Comprehensive Rust code review for ownership, lifetimes, error handling, unsafe usage, and idiomatic patterns. Invokes the rust-reviewer agent.

Use this agent when you need an idea pressure-tested with brutal honesty, competitor teardown, market validation, and clear go/no-go guidance before building.

Review a massive PR file-by-file, looking for problems in each changed file

Expert startup business analyst specializing in market sizing, financial modeling, competitive analysis, and strategic planning for early-stage companies. Use PROACTIVELY when the user asks about market opportunity, TAM/SAM/SOM, financial projections, unit economics, competitive landscape, team planning, startup metrics, or business strategy for pre-seed through Series A startups.

Use this agent when you need to conduct authorized security penetration tests to identify real vulnerabilities through active exploitation and validation. Use penetration-tester for offensive security testing, vulnerability exploitation, and hands-on risk demonstration.

Expert Next.js 16 developer specializing in App Router, Server Components, Cache Components, Turbopack, and modern React patterns with TypeScript

Evaluation gatekeeper for fine-tuning — builds golden sets and graders, calibrates judges, baselines base models, and issues checkpoint promotion verdicts. Use when constructing an eval harness before training or gating a trained checkpoint. Deliberately independent from training execution.

Expert performance engineer specializing in modern observability, application optimization, and scalable system performance. Masters OpenTelemetry, distributed tracing, load testing, multi-tier caching, Core Web Vitals, and performance monitoring. Handles end-to-end optimization, real user monitoring, and scalability patterns. Use PROACTIVELY for performance optimization, observability, or scalability challenges.

Agent definition issue-tracker

Use this agent when you need expert analysis of type design in your codebase. Specifically use it (1) when introducing a new type to ensure it follows best practices for encapsulation and invariant expression, (2) during pull request creation to review all types being added, and (3) when refactoring existing types to improve their design quality. The agent will provide both qualitative feedback and quantitative ratings on encapsulation, invariant expression, usefulness, and enforcement

Holistic software architecture planner that evaluates tech stacks, designs scalability roadmaps, performs cloud-agnostic cost analysis, reviews existing codebases, and delivers interactive Mermaid diagrams with HTML preview and draw.io export

Run the ECC formatter quality gate for a single file and report remediation steps.

Build React components, implement responsive layouts, and handle client-side state management. Masters React 19, Next.js 15, and modern frontend architecture. Optimizes performance and ensures accessibility. Use PROACTIVELY when creating UI components or fixing frontend issues.

GitHub Copilot agent elasticsearch-observability

Team orchestrator that decomposes work into parallel tasks with file ownership boundaries, manages team lifecycle, and synthesizes results. Use when coordinating multi-agent teams, decomposing complex tasks, or managing parallel workstreams.

Google Antigravity subagent plugin-validator (antigravity-plugin-dev)

Improves the accessibility of markdown files using five GitHub best practices

Senior embedded software engineer specializing in firmware and driver development for ARM Cortex-M microcontrollers (Teensy, STM32, nRF52, SAMD). Decades of experience writing reliable, optimized, and maintainable embedded code with deep expertise in memory barriers, DMA/cache coherency, interrupt-driven I/O, and peripheral drivers.

Interactive verification agent for AI-generated output. Runs a three-layer pipeline (self-audit, source verification, adversarial review) and produces structured reports with source links for human review.

Expert performance engineer specializing in modern observability, application optimization, and scalable system performance. Masters OpenTelemetry, distributed tracing, load testing, multi-tier caching, Core Web Vitals, and performance monitoring. Handles end-to-end optimization, real user monitoring, and scalability patterns. Use PROACTIVELY for performance optimization, observability, or scalability challenges.

Architect agent. Reads orchestrator-output.md, AGENTS.md, and project-doc.md to produce a numbered step-by-step implementation plan. Pauses for human approval before implementation begins.

Use when optimizing existing React applications for performance, implementing advanced React 18+ features, or solving complex state management and architectural challenges within React codebases.

view_file-only code explorer that the plugin's other agents dispatch to map a codebase — locate files, trace how a flow is wired, find every caller of a symbol, answer "where does X happen".

Extract reusable patterns from the current session and save them as candidate skills or guidance. Use to review a session on demand and persist an approved skill file; continuous-learning-v2 is a separate, configurable Stop/PreToolUse/PostToolUse hook-observation and instinct-evolution system (background observer disabled by default) and is not an automatic equivalent of this command.
