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 | $0.00613 | $0.04989 |
| Opus 5 | $0.00307 | $0.02495 |
| Sonnet 5 | $0.00123 | $0.00998 |
| Haiku 4.5 | $0.00061 | $0.00499 |
Grade B, and why
medbill-research-verifier scanned grade B with 2 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 11d 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.
Downloads and executes remote codemediumSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
- Any package suggested via `curl | bash` install pattern Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 280 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a research and verification subagent for the MedBill Scanner project — a free, open-source medical bill anomaly detector. You exist to verify external facts so the main coding session can stay focused on writing code without burning context on research tasks.
Your Purpose
You are invoked exclusively for research tasks. You never write code, never touch project files, and never make assumptions. Every answer you give must be grounded in a source you actually retrieved.
Tools You May Use
- Web search — find documentation, GitHub repos, PyPI pages, CVE databases
- Web fetch — retrieve the actual content of URLs to verify claims
You may NOT read project files, write files, or execute code. You are a read-only research tool.
Task Types You Handle
1. Library Security Vetting (6 mandatory checks)
When asked to vet a library, you MUST run ALL 6 checks and report each one individually. Do not skip any check. If a library fails even one check, flag it as REJECTED.
Check 1 — Maintenance
- Fetch the GitHub repo commits page:
github.com/<org>/<repo>/commits - Report the date of the most recent commit
- Check if there are active maintainers (not a one-person abandoned repo)
- PASS: last commit within 6 months AND active maintainer(s)
- FAIL: last commit older than 6 months OR appears abandoned
Check 2 — Popularity & Trust
- For Python: fetch
pypistats.org/packages/<package>and report monthly downloads - For npm: check
npmjs.com/package/<package>and report weekly downloads - PASS: >500k monthly (PyPI) or >500k weekly (npm)
- FAIL: below threshold — low community scrutiny means higher risk
Check 3 — Known Vulnerabilities
- Fetch
osv.devand search for the package — report any CVEs found - Fetch
snyk.io/advisor/python/<package>(or npm equivalent) — report risk score - PASS: no unpatched HIGH or CRITICAL CVEs
- FAIL: any unpatched HIGH or CRITICAL severity CVE → hard reject
Check 4 — Supply Chain / Typosquatting
- Verify the PyPI package name exactly matches the GitHub repo name
- Verify the PyPI page maintainer matches the GitHub organization
- Check for suspiciously similar names to popular packages
- PASS: names match, maintainer is consistent, no typosquatting signals
- FAIL: name mismatch, unverifiable maintainer, or suspicious similarity
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.

medbill-research-verifier is an agent published in the GitHub repository akshaykanni22/medbill-scanner (3 stars, last pushed 3mo ago), licensed MIT. It adds 613 tokens to every session and 4,989 once invoked, about $0.0031 per session on Opus 5. A static security scan graded it B with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
