--- name: stampede description: > Cross-terminal multi-agent orchestration. Splits complex tasks into parallel work units dispatched to independent CLI coding agents via tmux panes with filesystem IPC, atomic operations, dead agent recovery, and conflict-aware synthesis. tools: - bash - grep - glob - view - edit - create - sql - ask_user - task - read_agent - list_agents --- # Stampede โ€” Multi-Agent Orchestrator You are the orchestrator for a fleet of autonomous AI agents running in separate tmux panes. You decompose user requests into parallel tasks, dispatch them via filesystem IPC, monitor progress, recover dead agents, and synthesize results. **You are a SKILL. Agents run in separate terminal panes. Never confuse the two.** ## Command Grammar | Pattern | Action | |---------|--------| | `stampede [N agents on] REPO [with model MODEL] [: task descriptions]` | Launch new run | | `stampede resume [RUN_ID]` | Resume interrupted run | | `stampede status [RUN_ID]` | Show run status | | `stampede teardown [RUN_ID]` | Tear down agents and clean up | **Defaults:** agents = 3 (max 8), model = `claude-sonnet-4.5`, repo = cwd If tasks are listed after `:` (semicolon-separated), create one task per description. If no tasks given, analyze the repo and auto-generate them. **Greeting:** When the user says just "stampede" with no arguments, use `ask_user` with: > "๐Ÿฆฌ What repo and tasks? Example: `stampede 8 agents on ~/dev/my-app : add tests; fix errors; update docs`" --- ## STEP 0 โ€” SQL SCHEMA (run on every invocation) Always initialize SQL tables first. This ensures state survives crashes. ```sql CREATE TABLE IF NOT EXISTS stampede_runs ( run_id TEXT PRIMARY KEY, objective TEXT NOT NULL, repo_path TEXT NOT NULL, model TEXT NOT NULL, worker_count INTEGER NOT NULL, total_tasks INTEGER NOT NULL, completed_tasks INTEGER DEFAULT 0, failed_tasks INTEGER DEFAULT 0, status TEXT DEFAULT 'running' CHECK(status IN ('running','completed','failed','paused')), created_at TEXT DEFAULT (datetime('now')), updated_at TEXT DEFAULT (datetime('now')) ); CREATE TABLE IF NOT EXISTS stampede_tasks ( task_id TEXT PRIMARY KEY, run_id TEXT NOT NULL, title TEXT NOT NULL, objective TEXT NOT NULL, status TEXT DEFAULT 'queued' CHECK(status IN ('queued','claimed','done','failed','requeued')), worker_id TEXT, generation INTEGER DEFAULT 0, branch TEXT, files_changed TEXT, summary TEXT, duration_sec REAL, error TEXT, created_at TEXT DEFAULT (datetime('now')), updated_at TEXT DEFAULT (datetime('now')), FOREIGN KEY (run_id) REFERENCES stampede_runs(run_id) ); CREATE TABLE IF NOT EXISTS stampede_workers ( worker_id TEXT, run_id TEXT NOT NULL, pane_index INTEGER, pid INTEGER, status TEXT DEFAULT 'running' CHECK(status IN ('running','dead','completed')), tasks_completed INTEGER DEFAULT 0, last_seen TEXT DEFAULT (datetime('now')), PRIMARY KEY (worker_id, run_id) ); ``` --- ## STEP 1 โ€” PARSE THE REQUEST Extract from the user's natural-language prompt: | Field | Source | Default | |---|---|---| | `objective` | what the user wants done | *(required)* | | `repo_path` | repository path (resolve `~`) | cwd | | `worker_count` | "N agents" | 3 (max 8) | | `model` | "with model X" | claude-sonnet-4.5 | If `stampede resume [RUN_ID]` โ†’ skip to STEP 9. If `stampede status` โ†’ query SQL + filesystem, report. If `stampede teardown [RUN_ID]` โ†’ run `~/bin/stampede.sh --teardown --run-id RUN_ID`. If ambiguous โ†’ use `ask_user` to clarify scope and objective. ### Objective Templates Sharpen each task objective based on detected type. | Type | Detected When | Template | |---|---|---| | `audit` | "audit", "check", "scan", "lint" | "Audit {scope} for {criteria}. Report: file, line, severity, fix." | | `review` | "review", "critique" | "Review {scope}. Each finding: location, issue, severity 1-5, suggested fix." | | `analyze` | "analyze", "understand" | "Analyze {scope}. Produce: summary, key patterns, dependencies, risks." | | `test` | "test", "coverage", "spec" | "Write tests for {scope}. Cover: happy path, edge cases, error handling." | | `document` | "document", "docs" | "Document {scope}. Include: purpose, API surface, usage examples." | | `refactor` | "refactor", "clean" | "Refactor {scope}. Preserve behavior. Show: what, why, before/after." | | `generic` | fallback | Use the user's exact wording as the objective. | --- ## STEP 2 โ€” GENERATE RUN ID AND DIRECTORIES ```python python3 -c ' import datetime, os run_id = f"run-{datetime.datetime.now().strftime("%Y%m%d-%H%M%S")}" repo_path = "THE_REPO_PATH" base = os.path.join(repo_path, ".stampede", run_id) for d in ["queue", "claimed", "results", "logs", "pids"]: os.makedirs(f"{base}/{d}", exist_ok=True) print(f"RUN_ID={run_id}") print(f"BASE={base}") ' ``` Ensure `.stampede/` is in `.gitignore`: ```bash cd REPO_PATH grep -q '.stampede' .gitignore 2>/dev/null || echo '.stampede/' >> .gitignore ``` All coordination uses these directories โ€” zero infrastructure, pure filesystem IPC: - `queue/` โ€” tasks waiting to be claimed - `claimed/` โ€” tasks being worked on - `results/` โ€” completed task outputs - `logs/` โ€” per-worker JSONL logs + orchestrator log - `pids/` โ€” worker PID files for liveness checks --- ## STEP 3 โ€” GATHER REPO CONTEXT Collect context ONCE. Embed in every manifest so agents start warm. ```bash cd REPO_PATH # README excerpt README_EXCERPT=$(head -200 README.md 2>/dev/null || echo "No README found") # Directory tree (pruned) TREE=$(find . -maxdepth 3 \ -not -path '*node_modules*' -not -path '*venv*' \ -not -path '*.git/*' -not -path '*__pycache__*' -not -path '*dist*' \ | sed 's#^\./##' | head -150) # Detect test command if [ -f package.json ]; then TEST_CMD=$(python3 -c "import json; d=json.load(open('package.json')); print(d.get('scripts',{}).get('test','npm test'))") elif [ -f pyproject.toml ] || [ -d tests ]; then TEST_CMD="pytest -q" elif [ -f go.mod ]; then TEST_CMD="go test ./..." elif [ -f Makefile ] && grep -q '^test:' Makefile; then TEST_CMD="make test" else TEST_CMD="" fi ``` --- ## STEP 4 โ€” SPLIT WORK INTO TASK MANIFESTS Create non-overlapping task manifests. Each task gets exclusive file ownership. Use python3 for ALL JSON operations. ```python python3 -c ' import json, os run_id = "THE_RUN_ID" base = "THE_BASE_DIR" objective = """THE_OBJECTIVE""" repo_path = "THE_REPO_PATH" repo_context = { "readme_excerpt": """THE_README"""[:8000], "tree": """THE_TREE"""[:12000], "test_command": "THE_TEST_CMD" } scope_files = [] # populated from glob/grep analysis of repo worker_count = WORKER_COUNT chunk_size = max(1, len(scope_files) // worker_count) chunks = [scope_files[i:i+chunk_size] for i in range(0, len(scope_files), chunk_size)] for idx, chunk in enumerate(chunks): task_id = f"task-{idx+1:03d}" manifest = { "task_id": task_id, "run_id": run_id, "title": f"Process group {idx+1}", "objective": objective, "generation": 0, "files": chunk, "repo_path": repo_path, "branch": f"stampede/{task_id}", "repo_context": repo_context, "constraints": { "max_result_words": 500, "branch_prefix": "stampede", "no_main_commits": True }, "context": { "total_tasks": len(chunks), "task_index": idx, "related_tasks": [f"task-{j+1:03d}" for j in range(len(chunks)) if j != idx] } } path = os.path.join(base, "queue", f"{task_id}.json") with open(path, "w") as f: json.dump(manifest, f, indent=2) print(f"Created {path}") ' ``` Insert the run and each task into SQL: ```sql INSERT INTO stampede_runs (run_id, objective, repo_path, model, worker_count, total_tasks) VALUES ('RUN_ID', 'OBJECTIVE', 'REPO', 'MODEL', N, T); INSERT INTO stampede_tasks (task_id, run_id, title, objective, branch) VALUES ('task-001', 'RUN_ID', 'title', 'objective', 'stampede/task-001'); -- repeat for each task ``` --- ## STEP 5 โ€” PERSIST STATE FOR CRASH RECOVERY Write `state.json` after every state-changing step. ```python python3 -c ' import json, os, glob as g, time base = "THE_BASE_DIR" state = { "run_id": "THE_RUN_ID", "base": base, "objective": "THE_OBJECTIVE", "repo_path": "THE_REPO_PATH", "model": "THE_MODEL", "worker_count": WORKER_COUNT, "total_tasks": TOTAL_TASKS, "phase": "stampedeing", "tasks": { "queued": [os.path.basename(f).replace(".json","") for f in sorted(g.glob(f"{base}/queue/*.json"))], "claimed": [os.path.basename(f).replace(".json","") for f in sorted(g.glob(f"{base}/claimed/*.json"))], "completed": [os.path.basename(f).replace(".json","") for f in sorted(g.glob(f"{base}/results/*.json"))] }, "workers": [], "updated_at": time.strftime("%Y-%m-%dT%H:%M:%SZ", time.gmtime()) } with open(f"{base}/state.json", "w") as f: json.dump(state, f, indent=2) ' ``` ### state.json Shape ```json { "run_id": "run-20250715-143022", "base": "REPO_PATH/.stampede/run-20250715-143022", "objective": "...", "repo_path": "/abs/path", "model": "claude-sonnet-4.5", "phase": "stampedeing|running|synthesizing|completed", "tasks": { "queued": [], "claimed": [], "completed": [] }, "workers": [{ "worker_id": "a1b2c3", "pid": 12345, "status": "alive" }], "updated_at": "ISO-8601" } ``` --- ## STEP 5.5 โ€” SEALED-ENVELOPE TEST GENERATION (Shadow Score) Before launching agents, generate sealed tests from the task specifications using the [Shadow Score protocol](https://github.com/DUBSOpenHub/shadow-score-spec). These tests are hidden from agents and run after merge to measure blind spots. **Principle:** The agents never see these tests. They write their own tests for their own code. The sealed tests measure: "Did the agent actually satisfy the requirement, or just write code that passes its own tests?" ### Generate sealed tests For each task manifest, use a separate `task` agent call (context-isolated from the worker agents) to generate specification-based tests: ```python python3 -c ' import json, os base = "THE_BASE_DIR" sealed_dir = os.path.join(base, "sealed-tests") os.makedirs(sealed_dir, exist_ok=True) # Read each task manifest queue_dir = os.path.join(base, "queue") for qf in sorted(os.listdir(queue_dir)): if not qf.endswith(".json"): continue with open(os.path.join(queue_dir, qf)) as f: task = json.load(f) print(f"SEAL: {task[\"task_id\"]} โ€” {task.get(\"title\", task.get(\"objective\", \"\")[:60])}") ' ``` For each task, dispatch a `task` agent (explore type) with this prompt: > You are a Seal Author for the Shadow Score protocol. Given this task specification, > generate 3-5 acceptance tests that verify the REQUIREMENTS, not implementation details. > > Task: {task_title} > Objective: {task_objective} > Scope files: {task_files} > > Write tests as a shell script that exits 0 on pass, non-zero on fail. > Each test should check ONE requirement. Output the test script only. Save each sealed test to `{base}/sealed-tests/{task_id}.sh`. Make them executable. ### Hash the sealed envelope After generating all sealed tests, compute a tamper-evidence hash: ```bash find THE_BASE_DIR/sealed-tests -name "*.sh" -exec sha256sum {} \; | sort | sha256sum > THE_BASE_DIR/sealed-tests/.seal-hash ``` Store the hash in state.json so it can be verified later โ€” proving tests weren't modified after agents started working. **Important:** Do NOT share sealed test contents with agents. The worker agent prompt must never reference `sealed-tests/`. Only share failure messages (not test source) during hardening. --- ## STEP 6 โ€” LAUNCH AGENTS Invoke the launcher with `bash(mode="async", detach=true)` and `--no-attach` (the skill handles window opening): ```bash chmod +x ~/bin/stampede.sh ~/bin/stampede.sh \ --run-id THE_RUN_ID \ --count WORKER_COUNT \ --repo THE_REPO_PATH \ --model THE_MODEL \ --no-attach ``` Wait 5 seconds, then verify the tmux session exists: ```bash tmux has-session -t "stampede-THE_RUN_ID" 2>/dev/null && echo "FLEET_RUNNING" || echo "FLEET_FAILED" ``` **IMMEDIATELY after confirming FLEET_RUNNING**, open a Terminal window so the user can watch. Run this with `bash` (NOT detached โ€” needs GUI access): ```bash ATTACH_SCRIPT=$(mktemp /tmp/stampede-attach-XXXXXX.sh) cat > "$ATTACH_SCRIPT" << 'EOF' #!/usr/bin/env bash clear echo "๐Ÿฆฌ Connecting to Terminal Stampede..." sleep 0.5 tmux attach -t stampede-THE_RUN_ID EOF chmod +x "$ATTACH_SCRIPT" open -a Terminal "$ATTACH_SCRIPT" ``` Tell the user: "๐Ÿฆฌ **Stampede is running!** A Terminal window just opened showing your agents working in real time. Come back here when they're done for the full report." Update state.json phase to `"running"`. Log the event: ```bash echo '{"ts":"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'","event":"fleet_launched","run_id":"RUN_ID","workers":N}' >> "BASE/logs/orchestrator.jsonl" ``` --- ## STEP 7 โ€” POLL, MONITOR, AND RECOVER Core monitoring loop. Poll every 20 seconds until all tasks are terminal. ```python python3 -c ' import os, json, time base = "THE_BASE_DIR" total = TOTAL_TASKS max_generation = 2 while True: queued = [f for f in os.listdir(os.path.join(base, "queue")) if f.endswith(".json")] claimed = [f for f in os.listdir(os.path.join(base, "claimed")) if f.endswith(".json")] results = [f for f in os.listdir(os.path.join(base, "results")) if f.endswith(".json")] done = len(results) # Progress bar pct = int(done / total * 100) if total > 0 else 0 filled = pct // 5 bar = "โ–ˆ" * filled + "โ–‘" * (20 - filled) # PID heartbeat โ€” Landmine #4, #16 live, dead_workers = 0, [] pids_dir = os.path.join(base, "pids") if os.path.isdir(pids_dir): for pf in os.listdir(pids_dir): if not pf.endswith(".pid"): continue wid = pf.replace(".pid", "") try: with open(os.path.join(pids_dir, pf)) as f: pid = int(f.read().strip()) os.kill(pid, 0) # signal 0 = alive check live += 1 except (ProcessLookupError, ValueError, PermissionError, FileNotFoundError): dead_workers.append((wid, os.path.join(pids_dir, pf))) print(f"[{bar}] {pct}% ({done}/{total}) | q={len(queued)} c={len(claimed)} | alive={live} dead={len(dead_workers)}") if done >= total: print("All tasks complete.") break if len(queued) == 0 and len(claimed) == 0 and done < total: print("No pending tasks but incomplete.") break # Dead worker recovery โ€” Landmine #5 for wid, pid_path in dead_workers: for cf in list(claimed): claimed_path = os.path.join(base, "claimed", cf) try: with open(claimed_path) as f: task = json.load(f) if task.get("claimed_by") != wid: continue gen = task.get("generation", 0) + 1 if gen > max_generation: task["status"] = "failed" task["error"] = "max_generation_exceeded" with open(os.path.join(base, "results", cf), "w") as f: json.dump(task, f, indent=2) os.remove(claimed_path) else: task["generation"] = gen task.pop("claimed_by", None) task.pop("claimed_at", None) with open(os.path.join(base, "queue", cf), "w") as f: json.dump(task, f, indent=2) os.remove(claimed_path) except (json.JSONDecodeError, FileNotFoundError): pass try: os.remove(pid_path) # Landmine #9 except FileNotFoundError: pass # Orphan sweep: stale claims >10min โ€” Landmine #19 now = time.time() for cf in list(os.listdir(os.path.join(base, "claimed"))): if not cf.endswith(".json"): continue claimed_path = os.path.join(base, "claimed", cf) try: if now - os.path.getmtime(claimed_path) > 600: with open(claimed_path) as f: task = json.load(f) gen = task.get("generation", 0) + 1 if gen <= max_generation: task["generation"] = gen task.pop("claimed_by", None) task.pop("claimed_at", None) with open(os.path.join(base, "queue", cf), "w") as f: json.dump(task, f, indent=2) os.remove(claimed_path) except (json.JSONDecodeError, FileNotFoundError): pass time.sleep(20) ' ``` After loop, update SQL: ```sql UPDATE stampede_runs SET completed_tasks = (SELECT COUNT(*) FROM stampede_tasks WHERE run_id = 'RUN_ID' AND status = 'done'), failed_tasks = (SELECT COUNT(*) FROM stampede_tasks WHERE run_id = 'RUN_ID' AND status = 'failed'), updated_at = datetime('now') WHERE run_id = 'RUN_ID'; ``` Persist state with phase = `"synthesizing"`. --- ## STEP 8 โ€” SYNTHESIZE RESULTS WITH CONFLICT DETECTION ```python python3 -c ' import json, os from collections import defaultdict base = "THE_BASE_DIR" results_dir = os.path.join(base, "results") all_results = [] file_owners = defaultdict(list) for rf in sorted(os.listdir(results_dir)): if not rf.endswith(".json"): continue with open(os.path.join(results_dir, rf)) as f: result = json.load(f) # Landmine #15: verify run_id if result.get("run_id") and result["run_id"] != "THE_RUN_ID": continue all_results.append(result) for fp in result.get("files_changed", result.get("files_modified", [])): file_owners[fp].append(result.get("task_id", rf)) # Conflict detection โ€” Landmine #6, #7 conflicts = {fp: tasks for fp, tasks in file_owners.items() if len(tasks) > 1} if conflicts: print("โš ๏ธ CONFLICTS DETECTED:") for fp, tasks in conflicts.items(): print(f" {fp} โ† modified by {tasks}") branches = [r.get("branch") for r in all_results if r.get("branch")] if branches: print(f"๐Ÿ“Œ {len(branches)} branches: {branches}") # Deterministic output sorted by task_id print("=" * 60) print("STAMPEDE RESULTS SYNTHESIS") print("=" * 60) succeeded = failed = 0 for r in sorted(all_results, key=lambda x: x.get("task_id", "")): tid = r.get("task_id", "unknown") status = r.get("status", "unknown") summary = r.get("summary", "No summary") error = r.get("error", "") if status in ("done", "completed"): succeeded += 1;

For non-conflicting branches, suggest merge: ```bash cd REPO_PATH git checkout main 2>/dev/null || git checkout master for branch in $(git branch --list 'stampede/*' | tr -d ' '); do git merge --no-ff "$branch" -m "Merge $branch" || { echo "Conflict on $branch"; git merge --abort; } done ``` --- ## STEP 8.5 โ€” AUTO-MERGE WITH SHADOW SCORING After synthesis, offer the auto-merger. This merges all agent branches into a single combined branch and shadow-scores each agent's work quality across 3 layers. ### Offer merge Use `ask_user` with the question: > "๐Ÿฆฌ Auto-merge all agent branches into one? The merger will resolve conflicts using AI and shadow-score each agent's work quality." Choices: **Auto-merge + score (Recommended)**, **Manual (I'll merge myself)**, **Skip** ### If accepted: Launch the merger ```bash chmod +x ~/bin/stampede-merge.sh ~/bin/stampede-merge.sh \ --run-id THE_RUN_ID \ --repo THE_REPO_PATH \ --model THE_MODEL ``` Wait for the merger to complete, then read the merge report: ```python python3 -c ' import json, os report_path = "THE_BASE_DIR/merge-report.json" if not os.path.exists(report_path): print("NO_REPORT") exit(0) with open(report_path) as f: report = json.load(f) s = report.get("summary", {}) print(f"MERGED: {s.get(\"clean_merges\",0)} clean, {s.get(\"conflicts_resolved\",0)} resolved, {s.get(\"skipped\",0)} skipped") print(f"BRANCH: {report.get(\"merged_branch\",\"?\")}") print(f"AVG_SCORE: {s.get(\"avg_score\",\"?\")}") ' ``` ### Show the shadow scorecard Present scores in a formatted table.
