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.

Sets one shared string as the tab title and the badge/watermark for THIS terminal session only, in iTerm2, WezTerm, or AI Power Term. Other tabs and panes are unaffected. Local-only: does NOT commit or push (session IDs change across terminal 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 in this order: $AI_POWER_TERM_SESSION_ID (AI Power Term), then $ITERM_SESSION_ID (iTerm2), then $WEZTERM_PANE (WezTerm). It writes the per-session conf plus a badge sidecar, then applies the label immediately:
rename action (the xterm.js frontend ignores OSC title escapes).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 plus badge sidecar and applies the label to the live tab in one shot. Don't commit or push: headsup-status.d/ is gitignored and per-session ephemeral.
/headsup-label again)."In iTerm2 the title may flicker if the user's profile doesn't have Allow Title Setting: false, because Claude Code's TUI re-asserts the title on each render. The 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 plus 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.~30 seconds. Free. No account. Every finding cites a rule and a line of evidence.
