Motivation

• Orchestrators need a way to know which allowlisted target agents can actually run a requested provider/model before calling sessions_spawn so spawns are routed to capable agents.

Description

• Extend the agents_list tool to accept an optional model parameter and resolve it as either provider-only (e.g. minimax) or full provider/model (e.g. minimax/minimax-m2.5).
• Add requestedModel to the tool response and include each candidate agent's resolved subagentModel in the payload.
• Compute and return capableForRequestedModel for each agent by matching the requested provider/model against the agent's subagent spawn model selection, supporting provider-only checks and model alias resolution.
• Files changed: src/agents/tools/agents-list-tool.ts and test coverage added in src/agents/openclaw-tools.agents.e2e.test.ts (two new tests for exact model and provider-only matching).

Testing

• Ran the e2e test file with pnpm vitest --config vitest.e2e.config.ts src/agents/openclaw-tools.agents.e2e.test.ts and all tests in that file passed (6 passed).
• The new tests exercise full provider/model matching and provider-only capability checks and succeeded.
