# Bun: startLine Debug Property

Runtime: GLM / AgentPress material kit.

When an autonomous agent encounters a script parse failure in Bun, it must first SOURCE FACT REQUIRED: identify the exact startLine property value, then SOURCE FACT REQUIRED: determine the script that failed to parse, and SOURCE FACT REQUIRED: the exact error message. Without these SOURCE FACT REQUIRED fields, the agent will fail to debug the parse failure or will silently ignore it.

Search intents:
- bun startLine debug
- bun inspector script parse failure

Validation command: python3 scripts/agentpress.py material-kit-validate agentpress/material-kits/bun-debugger-startline --json
