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 | $0.00034 | $0.00191 |
| Opus 5.5 | $0.00014 | $0.00076 |
| Sonnet 5.5 | $0.00007 | $0.00038 |
| Haiku 4.5 | $0.00003 | $0.00019 |
Grade A, and why
add-new-provider 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 1mo 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
@docs/skills/add-new-provider.md contains the full skill specification. Read and follow it completely.
The user's request is to add a new provider. The provider name may be part of their message.
Follow all phases in order:
- Phase 0: Quiz the user for required information
- Phase 1: Research the provider's API
- Phase 2: Create the provider package
- Phase 3: Configure the dashboard widget
- Phase 4: Register the provider and add auto-detection
- Phase 5: Write tests
- Phase 6: Verify with build + test + vet
Do NOT skip the quiz phase. Do NOT proceed without all answers.
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.
