Conciseness

Mostly efficient and specific to PostHog endpoints without explaining basics Claude already knows, though a few passages (the materialised-limit roadmap note, the speculative pricing note, the full example interaction) are conversational padding that could be trimmed.

Actionability

Fully executable guidance throughout: exact endpoint URL, Authorization header, sample JSON payload, per-language generator commands, an error-status table with handling, and a copy-paste-ready example call.

Workflow Clarity

A clear 7-step Workflow with a verification checkpoint (optionally call 'endpoint-run' to confirm the payload works); error-recovery guidance lives in the error table rather than as explicit feedback loops inside the steps, leaving a minor gap.

Progressive Disclosure

Well-organized with clear section headers, but as a single ~228-line file with no bundle references, advanced detail (rate-limit bucket numbers, pricing forecasts, CLI subcommands, the full example interaction) is inlined that could be split into one-level-deep reference files.

Specificity

Lists multiple concrete actions — 'fetching the OpenAPI spec, generating a typed client', 'sending the right auth header', 'shaping the variables payload', 'handling rate-limit and materialised-endpoint error responses' — with comprehensive coverage of the caller-side task.

Completeness

Explicitly answers both what (wire a PostHog endpoint into a client app/SDK with spec, client gen, auth, payload, errors) and when (concrete 'Use when the user says...' trigger phrases).

Trigger Term Quality

Includes natural user phrases ('how do I call my endpoint', 'generate a client for this', 'what auth header do I use') that users would actually say, though a few synonymous trigger terms (e.g. 'client SDK', 'TypeScript client') are absent.

Distinctiveness Conflict Risk

Occupies a clear niche as the caller-side counterpart to 'creating-an-endpoint', with distinct triggers and materialised/HogQL specifics that minimize overlap with other skills.
