Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00152 | $0.28800 |
| Opus 5 | $0.00076 | $0.14400 |
| Sonnet 5 | $0.00030 | $0.05760 |
| Haiku 4.5 | $0.00015 | $0.02880 |
Grade A, and why
odin-scp 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 2d 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.
This is a copy
100% identical to odin-scp — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 1,848 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sentinel Coordination Protocol
SCP_PUBLIC_VERSION: 0.6.0 MIN_COMPATIBLE_CHILD_MCP: 0.4.5
Public install readiness: configure the ODIN MCP server, install native skill context where supported or use full prompt fallback, keep governed team roles in CMUX, verify auth/account readiness without printing secrets, smoke-test local inference if used, and validate role compatibility before launch. Private local skill copies may differ intentionally; public release checks compare repo-internal public artifacts only.
Use this skill for SCP policy introduction, repo landing, adoption-gate proof, controlled dissemination, active multi-agent control loops, and automated team lifecycle management. SCP is a governance layer for multi-team agent operation; it complements other coordination layers and AGENTS.md files where present. It sits above them after activation.
Source Of Truth
Master editable source:
- the repository-distributed SCP protocol bundle, or an operator-declared canonical SCP skill source outside this public package.
The active canonical SCP skill directory is the directory that contains this SKILL.md plus its references/, agents/, and scripts/ support files.
All installed copies are synchronized runtime snapshots, not independent policy forks. Any agent modifying SCP policy must edit the declared source first, then propagate the full skill/protocol bundle to the installed harness targets and verify matching hashes.
Use the operator-declared sync procedure after edits. Do not hand-edit generated runtime copies except as a temporary emergency patch that is immediately backported to the declared source and resynced.
Portable curated skill/session records may live under the declared source, for example decisions/YYYY-MM-DD-<slug>.md and optionally CHANGELOG.md. Raw audit evidence belongs under .odin/audit/<session-id>/ or the declared evidence_path. Do not create empty folders just to satisfy policy; create decisions/ only when writing the first curated decision record.
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-scp is a skill published in the GitHub repository bradheitmann/odin-sentinel (2 stars, last pushed 5d ago), licensed MIT. It adds 152 tokens to every session and 28,800 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to odin-scp, differing in 0 lines, and is treated as a copy.
Other skills, from other repositories
parallel-feature-development
Coordinate parallel feature development with file ownership strategies, conflict avoidance rules, and integration patterns for multi-agent implementation. Use this skill when decomposing a large feature into independent work streams, when two or more agents need to implement different layers of the same system…
track-management
Use this skill when creating, managing, or working with Conductor tracks - the logical work units for features, bugs, and refactors. Applies to spec.md, plan.md, and track lifecycle operations.
sdd-tasks
Break an SDD change into implementation tasks. Trigger: orchestrator launches task planning for a change.
mission-control
Interact with Mission Control — AI agent orchestration dashboard. Use when registering agents, managing tasks, syncing skills, or querying agent/task status via MC APIs.
autotask-creator
Rules for automation CRUD from the group-chat commander. The commander does not call mutation tools and does not edit cloud/autotasks files directly. It emits one or more top-level ... containers in its final text; the bus parses and applies them after the turn.
project-tasks
Use this protocol to create, update, execute, or complete the structured projecttasks backlog in a Project conversation.
