avatar-video

Create AI avatar videos with precise control over avatars, voices, scripts, scenes, and backgrounds using HeyGen's v2 API. Use when: (1) Choosing a specific avatar and voice for a video, (2) Writing exact scripts for an avatar to speak, (3) Building multi-scene videos with different backgrounds per scene, (4) Creating transparent WebM videos for compositing, (5) Using talking photos as video presenters, (6) Integrating HeyGen avatars with Remotion, (7) Batch video generation with exact specs, (8) Brand-consistent production videos with precise control.

Quality

Content

87%

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

A well-structured, concise, actionable skill body with strong progressive disclosure and a clear default workflow. The main gap is missing explicit validation checkpoints for batch and destructive operations.

Suggestions

Add an explicit validation checkpoint to the workflow before generation (e.g., verify avatar_id and voice_id exist via GET /v2/avatars and /v2/voices before POST /v2/video/generate) rather than only mentioning it as a best practice.

For batch generation, include a confirmation/quota-check step (e.g., check credits via references/quota.md) before issuing multiple POST /v2/video/generate calls.

For the delete_video operation, add an explicit confirm-before-delete checkpoint to satisfy the destructive-operation feedback-loop requirement.

DimensionReasoningScore

Conciseness

Lean and efficient: each section earns its place with no padding explaining what avatars/voices/MCP are, and detailed material is offloaded to reference files rather than inlined.

3 / 3

Actionability

Provides an executable curl example with the real X-Api-Key header and endpoint, exact HTTP methods/paths in the workflow, and concrete tool names in the selection table; best practices cite specific fields like test: true and preview_image_url.

3 / 3

Workflow Clarity

The Default Workflow is a clear numbered 5-step sequence with endpoints and a polling termination condition, but destructive (delete_video) and batch operations named by the description lack explicit validation checkpoints, which caps this dimension at 2 per the rubric.

2 / 3

Progressive Disclosure

Overview body points to one-level-deep references; both 'Quick Reference' and 'Reference Files' tables map tasks to markdown links, and all 15 referenced files verified to exist with clear organization by category.

Description

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.

A strong, third-person description that pairs a concrete capability statement with an explicit, multi-trigger 'Use when' clause covering the skill's distinct use cases.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — choosing a specific avatar and voice, writing exact scripts, multi-scene videos with different backgrounds, transparent WebM, talking photos, and Remotion integration — rather than vague language.

3 / 3

Completeness

Explicitly answers both what ('Create AI avatar videos with precise control over avatars, voices, scripts, scenes, and backgrounds using HeyGen's v2 API') and when ('Use when:' with eight numbered triggers).

3 / 3

Trigger Term Quality

Uses natural phrasings a user would actually say: 'specific avatar and voice', 'exact scripts', 'transparent WebM', 'talking photos', 'Remotion', and 'batch video generation'.

3 / 3

Distinctiveness Conflict Risk

The 'precise control' framing and HeyGen v2 specificity carve a clear niche unlikely to trigger for the wrong skill; the body even contrasts it against a sibling 'create-video' skill.
