Rig Lifecycle is an agent skill from mvschwarz/openrig. Use when reasoning about the rig lifecycle operations family (create / start / stop / resume / restore / snapshot / release / unclaim / destroy), reading or trusting rig ps / lifecycle projections after recovery, or designing proof for a lifecycle scenario. Covers the 4 failure modes (auto-restore creates partial rig; projections report healthier than reality; provider auth treated as impl work; resume succeeds for one runtime fails another) plus the restore-honesty rule (failed resume is FAILED loudly — no auto…
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. The repository describes itself as: Build your own network of agents from Claude Code, Codex and Pi: persistent teams with roles, shared context and owned work. The licence is Apache-2.0.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit a7fed63. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Rig Lifecycle loads about 1.5k tokens when it runs. Until then it costs about 138 tokens; SKILL.md has 627 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/rig-lifecycle/SKILL.md (or your agent's skills folder).The family of operations that create, start, stop, resume, restore, snapshot, release, unclaim, and destroy OpenRig-managed topologies. Includes the user story after reboot: "bring my work back without turning a clean recovery into a cleanup project."
If lifecycle is brittle, every higher-level primitive inherits that brittleness. Queue, workflow, seat continuity, cross-host operation, and RSI all assume that rigs and seats can be restored into known states.
rig up / down / restore / resume / snapshot / release / unclaim / destroyrig ps after a reboot or recovery and deciding what to trustresumed / rebuilt / fresh / failed / attention_required)openrig-user skill for CLI surfaceopenrig-operatoropenrig-architectrig ps or lifecycle projections report a healthier state than the runtime actually has. Projections are summaries; the runtime is truth. Don't trust projections silently.Failed resume is FAILED loudly. No automatic fresh fallback. Fresh
launch is explicit follow-up only. This is enforced architecturally
at the daemon level (per architecture.md §7 rule 15).
The locked restore-outcome vocabulary:
| Outcome | Meaning |
|---|---|
resumed | Native runtime resumed the same conversation |
rebuilt | New process assembled from artifacts (session_source: mode: rebuild) |
fresh | New process with no prior continuity |
failed | Restore attempted and failed; no automatic fallback |
attention_required | Recoverable blocker (provider auth refused, etc.); needs operator action |
n-a | Not applicable (terminal nodes, etc.) |
Codex auth-refusal returns attention_required (recoverable); Claude
looksLikeClaudeLoginPrompt returns failed/login_required (terminal).
Cross-runtime alignment is an open follow-up question.
Lifecycle proof should include real reboot or VM-reboot evidence, not only daemon-unit evidence. The minimum useful matrix covers:
| Scenario | What it proves |
|---|---|
| Clean start | Boot from spec into known state |
| Warm resume | rig down → rig up <name> resumes seats |
| Host reboot / tmux socket absence | Recovery from lost tmux connection |
| Provider auth loss | Codex/Claude auth refusal handled honestly |
| Partial boot / partial failure | Some seats up, some failed; honest reporting |
| Intentional operator recovery | Operator-initiated restore from snapshot |
Tier 1: in-process bedrock (daemon-unit evidence). Tier 2: real reboot or disposable Tart VM. Tier 1 alone is not lifecycle proof; it's bedrock.
Treat default policy as part of the primitive, not an afterthought. Lifecycle defaults that are too optimistic for the reliability level actually proven create silent harm:
auto-restore defaults that mask failure modesThe rail sequences restore truth into four rungs:
fully_restored is a Rung 3 execution rollupNaming discipline matters. "Fully restored" and "fully back" are different claims; don't conflate.

Rig Lifecycle is an agent skill from mvschwarz/openrig. Use when reasoning about the rig lifecycle operations family (create / start / stop / resume / restore / snapshot / release / unclaim / destroy), reading or trusting rig ps / lifecycle projections after recovery, or designing proof for a lifecycle scenario.
Rig Lifecycle fits situations like: reasoning about the rig lifecycle operations family (create / start / stop / resume / restore / snapshot / release / unclaim / destroy); trusting rig ps / lifecycle projections after recovery; designing proof for a lifecycle scenario.
Run `npx skills add mvschwarz/openrig --skill rig-lifecycle -a claude-code`. Or copy the skill folder (skills/_canonical/core/rig-lifecycle in mvschwarz/openrig) into .claude/skills/rig-lifecycle in your project. Claude Code loads it when a task matches its description.
Run `npx skills add mvschwarz/openrig --skill rig-lifecycle -a codex`. Or copy the skill folder (skills/_canonical/core/rig-lifecycle in mvschwarz/openrig) into .agents/skills/rig-lifecycle in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mvschwarz/openrig --skill rig-lifecycle -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/rig-lifecycle, .gemini/skills/rig-lifecycle, .github/skills/rig-lifecycle and .opencode/skills/rig-lifecycle in your project.
SKILL.md names no scripts, command-line tools or credentials: Rig Lifecycle is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Rig Lifecycle is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.5k tokens (SKILL.md is roughly 6.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Rig Lifecycle: MCP Server Builder (anthropics/skills, 180k stars), Hook Development for Claude Code Plugins (anthropics/claude-plugins-official, 37k stars), Using Superpowers (farm-fe/farm, 5.6k stars) and Executing Plans Inline (obra/superpowers, 296k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
