Explain Code

Explain Code

Explains code using semantic search and project knowledge for comprehensive context.

Inputs

Workflow

1. Check Known Issues

• check_known_issues(tool_name="code_search", error_text="")

2. Detect Project

• Infer from cwd if not provided; default automation-analytics-backend

3. Read File Content

• Read file from project path
• If lines provided: parse range (e.g., "10-50") and extract those lines
• Build file_content: path, content, start_line, end_line, exists

4. Search Related Code

• code_search(query=file_content.content[:200], project=project, limit=5)
• Parse results, exclude the file itself

5. Get Architecture Context

• knowledge_query(project=project, section="architecture.key_modules")
• Match file path to module purpose

6. Get Gotchas & Patterns

• knowledge_query(project=project, section="gotchas") — filter by file path keywords
• knowledge_query(project=project, section="patterns.coding")

7. Build Explanation

Output markdown with:

• Architecture Context: module and purpose
• Code: selected lines (with line numbers)
• Related Code: similar implementations
• Gotchas: relevant gotchas
• Coding Patterns: patterns to follow
• Next step: find_similar_code for more

8. Error Handling

• If "index not found": learn_tool_fix("code_search", "index not found", "Vector index not created", "Run skill_run('bootstrap_knowledge')")

9. Log

• memory_session_log("Explained code in {file}", "Project: {project}, Lines: {lines}")

Key MCP Tools

• code_search — find related code
• knowledge_query — architecture, gotchas, patterns
• check_known_issues, learn_tool_fix — error handling
• memory_session_log — session logging
