Decode a cryptic stack trace and pinpoint the failing call
Use when an error trace spans frameworks, async boundaries, or minified frames and the real cause is buried.
Act as a senior {{language}} debugger.
Here is a stack trace from {{environment}}:
{{stack_trace}}
Relevant code if it helps:
{{code_context}}
Walk me through it:
1. Translate the trace into plain English, frame by frame, top to bottom, marking which frames are my code vs library vs runtime.
2. Identify the single frame where the bug actually originates (not just where it surfaced).
3. State the exact precondition that triggered it (null/undefined, wrong type, race, exhausted resource, etc.).
4. Give the smallest code change that fixes the cause and explain why the symptom appeared far from the cause if it did.
Keep it terse and concrete. Cite frame numbers.Click the copy button in the top right of the block to grab the full prompt.
Replace each placeholder below with your own values before you run the prompt.
- {{language}}
- {{environment}}
- {{stack_trace}}
- {{code_context}}
