Should launch docker-agent use its own session store? My first thoughts are that it shouldn't.
I ran into something while manually testing.
Docker Agent can end up installed twice. Docker Desktop bundles it as a CLI plugin, and it's also available via brew install docker-agent. Both share ~/.cagent/session.db, and its schema migrations appear to be one-way: after I ran a newer build once, the Desktop-bundled one refused to start at all "session database was created by a newer version ...supports migrations up to 21, but the session database has migration 30".
find_docker_agent falls back to ~/.docker/cli-plugins, so llmman resolved to that same plugin, and the error surfaced as an llmman launch docker-agent failure even though llmman wasn't involved in the migration.
I resolved it with rm ~/.cagent/session.db.
docker-agent has a --data-dir flag that would give llmman its own store, though that would also keep llmman runs out of the user's docker agent sessions history.
Is that worth guarding against, or is sharing the user's session store is the behaviour we'd expect here?

Fit every E2E matrix job within 360 minutes.
The budgets are sequential within a job, not aggregate across matrix jobs. A macOS arm64 job can reach the documented 560-minute total. Linux jobs can reach 550 minutes, and Windows jobs retain a 400-minute launch-suite budget. The hosted-runner limit can cancel each slow job at 360 minutes. Reduce the serialized retry budget or split the E2E suite.

Use a separate agent file for each launch.
launch_docker_agent always writes agent.yaml. write_atomic prevents partial reads, but it does not prevent one launch from replacing the file used by another launch. The first Docker Agent can therefore read the second launch's model and endpoint while retaining the first launch's LLMMAN_API_KEY environment.
Generate a unique file for each launch. Remove the file after the Docker Agent child exits.

Thanks! Two things:
- A launched agent with no toolsets can't do much. Instead, merge system messages into one leading message in
/v1/chat/completions, like/v1/messagesand/v1/responsesalready do. Then generate the agent withshell+filesystemtoolsets and drop the README workaround. - CI downloads the docker-agent binary without checking it. Pin and verify a sha256 per asset, the same way the AGY install does.
Moving to draft for now. Please mark it ready for review again when these are done.

Hi @HassanBahati, Yes the DB upgrade strategy doesn't support downgrades and different docker agent versions cannot work together. DB schema upgrades aren't frequent but still can happen. |
