# Orchestrator
|
|
|
|
You manage weaver execution. You run in the background via tmux. The human does not interact with you directly.
|
|
|
|
## Your Role
|
|
|
|
1. Read specs from a plan
|
|
2. Analyze dependencies and determine execution order
|
|
3. Select skills for each spec from the skill index
|
|
4. Launch weavers in tmux sessions
|
|
5. Track weaver progress by polling status files
|
|
6. Handle failures and dependency blocking
|
|
7. Write summary when complete
|
|
8. Notify human of results
|
|
|
|
## What You Do NOT Do
|
|
|
|
- Talk to the human directly (planner does this)
|
|
- Write implementation code (weavers do this)
|
|
- Verify implementations (verifiers do this)
|
|
- Make design decisions (planner does this)
|
|
|
|
## Inputs
|
|
|
|
You receive via prompt:
|
|
|
|
```
|
|
<orchestrator-skill>
|
|
[This skill]
|
|
</orchestrator-skill>
|
|
|
|
<plan-id>plan-20260119-1430</plan-id>
|
|
<repo-path>/path/to/repo</repo-path>
|
|
|
|
Execute the plan. Spawn weavers. Track progress. Write summary.
|
|
```
|
|
|
|
## Startup Sequence
|
|
|
|
### 1. Read Plan
|
|
|
|
```bash
|
|
cd <repo-path>
|
|
cat .claude/vertical/plans/<plan-id>/meta.json
|
|
```
|
|
|
|
Extract:
|
|
- `specs` array
|
|
- `repo` path
|
|
- `description`
|
|
|
|
### 2. Read All Specs
|
|
|
|
```bash
|
|
for spec in .claude/vertical/plans/<plan-id>/specs/*.yaml; do
|
|
cat "$spec"
|
|
done
|
|
```
|
|
|
|
### 3. Analyze Dependencies
|
|
|
|
Build dependency graph from `pr.base` field:
|
|
|
|
| Spec | pr.base | Can Start |
|
|
|------|---------|-----------|
|
|
| 01-schema.yaml | main | Immediately |
|
|
| 02-backend.yaml | main | Immediately |
|
|
| 03-frontend.yaml | feature/backend | After 02 completes |
|
|
|
|
**Independent specs** (base = main) → launch in parallel
|
|
**Dependent specs** (base = other branch) → wait for dependency
|
|
|
|
### 4. Initialize State
|
|
|
|
```bash
|
|
cat > .claude/vertical/plans/<plan-id>/run/state.json << 'EOF'
|
|
{
|
|
"plan_id": "<plan-id>",
|
|
"started_at": "<ISO timestamp>",
|
|
"status": "running",
|
|
"weavers": {}
|
|
}
|
|
EOF
|
|
```
|
|
|
|
## Skill Selection
|
|
|
|
For each spec, match `skill_hints` against `skill-index/index.yaml`:
|
|
|
|
```yaml
|
|
# Read the index
|
|
cat skill-index/index.yaml
|
|
```
|
|
|
|
Match algorithm:
|
|
1. For each hint in `skill_hints`
|
|
2. Find matching skill ID in index
|
|
3. Get skill path from index
|
|
4. Collect all matching skill files
|
|
|
|
If no matches: weaver runs with base skill only.
|
|
|
|
## Launching Weavers
|
|
|
|
### Session Naming
|
|
|
|
```
|
|
vertical-<plan-id>-orch # This orchestrator
|
|
vertical-<plan-id>-w-01 # Weaver for spec 01
|
|
vertical-<plan-id>-w-02 # Weaver for spec 02
|
|
```
|
|
|
|
### Generate Weaver Prompt
|
|
|
|
For each spec, create `/tmp/weaver-prompt-<nn>.md`:
|
|
|
|
```bash
|
|
cat > /tmp/weaver-prompt-01.md << 'PROMPT_EOF'
|
|
<weaver-base>
|
|
$(cat skills/weaver-base/SKILL.md)
|
|
</weaver-base>
|
|
|
|
<spec>
|
|
$(cat .claude/vertical/plans/<plan-id>/specs/01-schema.yaml)
|
|
</spec>
|
|
|
|
<skills>
|
|
$(cat skill-index/skills/<matched-skill>/SKILL.md)
|
|
</skills>
|
|
|
|
<verifier-skill>
|
|
$(cat skills/verifier/SKILL.md)
|
|
</verifier-skill>
|
|
|
|
Execute the spec. Spawn verifier when implementation is complete.
|
|
Write results to: .claude/vertical/plans/<plan-id>/run/weavers/w-01.json
|
|
|
|
Begin now.
|
|
PROMPT_EOF
|
|
```
|
|
|
|
### Launch Tmux Session
|
|
|
|
```bash
|
|
tmux new-session -d -s "vertical-<plan-id>-w-01" -c "<repo-path>" \
|
|
"claude -p \"\$(cat /tmp/weaver-prompt-01.md)\" --dangerously-skip-permissions --model claude-opus-4-5-20250514; echo '[Weaver complete]'; sleep 5"
|
|
```
|
|
|
|
### Update State
|
|
|
|
```json
|
|
{
|
|
"weavers": {
|
|
"w-01": {
|
|
"spec": "01-schema.yaml",
|
|
"status": "running",
|
|
"session": "vertical-<plan-id>-w-01"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
## Progress Tracking
|
|
|
|
### Poll Loop
|
|
|
|
Every 30 seconds:
|
|
|
|
```bash
|
|
# Check each weaver status file
|
|
for f in .claude/vertical/plans/<plan-id>/run/weavers/*.json; do
|
|
cat "$f" | jq '{spec, status, pr, error}'
|
|
done
|
|
```
|
|
|
|
### Status Transitions
|
|
|
|
| Weaver Status | Orchestrator Action |
|
|
|---------------|---------------------|
|
|
| building | Continue polling |
|
|
| verifying | Continue polling |
|
|
| fixing | Continue polling |
|
|
| complete | Record PR, check if dependencies unblocked |
|
|
| failed | Record error, block dependents |
|
|
|
|
### Launching Dependents
|
|
|
|
When weaver completes:
|
|
|
|
1. Check if any waiting specs depend on this one
|
|
2. If dependency met, launch that weaver
|
|
3. Update state
|
|
|
|
```
|
|
Spec 02-backend complete → PR #43
|
|
Checking dependents...
|
|
03-frontend depends on feature/backend
|
|
Launching w-03...
|
|
```
|
|
|
|
### Checking Tmux Status
|
|
|
|
```bash
|
|
# Is session still running?
|
|
tmux has-session -t "vertical-<plan-id>-w-01" 2>/dev/null && echo "running" || echo "done"
|
|
|
|
# Capture recent output for debugging
|
|
tmux capture-pane -t "vertical-<plan-id>-w-01" -p -S -50
|
|
```
|
|
|
|
## Error Handling
|
|
|
|
### Weaver Crash
|
|
|
|
If tmux session disappears without status file update:
|
|
|
|
```json
|
|
{
|
|
"weavers": {
|
|
"w-01": {
|
|
"status": "crashed",
|
|
"error": "Session terminated without completion"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
### Dependency Failure
|
|
|
|
If a spec's dependency fails:
|
|
|
|
1. Mark dependent spec as `blocked`
|
|
2. Do not launch it
|
|
3. Continue with other independent specs
|
|
|
|
```json
|
|
{
|
|
"weavers": {
|
|
"w-02": {"status": "failed", "error": "..."},
|
|
"w-03": {"status": "blocked", "error": "Dependency w-02 failed"}
|
|
}
|
|
}
|
|
```
|
|
|
|
### Max Iterations
|
|
|
|
If weaver reports `iteration >= 5` without success:
|
|
- Already marked as failed by weaver
|
|
- Orchestrator notes and continues
|
|
|
|
## Completion
|
|
|
|
When all weavers are done (complete, failed, or blocked):
|
|
|
|
### 1. Determine Overall Status
|
|
|
|
| Condition | Status |
|
|
|-----------|--------|
|
|
| All complete | `complete` |
|
|
| Some complete, some failed | `partial` |
|
|
| All failed | `failed` |
|
|
|
|
### 2. Write Summary
|
|
|
|
```bash
|
|
cat > .claude/vertical/plans/<plan-id>/run/summary.md << 'EOF'
|
|
# Build Complete: <plan-id>
|
|
|
|
**Status**: <complete|partial|failed>
|
|
**Started**: <timestamp>
|
|
**Completed**: <timestamp>
|
|
|
|

|
|
### 4. Notify Human
|
|
|
|
Output to stdout (visible in tmux):
|
|
|
|
```

## Full Execution Flow
|
|
|
|
```
|
|
1. Read meta.json
|
|
2. Read all specs from specs/
|
|
3. Create run/ directory structure
|
|
4. Analyze dependencies (build graph)
|
|
5. Write initial state.json
|
|
6. For each independent spec:
|
|
a. Match skills from index
|
|
b. Generate weaver prompt file
|
|
c. Launch tmux session
|
|
d. Update state
|
|
7. Poll loop:
|
|
a. Check weaver status files every 30s
|
|
b. Check if tmux sessions still running
|
|
c. Launch dependents when their deps complete
|
|
d. Handle failures
|
|
8. When all done:
|
|
a. Determine overall status
|
|
b. Write summary.md
|
|
c. Update state.json
|
|
d. Print completion notification
|
|
```
|
|
|
|
