Danijel Martinek 90fc2853f2 feat(work): add ISO timestamps + auto-bump on staged work-doc changes 
- New scripts/work/bump-updated-timestamps.mjs stamps the `updated:`
  frontmatter field to the current ISO 8601 UTC timestamp on every
  staged docs/work/**/*.md file. Idempotent; adds the field after
  `created:` if missing.
- .husky/pre-commit invokes the bump script as step 2 (before
  rebuild-state) so _state.json sees the fresh timestamp.
- Backfill all existing work docs (4 PRDs + 3 epics + 21 stories):
    * created: promoted from \`YYYY-MM-DD\` -> ISO timestamp using
      git log --diff-filter=A on each file (first-commit date for
      stories that had no \`created:\` line, midnight UTC for PRDs
      and epics that had date-only created).
    * updated: added from \`git log -1 --format=%aI\` on each file
      (last-commit timestamp); will be re-stamped to "now" by the
      pre-commit hook on this commit.

Stories that had no \`created:\` line now get one.

Goal

Write .claude/hooks/library-policy-nudge.sh — a single hook script that dispatches on tool_use_type to handle both PreToolUse (Bash invocations matching pnpm add / pnpm i <pkg>) and PostToolUse (Edit/Write on any **/package.json). On match, emit a non-blocking system-reminder pointing the agent at the evaluate-library skill with the exact invocation pattern. Register the hook in .claude/settings.json following the same pattern as generator-first-nudge.sh.

Why

Agents (and developers) running pnpm add by reflex bypass the policy before the pre-commit gate fires. The PreToolUse hook injects the skill reminder before the install runs — the cheapest possible intervention point. The PostToolUse hook catches the rarer case where an agent edits package.json directly without running the install command.

Done when

  • .claude/hooks/library-policy-nudge.sh exists, is executable, dispatches on CLAUDE_TOOL_USE_TYPE (or equivalent hook env var), and emits the reminder to stdout when a pnpm add/pnpm i <pkg> bash command is detected or when an Edit/Write tool targets a path matching **/package.json.
  • The hook is registered in .claude/settings.json (or .claude/settings.local.json if per-repo convention) under both PreToolUse and PostToolUse event types, matching the registration pattern of generator-first-nudge.sh.
  • The reminder text includes the literal string /evaluate-library and the argument template <name> --tier <feature|core|app> --target <package-path> so the agent sees the exact invocation.
  • Bash smoke tests (same style as any existing hook tests): pipe a mocked Claude hook payload { "tool_input": { "command": "pnpm add foo" } } into the script and assert stdout contains the skill-reminder marker; pipe a payload for pnpm add -D foo (devdep) and assert no reminder emitted; pipe an Edit payload on src/feature.manifest.ts and assert no reminder emitted.
  • pnpm lint && pnpm fallow:audit pass.

In scope

  • .claude/hooks/library-policy-nudge.sh — the hook script.
  • .claude/settings.json (or equivalent) — hook registration lines.
  • Bash smoke tests for the hook script.

Out of scope

  • Hook auto-deny or blocking behavior — the hook is advisory only (non-blocking system-reminder).
  • Hooks for npm install / yarn add — the repo is pnpm-only.
  • Integration with the skill implementation (Story 04) — the hook emits a text reminder; the skill is a separate file.

Tasks

  • Investigate how generator-first-nudge.sh is registered (read .claude/settings.json and the existing hook script) to confirm the env-var names, payload shape, and registration keys; then write .claude/hooks/library-policy-nudge.sh + register it in the settings file + write bash smoke tests covering pnpm add <pkg> (reminder), pnpm add -D <pkg> (no reminder), Edit on non-package.json (no reminder), Edit on package.json (reminder); all gates pass on this single commit.
