Stampede — 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

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:

"🦬 What repo and tasks? Example: stampede 8 agents on ~/dev/my-app : add tests; fix errors; update docs"

STEP 0 — SQL SCHEMA (run on every invocation)

Always initialize SQL tables first. This ensures state survives crashes.

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 — PARSE THE REQUEST

Extract from the user's natural-language prompt:

If stampede resume [RUN_ID] → skip to STEP 9. If stampede status → query SQL + filesystem, report. If stampede teardown [RUN_ID] → run ~/bin/stampede.sh --teardown --run-id RUN_ID. If ambiguous → use ask_user to clarify scope and objective.

Objective Templates

Sharpen each task objective based on detected type.

STEP 2 — GENERATE RUN ID AND DIRECTORIES

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:

cd REPO_PATH
grep -q '.stampede' .gitignore 2>/dev/null || echo '.stampede/' >> .gitignore

All coordination uses these directories — zero infrastructure, pure filesystem IPC:

• queue/ — tasks waiting to be claimed
• claimed/ — tasks being worked on
• results/ — completed task outputs
• logs/ — per-worker JSONL logs + orchestrator log
• pids/ — worker PID files for liveness checks

STEP 3 — GATHER REPO CONTEXT

Collect context ONCE. Embed in every manifest so agents start warm.

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 — SPLIT WORK INTO TASK MANIFESTS

Create non-overlapping task manifests. Each task gets exclusive file ownership.

Use python3 for ALL JSON operations.

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:

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 — PERSIST STATE FOR CRASH RECOVERY

Write state.json after every state-changing step.

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

{
  "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 — SEALED-ENVELOPE TEST GENERATION (Shadow Score)

Before launching agents, generate sealed tests from the task specifications using the Shadow Score protocol. 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:

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\"]} — {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:

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 — 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 — LAUNCH AGENTS

Invoke the launcher with bash(mode="async", detach=true) and --no-attach (the skill handles window opening):

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:

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 — needs GUI access):

ATTACH_SCRIPT=$(mktemp /tmp/stampede-attach-XXXXXX.sh)
cat > "$ATTACH_SCRIPT" << 'EOF'
#!/usr/bin/env bash
clear
echo "🦬 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: "🦬 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:

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 — POLL, MONITOR, AND RECOVER

Core monitoring loop. Poll every 20 seconds until all tasks are terminal.

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 = "█" * filled + "░" * (20 - filled)

    # PID heartbeat — 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 — 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 — 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

                    os.remove(claimed_path)
        except (json.JSONDecodeError, FileNotFoundError):
            pass

    time.sleep(20)
'

After loop, update 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 — SYNTHESIZE RESULTS WITH CONFLICT DETECTION

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 — Landmine #6, #7
conflicts = {fp: tasks for fp, tasks in file_owners.items() if len(tasks) > 1}
if conflicts:
    print("⚠️  CONFLICTS DETECTED:")
    for fp, tasks in conflicts.items():
        print(f"  {fp} ← modified by {tasks}")

branches = [r.get("branch") for r in all_results if r.get("branch")]
if branches:
    print(f"📌 {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; icon = "✅"
    elif error or status in ("failed", "error"):
        failed += 1; icon = "❌"
    else:
        icon = "⚠️"
    print(f"\n{icon} {tid} [{status}]")
    print(f"   {summary[:500]}")
    if error:
        print(f"   Error: {error}")

print(f"\nTotal: {len(all_results)} | Succeeded: {succeeded} | Failed: {failed}")
if conflicts:
    print(f"Conflicts: {len(conflicts)} files need resolution")
print("=" * 60)
'

If conflicts, present to user via ask_user. For non-conflicting branches, suggest merge:

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 — 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:

"🦬 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

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:

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. Raw scores are 1-10 per dimension. The Total column uses weighted scoring (Completeness 30%, Scope 25%, Quality 20%, Test 15%, Conflict 10%) normalized to /50. Runtime bonuses shown separately.

Persist model stats (cross-run tracking)

After showing the scorecard, update the persistent model stats file:

python3 -c '
import json, os, time

stats_path = os.path.expanduser("~/.stampede/model-stats.json")
report_path = "THE_BASE_DIR/merge-report.json"

# Load existing stats or initialize
if os.path.exists(stats_path):
    with open(stats_path) as f:
        stats = json.load(f)
else:
    stats = {"models": {}, "runs": 0, "updated": None}

with open(report_path) as f:
    report = json.load(f)

stats["runs"] += 1

If 2+ runs exist, show a model leaderboard:

📊 Model Leaderboard (across N stampede runs)

 Rank  Model               Avg Score  Runs  Best  Worst
 ──────────────────────────────────────────────────────
  1.   claude-sonnet-4.5     43.2      12     48    37
  2.   gpt-5.1               40.1       8     45    33
  3.   claude-haiku-4.5      37.8       4     42    31

STEP 9 — CRASH RECOVERY (stampede resume)

python3 -c '
import json, os, glob as g

repo_path = "THE_REPO_PATH"
stampede_dir = os.path.join(repo_path, ".stampede")
run_id = "PROVIDED_OR_EMPTY"

if not run_id:
    runs = sorted(g.glob(f"{stampede_dir}/run-*/state.json"), reverse=True)
    if not runs:
        print("No stampede runs found.")
        exit(1)
    run_id = os.path.basename(os.path.dirname(runs[0]))

base = os.path.join(stampede_dir, run_id)
with open(os.path.join(base, "state.json")) as f:
    state = json.load(f)

# Re-queue all claimed tasks (workers dead after crash)
for cf in os.listdir(os.path.join(base, "claimed")):
    if not cf.endswith(".json"):
        continue
    src = os.path.join(base, "claimed", cf)
    with open(src) as f:
        task = json.load(f)
    gen = task.get("generation", 0) + 1
    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(src)
    print(f"Re-queued {cf} (generation {gen})")

remaining = len([f for f in os.listdir(os.path.join(base, "queue")) if f.endswith(".json")])
done = len([f for f in os.listdir(os.path.join(base, "results")) if f.endswith(".json")])
print(f"Resume: {done} done, {remaining} remaining")
'

Then proceed to STEP 6 (relaunch), then STEP 7 (poll).

STEP 10 — FINALIZE AND CLEANUP

Update state.json and SQL:

python3 -c '
import json, time
path = "THE_BASE_DIR/state.json"
with open(path) as f: state = json.load(f)
state["phase"] = "completed"
state["updated_at"] = time.strftime("%Y-%m-%dT%H:%M:%SZ", time.gmtime())
with open(path, "w") as f: json.dump(state, f, indent=2)
'

UPDATE stampede_runs
SET status = CASE WHEN failed_tasks = 0 THEN 'completed' ELSE 'failed' END,
    updated_at = datetime('now')
WHERE run_id = 'RUN_ID';

Offer: stampede teardown RUN_ID, stampede resume RUN_ID, branch links.

LANDMINE REFERENCE

IMPLEMENTATION CHECKLIST

• SQL tables exist (STEP 0)
• Run directory with all 5 subdirectories
• Task manifests are valid JSON in queue/
• ~/bin/stampede.sh is executable
• ~/.stampede/agents/stampede-agent.agent.md is installed (or equivalent for your CLI agent)
• tmux is available
• Target repo has .git directory
• --max-autopilot-continues 30 on agents
• Worker model configured (default: claude-sonnet-4.5)

COMPLETION CRITERIA

• queue/ empty
• claimed/ empty
• Every task has terminal result (done or failed)
• state.json phase is completed
• Synthesis includes conflict report (or explicit "none")
