Who it is forA developer or founder with a feature idea for a GitHub repo who wants it written up as a build-ready contract before any code is written.
The problemVague feature requests produce confident but wrong pull requests, and writing precise acceptance criteria takes time.
The outcomeA Linear issue with observable acceptance criteria (AC-N) and binding non-goals (NG-N), labeled agent-ready only after the human approves it.
What you need first
- A Git repository hosted on GitHub with a working origin remote
- Claude Code 2.1.71 or newer
- A Linear workspace and team with the Linear connector enabled in Claude Code
- The GitHub CLI (gh) authenticated with write access to the target repo
- At least one required GitHub status check if you want fully automated loop-approved verdicts
Steps
- Open Claude Code inside the target repo and run
/finn-spec. - Answer the interview questions until the behavior is unambiguous; the skill researches the repo first.
- Read the filed Linear issue and check each AC-N and NG-N against what you want.
- If you approve the exact contract, apply the agent-ready label in Linear yourself.
Prompt for your agent
In the GitHub repo at <repo path>, run the /finn-spec skill for this idea: <idea text>. Expected output: one Linear issue with AC-N acceptance criteria and NG-N non-goals. Verify that every acceptance criterion describes an observable outcome before reporting the issue link.
Caveat. The README says spec quality is the bottleneck, so the interview is only as good as the answers you give it.
