Quality

Content

71%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is highly actionable with complete runnable examples and a clear sequenced workflow, but it is hurt by repeated boilerplate across sections and by failing to link the existing reference bundle files, leaving them orphaned.

Suggestions

Link the existing reference files (e.g., 'See references/video-extension-implementation.md for full details', 'See references/errors.md for extended error handling') so the bundle is actually used and the body can stay lean.

Factor the shared get_headers() and poll-until-succeed logic into a single helper shown once, then reference it from the Basic Extension and Usage examples to remove the repeated polling boilerplate.

Replace the '# Wait for completion...' placeholder in Basic Extension with an explicit validation checkpoint (poll source task_status to 'succeed' before extending) to close the workflow validation gap.

Dimension	Reasoning	Score
Conciseness	The body is mostly efficient and does not over-explain concepts Claude already knows, but the JWT header construction and the polling loop are repeated across the Basic Extension, Chain, and Usage sections and could be tightened by reuse. Fits score-3 'Mostly efficient but includes some unnecessary... could be tightened'; not 4 because the duplication is noticeable.	3 / 5
Actionability	Provides fully executable, copy-paste-ready Python covering the common cases — single extension, multi-extension chaining, and a 20-second build — with real auth, submission, and polling. Matches score-5 'Fully executable; copy-paste ready code... specific examples cover the common cases'.	5 / 5
Workflow Clarity	Steps are explicitly sequenced (Step 1 generate, Step 2 extend, Step 3 poll) with succeed/failed checkpoints and a raise-on-failure feedback loop in the chain path. Not 5 because the Basic Extension leaves the source-completion wait as a placeholder comment rather than an implemented validation checkpoint.	4 / 5
Progressive Disclosure	Section structure is good, but the bundle files in references/ (errors.md, examples.md, video-extension-implementation.md, etc.) are never referenced or linked from the body, and detailed implementation that could live in those files is inlined instead. Fits score-3 'Some structure... references present but not clearly signaled'; not 4 because the existing references are entirely orphaned.	3 / 5

Description

82%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is well-formed: it states a concrete capability, gives explicit 'Use when' guidance with multiple natural trigger phrases, and occupies a distinct niche. The only weakness is limited action breadth, which is inherent to a single-purpose skill.

Dimension	Reasoning	Score
Specificity	Names the domain ('Kling AI continuation') and a couple of concrete actions ('Extend video duration', 'creating longer videos from shorter clips or building sequences'), but coverage is not comprehensive — it is a single-purpose action. Fits the score-3 anchor 'Names domain and 1-2 concrete actions, but not comprehensive'; not a 4 because it does not list several specific actions.	3 / 5
Completeness	Clearly states what it does ('Extend video duration using Kling AI continuation') and explicitly when to use it ('Use when creating longer videos...') with concrete trigger phrases. Matches the score-5 anchor answering both what AND when with concrete triggers.	5 / 5
Trigger Term Quality	Provides four explicit trigger phrases ('klingai extend video', 'kling ai video continuation', 'klingai longer video', 'extend klingai clip') with synonym variation users would naturally say. Good coverage but a few casual phrasings are missing, so it sits at 4 rather than the comprehensive 5.	4 / 5
Distinctiveness Conflict Risk	Targets a clear niche (Kling AI video extension) with distinct, brand-specific trigger phrases, so conflict with other skills is minimal. Matches the score-5 anchor 'Clear niche with distinct triggers; minimal conflict risk'.	5 / 5
