What it does

Regenerating Screenshots is an agent skill from Comfy-Org/ComfyUI_frontend. Creates a PR to regenerate Playwright screenshot expectations. Use when screenshot tests are failing on main or PRs due to stale golden images. Triggers on: regen screenshots, regenerate screenshots, update expectations, fix screenshot tests.

Its SKILL.md is about 640 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 Testing & QA, covering Browser testing. It works with Playwright. The repository describes itself as: Official front-end implementation of ComfyUI. The licence is GPL-3.0.

When your agent uses it

  • Screenshot tests are failing on main
  • PRs due to stale golden images
  • : regen screenshots
  • Regenerate screenshots

Example prompts

  • “Use the regenerating-screenshots skill to create a PR to regenerate Playwright screenshot expectations”
  • “/regenerating-screenshots”

Workflow steps

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

  1. Fetch latest main
  2. Create a timestamped branch from origin/main
  3. Create an empty commit
  4. Push the branch
  5. Generate a poem about regenerating screenshots. Be creative — a
  6. Create the PR with the poem as the body (no label yet).
  7. Add the label as a separate step to trigger the GitHub Action.
  8. Report the result to the user

What it can do on your machine

Read from SKILL.md and the folder at commit f9be289. 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

    Shell commands in SKILL.md call:

    • git
    • gh

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

  • Network

    No URLs in SKILL.md. Its commands use git and gh, which can reach the network depending on how they are called.

    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

Regenerating Screenshots loads about 643 tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 228 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~643

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.

Regenerating Playwright Screenshot Expectations

Automates the process of triggering the PR: Update Playwright Expectations GitHub Action by creating a labeled PR from origin/main.

Steps

  1. Fetch latest main

    bash
    git fetch origin main

  2. Create a timestamped branch from origin/main

    Format: regen-screenshots/YYYY-MM-DDTHH (hour resolution, local time)

    bash
    git checkout -b regen-screenshots/<datetime> origin/main

  3. Create an empty commit

    bash
    git commit --allow-empty -m "test: regenerate screenshot expectations"

  4. Push the branch

    bash
    git push origin regen-screenshots/<datetime>

  5. Generate a poem about regenerating screenshots. Be creative — a new, unique poem every time. Short (4–8 lines). Can be funny, wistful, epic, haiku-style, limerick, sonnet fragment — vary the form.

  6. Create the PR with the poem as the body (no label yet).

    Write the poem to a temp file and use --body-file:

    bash
    # Write poem to temp file
# Create PR:
gh pr create \
  --base main \
  --head regen-screenshots/<datetime> \
  --title "test: regenerate screenshot expectations" \
  --body-file <temp-file>

  7. Add the label as a separate step to trigger the GitHub Action.

    The labeled event only fires when a label is added after PR creation, not when applied during creation via --label.

    Use the GitHub API directly (gh pr edit --add-label fails due to deprecated Projects Classic GraphQL errors):

    bash
    gh api repos/{owner}/{repo}/issues/<pr-number>/labels \
  -f "labels[]=New Browser Test Expectations" --method POST

  8. Report the result to the user:

    • PR URL
    • Branch name
    • Note that the GitHub Action will run automatically and commit updated screenshots to the branch.

Notes

  • The New Browser Test Expectations label triggers the pr-update-playwright-expectations.yaml workflow.
  • The workflow runs Playwright with --update-snapshots, commits results back to the PR branch, then removes the label.
  • This is fire-and-forget — no need to wait for or monitor the Action.
  • Always return to the original branch/worktree state after pushing.
