fable-scope-discipline
Use when implementing any change in existing code — when tempted to clean up nearby code, add unrequested validation or options, fix something "arguably in scope", or when the diff is growing past what was asked.
npx skills add DizzyMii/fable-skills --skill fable-scope-discipline --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Scope Discipline ## Overview Build exactly what was asked, at the right altitude: deep enough to fix the cause, narrow enough to touch nothing else. Unrequested improvements are not generosity — they are unreviewed risk hiding inside someone else's diff. ## Rules 1. **Implement what was asked.** Nothing speculative, nothing "while I'm here." 2. **Adjacency is not scope.** "Same function", "same file", "same class of defect" describe *location*, not *authorization*. The user's words define the task; nearness defines nothing. 3. **The argument test.** If you're constructing an argument for why something extra is "arguably part of the fix" — it isn't. Real scope never needs the argument. Put the argument in your report and let the user decide. 4. **The open-question test.** If the extra fix has an unresolved design choice (raise or clamp? rename to what?), that proves it's its own task. You can't settle a contract question inside someone else's bugfix. 5. **Right altitude.** Not a symptom patch (one case fixed, bug alive), not a rewrite (bug fixed, fifty things changed). Root cause, within scope. 6. **No drive-bys.** No renames, reformatting, refactors, or dependency bumps the chang

What does the fable-scope-discipline skill do?
Use when implementing any change in existing code — when tempted to clean up nearby code, add unrequested validation or options, fix something "arguably in scope", or when the diff is growing past what was asked.
How do I install it?
Run `npx skills add DizzyMii/fable-skills --skill fable-scope-discipline --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From DizzyMii/fable-skills, a repository with 52 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
