Review Local Changesneolabhq/context-engineering-kitReview your local uncommitted working-tree changes (git diff plus untracked files) and return actionable improvement suggestions. Use before committing, when nothing has been pushed yet.01Review PRneolabhq/context-engineering-kitReview an existing GitHub pull request and post inline review comments on its diff. Use when the changes are on an opened PR rather than your local working tree.01Root Cause Tracingneolabhq/context-engineering-kitUse when errors occur deep in execution and you need to trace back to find the original trigger - systematically traces bugs backward through call stack, adding instrumentation when needed, to identify source of invalid data or incorrect behavior01Setup Arxiv MCPneolabhq/context-engineering-kitGuide for setup arXiv paper search MCP server using Docker MCP01Setup Codemap CLIneolabhq/context-engineering-kitGuide for setup Codemap CLI for intelligent codebase visualization and navigation01Setup Context7 MCPneolabhq/context-engineering-kitGuide for setup Context7 MCP server to load documentation for specific technologies.01Setup Serena MCPneolabhq/context-engineering-kitGuide for setup Serena MCP server for semantic code retrieval and editing capabilities01Statusneolabhq/context-engineering-kitDisplay the current state of the FPF knowledge base01Subagent Driven Developmentneolabhq/context-engineering-kitUse when executing implementation plans with independent tasks in the current session or facing 3+ independent issues that can be investigated without shared state or dependencies - dispatches fresh subagent for each task with code review between tasks, enabling fast iteration with quality gates01Test Coverageneolabhq/context-engineering-kitUse after writing tests to assess coverage quality across structural, mutation, requirements, and API/integration dimensions; organized knowledge for choosing and interpreting coverage analyses.01Test Driven Developmentneolabhq/context-engineering-kitUse when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first01Test Promptneolabhq/context-engineering-kitUse when creating or editing any prompt (commands, hooks, skills, subagent instructions) to verify it produces desired behavior - applies RED-GREEN-REFACTOR cycle to prompt engineering using subagents for isolated testing01Test Skillneolabhq/context-engineering-kitUse when creating or editing skills, before deployment, to verify they work under pressure and resist rationalization - applies RED-GREEN-REFACTOR cycle to process documentation by running baseline without skill, writing to address failures, iterating to close loopholes01Thought Based Reasoningneolabhq/context-engineering-kitUse when tackling complex reasoning tasks requiring step-by-step logic, multi-step arithmetic, commonsense reasoning, symbolic manipulation, or problems where simple prompting fails - provides comprehensive guide to Chain-of-Thought and related prompting techniques (Zero-shot CoT, Self-Consistency, Tree of Thoughts, Least-to-Most, ReAct, PAL, Reflexion) with templates, decision matrices, and research-backed patterns01Tree Of Thoughtsneolabhq/context-engineering-kitExecute tasks through systematic exploration, pruning, and expansion using Tree of Thoughts methodology with meta-judge evaluation specifications and multi-agent evaluation01Update Docsneolabhq/context-engineering-kitUpdate and maintain project documentation for local code changes using multi-agent workflow with tech-writer agents. Covers docs/, READMEs, JSDoc, and API documentation.01Whyneolabhq/context-engineering-kitIterative Five Whys root cause analysis drilling from symptoms to fundamentals01Write Conciselyneolabhq/context-engineering-kitApply writing rules to any documentation that humans will read. Makes your writing clearer, stronger, and more professional.01Write Testsneolabhq/context-engineering-kitAdd missing test coverage for your local code changes by generating new test files (covers uncommitted and untracked changes, or the latest commit if everything is committed). Use when you want write tests for new logic or increase test coverage.01
