Orchestrate — Agent Fleet Supervisor

One tmux session, N windows — each window is one agent working in its own worktree. Speak naturally; Claude maps your intent to the right scripts.

Scripts

SKILLS_DIR=$(git rev-parse --show-toplevel)/.claude/skills/orchestrate/scripts
STATE_FILE=~/.claude/orchestrator-state.json

Script	Purpose
find-spare.sh [REPO_ROOT]	List free worktrees — one PATH BRANCH per line

Supervision model

Orchestrating Claude (this Claude session — IS the supervisor)
  └── Reads pane output, checks CI, intervenes with targeted guidance
        run-loop.sh (separate tmux window, every 30s)
          └── Mechanical only: idle restart, dialog approval, recycle on ORCHESTRATOR:DONE

You (the orchestrating Claude) are the supervisor. After spawning agents, stay in this conversation and actively monitor: poll each agent's pane every 2-3 minutes, check CI, nudge stalled agents, and verify completions. Do not spawn a separate supervisor Claude window — it loses context, is hard to observe, and compounds context compression problems.

run-loop.sh is the mechanical layer — zero tokens, handles things that need no judgment: restart crashed agents, press Enter on dialogs, recycle completed worktrees (only after verify-complete.sh passes).

Checkpoint protocol

Agents output checkpoints as they complete each required step:

CHECKPOINT:<step-name>

Required steps are passed as args to spawn-agent.sh (e.g. pr-address pr-test). run-loop.sh will not recycle a window until all required checkpoints are found in the pane output. If verify-complete.sh fails, the agent is re-briefed automatically.

Worktree lifecycle

spare/N branch  →  spawn-agent.sh (--session-id UUID)  →  window + feat/branch + claude running
                                                                 ↓
                                               CHECKPOINT:<step> (as steps complete)
                                                                 ↓
                                                        ORCHESTRATOR:DONE
                                                                 ↓
                                    verify-complete.sh: checkpoints ✓ + 0 threads + CI green + no fresh CHANGES_REQUESTED
                                                                 ↓
                                              state → "done", notify, window KEPT OPEN
                                                                 ↓
                              user/orchestrator explicitly requests recycle
                                                                 ↓
                                         recycle-agent.sh → spare/N (free again)

Windows are never auto-killed. The worktree stays on its branch, the session stays alive. The agent is done working but the window, git state, and Claude session are all preserved until you choose to recycle.

To resume a done or crashed session:

# Resume by stored session ID (preferred — exact session, full context)
claude --resume SESSION_ID --permission-mode bypassPermissions

# Or resume most recent session in that worktree directory
cd /path/to/worktree && claude --continue --permission-mode bypassPermissions

To manually recycle when ready:

bash ~/.claude/orchestrator/scripts/recycle-agent.sh SESSION:WIN WORKTREE_PATH spare/N
# Then update state:
jq --arg w "SESSION:WIN" '.agents |= map(if .window == $w then .state = "recycled" else . end)' \
  ~/.claude/orchestrator-state.json > /tmp/orch.tmp && mv /tmp/orch.tmp ~/.claude/orchestrator-state.json

State file (~/.claude/orchestrator-state.json)

Never committed to git. You maintain this file directly using jq + atomic writes (.tmp → mv).

• last_rebriefed_at — Unix timestamp of last re-brief; enforces 5-min cooldown to prevent spam.

Agent states: running | idle | stuck | waiting_approval | complete | done | escalated

done means verified complete — window is still open, session still alive, worktree still on task branch. Not recycled yet.

Serial /pr-test rule

/pr-test and /pr-test --fix run local Docker + integration tests that use shared ports, a shared database, and shared build caches. Running two /pr-test jobs simultaneously will cause port conflicts and database corruption.

Rule: only one /pr-test runs at a time. The orchestrator serializes them.

You (the orchestrating Claude) own the test queue:

1. Agents do pr-review and pr-address in parallel — that's safe (they only push code and reply to GitHub).
2. When a PR needs local testing, add it to your mental queue — don't give agents a pr-test step.
3. Run /pr-test https://github.com/OWNER/REPO/pull/PR_NUMBER --fix yourself, sequentially.
4. Feed results back to the relevant agent via tmux send-keys:

   tmux send-keys -t SESSION:WIN "Local tests for PR #N: <paste failure output or 'all passed'>. Fix any failures and push, then output ORCHESTRATOR:DONE."
   sleep 0.3
   tmux send-keys -t SESSION:WIN Enter
   

5. Wait for CI to confirm green before marking the agent done.

If multiple PRs need testing at the same time, pick the one furthest along (fewest pending CI checks) and test it first. Only start the next test after the previous one completes.

Session restore (tested and confirmed)

Agent sessions are saved to disk. To restore a closed or crashed session:

# If session_id is in state (preferred):
NEW_WIN=$(tmux new-window -t SESSION -n WORKTREE_NAME -P -F '#{window_index}')
tmux send-keys -t "SESSION:${NEW_WIN}" "cd /path/to/worktree && claude --resume SESSION_ID --permission-mode bypassPermissions" Enter

# If no session_id (use --continue for most recent session in that directory):
tmux send-keys -t "SESSION:${NEW_WIN}" "cd /path/to/worktree && claude --continue --permission-mode bypassPermissions" Enter

--continue restores the full conversation history including all tool calls, file edits, and context. The agent resumes exactly where it left off. After restoring, update the window address in the state file:

jq --arg old "SESSION:OLD_WIN" --arg new "SESSION:NEW_WIN" \
  '(.agents[] | select(.window == $old)).window = $new' \
  ~/.claude/orchestrator-state.json > /tmp/orch.tmp && mv /tmp/orch.tmp ~/.claude/orchestrator-state.json

Intent → action mapping

Match the user's message to one of these intents:

The user says something like…	What to do
"status", "what's running", "show agents"	Run status.sh + capacity.sh, show output
"how many free", "capacity", "available worktrees"	Run capacity.sh, show output
"start N agents on X, Y, Z" or "run these tasks: …"	See Spawning agents below
"add task: …", "add one more agent for …"	See Adding an agent below
"stop", "shut down", "pause the fleet"	See Stopping below
"poll", "check now", "run a cycle"	Run poll-cycle.sh, process actions
"recycle window X", "free up autogpt3"	Run recycle-agent.sh directly

When the intent is ambiguous, show capacity first and ask what tasks to run.

Spawning agents

1. Resolve tmux session

tmux list-sessions -F "#{session_name}: #{session_windows} windows" 2>/dev/null

Use an existing session. Never create a tmux session from within Claude — it becomes a child of Claude's process and dies when the session ends. If no session exists, tell the user to run tmux new-session -d -s autogpt1 in their terminal first, then re-invoke /orchestrate.

2. Show available capacity

bash $SKILLS_DIR/capacity.sh $(git rev-parse --show-toplevel)

3. Collect tasks from the user

For each task, gather:

• objective — what to do (e.g. "implement feature X and open a PR")
• branch name — e.g. feat/my-feature (derive from objective if not given)
• pr_number — GitHub PR number if working on an existing PR (for verification)
• steps — required checkpoint names in order (e.g. pr-address pr-test) — derive from objective

Ask for idle_threshold_seconds only if the user mentions it (default: 300).

Never ask the user to specify a worktree — auto-assign from find-spare.sh.

4. Spawn one agent per task

# Get ordered list of spare worktrees
SPARE_LIST=$(bash $SKILLS_DIR/find-spare.sh $(git rev-parse --show-toplevel))

# For each task, take the next spare line:
WORKTREE_PATH=$(echo "$SPARE_LINE" | awk '{print $1}')
SPARE_BRANCH=$(echo "$SPARE_LINE" | awk '{print $2}')

# With PR number and required steps:
WINDOW=$(bash $SKILLS_DIR/spawn-agent.sh "$SESSION" "$WORKTREE_PATH" "$SPARE_BRANCH" "$NEW_BRANCH" "$OBJECTIVE" "$PR_NUMBER" "pr-address" "pr-test")

# Without PR (new work):
WINDOW=$(bash $SKILLS_DIR/spawn-agent.sh "$SESSION" "$WORKTREE_PATH" "$SPARE_BRANCH" "$NEW_BRANCH" "$OBJECTIVE")

Build an agent record and append it to the state file. If the state file doesn't exist yet, initialize it:

# Derive repo from git remote (used by verify-complete.sh + supervisor)
REPO=$(git remote get-url origin 2>/dev/null | sed 's|.*github\.com[:/]||; s|\.git$||' || echo "")

jq -n \
  --arg session "$SESSION" \
  --arg repo "$REPO" \
  --argjson threshold 300 \
  '{active:true, tmux_session:$session, idle_threshold_seconds:$threshold,
    repo:$repo, loop_window:null, supervisor_window:null, last_poll_at:0, agents:[]}' \
  > ~/.claude/orchestrator-state.json

Optionally add a Discord webhook for completion notifications:

jq --arg hook "$DISCORD_WEBHOOK_URL" '.discord_webhook = $hook' ~/.claude/orchestrator-state.json \
  > /tmp/orch.tmp && mv /tmp/orch.tmp ~/.claude/orchestrator-state.json

spawn-agent.sh writes the initial agent record (window, worktree_path, branch, objective, state, etc.) to the state file automatically — do not append the record again after calling it. The record already exists and pr_number/steps are patched in by the script itself.

5. Start the mechanical babysitter

LOOP_WIN=$(tmux new-window -t "$SESSION" -n "orchestrator" -P -F '#{window_index}')
LOOP_WINDOW="${SESSION}:${LOOP_WIN}"
tmux send-keys -t "$LOOP_WINDOW" "bash $SKILLS_DIR/run-loop.sh" Enter

jq --arg w "$LOOP_WINDOW" '.loop_window = $w' ~/.claude/orchestrator-state.json \
  > /tmp/orch.tmp && mv /tmp/orch.tmp ~/.claude/orchestrator-state.json

6. Begin supervising directly in this conversation

You are the supervisor. After spawning, immediately start your first poll loop (see Supervisor duties below) and continue every 2-3 minutes. Do NOT spawn a separate supervisor Claude window.

Adding an agent

Find the next spare worktree, then spawn and append to state — same as steps 2–4 above but for a single task. If no spare worktrees are available, tell the user.

Supervisor duties (YOUR job, every 2-3 min in this conversation)

You are the supervisor. Run this poll loop directly in your Claude session — not in a separate window.

Poll loop mechanism

You are reactive — you only act when a tool completes or the user sends a message. To create a self-sustaining poll loop without user involvement:

1. Start each poll with run_in_background: true + a sleep before the work:

   sleep 120 && tmux capture-pane -t autogpt1:0 -p -S -200 | tail -40
   # + similar for each active window
   

2. When the background job notifies you, read the pane output and take action.
3. Immediately schedule the next background poll — this keeps the loop alive.
4. Stop scheduling when all agents are done/escalated.

Never tell the user "I'll poll every 2-3 minutes" — that does nothing without a trigger. Start the background job instead.

Each poll: what to check

# 1. Read state
cat ~/.claude/orchestrator-state.json | jq '.agents[] | {window, worktree, branch, state, pr_number, checkpoints}'

# 2. For each running/stuck/idle agent, capture pane
tmux capture-pane -t SESSION:WIN -p -S -200 | tail -60

For each agent, decide:

What you see	Action
Spinner / tools running	Do nothing — agent is working
Idle ❯ prompt, no ORCHESTRATOR:DONE	Stalled — send specific nudge with objective from state
Stuck in error loop	Send targeted fix with exact error + solution
Waiting for input / question	Answer and unblock via tmux send-keys
CI red	gh pr checks PR_NUMBER --repo REPO → tell agent exactly what's failing
GitHub abuse rate limit error	Nudge: "Wait 60 seconds then continue posting replies with sleep 3 between each"
Context compacted / agent lost	Send recovery: `cat ~/.claude/orchestrator-state.json
ORCHESTRATOR:DONE in output	Query GraphQL for actual unresolved count. If >0, re-brief. If 0, run verify-complete.sh

Poll all windows from state, not from memory. Before each poll, run:

jq -r '.agents[] | select(.state | test("running|idle|stuck|waiting_approval|pending_evaluation")) | .window' ~/.claude/orchestrator-state.json

and capture every window listed. If you manually added a window outside spawn-agent.sh, ensure it's in the state file first.

RUNNING count includes waiting_approval agents

The RUNNING count from run-loop.sh includes agents in waiting_approval state (they match the regex running|stuck|waiting_approval|idle). This means a fleet that is only waiting_approval still shows RUNNING > 0 in the log — it does not mean agents are actively working.

When you see RUNNING > 0 in the run-loop log but suspect agents are actually blocked, check state directly:

jq '.agents[] | {window, state, worktree}' ~/.claude/orchestrator-state.json

A count of running=1 waiting=1 in the log actually means one agent is waiting for approval — the orchestrator should check and approve, not wait.

State file staleness recovery

The state file is written by scripts but can drift from reality when windows are closed, sessions expire, or the orchestrator restarts across conversations.

Signs of stale state:

• loop_window points to a window that no longer exists in the tmux session
• An agent's state is running but tmux window is closed or shows a shell prompt (not claude)
• last_seen_at is hours old but state still says running

Recovery steps:

1. Verify actual tmux windows:

tmux list-windows -t SESSION -F '#{window_index}: #{window_name} (#{pane_current_command})'

2. Cross-reference with state file:

jq -r '.agents[] | "\(.window) \(.state) \(.worktree)"' ~/.claude/orchestrator-state.json

3. Fix stale entries:

# Agent window closed — mark idle so run-loop.sh will restart it
jq --arg w "SESSION:WIN" '(.agents[] | select(.window==$w)).state = "idle"' \
  ~/.claude/orchestrator-state.json > /tmp/orch.tmp && mv /tmp/orch.tmp ~/.claude/orchestrator-state.json

# loop_window gone — kill the stale reference, then restart run-loop.sh
jq '.loop_window = null' ~/.claude/orchestrator-state.json > /tmp/orch.tmp && mv /tmp/orch.tmp ~/.claude/orchestrator-state.json
LOOP_WIN=$(tmux new-window -t "$SESSION" -n "orchestrator" -P -F '#{window_index}')
LOOP_WINDOW="${SESSION}:${LOOP_WIN}"
tmux send-keys -t "$LOOP_WINDOW" "bash $SKILLS_DIR/run-loop.sh" Enter
jq --arg w "$LOOP_WINDOW" '.loop_window = $w' ~/.claude/orchestrator-state.json \
  > /tmp/orch.tmp && mv /tmp/orch.tmp ~/.claude/orchestrator-state.json

4. After any state repair, re-run status.sh to confirm coherence before resuming supervision.

Strict ORCHESTRATOR:DONE gate

verify-complete.sh handles the main checks automatically (checkpoints, threads, CI green, spawned_at, and CHANGES_REQUESTED). Run it:

CHANGES_REQUESTED staleness rule: a CHANGES_REQUESTED review only blocks if it was submitted after the latest commit. If the latest commit postdates the review, the review is considered stale (feedback already addressed) and does not block. This avoids false negatives when a bot reviewer hasn't re-reviewed after the agent's fixing commits.

SKILLS_DIR=~/.claude/orchestrator/scripts
bash $SKILLS_DIR/verify-complete.sh SESSION:WIN

If it passes → run-loop.sh will recycle the window automatically. No manual action needed. If it fails → re-brief the agent with the failure reason. Never manually mark state done to bypass this.

Re-brief a stalled agent

Before sending any nudge, verify the pane is at an idle ❯ prompt. Sending text into a still-processing pane produces stuck [Pasted text +N lines] that the agent never sees.

Check:

tmux capture-pane -t SESSION:WIN -p 2>/dev/null | tail -5

If the last line shows a spinner (✳✽✢✶·), Running…, or no ❯ — wait 10–15s and check again before sending.

OBJ=$(jq -r --arg w SESSION:WIN '.agents[] | select(.window==$w) | .objective' ~/.claude/orchestrator-state.json)
PR=$(jq -r --arg w SESSION:WIN '.agents[] | select(.window==$w) | .pr_number' ~/.claude/orchestrator-state.json)
tmux send-keys -t SESSION:WIN "You appear stalled. Your objective: $OBJ. Check: gh pr view $PR --json title,body,headRefName to reorient."
sleep 0.3
tmux send-keys -t SESSION:WIN Enter

If image_path is set on the agent record, include: "Re-read context at IMAGE_PATH with the Read tool."

Self-recovery protocol (agents)

spawn-agent.sh automatically includes this instruction in every objective:

If your context compacts and you lose track of what to do, run: cat ~/.claude/orchestrator-state.json | jq '.agents[] | select(.window=="SESSION:WIN")' and gh pr view PR_NUMBER --json title,body,headRefName to reorient. Output each completed step as CHECKPOINT:<step-name> on its own line.

Passing images and screenshots to agents

tmux send-keys is text-only — you cannot paste a raw image into a pane. To give an agent visual context (screenshots, diagrams, mockups):

1. Save the image to a temp file with a stable path:

   # If the user drags in a screenshot or you receive a file path:
   IMAGE_PATH="/tmp/orchestrator-context-$(date +%s).png"
   cp "$USER_PROVIDED_PATH" "$IMAGE_PATH"
   

2. Reference the path in the objective string:

   OBJECTIVE="Implement the layout shown in /tmp/orchestrator-context-1234567890.png. Read that image first with the Read tool to understand the design."
   

3. The agent uses its Read tool to view the image at startup — Claude Code agents are multimodal and can read image files directly.

Rule: always use /tmp/orchestrator-context-<timestamp>.png as the naming convention so the supervisor knows what to look for if it needs to re-brief an agent with the same image.

Orchestrator final evaluation (YOU decide, not the script)

verify-complete.sh is a gate — it blocks premature marking. But it cannot tell you if the work is actually good. That is YOUR job.

When run-loop marks an agent pending_evaluation and you're notified, do all of these before marking done:

1. Run /pr-test (required, serialized, use TodoWrite to queue)

/pr-test is the only reliable confirmation that the objective is actually met. Run it yourself, not the agent.

When multiple PRs reach pending_evaluation at the same time, use TodoWrite to queue them:

- [ ] /pr-test https://github.com/Significant-Gravitas/AutoGPT/pull/NNNN — <feature description>
- [ ] /pr-test https://github.com/Significant-Gravitas/AutoGPT/pull/MMMM — <feature description>

Run one at a time. Check off as you go.

/pr-test https://github.com/Significant-Gravitas/AutoGPT/pull/PR_NUMBER

/pr-test can be lazy — if it gives vague output, re-run with full context:

/pr-test https://github.com/OWNER/REPO/pull/PR_NUMBER
Context: This PR implements <objective from state file>. Key files: <list>.
Please verify: <specific behaviors to check>.

Only one /pr-test at a time — they share ports and DB.

/pr-test result evaluation

PARTIAL on any headline feature scenario is an immediate blocker. Do not approve, do not mark done, do not let the agent output ORCHESTRATOR:DONE.

/pr-test result	Action
All headline scenarios PASS	Proceed to evaluation step 2
Any headline scenario PARTIAL	Re-brief the agent immediately — see below
Any headline scenario FAIL	Re-brief the agent immediately

What PARTIAL means: the feature is only partly working. Example: the Apply button never appeared, or the AI returned no action blocks. The agent addressed part of the objective but not all of it.

When any headline scenario is PARTIAL or FAIL:

1. Do NOT mark the agent done or accept ORCHESTRATOR:DONE
2. Re-brief the agent with the specific scenario that failed and what was missing:

   tmux send-keys -t SESSION:WIN "PARTIAL result on /pr-test — S5 (Apply button) never appeared. The AI must output JSON action blocks for the Apply button to render. Fix this before re-running /pr-test."
   sleep 0.3
   tmux send-keys -t SESSION:WIN Enter
   

3. Set state back to running:

   jq --arg w "SESSION:WIN" '(.agents[] | select(.window == $w)).state = "running"' \
     ~/.claude/orchestrator-state.json > /tmp/orch.tmp && mv /tmp/orch.tmp ~/.claude/orchestrator-state.json
   

4. Wait for new ORCHESTRATOR:DONE, then re-run /pr-test from scratch

Rule: only ALL-PASS qualifies for approval. A mix of PASS + PARTIAL is a failure.

Why this matters: A PR was once wrongly approved with S5 PARTIAL — the AI never output JSON action blocks so the Apply button never appeared. The fix was already in the agent's reach but slipped through because PARTIAL was not treated as blocking.

2. Do your own evaluation

1. Read the PR diff and objective — does the code actually implement what was asked? Is anything obviously missing or half-done?
2. Read the resolved threads — were comments addressed with real fixes, or just dismissed/resolved without changes?
3. Check CI run names — any suspicious retries that shouldn't have passed?
4. Check the PR description — title, summary, test plan complete?

3. Decide

• /pr-test all scenarios PASS + evaluation looks good → mark done in state, tell the user the PR is ready, ask if window should be closed
• /pr-test any scenario PARTIAL or FAIL → re-brief the agent with the specific failing scenario, set state back to running (see /pr-test result evaluation above)
• Evaluation finds gaps even with all PASS → re-brief the agent with specific gaps, set state back to running

Never mark done based purely on script output. You hold the full objective context; the script does not.

# Mark done after your positive evaluation:
jq --arg w "SESSION:WIN" '(.agents[] | select(.window == $w)).state = "done"' \
  ~/.claude/orchestrator-state.json > /tmp/orch.tmp && mv /tmp/orch.tmp ~/.claude/orchestrator-state.json

When to stop the fleet

Stop the fleet (active = false) when all of the following are true:

Check	How to verify
All agents are done or escalated	`jq '[.agents[]
All PRs have 0 unresolved review threads	GraphQL isResolved check per PR
All PRs have green CI on a run triggered after the agent's last push	gh run list --branch BRANCH --limit 1 timestamp > spawned_at in state
No fresh CHANGES_REQUESTED (after latest commit)	verify-complete.sh checks this — stale pre-commit reviews are ignored
No agents are escalated without human review	If any are escalated, surface to user first

Do NOT stop just because agents output ORCHESTRATOR:DONE. That is a signal to verify, not a signal to stop.

Do stop if the user explicitly says "stop", "shut down", or "kill everything", even with agents still running.

# Graceful stop
jq '.active = false' ~/.claude/orchestrator-state.json > /tmp/orch.tmp \
  && mv /tmp/orch.tmp ~/.claude/orchestrator-state.json

LOOP_WINDOW=$(jq -r '.loop_window // ""' ~/.claude/orchestrator-state.json)
[ -n "$LOOP_WINDOW" ] && tmux kill-window -t "$LOOP_WINDOW" 2>/dev/null || true

Does not recycle running worktrees — agents may still be mid-task. Run capacity.sh to see what's still in progress.

tmux send-keys pattern

Always split long messages into text + Enter as two separate calls with a sleep between them. If sent as one call ("text" Enter), Enter can fire before the full string is buffered into Claude's input — leaving the message stuck as [Pasted text +N lines] unsent.

# CORRECT — text then Enter separately
tmux send-keys -t "$WINDOW" "your long message here"
sleep 0.3
tmux send-keys -t "$WINDOW" Enter

# WRONG — Enter may fire before text is buffered
tmux send-keys -t "$WINDOW" "your long message here" Enter

Short single-character sends (y, Down, empty Enter for dialog approval) are safe to combine since they have no buffering lag.

---

Protected worktrees

Some worktrees must never be used as spare worktrees for agent tasks because they host files critical to the orchestrator itself:

Worktree	Protected branch	Why
AutoGPT1	dx/orchestrate-skill	Hosts the orchestrate skill scripts. recycle-agent.sh would check out spare/1, wiping .claude/skills/ and breaking all subsequent spawn-agent.sh calls.

Rule: when selecting spare worktrees via find-spare.sh, skip any worktree whose CURRENT branch matches a protected branch. If you accidentally spawn an agent in a protected worktree, do not let recycle-agent.sh run on it — manually restore the branch after the agent finishes.

When dx/orchestrate-skill is merged into dev, AutoGPT1 becomes a normal spare again.

Thread resolution integrity (critical)

Agents MUST NOT resolve review threads via GraphQL unless a real code fix has been committed and pushed first.

This is the most common failure mode: agents call resolveReviewThread to make unresolved counts drop without actually fixing anything. This produces a false "done" signal that gets past verify-complete.sh.

The only valid resolution sequence:

1. Read the thread and understand what it's asking
2. Make the actual code change
3. git commit and git push
4. Reply to the thread with the commit SHA (e.g. "Fixed in abc1234")
5. THEN call resolveReviewThread

The supervisor must verify actual thread counts via GraphQL — never trust an agent's claim of "0 unresolved." After any agent's ORCHESTRATOR:DONE, always run:

# Step 1: get total count
TOTAL=$(gh api graphql -f query='{ repository(owner: "OWNER", name: "REPO") { pullRequest(number: PR) { reviewThreads { totalCount } } } }' \
  | jq '.data.repository.pullRequest.reviewThreads.totalCount')
echo "Total threads: $TOTAL"

# Step 2: paginate all pages and count unresolved
CURSOR=""; UNRESOLVED=0
while true; do
  AFTER=${CURSOR:+", after: \"$CURSOR\""}
  PAGE=$(gh api graphql -f query="{ repository(owner: \"OWNER\", name: \"REPO\") { pullRequest(number: PR) { reviewThreads(first: 100${AFTER}) { pageInfo { hasNextPage endCursor } nodes { isResolved } } } } }")
  UNRESOLVED=$(( UNRESOLVED + $(echo "$PAGE" | jq '[.data.repository.pullRequest.reviewThreads.nodes[] | select(.isResolved==false)] | length') ))
  HAS_NEXT=$(echo "$PAGE" | jq -r '.data.repository.pullRequest.reviewThreads.pageInfo.hasNextPage')
  CURSOR=$(echo "$PAGE" | jq -r '.data.repository.pullRequest.reviewThreads.pageInfo.endCursor')
  [ "$HAS_NEXT" = "false" ] && break
done
echo "Unresolved: $UNRESOLVED"

If unresolved > 0, the agent is NOT done — re-brief with the actual count and the rule.

Include this in every agent objective:

IMPORTANT: Do NOT resolve any review thread via GraphQL unless the code fix is committed and pushed first. Fix the code → commit → push → reply with SHA → then resolve. Never resolve without a real commit. "Accepted" or "Acknowledged" replies are NOT resolutions — only real commits qualify.

Detecting fake resolutions

When an agent claims "0 unresolved threads", query GitHub GraphQL yourself and also inspect how each thread was resolved. A resolved thread whose last comment is "Acknowledged", "Same as above", "Accepted trade-off", or "Deferred" — with no commit SHA — is a fake resolution.

To spot these, paginate all pages and collect resolved threads with missing SHA links:

# Paginate all pages — first:100 misses threads beyond page 1 on large PRs
CURSOR=""; FAKE_RESOLUTIONS="[]"
while true; do
  AFTER=${CURSOR:+", after: \"$CURSOR\""}
  PAGE=$(gh api graphql -f query="
  {
    repository(owner: \"Significant-Gravitas\", name: \"AutoGPT\") {
      pullRequest(number: PR_NUMBER) {
        reviewThreads(first: 100${AFTER}) {
          pageInfo { hasNextPage endCursor }
          nodes {
            isResolved
            comments(last: 1) {
              nodes { body author { login } }
            }
          }
        }
      }
    }
  }")
  PAGE_FAKES=$(echo "$PAGE" | jq '[.data.repository.pullRequest.reviewThreads.nodes[]
    | select(.isResolved == true)
    | {body: .comments.nodes[0].body[:120], author: .comments.nodes[0].author.login}
    | select(.body | test("Fixed in|Removed in|Addressed in") | not)]')
  FAKE_RESOLUTIONS=$(echo "$FAKE_RESOLUTIONS $PAGE_FAKES" | jq -s 'add')
  HAS_NEXT=$(echo "$PAGE" | jq -r '.data.repository.pullRequest.reviewThreads.pageInfo.hasNextPage')
  CURSOR=$(echo "$PAGE" | jq -r '.data.repository.pullRequest.reviewThreads.pageInfo.endCursor')
  [ "$HAS_NEXT" = "false" ] && break
done
echo "$FAKE_RESOLUTIONS"

Any resolved thread whose last comment does NOT contain "Fixed in", "Removed in", or "Addressed in" (with a commit link) should be investigated — either the agent falsely resolved it, or it was a genuine false positive that needs explanation.

GitHub abuse rate limits

Two distinct rate limits exist with different recovery times:

Error	HTTP status	Cause	Recovery
{"code":"abuse"} in body	403	Secondary rate limit — too many write operations (comments, mutations) in a short window	Wait 2–3 minutes. 60s is often not enough.
API rate limit exceeded	429	Primary rate limit — too many read calls per hour	Wait until X-RateLimit-Reset timestamp

Prevention: Agents must add sleep 3 between individual thread reply API calls. For >20 unresolved threads, increase to sleep 5.

If you see a 403 abuse error from an agent's pane:

1. Nudge the agent: "You hit a GitHub secondary rate limit (403). Stop all API writes. Wait 2 minutes, then resume with sleep 3 between each thread reply."
2. Do NOT nudge again during the 2-minute wait — a second nudge restarts the clock.

Add this to agent briefings when there are >20 unresolved threads:

Post replies with sleep 3 between each reply. If you hit a 403 abuse error, wait 2 minutes (not 60s — secondary limits take longer to clear) then continue.

Key rules

1. Scripts do all the heavy lifting — don't reimplement their logic inline in this file
2. Never ask the user to pick a worktree — auto-assign from find-spare.sh output
3. Never restart a running agent — only restart on idle kicks (foreground is a shell)
4. Auto-dismiss settings dialogs — if "Enter to confirm" appears, send Down+Enter
5. Always --permission-mode bypassPermissions on every spawn
6. Escalate after 3 kicks — mark escalated, surface to user
7. Atomic state writes — always write to .tmp then mv
8. Never approve destructive commands outside the worktree scope — when in doubt, escalate
9. Never recycle without verification — verify-complete.sh must pass before recycling
10. No TASK.md files — commit risk; use state file + gh pr view for agent context persistence
11. Re-brief stalled agents — read objective from state file + gh pr view, send via tmux
12. ORCHESTRATOR:DONE is a signal to verify, not to accept — always run verify-complete.sh and check CI run timestamp before recycling
13. Protected worktrees — never use the worktree hosting the skill scripts as a spare
14. Images via file path — save screenshots to /tmp/orchestrator-context-<ts>.png, pass path in objective; agents read with the Read tool
15. Split send-keys — always separate text and Enter with sleep 0.3 between calls for long strings
16. Poll ALL windows from state file — never hardcode window count. Derive active windows dynamically: jq -r '.agents[] | select(.state | test("running|idle|stuck")) | .window' ~/.claude/orchestrator-state.json. If you added a window mid-session outside spawn-agent.sh, add it to the state file immediately.
17. Orchestrator handles its own approvals — when spawning a subagent to make edits (SKILL.md, scripts, config), review the diff yourself and approve/reject without surfacing it to the user. The user should never have to open a file to check the orchestrator's work. Use the Agent tool with subagent_type: general-purpose for drafting, then verify the result yourself before considering the task done.
