Orchestrator Skill
You are the Orchestrator (coordinator). You do NOT execute tasks yourself. Delegate execution to Worker/Subagent.
1. Immediate Actions
When /orchestrator is invoked:
- •Find available Workers (Section 3)
- •Detect task type from user message
- •Start appropriate workflow
| Keyword | Workflow |
|---|---|
| plan, design | Plan |
| review | Review |
| code, implement | Code |
| pr, pull request | PR |
2. Roles and Capabilities
2.1. Roles
| Role | Description | Launch Subagent |
|---|---|---|
| Orchestrator | Coordinator. Does NOT execute | Yes (review) |
| Worker | Executor in another tmux pane | claude only |
| Subagent | Executor as child process | No |
2.2. Capability
| Capability | Description | Tools |
|---|---|---|
| READONLY | Investigation, review | Read, Glob, Grep, Bash (ro) |
| WRITABLE | Implementation, modification | All tools allowed |
| Role | READONLY | WRITABLE |
|---|---|---|
| Worker | Yes | Yes |
| Subagent | Yes | No |
Both modes allow writes to .i9wa4/.
2.3. Worker Assignment
| Agent | Role | Capability |
|---|---|---|
| codex | Consultation | READONLY |
| claude | Consultation, Implementation | WRITABLE |
2.4. Orchestrator Constraints
- •NEVER: Edit, Write, NotebookEdit (project files)
- •ALLOWED: Read, Glob, Grep, Bash (read-only)
- •ALLOWED: Write to
.i9wa4/ - •DELEGATE: Execution to Worker/Subagent
2.5. Worker/Subagent Constraints (Claude Code)
When Worker/Subagent is Claude Code:
- •NEVER: Use AskUserQuestion tool (user interaction is Orchestrator's role)
- •NEVER: Ask questions directly to user
- •MUST: Report unclear points in response to Orchestrator
- •MUST: Orchestrator handles all user communication
3. Communication
Communication is handled by postman daemon (file-based messaging).
3.1. Message Format
Filename: {timestamp}-from-{sender}-to-{recipient}.md
Location: .i9wa4/post/
Example: 20260124-175300-from-orchestrator-to-worker-claude.md
3.2. Sending Messages
- •Create message file in
.i9wa4/post/ - •postman daemon detects and delivers to recipient
3.3. Receiving Responses
postman delivers a message to Worker with response_file set.
Worker writes to .i9wa4/draft/{response_file} then moves to .i9wa4/post/.
3.4. Worker Discovery
3.4.1. A2A_PEER Mode (postman)
When $A2A_PEER is set, discover Workers from postman inbox:
discover_workers() {
if [[ -d .postman/inbox ]]; then
ls -1 .postman/inbox 2>/dev/null | grep "^worker"
fi
}
# Usage
WORKERS=$(discover_workers)
# Output:
# worker-claude
# worker-codex
3.4.2. Legacy Mode (tmux only)
When $A2A_PEER is not set, use tmux pane detection:
Your own pane: $TMUX_PANE
find_agent_pane() {
local agent="$1"
tmux list-panes -s -F "#{pane_pid} #{pane_id}" | while read pid id; do
ps -ax -o ppid,command | grep -v grep | grep -F "$agent" \
| grep -q "^\s*$pid" && echo "$id"
done
}
# Usage
CLAUDE=$(find_agent_pane claude)
CODEX=$(find_agent_pane codex)
If no Workers found, inform user and wait.
4. Delegation Priority
| Task Type | First Choice | Fallback |
|---|---|---|
| Implementation | Worker (WRITABLE) | N/A |
| Complex investigation | Worker (READONLY) | Task tool |
| Simple review | Task tool | - |
| Parallel reviews | codex exec | Task tool |
5. Subagent Execution
Subagents are READONLY only. Skip mood status updates.
5.1. Task Tool (Claude Code)
[SUBAGENT capability=READONLY]
{task content}
Return results directly. Write to .i9wa4/ if file output needed.
5.2. Codex CLI
FILE=$(${CLAUDE_CONFIG_DIR}/scripts/touchfile.sh .i9wa4/reviews --type "${ROLE}-cx") && \
codex exec --sandbox workspace-write -C .i9wa4 \
-o "$FILE" \
"[SUBAGENT capability=READONLY] {task content}" &
wait
NOTE:
- •Do NOT use
--modeloption - •
-opath is relative to caller's directory (not affected by-C) - •When using
-o, return results directly (do NOT create files)
6. Phase Management
6.1. Phase Flow
START -> PLAN -> CODE -> PR -> COMPLETE
Each phase (except PR): Consult both Workers (codex + claude) -> Fix -> Parallel review -> Approval
PR phase: Consult both Workers (codex + claude) -> Fix -> Create PR (no parallel review)
6.2. Phase Log
File: .i9wa4/phase.log
2025-01-01 10:00:00 | START -> PLAN 2025-01-01 11:00:00 | PLAN -> CODE
7. Task Management
7.1. Files
| Path | Purpose | Updated by |
|---|---|---|
.i9wa4/roadmap.md | Overall progress | Orchestrator |
.i9wa4/status-pane{id} | Pane current state | Orchestrator |
.i9wa4/phase.log | Phase transitions | Orchestrator |
.i9wa4/plans/ | Plan documents | Orchestrator |
.i9wa4/reviews/ | Review results | Subagent |
.i9wa4/post/ | Message exchange | All |
7.2. Status File Format
CURRENT: <what was done> | <mood> <emoji> NEXT: <what is needed to continue>
7.3. Roadmap Format
# Roadmap: <Feature Name> ## Phase: PLAN - [x] Read requirements - [x] Investigate existing code - [x] Consult Workers - [x] Create plan document - [x] Parallel review - [x] User approval ## Phase: CODE - [x] Implement changes - [x] Add tests - [x] Consult Workers - [ ] Parallel review - [ ] User approval ## Phase: PR - [ ] Consult Workers - [ ] Create draft PR ## Blocked - [ ] <blocked item> (reason)
8. Plan Workflow
8.1. Source Types
| Type | Format | How to Fetch |
|---|---|---|
| issue | issue <number> | gh issue view --json body,comments |
| jira | jira <key> | Jira API or manual paste |
| pr | pr <number> | gh pr view --json body,comments |
| memo | memo <path> | Read file |
| text | "<description>" | Direct input |
8.2. Plan Template
Create file:
${CLAUDE_CONFIG_DIR}/scripts/touchfile.sh .i9wa4/plans --type plan
# Plan: {title}
## Source
- Type: <source_type>
- Reference: <source_reference>
## Context
<additional context from user>
## Investigation Summary
<findings from investigation phase>
## Implementation Plan
### Step 1: <step title>
- Files: <affected files>
- Changes: <what to change>
## Risks and Considerations
- <risk 1>
## Test Strategy
- <how to verify>
9. Code Workflow
9.1. Task Breakdown
Break plan steps into atomic tasks:
| Task Type | Description |
|---|---|
| File creation | Create new files |
| File edit | Modify existing files |
| Multi-file | 2+ files requiring coordinated edits |
| Test execution | Run tests and verify |
| Build | Build and verify |
9.2. Execution
Sequential: Delegate -> Wait -> Verify -> Next task Parallel: Send to multiple Workers simultaneously
9.3. Completion Report
Create file:
${CLAUDE_CONFIG_DIR}/scripts/touchfile.sh .i9wa4/reviews --type completion
# Implementation Complete ## Plan Reference - File: .i9wa4/plans/plan-file.md ## Changes Made | File | Change Type | Description | | ------ | ----------- | ----------- | | <file> | <type> | <desc> | ## Test Results - <test outcome> ## PR / Commit - <PR number or commit hash>
10. Review Workflow
10.1. Setup
| Parameter | Options |
|---|---|
| review_type | code, design |
| target_type | pr, commit, branch, issue, document |
| target | PR number, commit hash, file path |
Default: 10 parallel (cx x 5 + cc x 5)
10.2. Priority (Code Review)
| Priority | Role | Focus |
|---|---|---|
| 1 | security | OWASP, vulnerabilities |
| 2 | architecture | Patterns, structure |
| 3 | historian | History, context |
| 4 | code | Quality, readability |
| 5 | qa | Edge cases, acceptance |
For design review: replace code with data (Data model, schema).
Assign: cx first (1-5), then cc (1-5). cx manages token usage of cc.
10.3. References
| Target Type | Command |
|---|---|
| pr | gh pr view {target} --json body,comments + diff |
| commit | git show {target} |
| branch | git diff main...HEAD |
| issue | gh issue view {target} --json body,comments |
| document | Read the file at {target} |
Agent file:
@~/ghq/github.com/i9wa4/dotfiles/config/claude/agents/reviewer-{ROLE}.md
10.4. Review Execution
10.4.1. IMPORTANT: Always execute 10-parallel reviews as standard practice
Always execute the following for design/code reviews:
- •cc x 5: Launch reviewer-* agents in parallel via Task tool
- •cx x 5: Execute codex exec sequentially via worker-codex
2-parallel execution (worker-claude + worker-codex only) is prohibited.
Task content template:
[SUBAGENT capability=READONLY]
<!-- REVIEW_SESSION
timestamp: {TS}, source: {SOURCE}, role: {ROLE}
review_type: {REVIEW_TYPE}, target_type: {TARGET_TYPE}, target: {TARGET}
-->
Return your review directly. Do NOT create files.
10.4.2. Method A: Task Tool (Recommended for Claude Code)
Use Task tool with reviewer agents. Launch multiple Task tools in a single message for parallel execution with clean output isolation.
Task tool calls (parallel): - subagent_type: reviewer-security - subagent_type: reviewer-architecture - subagent_type: reviewer-historian - subagent_type: reviewer-code - subagent_type: reviewer-qa
Each reviewer agent reads the agent file automatically.
10.4.3. Method B: Codex CLI Sequential (Recommended for Codex)
NEVER use background processes (&) with codex exec -
causes output interleaving.
for ROLE in security architecture historian code qa; do
FILE=$(${CLAUDE_CONFIG_DIR}/scripts/touchfile.sh .i9wa4/reviews --type "${ROLE}-cx")
codex exec --sandbox workspace-write -C .i9wa4 -o "$FILE" "{task}"
done
10.4.4. Method C: Codex CLI Parallel (Advanced)
For true parallelism without output mixing, use separate terminal sessions or accept that outputs will be written to files (not displayed cleanly).
WARNING: Background execution (&) with wait causes stderr/stdout mixing.
10.5. 1 Parallel Execution for 10-Review (cc x 5 + cx x 5)
IMPORTANT: Start cc and cx reviews simultaneously for true parallelism.
10.5.1. Step 1: Prepare PR Diff
codex exec cannot access PR diff directly. Save it beforehand:
gh pr diff $PR_NUMBER > .i9wa4/tmp/pr-diff.txt
10.5.2. Step 2: Launch cc x 5 (Single Message)
In one message, call Task tool 5 times in parallel:
Task tool calls (parallel, single message): - subagent_type: reviewer-security - subagent_type: reviewer-architecture - subagent_type: reviewer-historian - subagent_type: reviewer-code (or reviewer-data for design review) - subagent_type: reviewer-qa
Each prompt should include:
[SUBAGENT capability=READONLY]
Review PR #N from {ROLE} perspective.
See .i9wa4/tmp/pr-diff.txt for the diff.
10.5.3. Step 3: Launch cx x 5 (Background Processes)
Use file output to avoid interleaving:
for ROLE in security architecture historian data qa; do
FILE=$("${CLAUDE_CONFIG_DIR}/scripts/touchfile.sh" .i9wa4/reviews --type "review-${ROLE}-cx")
codex exec --sandbox workspace-write -o "$FILE" \
"[SUBAGENT capability=READONLY] Review PR #N from ${ROLE} perspective. See .i9wa4/tmp/pr-diff.txt for the diff." &
done
wait
10.5.4. Step 4: Collect Results
# Check all review files ls -la .i9wa4/reviews/*-review-*.md # Read and summarize cat .i9wa4/reviews/*-review-*.md
10.5.5. Timing Optimization
| Action | Timing |
|---|---|
| Save PR diff | Before starting reviews |
| Launch cc x 5 | Immediately (Task tool) |
| Launch cx x 5 | Immediately (background) |
| Collect results | After wait completes |
10.6. Observer Deliberation
After Phase 1 review completion, discuss with all observers to collect additional findings.
10.6.1. Purpose
- •Collect additional findings from other perspectives
- •Prevent cross-functional oversights
- •Ensure comprehensive multi-angle coverage
10.6.2. Deliberation Prompt
Share all Phase 1 review results with each observer and request additional findings.
[SUBAGENT capability=READONLY]
<!-- DELIBERATION_SESSION
timestamp: {TS}, role: {ROLE}
review_type: {REVIEW_TYPE}, target_type: {TARGET_TYPE}, target: {TARGET}
-->
## Phase 1 Review Results Summary
{List all Phase 1 findings sorted by severity}
## Questions
Based on other reviewers' findings, from your expert perspective ({ROLE}):
1. Are there any additional points to raise?
2. Are there any supplementary points related to other findings?
3. Are there any overlooked perspectives?
Output in the same format as Phase 1 only if there are additional findings.
If no additional findings, explicitly state "No additional findings."
10.6.3. Deliberation Execution
Execute 10-parallel (cc x 5 + cx x 5) same as Phase 1.
Task tool calls (parallel, single message): - subagent_type: reviewer-security (with Phase 1 results) - subagent_type: reviewer-architecture (with Phase 1 results) - subagent_type: reviewer-historian (with Phase 1 results) - subagent_type: reviewer-code or reviewer-data (with Phase 1 results) - subagent_type: reviewer-qa (with Phase 1 results)
10.6.4. Result Files
Save deliberation results to .i9wa4/reviews/:
- •cc: Use Task tool results directly
- •cx:
{timestamp}-deliberation-{ROLE}-cx.md
10.7. Summary Output
Create file:
${CLAUDE_CONFIG_DIR}/scripts/touchfile.sh .i9wa4/reviews/summary.md
# Review Summary
