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 | $0.00325 |
| Opus 5 | $0.00011 | $0.00162 |
| Sonnet 5 | $0.00004 | $0.00065 |
| Haiku 4.5 | $0.00002 | $0.00032 |
Grade A, and why
check-vulns 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 4d 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
Check all package-lock.json files for known npm vulnerabilities using npm audit (GitHub Advisory Database).
Check
Run ./scripts/check-vulns.sh --force to bypass cache and scan now.
Then read the digest at .claude/.update-cache/vulns-digest.md and present findings to the user, organized by severity. Highlight:
- Any new vulnerabilities since last scan
- Fix recommendations (quick fixes vs major bumps)
- Acknowledged vulns that are being tracked but suppressed
Acknowledge Known Vulns
If the user wants to suppress session-start alerts for vulns that cannot be fixed yet (e.g., requires a semver-major bump):
- Run
./scripts/check-vulns.sh --acknowledge <GHSA-URL>where the URL is from the digest - The vuln still appears in the digest but won't trigger session-start alerts
- Acknowledgements auto-clear when the vuln is resolved
Fix Vulns
For quick fixes:
- Run
npm audit fixin the affected directory - Verify tests pass:
npm test - Commit lock file changes
For major-bump fixes:
- Cross-reference with
/check-depsfor the same package - Review changelog and breaking changes before upgrading
- Apply with
npm install package@latest

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.

check-vulns is a command published in the GitHub repository wittyreference/twilio-claude-plugin (2 stars, last pushed 3mo ago), licensed MIT. It adds 22 tokens to every session and 325 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.
