Design a `co <thing>` CLI surface and its SKILL.md together so an agent can drive it without guessing — help teaches the workflow and serves as the skill source of truth, every command names the next step, and failures explain recovery; every page passes the CI help contract (example, what it changes, a way back). Use when adding a new CLI command group, writing or rewriting a SKILL.md for one, or auditing an existing one.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Designing a CLI skill Design command help as a usage skill for both people and agents. The help page is the source of truth for choosing and using a command: purpose, inputs, procedure, effects, verification and recovery. An agent should be able to learn correct usage from help, execute a command, and continue from its actual output. Keep one authored workflow definition. Render terminal help and, where supported, a loadable Skill from that definition. Derive command names, arguments, defaults and required flags from the CLI registration. Author workflow and evidence requirements explicitly; function signatures alone cannot explain them. A separate SKILL.md can route to relevant help and add domain judgment without maintaining a second copy of command syntax. This is a design requirement, not a claim that an existing CLI already generates Skills from its help. `co-browser` is the worked example. Read it before you write anything: its exit-code table, its "read the output, not just the exit code" rule, and its Done checklist are what this methodology generalizes.

How to install
mdr add openonion/connectonion/cli-skill-design@sha256:6b2e395aa3f5d2a0The line at the top of this page pins the label git:20260930.715ff0c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
