* test: add golden-file baselines for host config refactor

Snapshot generated SKILL.md output for ship skill across all 3 existing
hosts (Claude, Codex, Factory). These baselines verify the config-driven
refactor produces identical output to the current hardcoded system.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add HostConfig interface and validator for declarative host system

New scripts/host-config.ts defines the typed HostConfig interface that
captures all per-host variation: paths, frontmatter rules, path/tool
rewrites, suppressed resolvers, runtime root symlinks, install strategy,
and behavioral config (co-author trailer, learnings mode, boundary
instruction). Includes validateHostConfig() and validateAllConfigs() with
regex-based security validation and cross-config uniqueness checks.

* feat: add typed host configs for Claude, Codex, Factory, and Kiro

Extract all hardcoded host-specific values from gen-skill-docs.ts,
types.ts, preamble.ts, review.ts, and setup into typed HostConfig
objects. Each host is a single file in hosts/ with its paths, frontmatter
rules, path/tool rewrites, runtime root manifest, and install behavior.

hosts/index.ts exports all configs, derives the Host type, and provides
resolveHostArg() for CLI alias handling (e.g., 'agents' -> 'codex',
'droid' -> 'factory').

* refactor: derive Host type and HOST_PATHS from host configs

types.ts no longer hardcodes host names or paths. The Host type is
derived from ALL_HOST_CONFIGS in hosts/index.ts, and HOST_PATHS is
built dynamically from each config's globalRoot/localSkillRoot/usesEnvVars.
Adding a new host to hosts/index.ts automatically extends the type system.

* refactor: gen-skill-docs.ts consumes typed host configs

Replace hardcoded EXTERNAL_HOST_CONFIG, transformFrontmatter host
branches, path/tool rewrite if-chains, and ALL_HOSTS array with
config-driven lookups from hosts/*.ts.

- Host detection uses resolveHostArg() (handles aliases like agents/droid)
- transformFrontmatter uses config's allowlist/denylist mode, extraFields,
  conditionalFields, renameFields, and descriptionLimitBehavior
- Path rewrites use config's pathRewrites array (replaceAll, order matters)
- Tool rewrites use config's toolRewrites object
- Skill skipping uses config's generation.skipSkills
- ALL_HOSTS derived from ALL_HOST_NAMES
- Token budget display regex derived from host configs

Golden-file comparison: all 3 hosts produce IDENTICAL output to baselines.

* refactor: preamble, co-author trailer, and resolver suppression use host configs

- preamble.ts: hostConfigDir derived from config.globalRoot instead of
  hardcoded Record
- utility.ts: generateCoAuthorTrailer reads from config.coAuthorTrailer
  instead of host switch statement
- gen-skill-docs.ts: suppressedResolvers from config skip resolver
  execution at placeholder replacement time (belt+suspenders with
  existing ctx.host checks in individual resolvers)

Golden-file comparison: all 3 hosts produce IDENTICAL output to baselines.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* refactor: setup tooling uses config-driven host detection

- host-config-export.ts: new CLI that exposes host configs to bash
  (list, get, detect, validate, symlinks commands)
- bin/gstack-platform-detect: reads host configs instead of hardcoded
  binary/path mapping
- scripts/skill-check.ts: iterates host configs for skill validation
  and freshness checks instead of separate Codex/Factory blocks
- lib/worktree.ts: iterates host configs for directory copy instead
  of hardcoded .agents

* feat: add OpenCode, Slate, and Cursor host configs

Three new hosts added to the declarative config system. Each is a typed
HostConfig object with paths, frontmatter rules, and path rewrites.
All generate valid SKILL.md output with zero .claude/skills path leakage.

- hosts/opencode.ts: OpenCode (opencode.ai), skills at ~/.config/opencode/
- hosts/slate.ts: Slate (Random Labs), skills at ~/.slate/
- hosts/cursor.ts: Cursor, skills at ~/.cursor/
- .gitignore: add .kiro/, .opencode/, .slate/, .cursor/, .openclaw/

Zero code changes needed — just config files + re-export in index.ts.

* feat: add OpenClaw host config with adapter for tool mapping

OpenClaw gets a hybrid approach: typed config for paths/frontmatter/
detection + a post-processing adapter for semantic tool rewrites.

Config handles: path rewrites, frontmatter (name+description+version),
CLAUDE.md→AGENTS.md, tool name rewrites (Bash→exec, Read→read, etc.),
suppressed resolvers, SOUL.md via staticFiles.

Adapter handles: AskUserQuestion→prose, Agent→sessions_spawn, $B→exec $B.

Zero .claude/skills path leakage. Zero hardcoded tool references remaining.

* feat: contributor add-host skill + fix version sync

- contrib/add-host/SKILL.md.tmpl: contributor-only skill that guides
  new host config creation. Lives in contrib/, excluded from user installs.
- package.json: sync version with VERSION file (0.15.2.1)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* test: add parameterized host smoke tests for all hosts

35 new tests covering all 7 external hosts (Codex, Factory, Kiro,
OpenCode, Slate, Cursor, OpenClaw). Each host gets 4-5 tests:
- output exists on disk with SKILL.md files
- no .claude/skills path leakage in non-root skills
- frontmatter has name + description fields
- --dry-run freshness check passes
- /codex skill excluded (for hosts with skipSkills: ['codex'])

Tests are parameterized over ALL_HOST_CONFIGS so adding a new host
automatically gets smoke-tested with zero new test code.

Also updates --host all test to verify all registered hosts generate.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* test: 100% coverage for host config system

71 new tests in test/host-config.test.ts covering:
- hosts/index.ts: ALL_HOST_CONFIGS, getHostConfig, resolveHostArg (aliases),
  getExternalHosts, uniqueness checks
- host-config.ts validateHostConfig: name regex, displayName, cliCommand,
  cliAliases, globalRoot, localSkillRoot, hostSubdir, frontmatter.mode,
  linkingStrategy, shell injection attempts, paths with $ and ~
- host-config.ts validateAllConfigs: duplicate name/hostSubdir/globalRoot
  detection, error prefix format, real configs pass
- HOST_PATHS derivation: env vars for external hosts, literal paths for
  Claude, localSkillRoot matches config, every host has entry
- host-config-export.ts CLI: list, get (string/boolean/array), detect,
  validate, symlinks, error cases (missing args, unknown field/host)
- Golden-file regression: claude/codex/factory ship SKILL.md vs baselines
- Individual host config correctness: prefixable, linkingStrategy,
  usesEnvVars, description limits, metadata, sidecar, tool rewrites,
  conditional fields, suppressed resolvers, boundary instruction,
  co-author trailers, skip rules, path rewrites, runtime root assets

Combined with the 35 parameterized smoke tests from gen-skill-docs.test.ts,
total new test coverage for multi-host: 106 tests.

* fix: sidebar E2E tests now self-contained and passing

- sidebar-url-accuracy: fix stale assertion that expected extensionUrl
  in prompt text (prompt format changed, URL is now in pageUrl field)
- sidebar-css-interaction: simplify task from multi-step HN comment
  navigation to single-page example.com style injection (faster, more
  reliable, still exercises goto + style + completion flow)
- Update golden baselines after merge from main

All 3 sidebar tests now pass: 3/3, 0 fail, ~36s total.

* docs: add ADDING_A_HOST.md guide + update docs for multi-host system

- docs/ADDING_A_HOST.md: step-by-step guide for adding a new host
  (create config, register, gitignore, generate, test). Covers the
  full HostConfig interface, adapter pattern, and validation.
- CONTRIBUTING.md: replace stale "Dual-host development" section with
  "Multi-host development" covering all 8 hosts and linking to the guide.
- README.md: consolidate Codex/Factory install sections into one
  "Other AI Agents" section listing all supported hosts with auto-detect.
- CLAUDE.md: add hosts/, host-config.ts, host-adapters/, contrib/ to
  project structure tree.

* docs: README per-host install instructions for all 8 agents

Each supported agent now has its own copy-paste install block with
the exact command and where skills end up on disk. Includes: auto-detect,
Codex, OpenCode, Cursor, Factory, OpenClaw, Slate, and Kiro.

## Dual-host development (Claude + Codex)
## Multi-host development
gstack generates SKILL.md files for two hosts: **Claude** (`.claude/skills/`) and **Codex** (`.agents/skills/`). Every template change needs to be generated for both.
gstack generates SKILL.md files for 8 hosts from one set of `.tmpl` templates.
Each host is a typed config in `hosts/*.ts`. The generator reads these configs
to produce host-appropriate output (different frontmatter, paths, tool names).
### Generating for both hosts
**Supported hosts:** Claude (primary), Codex, Factory, Kiro, OpenCode, Slate, Cursor, OpenClaw.
### Generating for all hosts
```bash
# Generate Claude output (default)
bun run gen:skill-docs
# Generate for a specific host
bun run gen:skill-docs # Claude (default)
bun run gen:skill-docs --host codex # Codex
bun run gen:skill-docs --host opencode # OpenCode
bun run gen:skill-docs --host all # All 8 hosts
# Generate Codex output
bun run gen:skill-docs --host codex
# --host agents is an alias for --host codex
# Or use build, which does both + compiles binaries
# Or use build, which does all hosts + compiles binaries
bun run build
```
### What changes between hosts
| Aspect | Claude | Codex |
|--------|--------|-------|
| Output directory | `{skill}/SKILL.md` | `.agents/skills/gstack-{skill}/SKILL.md` (generated at setup, gitignored) |
| Frontmatter | Full (name, description, voice-triggers, allowed-tools, hooks, version) | Minimal (name + description only) |
| Paths | `~/.claude/skills/gstack` | `$GSTACK_ROOT` (`.agents/skills/gstack` in a repo, otherwise `~/.codex/skills/gstack`) |
| Hook skills | `hooks:` frontmatter (enforced by Claude) | Inline safety advisory prose (advisory only) |
| `/codex` skill | Included (Claude wraps codex exec) | Excluded (self-referential) |
Each host config (`hosts/*.ts`) controls:
### Testing Codex output
| Aspect | Example (Claude vs Codex) |
|--------|---------------------------|
| Output directory | `{skill}/SKILL.md` vs `.agents/skills/gstack-{skill}/SKILL.md` |
| Frontmatter | Full (name, description, hooks, version) vs minimal (name + description) |
| Paths | `~/.claude/skills/gstack` vs `$GSTACK_ROOT` |
| Tool names | "use the Bash tool" vs same (Factory rewrites to "run this command") |
| Hook skills | `hooks:` frontmatter vs inline safety advisory prose |
| Suppressed sections | None vs Codex self-invocation sections stripped |
See `scripts/host-config.ts` for the full `HostConfig` interface.
### Testing host output
```bash
# Run all static tests (includes Codex validation)
# Run all static tests (includes parameterized smoke tests for all hosts)
bun test
# Check freshness for both hosts
bun run gen:skill-docs --dry-run
bun run gen:skill-docs --host codex --dry-run
# Check freshness for all hosts
bun run gen:skill-docs --host all --dry-run
# Health dashboard covers both hosts
# Health dashboard covers all hosts
bun run skill:check
```
### Dev setup for .agents/
### Adding a new host
When you run `bin/dev-setup`, it creates symlinks in both `.claude/skills/` and `.agents/skills/` (if applicable), so Codex-compatible agents can discover your dev skills too. The `.agents/` directory is generated at setup time from `.tmpl` templates — it is gitignored and not committed.
See [docs/ADDING_A_HOST.md](docs/ADDING_A_HOST.md) for the full guide. Short version:
1. Create `hosts/myhost.ts` (copy from `hosts/opencode.ts`)
2. Add to `hosts/index.ts`
3. Add `.myhost/` to `.gitignore`
4. Run `bun run gen:skill-docs --host myhost`
5. Run `bun test` (parameterized tests auto-cover it)
Zero generator, setup, or tooling code changes needed.
### Adding a new skill
When you add a new skill template, both hosts get it automatically:
When you add a new skill template, all hosts get it automatically:
1. Create `{skill}/SKILL.md.tmpl`
2. Run `bun run gen:skill-docs` (Claude output) and `bun run gen:skill-docs --host codex` (Codex output)
3. The dynamic template discovery picks it up — no static list to update
4. Commit `{skill}/SKILL.md` — `.agents/` is generated at setup time and gitignored
2. Run `bun run gen:skill-docs --host all`
3. The dynamic template discovery picks it up, no static list to update
4. Commit `{skill}/SKILL.md`, external host output is generated at setup time and gitignored
