Conciseness

Lean throughout — no explanations of concepts Claude already knows, just direct SQL, normalization hints, and a short disambiguation table; every section earns its tokens.

Actionability

Fully executable SQL for each branch (email/name/UUID lookup, UPDATE, verify), explicit MCP tool and project_id, plus a copy-paste response template — concrete and ready to run.

Workflow Clarity

A clearly sequenced 4-step checklist with a disambiguation table handling 0/1/2+ matches, an already-ambassador guard, an explicit verify step, and batch guidance — including validation checkpoints for the database write.

Progressive Disclosure

Well-organized into clear sections with no external bundle files; per the simple-skill note, a self-contained skill this size scores well without separate reference files.

Specificity

Names multiple concrete actions — "Adds Cursor Directory ambassador badges by name or email via Supabase", "Resolves the person", and "sets users.is_ambassador" — with the underlying mechanism, matching the anchor for listing several specific concrete actions.

Completeness

Explicitly answers both what it does (adds badges, resolves the person, sets is_ambassador) and when to use it via a clear "Use when the user asks to add, grant, or promote..." clause.

Trigger Term Quality

Natural user phrasing is well covered: "add, grant, or promote an ambassador, ambassador badge, or Cursor Ambassador" spans the verbs and noun variants a person would actually say.

Distinctiveness Conflict Risk

Targets a narrow niche — Cursor Directory ambassadors via Supabase — with distinct triggers unlikely to collide with unrelated skills.
