code-search
Structural code search using tree-sitter queries — find AST patterns like specific function calls, composite literals, or node shapes across the workspace or in a single file. More precise than regex. Use when grep is too imprecise for the pattern. Activated by runectl syntax search/query.

# Code Search
Tree-sitter structural search via `runectl syntax`.
## runectl syntax search
Search workspace using a tree-sitter query.
```
Usage:
runectl syntax search <query> [flags]
Flags:
-c, --capture stringArray Capture name filter (repeatable)
-F, --format string Output format: table, json, or Go template
-L, --lang stringArray Language filter (repeatable, e.g. go, python)
```
For simple "find all functions" queries, prefer `runectl syntax
searchnode` from the code-structure skill instead.
Example — find all struct type definitions in Go files:
```bash
$ runectl syntax search '(type_declaration (type_spec name: (type_identifier) @name type: (struct_type)))' -L go
file:///src/rune-agent/agent/agent.go Config 44:5-44:11 name
file:///src/rune-agent/agent/agent.go Agent 72:5-72:10 name
file:///src/rune-agent/dialogue/dialoguetui/cell_grid.go cellGrid 62:5-62:13 name
...
```
Each line shows `file text line:col-endLine:endCol capture_name`.
The `@name` capture matched the type identifier.
## runectl syntax query
Query a single file using a tree-sitter query.
```
Usage:
runectl syntax query <file> <query> [flags]
Flags:
-c, --capture stringArray Capture name filter (repeatable)
-F, --format string Output format: table, json, or Go template
```
Example — find all function calls in `bash.go`:
```bash
$ runectl syntax query agent/agentools/bash.go '(call_expression function: (selector_expression) @fn)'
file:///src/rune-agent/agent/agentools/bash.go json.Unmarshal 108:11-108:25 fn
file:///src/rune-agent/agent/agentools/bash.go fmt.Sprintf 117:35-117:46 fn
file:///src/rune-agent/agent/agentools/bash.go context.WithTimeout 133:16-133:35 fn
file:///src/rune-agent/agent/agentools/bash.go t.exec.Start 149:11-149:23 fn
...
```
## Tree-sitter query syntax
Queries are S-expressions matching syntax tree nodes. Each
pattern is parentheses containing the node type and optional
child matchers.
```bash
# All function declarations
'(function_declaration name: (identifier) @name)'
# Calls to a specific function
'(call_expression function: (identifier) @fn (#eq? @fn "Println"))'
# Composite literals of a specific type
'(composite_literal type: (type_identifier) @type (#eq? @type "Config"))'
# Binary expressions with two number literals
'(binary_expression (number_literal) (number_literal))'
```
