Agent Designer - Multi-Agent System Architecture

Agent Workflow Designer

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.

API Design Reviewer

GitHub Actions workflow design and hardening. Use when: creating CI/CD pipelines, securing workflows, optimizing build times, adding tests to pipelines, fixing workflow failures, working with .github/workflows/.

Codebase Onboarding

PostgreSQL and pgvector schema design. Use when: designing database schemas, adding vector embeddings, optimizing queries, creating indexes, planning migrations, working with schema.sql or schema_v2.sql.

Dependency and license review for Python projects. Use when: auditing requirements.txt, checking for vulnerabilities, reviewing licenses, updating dependencies, managing version constraints.

Docker and container development agent skill and plugin for Dockerfile optimization, docker-compose orchestration, multi-stage builds, and container security hardening. Use when: user wants to optimize a Dockerfile, create or improve docker-compose configurations, implement multi-stage builds, audit container security, reduce image size, or follow container best practices. Covers build performance, layer caching, secret management, and production-ready container patterns.

Conduct systematic literature reviews for research. Use when: writing grant background sections, synthesizing research findings, performing systematic reviews, identifying research gaps, building evidence for proposals, creating annotated bibliographies.

Generate comprehensive market research and analysis reports. Use when: analyzing grant funding landscapes, market sizing exercises, competitive analysis of funding sources, strategic planning for grant applications, creating investment or business case documentation.

MCP Server Builder

Migration Architect

Observability Designer (POWERFUL)

Browser automation and scraping with Playwright. Use when: building scrapers, debugging web automation, handling dynamic content, managing browser sessions, implementing retry logic for flaky scrapes, capturing screenshots.

Structured pull request review for code quality. Use when: reviewing PRs for ingestion code, schema changes, database migrations, Python code review, providing actionable feedback on pull requests.

RAG Architect - POWERFUL

Write competitive research proposals for NSF, NIH, DOE, DARPA, and foundations. Use when: writing grant proposals, preparing specific aims, developing broader impacts statements, creating budget justifications, responding to FOAs, structuring project narratives.

Runbook Generator

Security audit for external code and skill content. Use when: reviewing external skill files, checking code snippets from untrusted sources, validating MCP tool configurations, accepting contributions from external repos.

Scan codebases for technical debt, score severity, track trends, and generate prioritized remediation plans. Use when users mention tech debt, code quality, refactoring priority, debt scoring, cleanup sprints, or code health assessment. Also use for legacy code modernization planning and maintenance cost estimation.
