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 | $0.00156 | $0.00156 |
| Opus 5.5 | $0.00062 | $0.00062 |
| Sonnet 5.5 | $0.00031 | $0.00031 |
| Haiku 4.5 | $0.00016 | $0.00016 |
Grade A, and why
ai-architect-mcp-codebase 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 yesterday.
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
ai-architect-mcp-codebase
This is a Rust stdio JSON-RPC server for read-only code graph intelligence.
Read CLAUDE.md, docs/agent-guidance.md and CONTRIBUTING.md before changes or reviews.
Review guidelines
- Preserve MCP wire schemas, reason codes and receipt-style responses. A new tool must include its schema, handler and integration test together, as required by CONTRIBUTING.md.
- Require the existing source-discipline and before/after benchmark evidence for graph-algorithm changes. Do not replace measured graph behavior with guessed edges or unsupported claims.
- Enforce the documented Rust safety rules and zero-warning policy. Public boundaries return Result; unsafe code and production unwrap/expect require their documented justifications.
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.

ai-architect-mcp-codebase AGENTS.md is an instructions file published in the GitHub repository cdeust/ai-architect-mcp-codebase (7 stars, last pushed today), licensed MIT. It adds 156 tokens to every session, about $0.0006 per session on Opus 5.5. 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 2026-10-28.
