Conciseness

The body is lean with zero padding: it never explains what Zoom, OAuth, or webhooks are, and every line ('Capture the target user flow and success criteria', 'End with the smallest deliverable that proves the architecture') either instructs or defines output. This matches 'Lean and efficient; assumes Claude's competence; every token earns its place'.

Actionability

The workflow names concrete deliverables (auth and scope checklist, delivery phases, architecture summary) but gives no criteria for 'Choose the correct Zoom surface and supporting services' — no list of surfaces (Meetings, Chat apps, Phone), no example scopes, and no commands or templates. This is 'Some concrete guidance but incomplete; missing key details', not 4, because a model executing step 2 has nothing to act on beyond general knowledge.

Workflow Clarity

Six steps in a sensible order (capture requirements → choose surface → auth → phases → risks → minimal deliverable) plus an explicit Output section defining the deliverable, matching 'Clear sequence with most checkpoints present'. It is not 5 because there are no checkpoints at all (e.g. confirm assumptions with the user before drafting phases), and not 3 because the sequence is complete and the final output is unambiguous.

Progressive Disclosure

The ~35-line body is appropriately split into Usage, Workflow, Output, and Related Skills with no content that belongs in a separate file, and cross-references are clearly signaled and one level deep. It is not 5 because every reference (../../README.md and four sibling SKILL.md links) points outside the bundle — none resolve within the skill's own file structure — leaving the README pointer as unverifiable navigation rather than confirmed one-level-deep references.

Specificity

The phrase 'planning Zoom integrations' names a concrete domain but states no capability at all — there is no 'what does this skill do' action, matching the anchor 'Names the domain but actions are minimal or generic'. It is not a 1 because 'Zoom integrations' is a concrete, specific domain rather than the pure abstraction of 'Helps with documents'.

Completeness

The description has an explicit 'when' clause ('Use when planning Zoom integrations') but completely lacks a 'what' — it never states that the skill creates a build plan. This sits between anchor 2 ('only when present without what', e.g. 'Use when working with documents') and anchor 3 ('clear what but when missing'), landing at 3 since the trigger guidance is explicit and the skill's function is at least weakly implied by 'planning'.

Trigger Term Quality

'Use when planning Zoom integrations' includes natural terms ('planning', 'Zoom', 'integrations') a user would say, but misses common variations and synonyms users actually use such as 'Zoom app', 'Zoom API', 'bot', 'meeting', 'OAuth', or 'marketplace', matching 'Some relevant keywords but missing common variations or synonyms'.

Distinctiveness Conflict Risk

'Zoom' carves out a real niche, but the description would also fire for requests handled by closely related sibling skills the body lists (build-zoom-meeting-app, build-zoom-bot, setup-zoom-oauth) since 'planning Zoom integrations' plausibly covers 'build a Zoom bot' — matching 'Somewhat specific but could still overlap with similar skills'.
