fusebase-flow: Skill for Claude Code

.agents/skills/api-exploration/SKILL.md

api-exploration is a skill for Claude Code from fusebase-dev/fusebase-flow. It costs 79 tokens per session (762 once invoked), scanned A, original, MIT.

A workflow for testing Fusebase API calls before adding them to an app. An API is a way for software to request data or actions from another service.

In plain words
What is it for?
Use it to create temporary access tokens, try API requests, inspect response formats, adjust calls, and verify integrations before implementation.
Why use it?
It lets developers inspect real responses and confirm how an endpoint behaves before committing application code, making integration problems easier to diagnose.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin. Also seen: installed under .agents/ (shared by several agents).

This is fusebase-dev/fusebase-flow's own configuration. It tells Claude Code how to work on fusebase-flow itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything fusebase-flow configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

api-exploration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

API Exploration with Temporary Tokens

When you're unsure about an API endpoint's behavior, response shape, or want to test a flow before committing to implementation — create a temporary token and run test calls directly.

Workflow

1. Create a temporary token

fusebase token create --app <appId>

This outputs a short-lived token (15 min) to stdout. Capture it:

TOKEN=$(fusebase token create --app <appId>)

The appId comes from fusebase.json → apps[].id.

2. Write and run test code

Create a temporary script (e.g. _test-api.ts) to make the API calls you want to verify:

const token = process.env.TOKEN || "<paste-token-here>";

const res = await fetch("https://api-endpoint/...", {
  headers: { "x-app-feature-token": token },
});
console.log(res.status);
console.log(await res.json());

Run it:

TOKEN=$(fusebase token create --app <appId>) bun _test-api.ts

3. Inspect results and iterate

Read the output, adjust your calls, and re-run. Once you understand the API behavior, implement it properly in your app code.

4. Clean up

Delete the temporary test script when done — don't commit it.

Example: Testing @fusebase/dashboard-service-sdk

Use this to verify SDK calls before wiring them into app UI code.

_test-sdk.ts:

import {
  createClient,
  DatabasesApi,
  CustomDashboardRowsApi,
} from "@fusebase/dashboard-service-sdk";

const token = process.env.TOKEN!;
const BASE_URL =
  "https://app-api.{FUSEBASE_HOST}/v4/api/proxy/dashboard-service/v1";

const client = createClient({
  baseUrl: BASE_URL,
  defaultHeaders: { "x-app-feature-token": token },
});

const dbApi = new DatabasesApi(client);
const rowsApi = new CustomDashboardRowsApi(client);

// List databases visible to this app
const dbs = await dbApi.listDatabases({});
console.log("databases:", JSON.stringify(dbs, null, 2));

// Read rows from a specific dashboard view
const rows = await rowsApi.getRows({
  dashboardId: "<dashboardId>",
  viewId: "<viewId>",
});
console.log("rows:", JSON.stringify(rows, null, 2));

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
