Search Tool Hierarchy

When searching code, use this decision tree:

Decision Tree

Need CONCEPTUAL/SEMANTIC search?
  (how does X work, find patterns, understand architecture)
  → Use LEANN (/leann-search) - embedding-based semantic search
  → PreToolUse hook auto-redirects semantic Grep queries

Need to understand code STRUCTURE?
  (find function calls, class usages, refactor patterns)
  → Use AST-grep (/ast-grep-find)

Need to find TEXT in code?
  → Use Morph (/morph-search) - 20x faster
  → If no Morph API key: fall back to Grep tool

Simple one-off search?
  → Use built-in Grep tool directly

Tool Comparison

| Tool | Best For | Requires |

|------|----------|----------|

| LEANN | Semantic search: "how does caching work", "error handling patterns", conceptual queries | Index built |

| AST-grep | Structural patterns: "find all calls to foo()", refactoring, find usages by type | MCP server |

| Morph | Fast text search: "find files mentioning error", grep across codebase | API key |

| Grep | Literal patterns, class/function names, regex | Nothing (built-in) |

Examples

LEANN (semantic/conceptual):

"how does authentication work"
"find error handling patterns"
"where is rate limiting implemented"

AST-grep (structural):

"Find all functions that return a Promise"
"Find all React components using useState"
"Refactor all imports of X to Y"

Morph (text search):

"Find all files mentioning 'authentication'"
"Search for TODO comments"

Grep (literal):

class ProviderAdapter
def __init__
Regex patterns

LEANN Commands

# Search with semantic query
leann search opc-dev "how does blackboard communication work" --top-k 5

# List available indexes
leann list

# Rebuild index (when code changes)
leann build opc-dev --docs dir1 dir2 --no-recompute --no-compact --force

Excalidraw Diagram Generator

by github

vendor ×3

Generate Excalidraw diagrams from natural language descriptions. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", or "generate an Excalidraw file". Supports flowcharts, relationship diagrams, mind maps, and system architecture diagrams. Outputs .excalidraw JSON files that can be opened directly in Excalidraw.

Build and distribute Expo development clients locally or via TestFlight

Use when you have a written implementation plan to execute in a separate session with review checkpoints

Data structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.
