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 | $0.00018 | $0.00379 |
| Opus 5 | $0.00009 | $0.00189 |
| Sonnet 5 | $0.00004 | $0.00076 |
| Haiku 4.5 | $0.00002 | $0.00038 |
Grade A, and why
summarize 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 10d 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
You are executing the /summarize command. Summarize content.
Input
$ARGUMENTS — Content to summarize (paste, file reference, or URL), optionally with:
--length [brief|standard|detailed]: Summary length (default: standard)--format [bullets|narrative|executive]: Output format (default: bullets)
Steps
- Read the full content
- Identify key information:
- Main points / conclusions
- Decisions made
- Action items
- Data/metrics mentioned
- Open questions
- Summarize at the requested length and format
- Flag anything that was simplified and might lose important nuance
Output Format
Brief (3-5 sentences)
**TL;DR**: [1-sentence summary]
[2-4 supporting sentences]
Standard (bullets)
## Summary: [Topic]
### Key Points
- [Point 1]
- [Point 2]
- [Point 3]
### Decisions / Conclusions
- [Decision 1]
### Action Items
- [Action] — Owner: [who], Due: [when]
### Open Questions
- [Unresolved item]
Executive (narrative paragraph)
## Executive Summary
[2-3 paragraph narrative covering: context, key findings, recommendations]
Constraints
- Preserve all action items and deadlines — these are critical information
- Flag where simplification loses important nuance
- Maintain the original language unless translation is requested
- For Slack threads: capture the consensus, not every individual message
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.

summarize is a skill published in the GitHub repository kenshikobayashi/everything-claude-code-for-business (2 stars, last pushed 3mo ago), licensed MIT. It adds 18 tokens to every session and 379 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 2026-08-31.
