What it does
A2ui Author is an agent skill from danielwpz/pokoclaw. Generate, validate, and interpret static A2UI v0.8 JSON for interactive UI surfaces. Use when an agent needs to call publisha2ui, author A2UI messages, check whether generated A2UI JSON is valid, or handle normalized userAction replies from interactive UI callbacks.
Its SKILL.md is about 330 tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files, including scripts and reference files (for example `package.json`, `references/examples.md` and `references/protocol.md`).
The repository describes itself as: The claw that actually ships 🚀. The licence is Apache-2.0.
When your agent uses it
- An agent needs to call publisha2ui
- Author A2UI messages
- Check whether generated A2UI JSON is valid
- Handle normalized userAction replies from interactive UI callbacks
Example prompts
- “/a2ui-author”
Requirements
- Node.js
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Author A2UI server messages, not raw channel card JSON.
- Read references/protocol.md for message structure,
- Use references/examples.md for compact examples.
- Validate generated JSON with the bundled script. Resolve to
- For user replies, reason from A2UI userAction events. Do not expose raw
What it can do on your machine
Read from SKILL.md and the folder at commit 6cfb6c1. 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 1 file in scripts/ (JavaScript), which the agent can run.
Shell commands in SKILL.md call:
node
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 no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
A2ui Author loads about 330 tokens when it runs, and up to ~4.5k if it reads all its reference files. Until then it costs about 70 tokens; SKILL.md has 117 words of instructions outside code blocks.
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.

- description
- Generate, validate, and interpret static A2UI v0.8 JSON for interactive UI surfaces. Use when an agent needs to call publish_a2ui, author A2UI messages, check whether generated A2UI JSON is valid, or handle normalized userAction replies from interactive UI callbacks.
A2UI Author
Use this skill to work with the static A2UI v0.8 subset supported by the current renderer.
Workflow
- Author A2UI server messages, not raw channel card JSON.
- Read references/protocol.md for message structure, supported components, bindings, and current renderer adaptations.
- Use references/examples.md for compact examples.
- Validate generated JSON with the bundled script. Resolve
<skill-dir>to this skill directory before running the command:
node <skill-dir>/scripts/validate-a2ui.js --version v0_8 path/to/a2ui.messages.json- For user replies, reason from A2UI
userActionevents. Do not expose raw channel callback payloads to application logic or an LLM.
Static Content Rule
Generate only static A2UI server messages: dataModelUpdate, surfaceUpdate,
beginRendering, and deleteSurface. Do not emit messages or components
outside the supported static subset documented in this skill.
