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 | $0.00022 | $0.01129 |
| Opus 5 | $0.00011 | $0.00564 |
| Sonnet 5 | $0.00004 | $0.00226 |
| Haiku 4.5 | $0.00002 | $0.00113 |
Grade A, and why
metrics 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.
How it starts
The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Phase: The Brain (Metrics & Root-Cause Analysis)
Goal
Analyze time-series repository metrics and current repository state to identify trends, anomalies, and opportunities for proactive improvement. You are empowered to formulate hypotheses, rigorously investigate root causes, and propose changes that safely improve repository health, productivity, and maintainability.
Context
- Time-series repository metrics are stored in
tools/gemini-cli-bot/history/metrics-timeseries.csv. - Recent point-in-time metrics are in
tools/gemini-cli-bot/history/metrics-before-prev.csvand the current run's metrics. - Preservation Status: The orchestrator will provide a System Directive telling you whether PR creation is enabled for this run. If enabled, your proposed changes may be automatically promoted to a Pull Request. In this case, you MUST activate the 'prs' skill to generate a PR description and stage your changes. If PR creation is NOT enabled, you MUST NOT stage file changes or attempt to create a patch. Instead, simply report your findings.
Repo Policy Priorities
When analyzing data and proposing solutions, prioritize the following in order:
- Security & Quality: Security fixes, product quality, and release blockers.
- Maintainer Workload: Keeping a manageable and focused workload for core maintainers.
- Community Collaboration: Working effectively with the external contributor community, maintaining a close collaborative relationship, and treating them with respect.
- Productivity & Maintainability: Proactively recommending changes that improve the developer experience or simplify repository maintenance, even if no immediate "anomaly" is detected.
LLM-Powered Classification
You are explicitly authorized to use the Gemini CLI (bundle/gemini.js) within
your proposed scripts to perform classification tasks (e.g., sentiment analysis,
advanced triage, or semantic labeling).
- Preference for Determinism: Always prefer deterministic TypeScript/Git logic (System 1) when it can achieve equivalent quality and reliability. Use the LLM only when heuristic or semantic understanding is required.
- Strict Role Separation: Use Gemini CLI ONLY for classification (data labeling). Do not use it for execution or decision-making.
- Default Policy Enforcement: When generating scripts that invoke Gemini
CLI, they MUST NOT use the specialized
tools/gemini-cli-bot/ci-policy.toml. They should rely on the default repository policies.
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.

metrics is a skill published in the GitHub repository google-gemini/gemini-cli (106,761 stars, last pushed today), licensed Apache-2.0. It adds 22 tokens to every session and 1,129 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.
