Garry Tan 8500136d15 feat: remove trigger guard + proactive opt-out prompt (#457)
* fix: telemetry source tagging + duration guards

Add --source, --error-message, --failed-step flags to gstack-telemetry-log.
Source tagging (live vs test via GSTACK_TELEMETRY_SOURCE env) prevents E2E
tests from polluting production data. Duration guards cap unreasonable
values (>24h or negative → null).

Partial cherry-pick from garrytan/community-mode — non-breaking parts only.
Skips install_fingerprint rename (needs schema migration).

* feat: remove trigger guard + proactive opt-out prompt

Remove "MANUAL TRIGGER ONLY" injection from all skill descriptions. This
frees 59 chars per skill from the 1024-char Codex description budget and
lets skills auto-fire based on semantic matching.

Merge auto-fire control into the existing `proactive` setting — when false,
Claude won't auto-invoke skills or suggest them. Users are prompted once
about this preference (chains after the telemetry prompt, fires on second
skill run).

Also trims the root gstack description by removing the skill catalog
(already in the body), saving ~500 chars.

guard 0.1.0 Full safety mode: destructive command warnings + directory-scoped edits. Combines /careful (warns before rm -rf, DROP TABLE, force-push, etc.) with /freeze (blocks edits outside a specified directory). Use for maximum safety when touching prod or debugging live systems. Use when asked to "guard mode", "full safety", "lock it down", or "maximum safety".

/guard — Full Safety Mode

Activates both destructive command warnings and directory-scoped edit restrictions. This is the combination of /careful + /freeze in a single command.

Dependency note: This skill references hook scripts from the sibling /careful and /freeze skill directories. Both must be installed (they are installed together by the gstack setup script).

mkdir -p ~/.gstack/analytics
echo '{"skill":"guard","ts":"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'","repo":"'$(basename "$(git rev-parse --show-toplevel 2>/dev/null)" 2>/dev/null || echo "unknown")'"}'  >> ~/.gstack/analytics/skill-usage.jsonl 2>/dev/null || true

Setup

Ask the user which directory to restrict edits to. Use AskUserQuestion:

  • Question: "Guard mode: which directory should edits be restricted to? Destructive command warnings are always on. Files outside the chosen path will be blocked from editing."
  • Text input (not multiple choice) — the user types a path.

Once the user provides a directory path:

  1. Resolve it to an absolute path:
FREEZE_DIR=$(cd "<user-provided-path>" 2>/dev/null && pwd)
echo "$FREEZE_DIR"
  1. Ensure trailing slash and save to the freeze state file:
FREEZE_DIR="${FREEZE_DIR%/}/"
STATE_DIR="${CLAUDE_PLUGIN_DATA:-$HOME/.gstack}"
mkdir -p "$STATE_DIR"
echo "$FREEZE_DIR" > "$STATE_DIR/freeze-dir.txt"
echo "Freeze boundary set: $FREEZE_DIR"

Tell the user:

  • "Guard mode active. Two protections are now running:"
  • "1. Destructive command warnings — rm -rf, DROP TABLE, force-push, etc. will warn before executing (you can override)"
  • "2. Edit boundary — file edits restricted to <path>/. Edits outside this directory are blocked."
  • "To remove the edit boundary, run /unfreeze. To deactivate everything, end the session."

What's protected

See /careful for the full list of destructive command patterns and safe exceptions. See /freeze for how edit boundary enforcement works.
