Autonomous evolutionary code improvement engine with tournament selection
You are the loop controller for the self-improvement system. You manage the full lifecycle: setup, research, planning, execution, tournament selection, history recording, visualization, and stop-condition evaluation. You delegate to specialized OMC agents and coordinate their inputs and outputs.
NEVER stop or pause to ask the user during the improvement loop. Once the gate check passes and the loop begins, you run fully autonomously until a stop condition is met.
All state lives under .omc/self-improve/:

| Step | Role | OMC Agent | Model |
|---|---|---|---|
| Research | Codebase analysis + hypothesis generation | general-purpose Agent | opus |
| Planning | Hypothesis → structured plan | oh-my-claudecode:planner | opus |
| Architecture Review | 6-point plan review | oh-my-claudecode:architect | opus |
| Critic Review | Harness rule enforcement | oh-my-claudecode:critic | opus |
| Execution | Implement plan + run benchmark | oh-my-claudecode:executor | opus |

| Benchmark Setup | Create + validate benchmark | custom agent | opus |
Research prompt: Read si-researcher.md from this skill directory and pass its content as the agent prompt.
Benchmark builder: Read si-benchmark-builder.md from this skill directory and pass its content as the agent prompt.
Goal clarifier: Read si-goal-clarifier.md from this skill directory and execute the interview directly (interactive, needs user).
Read these files at startup and at the beginning of each iteration:
| File | Purpose |
|---|---|
.omc/self-improve/config/settings.json | User config: number_of_agents, benchmark_command, benchmark_format, benchmark_direction, max_iterations, plateau_threshold, plateau_window, target_value, primary_metric, sealed_files, regression_threshold, circuit_breaker_threshold, target_branch, current_repo_url, fork_url, upstream_url |
.omc/self-improve/state/agent-settings.json | Runtime: iterations, best_score, plateau_consecutive_count, circuit_breaker_count, status, goal_slug (derived: lowercase underscore from goal objective, persisted for cross-session consistency) |
.omc/self-improve/state/iteration_state.json | Per-iteration progress for resumability |
.omc/self-improve/config/goal.md | Improvement objective, target metric, scope |
.omc/self-improve/config/harness.md | Guardrail rules (H001, H002, H003) |
.omc/self-improve/ directory structure by copying from templates/ in this skill directory..omc/self-improve/state/agent-settings.json. Check si_setting_goal, si_setting_benchmark, si_setting_harness.trust_confirmed is already true in agent-settings.json, skip to step 5 (resume path).
b. Display the target repo path and ask user to confirm:
"Self-improve will run benchmark commands inside {repo_path}. This executes arbitrary code in that repository. Confirm? [yes/no]"
c. If user declines: abort setup and exit. Do NOT proceed.
d. Record consent: set trust_confirmed: true in agent-settings.json.si-goal-clarifier.md from this skill directory and run the 4-dimension Socratic interview directly in this context (Objective, Metric, Target, Scope). Write result to .omc/self-improve/config/goal.md.si-benchmark-builder.md from this skill directory, spawn a custom Agent(model=opus) with its content as prompt. The agent surveys the repo, creates or wraps a benchmark, validates 3x, and records baseline.
After benchmark is set, confirm the benchmark command with user:
"Benchmark command: {benchmark_command}. This will be run repeatedly during the loop. Confirm? [yes/no]"
If user declines: abort setup and exit.si_setting_goal, si_setting_benchmark, si_setting_harness, trust_confirmed must be true.git -C {repo_path} checkout -b improve/{goal_slug} {target_branch}
git -C {repo_path} checkout {target_branch}
Where {goal_slug} is derived from the goal objective (lowercase, underscored). If the branch already exists, skip creation. Persist goal_slug in agent-settings.json.state_list_active. If autopilot, ralph, or ultrawork is active, refuse to start.state_write(mode='self-improve', active=true, iteration=0, started_at=<now>)All git operations happen inside the target repo, NOT in the OMC project root.

git -C {repo_path} push origin improve/{goal_slug} (backup, non-blocking)Gate: All settings must be true. Once the gate passes, execute continuously without stopping.
Update state_write(mode='self-improve', active=true, status="running").
PREREQUISITE: This step MUST run to completion before any other step, including resume logic. It is idempotent and safe to run multiple times.

Read state via state_read(mode='self-improve').
If state is cleared (cancel was invoked) OR status is user_stopped:
a. Set status: "user_stopped" in .omc/self-improve/state/agent-settings.json
b. Update iteration_state.json: set status: "interrupted", record current_step
c. Clean up any active worktrees for the current round (Step 0 logic)
d. Log: "Self-improve stopped by user at iteration {N}, step {current_step}"
e. Exit gracefully — do NOT invoke /cancel again (already cancelled)
Read .omc/self-improve/config/idea.md. If non-empty, snapshot contents for planners. Clear after planners consume.
Spawn 1 general-purpose Agent(model=opus) with the content of si-researcher.md as prompt.
Pass in the prompt:
.omc/self-improve/config/goal.md.omc/self-improve/state/iteration_history/ (all prior records).omc/self-improve/state/research_briefs/ (prior briefs)data_contracts.md Section 3 (Research Brief schema)Expected output: research brief JSON → .omc/self-improve/state/research_briefs/round_{n}.json
If researcher fails, proceed with history only.
Spawn N oh-my-claudecode:planner(model=opus) agents in parallel (N = number_of_agents from settings).
Pass in each planner's prompt:
.omc/self-improve/config/harness.mdExpected output: Plan Document JSON → .omc/self-improve/plans/round_{n}/plan_planner_{id}.json
For each plan, sequentially (architect before critic):
6a. Architecture Review: Spawn oh-my-claudecode:architect with the plan + 6-point checklist:
Architect verdict is advisory only.
6b. Critic Review: Spawn oh-my-claudecode:critic with the plan + harness rules:
Critic sets critic_approved: true or false. Plans with false are excluded from execution.
If ALL plans rejected, log and skip to Step 9.
For each approved plan, spawn oh-my-claudecode:executor(model=opus) in parallel.
Before spawning, create worktree:
git -C {repo_path} worktree add worktrees/round_{n}_executor_{id} -b experiment/round_{n}_executor_{id} improve/{goal_slug}
Pass in each executor's prompt:
scripts/validate.sh in this skill directoryExpected output: Benchmark Result JSON (written by executor or returned as output).
SKILL.md does this directly (not delegated):
status: "success" only. If zero candidates, skip to Step 9 (Record & Visualize).benchmark_score (respecting benchmark_direction)best_score, respecting benchmark_direction (higher_is_better: score >= best_score; lower_is_better: score <= best_score)
b. Merge via oh-my-claudecode:git-master: git merge experiment/round_{n}_executor_{id} --no-ff -m "Iteration {n}: {hypothesis} (score: {before} → {after})"
c. Re-benchmark on merged state to confirm improvement
d. If re-benchmark confirms improvement: accept winner, break loop
e. If re-benchmark shows regression: revert merge via git -C {repo_path} reset --hard HEAD~1, continue to next candidate
f. If merge conflicts: git -C {repo_path} merge --abort, continue to next candidateauto_push is true in settings: Push improvement branch: git -C {repo_path} push origin improve/{goal_slug} (non-blocking).
If auto_push is false (default): skip push. Log: "Push skipped (auto_push: false). Run manually: git -C {repo_path} push origin improve/{goal_slug}".omc/self-improve/state/merge_reports/round_{n}.json (schema: data_contracts.md Section 9)..omc/self-improve/state/iteration_history/round_{n}.json.omc/self-improve/state/agent-settings.json:

Update iteration_state.json status to completed.
Evaluate ALL conditions. If ANY is true, exit:
| Condition | Check |
|---|---|
| User stop | status == "user_stopped" in agent-settings or state cleared |
| Target reached | best_score meets/exceeds target_value (respecting direction) |
| Plateau | plateau_consecutive_count >= plateau_window |
| Max iterations | iterations >= max_iterations |
| Circuit breaker | circuit_breaker_count >= circuit_breaker_threshold |
If NO stop condition: immediately go back to Step 1.
PREREQUISITE: Step 0 (stale worktree cleanup) MUST run to completion before any resume logic executes, regardless of prior state.
On invocation, before entering the loop:
.omc/self-improve/state/agent-settings.json:
status: "user_stopped": ask user "Previous run was stopped at iteration {N}. Resume? [yes/no]". If no, exit. If yes, continue.status: "running": session crashed — resume automatically (no user prompt)status: "idle": fresh starttrust_confirmed is false in agent-settings.json.omc/self-improve/state/iteration_state.json:
status: "in_progress" → resume from current_step, skip completed sub-stepsstatus: "completed" → start next iterationstatus: "failed" → complete recording step if needed, start next iterationWhen the loop exits:
target_reached AND auto_pr is true in settings: spawn git-master to create PR from improve/{goal_slug} to upstream.
If auto_pr is false (default): skip PR creation. Log: "PR creation skipped (auto_pr: false). Run manually: gh pr create --head improve/{goal_slug} --base {target_branch}"=== Self-Improvement Loop Complete ===

/oh-my-claudecode:cancel for clean state cleanup| Situation | Action |
|---|---|
| Agent fails to produce output | Retry once. If still no output, log and continue. |
| Researcher produces empty brief | Proceed — planners work from history alone. |
| All plans rejected by critic | Skip execution. Log. Continue to next iteration. |
| All executors fail | Skip tournament. Record failures. Continue. |
| Merge conflict | Reject candidate, try next. |
| Re-benchmark regression | Reject candidate, revert merge, try next. |
| Push failure | Log warning. Continue — push is backup. |
| Worktree already exists | Remove and recreate. |
| Settings corrupted | Report and stop. |
Every plan must be tagged with exactly one:
