Tools
| Name | Description |
|---|---|
analyze | Performs comprehensive code analysis with systematic investigation and expert validation. Use for architecture, performance, maintainability, and pattern analysis. Guides through structured code review and strategic planning. |
apilookup | Use this tool automatically when you need current API/SDK documentation, latest version info, breaking changes, deprecations, migration guides, or official release notes. This tool searches authoritative sources (official docs, GitHub, package registries) to ensure up-to-date accuracy. |
challenge | Prevents reflexive agreement by forcing critical thinking and reasoned analysis when a statement is challenged. Trigger automatically when a user critically questions, disagrees or appears to push back on earlier answers, and use it manually to sanity-check contentious claims. |
chat | General chat and collaborative thinking partner for brainstorming, development discussion, getting second opinions, and exploring ideas. Use for ideas, validations, questions, and thoughtful explanations. |
clink | Link a request to an external AI CLI (Gemini CLI, Qwen CLI, etc.) through PAL MCP to reuse their capabilities inside existing workflows. |
codereview | Performs systematic, step-by-step code review with expert validation. Use for comprehensive analysis covering quality, security, performance, and architecture. Guides through structured investigation to ensure thoroughness. |
consensus | Builds multi-model consensus through systematic analysis and structured debate. Use for complex decisions, architectural choices, feature proposals, and technology evaluations. Consults multiple models with different stances to synthesize comprehensive recommendations. |
debug | Performs systematic debugging and root cause analysis for any type of issue. Use for complex bugs, mysterious errors, performance issues, race conditions, memory leaks, and integration problems. Guides through structured investigation with hypothesis testing and expert analysis. |
docgen | Generates comprehensive code documentation with systematic analysis of functions, classes, and complexity. Use for documentation generation, code analysis, complexity assessment, and API documentation. Analyzes code structure and patterns to create thorough documentation. |
listmodels | Shows which AI model providers are configured, available model names, their aliases and capabilities. |
planner | Breaks down complex tasks through interactive, sequential planning with revision and branching capabilities. Use for complex project planning, system design, migration strategies, and architectural decisions. Builds plans incrementally with deep reflection for complex scenarios. |
precommit | Validates git changes and repository state before committing with systematic analysis. Use for multi-repository validation, security review, change impact assessment, and completeness verification. Guides through structured investigation with expert analysis. |
refactor | Analyzes code for refactoring opportunities with systematic investigation. Use for code smell detection, decomposition planning, modernization, and maintainability improvements. Guides through structured analysis with expert validation. |
secaudit | Performs comprehensive security audit with systematic vulnerability assessment. Use for OWASP Top 10 analysis, compliance evaluation, threat modeling, and security architecture review. Guides through structured security investigation with expert validation. |
testgen | Creates comprehensive test suites with edge case coverage for specific functions, classes, or modules. Analyzes code paths, identifies failure modes, and generates framework-specific tests. Be specific about scope - target particular components rather than testing everything. |
thinkdeep | Performs multi-stage investigation and reasoning for complex problem analysis. Use for architecture decisions, complex bugs, performance challenges, and security analysis. Provides systematic hypothesis testing, evidence-based investigation, and expert validation. |
tracer | Performs systematic code tracing with modes for execution flow or dependency mapping. Use for method execution analysis, call chain tracing, dependency mapping, and architectural understanding. Supports precision mode (execution flow) and dependencies mode (structural relationships). |
version | Get server version, configuration details, and list of available tools. |
