maestro-token-efficiency

maestro-token-efficiency is a skill for Claude Code, Codex from mbanderas/maestro. It costs 29 tokens per session (235 once invoked), scanned A, original, MIT.

A set of working rules for reducing how much background text an AI coding agent needs while preserving its checks and verification.

In plain words
What is it for?
Use it when changing Maestro’s agent instructions, benchmark context, Codex guidance, or search and navigation practices.
Why use it?
It helps keep the agent focused, avoids loading unnecessary files, and prevents efficiency changes from weakening quality checks.

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

maestro-token-efficiency 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 4d 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.

What it actually says

Maestro Token Efficiency

Use this skill for Maestro repo changes that affect agent context, instruction loading, benchmark search hygiene, or Codex behavior.

  1. Read docs/agent-map.md first for navigation.
  2. Prefer benchmark summary files over raw streams unless doing forensic scoring. Use rg --no-ignore for raw stream audits.
  3. Preserve Maestro's quality bar: no weaker verification status, no hidden-oracle exposure, and no default behavior change without benchmark evidence.
  4. For Codex-specific behavior, check docs/codex.md and current official Codex docs before changing durable guidance.
  5. Keep always-loaded instruction files stable. Put volatile run notes, dated scratch state, machine-local paths, and benchmark deltas in summaries or checkpoints, not AGENTS.md/adapters.

Before completion after edits, run:

npm test
npm run lint
npm run bench-verify

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.
