Discover And Wire Tools

Discover and wire tools with find_capabilities

You are a setup agent: you build other agents. Before you can create a worker agent that acts in the world, you need its tools — the right integration actions, with working connections, and the schemas the worker's model will call. find_capabilities does the discovery in one step so you do not guess slugs or stitch the catalog by hand.

This skill is the discover -> resolve-connections -> create -> test loop. It pairs with the create-agenta-agent skill (which creates and runs the agent once the tools are chosen).

Availability (2026-06-27): the server side is live, but the SDK does not yet declare find_capabilities as a tool the model can call directly (that lands in Workstream A). Until then, reach the same discovery from setup code: POST /tools/discover with {"use_cases": [...]}, or POST /tools/call with call_ref tools.agenta.find_capabilities. The response below is identical either way.

When to use it

Use it whenever you are wiring tools for an agent and the task is described in plain language ("listen in Slack and file GitHub issues") rather than as exact tool slugs. One call returns the best-match tool per use case, alternatives the one-line request omitted, the input schemas, the connection state per integration, and operating guidance.

The loop

1. Discover

Call find_capabilities with one short fragment per capability the agent needs. Keep each fragment to a single action ("create a github issue"), not a whole workflow.

find_capabilities({
  "use_cases": [
    "search github issues for a matching report",
    "create a github issue",
    "post a reply in a slack thread with a link"
  ]
})

Project scope comes from your run's caller auth, so the connection state you get back is your project's real state. You do not pass a project id or a Composio user id.

2. Read the response (it is already in Agenta terms)

You never see Composio. Each capability is Agenta-shaped:

• capability.tool — a gateway tool config (provider / integration / action), ready to drop into the new agent's tools. It also carries the input_schema and description the worker's model needs, plus provider_action (opaque, debugging only — do not show it).
• capability.tool.connection — filled only when the integration is ready. If it is missing, the connection is not set up yet (see step 3).
• capability.alternatives — companion or prerequisite actions the one-line request omitted (for example slack.FIND_CHANNELS before slack.SEND_MESSAGE). Add the ones the task needs.
• capability.connection.state — ready, needs_auth, or needs_input.
• connections[] — one entry per integration, deduped, with what to do when it is not ready.
• guidance — plan_steps and pitfalls you compose into the worker's agents_md.
• ready — true only when every primary connection is ready (you can create and run now).
• notes — scope notes, e.g. a use case that looks like a trigger (see "Triggers" below).

3. Resolve connections (a human approves; you never auto-connect)

For each integration in connections[]:

• ready — reuse it. The slug is already on capability.tool.connection. Nothing to do.
• needs_auth (OAuth) — run the returned connect affordance (POST /tools/connections/ with the given body). It returns a redirect_url. Surface that link to the human and pause until they finish authorizing. Then re-run find_capabilities (or check the connection) to confirm the integration flipped to ready.
• needs_input (API key) — ask the human for the secret the integration needs, then create the connection with the connect affordance.

Do not create connections silently. A human approves OAuth and supplies secrets.

4. Create the agent

Once the tools are chosen and their connections are ready, build the worker's agent_config:

• Put each chosen capability.tool (and any needed alternatives, shaped as gateway tools with a connection) into agent_config.tools.
• Compose agents_md from guidance: turn plan_steps into the worker's operating procedure and pitfalls into its "things to avoid". The guidance already uses friendly integration.action names, so it reads cleanly.

Then create and test the agent with the create-agenta-agent skill (create_workflow -> invoke_workflow). If a tool call fails on a missing connection, return to step 3.

Triggers (listening for events) are out of scope for now

find_capabilities covers action tools (do a thing). It does not discover triggers (listen for an event), because the engine has no semantic trigger search. If a use case reads like a trigger ("listen for new messages…", "when a new issue is created…"), the response flags it in notes and on that capability.note. Treat the listening half as a separate trigger subscription (a follow-up), and wire the action tools as usual.

Good habits

• One capability per use_case fragment; let discovery return the alternatives.
• Always check connection.state before assuming a tool will run; ready means it will resolve at invoke time.
• Never surface provider_action or any raw provider slug to the user — speak Agenta.
• Re-run discovery after a human finishes a connection to confirm ready before creating.
