* feat: add Gemini CLI support Add a thin Gemini CLI extension adapter (closes #22). The manifest points contextFileName at the existing AGENTS.md for always-on rules and reuses the repo's commands/*.toml (/ponytail, /ponytail-review) and skills/, which Gemini CLI auto-discovers — no rule text is duplicated. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * test: read manifest inside cases for a clean RED The manifest was parsed at module scope, so reverting the adapter crashed the whole test file at load (ENOENT) and collapsed all four cases into one unreadable failure. Read it inside each case via a helper that asserts existence first, so a missing or malformed manifest surfaces as clear per-case assertion failures instead of a stack trace.

Agent Portability
Ponytail is an agent-portable skill distribution. The skills in skills/ hold
the core behavior; host-specific files are adapters that make that behavior easy
to load in a given agent.
Supported Adapters
| Host | Files | Notes |
|---|---|---|
| Claude Code | .claude-plugin/, commands/, hooks/ |
Full plugin install with session activation, mode tracking, commands, and statusline support. |
| Codex | .codex-plugin/plugin.json, hooks/hooks.json, hooks/, skills/ |
Plugin install with the same skills plus lifecycle hooks for activation and mode tracking. |
| OpenCode | .opencode/plugins/ponytail.mjs, .opencode/command/, hooks/, skills/ |
Server plugin injects the ruleset each turn via experimental.chat.system.transform and persists /ponytail switches; reuses the shared instruction builder. |
| Gemini CLI | gemini-extension.json, AGENTS.md, commands/, skills/ |
Extension manifest points contextFileName at AGENTS.md for always-on rules, and reuses the existing commands/*.toml (/ponytail, /ponytail-review) and skills/, which Gemini CLI auto-discovers. |
| Cursor | .cursor/rules/ponytail.mdc |
Always-on project rule. |
| Windsurf | .windsurf/rules/ponytail.md |
Project rule. |
| Cline | .clinerules/ponytail.md |
Project rule. |
| GitHub Copilot | .github/copilot-instructions.md |
Repository instruction file. |
| Kiro | .kiro/steering/ponytail.md |
Steering rule; copy globally or into a project. |
| Generic agents | AGENTS.md or skills/*/SKILL.md |
Copy the compact rule file or load the skill files directly. |
Adapter Rule
Keep adapters thin. When a host supports skills or hooks, point it at the
existing skills/ and hooks/ files. When a host only supports project
instructions, keep its copied rule text aligned with AGENTS.md.
