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 | $0.00781 | $0.00781 |
| Opus 5.5 | $0.00312 | $0.00312 |
| Sonnet 5.5 | $0.00156 | $0.00156 |
| Haiku 4.5 | $0.00078 | $0.00078 |
Grade A, and why
building-standards-act-mcp CLAUDE.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 18d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
building-standards-act-mcp

Architecture
- Tool pattern:
src/tools/xxx.tsexportsregisterXxxTool(server), registered insrc/server.ts(12 tools). Tools useserver.registerTool()withtitle, read-onlyannotations, andoutputSchema+structuredContentwhere the result is structured - Lib pattern: Business logic lives in
src/lib/; tools handle only formatting + error wrapping viawrapToolHandler - Law resolver:
src/lib/law-resolver.ts— abbreviation expansion + e-Gov API search for dynamiclaw_idresolution - Alias map:
src/data/law-aliases.ts— 116 laws withtitle,abbrev,group - Error handling:
src/lib/tool-helpers.ts— centralized error sanitization + audit logging for all tools - Test pattern:
vi.mock()for egov-client/egov-parser,mockServer.registerToolto capture handlers

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.
