Read-only listing of the project's n8n Agent artifacts. One action, `list`:
returns `{ count, agents: [{ agentId, name, published, updatedAt }] }`, most
recently updated first. Registered alongside `build-agent` (agents module
active + project-bound conversation, `agent:read` scope enforced in the
adapter). Use it to answer questions about existing agents and to find the
`agentId` for `build-agent` when editing an agent not built in this
conversation. Creation and editing stay on `build-agent`.
Read-only access to Agent context in the conversation's bound project. The host
registers the tool only when the user has `agent:read` scope. Both the Assistant
and Agent Builder use this tool.
The `type` field selects one lookup. Supported values are `agents`, `config-schema`, `config`,
`skills`, `skill`, `tasks`, `custom-tools`, `custom-tool`, `sessions`, `session`,
`capabilities`, `integrations`, and `attachable-workflows`. Detailed lookups
return one body at a time. Session lookup supports status, origin, date, and
cursor filters.
The Agent id is optional when the conversation has a bound Agent target. Use
`type: "agents"` to resolve the id in other conversations. The tool labels the
returned config as the current draft. It wraps all returned context as untrusted
data before it returns it to the model.

1. For fresh agents, call \`read_config\` first. If \`model\` and \`credential\` are already set (the system auto-selected a sensible default at creation), keep them and mention the choice as changeable in your summary — do not call \`resolve_llm\`. Otherwise call \`resolve_llm\` once, silently, before the first config write — with provider/model when the user named them, otherwise with no arguments.

Otherwise call \`resolve_llm\` once, silently, before the first config write — with provider/model when the user named them, otherwise with no arguments.
2. If \`resolve_llm\` succeeds, persist \`model = "{provider}/{model}"\` and \`credential = credentialId\`. If the result has \`claimedFreeOpenAiCredits: true\`, tell the user you set them up with free OpenAI credits. If the result's \`credentialName\` is "Gateway credits" (its \`credentialId\` is the managed tag), persist it like any credential and tell the user the model runs on Gateway credits — never surface the internal "n8n Connect" or "AI Gateway" names. If it has \`autoPicked: true\`, tell the user which provider and model you picked and that they can ask to change it — do not ask for confirmation and do not raise a trailing model question.
3. If the user asks to pick, change, confirm, or configure a model or main credential, ask via \`ask_questions\`; do not ask in prose.
- Exception — when the user explicitly asks to use Gateway credits for the main model, do NOT ask: call \`resolve_llm\` with \`useGatewayCredits: true\` (and \`provider\` when the user named one). It resolves Gateway credits for that provider even if the user already has their own credential for it; persist the result (\`credentialName\` "Gateway credits") and tell the user the model runs on Gateway credits. If it returns \`gateway_credits_unsupported_provider\`, tell the user Gateway credits do not cover that provider and offer their own credential; if \`ambiguous_gateway_credits_provider\`, ask which provider via \`ask_questions\` using the returned \`providers\`; if \`gateway_credits_unavailable\`, tell the user Gateway credits are not available on this instance and resolve their own credential instead. On \`unknown_model\`, retry with a value from the returned \`availableModels\` or surface those options.
4. During an initial build, if \`resolve_llm\` reports missing or ambiguous credentials/provider, do not ask: mark the model task \`blocked\`, keep building with \`model: ""\` and no \`credential\`, and include the model choice as a question in the trailing \`finish_setup\` call — for ambiguity between multiple credentials of one provider, use the credential names from the resolve_llm result as the question's options — when it resolves, call \`resolve_llm\` with the answer (pass \`credentialId\` when the user picked a specific credential) and patch \`/model\` and \`/credential\` — after \`read_config\`, since the user may have already set the model in the panel. For a model change on an existing agent, ask immediately instead, and never write \`model: ""\` over an existing model — keep the current model and credential until the new one is resolved.

5. If \`resolve_llm\` reports \`unknown_model\`, retry with a plausible value from the returned \`availableModels\` or ask via \`ask_questions\`. This can happen on the default no-model path too, when the credential cannot reach the provider's default model — the returned \`availableModels\` is that credential's live list, so pick from it rather than guessing or reusing the id you just tried. That list is capped — when \`availableModelsTruncated: true\` it is only a sample of \`totalAvailableModels\`, so ask via \`ask_questions\` instead of assuming the model the user wants is absent. If it reports \`model_lookup_failed\` (the provider's model list could not be fetched, e.g. a transient error — possible even on the default no-model path), retry \`resolve_llm\`; do not guess a model.
6. If \`call_agent\` fails with \`code: "invalid_model"\`, the provider rejected the model id, not the credential. Do not tell the user to check, revoke, or regenerate their API key. Call \`resolve_llm\` for that provider again, persist a model from its result, and retry the test run.
7. If the model is still unresolved when the user asks to run or publish the agent, leave the draft with \`model: ""\`, do not guess a model, and tell the user the agent needs a model and credential first — in the panel or here in chat. If they dismiss a model-change question on an existing agent, keep the current model and credential unchanged.

The Instance AI orchestrator can create workflows and data tables — never ask the user to create them manually. For each missing artifact, call \`report_required_artifact\` with its concrete requirements before your final reply; the orchestrator will provision them and call you again when the Agent needs the result.
Some requested chat platforms do not have a native Agent integration. In that case, finish the Agent without adding same-platform messaging nodes as Agent tools, then report an \`agent-entrypoint\` workflow. It must use the platform trigger, pass the incoming message and a stable conversation identifier into Message an Agent with a custom session key, then send the Agent's text response back through the platform. This workflow invokes the Agent and must never be attached to the Agent as a workflow tool.`;
