feat: Factory Droid compatibility — works across Claude Code, Codex, and Factory (v0.13.5.0) (#621) * refactor: extract processExternalHost() shared helper for multi-host generation Refactor the Codex-specific output routing block in gen-skill-docs.ts into a shared processExternalHost() function. Both Codex and future external hosts (Factory Droid) will use this helper for output routing, symlink loop detection, frontmatter transformation, path rewrites, and metadata generation. - Rename codexSkillName() to externalSkillName() everywhere - Extract ExternalHostConfig interface with per-host settings - Codex output is byte-identical (verified via --dry-run) - Skip /codex skill for all non-Claude hosts (not just codex) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: add Factory Droid host type, preamble, and co-author trailer - Add 'factory' to Host union type with .factory/skills/gstack paths - Extend preamble runtime root detection for Factory ($HOME/.factory/) - Add GSTACK_DESIGN env var to preamble (was missing for Codex too) - Add Factory Droid co-author trailer for git commits Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: Factory Droid generation, --host all, and host-aware frontmatter - Add --host factory (alias: --host droid) to gen-skill-docs - Add --host all: generates for claude, codex, and factory in one invocation with fault-tolerant per-host error handling (only fails if claude fails) - Factory frontmatter: name + description + user-invocable: true - Factory sensitive skills: disable-model-invocation: true (from sensitive: field) - Claude: strips sensitive: field from output (only Factory uses it) - Factory tool name translation: Claude tool names → generic phrasing - Replace chained gen:skill-docs calls with --host all in package.json build Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: sensitive frontmatter for Factory Droid auto-invocation safety Add sensitive: true to 6 skill templates with side effects that Factory Droids shouldn't auto-invoke (ship, land-and-deploy, guard, careful, freeze, unfreeze). The field is: - Factory: emitted as disable-model-invocation: true - Claude/Codex: stripped from output by transformFrontmatter() Also fix Claude host path: call transformFrontmatter() for Claude to strip the sensitive: field from Claude output.

Useful for debugging multi-host setups. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: Factory Droid support in setup script - Add factory to --host values (auto-detected via command -v droid) - Add .factory/ skill doc generation step alongside .agents/ - Add create_factory_runtime_root() and link_factory_skill_dirs() helpers mirroring the Codex equivalents - Factory install section creates ~/.factory/skills/ with symlinks Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: Factory Droid awareness in skill-check and uninstall - skill-check.ts: add Factory skills validation and freshness check - gstack-uninstall: add Factory artifact cleanup (~/.factory/skills/gstack* and per-project .factory/ sidecar) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * test: Factory Droid generation + --host all test suites Add 13 new tests: - Factory output paths, frontmatter (user-invocable, disable-model-invocation) - Sensitive vs non-sensitive skill classification - Path rewrites (no .claude/skills/ in Factory output) - /codex skill exclusion, openai.yaml absence - Factory keeps Codex integration blocks (for second opinions) - --host droid alias, --dry-run freshness, preamble paths - --host all generates for all 3 hosts - Setup script host validation updated for factory Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: Factory Droid install instructions + CI freshness check - README: add Factory Droid section with install instructions and restart note (Factory requires restart to rescan skills) - CI: add Factory skill doc freshness verification to skill-docs.yml Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: generated Factory Droid skill output (.factory/skills/) 29 skills generated for Factory Droid with: - user-invocable: true on all skills - disable-model-invocation: true on 6 sensitive skills - .factory/skills/ paths (no .claude/skills/ references) - $GSTACK_ROOT env vars for runtime root detection - Tool name translation (Claude tool names → generic phrasing) Committed to git for CI freshness checks and direct consumption.
