@@ -10,6 +10,45 @@ When both `/review` (Claude) and `/codex review` have run, you get a cross-model
 
 **Integrated everywhere.** After `/review` finishes, it offers a Codex second opinion. During `/ship`, you can run Codex review as an optional gate before pushing. In `/plan-eng-review`, Codex can independently critique your plan before the engineering review begins. All Codex results show up in the Review Readiness Dashboard.
 
+## [0.7.4] - 2026-03-18
+
+### Changed
+
+- **`/qa` and `/design-review` now ask what to do with uncommitted changes** instead of refusing to start. When your working tree is dirty, you get an interactive prompt with three options: commit your changes, stash them, or abort. No more cryptic "ERROR: Working tree is dirty" followed by a wall of text.
+
+## [0.7.3] - 2026-03-18
+
+### Added
+
+- **Safety guardrails you can turn on with one command.** Say "be careful" or "safety mode" and `/careful` will warn you before any destructive command — `rm -rf`, `DROP TABLE`, force-push, `kubectl delete`, and more. You can override every warning. Common build artifact cleanups (`rm -rf node_modules`, `dist`, `.next`) are whitelisted.
+- **Lock edits to one folder with `/freeze`.** Debugging something and don't want Claude to "fix" unrelated code? `/freeze` blocks all file edits outside a directory you choose. Hard block, not just a warning. Run `/unfreeze` to remove the restriction without ending your session.
+- **`/guard` activates both at once.** One command for maximum safety when touching prod or live systems — destructive command warnings plus directory-scoped edit restrictions.
+- **`/debug` now auto-freezes edits to the module being debugged.** After forming a root cause hypothesis, `/debug` locks edits to the narrowest affected directory. No more accidental "fixes" to unrelated code during debugging.
+- **You can now see which skills you use and how often.** Every skill invocation is logged locally to `~/.gstack/analytics/skill-usage.jsonl`. Run `bun run analytics` to see your top skills, per-repo breakdown, and how often safety hooks actually catch something. Data stays on your machine.
+- **Weekly retros now include skill usage.** `/retro` shows which skills you used during the retro window alongside your usual commit analysis and metrics.
+
+## [0.7.2] - 2026-03-18
+
+### Fixed
+
+- `/retro` date ranges now align to midnight instead of the current time. Running `/retro` at 9pm no longer silently drops the morning of the start date — you get full calendar days.
+- `/retro` timestamps now use your local timezone instead of hardcoded Pacific time. Users outside the US-West coast get correct local hours in histograms, session detection, and streak tracking.
+
+## [0.7.1] - 2026-03-19
+
+### Added
+
+- **gstack now suggests skills at natural moments.** You don't need to know slash commands — just talk about what you're doing. Brainstorming an idea? gstack suggests `/office-hours`. Something's broken? It suggests `/debug`. Ready to deploy? It suggests `/ship`. Every workflow skill now has proactive triggers that fire when the moment is right.
+- **Lifecycle map.** gstack's root skill description now includes a developer workflow guide mapping 12 stages (brainstorm → plan → review → code → debug → test → ship → docs → retro) to the right skill. Claude sees this in every session.
+- **Opt-out with natural language.** If proactive suggestions feel too aggressive, just say "stop suggesting things" — gstack remembers across sessions. Say "be proactive again" to re-enable.
+- **11 journey-stage E2E tests.** Each test simulates a real moment in the developer lifecycle with realistic project context (plan.md, error logs, git history, code) and verifies the right skill fires from natural language alone. 11/11 pass.
+- **Trigger phrase validation.** Static tests verify every workflow skill has "Use when" and "Proactively suggest" phrases — catches regressions for free.
+
+### Fixed
+
+- `/debug` and `/office-hours` were completely invisible to natural language — no trigger phrases at all. Now both have full reactive + proactive triggers.

+### On-demand hook skills (/careful, /freeze, /guard) — SHIPPED
 
-**What:** Three new skills that use Claude Code's session-scoped PreToolUse hooks to add safety guardrails on demand.
+~~**What:** Three new skills that use Claude Code's session-scoped PreToolUse hooks to add safety guardrails on demand.~~
 
-**Why:** Anthropic's internal skill best practices recommend on-demand hooks for safety. Claude Code already handles destructive command permissions, but these add an explicit opt-in layer for high-risk sessions (touching prod, debugging live systems).
+Shipped as `/careful`, `/freeze`, `/guard`, and `/unfreeze` in v0.6.5. Includes hook fire-rate telemetry (pattern name only, no command content) and inline skill activation telemetry.
 
-**Skills:**
-- `/careful` — PreToolUse hook on Bash tool. Warns (not blocks) before destructive commands: `rm -rf`, `DROP TABLE`, `git push --force`, `git reset --hard`, `kubectl delete`, `docker system prune`. Uses `permissionDecision: "ask"` so user can override.
-- `/freeze` — PreToolUse hook on Edit/Write tools. Restricts file edits to a user-specified directory. Great for debugging without accidentally "fixing" unrelated code.
-- `/guard` — meta-skill composing `/careful` + `/freeze` into one command.
+### Skill usage telemetry — SHIPPED
 
-**Implementation notes:** Use `${CLAUDE_SKILL_DIR}` (not `${SKILL_DIR}`) for script paths in hook commands. Pure bash JSON parsing (no jq dependency). Freeze dir storage: `${CLAUDE_PLUGIN_DATA}/freeze-dir.txt` with `~/.gstack/freeze-dir.txt` fallback. Ensure trailing `/` on freeze dir paths to prevent `/src` matching `/src-old`.
+~~**What:** Track which skills get invoked, how often, from which repo.~~
 
-**Effort:** M (human) / S (CC)
+Shipped in v0.6.5. TemplateContext in gen-skill-docs.ts bakes skill name into preamble telemetry line. Analytics CLI (`bun run analytics`) for querying. /retro integration shows skills-used-this-week.
+
+### /debug scoped debugging enhancements (gated on telemetry)
+
+**What:** Six enhancements to /debug auto-freeze, contingent on telemetry showing the freeze hook actually fires in real debugging sessions.
+
+**Why:** /debug v0.7.1 auto-freezes edits to the module being debugged. If telemetry shows the hook fires often, these enhancements make the experience smarter. If it never fires, the problem wasn't real and these aren't worth building.
+
+**Context:** All items are prose additions to `debug/SKILL.md.tmpl`. No new scripts.
+
+**Items:**
+1. Stack trace auto-detection for freeze directory (parse deepest app frame)
+2. Freeze boundary widening (ask to widen instead of hard-block when hitting boundary)
+3. Post-fix auto-unfreeze + full test suite run
+4. Debug instrumentation cleanup (tag with DEBUG-TEMP, remove before commit)
+5. Debug session persistence (~/.gstack/debug-sessions/ — save investigation for reuse)
+6. Investigation timeline in debug report (hypothesis log with timing)
+
+**Effort:** M (all 6 combined)
 **Priority:** P3
-**Depends on:** None

-### Skill usage telemetry
-
-**What:** Track which skills get invoked, how often, from which repo.
-
-**Why:** Enables finding undertriggering skills and measuring adoption. Anthropic uses a PreToolUse hook for this; simpler approach is appending JSONL from the preamble.
-
-**Context:** Add to `generatePreamble()` in `scripts/gen-skill-docs.ts`. Append to `~/.gstack/analytics/skill-usage.jsonl` with skill name, timestamp, and repo name. `mkdir -p` ensures the directory exists.

+
+After forming your root cause hypothesis, lock edits to the affected module to prevent scope creep.
+
+```bash
+[ -x "${CLAUDE_SKILL_DIR}/../freeze/bin/check-freeze.sh" ] && echo "FREEZE_AVAILABLE" || echo "FREEZE_UNAVAILABLE"
+```
+
+**If FREEZE_AVAILABLE:** Identify the narrowest directory containing the affected files. Write it to the freeze state file:
+
+```bash
+STATE_DIR="${CLAUDE_PLUGIN_DATA:-$HOME/.gstack}"
+mkdir -p "$STATE_DIR"
+echo "<detected-directory>/" > "$STATE_DIR/freeze-dir.txt"
+echo "Debug scope locked to: <detected-directory>/"
+```
+
+Substitute `<detected-directory>` with the actual directory path (e.g., `src/auth/`). Tell the user: "Edits restricted to `<dir>/` for this debug session. This prevents changes to unrelated code. Run `/unfreeze` to remove the restriction."
+
+If the bug spans the entire repo or the scope is genuinely unclear, skip the lock and note why.

+```
+
+## Setup
+
+Ask the user which directory to restrict edits to. Use AskUserQuestion:
+
+- Question: "Which directory should I restrict edits to? Files outside this 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:
+```bash
+FREEZE_DIR=$(cd "<user-provided-path>" 2>/dev/null && pwd)
+echo "$FREEZE_DIR"
+```
+
+2. Ensure trailing slash and save to the freeze state file:
+```bash
+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: "Edits are now restricted to `<path>/`. Any Edit or Write
+outside this directory will be blocked. To change the boundary, run `/freeze`
+again. To remove it, run `/unfreeze` or end the session."
+
+## How it works
+
+The hook reads `file_path` from the Edit/Write tool input JSON, then checks
+whether the path starts with the freeze directory. If not, it returns
+`permissionDecision: "deny"` to block the operation.
+
+The freeze boundary persists for the session via the state file. The hook
+script reads it on every Edit/Write invocation.
+
+## Notes
+
+- The trailing `/` on the freeze directory prevents `/src` from matching `/src-old`
+- Freeze applies to Edit and Write tools only — Read, Bash, Glob, Grep are unaffected
+- This prevents accidental edits, not a security boundary — Bash commands like `sed` can still modify files outside the boundary
+- To deactivate, run `/unfreeze` or end the conversation

+
+## 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:
+```bash
+FREEZE_DIR=$(cd "<user-provided-path>" 2>/dev/null && pwd)
+echo "$FREEZE_DIR"
+```
+
+2. Ensure trailing slash and save to the freeze state file:
+```bash
+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.
