What is wild-horses CLAUDE.md?

A set of project instructions for maintaining Wild Horses, a Claude Code plugin marketplace that catalogs and distributes coding-agent plugins.

Use it when adding or changing marketplace entries, plugins, commands, or skills, including the matching Cursor marketplace files.

It gives agents the repository structure, required files, validation rules, and links to the relevant Claude Code documentation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.03407	$0.03407
Opus 5	$0.01703	$0.01703
Sonnet 5	$0.00681	$0.00681
Haiku 4.5	$0.00341	$0.00341

Security

Grade A, and why

wild-horses CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Wild Horses - Claude Code Plugin Marketplace

Project Structure

This is a Claude Code plugin marketplace.

.claude-plugin/marketplace.json    -- marketplace catalog (points to plugins)
plugins/harness/                   -- plugin root (commands-based)
  .claude-plugin/plugin.json       -- plugin manifest
  commands/feedback-blockers.md    -- /harness:feedback-blockers
  commands/reasoning-gaps.md       -- /harness:reasoning-gaps
plugins/marketplace/               -- plugin root (skills-based)
  .claude-plugin/plugin.json       -- plugin manifest
  skills/create/SKILL.md           -- /create (marketplace scaffolding)

Rules

Marketplace Structure

marketplace.json goes in .claude-plugin/ at the repo root. Do NOT add "$schema" — the validator rejects unrecognized keys.
Cursor parity: also ship .cursor-plugin/marketplace.json at the repo root and .cursor-plugin/plugin.json per plugin. Claude hooks stay in hooks/hooks.json (PascalCase, nested); Cursor hooks go in hooks/cursor-hooks.json (camelCase, flat) and are referenced from the Cursor manifest via "hooks": "hooks/cursor-hooks.json". Hook scripts that emit permission decisions must support both Claude (hookSpecificOutput) and Cursor (permission) formats — branch on hook_event_name from stdin.
Each plugin lives in its own directory under plugins/. The plugin's .claude-plugin/plugin.json goes inside that directory, NOT at the repo root.
Skills, agents, commands, and hooks go at the plugin root level, NOT inside .claude-plugin/.
Validate with: claude plugin validate . or /plugin validate .

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
