude/hooks/headsup-set-label.sh. It resolves the session from $ITERM_SESSION_ID (present in the Bash tool's environment), writes the per-session conf + badge sidecar, and applies the badge + title immediately — writing the OSC escapes to stdout when it IS the tty (Quick Action path), or walking up the process tree to the real tty when run from inside a Claude Code session.
Because every invocation starts with the same path, a single permission allowlist rule covers it and the user is never prompted:
Bash(~/.claude/hooks/headsup-set-label.sh:*)(setup.sh adds this rule automatically. If the user reports a permission prompt, check it exists in ~/.claude/settings.json under permissions.allow.)
headsup_badge_text() and headsup_title_text() definitions that return the chosen label.headsup-status.d/ is gitignored; nothing committed.Prompt-first design. Do NOT run any Bash commands before you have the label. Reading the current label or looking up the session key first would trigger activity before the user has even been asked what they want. If the user wants to know the current label they'll ask.
/headsup-label deploy debugging), use that argument verbatim as the label. Skip to step 2.AskUserQuestion or plain text — but before any tool calls.~/.claude/hooks/, not the expanded absolute path, so the permission allowlist prefix matches and the user isn't prompted): ~/.claude/hooks/headsup-set-label.sh '<user-supplied-label>'Single-quote the label; escape any literal ' inside as '\''. The script writes the conf + badge sidecar and applies the badge + title to the live tab in one shot. Don't commit / push — headsup-status.d/ is gitignored and per-session ephemeral.
/headsup-label again)."The title may flicker if the user's iTerm2 profile doesn't have Allow Title Setting: false — Claude Code's TUI re-asserts the title on each render. Badge is stable regardless. Mention only if it actually misbehaves.
If the user wants to remove the per-session override and revert to the global default (Claude · <project> etc.):
~/.claude/hooks/headsup-set-label.sh --clearThis deletes the per-session conf + badge sidecar, recomputes the default badge/title from the global conf, and re-applies them to the live tab.
/headsup-colors is the global-and-committed counterpart.ITERM_SESSION_ID is empty, the design fails — the script prints an error and exits cleanly.
