Rig Bundles And Shareable Artifacts is an agent skill from mvschwarz/openrig. Use when authoring or installing a rig bundle (packaged, shareable artifact that instantiates an opinionated OpenRig topology + workflow), reasoning about the bundle vs extension boundary, or auditing a bundle for portability. Covers the 4 failure modes that prevent bundles from working anywhere but the operator's machine, and the inspect-before-install discipline.
Its SKILL.md is about 1.1k 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 4b48ca2. 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 Bundles And Shareable Artifacts loads about 1.1k tokens when it runs. Until then it costs about 101 tokens; SKILL.md has 452 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-bundles-and-shareable-artifacts/SKILL.md (or your agent's skills folder).A rig bundle is a packaged, shareable artifact that can instantiate an opinionated OpenRig topology and workflow. It may include:
Shareable artifact is broader than bundle: specs, bundles, skills, workflows, and extensions can all be shared. A bundle is the packaged form for "load this topology and way of working."
rig bundle install <path>)rig bundle inspect <path>)extension-and-user-workspace, not bundles.| Concept | Declares | Example |
|---|---|---|
| Bundle | Rig shape + workflow ("load this topology and way of working") | A Velocity Team bundle |
| Extension | Behavior added to user workspace/runtime | A custom command, view, or dashboard |
Don't confuse them. A bundle is opinionated content; an extension is added behavior. Both can be shareable artifacts, but they're structurally distinct.
rig bundle inspect must show what will be created without side effects.Proof should:
Bundles are how proven lab patterns become reusable product experiences:
local dogfood pattern
→ bundle (with manifest, parameterization, proof expectations)
→ installed by another user on clean OpenRig
→ opinionated workflow shipped without becoming a daemon feature
→ if dependable, graduate parts into core daemonThis is also how OpenRig can ship opinionated workflows without making every workflow a daemon feature.
