Conciseness

Prose is lean and non-obvious comments earn their place ('// Required for Supabase pooling', '// Admin client (bypasses RLS)'), but the body is heavily duplicated: the same posts CRUD appears in full in 'src/routes/posts.ts', again in 'src/db/queries/posts.ts', and a third time in the Hono alternative. This matches anchor 3 ('mostly efficient but could be tightened') — below 4 because the duplication is more than minor, above 2 because nothing explains concepts Claude already knows.

Actionability

Nearly all code is complete, executable, and copy-paste ready (full imports, zod schemas, drizzle-kit scripts), matching anchor 4. It falls short of anchor 5 due to explicit stubs: the Hono middleware contains only '// Verify with Supabase...', tests/setup.ts has empty beforeAll/afterAll bodies, and the storage upload snippet floats without its router/import context.

Workflow Clarity

The setup sequence is coherent but only implicit in section order (install → env → config → db → middleware → routes → app → tests), with no validation checkpoints anywhere (no 'supabase start', no health-endpoint or migration verification, no test-run gate) despite database operations being a feedback-loop context. This is anchor 3 ('sequence present but checkpoints missing or implicit') — not 4 because validation is wholly absent rather than a minor gap, not 2 because the ordering is clear and complete.

Progressive Disclosure

No bundle files exist and nothing is split out: the full route library, Hono variant, storage endpoint, and testing guide are all inlined in a single ~830-line SKILL.md, though under well-organized headers. This matches anchor 3 ('some structure; content that should be separate is inline') — above 2 because the section structure is good rather than minimal, below 4 because virtually all detail content belongs in reference files.

Specificity

The description 'Express/Hono with Supabase and Drizzle ORM' is a verbless stack listing: it names the domain but states no concrete actions, matching anchor 2. It is not 3 because no capability ('builds', 'authenticates', 'queries') is expressed at all, and not 1 because the technologies named are specific rather than abstract.

Completeness

The 'what' is vague (a stack, not capabilities) and the 'when' is entirely absent from the description — anchor 2 ('Has a vague what and no when'). Not 1 because the technology scope is explicitly stated; not 3 because anchor 3 requires a clear 'what', which a noun phrase without verbs is not.

Trigger Term Quality

'Express', 'Hono', 'Supabase', and 'Drizzle ORM' are precise terms users would actually say, but coverage is thin — 'Node.js backend', 'Postgres', 'auth', 'REST API' and any synonyms or extensions are missing, matching anchor 3 ('missing common variations or synonyms'). It is above 2 because the present keywords are specific natural terms, not generic filler, and below 4 because more than a few natural trigger phrases are absent.

Distinctiveness Conflict Risk

Naming four specific technologies (Express, Hono, Supabase, Drizzle) carves a distinct niche with minimal conflict risk against unrelated skills — anchor 4. Not 5 because the missing trigger guidance leaves plausible overlap with a generic Supabase or Express skill; not 3 because the stack combination is quite specific.
