v6.0.0 - Plugin System, /review Skill & Decision Engine Overhaul
Plugin System & Code Review Swarm
Highlights
This release transforms Claude Agent System into a proper Claude Code plugin with 4 skills, adds a dedicated code review command, and overhauls the decision engine.
New: Plugin Architecture
The system is now installable as a Claude Code plugin at claude-agent-system-plugin/:
/plugin marketplace add Kasempiternal/Claude-Agent-System
/plugin install pccAll skills (/systemcc, /pcc, /pcc-opus, /review) are now plugin skills with proper YAML frontmatter, argument hints, and model selection.
New: /review - Code Review Swarm
A review-only skill that deploys 6 parallel Anthropic review agents without modifying code:
/review # Review all uncommitted changes
/review staged # Review only staged changes
/review src/auth.ts # Review specific files| Agent | Focus |
|---|---|
| Bug & Logic Reviewer | Security, crashes, logic errors |
| Project Guidelines Reviewer | Style, CLAUDE.md standards |
| Silent Failure Hunter | Swallowed exceptions, bad fallbacks |
| Comment Analyzer | Stale docs, misleading comments |
| Type Design Analyzer | Encapsulation, invariants |
| Test Coverage Analyzer | Test gaps, edge cases |
Features:
- Health score (0-10) with deterministic severity-weighted formula
- Cross-agent correlation groups related findings
- Deduplicated consolidated report (orchestrator merges overlap)
- Agent verdicts table for quick scanning
- Opt-in simplification phase (2 parallel agents, only with user consent)
New: /pcc and /pcc-opus Skills
Parallel Claude Coordinator skills for implementation:
/pcc- Sonnet scouts (fast, cost-efficient) + Opus implementers/pcc-opus- Opus scouts + Opus implementers (maximum quality)
Both feature:
- Dynamic agent count (2-6 based on complexity)
- Phase 3.5: Clarification & Questions before plan creation
- Editable plan files at
.claude/plans/{task}.md - Parallel implementation with focused file ownership
- Code simplification phase
Enhanced: Decision Engine
The /systemcc decision engine was overhauled:
- Two-phase workflow selection with confidence scoring
- 3-dimensional analysis (complexity, risk, scope) - simplified from 8-dimensional
- Accurate parallel execution documentation
- Fixed 5 critical issues around honesty and accuracy
- Cleaned up phantom commands and aligned documentation
Documentation
- Root README fully updated with
/review,/pcc,/pcc-opussections - Plugin README rewritten with flow diagrams for all 4 skills
- Updated skill comparison tables and "When to Use" guide
- Plugin version bumped to 2.0.0
