name	graphyn
description	Use Graphyn for symbol impact analysis, dependency lookup, usages, aliases, and property-level access before modifying code.

Graphyn Skill

Use this skill when the task involves changing, deleting, renaming, moving, or understanding a code symbol.

Workflow

1. Ensure the graph exists with graphyn analyze . or the refresh_graph MCP tool.
2. For changes to a symbol, inspect blast radius.
3. For deletion or rename, inspect usages.
4. For moving or extracting code, inspect dependencies.
5. Mention high-risk findings before editing.

Commands

graphyn query blast-radius SymbolName
graphyn query usages SymbolName
graphyn query deps SymbolName

If symbols are missing because files are ignored or filtered out:

graphyn analyze . --no-gitignore
graphyn analyze . --include "src/**/*.ts"
graphyn analyze . --exclude "tests/**"

When MCP is available, prefer:

• get_blast_radius
• get_symbol_usages
• get_dependencies
• refresh_graph

refresh_graph can receive path, respect_gitignore, include, and exclude.

Reading Results

• Aliases are real usages, even if text search misses them.
• properties_accessed matters for DTO/model field changes.
• Use --file path/to/file.ts if a symbol name is ambiguous.
