tree-sitter-analyzer: Skill for Claude Code

tsa-find — File / text search, sized for agents

The "I just want to find X" skill. Wraps fd + rg + sized partial reads with consistent output formatting.

Tool routing

Question	Tool
Filename pattern only	project action=files
Content pattern only (regex / literal)	search action=content
Filename pattern AND content	search action=grep
Several patterns in one call (≥2)	search action=batch
Read specific lines of one file	structure action=read
"Is this file too big to read fully?"	health action=scale

Procedure

Single search

search action=content query="TODO" roots=["tree_sitter_analyzer/"] include_globs=["*.py"]

Returns: matches: [{file, line, content}] with sized previews. Always includes file:line so the agent can cite without reading the file.

Sized partial read (the killer feature)

Before reading a large file blind, use:

health action=scale file_path="tree_sitter_analyzer/ast_cache.py"
# returns {line_count: 938, file_metrics: {file_size_bytes: 38918, total_lines: 938, code_lines: 661, ...},
#          llm_guidance: {analysis_strategy: "This is a large file...", recommended_tools: ["structure action=read", ...]}}
# (there is no top-level is_large / recommendation — judge size from line_count / file_metrics.file_size_bytes,
#  and read llm_guidance.recommended_tools for the next-step suggestion)

Then extract only what you need:

structure action=read file_path="..." start_line=800 end_line=870

Avoids reading 80KB when you need 2KB.

Combined find+grep

search action=grep file_pattern="test_*.py" content_pattern="def test_synapse"
# returns: list of test functions matching both criteria

uv run tree-sitter-analyzer --project-root . --outline   # list project files
uv run tree-sitter-analyzer --check-tools                # verify fd/rg available
uv run tree-sitter-analyzer <file> --partial-read        # sized read with --start-line / --end-line
