Capabilities

More than 400 tools, one idea behind all of them: the answer comes from the compiler's view of the solution, not from text. These are the families, and the questions each one answers.

Navigation and understanding

Symbols, references, callers, implementations, inheritance, type outlines, declaration source and project docs. The lookup that greps try to approximate — resolved through Roslyn, so overloads, generics, partial types and interface dispatch are answered exactly. find_symbol, read_symbol, find_references, find_callers, find_implementations, get_type_members, get_symbol_info, get_xml_docs.

Analysis

Whole-solution audit, compiler diagnostics and the mechanical ones fixed, inspections with code fixes, cyclomatic and cognitive complexity with the lines that own the score, static Big-O estimates, churn × complexity hotspots, dead code, structural duplicates, CWE-tagged security findings, async anti-patterns, allocation anti-patterns, dependency injection and namespace coupling. solution_audit, inspect_code, complexity_report, analyze_complexity, find_security_issues, find_dead_code, fix_complexity.

Refactoring

A full semantic refactoring catalogue — rename, extract method, extract class and superclass, change signature, move type and members, convert between kinds — most of it compiler-gated: an edit that would introduce an error is refused, and every write is recorded so it can be reverted. apply_rename, extract_method, change_signature, safe_delete, move_type, reduce_complexity.

Code style

simplify_code applies the IDE's mechanical quick fixes without an IDE: the rewrite engine behind the quick-fix popup, with a per-document compiler gate, option-driven rules that respect your .editorconfig, and a recorded, revertible edit history. Visual Basic has its own layer, simplify_vb_code. apply_code_fix executes the analyzers' own fixers; code_cleanup, format_code and optimize_usings complete the sweep.

Razor, Blazor and XAML

Razor pages and Blazor components are read from disk with a dedicated scanner: inventory and wiring, markup/accessibility/maintainability rules, and CWE-tagged security rules — with verified, history-recorded edits. XAML has its own layer: inventory with the project's dialect, markup diagnostics, binding paths checked against their data type, the element tree and navigation by name, key and style. razor_pages, analyze_razor_pages, find_razor_vulnerabilities, razor_edit, xaml_pages, xaml_bindings.

Runtime work

Build with structured diagnostics, run, test with coverage, debug through a real DAP debugger with breakpoints and watch windows, run benchmarks, and profile a live .NET process — CPU, GC, allocations, I/O, locks, dumps — with verdicts in plain language. build_project, run_tests, get_test_coverage_map, debug_launch, quick_benchmark, profile_slowdown.

The wider loop

The plumbing around the code: NuGet package facts, vulnerability checks and fixes, .NET modernization with a build gate that rolls back, EF Core migrations, Git and GitHub, Docker, repository scaffolding (licenses, CONTRIBUTING, CI workflows), a solution-scoped kanban board with memory, and run_plan to execute a whole dependency graph of tool calls in one round trip. update_solution, check_nuget_vulnerabilities, ef_migrations, git_conflicts, gh_pr, board_brief, run_plan.

Metacode

One canonical pseudocode model for C#, Visual Basic, Razor, JavaScript, Python, C++ and Rust — and for code recovered from binaries: .NET assemblies decompiled with ILSpy, native binaries recovered with Ghidra. The same algorithm prints the same body whichever frontend produced it, so two spellings of an algorithm can be compared line by line, and a decompiled library can be queried like source. metacode_translate, metacode_compare, decompile_to_metacode, analyze_native_binary.

The complete catalogue — every tool, grouped by area, with a one-line description — is the tool catalogue in the repository ; the guides in this area show the ways of working with each family.
