ast-grep-find

ast-grep-find is a skill for Claude Code from parcadei/Continuous-Claude-v3. It costs 17 tokens per session (706 once invoked), scanned A, original, MIT.

A guide for searching and refactoring code by understanding its syntax and structure, rather than matching plain text only. AST means abstract syntax tree, a representation of code elements and their relationships.

In plain words
What is it for?
Use it to find function calls, imports, and class definitions, or to rename and replace code patterns in Python, JavaScript, and TypeScript, with optional dry runs and directory limits.
Why use it?
It helps find code patterns while ignoring similar text in comments or strings, and makes replacements more precise across a codebase.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ast-grep-find scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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

Parameter Description
--pattern AST pattern to search (required)
--language Language: python, javascript, typescript, go, etc.
--path Directory to search (default: .)
--glob File glob pattern (e.g., **/*.py)
--replace Replacement pattern for refactoring
--dry-run Preview changes without applying
--context Lines of context (default: 2)

Pattern Syntax

Syntax Meaning
$NAME Match 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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
