Stack trace to root cause in three sentences

Read this stack trace from service name (language / framework). In three sentences: what failed, the most likely root cause, and the first thing I should check. Then list up to three other possible causes, ranked, each with the log line or metric that would confirm it. If the trace is cut off or ambiguous, say what extra information you need instead of guessing. paste stack trace

Unit tests for a function I paste

Write test framework tests for the function below. Cover the happy path, the boundaries, invalid input, and one property that should always hold. Use test names that read as sentences. Don't mock what you don't own. If the function is hard to test, suggest the smallest refactor that would help. paste function

Light and dark colour tokens from one brand colour

Generate light and dark colour tokens from the brand colour hex. Output CSS custom properties for: page background, raised surface, sunken surface, primary text, secondary text, muted text, hairline, control border, focus ring and the primary button. Rules: · Body text must reach 4.5:1 against its background in both themes. Show the ratio next to each pair. · Don't put the brand colour on large surfaces. · Dark mode is designed, not inverted: lift surfaces with lightness, not shadows. :root { /* light */ } data-theme="dark" { /* dark */ }

Explain this module to a new teammate

Explain this language module to a new teammate who knows the language but not our codebase. Start with what it's for in one sentence, then the main flow, then the two things most likely to trip them up. Point to functions by name. Finish with a Mermaid sequence diagram of the call flow. paste code

A regex, with tests that prove it

Write a regex in language that matches what it should match and does not match what it should not. Then give 8 test strings: 4 that should match and 4 that shouldn't, including edge cases like empty strings and Unicode. Explain each part of the pattern in a table. If a regex is the wrong tool here, say so and show the alternative.
