Install
Arbiter Skill
Push decisions to Arbiter Zebu for async human review. Use when you need human input on plans, architectural choices, or approval before proceeding.
Installation
Quick install via ClawHub:
clawhub install arbiterOr via bun (makes CLI commands available globally):
bun add -g arbiter-skillOr manual:
git clone https://github.com/5hanth/arbiter-skill.git
cd arbiter-skill && npm install && npm run build
ln -s $(pwd) ~/.clawdbot/skills/arbiterPrerequisites
- Arbiter Zebu bot running (or just
bunx arbiter-zebu) ~/.arbiter/queue/directory (created automatically by the bot)
Environment Variables
Set these in your agent's environment for automatic agent/session detection:
| Variable | Description | Example |
|---|---|---|
CLAWDBOT_AGENT | Agent ID | ceo, swe1 |
CLAWDBOT_SESSION | Session key | agent:ceo:main |
When to Use
- Plan review before implementation
- Architectural decisions with tradeoffs
- Anything blocking that needs human judgment
- Multiple related decisions as a batch
Do NOT use for:
- Simple yes/no that doesn't need explanation
- Urgent real-time decisions (use direct message instead)
- Technical questions you can research yourself

Returns:
{
"planId": "abc123",
"file": "~/.arbiter/queue/pending/ceo-api-design-abc123.md",
"total": 2,
"status": "pending"
}arbiter_status
Check the status of a decision plan.
CLI: arbiter-status <plan-id> or arbiter-status --tag <tag>
arbiter-status abc12345
# or
arbiter-status --tag nft-marketplaceReturns:
{
"planId": "abc123",
"title": "API Design Decisions",
"status": "in_progress",
"total": 3,
"answered": 1,
"remaining": 2,
"decisions": {
"auth-strategy": {"status": "answered", "answer": "jwt"},
"database": {"status": "pending", "answer": null},
"caching": {"status": "pending", "answer": null}
}
}arbiter_get
Get answers from a completed plan.
CLI: arbiter-get <plan-id> or arbiter-get --tag <tag>
arbiter-get abc12345
# or
arbiter-get --tag nft-marketplaceReturns:
{
"planId": "abc123",
"status": "completed",
"completedAt": "2026-01-30T01:45:00Z",
"answers": {
"auth-strategy": "jwt",
"database": "postgresql",
"caching": "redis"
}
}Error if not complete:
{
"error": "Plan not complete",
"status": "in_progress",
"remaining": 2
}arbiter_await
Block until plan is complete (with timeout).
arbiter-await abc12345 --timeout 3600Polls every 30 seconds until complete or timeout.
Returns: Same as arbiter_get on completion.
Usage Examples
Example 1: Plan Review
# Push plan decisions (single JSON argument)
RESULT=$(arbiter-push '{"title":"Clean IT i18n Plan","tag":"clean-it","priority":"high","notify":"agent:swe3:main","decisions":[{"id":"library","title":"i18n Library","options":[{"key":"i18next","label":"i18next"},{"key":"formatjs","label":"FormatJS"}]},{"id":"keys","title":"Key Structure","options":[{"key":"flat","label":"Flat (login.button)"},{"key":"nested","label":"Nested ({login:{button}})"}]}]}')
PLAN_ID=$(echo $RESULT | jq -r '.planId')
echo "Pushed plan $PLAN_ID — waiting for human review"Example 2: Check and Proceed
# Check if decisions are ready
STATUS=$(arbiter-status --tag nft-marketplace)
if [ "$(echo $STATUS | jq -r '.status')" == "completed" ]; then
ANSWERS=$(arbiter-get --tag nft-marketplace)
AUTH=$(echo $ANSWERS | jq -r '.answers["auth-strategy"]')
echo "Using auth strategy: $AUTH"
# Proceed with implementation
else
echo "Still waiting for $(echo $STATUS | jq -r '.remaining') decisions"
fiExample 3: Blocking Wait
# Wait up to 1 hour for decisions
ANSWERS=$(arbiter-await abc12345 --timeout 3600)
if [ $? -eq 0 ]; then
# Got answers, proceed
echo "Decisions ready: $ANSWERS"
else
echo "Timeout waiting for decisions"
fiBest Practices
- Batch related decisions — Don't push one at a time
- Provide context — Human needs to understand tradeoffs
- Use tags — Makes filtering easy (
--tag project-name) - Set notify — So blocked agents get woken up
- Use priority sparingly — Reserve
urgentfor true blockers
File Locations
| Path | Purpose |
|---|---|
~/.arbiter/queue/pending/ | Plans awaiting review |
~/.arbiter/queue/completed/ | Answered plans (archive) |
~/.arbiter/queue/notify/ | Agent notifications |
Checking Notifications (Agent Heartbeat)
In your HEARTBEAT.md, add:
## Check Arbiter Notifications
1. Check if `~/.arbiter/queue/notify/` has files for my session
2. If yes, read answers and proceed with blocked work
3. Delete notification file after processingTroubleshooting
| Issue | Solution |
|---|---|
| Plan not showing in Arbiter | Check file is valid YAML frontmatter |
| Answers not appearing | Check arbiter_status, may be incomplete |
| Notification not received | Ensure --notify was set correctly |
