70%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
The body is highly actionable with well-sequenced workflows, explicit validation steps, and strong error-recovery loops, and its references are real and clearly signaled. However, it is noticeably bloated: the internal SOP is stated twice in the body and duplicated again in references/internal-sop.md, ffmpeg parameter explanations re-teach known concepts, and extensive troubleshooting/HLS detail belongs in reference files. A pinned yt-dlp version (2025.10.22) is also time-sensitive without a deprecation framing.
Suggestions
Remove the duplicate "Reliable Download SOP (Internal)" and "Agent Execution Checklist (Internal)" sections from SKILL.md and keep a single pointer to references/internal-sop.md, retaining only the checklist items that add new information.
Move the detailed Troubleshooting Quick Reference and HLS Stream Downloads sections into reference files (e.g., references/troubleshooting.md, references/hls.md), keeping only the top-level decision guidance and one example command in SKILL.md.
Drop the ffmpeg "Parameters explained" list (Claude knows libx264/crf/preset semantics) and reframe the pinned yt-dlp version (2025.10.22) as a minimum-version note or move it to the PO token setup reference to avoid time-sensitivity penalties.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The internal SOP appears twice in the body ("Reliable Download SOP (Internal)" and "Agent Execution Checklist (Internal)" repeat the 403/PO-token/WPC/proxy guidance) and a third time nearly verbatim in references/internal-sop.md; ffmpeg flag explanations ("-crf 23: Constant Rate Factor for quality (18-28 range, lower = better quality)") teach concepts Claude already knows. Not 3: this is substantial triple redundancy plus padded explanation sections, not just occasional slack — several sections could be deleted outright with no information loss. | 2 / 5 |
Actionability | Copy-paste-ready yt-dlp, ffmpeg, and ffprobe commands throughout (e.g., "yt-dlp -f \"bestvideo[height<=1080]+bestaudio/best\" \"VIDEO_URL\"\"", the ffmpeg -headers HLS invocation with protocol_whitelist) plus a complete argument reference for scripts/download_video.py covering the common cases. Not 4: even edge cases like separate audio/video stream merging and exact error-string matching ("Extracting cookies from chrome" hangs) are fully specified. | 5 / 5 |
Workflow Clarity | Default flow (steps 1–5), PO token setup with a verification step ("Run yt-dlp -F again. Look for formats 137 (1080p), 271 (1440p), or 313 (4K)"), and quality verification via ffprobe give explicit validation; troubleshooting sections provide feedback loops (403 → fix headers → retry, PO token timeout → restart once → retry) and a checklist for complex provider fallback. Not 4: validation checkpoints and error-recovery loops are explicit at every stage, including confirmation before batch playlist downloads. | 5 / 5 |
Progressive Disclosure | References (references/text-first.md, references/po-token-setup.md, references/internal-sop.md) are real, one level deep, and clearly signaled ("Further Reading", "follow references/text-first.md FIRST"), but ~400 lines of troubleshooting, HLS workflow, and WebM-conversion detail are inlined in SKILL.md, and the SOP content is duplicated into the body instead of being split out. Not 4: content that clearly belongs in separate files sits inline and is duplicated, which is more than a minor organization gap; not 2 because navigation and signaling are genuinely good. | 3 / 5 |
