Summary by CodeRabbit

  • New Features
    • Chat requests can now be processed through configured agents and return OpenAI-compatible completions.
    • Agent sessions are preserved across requests for more consistent conversations.
    • Agents can use isolated runtimes with configurable models and credentials.
  • Bug Fixes
    • Replaced the previous “not implemented” response with working chat completion support.
    • Added structured error responses for missing agents, startup failures, unavailable runtimes, request failures, and timeouts.
  • Tests
    • Expanded coverage for successful requests, configuration, missing agents, and runtime or adapter errors.

📝 Walkthrough

Walkthrough

The agent-model API now executes authorized chat requests through isolated per-agent OpenCode servers. It reuses sessions, handles runtime and adapter failures, applies execution timeouts, and returns OpenAI-compatible completions. Tests cover success, configuration, missing agents, validation, and adapter errors.

Changes

Agent model execution

Layer / File(s) Summary
Per-agent OpenCode lifecycle
tinyagentos/taos_agent_runtime.py
Creates or reuses an isolated OpenCode server per agent and model. Stores session state and safely stops outdated or existing servers.
Chat endpoint execution and validation
tinyagentos/routes/agent_model_api.py, tests/test_routes_agent_model_api.py
Resolves agents by name or ID, executes the latest message through the adapter, applies timeout handling, accumulates streamed output, and returns structured errors or OpenAI-compatible completions. Tests cover the updated behavior.

Closing per the card's own rules, without prejudice to the content: tsk-gkh4mi explicitly requires a live round-trip against a real deployed agent pasted in the PR ("a passing unit test alone is NOT sufficient evidence") and says to release the card rather than open an unverified PR — no such evidence is here. The required doc sweep (agent-coordination + agent-manual) and CHANGELOG are also absent. And this card is already being worked in open PR #2195 (hognek, currently blocked on 4 review findings + a rebase) — two PRs building the same slice is the collision class; #2195 has seniority. If #2195 stalls permanently, this branch can be revisited as a fix-forward base. Dispatch is globally paused (bus 2295) pending the dispatcher guard fixes; the double-offer of a PR-guarded card is now also recorded on tsk-5ypylc.

A list can contain non-object values. messages[-1].get(...) then raises inside _drive, and the client receives a 500 response for an invalid request. The adapter also requires text content.

Validate that the final message is an object with string content, then return the existing 400 envelope when it is not.

Authorize the resolved agent ID, not a colliding name.

The consent binding authorizes agent_ids, but this function resolves a matching name before a matching ID. If one agent name equals another agent ID, a key consented for the ID can execute the named agent instead.

Resolve by ID first and reject ambiguous aliases. If name aliases remain supported, verify that agent["id"] is in the consent binding after resolution.

Close the adapter on every exit path.

adapter.close() only runs after a successful prompt(). A session-creation error, a prompt exception, or task cancellation skips it. Each failed request can retain an httpx client and its connections.

Move await adapter.close() into a finally block in _drive().

Serialize lifecycle changes for each agent.

Two requests for the same agent can both observe an unavailable server during startup. The second request can replace the first server while its ensure_running() call is suspended. Both instances can then attempt to bind the same stable port.

Use a per-agent asyncio.Lock that covers lookup, replacement, state-map updates, and ensure_running().

Restore the health check before reuse.

is_running() only checks whether the child process has exited. It does not check whether OpenCode accepts requests. This early return bypasses ensure_running(), so a live but unhealthy server remains cached and turns fail instead of restarting it.

Remove the early return. Call await server.ensure_running(...) for both new and matching cached servers.

Do not use the LiteLLM master key for an agent server.

When llm_key is absent, this assigns the installation master key to the OpenCode configuration. That key can perform LiteLLM admin operations, including virtual-key management. An agent runtime must receive only its scoped virtual key.

Provision a restricted per-agent key, or reject agent configurations that do not provide one.

Sanitize agent_id before using it in the OpenCode home directory.

ensure_agent_opencode_server() interpolates agent_id into home, and there is no path-safety guard. If agent_id contains / or .., the OpenCode home can be moved outside data_dir; an absolute agent_id makes data_dir ineffective. Derive the directory name from a stable hash and normalize before server startup.

SUGGESTION: Missing password falls back to empty string

If opencode_server_passwords exists but lacks the model key (e.g., in tests or after manual state mutation), the empty-string password silently reaches OpenCodeConfig and causes an opaque auth failure. Consider raising or generating the missing password here to fail fast.

WARNING: Failed server remains in app_state before ensure_running completes

The server object is stored in app_state.opencode_servers at line 224, but await server.ensure_running(deadline_s=180.0) at line 229 may raise. On the next request for the same agent, the stale object is retrieved; is_running() returns False, stop() is attempted (and may also fail silently), and a new server is created — leaking the old one if it partially started.


Reply with @kilocode-bot fix it to have Kilo Code address this issue.

except Exception:
logger.debug("taos_agent_runtime: error during agent server stop", exc_info=True)
finally:
servers.pop(agent_id, None)

WARNING: stop_agent_opencode_server leaves stale entries in related dicts

servers.pop(agent_id) and session_ids.pop(agent_id) are cleaned up, but opencode_server_passwords, opencode_server_keys, and opencode_server_models retain the agent's entries. Future calls may reuse the stale password/model instead of regenerating, or the leaked key persists in memory after the server is gone.
