Executes diagnostic investigation tasks to test debugging hypotheses. Runs tests, traces execution, checks git history, and reports evidence. (converted from agent)

Systematic, hypothesis-driven debugging workflow with triage-based track routing. Use when asked to "fix this bug", "debug this", "why is this failing", "this is broken", "investigate this error", "track down this issue", or any debugging situation. Supports --deep flag to force full investigation.

Keep a Changelog format guidelines and entry writing best practices. Use when writing changelog entries, updating CHANGELOG.md, or following Keep a Changelog specification.

Reviews git history and updates CHANGELOG.md with entries for [Unreleased] section (converted from agent)

A shared reference for Claude Code's Agent Teams features. Load this skill when building skills or agents that create teams, spawn teammates, coordinate multi-agent workflows, or integrate with team hooks.

This skill is a shared reference for Claude Code's 6 Task Management tools. Load it when your skill or agent needs to create, manage, or coordinate tasks.

Designs implementation blueprints for features using exploration findings and architectural best practices (converted from agent)

Synthesizes exploration findings into unified analysis with deep investigation capabilities and completeness evaluation (converted from agent)

Transform SDD tasks into test-first TDD task pairs. Reads existing tasks from /create-tasks and generates paired test tasks with RED-GREEN dependencies. Use when user says "create tdd tasks", "add tdd pairs", "convert to tdd", or wants to apply test-first ordering to SDD tasks.

Reference for advanced data structure patterns used in competitive programming and technical interviews. Covers heaps, monotonic stacks, tries, segment trees, Fenwick trees, stack-based parsing, and ordered sets with Python templates, recognition signals, and edge case guidance.

Documentation management workflow for MkDocs sites and standalone markdown files -- initialize, generate, update docs, and create change summaries. Use when asked to "create docs", "write README", "update documentation", "generate docs site", "write CONTRIBUTING", "manage documentation", or "docs changelog".

Generate a structured markdown report documenting codebase changes from the current working session. The report captures files changed, commit history, and a human-readable summary suitable for team reviews, handoff documentation, or personal records.

Execute a structured 6-phase workflow for managing documentation. Supports two documentation formats (MkDocs sites and standalone markdown files) and three action types (generate, update, change summary).

Execute pending Claude Code Tasks in dependency order with wave-based concurrent execution and adaptive verification. Supports task group filtering and configurable parallelism. Use when user says "execute tasks", "run tasks", "start execution", "work on tasks", or wants to execute generated tasks autonomously.

Execute TDD task pairs autonomously with RED-GREEN-REFACTOR verification. Orchestrates wave-based execution with strategic parallelism, routing TDD tasks to tdd-executor agents and non-TDD tasks to standard task-executor. Use when user says "execute tdd tasks", "run tdd tasks", "start tdd execution", or wants to execute TDD-paired tasks from create-tdd-tasks.

Provides language-specific patterns for TypeScript, Python, and React including idioms, best practices, and common patterns. Use when implementing features in these languages.

Behavioral rules and lifecycle event handlers for the core-tools package. Defines automated behaviors that trigger at specific points in the agent workflow. (converted from hooks)

Reference patterns for mathematical and combinatorial problem-solving. Covers modular arithmetic, prime sieves, GCD/LCM, binomial coefficients, fast exponentiation, counting techniques, inclusion-exclusion, and game theory. Load this skill when a problem involves number theory, combinatorics, modular operations, or strategic game analysis.

Guides through creating a new OpenCode command with interactive interview, $VARIABLE configuration, and validation. Use when user says "create opencode command", "new opencode command", "build command for opencode", or wants to create an OpenCode command markdown file.

Guides through creating a new OpenCode-compatible skill with interactive interview, best-practice enforcement, and validation. Use when user says "create opencode skill", "new opencode skill", "build skill for opencode", or wants to create an OpenCode SKILL.md file.
