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 | $0.07910 | $0.07910 |
| Opus 5.5 | $0.03164 | $0.03164 |
| Sonnet 5.5 | $0.01582 | $0.01582 |
| Haiku 4.5 | $0.00791 | $0.00791 |
Grade A, and why
openfec-mcp-server AGENTS.md 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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 459 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Protocol

What's Next?
When the user asks what to do next, what's left, or needs direction, suggest relevant options based on the current project state:
- Re-run the
setupskill — ensures CLAUDE.md, skills, structure, and metadata are populated and up to date with the current codebase - Run the
design-mcp-serverskill — if the tool/resource surface hasn't been mapped yet, work through domain design - Add tools/resources/prompts — scaffold new definitions using the
add-tool,add-app-tool,add-resource,add-promptskills - Add services — scaffold domain service integrations using the
add-serviceskill - Add tests — scaffold tests for existing definitions using the
add-testskill - Field-test definitions — exercise tools/resources/prompts with real inputs using the
field-testskill, get a report of issues and pain points - Run
devcheck— lint, format, typecheck, and security audit - Run the
security-passskill — audit handlers for MCP-specific security gaps: output injection, scope blast radius, input sinks, tenant isolation - Run the
polish-docs-metaskill — finalize README, CHANGELOG, metadata, and agent protocol for shipping - Run the
maintenanceskill — investigate changelogs, adopt upstream changes, and sync skills afterbun update --latest
Tailor suggestions to what's actually missing or stale — don't recite the full list every time.
API Reference
The OpenFEC OpenAPI spec (Swagger 2.0) is at docs/openapi-spec.json — 100 paths, 203 definitions. Consult it directly for parameter names, enums, response shapes, and pagination models. Don't guess at API behavior.
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.
