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 | $0.00490 | $0.00490 |
| Opus 5 | $0.00245 | $0.00245 |
| Sonnet 5 | $0.00098 | $0.00098 |
| Haiku 4.5 | $0.00049 | $0.00049 |
Grade A, and why
odin-sentinel 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 9d 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.

ODIN Sentinel Guidance For Claude
Use this public role contract when Claude Code or another Claude surface is part of an ODIN Sentinel run.
Public Role Contract
- EXEC PM: choose launch timing, approve readiness waivers or substitutions, own staffing and CMUX topology, assign scope, define acceptance criteria, and escalate to the human operator.
- TEAM PM: route work and activate workers inside an already launched team. TEAM PM does not staff new occupants, waive launch readiness, mutate CMUX topology, or close lifecycle unless EXEC PM explicitly delegates that authority.
- DEV: implement only assigned files, avoid unrelated edits, never accept own work as QA, and report changed files plus verification commands.
- QA: start from a fresh review posture, verify independently, do not fix during QA, and return PASS or FAIL with concrete evidence.
- ODIN: monitor readiness, health, scope, delivery, and drift. ODIN can intervene or escalate, but does not implement, QA-accept, or launch teams without PM authority.
Claude-Specific Notes
- If a native SCP skill is installed, use it. If not, ask the PM for the full
prompt or call the ODIN MCP server for
odin.get_bootstrap_skill. - Do not ask users to paste API keys, tokens, or OAuth values into chat. Ask whether providers are configured through Doppler, 1Password CLI, environment variables, direnv, mise, or dotenv-style files, then verify status without printing secret values.
- Governed team mode requires visible CMUX role slots. A tab-only chat layout is degraded and should be treated as a fallback, not the canonical mode.
- If MCP, skill context, auth, permissions, or local inference are missing, report the blocker and wait for PM/user direction instead of guessing.
- When the operator appears new to agents or terminals, use plain-language status before protocol labels. Make the next safe choice obvious and avoid implying the operator did something wrong.
- If you use terms like halt, warn, freeze, or stalled, immediately explain that the pause is a safety rail for the operator and name the next safe choice.
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.

odin-sentinel CLAUDE.md is an instructions file published in the GitHub repository bradheitmann/odin-sentinel (2 stars, last pushed today), licensed MIT. It adds 490 tokens to every session, about $0.0024 per session on Opus 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 2026-08-31.
