render-cosmic-mythology-voiceover

Assemble a cosmic-mythology-voiceover reel from a config — a warm spoken voiceover carries the whole narrative while N curated cosmic stills are weighted beat-synced across the delivered VO duration (cut_dur = VO_dur times weight over the weight sum, so emotional beats hold longer), Ken-Burns-zoomed per still (scale 2x, center crop, zoompan, fade-in first and fade-out last), ffmpeg-concatenated, the VO composited under the picture (libx264 crf18 plus aac), the ONE on-screen hook line faded on over the open with a drawtext alpha window, and Whisper/VEED captions burned along the bottom — never in-world text on a still. This is the FREE deterministic assembly stage (weighted sequence plus Ken-Burns plus concat plus VO composite plus hook overlay plus caption burn); the VO and the stills come from create-vo-elevenlabs and create-image-fal. Use for the cosmic-mythology-voiceover format.

Quality

Content

72%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.

An actionable, well-structured skill body with a runnable command, exact formulas, and clean one-level-deep references to real bundle files. It loses points for repeated FREE/deterministic padding and for missing explicit validation checkpoints in a batch render workflow.

Suggestions

Add explicit validation checkpoints to the workflow — e.g. after concat/composite, verify the master is 1080×1920 h264+aac and the delivered VO duration before distributing cuts — to lift workflow_clarity above 3.

Trim the repeated 'FREE, deterministic assembly stage — it spends nothing' phrasing and de-duplicate the Contract section against the description to improve conciseness.

Keep the strong reference structure; optionally surface the render.py arg contract inline as a short table so the body is self-sufficient for the common case.

Dimension	Reasoning	Score
Conciseness	The body is information-dense but repeats the FREE/deterministic emphasis several times ('This is the FREE, deterministic assembly stage — it spends nothing' recurs) and the Contract section restates much of the description; it could be tightened without losing clarity.	3 / 5
Actionability	Provides a copy-paste runnable command with a full arg contract, the exact weighted formula 'cut_dur = VO_dur × weight / Σweights', and concrete ffmpeg/Pillow settings (scale 2×, zoompan, libx264 crf 18, aac 192k) covering the common cases.	5 / 5
Workflow Clarity	The assembly sequence (distribute cuts → Ken-Burns → concat → VO composite → hook overlay → caption burn → endcard) is clear, but this batch media-render workflow lacks explicit validation checkpoints (e.g. verify output is 1080×1920 h264+aac, confirm delivered VO duration before cutting), which caps it at 3 per the destructive/batch guidance.	3 / 5
Progressive Disclosure	The body is a concise overview that clearly signals one-level-deep references — scripts/render.py, scripts/PIPELINE.md, scripts/README.md, scripts/config.example.json (all real files) — with a worked example, giving easy navigation.	5 / 5

Description

83%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.

A highly specific, well-scoped description that names concrete ffmpeg/Pillow/Whisper assembly actions and a distinct format niche. The 'Use for...' clause gives explicit trigger guidance, though it is format-name-only rather than a richer set of natural trigger phrases.

Suggestions

Broaden the 'Use for' clause with a few concrete user-spoken trigger phrases (e.g. 'Use when assembling a faceless cosmic storytelling reel, a myth-voiceover video, or a 9:16 VO-over-stills cut') to lift completeness and trigger-term coverage.

Add common synonyms/medium terms users might say (e.g. 'short-form video', 'spoken-word reel', .mp4) alongside the format name for stronger trigger-term quality.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete assembly actions — 'Ken-Burns-zoomed per still', 'ffmpeg-concatenated', 'composited under the picture (libx264 crf18 plus aac)', 'drawtext alpha window', 'Whisper/VEED captions burned along the bottom' — with comprehensive coverage of the pipeline.	5 / 5
Completeness	Both 'what' (full deterministic assembly) and 'when' ('Use for the cosmic-mythology-voiceover format') are present; the 'when' clause is explicit but terse and format-name-only rather than multiple concrete trigger phrases, so it is not a 5.	4 / 5
Trigger Term Quality	Natural terms for this niche ('cosmic-mythology-voiceover', 'reel', 'voiceover', 'captions', 'stills') are present, but coverage leans on the format name with few synonyms or file extensions a user would naturally say.	4 / 5
Distinctiveness Conflict Risk	The named 'cosmic-mythology-voiceover' format is a narrow, well-defined niche with distinct triggers and minimal overlap risk with other skills.	5 / 5
