fix: Codex compatibility — 1024-char cap, duplicate skills, repo-local installs, kiro support (v0.11.2.0) (#346)

* fix: cap gstack skill descriptions for codex (#251)

Compresses SKILL.md.tmpl root description to <1024 chars (Codex token limit).
Adds description-length validation test. Includes /autoplan in compressed
skill list (added since PR was branched).

* fix: skip sidecar dir in Codex skill linking (#269)

Adds guard to skip .agents/skills/gstack in link_codex_skill_dirs() —
it's a runtime asset sidecar, not a standalone skill. Prevents duplicate
skill discovery and symlink overwriting.

Fixes #261

* fix: generate .agents directory at setup time instead of shipping duplicates (#308)

Removes 14K+ lines of committed generated Codex skill files from git.
.agents/ is now gitignored and generated at setup time via
`bun run gen:skill-docs --host codex`. Updates CI workflow to validate
generation instead of checking committed file freshness.

* fix: avoid duplicate Codex skill discovery (#236)

Adds migrate_direct_codex_install() to move old direct installs from
~/.codex/skills/gstack to ~/.gstack/repos/gstack. Adds
create_codex_runtime_root() to expose only runtime assets (bin/, browse/,
review files) via symlinks instead of symlinking the entire repo.

Fixes #235

* feat: support repo-local Codex installs (#317)

Changes gen-skill-docs.ts to use dynamic $GSTACK_ROOT/$GSTACK_BIN/$GSTACK_BROWSE
variables in generated Codex preambles instead of hardcoded ~/.codex/ paths.
Renames GSTACK_DIR → SOURCE_GSTACK_DIR/INSTALL_GSTACK_DIR throughout setup for
clarity. Supports both global (~/.codex/skills/) and repo-local (.agents/skills/)
Codex installs.

* feat: add --host kiro support to setup script (#309)

Adds Kiro CLI as a supported agent platform. Setup detects kiro-cli,
copies+sed-rewrites SKILL.md paths from Codex/Claude to Kiro format,
and symlinks runtime assets (bin/, browse/).

* test: add sidecar skip, GSTACK_ROOT, and kiro coverage (T1-T3)

Adds 3 tests identified during CEO/Eng review:
- T1: link_codex_skill_dirs() contains sidecar skip guard
- T2: generated Codex preambles use dynamic $GSTACK_ROOT paths
- T3: setup supports --host kiro with INSTALL_KIRO and sed rewrites

Also fixes existing test to expect kiro in --host case statement.

* fix: review fixes — ETHOS.md, runtime root, repo-local guard, kiro assets, upgrade paths

Paranoid 4-pass review found 7 issues, all fixed:
- Add ETHOS.md to create_codex_runtime_root
- Clean old real dirs (not just symlinks) on upgrade
- Skip runtime root for repo-local installs (prevent self-referential symlinks)
- Add review/, ETHOS.md, gstack-upgrade/ to Kiro install
- Update gstack-upgrade to detect ~/.gstack/repos/ and .agents/skills/
- Guard --host without value from silent exit
- Fix Kiro sed patterns + timeout instruction in gen-skill-docs.ts

 # Changelog
 
+## [0.11.2.0] - 2026-03-22 — Codex Just Works
+
+### Fixed
+
+- **Codex no longer shows "exceeds maximum length of 1024 characters" on startup.** Skill descriptions compressed from ~1,200 words to ~280 words — well under the limit. Every skill now has a test enforcing the cap.
+- **No more duplicate skill discovery.** Codex used to find both source SKILL.md files and generated Codex skills, showing every skill twice. Setup now creates a minimal runtime root at `~/.codex/skills/gstack` with only the assets Codex needs — no source files exposed.
+- **Old direct installs auto-migrate.** If you previously cloned gstack into `~/.codex/skills/gstack`, setup detects this and moves it to `~/.gstack/repos/gstack` so skills aren't discovered from the source checkout.
+- **Sidecar directory no longer linked as a skill.** The `.agents/skills/gstack` runtime asset directory was incorrectly symlinked alongside real skills — now skipped.
+
+### Added
+
+- **Repo-local Codex installs.** Clone gstack into `.agents/skills/gstack` inside any repo and run `./setup --host codex` — skills install next to the checkout, no global `~/.codex/` needed. Generated preambles auto-detect whether to use repo-local or global paths at runtime.
+- **Kiro CLI support.** `./setup --host kiro` installs skills for the Kiro agent platform, rewriting paths and symlinking runtime assets. Auto-detected by `--host auto` if `kiro-cli` is installed.
+- **`.agents/` is now gitignored.** Generated Codex skill files are no longer committed — they're created at setup time from templates. Removes 14,000+ lines of generated output from the repo.
+
+### Changed
+
+- **`GSTACK_DIR` renamed to `SOURCE_GSTACK_DIR` / `INSTALL_GSTACK_DIR`** throughout the setup script for clarity about which path points to the source repo vs the install location.
+- **CI validates Codex generation succeeds** instead of checking committed file freshness (since `.agents/` is no longer committed).
+
 ## [0.11.1.1] - 2026-03-22 — Plan Files Always Show Review Status
