agent-hub

Multi-agent collaboration plugin that spawns N parallel subagents competing on the same task via git worktree isolation. Agents work independently, results are evaluated by metric or LLM judge, and the best branch is merged. Use when: user wants multiple approaches tried in parallel — code optimization, content variation, research exploration, or any task that benefits from parallel competition. Requires: a git repo.

agent-workflow-designer

Design production-grade multi-agent orchestration systems. Covers five core patterns (sequential pipeline, parallel fan-out/fan-in, hierarchical delegation, event-driven, consensus), platform-specific implementations, handoff protocols, state management, error recovery, context window budgeting, and cost optimization.

Arena

"Arena orchestrates external engines — through competition or collaboration, the best outcome emerges."

Orchestrator not player · Right paradigm for task · Play to engine strengths · Data-driven decisions · Cost-aware quality · Specification clarity first

Trigger Guidance

Use Arena when the task needs:

multi-engine competitive development (COMPETE: compare approaches, select best)
collaborative multi-engine development (COLLABORATE: decompose, assign, integrate)
codex exec or Antigravity CLI orchestration for implementation
variant comparison with scored evaluation
self-competition with approach/model/prompt diversity
parallel execution via Agent Teams API

Route elsewhere when the task is primarily:

direct code implementation without engine orchestration: Builder
rapid prototyping without quality comparison: Forge
code review without engine execution: Judge
task decomposition planning only: Sherpa
security audit without implementation: Sentinel

Paradigms: COMPETE vs COLLABORATE

Condition	COMPETE	COLLABORATE
Purpose	Compare approaches → select best	Divide work → integrate all
Same spec to all	Yes	No (each gets a subtask)
Result	Pick winner, discard rest	Merge all into unified result
Best for	Quality comparison, uncertain approach	Complex features, multi-part tasks
Engine count	1+ (Self-Competition with 1)	2+

COMPETE when: multiple valid approaches, quality comparison, high uncertainty. COLLABORATE when: independent subtasks, engine strengths match parts, all results needed.

Execution Modes

Mode	COMPETE	COLLABORATE
Solo	Sequential variant comparison

Engines AVAILABLE	Recommended path
Codex + Claude + agy	Cross-Engine Competition with 3 engines (full diversity)
Codex + Claude (default baseline)	Cross-Engine Competition with 2 engines (codex variant + Claude subagent variant) OR Self-Competition with Codex (2-3 approach variants) — pick per task
Codex only	Self-Competition (approach hints / model variants / prompt verbosity)
0 engines	ABORT → notify user

Phase	Required action	Key rule	Read
`SPEC`	Validate specification completeness	Clear spec before any execution	`references/engine-cli-guide.md`
`SCOPE LOCK`	Lock allowed/forbidden files per variant/task	No engine writes outside scope	`references/engine-cli-guide.md`
`EXECUTE`	Run engines on isolated branches	Solo: sequential, Team: parallel+worktrees	`references/team-mode-guide.md`
`REVIEW`	Quality gate per variant (scope+test+build+review+criteria)	Every variant passes gate	`references/evaluation-framework.md`
`EVALUATE`	Score weighted criteria, optional refine	Evidence-based selection	`references/evaluation-framework.md`
`ADOPT`	Select winner with rationale	Document why	`references/evaluation-framework.md`
`VERIFY`	Verify build+tests+security	No regressions	`references/engine-cli-guide.md`

Recipe	Subcommand	Default?	When to Use	Read First
Compete Mode	`compete`	✓	Multi-variant comparison (selection)	`references/evaluation-framework.md`
Collaborate Mode	`collaborate`		Engine-divided integration	`references/collaborate-mode-guide.md`
Solo Mode	`solo`		Single-engine execution	`references/engine-cli-guide.md`
Quick Mode	`quick`		Lightweight comparison	`references/evaluation-framework.md`

Signal	Approach	Primary output	Read next
`compete`, `compare`, `variant`, `best approach`	COMPETE paradigm	Winning variant + evaluation report	`references/evaluation-framework.md`
`collaborate`, `decompose`, `multi-part`, `integrate`	COLLABORATE paradigm	Integrated implementation	`references/collaborate-mode-guide.md`
`quick`, `small change`, `≤3 files`	Quick mode	Lightweight comparison/integration	`references/evaluation-framework.md`
`team`, `parallel`, `3+ variants`	Team mode	Parallel execution report	`references/team-mode-guide.md`
`self-competition`, `single engine`	Self-Competition	Best variant from single engine	`references/engine-cli-guide.md`
`calibrate`, `learning`, `effectiveness`	CALIBRATE workflow	AES report + adaptation	`references/execution-learning.md`
unclear engine orchestration request	Auto-select paradigm + mode	Implementation + evaluation	`references/engine-cli-guide.md`

Trigger	Condition	Scope
AT-01	Session execution complete	Lightweight
AT-02	Same engine+task_type fails/low-score 3+ times	Full
AT-03	User overrides paradigm or engine selection	Full
AT-04	Quality feedback from Judge	Medium
AT-05	Lore execution pattern notification	Medium
AT-06	30+ days since last CALIBRATE review	Full

`references/question-templates.md`	You need INTERACTION_TRIGGERS question templates.
`references/execution-learning.md`	You need CALIBRATE workflow, AES scoring, learning triggers, Engine Proficiency Matrix, adaptation rules, or safety guardrails.
`references/multi-engine-anti-patterns.md`	You need multi-engine orchestration anti-patterns (MO-01–10), distributed system principles, failure mode matrix, or reliability patterns.
`references/ai-code-quality-assurance.md`	You need AI-generated code quality statistics (2025-2026), problem categories (QA-01–08), defense-in-depth model, or review strategy.
`references/engine-prompt-optimization.md`	You need GOLDE framework, engine-specific optimization, or prompt anti-patterns (PE-01–10).
`references/competitive-development-patterns.md`	You need cooperative patterns (CP-01–08), COMPETE/COLLABORATE design analysis, diversity strategy, or paradigm selection optimization.
`_common/OPUS_48_AUTHORING.md`	You are sizing the comparison report, deciding adaptive thinking depth at paradigm selection, or front-loading paradigm/engines/criteria at SPEC. Critical for Arena: P3, P5.
`_common/PROOF_CARRYING.md`	You are invoked in COMPETE mode from `nexus acceptance` Phase 2A as the Dual-Implementation Oracle for in-scope domains (money / authz / state-machine / inventory / regulated). AI-A on engine E1 + AI-B on engine E2 + AI-C (adversarial reviewer) on engine E3 with different LLM families per G4 diversity requirement. AI-A and AI-B receive spec in different forms (NL vs formal vs decision table). Triangulate against Source-of-Truth Spec (G10), not against each other only — "diff = 0" alone does NOT auto-pass.
