+## [0.13.9.0] - 2026-03-29 — Composable Skills
+
+Skills can now load other skills inline. Write `{{INVOKE_SKILL:office-hours}}` in a template and the generator emits the right "read file, skip preamble, follow instructions" prose automatically. Handles host-aware paths and customizable skip lists.
+
+### Added
+
+- **`{{INVOKE_SKILL:skill-name}}` resolver.** Composable skill loading as a first-class resolver. Emits host-aware prose that tells Claude or Codex to read another skill's SKILL.md and follow it inline, skipping preamble sections. Supports optional `skip=` parameter for additional sections to skip.
+- **Parameterized resolver support.** The placeholder regex now handles `{{NAME:arg1:arg2}}`, enabling resolvers that take arguments at generation time. Fully backward compatible with existing `{{NAME}}` patterns.
+- **`{{CHANGELOG_WORKFLOW}}` resolver.** Changelog generation logic extracted from /ship into a reusable resolver. Includes voice guidance ("lead with what the user can now do") inline.
+- **Frontmatter `name:` for skill registration.** Setup script and gen-skill-docs now read `name:` from SKILL.md frontmatter for symlink naming. Enables directory names that differ from invocation names (e.g., `run-tests/` directory registered as `/test`).
+- **Proactive skill routing.** Skills now ask once to add routing rules to your project's CLAUDE.md. This makes Claude invoke the right skill automatically instead of answering directly. Your choice is remembered in `~/.gstack/config.yaml`.
+- **Annotated config file.** `~/.gstack/config.yaml` now gets a documented header on first creation explaining every setting. Edit it anytime.
+
+### Changed
+
+- **BENEFITS_FROM now delegates to INVOKE_SKILL.** Eliminated duplicated skip-list logic. The prerequisite offer wrapper stays in BENEFITS_FROM, but the actual "read and follow" instructions come from INVOKE_SKILL.
+- **/plan-ceo-review mid-session fallback uses INVOKE_SKILL.** The "user can't articulate the problem, offer /office-hours" path now uses the composable resolver instead of inline prose.
+- **Stronger routing language.** office-hours, investigate, and ship descriptions now say "Proactively invoke" instead of "Proactively suggest" for more reliable automatic skill invocation.
+
+### Fixed
+
+- **Config grep anchored to line start.** Commented header lines no longer shadow real config values.
+
+## [0.13.8.0] - 2026-03-29 — Security Audit Round 2
+
+Browse output is now wrapped in trust boundary markers so agents can tell page content from tool output. Markers are escape-proof. The Chrome extension validates message senders. CDP binds to localhost only. Bun installs use checksum verification.
+
+### Fixed
+
+- **Trust boundary markers are escape-proof.** URLs sanitized (no newlines), marker strings escaped in content. A malicious page can't forge the END marker to break out of the untrusted block.
+
+### Added
+
+- **Content trust boundary markers.** Every browse command that returns page content (`text`, `html`, `links`, `forms`, `accessibility`, `console`, `dialog`, `snapshot`, `diff`, `resume`, `watch stop`) wraps output in `--- BEGIN/END UNTRUSTED EXTERNAL CONTENT ---` markers. Agents know what's page content vs tool output.
+- **Extension sender validation.** Chrome extension rejects messages from unknown senders and enforces a message type allowlist. Prevents cross-extension message spoofing.
+- **CDP localhost-only binding.** `bin/chrome-cdp` now passes `--remote-debugging-address=127.0.0.1` and `--remote-allow-origins` to prevent remote debugging exposure.
+- **Checksum-verified bun install.** The browse SKILL.md bootstrap now downloads the bun install script to a temp file and verifies SHA-256 before executing. No more piping curl to bash.
+
+### Removed
+
+- **Factory Droid support.** Removed `--host factory`, `.factory/` generated skills, Factory CI checks, and all Factory-specific code paths.
+
 ## [0.13.7.0] - 2026-03-29 — Community Wave
 
 Six community fixes with 16 new tests. Telemetry off now means off everywhere. Skills are findable by name. And changing your prefix setting actually works now.

+tool as your FIRST action. Do NOT answer directly, do NOT use other tools first.
+The skill has specialized workflows that produce better results than ad-hoc answers.

+- Product ideas, "is this worth building", brainstorming → invoke office-hours
+- Bugs, errors, "why is this broken", 500 errors → invoke investigate
+- Ship, deploy, push, create PR → invoke ship
+- QA, test the site, find bugs → invoke qa
+- Code review, check my diff → invoke review
+- Update docs after shipping → invoke document-release
+- Weekly retro → invoke retro
+- Design system, brand → invoke design-consultation

-3. **Read the full diff** to understand what each commit actually changed:
-   ```bash
-   git diff <base>...HEAD
-   ```
-
-4. **Group commits by theme** before writing anything. Common themes:
-   - New features / capabilities
-   - Performance improvements
-   - Bug fixes
-   - Dead code removal / cleanup
-   - Infrastructure / tooling / tests
-   - Refactoring
-
-5. **Write the CHANGELOG entry** covering ALL groups:
-   - If existing CHANGELOG entries on the branch already cover some commits, replace them with one unified entry for the new version
-   - Categorize changes into applicable sections:
-     - `### Added` — new features
-     - `### Changed` — changes to existing functionality
-     - `### Fixed` — bug fixes
-     - `### Removed` — removed features
-   - Write concise, descriptive bullet points
-   - Insert after the file header (line 5), dated today
-   - Format: `## [X.Y.Z.W] - YYYY-MM-DD`
-
-6. **Cross-check:** Compare your CHANGELOG entry against the commit list from step 2.
-   Every commit must map to at least one bullet point. If any commit is unrepresented,
-   add it now. If the branch has N commits spanning K themes, the CHANGELOG must
-   reflect all K themes.
-
-**Do NOT ask the user to describe changes.** Infer from the diff and commit history.
