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 | $0.00046 | $0.00274 |
| Opus 5 | $0.00023 | $0.00137 |
| Sonnet 5 | $0.00009 | $0.00055 |
| Haiku 4.5 | $0.00005 | $0.00027 |
Grade A, and why
verify-local-config-before-claims 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 8d 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
Verify Local Config Before Claims
- Inspect local source of truth before answering.
- Read relevant profile files under
profiles/. - Check transport and auth behavior in
src/transport/http-transport.tsand related docs. - Verify route format and profile selection from
README.mdanddocs/HTTP-TRANSPORT.md.
- Confirm claims with concrete evidence.
- Cite exact file paths and key values (profile id, aliases, auth type, env var names, endpoint paths).
- Prefer direct file reads over memory or assumptions.
- Distinguish static config from runtime prerequisites.
- State whether config syntax is valid.
- Separately list runtime conditions required for it to work (enabled transport mode, env vars set, profile routing on).
- Resolve conflicts explicitly.
- If docs and code differ, prioritize code and note the discrepancy.
- If multiple profiles exist, identify which one matches the user snippet.
- Avoid speculative diagnoses.
- Do not claim a field is wrong unless a local check confirms it.
- When unsure, run one more targeted file check before concluding.
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.

verify-local-config-before-claims is a skill published in the GitHub repository davidruzicka/mcp4openapi (0 stars, last pushed 5d ago), licensed MIT. It adds 46 tokens to every session and 274 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 2026-08-31.
