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 | $0.00392 | $0.00392 |
| Opus 5.5 | $0.00157 | $0.00157 |
| Sonnet 5.5 | $0.00078 | $0.00078 |
| Haiku 4.5 | $0.00039 | $0.00039 |
Grade A, and why
coderag 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 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
coderag — local agent notes only
Static engineering and delivery standards load from the active Skills runtime (SylphxAI/skills is binding instruction SSOT). Doctrine and Mission Control are retired historical lineage and must not be loaded as current instruction authority.
Local truth: PROJECT.md.
Boundary hazards
- Never commit secrets, tokens,
.envfiles, or credentials.
Local commands
bun run typecheckbun run testbun run lintbun run buildcargo test --workspace- Prefer the narrowest affected check before full workspace runs.
- Report layers honestly: local diff · trunk FF · deploy · prod proof (do not collapse).

Backend false-authority fence
Work: wi_01KYFN6993PMG8WD00Q51AE231
If this repository has completed a Rust backend cutover:
- Production backend behavior authority is the Rust crate/binary/service path declared in
sylphx.toml/ deploy manifests / packagebinnative path / Docker ENTRYPOINT. - Residual TypeScript service trees or alternate TS engines are not product authority unless explicitly proven still on the live path.
- Do not "fix production" by editing residual TypeScript and assuming deploy/runtime will pick it up.
- Prefer deleting residual TS backend trees after Rust sole proof; keep history in Git.
- Intentional TypeScript frontends, npm packaging wrappers, and native-binding surfaces may remain.
Repo-specific note
Rust crates own retrieval/MCP server core; residual TS packages are not production authority without publish proof.
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.

coderag AGENTS.md is an instructions file published in the GitHub repository SylphxAI/coderag (12 stars, last pushed 1mo ago), licensed MIT. It adds 392 tokens to every session, about $0.0016 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 2026-08-30.
