A one-shot scoreboard showing ponytail's measured benchmark impact (less code, less cost, more speed) as plain ASCII bars, then points to /ponytail-debt and /ponytail-audit for this repo's real numbers. Complements the existing skills rather than duplicating them: debt harvests the ponytail: ledger, audit finds what's cuttable, gain shows the measured why-it-matters. No per-repo savings number is ever printed -- the unbuilt version was never written, so there is no real baseline to subtract from in a live repo. The bars carry the published benchmark medians (5 tasks, 3 models); per-repo figures come from debt's count. Ships every adapter the other commands ship: Claude commands/*.toml, OpenCode .opencode/command/*.md, OpenClaw skill (generated), Pi command registration. Help card, command enumeration, portability table, and README updated in the same change. Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

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. |
| pi | pi-extension/, skills/, hooks/ |
Package extension: injects the ruleset each turn through the shared instruction builder and registers the /ponytail commands. |
| 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 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. |
| GitHub Copilot CLI | .github/plugin/, AGENTS.md, .github/copilot-instructions.md, ~/.copilot/copilot-instructions.md |
Plugin-supported (copilot plugin marketplace add DietrichGebert/ponytail + copilot plugin install ponytail@ponytail). Fallback instruction mode remains: per-project from AGENTS.md or .github/copilot-instructions.md, or globally from ~/.copilot/copilot-instructions.md (instruction-tier, no /ponytail levels or hooks). |
| Antigravity | AGENTS.md |
Reads AGENTS.md at the repo root as always-on rules (like .cursorrules/CLAUDE.md); .agents/rules/ also works for workspace rules. Instruction-tier. |
| CodeWhale | AGENTS.md |
Reads AGENTS.md from the repo root as project instructions; also reads CLAUDE.md and .claude/instructions.md as fallbacks. Instruction-tier. |
| VS Code + Codex extension | AGENTS.md |
The Codex extension reads AGENTS.md (repo root, or ~/.codex/AGENTS.md globally). Instruction-tier; the full Codex plugin row above adds /ponytail levels and hooks. |
| 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.
