What this skill tells the agent

AST-Grep Find

Structural code search that understands syntax. Find patterns like function calls, imports, class definitions - not just text.

When to Use

  • Find code patterns (ignores strings/comments)
  • Search for function calls, class definitions, imports
  • Refactor code with AST precision
  • Rename variables/functions across codebase

Usage

Search for a pattern

uv run python -m runtime.harness scripts/ast_grep_find.py \
    --pattern "import asyncio" --language python

Search in specific directory

uv run python -m runtime.harness scripts/ast_grep_find.py \
    --pattern "async def \$FUNC(\$\$\$)" --language python --path "./src"

Refactor/replace pattern

uv run python -m runtime.harness scripts/ast_grep_find.py \
    --pattern "console.log(\$MSG)" --replace "logger.info(\$MSG)" \
    --language javascript

Dry run (preview changes)

uv run python -m runtime.harness scripts/ast_grep_find.py \
    --pattern "print(\$X)" --replace "logger.info(\$X)" \
    --language python --dry-run

Parameters

ParameterDescription
--patternAST pattern to search (required)
--languageLanguage: python, javascript, typescript, go, etc.
--pathDirectory to search (default: .)
--globFile glob pattern (e.g., **/*.py)
--replaceReplacement pattern for refactoring
--dry-runPreview changes without applying
--contextLines of context (default: 2)

Pattern Syntax

SyntaxMeaning
$NAMEMatch single node (variable, expression)
$$$Match multiple nodes (arguments, statements)
$_Match any single node (wildcard)

Examples

# Find all function definitions
uv run python -m runtime.harness scripts/ast_grep_find.py \
    --pattern "def \$FUNC(\$\$\$):" --language python

# Find console.log calls
uv run python -m runtime.harness scripts/ast_grep_find.py \
    --pattern "console.log(\$\$\$)" --language javascript

# Replace print with logging
uv run python -m runtime.harness scripts/ast_grep_find.py \
    --pattern "print(\$X)" --replace "logging.info(\$X)" \
    --language python --dry-run

vs morph/warpgrep

ToolBest For
ast-grepStructural patterns (understands code syntax)
warpgrepFast text/regex search (20x faster grep)

Use ast-grep when you need syntax-aware matching. Use warpgrep for raw speed.

MCP Server Required

Requires ast-grep server in mcp_config.json.
