Find all @deprecated APIs in the workspace, count their callers, and extract migration guidance. Produces a prioritized report sorted by call count so you know which deprecations to tackle first.
Find unused exports, dead functions, and unreachable code across the workspace using LSP analysis. Cross-verifies detectUnusedCode with findReferences to eliminate false positives. Use to clean up technical debt or before a major refactor.
Diagnose and fix TypeScript/language type errors using LSP diagnostics, hover, and code actions. For each type error, fetches the expected vs actual types, surfaces quickfix suggestions, and optionally applies them. Use when getDiagnostics shows type errors you want to resolve quickly.
Test coverage heatmap from lcov or JSON coverage data. Finds coverage reports, parses line coverage per file, and renders a color-coded file-tree heatmap as HTML. Opens in the system browser.
Full debug workflow using IDE bridge tools. Runs tests to find failures, sets conditional breakpoints, evaluates expressions in the debugger, identifies root causes, applies fixes, and verifies. Use when debugging test failures or runtime issues.
Dependency graph for a file or symbol. Calls getCallHierarchy and findReferences, builds a directed graph, and renders an interactive HTML force-directed graph. Opens in the system browser.
Diagnostic dashboard across the workspace. Calls getDiagnostics, groups results by severity and file, and renders a sortable color-coded HTML table. Opens in the system browser.
Deep codebase exploration using IDE bridge LSP tools. Maps architecture, traces call chains, discovers entry points, and builds a mental model of unfamiliar code. Use when onboarding to a new codebase or understanding a module.
