JBCT Parallel Code Review

Comprehensive JBCT compliance review using parallel focused workers with aggregation.

Usage

/jbct-review # Full codebase, all focus areas /jbct-review src/main/java # Specific path, all focus areas /jbct-review --focus="Composition,Null" # Specific focus areas only /jbct-review src --focus="ValueObjects,UseCases" # Combined path and focus

Arguments

• path (optional): Directory or file to review. Default: entire codebase

• --focus (optional): Comma-separated list of focus areas. Default: all 10 areas

Focus Areas

Short Name Full Focus Area

ValueObjects

Value Objects (factories + immutability)

UseCases

Use Cases (structure + composition)

ReturnTypes

Return Types (Result/Promise, Void→Unit, no exceptions)

Structural

Structural Patterns (Leaf, Sequencer, Fork-Join)

Composition

Composition Rules (fold() abuse, lambda complexity)

Null

Null Policy (Option usage)

ThreadSafety

Thread Safety (immutability, shared state)

Naming

Naming Conventions (factories, zones, acronyms)

Testing

Testing Patterns (assertions, organization)

CrossCutting

Cross-Cutting Concerns (security, performance, logging)

Execution Steps

Step 1: Parse Arguments

1. Extract path argument (if provided, default to current directory)
2. Extract --focus argument (if provided, default to all 10 areas)
3. Parse focus areas into list

Step 2: Discover Files

1. Use Glob to find all Java files in target path: **/*.java
2. Filter out test files if reviewing production code only
3. Count total files to review

Step 3: Launch Parallel Workers

For each focus area, launch a jbct-reviewer agent with the focus parameter:

Task tool call: subagent_type: "jbct-reviewer" prompt: | Review the following Java files for JBCT compliance.

**Focus Area:** [FOCUS_AREA_NAME]

Check ONLY for violations in this specific area. Ignore other issues.

Files to review:
[LIST_OF_FILES]

Report findings with severity levels (Critical/Warning/Suggestion/Nitpick).

Launch all workers in parallel using multiple Task tool calls in a single message.

Step 4: Collect Results

Wait for all workers to complete. Each returns structured findings.

Step 5: Aggregate Results

Launch a general-purpose agent to consolidate all reports (using jbct-reviewer for aggregation would exceed the 10-agent limit):

Task tool call: subagent_type: "general-purpose" prompt: | Aggregate the following JBCT review reports into a unified assessment.

**Individual Reports:**

--- ValueObjects Report ---
[REPORT_1]

--- UseCases Report ---
[REPORT_2]

... (all 10 reports)

Tasks:
1. Deduplicate findings (same file:line across reports)
2. Count issues by severity (Critical/Warning/Suggestion/Nitpick)
3. Determine overall compliance level and recommendation
4. Generate unified report following the format in Step 6

Step 6: Output Final Report

Present the aggregated report to the user:

JBCT Parallel Review Report

Path: [TARGET_PATH] Files Reviewed: [COUNT] Focus Areas: [LIST or "All 18"]

Example Execution

User: /jbct-review src/main/java

1. Parse: path = "src/main/java", focus = all 10 areas
2. Discover: 47 Java files found
3. Launch 10 parallel workers:
   • Worker 1: focus="Value Objects"
   • Worker 2: focus="Use Cases"
   • Worker 3: focus="Return Types"
   • Worker 4: focus="Structural Patterns"
   • Worker 5: focus="Composition Rules"
   • Worker 6: focus="Null Policy"
   • Worker 7: focus="Thread Safety"
   • Worker 8: focus="Naming Conventions"
   • Worker 9: focus="Testing Patterns"
   • Worker 10: focus="Cross-Cutting Concerns"
4. Wait for all workers to complete
5. Launch aggregator: focus="Aggregate" with all 10 reports
6. Output unified report: 3 Critical, 12 Warning, 8 Suggestion, 5 Nitpick

Notes

• Each worker reviews ALL files but only checks for violations in its focus area

• This ensures thoroughness: narrow focus = deeper analysis

• Parallel execution: all 10 workers run simultaneously

• Aggregator deduplicates and consolidates findings into unified report
