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.

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 | $0.00281 | $0.00281 |
| Opus 5 | $0.00140 | $0.00140 |
| Sonnet 5 | $0.00056 | $0.00056 |
| Haiku 4.5 | $0.00028 | $0.00028 |
Grade A, and why
maestro GEMINI.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 3d 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.

Gemini Runtime Notes
Precedence
This file takes precedence over AGENTS.md when both are present.
Portable orchestration doctrine is imported above — only
Gemini-specific behavior belongs here.
Execution Mapping
- Single-agent mode — standard Gemini execution, no overhead.
- Multi-agent mode — use Gemini sub-agents for independent parallel work when the Decision Gate (Section 1) qualifies the task.
- Do not assume Claude Code features (hooks, agent teams, per-subagent tool restriction) are available. Use only verified Gemini capabilities.
Instruction Organization
- Use
@./path/to/file.mdimports to share instructions without duplication. - Keep runtime-specific rules in this file; portable rules in
AGENTS.md.
Verification
When Section 7.3 requires type-checking or linting, use the project's configured tooling. Do not assume specific CLI tools — check project configuration first.
Long-Horizon Operation (S10 mapping)
Gemini CLI has no native scheduler — recurring runs come from external schedulers or Gemini Enterprise scheduled agents. Section 10 applies unchanged: checkpoint artifact read first on every run, explicit end condition, final report on completion. Verify scheduling capabilities before assuming them.
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.

maestro GEMINI.md is an instructions file published in the GitHub repository mbanderas/maestro (5 stars, last pushed 6d ago), licensed MIT. It adds 281 tokens to every session, about $0.0014 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 2026-08-31.
