What it does

Agent HTML is an agent skill from Sayhi-bzb/Agent-HTML. Use when editing AgentHTML artifacts, agent-html files, Gallery Preview DSL, blocks, components, sections, prompt schema, or runtime-rendered artifact content. Before editing AgentHTML content, read .agents/skills/agent-html/references/prompt-schema.md for the current DSL contract and enabled component grammar.

Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/examples.md` and `references/icons.md`).

It sits in Frontend & Design. It works with shadcn/ui. The repository describes itself as: You don't need a chat ui but a canvas with ai. The licence is Apache-2.0.

Requirements

Workflow steps

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

Read .agents/skills/agent-html/references/prompt-schema.md for the supported tags, attrs, defaults, and forbidden constructs.
Reuse the closest valid fixture pattern from .agents/skills/agent-html/references/examples.md before inventing new structure.
Stay within the currently supported runtime tags unless the user explicitly wants a future-target draft.
When an icon is needed, run .agents/skills/agent-html/scripts/search_icons.py "" instead of guessing names.
In an AgentHTML workspace, edit user-facing artifacts at projects/{project-id}/{section-id}/artifact.agent-html.

What it can do on your machine

Read from SKILL.md and the folder at commit 05a16a9. 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/ (Python), 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 no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Agent HTML loads about 523 tokens when it runs, and up to ~8.7k if it reads all its reference files. Until then it costs about 81 tokens; SKILL.md has 195 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~81
When it runs · the whole SKILL.md, loaded when a task matches: ~523
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~8.7k

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.

name: agent-html
description: Use when editing AgentHTML artifacts, agent-html files, Gallery Preview DSL, blocks, components, sections, prompt schema, or runtime-rendered artifact content. Before editing AgentHTML content, read `.agents/skills/agent-html/references/prompt-schema.md` for the current DSL contract and enabled component grammar.

agent-html

Write agent-html DSL, not JSX or HTML.

Workflow

Read .agents/skills/agent-html/references/prompt-schema.md for the supported tags, attrs, defaults, and forbidden constructs.
Reuse the closest valid fixture pattern from .agents/skills/agent-html/references/examples.md before inventing new structure.
Stay within the currently supported runtime tags unless the user explicitly wants a future-target draft.
When an icon is needed, run .agents/skills/agent-html/scripts/search_icons.py "<query>" instead of guessing names.
In an AgentHTML workspace, edit user-facing artifacts at projects/{project-id}/{section-id}/artifact.agent-html.

Rules

Output only agent-html DSL.
Use PascalCase tags.
Root must be <Cell>.
Use quoted scalar attrs like columns="2" or value="82".
Do not use class, className, style, imports, hooks, JS expressions, or raw HTML tags.
Do not invent tags or attrs not present in the grammar reference.
Do not put bare text directly under Cell, Block, Stack, Cluster, or Grid.
Do not put UI directly under Cell or layout nodes; wrap UI in Block, then arrange blocks with layout.
