OpenRig is a software harness that coordinates Claude Code and Codex coding agents as one system, with agent teams defined in YAML and launched together. It is for organizing persistent teams of coding agents that can delegate work to specialists and return results or decisions. The catalogue lists 53 skills and one plugin as add-ons for OpenRig.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
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 | $0.00030 | $0.02298 |
| Opus 5.5 | $0.00012 | $0.00919 |
| Sonnet 5.5 | $0.00006 | $0.00460 |
| Haiku 4.5 | $0.00003 | $0.00230 |
Grade A, and why
mission-slice-sop 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 4d 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 — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mission/Slice SOP — Part A
Use this skill to actually do mission/slice work: track on the canonical files, record what you proved, hand off through them, and survive compaction on them. Do the work described here; do not merely explain the protocol.
Full convention SSOT: repo docs/reference/sdlc-conventions.md; installed $OPENRIG_HOME/reference/sdlc-conventions.md. This skill is the concise Part-A teaching surface and does not replace the full convention.
Resolve the work first
Run rig whoami --json, then resolve project.yaml -> mission.yaml -> active slice.yaml -> selected component or wave map -> addressed context. The complete
lookup and precedence rule is docs/reference/product-journey-sdlc.md#resolve-the-selected-path
(installed: $OPENRIG_HOME/reference/product-journey-sdlc.md#resolve-the-selected-path).
Read the selected addresses and source needed for this task; skills available in
your profile are capabilities, not a mandatory reading list. No composition means
light Part A. Role names and idle seats add no gates. Explicit rigor and authored
wave boundaries retain their named checks.
The light inner loop is ground yourself → build → test with your own eyes → iterate → record and return the whole outcome. The builder may hold this check on a tiny change. Independent review runs only when selected, and once at an authored wave boundary rather than once per slice.
Part B is defined in the conventions SSOT and runs only when explicitly assigned to named work. If you believe it is needed, state the reason to the owner and continue on the selected path until that choice changes.
Proportionality — this SOP serves shipping; it is not the work itself
The working product is the deliverable. This bookkeeping exists so the work survives handoff, compaction, and review — nothing more. Match it to stakes. The rig scope audit backstop is advisory and fail-open: it never blocks a build and is not a gate you clear before proceeding. If you're spending more time on the convention files or the audit than on the running product, stop and go build. Running the full apparatus on a small change is the letter-worship failure, not diligence.
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.

mission-slice-sop is a skill published in the GitHub repository mvschwarz/openrig (8,139 stars, last pushed today), licensed Apache-2.0. It adds 30 tokens to every session and 2,298 once invoked, about $0.0001 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.
