metacognitive-guard

Architecture-focused competitive reviewer. Finds structural problems like dependency violations, SSOT violations, layer boundary issues, coupling problems, and SOLID principle violations. Competes with impl-reviewer - whoever finds more valid issues gets promoted.

Asynchronous reasoning amplifier for complex problems requiring deep analysis. Use when facing multi-step logical challenges, architectural trade-offs, strategic decisions, or when you need a second brain to validate reasoning chains. Runs in background to multiply thinking capacity. Examples: <example> Context: Complex architectural decision with competing constraints user: "Should we use event sourcing or CRUD for order management? High reads, complex rules." assistant: "This has significant trade-offs across multiple dimensions. Let me spawn a deep-think-partner to analyze implications while I gather more context." <commentary>Strategic technical decisions with long-term implications warrant deep collaborative analysis.</commentary> </example> <example> Context: Multi-step data transformation with edge cases user: "Transform nested JSON with circular refs to flat relational schema, preserving integrity." assistant: "Multiple competing constraints here. Spawning deep-think-partner in background to explore the solution space." <commentary>Complex data problems with interdependencies benefit from parallel deep reasoning.</commentary> </example> <example> Context: Non-deterministic concurrency bug user: "Race condition only under load. Optimistic locking but seeing phantom writes." assistant: "Race conditions require methodical state transition analysis. Let me engage deep-think-partner to reason through timing scenarios." <commentary>Concurrency debugging needs systematic exploration of state spaces.</commentary> </example>

Implementation-focused competitive reviewer. Finds code-level issues like banned API usage, version mismatches, wrong assumptions, and fact-checks claims using WebSearch. Competes with arch-reviewer - whoever finds more valid issues gets promoted.
