Deep Research

This skill provides a systematic approach to researching and analyzing the codebase and external dependencies. It is designed to be used before starting complex implementation tasks.

<critical_tools> You MUST strictly follow the rules defined in the project's command guides.

1. Local Code Discovery

   • REQUIRED SUB-SKILL: Use codebase_search for local code discovery.
   • MANDATORY: Use codebase_search for local code discovery.

2. Sourcebot (External Search)

   • Reference: .claude/commands/sourcebot.md
   • MANDATORY: Use Sourcebot (5-7 times) for EXTERNAL libraries/frameworks only.
   • NEVER use it for local code.
   • Workflow: list_repos -> Identify ID -> search_code with filterByRepoIds.

3. Pal MCP Toolkit (Architecture Analysis)

   • Reference: .claude/commands/pal.md (unified Pal skill)
   • MANDATORY: Use pal skill and appropriate Pal MCP tools before complex tasks.
   • Available Tools: mcp__zen__analyze, mcp__zen__debug, mcp__zen__planner, mcp__zen__refactor, mcp__zen__codereview, mcp__zen__tracer
   • Scope: Architecture, Quality, Performance, Security, Tech Debt.
   • CRITICAL ENFORCEMENT:
     • YOU MUST ALWAYS complete ALL THE STEPS when using any Pal MCP tool.
     • NEVER stop in the middle of the steps.
     • If you don't complete the steps until next_step_required: false, YOUR TASK WILL BE INVALIDATED.
     • NO EXCEPTIONS.
   • MODEL REQUIREMENT:
     • MANDATORY: Always use model: "anthropic/claude-opus-4.6" for ALL Pal MCP tool calls.
     • NEVER use any other model when calling Pal MCP tools.

4. Context7 & Perplexity (External Knowledge)

   • Reference: .claude/commands/perplexity.md
   • Context7: Use for 3rd party libraries NOT in Sourcebot. Resolve ID -> Get Docs.
   • Perplexity: Use for ANY broad research, latest docs, or debugging. </critical_tools>

<research_strategy> MANDATORY: You MUST use your tools for EVERY research task. NO EXCEPTIONS.

1. Understand the Request: Identify the specific task, goal, or question.
2. Internal Discovery:
   • REQUIRED SUB-SKILL: Use codebase_search for local code discovery.
   • Search for relevant local code concepts, patterns, and files using natural language.
   • Identify existing architectural patterns.
   • Use codebase_search to search specific areas.
3. External Research (Sourcebot):
   • If the task involves external libraries, search for their usage patterns and docs using Sourcebot.
4. External Knowledge (Context7 & Perplexity):
   • Use Context7 for libraries not in Sourcebot.
   • Use Perplexity for broad research or debugging.
5. Deep Analysis (Pal Analyze):
   • Run the zen_analyze tool to get a comprehensive view of the architecture, risks, and quality.
   • Complete the analysis loop.
6. Synthesize: Combine findings from all sources into the final report. </research_strategy>

<quality_standards>

• MANDATORY: Use tools extensively before answering.
• Conciseness: Keep summaries high-signal and low-noise.
• Authoritative: Prioritize findings from the codebase and official documentation (via Sourcebot/Context7).
• No Hallucinations: NEVER include information not found via tools.
• Direct Output: Do NOT create files. Return the report directly in the chat. </quality_standards>

<output_format> Return a SINGLE comprehensive message with the following structure:

Deep Analysis Report: [Topic]

1. Context Summary

[Concise summary of what was found in the local codebase, including key files and architectural patterns]

2. External Insights

[Relevant patterns, best practices, or documentation found for external libraries]

3. Deep Analysis Findings

[Insights on Architecture, Security, Performance, and Tech Debt derived from Pal Analyze]

4. Implementation Plan / Recommendations

[Concrete next steps, solution design, or answer to the user's request]

5. Relevant Files

[List of absolute paths to the most important files discovered during research] </output_format>
