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.

What it costs to keep this loaded
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 | $0.00032 | $0.00429 |
| Opus 5 | $0.00016 | $0.00215 |
| Sonnet 5 | $0.00006 | $0.00086 |
| Haiku 4.5 | $0.00003 | $0.00043 |
Grade A, and why
yutori-api-monitor 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 12d 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
API & Changelog Monitoring
Set up monitoring for API or service changes.
Create a scout with this query structure:
**Context:** Monitoring API stability and changes for $ARGUMENTS to ensure our integration stays up-to-date.
## What to Monitor
- **Breaking Changes:** API version changes, deprecated endpoints, removed features
- **New Features:** New endpoints, parameters, capabilities
- **Rate Limits & Quotas:** Changes to limits, pricing tier updates
- **Deprecation Notices:** Sunset timelines, migration guides
- **Security Updates:** Authentication changes, security advisories
**Sources to check:** Official changelog, documentation, developer blog, GitHub releases, status page, developer Twitter/X account
**Exclusions:** Minor bug fixes, internal refactoring, documentation typos
## Deliverables
**Frequency:** Every 12 hours
**Output format:**
1. **URGENT** section for breaking changes (if any)
2. Table of changes: Date, Type (breaking/feature/deprecation), Description, Migration Required (yes/no), Source Link
3. Recommended actions for each change
Use create_scout with:
query: The above structured query with $ARGUMENTS replacedoutput_interval: 43200 (every 12 hours)
After creation, explain:
- Scout will check twice daily for changes
- Critical for staying ahead of breaking changes
- Can set up webhook for immediate notifications
Fetching API documentation or changelogs:
If you use a web fetch tool to look up the service's changelog, API reference, or developer docs while preparing the query, include the Accept: text/markdown header. Many developer documentation sites (Cloudflare-hosted) will return clean Markdown instead of HTML — fewer tokens, easier to parse.
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.

yutori-api-monitor is a skill published in the GitHub repository yutori-ai/yutori-mcp (24 stars, last pushed today), licensed Apache-2.0. It adds 32 tokens to every session and 429 once invoked, about $0.0002 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.
