Client method surface rules. An agent skill from BuilderIO/agent-native.

  • Works in 3 steps: Look for an existing client API first. → If no client API exists, add the… → Teach the helper, not the route.

What it does

Client Methods is an agent skill from BuilderIO/agent-native. Client method surface rules. Use when wiring browser/client code to actions, application state, framework routes, app APIs, uploads, auth, or settings.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/legacy-client-fetch-audit-2026-06-03.md`).

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

When your agent uses it

  • Wiring browser/client code to actions
  • Application state
  • Framework routes

Example prompts

  • “/client-methods”

Workflow steps

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

  1. Look for an existing client API first.
  2. If no client API exists, add the narrowest helper at the boundary.
  3. Teach the helper, not the route.

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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

    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

Client Methods loads about 1.2k tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 42 tokens; SKILL.md has 491 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.1k

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 491 words (~1,208 tokens).

“Browser/client code imports named methods, hooks, or client modules instead of hand-writing REST calls to framework or app routes.”
