Code comment standards
- Comment WHY, not WHAT. The code shows what. Comments explain intent.
- ✅
// We use bcrypt cost 14 here because this is the admin auth path — speed is not critical - ❌
// Hash the password - Remove TODO comments before committing to main. Create a ticket instead.
- Every exported function needs a JSDoc/docstring with: description, params, return, throws.
JSDoc template
/**
* Verifies a JWT access token and returns the decoded payload.
*
* @param token - The raw JWT string from the Authorization header
* @returns Decoded token payload containing userId and role
* @throws {TokenExpiredError} If the token has passed its expiry time
* @throws {InvalidTokenError} If the token signature is invalid
*/
export function verifyAccessToken(token: string): TokenPayload { ... }
Changelog discipline
Every user-visible change must appear in the changelog before release: create
changelogs/vX.Y.Z.md for the new release, then prepend the same entry (or a
one-line summary + link) into root CHANGELOG.md's rolling window, dropping
the oldest entry if the window exceeds 10 versions.
Format follows Keep a Changelog (keepachangelog.com).
Categories: Added, Changed, Deprecated, Removed, Fixed, Security.
Self-check before task completion
Before marking a task done when this skill was active:
- Did I read the full SKILL.md before starting? (Not just the triggers)
- Did I activate the corresponding persona file?
- Did I apply every mandatory action in this skill, not just the ones I remembered off the top of my head?
- If this skill produced an output file (review, security report, etc.), has that file been written to the correct path?
