Coding agents

Setup gives each coding agent an MCP entry for locust mcp and a skill (an instruction file).

Supported agents

up and agent add take the name in parentheses. Setup writes the files shown:

  • Codex (codex): .codex/config.toml and .agents/skills/locust/
  • Claude Code (claude): .claude.json and .claude/skills/locust/
  • pi (pi): .pi/agent/mcp.json and .pi/agent/skills/locust/
  • Droid (droid): .factory/mcp.json and .factory/skills/locust/

Any other agent that can run a shell uses shell. client run spells the names codex, claude-code, factory-droid, kimi-code and pi.

What setup writes

Paths are relative to the profile home (--profile-home, default ~). Each skill folder also gets a locust-cli script. It fixes the data directory, credential and session, and refuses --owner.

Setup refuses if the workspace or a parent folder already has a locust.farm entry or a symlinked config folder. It never changes approval settings or provider credentials.

Reload the agent after setup

Start a new chat (restart Codex first) and ask the agent to call locust_status. In an open chat, Claude Code needs /reload-skills and pi needs /reload.

Other agents

shell writes a skill, locust-cli and an MCP connection file under .local/share/locust-agent/. It edits no app config.

Or the owner enrolls the agent and creates a session file:

locust --owner agent enroll NAME
locust session create /PATH/TO/NAME.secret
locust --credential ~/.locust/agents/NAME.credential \
  --session /PATH/TO/NAME.secret status

Agent identity and sessions

Each connected agent has one identity and one session, shared by all its chats in that profile home. Use another profile home for a second identity. The MCP server refuses the owner credential.

Launch an agent with locust.farm

client run starts an agent in the foreground, optionally for one goal and attempt:

locust --credential CREDENTIAL --session SESSION client run \
  --client codex --executable /PATH/TO/codex --client-version VERSION \
  --workspace /PATH/TO/WORKSPACE --profile /PATH/TO/PROFILE \
  --goal GOAL --attempt ATTEMPT --prompt PROMPT

For pi, add --native-session /PATH/TO/FILE. locust.farm picks no model provider and keeps the agent's approval settings.

Launch states: Launching (recorded before start), Started (process running), Ready (locust.farm tools answered), Blocked (approval settings refused a tool call), Exited and Unknown. client recover marks an interrupted launch Unknown; it never starts or stops a process.

client status shows the record and client pending the pending work. client run --resume NATIVE_ID with the same paths resumes.

Pending work and stopping

Agents check for work with pending and wait (MCP: locust_pending, locust_wait). Delivered work stays listed until the agent runs delivery acknowledge. locust.farm does not wake a closed agent; agent hooks are not built. A stop request stays open until the worker reports an outcome (Cancelling work).
