Queen / Colony Debug Skill

SkillAI & models

This skill lets your AI find and fix problems in its own multi-agent sessions and worker pipelines. All debugging runs in an isolated test runtime. It is built for multi-agent AI setups used in production.

Available today. Use it from your connected AI after setup.

After adding the skill, ask your AI to debug a multi-agent session or worker pipeline whenever something is not working as expected.

Then ask your AI: use the Queen / Colony Debug Skill skill

What your AI can do with it

  • Find and fix problems in its own multi-agent sessions
  • Debug its worker pipeline
  • Run debugging in an isolated test runtime
  • Support multi-agent AI setups in production

What this skill tells your AI

The instructions your AI receives, as published by aden-hive/hive in .claude/skills/queen-colony-debug/SKILL.md and read by ahel’s review.

SOP for live debugging of queen sessions, colony forks, worker spawns, and tracker DB plumbing without touching the user's production Hive Desktop. Use this when something is wrong in the create_colony → tracker → run_parallel_workers → worker pipeline.

Trigger

User asks you to debug, reproduce, or verify behavior in:

  • Queen DM sessions, colony sessions, fork_session_into_colony
  • ColonyBinding propagation (queen exec context, worker input_data)
  • tracker_sql / tracker_register_writable / tracker_upsert / tracker_query
  • run_parallel_workers preflight
  • Phantom colonies/session_<uuid>/ shadow folders (the original split-brain bug)
  • Session resume from disk, queen phase transitions (independent → incubating → colony)

Examples: "queen says no such table", "workers can't see what queen wrote", "phantom colony folder appeared", "verify my colony refactor didn't break anything".

Hard rules

  1. Never run against the user's real Hive Desktop runtime by default. Use an isolated HIVE_HOME=/tmp/hive_e2e first. Only switch to the real HIVE_HOME (~/Library/Application Support/Hive/users/<hash>) when the user has explicitly asked for live LLM verification or when an offline repro is impossible.
  2. Never read the real secrets/, credentials/, or configuration.json directories. The auto-mode classifier will block credential exploration. You don't need their contents — the server reads them itself.
  3. Pick a non-default port (--port 8901/8902/8903) so you don't collide with a running Hive Desktop on 8787.
  4. Background the server, don't foreground it. & redirects the log to a file you can tail/grep while you make HTTP calls in parallel.
  5. For "wait for thing X" patterns: use Bash run_in_background:true with an until grep -q ... loop — never chain sleep N. The harness blocks long leading sleeps.
  6. LLM-driven turns cost real credits. Budget your queen prompts: prefer terse, deterministic instructions ("just call create_colony with these exact args") over open-ended questions.

What "correct" looks like (key invariants)

These are the invariants the refactor enforces; verifying them is most of the job:

  • A DM queen session must not create colonies/<session_uuid>/ (the phantom-folder bug). Only on-disk colony names live under colonies/.
  • worker.json input_data carries exactly one key: {"binding": {"name", "dir", "tracker_db"}}. No tracker_db_path, no colony_id (those are legacy and get stripped by _patch_worker_configs on every server boot).
  • The queen and her workers in a given colony share one tracker.db — the one inside colonies/<name>/data/.
  • Tools refuse with "no colony context — this tool only works inside a colony" when called without a binding. They never synthesize paths.
  • run_parallel_workers emits the log line run_parallel_workers: attached binding to N spawn(s) (colony=<name>). If that line is missing, the binding plumbing is broken.

Authoritative source for the binding model: core/framework/host/colony_binding.py.

SOP

Step 1 — Pick a runtime

Default to isolated:

mkdir -p /tmp/hive_e2e/colonies /tmp/hive_e2e/agents/queens
PORT=8901
HIVE_HOME=/tmp/hive_e2e uv run hive serve --port $PORT --verbose 2>&1 > /tmp/hive_e2e/server.log &
echo "pid: $!"

Confirm it's up:

until curl -sf http://127.0.0.1:$PORT/api/health >/dev/null 2>&1; do sleep 1; done
curl -s http://127.0.0.1:$PORT/api/health

For real-runtime verification (only when explicitly requested):

REAL="/Users/aden/Library/Application Support/Hive/users/<the-user-hash>"  # find via: ls ~/Library/Application\ Support/Hive/users/
HIVE_HOME="$REAL" uv run hive serve --port 8903 --verbose 2>&1 > /tmp/hive_real.log &

Verify Commercial extensions loaded appears in the startup log; that's the green light.

Step 2 — Snapshot the starting state

echo "=== colonies dir ==="; ls "$HIVE_HOME/colonies/"
echo "=== queens ==="; ls "$HIVE_HOME/agents/queens/" 2>&1 | head -10
echo "=== existing sessions ==="; curl -s http://127.0.0.1:$PORT/api/sessions | uv run python -m json.tool

Anything session_* under colonies/ BEFORE you do anything is an existing phantom-folder issue.

Step 3 — Drive the failing flow

(a) Create a DM session (queen-only, no LLM-side actions)
RESP=$(curl -s -X POST http://127.0.0.1:$PORT/api/sessions -H 'Content-Type: application/json' \
  -d '{"queen_name": "queen_technology"}')
SESSION_ID=$(echo "$RESP" | uv run python -c "import json,sys; print(json.load(sys.stdin)['session_id'])")
echo "$SESSION_ID"

Invariant check: colonies/ should still be empty. If colonies/session_$SESSION_ID/ appeared, the phantom-folder bug is back. Suspect: ColonyRuntime.__init__ re-introduced an unconditional ensure_task_list(colony:<colony_id>) call.

(b) Fork DM into a colony — non-LLM path

This drives fork_session_into_colony without burning credits on a queen turn:

curl -s -X POST "http://127.0.0.1:$PORT/api/sessions/$SESSION_ID/colony-spawn" \
  -H 'Content-Type: application/json' \
  -d '{"colony_name":"debug_test","task":"debug"}' | uv run python -m json.tool

Expected response shape: {colony_path, colony_name, queen_session_id, is_new, compaction_status}. No tracker_db_path field — if it's there, the cleanup regressed.

Then verify the on-disk binding:

uv run python -c "
import json
cfg = json.load(open('$HIVE_HOME/colonies/debug_test/worker.json'))
print(json.dumps(cfg.get('input_data'), indent=2))
"

Expected:

{
  "binding": {
    "name": "debug_test",
    "dir": "/.../colonies/debug_test",
    "tracker_db": "/.../colonies/debug_test/data/tracker.db"
  }
}

If you see tracker_db_path or colony_id keys here, worker_definition.build_input_data or routes_execution.fork_session_into_colony is writing the legacy shape.

(c) LLM-driven path (talk to the queen)

Only use when (b) isn't enough. Send a tight, deterministic prompt:

curl -s -X POST "http://127.0.0.1:$PORT/api/sessions/$SESSION_ID/chat" \
  -H 'Content-Type: application/json' \
  -d '{"message": "Just call create_colony(colony_name=\"debug_e2e\", task=\"debug\"). Do nothing else."}'

Then watch for the actual tool call (this is the right way to wait — no sleep chains):

# In Bash with run_in_background:true
until grep -qE "tool_call: create_colony|Forked queen to colony|colony fork failed" /tmp/hive_e2e/server.log; do sleep 5; done

When background command exits, grep the log for what actually happened:

grep -E "tool_call: create_colony|Forked queen to colony|colony fork failed|fork_session" /tmp/hive_e2e/server.log | tail -10
(d) Activate the colony's queen session (post-fork, for tracker work)

fork_session_into_colony creates a separate colony-queen session on disk (returned as queen_session_id) that isn't loaded into the SessionManager until you ask. To talk to it:

COLONY_SESSION="<queen_session_id from fork response>"
COLONY_PATH="$HIVE_HOME/colonies/debug_e2e"
curl -s -X POST http://127.0.0.1:$PORT/api/sessions \
  -H 'Content-Type: application/json' \
  -d "{\"agent_path\":\"$COLONY_PATH\", \"queen_resume_from\":\"$COLONY_SESSION\", \"queen_name\":\"queen_technology\"}" \
  | uv run python -m json.tool

Verify queen_phase: "colony" in the response — that's when tracker tools are exposed. If she's still "independent", she lost her binding on resume; check queen_orchestrator.py:_queen_loop — it should call ColonyBinding.for_name(session.colony_name) and stamp the exec context.

(e) Drive the queen→worker tracker flow
curl -s -X POST "http://127.0.0.1:$PORT/api/sessions/$COLONY_SESSION/chat" \
  -H 'Content-Type: application/json' \
  -d '{"message": "Run tracker_sql to CREATE TABLE x (id INTEGER PRIMARY KEY, body TEXT). Then CREATE UNIQUE INDEX x_id ON x(id). Then tracker_register_writable(table=x, write_columns=[body], key_columns=[id]). Then INSERT INTO x VALUES (1, \"seed\"). Then run_parallel_workers with one task that calls tracker_upsert to set body=\"worker wrote\" on id=1, then report_to_parent."}'

(Note: INTEGER PRIMARY KEY does NOT register as a unique index in SQLite's PRAGMA index_list — you need an explicit CREATE UNIQUE INDEX. This is pre-existing validator behavior in tracker_tools, not a refactor regression.)

Then wait for the marker line:

# Bash run_in_background:true
until grep -q "attached binding to" /tmp/hive_e2e/server.log; do sleep 3; done
grep "attached binding to" /tmp/hive_e2e/server.log

Expected line: run_parallel_workers: attached binding to N spawn(s) (colony=debug_e2e). Missing → binding plumbing broken in queen_lifecycle_tools.py::run_parallel_workers.

Step 4 — Verify with sqlite3 directly

Cut out the HTTP layer and look at the raw tracker DB:

sqlite3 "$HIVE_HOME/colonies/debug_e2e/data/tracker.db" ".schema"
sqlite3 "$HIVE_HOME/colonies/debug_e2e/data/tracker.db" "SELECT * FROM _tracker_registry"
sqlite3 "$HIVE_HOME/colonies/debug_e2e/data/tracker.db" "SELECT * FROM x"  # or whatever table

Confirm there is no second DB at a session-id-named path:

ls "$HIVE_HOME/colonies/" | grep "^session_" && echo "PHANTOM FOLDER PRESENT (BUG)" || echo "clean ✓"
find "$HIVE_HOME/colonies" -name "tracker.db" -type f

There should be exactly one tracker.db per real colony. Multiple means split-brain.

Step 5 — Test refusal behavior without an LLM

Cheap Python repro of "tools refuse without binding":

HIVE_HOME=/tmp/hive_e2e uv run python -c "
import asyncio
from framework.tools.tracker_tools import _make_tracker_sql_executor, _make_tracker_query_executor, _make_tracker_upsert_executor, _make_tracker_register_executor

async def main():
    for name, mk in [
        ('tracker_sql', _make_tracker_sql_executor),
        ('tracker_query', _make_tracker_query_executor),
        ('tracker_upsert', _make_tracker_upsert_executor),
        ('tracker_register', _make_tracker_register_executor),
    ]:
        r = await mk()({'sql': 'SELECT 1', 'table': 'x', 'row': {'a': 1}, 'write_columns': ['a'], 'key_columns': ['a']})
        ok = r.get('success') is False and 'no colony context' in r.get('error', '')
        print(f'  {name}: {\"REFUSED ✓\" if ok else \"UNEXPECTED ✗\"} → {r}')

asyncio.run(main())
"

Step 6 — Test queen↔worker tracker sharing (offline)

Exercises the entire binding flow in-process, no LLM cost:

HIVE_HOME=/tmp/hive_e2e uv run python -c "
import asyncio
from framework.host.colony_binding import ColonyBinding
from framework.host.tracker_db import ensure_tracker_db
from framework.loader.tool_registry import ToolRegistry
from framework.tools.tracker_tools import (
    _make_tracker_sql_executor,
    _make_tracker_register_executor,
    _make_tracker_upsert_executor,
    _make_tracker_query_executor,
)

async def main():
    binding = ColonyBinding.for_name('offline_test')
    ensure_tracker_db(binding.dir)

    # Queen: DDL + register + seed
    tok = ToolRegistry.set_execution_context(binding=binding)
    try:
        sql = _make_tracker_sql_executor()
        await sql({'sql': 'CREATE TABLE t (k TEXT PRIMARY KEY, v TEXT)'})
        await sql({'sql': 'CREATE UNIQUE INDEX t_k ON t(k)'})
        await _make_tracker_register_executor()({'table': 't', 'write_columns': ['v'], 'key_columns': ['k']})
        await sql({'sql': \"INSERT INTO t VALUES ('a', 'queen')\"})
    finally:
        ToolRegistry.reset_execution_context(tok)

    # Worker: read + upsert from a SEPARATE exec context (binding comes via input_data)
    binding_from_input = ColonyBinding.from_dict(binding.to_dict())
    tok = ToolRegistry.set_execution_context(binding=binding_from_input)
    try:
        r = await _make_tracker_query_executor()({'sql': 'SELECT * FROM t'})
        print('worker SELECT:', r.get('rows'))
        assert r.get('rows') == [['a', 'queen']], 'split-brain: worker saw a different DB!'

        await _make_tracker_upsert_executor()({'table': 't', 'row': {'k': 'a', 'v': 'worker'}})
    finally:
        ToolRegistry.reset_execution_context(tok)

    # Queen: confirm worker's write is visible
    tok = ToolRegistry.set_execution_context(binding=binding)
    try:
        r = await _make_tracker_sql_executor()({'sql': 'SELECT * FROM t'})
        assert r.get('rows') == [['a', 'worker']], 'split-brain: queen lost worker write!'
        print('queen SELECT:', r.get('rows'))
    finally:
        ToolRegistry.reset_execution_context(tok)
    print('✓ queen+worker share the same tracker.db')

asyncio.run(main())
"

If both asserts pass: binding plumbing intact. If either fails: the split-brain bug is back; check _resolve_tracker_db_path-equivalents weren't reintroduced in tracker_tools.py.

Step 7 — Shut down cleanly

pkill -f "hive serve --port $PORT"
sleep 2
ps aux | grep "hive serve" | grep -v grep || echo "(clean)"

If you used HIVE_HOME=/tmp/hive_e2e, optionally rm -rf /tmp/hive_e2e when done.

If you used the real HIVE_HOME: do not auto-clean. Tell the user which colonies you created (debug_test, debug_e2e, etc.) and which orphan queen sessions exist under agents/queens/<queen_id>/sessions/, and let them decide.

Common failure patterns

SymptomFirst place to look
colonies/session_<uuid>/ directory exists after a DM sessionColonyRuntime.__init__ — check the ensure_task_list call is guarded by if self._binding:
Worker gets sqlite error: no such table even though queen registered itTwo tracker.db files exist; queen and worker have different binding paths. grep "attached binding" log — colony name should match the on-disk dir.
Tools refuse with "no colony context" mid-sessionQueen lost her exec context. After fork_session_into_colony, ToolRegistry.set_execution_context(binding=...) must run in the queen's task (the tool path), or session.binding must be set so _queen_loop re-stamps on next iteration.
worker.json input_data has tracker_db_path instead of bindingEither build_input_data regressed, or _patch_worker_configs didn't run on startup. Logs show tracker_db: patched N worker config(s) ... with fresh binding if the migration fired.
run_parallel_workers returns "no colony binding in the execution context"The queen's tool runs inside the queen's asyncio task. If you got there via HTTP /colony-spawn instead of the queen calling create_colony herself, her contextvar wasn't updated. Drive it through the queen's chat instead.
Colony queen session opens in independent phase, missing tracker toolssession.colony_name was None when _queen_loop started. Check _load_worker_core / create_session path is setting both colony_name and binding.

Key file index

When investigating, these are the load-bearing files:

Anti-patterns

  • ❌ Long leading sleep N to wait for an LLM turn → use Bash run_in_background:true with until grep -q ...; do sleep N; done.
  • cat the real secrets//credentials//configuration.json → the classifier blocks it and you don't need it.
  • ❌ Open-ended prompts like "please test the colony stuff for me" → the queen will spend 5+ turns researching. Always say exactly which tool to call with which args.
  • ❌ Asserting success purely from the JSON response — always cross-check sqlite3 and ls colonies/ for invariants.
  • ❌ Running against the user's real Hive port (default 8787) if their desktop app is up → port-conflict crash. Use 8901+.
