40 of 40 tools

Documented tools (40)

From project documentation. A server handshake does not verify each tool’s description or behavior.

roslyn_apply_rename

Apply or reject a previewed rename

roslyn_apply_signature_change

Apply or reject a previewed signature change

roslyn_build_project

Smart build: Roslyn diagnostics first, MSBuild only if clean

roslyn_change_signature

Add parameters with non-breaking forwarding overload

roslyn_check_drift

Workspace health probe on three axes: source drift (files changed without the workspace noticing), reference health (projects that loaded with no metadata references), and pending reload (a change not yet applied — the only signal that can account for a brand-new file)

roslyn_check_syntax

Validate a C# snippet for syntax (and optionally semantic) errors without writing to disk

roslyn_clean_solution

Remove all build artifacts

roslyn_find_callers

All methods that call a named symbol (direct or via interface dispatch)

roslyn_find_implementations

All types implementing an interface or overriding a member

roslyn_find_overloads

All overloads for a method on a containing type, with full signatures

roslyn_find_references

Every reference to a symbol across the solution

roslyn_find_string_literal

Search C# string literals with glob or regex; returns raw and decoded values

roslyn_find_unused

Private/internal source symbols with zero direct static references

roslyn_get_call_graph

All methods invoked within a method body (IOperation tree walk)

roslyn_get_diagnostics

Compiler errors and warnings without building

roslyn_get_file_outline

File structure (types + member signatures, no bodies)

roslyn_get_line_count

Line count for one or more files

roslyn_get_member_body

Source of a single method/property/field -- the token saver

roslyn_get_project_info

Project metadata: TFM, packages, language version

roslyn_get_symbol_definition

Jump to where a symbol is declared

roslyn_get_symbol_documentation

XML doc comments for any symbol

roslyn_get_symbol_info

What a name at a location actually resolves to

All members of a type with full signatures and doc summaries

roslyn_get_usings

Using directives + implicit global usings

roslyn_insert_lines

roslyn_list_files

Glob-based file enumeration (fast, no content)

roslyn_list_types

All types in the project with namespace/kind filters

Semantic C# editing -- replaces syntax nodes, validates syntax

roslyn_replace_in_file

Text-level find-and-replace with regex (any file type)

roslyn_restore_packages
