Instructions file for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: reads .claude/ paths; mentions Claude Code; mentions OpenCode.

Runs only inside a plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else, and the catalogue could not identify which plugin ships it.

Getting it into your agent

There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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.

Security

Grade A, and why

ensemble 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 6d 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.

/ensemble:release              # Orchestrate release workflow
/ensemble:playwright-test      # Run E2E tests with Playwright
/ensemble:sessionlog           # Save structured session transcript
/ensemble:manager-dashboard    # Generate productivity metrics
/ensemble:sprint-status        # Current sprint status report

Essential Commands

npm test                    # Run all tests
npm run validate            # Validate marketplace + plugins
npm run generate            # Regenerate markdown from YAML
npm run generate:opencode   # Generate OpenCode-compatible artifacts from Ensemble plugins
npm run test:coverage       # Coverage reports

Key Paths

  • Plugins: packages/*/ (24 packages)
  • Agents: packages/*/agents/*.yaml (28 agents)
  • Commands: packages/*/commands/
  • Skills: packages/*/skills/
  • Schemas: schemas/{plugin,marketplace}-schema.json
  • OpenCode Output: dist/opencode/ (generated artifacts for OpenCode runtime)

OpenCode Support

Ensemble plugins can be translated for use with the OpenCode runtime via npm run generate:opencode. This generates OpenCode-compatible skills, commands, and config in dist/opencode/. Supports --dry-run, --verbose, --validate, and --force flags. See packages/opencode/ for the translation layer implementation.

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.
