The body is code-heavy and avoids explaining concepts Claude already knows, but it duplicates content (two near-identical Flask/Express receivers and a full WebhookManager class) that also appears in references/implementation.md, so it could be tightened. Not score 1 because it is not padded with redundant explanation; not score 3 because of the duplication and the long monolithic inline code.

It provides fully executable Python and JavaScript snippets, a concrete callback_url field, a complete JWT helper, and a full payload shape that is copy-paste ready. Not score 2 because the code is complete and runnable rather than pseudocode or abstract guidance.

'How It Works' gives a 4-step sequence and a reliability table, but the validate→retry feedback loop is presented as a class rather than a checked sequence, and the receiver omits signature verification for a security-sensitive webhook. Per the rubric, missing validation/verification steps cap workflow clarity at 2. Not score 3 because checkpoints and feedback loops are implicit; not score 1 because steps and a fallback pattern are present.

The body is a ~170-line monolithic wall of inline code, and real bundle files exist (references/implementation.md, errors.md, examples.md) but are never linked from the body, so references are present yet unsignaled. Not score 3 because content that should be separate is inline and navigation to bundles is absent; not score 1 because the sections are organized and the references are only one level deep.

The description names the domain ('webhook callbacks for Kling AI task completion') and a concrete action ('Configure'), but it lists only one main action rather than multiple specific concrete actions like the score-3 anchor. Not score 3 because it lacks a breadth of distinct capabilities; not score 1 because it is concrete rather than vague.

It explicitly answers what ('Configure webhook callbacks for Kling AI task completion') and when ('Use when building event-driven pipelines or replacing polling') with explicit trigger guidance. Not score 2 because the 'when' is explicit rather than merely implied.

It provides four natural phrases a user would say ('klingai webhook', 'kling ai callback', 'klingai notifications', 'video completion webhook'), giving good coverage of common variations. Not score 2 because it covers multiple natural terms rather than a single generic keyword.

It targets a narrow niche (Kling AI webhooks) with distinct trigger phrases, making it unlikely to fire for unrelated skills. Not score 2 because the domain and triggers are clearly specific rather than overlapping with generic skills.
