recursive-communicator（递归通讯器）

Purpose

The recursive-communicator skill provides structured protocols for managing recursive communication loops between the validation orchestrator, validation specialists, and the main feature implementer agent. It handles failure notifications, fix requests, re-validation triggers, and loop termination to ensure validation issues are resolved systematically.

When to Use

This skill auto-activates when you:

• Communicate validation failures to the main agent
• Request fixes from the main agent for validation issues
• Trigger re-validation after main agent fixes
• Manage recursive fix loops (failure → fix → re-check → repeat)
• Track iteration counts in recursive communication
• Prevent deadlocks in recursive loops
• Escalate unresolvable validation issues
• Log communication history for traceability

Provided Capabilities

1. Failure Communication

• Structured Failure Reports: Format validation failures for main agent
• Detailed Error Information: Include file locations, line numbers, error messages
• Suggested Fixes: Provide specialist recommendations for resolving issues
• Priority Tagging: Mark critical vs. non-critical failures
• Context Preservation: Include all relevant context for debugging

2. Fix Request Management

• Clear Fix Requests: Explicitly request main agent to fix specific issues
• Action Items: Provide actionable list of fixes needed
• Deadline Awareness: Track iteration limits (max 5)
• Fix Verification: Confirm when main agent completes fixes
• Re-validation Triggering: Signal specialists to re-check after fixes

3. Re-validation Coordination

• Re-check Signals: Trigger specialist re-validation after fixes
• Iteration Tracking: Increment and track iteration counts
• Status Updates: Communicate re-validation status to all parties
• Loop Continuation: Determine if another iteration needed
• Loop Termination: Identify when to exit recursive loop

4. Deadlock Prevention

• Max Iteration Limits: Enforce maximum 5 iterations per specialist
• Timeout Detection: Identify stalled communication
• Escalation Triggers: Escalate after max iterations or timeout
• User Intervention Requests: Flag when human input needed
• Graceful Degradation: Handle unresolvable issues without blocking workflow

5. Communication Logging

• Message History: Log all communication between agents
• Iteration History: Track all iterations with timestamps
• Fix History: Document all fixes attempted
• Status Transitions: Log status changes (failed → fixing → re-checking → passed)
• Audit Trail: Maintain complete communication audit trail

Usage Guide

Step 1: Detect Validation Failure

When a validation specialist reports failure:

**Validation Failure Detected**

**Specialist**: test-runner-specialist
**Phase**: Test Execution
**Issue**: 3 unit tests failing

**Failure Details**:
- test_validation_coordinator.py::test_sequential_invocation - AssertionError
- test_validation_coordinator.py::test_failure_tracking - KeyError

5. IF max iterations exceeded: Escalate to user intervention

---

**Sent by**: Validation Orchestrator (recursive-communicator skill)
**Awaiting**: Main Agent Fix Completion

Step 3: Send Failure Report to Main Agent

Communicate failure report to @feature-implementer-main:

Communication Protocol:

### Sending Failure Report

**To**: @feature-implementer-main
**From**: @validation-orchestrator (via recursive-communicator)
**Type**: Validation Failure Report
**Priority**: [High/Medium/Low based on severity]

**Message**:
---
@feature-implementer-main: Validation failure detected during [Phase] validation.

[Full Failure Report from Step 2]

Please review and fix the above issues. Signal completion when ready for re-validation.
---

**Status**: Sent
**Timestamp**: [YYYY-MM-DD HH:MM:SS]
**Awaiting Response**: Yes

Step 4: Wait for Main Agent Fix

Monitor main agent activity:

Waiting State:

### Awaiting Main Agent Fix

**Current Status**: Waiting for Fix
**Specialist**: [Specialist Name] (paused)
**Iteration**: [Current] / [Max (5)]
**Time Elapsed**: [MM:SS since failure report sent]
**Timeout**: 30 minutes (escalate if exceeded)

**Main Agent Actions Expected**:
- [ ] Review failure report
- [ ] Analyze failure root causes
- [ ] Implement fixes
- [ ] Verify fixes locally (optional)
- [ ] Signal completion to validation orchestrator

**Monitoring**:
- Check main agent status every 2 minutes
- Log any main agent communications
- Detect timeout if >30 minutes without response

Timeout Handling:

IF time_elapsed > 30 minutes WITHOUT main agent response:
  1. Log timeout event
  2. Send reminder to main agent
  3. IF still no response after reminder (5 minutes):
     a. Escalate to user intervention
     b. Flag as "unresponsive"
     c. Await user decision (abort / manual fix / extend timeout)

Step 5: Receive Fix Completion Signal

When main agent signals fix completion:

Fix Completion Confirmation:

### Main Agent Fix Completed

**Received From**: @feature-implementer-main
**Timestamp**: [YYYY-MM-DD HH:MM:SS]
**Fix Duration**: [MM:SS from failure report to completion]

**Main Agent Report**:
[Summary of fixes implemented by main agent]

**Fixes Applied**:
- Fix 1: [Description of fix]
- Fix 2: [Description of fix]
- [... Additional fixes ...]

**Verification**:
- [ ] Main agent confirmed fixes applied
- [ ] Files modified: [List of changed files]
- [ ] Ready for re-validation

**Next Action**: Trigger re-validation (Step 6)

Step 6: Trigger Re-validation

Re-invoke specialist for re-check:

Re-validation Trigger:

### Triggering Re-validation

**Specialist**: [Specialist Name]
**Iteration**: [Current+1] / [Max (5)]
**Previous Status**: Failed
**Current Status**: Re-checking

**Re-invocation**:
@[specialist-name] re-check [validation type] for feature #{issue-number}
Iteration: [Current+1] / [Max (5)]
Previous failures: [List of failures from previous iteration]
Fixes applied: [List of fixes from main agent]

**Expected Outcomes**:
1. **PASS**: All previous failures resolved
   - Exit recursive loop
   - Proceed to next validation phase
   - Log success with iteration count

2. **FAIL** (some/all failures persist):
   - Increment iteration count
   - Return to Step 1 (detect failure)
   - IF iteration <= 5: Repeat recursive loop
   - IF iteration > 5: Escalate (Step 7)

**Status**: Re-validation in Progress
**Timestamp**: [YYYY-MM-DD HH:MM:SS]

Step 7: Handle Re-validation Result

Process specialist re-check output:

Result: PASS ✅

### Re-validation Success

**Specialist**: [Specialist Name]
**Iteration**: [Final] / [Max (5)]
**Status**: ✅ PASSED

**Previous Failures**: [Count] failures
**Current Failures**: 0 failures
**Resolution**: All issues fixed by main agent

**Iteration History**:
- Iteration 1: [X] failures
- Iteration 2: [Y] failures
- ...
- Iteration [Final]: 0 failures (PASS)

**Total Fix Time**: [HH:MM:SS across all iterations]

**Action**: Exit recursive loop, proceed to [Next Phase]
**Communication**: Notify main agent of success
**Logging**: Log successful resolution and iteration count

Result: FAIL ❌

### Re-validation Failure (Iteration [Current] / 5)

**Specialist**: [Specialist Name]
**Iteration**: [Current] / [Max (5)]
**Status**: ❌ STILL FAILING

**Previous Failures**: [Count from previous iteration]
**Current Failures**: [Count from current iteration]
**New Failures**: [Count of new failures introduced]
**Persistent Failures**: [Count still failing]

**Analysis**:
- Failures resolved: [List]
- Failures persisting: [List]
- New failures introduced: [List]

**Decision**:
IF iteration < 5:
  ✅ Continue recursive loop
  ✅ Return to Step 2 (format new failure report)
  ✅ Increment iteration: [Current+1] / 5
ELSE (iteration >= 5):
  ⛔ Max iterations exceeded
  ⛔ Proceed to Step 8 (escalation)

Step 8: Escalate Unresolvable Issues

When max iterations (5) exceeded or timeout occurs:

Escalation Report:

## Escalation: Unresolvable Validation Issue

**Escalation ID**: ESC-{issue-number}-{specialist-name}-{timestamp}
**Generated**: [YYYY-MM-DD HH:MM:SS]
**Issue**: #{issue-number} - [Feature Name]
**Specialist**: [Specialist Name]
**Phase**: [Validation Phase]
**Escalation Reason**: [Max Iterations Exceeded / Timeout / Deadlock / Other]

---

### Escalation Summary

**Status**: ⛔ UNRESOLVABLE (Requires User Intervention)
**Total Iterations**: [Max (5)]
**Total Time**: [HH:MM:SS across all iterations]
**Persistent Failures**: [Count]

---

### Iteration History

| Iteration | Failures | Fixes Applied | Result |
|-----------|----------|---------------|--------|
| 1 | [Count] | [Summary] | FAIL |
| 2 | [Count] | [Summary] | FAIL |
| 3 | [Count] | [Summary] | FAIL |
| 4 | [Count] | [Summary] | FAIL |
| 5 | [Count] | [Summary] | FAIL |

**Pattern Analysis**: [Analysis of why failures persist across iterations]

### Persistent Failures

[List of failures that remain unresolved after 5 iterations]

#### Failure 1: [Test/Issue Name]
- **File**: [File path]
- **Line**: [Line number]
- **Error**: [Error message]
- **Iterations Failed**: [1, 2, 3, 4, 5]
- **Fixes Attempted**:
  - Iteration 1: [Fix attempted]
  - Iteration 2: [Fix attempted]
  - ...
- **Why Unresolved**: [Analysis of why this failure persists]

[... Additional persistent failures ...]

---

### Recommended Actions

**Option 1: User Manual Fix**
- User reviews failures and provides manual fix
- Validation orchestrator re-runs after user fix
- Risk: Requires user expertise

**Option 2: Skip Validation**
- Mark validation as "failed but proceeding"
- Document known issues
- Risk: Deploy with known failures

**Option 3: Abort Feature**
- Stop implementation
- Return feature to design phase
- Risk: Wasted effort on implementation

**Option 4: Extend Max Iterations**
- Allow additional iterations (e.g., 3 more)
- Continue recursive loop
- Risk: Potentially infinite loop

**Escalated To**: User / Main Orchestrator
**Awaiting Decision**: [Option 1 / Option 2 / Option 3 / Option 4]
**Validation Workflow**: PAUSED

Step 9: Log Communication History

Maintain complete audit trail:

Communication Log Entry:

### Communication Log

**Entry ID**: LOG-{issue-number}-{specialist-name}-{iteration}-{timestamp}

**Participants**:
- Validation Orchestrator (@validation-orchestrator)
- Specialist (@[specialist-name])
- Main Agent (@feature-implementer-main)

**Communication Flow**:

• Escalate when progress stalls
• Provide escape routes (skip validation, user intervention)

5. Comprehensive Logging

• Log all messages between agents
• Track status transitions
• Document fix attempts
• Maintain audit trail for troubleshooting

6. Graceful Escalation

• Provide context when escalating
• Offer multiple resolution options
