HLSL — 106 Operations for AI Agents

This page is the canonical reference an AI coding agent uses to refactor, query, and analyze HLSL code through the act MCP server. 106 operations available: 32 refactor, 18 query, 42 analysis, 14 verification. Each operation is callable from Claude Code, Cursor, Codex, OpenCode, or any MCP-compatible agent host. Click any operation for a stable anchor link suitable for citation.

Premium language. Operations on HLSL require an Elite license or above. See pricing.

Refactor

Operation	Description
`add-cbuffer-packing`	Add cbuffer packing configuration to structure for GPU memory alignment
`add-function-attribute`	Insert a function attribute (e.g., [numthreads(...)]) before a shader function
`add-null-guard`	Insert an early-return null guard for a pointer parameter
`add-register-binding`	Add register/slot binding for GPU resource allocation
`add-semantic`	Insert input/output semantic (e.g., :SV_POSITION)
`convert-dot-product`	Replace a manual dot-product expansion (a.x*b.x + ...) with dot(a, b)
`convert-for-to-while`	Transform for loop into equivalent while loop
`convert-ternary-to-if-else`	Replace ternary operator with if-else statement
`convert-to-const`	Mark mutable variable as const
`convert-to-static`	Mark variable as static for persistent state across invocations
`convert-to-ternary`	Replace if-else expression with ternary operator
`convert-to-vector`	Convert a scalar variable declaration to a vector type
`convert-while-to-for`	Transform while loop into equivalent for loop
`extract_function`	Extract a code selection into a new function — automatically infers parameters, return types, and inserts the call site. Use instead of manually cutting/pasting code. Works without LSP; LSP improves type inference. Params: file (string), new_name (string), start_line (u32), start_column (u32), end_line (u32), end_column (u32) [, preview (bool), receipt (bool)]
`extract_variable`	Extract an expression into a named variable — inserts the declaration and replaces the expression with the variable name. Works without LSP. Params: file (string), new_name (string), start_line (u32), start_column (u32), end_line (u32), end_column (u32) [, preview (bool)]
`generate-constant-buffer`	Generate a cbuffer declaration with typed fields
`generate-input-struct`	Generate an input struct with semantic annotations
`generate-output-struct`	Generate an output struct with semantic annotations
`generate-register-annotations`	Auto-annotate all unbound global resource declarations with register slots
`generate-shader-entry-point`	Create vertex/pixel/compute shader entry function template
`generate-test-shader`	Create minimal test vertex/pixel shader pair
`generate-texture-declarations`	Generate a Texture2D and SamplerState pair with register bindings
`inline`	Inline a variable, function, or method — replace every usage with its definition body, then remove the original. The inverse of extract. Works without LSP (single-file); LSP enables cross-file inlining. Params: file (string), symbol (string) [, line (u32), preview (bool), receipt (bool)]
`insert_body`	Replace a function's implementation body with new code. AST-validated — rejects if the result has parse errors, so you can't accidentally break syntax. Use instead of manual text editing for function rewrites. Params: file (string), symbol (string), code (string) [, commit (bool)]
`move-to-constant-buffer`	Extract variable into constant buffer for engine updates
`move_symbol`	Move a function, class, or type to a different file and automatically update all imports across the codebase. Use instead of manually cut/paste + fixing imports. Works without LSP (single-file); LSP enables cross-file import updates. Params: file (string), symbol (string), destination (string) [, preview (bool), receipt (bool)]
`organize-includes`	Sort and group #include directives
`recipe_run`	Run a codemod recipe: declarative match → transform → optional verify across modeled grammars. Preview lists matches; apply writes with optional E7 receipts and all-or-nothing rollback. Returns a per-site report.
`remove-dead-code`	Remove an unreachable branch from an if statement with a literal condition
`remove-unused-variable`	Remove a variable declaration that is declared but never used
`rename`	Rename a symbol and automatically update ALL references across the codebase. Safer and faster than find-and-replace — AST-aware, won't rename strings or comments. Works without LSP (single-file); LSP enables cross-file renames. Params: file (string), old_name (string), new_name (string) [, line (u32), column (u32), preview (bool), receipt (bool)]
`simplify-expression`	Simplify a mathematical expression by removing identity operations (+0, *1, etc.)
