Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

analyze_pr_impactAnalyze PR Impact
Assess impact and risk from cached diff. Prerequisite: generate_diff. Auto-infer repo/language.
analyze_time_space_complexityAnalyze Time & Space Complexity
Analyze Big-O complexity. Prerequisite: generate_diff. Auto-infer language.
ask_about_codeAsk About Code
Answer questions about a cached file. Prerequisite: load_file. Auto-infer language.
detect_api_breaking_changesDetect API Breaking Changes
Detect breaking API changes. Prerequisite: generate_diff. Auto-infer language.
detect_code_smellsDetect Code Smells
Detect structural code smells in a cached file. Prerequisite: load_file. Auto-infer language.
generate_diffGenerate Diffread-only
Generate a diff of the current branch working changes and cache it for all review tools. You MUST call this tool before calling any other review tool. Use "unstaged" for working-tree changes not yet staged, or "staged" for changes already added with git add.

Generate test cases. Prerequisite: generate_diff. Auto-infer repo/language/framework.
load_fileLoad Fileread-only
Cache a single file for analysis tools (refactor_code, ask_about_code, verify_logic). Overwrites previous cache. Path is relative to server working directory (e.g. src/index.ts) or absolute (e.g. /home/user/project/src/index.ts).
refactor_codeRefactor Code
Analyze cached file for complexity, duplication, naming, and grouping improvements. Prerequisite: load_file. Set maxSuggestions to cap output (default 10).
verify_logicVerify Logic
Verify algorithms and logic in a cached file using Gemini code execution sandbox. Prerequisite: load_file. Auto-infer language.
