A clear bug report gives someone enough information to understand the problem and try to reproduce it. State what failed, provide numbered steps and exact inputs, separate expected from actual results, and include relevant software and environment details. If you are unsure whether it will happen again, say so.
What to include in a bug report
Use the receiving project’s issue form if it has one; fields vary by project. Otherwise, this compact template captures the details that usually make a report actionable without turning it into a questionnaire. It synthesizes guidance from Mozilla, Atlassian and MDN.
Copyable template
Summary: [Product or feature] [observable failure] when [important condition]
Environment: [app and version], [operating system/device], [browser/version if relevant]
Frequency: [every time / sometimes / once so far; conditions if known]
Steps to reproduce:
1. [Starting state or setup]
2. [Action and exact input]
3. [Next action]
Expected result: [What should happen]
Actual result: [What happened instead; exact error text if available]
Evidence: [Minimal test case, screenshot, log, or attachment, if useful and safe]
Notes: [Relevant condition or recent change; label uncertainty clearly]Omit fields that do not matter to the issue, and add any details the project’s form specifically requests.
Write a summary that identifies the failure
Make the title searchable and specific: name the affected feature, the observable failure, and a condition that distinguishes it when useful. “Checkout shows a blank page after applying a discount code” gives a maintainer more to work with than “Checkout is broken.” Describe what you saw; do not put an unverified cause in the title.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Make the reproduction steps repeatable
Number the steps in order and include the starting state, necessary setup, and actual inputs. Write them so someone unfamiliar with your actions can try them without guessing. If an account, sample file, setting, or prior action is needed, include that context—but do not share passwords, private data, or credentials.
For browser bugs, a small test case that isolates the behavior can help distinguish a product issue from other factors. MDN recommends a minimal test case and, where useful, checking whether the behavior differs across browsers. Include only comparisons you actually performed.

Separate expected behavior from what happened
State the expected result and actual result in separate fields. Include exact error text when available; distinguish an observed message or behavior from your interpretation of why it happened. Mozilla’s Bug Writing Guidelines call reproduction steps the most important part of a report and advise reporting one issue per report, with a clear summary and precise steps. See Mozilla’s guidelines.
Add relevant environment and frequency details
Software behavior can depend on the version, device, or platform. Include the details that could plausibly affect this particular issue rather than listing everything you know.

- Frequency: whether it happens every time, sometimes, or only once so far; note known conditions.
Atlassian’s bug-report template includes examples such as operating system, device, app or software version, browser version, connection type, frequency, and reproducibility. Its template is one structured example, not a universal requirement.
Choose evidence that helps, and share it safely
A screenshot, log, or minimal test case can clarify a failure that is difficult to describe. Attach evidence only when it adds useful context, and check it for private information such as names, account details, tokens, or messages before sharing. For browser bug reports, MDN’s guidance recommends relevant screenshots and a minimal test case where appropriate.

If a screenshot would make a web-page issue easier to understand, you can capture it yourself in a browser or use an API. ScreenshotNeo is a website screenshot API and MCP server; its clean-shot options remove supported consent banners, popups, and chat widgets before capture, which can be useful when those elements obscure the state being reported. It is not a substitute for describing the steps or expected behavior.

Common reporting mistakes
- Vague title: Replace “doesn’t work” with the feature and visible failure.
- Missing setup or input: Add the state and values needed to follow your steps.
- Expected and actual results blended together: Put them in separate fields so the discrepancy is clear.
- Diagnosis presented as fact: Label a suspected cause as a hypothesis, or leave it out.
- Unclear reproducibility: Say whether it happens every time, sometimes, or could not be repeated.
- Unhelpful or unsafe attachments: Share only evidence that clarifies the issue, and remove sensitive details first.
