Quality
Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is an excellent skill description that clearly communicates specific capabilities (screen recording assembly, talk track scripting, branded slides, background music, ElevenLabs voiceover) and provides explicit trigger guidance with natural user phrases. It uses proper third-person voice and is concise yet comprehensive, making it easy for Claude to select this skill appropriately from a large pool.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: building narrated demo video from screen recording, talk track script with act timelines, branded intro/outro slides, background music, and AI-generated voiceover via ElevenLabs. | 3 / 3 |
Completeness | Clearly answers both 'what' (build narrated demo video with specific components like screen recording, talk track, branded slides, music, ElevenLabs voiceover) and 'when' (explicit 'Use when' clause with five trigger phrases). | 3 / 3 |
Trigger Term Quality | Includes excellent natural trigger terms users would actually say: 'demo video', 'product demo', 'narrated screencast', 'talk track video', 'voiceover video'. These cover common variations of how users would phrase this request. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive niche combining screen recording, narrated voiceover, branded slides, and ElevenLabs integration. Very unlikely to conflict with other skills due to the specific combination of video production elements and explicit trigger terms. | 3 / 3 |
Total | 12 / 12 Passed |
Implementation
85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a strong, well-structured skill for a complex multi-step pipeline. It excels in actionability with specific commands, parameters, and file structures, and the workflow is clearly sequenced with validation and iteration steps. The main area for improvement is conciseness — the Script Writing Methodology section, while valuable, is lengthy and some prose could be trimmed without losing clarity.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient but includes some sections that could be tightened — the Script Writing Methodology is quite lengthy and detailed, and some explanations (e.g., 'generic scripts feel dubbed, synced scripts feel alive') are stylistic rather than instructional. However, most content earns its place given the complexity of the pipeline. | 2 / 3 |
Actionability | The skill provides concrete, executable guidance throughout: specific ffmpeg commands, exact API parameters (stability=0.6, similarity_boost=0.8), precise file paths, directory structures, and clear per-segment build instructions with specific audio filter techniques (adelay, aresample, apad, amix). The incremental rebuild instructions are particularly actionable. | 3 / 3 |
Workflow Clarity | The workflow is clearly sequenced across 8 steps with explicit validation (Step 7: verify audio channels, sync drift, music/voice overlap). Step 8 provides a feedback loop for common adjustments with specific instructions on which artifacts to delete and rebuild. The incremental build pattern serves as an effective error recovery mechanism. | 3 / 3 |
Progressive Disclosure | The skill provides a clear overview with well-signaled references to FFMPEG_REFERENCE.md and ELEVENLABS.md for detailed technical content. The main SKILL.md stays at the right level of abstraction for the pipeline while deferring encoding details and API specifics to supplementary files. Internal cross-references (e.g., linking to Script Writing Methodology section) are also well-handled. | 3 / 3 |
