Capability node
Scope Definition
Draw the boundary of what a skill or task does and does not do.
Why this capability exists
Skills fail when they try to do everything. A clear scope makes triggers predictable, testing possible, and expectations honest.
Input
- The task the skill should handle
- Examples of adjacent tasks it should refuse
Output
- One-sentence scope statement
- Explicit out-of-scope list
- Success criteria for the bounded task
Risks
- A scope so broad it cannot be tested
- Edge cases that silently expand the skill's promises
- Duplicating another skill's responsibility
Acceptance criteria
- Scope fits in one sentence
- At least three out-of-scope examples are documented
- Every in-scope behavior has a testable outcome
