What it does

Character Animation QA is an agent skill from calesthio/OpenMontage. Review local character animation with schema checks, Playwright browser previews, frame sampling, and FFmpeg/ffprobe final output checks.

Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Media & Creative, covering Video production and Browser testing. It works with FFmpeg and Playwright. The repository describes itself as: World's first open-source, agentic video production system. 12 production pipelines, 100+ tools, 700+ agent skill and production-knowledge files. Turn your AI coding assistant… The licence is MIT.

When your agent uses it

  • Tasks that involve Video production
  • Tasks that involve Browser testing

Example prompts

  • “/character-animation-qa”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Schema validation: character design, rig plan, pose library, action timeline.
  2. Static asset checks: referenced parts and backgrounds exist.
  3. Browser preview: load the preview, capture screenshots, collect console errors.
  4. Motion check: compare sampled frames for non-trivial differences.
  5. Final MP4 check: ffprobe metadata, duration, resolution, audio, frame samples.
  6. Agent visual review: inspect sampled frames for detached limbs, bad layers,

What it can do on your machine

Read from SKILL.md and the folder at commit 9327439. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • playwright.dev
    • ffmpeg.org

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Character Animation QA loads about 389 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 126 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~40
When it runs · the whole SKILL.md, loaded when a task matches
~389

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Character Animation QA

Use this skill before presenting a character-animation preview or final render.

Review Layers

  1. Schema validation: character design, rig plan, pose library, action timeline.
  2. Static asset checks: referenced parts and backgrounds exist.
  3. Browser preview: load the preview, capture screenshots, collect console errors.
  4. Motion check: compare sampled frames for non-trivial differences.
  5. Final MP4 check: ffprobe metadata, duration, resolution, audio, frame samples.
  6. Agent visual review: inspect sampled frames for detached limbs, bad layers, off-frame characters, unreadable expressions, broken text.

Playwright Pattern

ts
const browser = await chromium.launch();
const page = await browser.newPage({ viewport: { width: 1280, height: 720 } });
await page.goto(previewUrl, { waitUntil: "networkidle" });
await page.screenshot({ path: "preview.png" });

Pass/Revise/Fail

  • pass: technical checks pass, acting is readable.
  • revise: fixable rig/timeline issue.
  • fail: missing assets, blank render, runtime failure, or wrong runtime.
