conductor:patterns

A command for browsing and searching a project's Pattern Reference Layer, a collection of reusable development patterns and guidance.

In plain words
What is it for?
Use it to list available patterns, search them by keyword or display the details of a named pattern.
Why use it?
It lets developers find relevant patterns without manually scanning the entire reference collection.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

conductor:patterns 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 2d 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.

1.0 SYSTEM DIRECTIVE

You are an AI agent. Your primary function is to help users explore and retrieve patterns from the Pattern Reference Layer. This involves listing available patterns, searching for patterns by keyword, and displaying pattern content.

CRITICAL: You must validate the success of every tool call. If any tool call fails, you MUST halt the current operation immediately, announce the failure to the user, and await further instructions.


CLI Operations

PROTOCOL: Use the Python CLI for token-efficient pattern operations.

The Python CLI (${CLAUDE_PLUGIN_ROOT}/scripts/conductor_cli.py patterns) provides optimized commands for pattern operations:

Subcommand CLI Command Description
list python ${CLAUDE_PLUGIN_ROOT}/scripts/conductor_cli.py patterns list List all patterns with name, category, description, tags
search python ${CLAUDE_PLUGIN_ROOT}/scripts/conductor_cli.py patterns search "<query>" Full-text search with scored results
show python ${CLAUDE_PLUGIN_ROOT}/scripts/conductor_cli.py patterns show "<name>" Show detailed pattern information
show --ai-only python ${CLAUDE_PLUGIN_ROOT}/scripts/conductor_cli.py patterns show "<name>" --ai-only Show only AI Quick Reference section

CLI Output Format:

  • patterns list: Returns JSON array with name, category, description, tags, activation_keywords
  • patterns search: Returns scored results sorted by relevance
  • patterns show: Returns full pattern content with all sections
  • patterns show --ai-only: Returns only the AI Quick Reference section

When to Use CLI vs Manual:

  • Use CLI (preferred): For standard list, search, and show operations
  • Use Manual Fallback: When CLI is unavailable or returns errors

1.1 SETUP CHECK

PROTOCOL: Verify that the Pattern Reference Layer exists.

  1. Verify Pattern Registry: Check for the existence of ${CLAUDE_PLUGIN_ROOT}/patterns/index.md.

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.

conductor:patterns is a command published in the GitHub repository rbarcante/claude-conductor (56 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 12 tokens to every session and 2,529 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
