What it does

Actions is an agent skill from BuilderIO/agent-native. How to create and run agent actions. Actions are the single source of truth for app operations — the agent calls them as tools and frontend code calls them through client hooks. Use when creating a new action, adding an API integration, or wiring up frontend data fetching.

Its SKILL.md is about 4.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/action-fields.md`, `references/examples.md` and `references/provider-apis.md`).

It sits in Backend & APIs, covering Third-party API integration. The repository describes itself as: A framework for building agentic apps.

When your agent uses it

  • Creating a new action
  • Adding an API integration
  • Wiring up frontend data fetching

Example prompts

  • “/actions”

What it can do on your machine

Read from SKILL.md and the folder at commit e16da0c. 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:

    • pnpm

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

  • Network

    No URLs in SKILL.md. Its commands use pnpm, 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 no API keys, tokens, secrets or passwords.

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

Context cost

Actions loads about 4.4k tokens when it runs, and up to ~8.8k if it reads all its reference files. Until then it costs about 70 tokens; SKILL.md has 2,162 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~70
When it runs · the whole SKILL.md, loaded when a task matches
~4.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.8k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 2,162 words (~4,403 tokens).

“Actions in actions/ are the single source of truth for app operations. The agent calls them as tools, the frontend calls them through useActionQuery / useActionMutation, and the framework owns the HTTP transport behind those hooks — no duplicate /api/…”
