Conciseness

The body includes concept explanation Claude already knows ("Postman is an API client that makes it easier for developers to develop, test, and document APIs"), filler ("Use action names and parameters as needed."), marketing prose, and a 20-row action table where every row says "No description". The core command reference is efficient, so this is more than minor over-explanation but not severely padded. It is not a 4 because the padding is more than minor, and not a 2 because the actionable core is solid.

Actionability

The body provides copy-paste-ready, fully executable commands for every common case — install, login, connection ensure/get, action list/run, and request proxy — plus a flags table. Specific examples cover the common cases, matching the fully-executable anchor. It is not a 4 because the guidance is complete rather than having minor gaps.

Workflow Clarity

The connection workflow has an explicit state machine with feedback loops: poll until READY, re-poll after the user completes CLIENT_ACTION_REQUIRED, and check the error field on CONFIGURATION_ERROR/SETUP_FAILED. It is not a 5 because steps are not framed as a crisp numbered checklist with explicit 'Validate' steps and the 'skip to Step 2' forward reference has no matching label, and not a 3 because checkpoints are present and explicit rather than missing.

Progressive Disclosure

The skill is self-contained with clear section headers and no broken or nested references, and no bundle files exist to verify. It is not a 5 because at ~160 lines it exceeds the simple-skill threshold and has minor organization gaps (a '#### 1b.' subsection with no '1a', and a 'Step 2' reference without a labeled target), and not a 3 because structure is genuinely good rather than merely present.

Specificity

"Postman integration." names the domain and "Manage Workspaces." gives one concrete action, matching the anchor for naming a domain plus 1-2 actions without comprehensive coverage. It is not a 2 (which requires minimal/generic actions only) nor a 4 (which requires several specific actions).

Completeness

"Postman integration. Manage Workspaces." states what it does and "Use when the user wants to interact with Postman data." gives an explicit when clause, satisfying both. It is not a 5 because the what-side is thin (only Workspaces) and lacks comprehensive concrete trigger phrases, and not a 3 because the when clause is explicit rather than weakly implied.

Trigger Term Quality

"Postman" and "Workspaces" are natural keywords a user would say, but common variations such as collections, APIs, requests, and environments are absent, so coverage is partial rather than good. It does not reach 4 because several common terms are missing, and is above 2 because the core natural phrase "Postman" is present.

Distinctiveness Conflict Risk

"Postman" is a distinct, named application with a clear niche, and the trigger "interact with Postman data" is specific, giving minimal conflict risk with other skills. It is not a 4 because there is no meaningful overlap risk with closely related skills.
