What it does

Design Editor Repro is an agent skill from BuilderIO/agent-native. Reproduce and verify Design editor issues against the application itself.

Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. The skill folder holds 20 other files, including scripts (for example `harness-recipes.md`, `harness/start-dev.sh` and `reference/fixing.md`).

The repository describes itself as: A framework for building agentic apps.

Example prompts

  • “/design-editor-repro”

Requirements

  • Node.js
  • A Bash shell

Workflow steps

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

  1. Start the worktree's Design app with
  2. Run
  3. Copy a source design with
  4. Reproduce the reported steps before changing application code. Save only

What it can do on your machine

Read from SKILL.md and the folder at commit 1c2de07. 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

    Ships 2 files in scripts/ (JavaScript, Swift and Shell), which the agent can run.

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

  • Network

    No URLs in SKILL.md.

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

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • DESIGN_TEST_PASSWORD

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

Context cost

Design Editor Repro loads about 566 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 265 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~23
When it runs · the whole SKILL.md, loaded when a task matches
~566

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); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 265 words (~566 tokens).

“Use this skill for defects that need a real Design editor session. Work from a local or production copy of an Agent-Native design and describe the observed application behavior directly.”
