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 | $0.00000 | $0.00894 |
| Opus 5 | $0.00000 | $0.00447 |
| Sonnet 5 | $0.00000 | $0.00179 |
| Haiku 4.5 | $0.00000 | $0.00089 |
Grade A, and why
example-summarize-notes 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.

Example Skill: Summarize Notes with NotebookLM
Skill Purpose
Help an AI agent take a collection of notes (Markdown, text, transcripts) in this repo and produce a concise, grounded summary that can be safely added back to README.md or AGENTS.md.
When to Use This Skill
- You have 2–20 small notes, docs, or transcripts that all relate to the same topic.
- You want a short summary (1–3 paragraphs or 3–7 bullets) capturing key ideas for developers.
- You want the summary to be grounded in the source material, not hallucinated.
Inputs
note_paths: list of file paths (relative to repo root) to summarize.summary_style(optional): one ofbullets,paragraph, ormixed.target_audience(optional): short description, e.g.backend engineers,ML platform team.
High-Level Workflow
- Collect the contents of all
note_paths. - Optionally use an external grounding tool like NotebookLM for deeper analysis.
- Ask the model to propose a candidate summary.
- Cross-check the summary against the source notes; remove unsupported claims.
- Emit a final summary plus a short "How to integrate into this repo" suggestion.
Detailed Agent Instructions
Follow these steps whenever this skill is invoked:
-
Load Inputs
- Read all files listed in
note_paths. - If any file is missing or empty, report which ones and continue with the rest.
- Read all files listed in
-
Normalize Content
- Strip boilerplate (license headers, navigation, TOCs) where obvious.
- Preserve code snippets and CLI commands exactly; do not rewrite them.
-
Grounded Analysis (Optional NotebookLM Step)
- If NotebookLM is available:
- Create or update a NotebookLM notebook with the note contents.
- Ask NotebookLM for 3–5 key takeaways and 3 concrete examples or use cases.
- Use those responses as additional context, but do not copy phrasing verbatim.
- If NotebookLM is not available, skip this step and rely on local analysis.
- If NotebookLM is available:
-
Draft Summary
- If
summary_styleisbullets, produce 3–7 bullets. - If
summary_styleisparagraph, produce 1–3 short paragraphs. - If
summary_styleismixedor not provided, use 1 short paragraph plus 3–5 bullets. - Target audience:
- If
target_audienceis provided, emphasize what matters for that audience. - Otherwise, assume "software engineers adopting AI tooling".

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.

example-summarize-notes is a skill published in the GitHub repository eficode/modern-ai-developer-stack (11 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 894 tokens. 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.
