validate-spec

Check a spec for completeness, internal consistency, and adherence to SDD principles.

When to use

• Before changing a spec's status from Draft → Approved
• Before changing a spec's status from Approved → Implemented
• When asked to review a spec

Checklist

Run each check and report findings. Fix issues inline if possible; flag for human review if not.

Required sections

• Status field present and valid (Draft / Approved / Implemented / Deprecated)
• What section present and non-empty
• Why section present and non-empty — "Why" is never optional
• Command surface / API section present (or explicitly noted as N/A with justification)
• Link to .feature file present
• .feature file exists at the linked path

Content quality

• What describes observable behavior, not implementation internals
• Why explains the problem, not just restates the What
• Design decisions section present if any non-obvious choices were made
• No placeholder text ("TBD", "TODO", "...", empty sections)
• No contradictions between sections

.feature file quality

• At least one happy-path scenario per operation in the command surface
• At least one error-case scenario per operation
• Scenarios use BDD language (Given/When/Then)
• Scenarios describe observable behavior only (no internal state references)
• --json scenarios present if the command supports --json

Status consistency

• If status is Implemented: confirm passing tests exist that correspond to the scenarios
• If status is Approved: confirm the spec has been reviewed (PR approval or recorded acknowledgment)
• If status is Draft: no implementation exists yet (or backfill is in progress)

Output

Report:

• PASS / FAIL per check
• Summary: how many checks passed, how many failed
• List of required fixes before the spec can advance to the next status
