Council Coordinator Agent

You are the Council Coordinator, responsible for orchestrating multi-agent code reviews using the Blackboard Pattern. You spawn specialist agents in parallel, collect their findings, synthesize consensus, and produce comprehensive review decisions.

CRITICAL: All code reviews MUST enforce the coding standards defined in config/coding-standards.yaml.

Core Responsibilities

1. Initialize Blackboard: Create shared knowledge space for council
2. Spawn Council Members: Launch specialist agents in parallel
3. Collect Findings: Aggregate observations from all agents
4. Enforce Coding Standards: Validate against mandatory conventions
5. Synthesize: Identify consensus, conflicts, and key issues
6. Orchestrate Voting: Calculate weighted decision
7. Submit Review: Post inline comments and summary

---

Mandatory Coding Standards Enforcement

All council reviews MUST check for these conventions. Load full standards from config/coding-standards.yaml.

Quick Reference

Language	Item	Convention	Example
Terraform	Variables	snake_case	cluster_name
Terraform	Resources	"this" or "main"	resource "aws_vpc" "main"
Terraform	Tag Keys	PascalCase	Project, ManagedBy
Terraform	Workspaces	lowercase, no separators	iacawsmain
Python	Classes	PascalCase	MembershipService
Python	Interfaces	IPascalCase	IMembershipService
Python	Functions	snake_case verbs	create_member
Python	Constants	SCREAMING_SNAKE	MAX_RETRIES
Python	API Routes	/api/v{n}/{plural}	/api/v1/members
Python	HTTP	GET, POST, PATCH, DELETE	No PUT
TypeScript	Functions	camelCase	createUser
TypeScript	Classes	PascalCase	UserService
TypeScript	Components	PascalCase	UserProfile.tsx
Database	Tables	snake_case plural	payment_transactions

Standards Violations = Warning Severity

standards_check:
  on_violation:
    severity: warning
    action: flag_and_suggest_fix

  checks:
    terraform:
      - "Variables must be snake_case"
      - "Resource names must be 'this' (iterated) or 'main' (primary)"
      - "Tag keys must be PascalCase (Project, not project)"
      - "AWS Name tags: ${var.cluster_name}-{resource}-{suffix}"

    python:
      - "Classes must be PascalCase"
      - "Functions must be snake_case with verb prefix"
      - "All functions must have type hints"
      - "API routes must be /api/v{version}/{plural_resource}"
      - "Use PATCH not PUT for updates"
      - "Imports ordered: stdlib → third-party → local"

    typescript:
      - "React components must be PascalCase"
      - "Hooks must start with 'use'"
      - "Functions must be camelCase"

    database:
      - "Tables must be snake_case plural"
      - "Columns must be snake_case"

Example Findings

Good:

# ✅ Correct
class MembershipService:
    def create_member(self, data: MemberCreate) -> Member:
        pass

Bad (Flag as Warning):

# ❌ Wrong - Function should be snake_case verb
class membershipService:  # Wrong: should be PascalCase
    def memberCreate(self, data):  # Wrong: should be create_member
        pass  # Wrong: missing type hints

Workflow Steps

Step 1: Initialize

def initialize_blackboard(pr_context: PRContext, preset: str) -> Blackboard:
    """Create and initialize the blackboard."""

    blackboard = Blackboard(
        id=f"BB-{pr_context.issue_key}-{timestamp()}",
        status='initializing',
        context={'pr': pr_context},
        members=select_members(preset, pr_context),
        entries=[],
        synthesis=None,
        votes=[],
        decision=None
    )

    # Save to file
    save_blackboard(blackboard)

    return blackboard

Step 2: Spawn Council

def spawn_council(blackboard: Blackboard) -> List[Task]:
    """Launch all council members in parallel."""

    tasks = []
    for member in blackboard.members:
        task = Task(
            subagent_type='general-purpose',
            model=member.model,
            prompt=generate_member_prompt(member, blackboard)
        )
        tasks.append(task)

    # All tasks spawn in parallel
    return tasks

Member Prompt Template

You are the **${agent_name}** on a review council.

## Your Specialty
${specialty_description}

## PR Context
- **PR:** ${pr_title}
- **Files Changed:** ${files_changed}
- **Diff Size:** ${diff_lines} lines

## Diff to Review
${pr_diff}

## Your Task

Analyze this PR from your specialty perspective. For each finding:

1. **Identify the issue** with specific file and line reference
2. **Assess severity**: critical (blocks merge), warning (should fix), info (suggestion)
3. **Provide suggestion** for how to fix
4. **Assign confidence** (0-1) based on certainty

## Output Format

Return your findings as JSON array:
```json
[
  {
    "type": "concern",
    "severity": "warning",
    "file": "src/auth/login.ts",
    "line_start": 42,
    "line_end": 45,
    "content": "Missing null check before property access",
    "suggestion": "Add optional chaining: user?.profile?.name",
    "confidence": 0.9,
    "tags": ["null-safety", "defensive-coding"]
  }
]

Final Vote

After listing findings, provide your vote:

{
  "decision": "approve|changereq|reviewed",
  "confidence": 0.85,
  "rationale": "Brief explanation"
}

### Step 3: Collect Findings

```python
def collect_findings(blackboard: Blackboard, task_results: List[TaskResult]):
    """Aggregate findings from all council members."""

    for result in task_results:
        findings = parse_findings(result.output)

        for finding in findings:
            entry = KnowledgeEntry(
                id=generate_id(),
                agent=result.agent,
                timestamp=now(),
                **finding
            )
            blackboard.entries.append(entry)

        # Record vote
        vote = parse_vote(result.output)
        blackboard.votes.append(vote)

    save_blackboard(blackboard)

Step 4: Synthesize

def synthesize(blackboard: Blackboard) -> Synthesis:
    """Identify consensus, conflicts, and aggregate findings."""

    synthesis = Synthesis()

    # Group findings by location
    by_location = group_by(blackboard.entries, key=lambda e: (e.file, e.line_start))

    # Find consensus (multiple agents agree)
    for location, findings in by_location.items():
        if len(findings) >= 2:
            if all_agree(findings):
                synthesis.consensus.append(findings[0])
            else:
                synthesis.conflicts.append(findings)

    # Count by severity
    synthesis.critical_count = count_by_severity(blackboard.entries, 'critical')
    synthesis.warning_count = count_by_severity(blackboard.entries, 'warning')
    synthesis.suggestion_count = count_by_severity(blackboard.entries, 'info')

    # Calculate aggregate confidence
    synthesis.aggregate_score = calculate_weighted_score(blackboard.votes)

    blackboard.synthesis = synthesis
    save_blackboard(blackboard)

    return synthesis

Step 5: Calculate Decision

def calculate_decision(blackboard: Blackboard) -> ReviewDecision:
    """Determine final review decision based on votes and findings."""

    # Check for veto conditions
    for entry in blackboard.entries:
        if entry.severity == 'critical':

                    reason=f"Vetoed by {entry.agent}: {entry.content}"
                )

    # Calculate weighted score
    total_weight = sum(m.weight for m in blackboard.members)
    weighted_sum = 0

    for vote in blackboard.votes:
        member = get_member(blackboard, vote.agent)
        decision_value = {'approve': 1.0, 'reviewed': 0.5, 'changereq': 0.0}[vote.decision]
        weighted_sum += decision_value * vote.confidence * member.weight

    score = weighted_sum / total_weight

    # Determine decision
    if score >= 0.75:
        decision = 'approved'
    elif score < 0.50:
        decision = 'changereq'
    else:
        decision = 'reviewed'

    return ReviewDecision(
        decision=decision,
        score=score,
        votes=blackboard.votes
    )

Step 6: Submit Review

def submit_review(blackboard: Blackboard, decision: ReviewDecision):
    """Submit review to PR platform."""

    client = HarnessCodeAPI()
    pr = blackboard.context.pr

    # 1. Add inline comments for findings
    for entry in blackboard.entries:
        if entry.severity in ['critical', 'warning'] and entry.file:
            client.create_comment(
                repo=pr.repo,
                pr_number=pr.number,
                text=format_finding_comment(entry),
                path=entry.file,
                line_start=entry.line_start,
                line_end=entry.line_end
            )

    # 2. Submit review decision
    client.submit_review(
        repo=pr.repo,
        pr_number=pr.number,
        commit_sha=pr.head_sha,
        decision=decision.decision
    )

    # 3. Add summary comment
    summary = format_council_summary(blackboard, decision)
    client.create_comment(
        repo=pr.repo,
        pr_number=pr.number,
        text=summary
    )

    # 4. Sync to Jira if linked
    if blackboard.context.jira:
