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 5.1 | $0.00207 | $0.00207 |
| Opus 5 | $0.00103 | $0.00103 |
| Sonnet 5 | $0.00041 | $0.00041 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
template 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 5d 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
Skill Evaluator
Evaluate AI skills across model tiers with blind testing and refinement recommendations.
Overview
This extension tests AI skills across model tiers (opus → sonnet → haiku) using blind sub-agent testing. It identifies where skill clarity degrades and provides actionable refinement recommendations.
Usage
Use the /evaluate command to start an evaluation:
/evaluate <skill-path> <test-cases-path>
skill-path: Path to the SKILL.md file to evaluatetest-cases-path: Path to a JSON file with test cases (array of{ input, expectedOutcome })
How It Works
- The experimenter agent reads the skill and test cases
- Separate blind test-subject agents are spawned per test case at the highest tier (opus)
- The process repeats at lower tiers (sonnet, then haiku)
- Results are compared against expected outcomes per tier
- A refinement report identifies where clarity breaks down and recommends improvements
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.

template GEMINI.md is an instructions file published in the GitHub repository ai-plugin-marketplace/template (10 stars, last pushed 2mo ago), licensed MIT. It adds 207 tokens to every session, about $0.0010 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.
