What it does

Editor Test Harvester is an agent skill from udecode/plate. Mine external editor repositories for portable editor-behavior tests with ClawSweeper-style discipline: multi-pass exhaustive inventory, confidence scoring, framework-specific skip reasons, Slate/Plate coverage mapping, license-aware invariant extraction, and copy/refactor/create decisions.

Its SKILL.md is about 7.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Rich-text editor with AI and shadcn/ui.

Example prompts

  • “/editor-test-harvester”

Workflow steps

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

  1. The target repo license evidence: LICENSE, LICENCE, COPYING, NOTICE,
  2. The target editor repo, preferably a local checkout like ../lexical.
  3. .tmp/slate-v2 current test files and package scripts.
  4. Plate package/docs/example owners in this checkout when the behavior is a
  5. docs/solutions/ for prior browser, IME, selection, and mobile proof lessons.
  6. .agents/skills/clawsweeper/SKILL.md for issue/PR provenance discipline

What it can do on your machine

Read from SKILL.md and the folder at commit 6f3815d. 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:

    • rg
    • node
    • playwright
    • bun
    • git
    • vitest
    • jest

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • github.com

    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

Editor Test Harvester loads about 7.6k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 2,991 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~7.6k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,991 words (~7,640 tokens).

“Use this skill when mining another editor repository for tests worth harvesting: Lexical, ProseMirror, CodeMirror, Tiptap, Monaco, Quill, or any local clone under ...”
