maestro AGENTS.md

Instructions for Maestro, an optional discipline layer for coordinating AI coding agents. It defines quality checks, a decision checkpoint before editing, and rules for multi-agent work.

In plain words
What is it for?
Use it when running Maestro’s orchestration workflow, especially for tasks involving multiple agents, planning decisions, tests, or documentation.
Why use it?
It helps agents decide how much process a task needs and keeps work within scope while requiring honest verification.

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 AGENTS.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 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.

How it starts

The opening of the file, as written. The whole thing — 239 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md -- Maestro Orchestration Kernel

Optional discipline layer for AI coding agents. It is independent of Maestro Frontier and is installed only with --with-discipline. The full multi-agent protocol lives in docs/orchestration.md, loaded on demand. S0-S10 are stable identifiers.

Calibrated defaults, not rigid laws — apply judgment, scale to the task. Lead with the work; the S1 gate is a checkpoint just before your first edit, never your opening move. A rule that plainly does not fit yields to doing the task well — say so and proceed. Hard invariants are narrow: verification honesty (S7.3), surgical scope (S7.4), compression integrity (S8).


0. Quality Standard [ALWAYS]

Do the whole thing, right, with tests and docs scaled to the change. Search before building; test before shipping. Bar: genuinely done, within scope.


1. Decision Gate [ALWAYS]

Engage first — read the request, orient on the files it names. The gate is the checkpoint just before your first edit, when you know the real file count; not your opening move.

Output one verdict line — Maestro · frontier <on|off> — files=<n> concerns=<m> -> single-agent — <reason> or Maestro · frontier <on|off> — files=<n> concerns=<m> -> multi-agent — <trigger met>. files = every file created or modified; concerns = distinct areas (commands, core, config, docs, tests). Obvious single-agent work: a one-line reflex. No edits before the verdict. The frontier badge = engine state: frontier on (<mode>/<preset-or-model>) when armed, else frontier off; on Claude Code the gate-reminder hook injects it.

Multi-agent triggers (ANY — check FIRST): 5+ files across 2+ concerns with structurally independent subtasks, >15 messages single-agent, adversarial review, multiple skill domains. File count alone is NOT a trigger — 5+ files in one coherent or sequential change stay single-agent. Multi-agent must be earned by real parallelism, context isolation, or adversarial review; absent one of those, single-agent. A met trigger still downgrades on >60% file overlap between subtasks, or <=3 files in one dependency chain.

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.
