code_error_context

code_error_context returns the code around a given file and line number. It is designed for use when a build or test failure reports a specific location — paste the file and line in, get the relevant code back without reading the whole file.

Usage

code_error_context(file="src/services/payment.ts", line=42)

Parameters

Parameter	Type	Default	Description
file	string	required	Path to the file containing the error
line	number	required	Line number reported in the error

Output

src/services/payment.ts — around line 42

  39:   const result = await stripe.charges.create({
  40:     amount: order.total,
  41:     currency: 'usd',
→ 42:     source: card.token,   // ← error here
  43:     idempotency_key: key,
  44:   });

When to use

• A compiler or runtime error reports a file and line number
• A test failure points to a specific assertion
• You want context around a log line without loading the entire file

Workflow with code_build

code_build()
→ error[E0308] at src/services/payment.ts:42

code_error_context(file="src/services/payment.ts", line=42)
→ Shows code around line 42

code_get(name="PaymentService.charge")
→ Full function if you need more context
