End-to-end copy number variant detection workflow from BAM files. Covers CNVkit analysis for exome/targeted sequencing with visualization and annotation. Use when detecting copy number alterations from sequencing data.

Visualize copy number profiles, segments, and compare across samples. Create publication-quality plots of CNV data from CNVkit, GATK, or other callers. Use when creating genome-wide CNV plots, sample heatmaps, or chromosome-level visualizations.

Coach product managers and produce a PM Coaching Pack (context-specific definition of “good PM”, evidence-based assessment, growth bets + development plan, coaching cadence + session toolkit, follow-up tracker). Use for coaching PMs, developing PMs, leveling expectations, and creating growth plans. Category: Leadership.

Analyze codebase for patterns, issues, and improvements. Enforces analysis standards while incorporating user-specific requirements.

Use when asked for an architecture blueprint or explicitly asked to run the code-architect subagent.

code-audit-vigil

Analyze and map code structure, data flow, and dependencies in legacy codebases. Use for understanding call stacks, dependency trees, side effects, risk profiles, and generating Mermaid diagrams. Ideal for legacy codebases with zero tests.

Detect and refactor code duplication with PMD CPD. TRIGGERS - code clones, DRY violations, duplicate code.

Multi-language code coverage analysis, reporting, and quality gate enforcement

Standardized, hypothesis-driven debug investigation workflow for unexpected behavior, regressions, incidents, flaky tests, or production issues. Use to plan instrumentation, reproduce with decisive signals, compare runs, and narrow root cause without assuming any vendor or infrastructure.

Use when explaining code, concepts, or system behavior to a specific audience level - provides a structured explanation workflow with depth control and validation steps.

Use when asked to trace existing codepaths or explicitly asked to run the code-explorer subagent.

Use when generating boilerplate code, __init__.py files, or test scaffolds. Provides scripts that generate consistent, convention-following code.

code-guru

Language-specific coding guidelines. Use when implementing code in Python or other supported languages.

Migrate legacy code to modern frameworks, languages, and patterns with automated refactoring and testing

Use the VSCode CLI to open files at specific line and column positions when explaining code, debugging, pointing to TODOs, or guiding users to specific locations in files. Automatically invoked when Claude needs to show users exactly where in a file to look.

Use when asked to simplify recently changed code without changing behavior or explicitly asked to run the code-simplifier subagent.

Enforce test-driven development (RED-GREEN-REFACTOR). Use when implementing features, fixing bugs, or changing behavior - write failing test first, then minimal code to pass.

QA engineer and test automation specialist with deep expertise in Flutter testing. Use for designing test strategies, writing unit/widget/integration tests, improving test coverage, and ensuring code reliability.

Transfer code between files with line-based precision. Use when users request copying code from one location to another, moving functions or classes between files, extracting code blocks, or inserting code at specific line numbers.

Validate code examples across the 4-Layer Teaching Method with intelligent strategy selection. Use when validating Python/Node/Rust code in book chapters. NOT for production deployment testing.

Analyze a GitHub codebase to create comprehensive architecture documentation including ASCII diagrams, component relationships, data flow, hosting infrastructure, and file structure assessment.

Expert in codebase archaeology and documentation retrieval. Use this when starting new project phases, refactoring large modules, or integrating new frameworks.

Deep codebase exploration using semantic search and relationship mapping. Use when you need to understand the current codebase.

Unified dead code detection, AST-based duplicate detection, and cleanup tool combining Legacy Tech Remover + Comprehensive Auditor + Architectural Cleanup with Knip, depcheck, TypeScript, Vue-specific analysis, file size/token limit detection, and AST-powered refactoring suggestions.

Analyze code for style violations, pattern compliance, and quality issues

Execute development tasks using OpenAI Codex CLI for code generation, refactoring, feature implementation, and bug fixes. Use when the user asks to create code, add features, refactor, fix bugs, or generate tests. Requires Codex CLI installed.

Create or edit Codex execpolicy .rules files (allow/prompt/forbid commands, define prefix_rule patterns, add match/not_match tests) and validate them with codex execpolicy check. Use when a user mentions Codex rules, execpolicy, command policies, allowlists/denylists, or controlling which commands Codex can run, and when scope (global vs project) must be clarified.

Invoke OpenAI Codex CLI with the correct configuration for autonomous code generation. Use when you need Codex to generate or regenerate code files, implement features, or execute multi-step coding tasks.

Use Codex CLI in full-auto mode to fix issues iteratively until tests pass. Autonomous debugging and test-fixing loop with sandbox safety.
