What it does
App Authoring is an agent skill from OtoDock/oto-dock. Authoring contracts for interactive artifacts, app dashboards, and Dock panels — displayui backchannel and theme events, pinapp action buttons (firetask / sendprompt / mcptool / platform, per-action minrole), live data panels, the platform catalog (otodock.feed / otodock.platform), live apps (appstate / apppush / openapp), releases and rollbackapp, what a shared app or link viewer sees, scoped dashboards, file pins, and apps with a server — the folder contract, handlers the platform wakes, bindings between apps…
Its SKILL.md is about 23k tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files (for example `templates/booking/app.json`, `templates/booking/server/index.ts` and `templates/kanban/app.json`).
It sits in Agent Workflows, covering MCP servers. The repository describes itself as: The agentic company OS. The brains of your company, built on Claude Code and Codex, working on your Anthropic and OpenAI subscriptions.
When your agent uses it
- Updating a displayui artifact
- Tasks that involve MCP servers
Example prompts
- “/app-authoring”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit 5308f5a. 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 script files (TypeScript), which the agent can run.
Shell commands in SKILL.md call:
curl
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use curl, 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 these keys or tokens, usually read from environment variables:
OTODOCK_APP_TOKENOTODOCK_STEP_TOKENSTRIPE_SECRET_KEYSTRIPE_WEBHOOK_SECRETOTODOCK_APP_PUBLIC_KEYPROXY_API_KEYGH_TOKENSMTP_PASSWORD
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
App Authoring loads about 23k tokens when it runs. Until then it costs about 166 tokens; SKILL.md has 12,675 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); 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 12,675 words (~22,593 tokens).
“The display-tools skill covers WHEN to reach for these surfaces; this one is the full authoring reference. Everything here renders in the same sandboxed, theme-matched frame (token vars, primitives, and kit script tags are listed on the display_ui tool itself).”
