Check that the Cheap Agent server is running and report its version.

Make any code change: use this for every edit, including small, mechanical, "quick" or multi-file ones; those are exactly what the cheap worker is for, and your tokens cost the user far more than its. One call: task = what to change, which files, how to check. The worker edits an isolated worktree, runs the checks, and lands an OK result (uncommitted) in your working tree; read the result block instead of re-checking. Pass difficulty, rated from the issue as the time an engineer new to the code needs to fix and test it: easy < 15 min, medium < 1 h, hard > 1 h. For multi-step work pass plan + steps instead of task. Plan format: one "# " line, then per step a "## " heading followed by "files: ", "do: ", "done-when: " (optional "dont:", "needs: ", "difficulty: easy|medium|hard"), each key at the start of its line, not a bullet. In done-when, backticked text is run as a shell command that must succeed; put only commands in backticks.

Find and explain code in this repository: asks the cheap read-only research worker a question (it reads the working tree, uncommitted changes included). Returns a short answer with path:line refs and a confidence; verify low-confidence answers before acting.

Answer a BLOCKED job's question and resume its worker in the same session. Returns the job's next result block (OK, FAIL, or BLOCKED again); for a job in a batch, the batch block at its next settlement.

List jobs, show a job's last result block again, wait for a job or batch to settle, or cancel a running job (keeps its worktree).

Land or discard finished jobs that did not land (PARTIAL, FAIL, CONFLICT…). apply: 3-way applies a job's worktree changes to your working tree, uncommitted (a conflict leaves the tree untouched); discard: deletes its worktree. One line per job.
