Wraps the native AST primitives from @singularity-forge/native/{edit,ast} as
LLM tools so agents can do tree-sitter-anchored code edits instead of
substring-based Edit or line-anchor hashline.
- replace-symbol.ts (+117): wraps replaceSymbol(file, symbolPath, newBody);
matches function/class/method declarations via tree-sitter, returns
matched=false sentinel when the symbol isn't located.
- insert-around-symbol.ts (+122): wraps insertAroundSymbol with position
enum BeforeDecl/AfterDecl/AtBodyStart/AtBodyEnd.
- ast-grep.ts (+152): wraps astGrep for pattern matching across files with
$VAR/$$$ARGS meta-variables; returns ranked matches with byte/line/column
+ captured meta-variable bindings.
Each tool:
- typebox schema matching the existing AgentTool pattern (edit.ts)
- notifyFileChanged() into the LSP layer on write ops
- resolveToCwd() for path normalization
- catches native errors + returns isError result with the
NativeUnavailableError message pointing operators to
`nix develop` + `node rust-engine/scripts/build.js --dev`
Wire-in:
- tools/index.ts: re-exports + imports + entries in `allTools` map and
createAllTools() factory.
- extension-manifest.json: ReplaceSymbol / InsertAroundSymbol / AstGrep
appended to provides.tools so SF extension agents see them.
Higher value than substring/line-anchor for code in tree-sitter-supported
languages (TS/JS/TSX/Python/Rust). Edit + hashline remain for non-code
files. PascalCase names per the Claude-Code-aligned convention from
sf-mp9w20y1-nld9hc.
