This skill needs Bun. The script uses bun:sqlite.

Trace the call chain from the given code location up to all entry points that can reach it.

Languages supported: any language indexed by CodeGraph (C#, Java, Kotlin, Go, TypeScript, JavaScript, Rust, C, C++, Vue, JSX, TSX, Terraform, Helm YAML, …)

Input: A symbol name, file path, or file:line reference. Examples:

• FindToolNameCollisions
• ToolsMappingExtensions.cs:145
• src/services/auth.ts:89
• CheckCertificate

Requirement: CodeGraph must be indexed in this project (.codegraph/ directory must exist). If it is missing, tell the user to run codegraph init first.

Steps

1. Run the script

The script is scripts/find-call-chain.ts in the base directory of this skill. Run it from the project folder, because it finds .codegraph/ from the current folder:

bun <skill-base-directory>/scripts/find-call-chain.ts "<input>"

Show the full output to the user verbatim.

2. Multiple symbol matches

If the script prints "Multiple symbols matched", list the candidates shown and ask the user to re-run with a file:line reference for the one they want.

3. No symbol found

If the script exits with "No symbol found":

• Try alternative spellings or a file:line reference
• Verify CodeGraph is up to date: codegraph index

Terminal node detection (built into the script — no LLM judgment)

The script stops walking a branch when:

Condition	Examples
kind = route (CodeGraph native)	Any framework's route node
Language name pattern match	*Controller (C#/Java), *Activity (Kotlin), main (Go/Rust/C), *Page/*Route (TS/JS)
No callers found	Leaf node in the call graph
Depth cap (6 hops)	Marked ⚠ depth cap in the tree
Cycle detected	Marked ⟳ cycle in the tree
