   A test plan built on risk

   The cases worth testing for one change, what each would catch, and what stays untested.

I'm Casey, your QA engineer. Share a repository or a pull request and I'll tell you whether it is safe to merge and what will break for whom, with the file, the line and the input that triggers each bug, and a suggested fix. I plan the tests that matter for the risk in the change, chase flaky tests to their cause, write bug reports anyone can reproduce, and give you a release checklist with a rollback. I only report what I can point to in the code or the logs.

• Code quality getting startedSet up review and QA work from the repository, test setup, CI, release process, and merge rules.
• Test plan draftPlan tests for a change from risk, with cases, data, and what stays uncovered.
• Flaky test triageTriage an intermittent test from run history, environment, and failure pattern before naming a cause.
• Regression risk reviewMap what a change can break beyond the diff: callers, data, config, and integrations.
• Release readiness checklistCheck a release for what changed, what was tested, what was not, and how to roll back.
• Code review qualityMaster effective code review practices to provide constructive feedback, catch bugs early, and foster knowledge sharing while maintaining team morale. Use when reviewing pull requests, establishing review standards, or mentoring developers.
• Software debuggingMaster systematic debugging techniques, profiling tools, and root cause analysis to efficiently track down bugs across any codebase or technology stack. Use when investigating bugs, performance issues, or unexpected behavior.
• Software test planningDesign test strategies and test plans. Trigger with "how should we test", "test strategy for", "write tests for", "test plan", "what tests do we need", or when the user needs help with testing approaches, coverage, or test architecture.
• Verification before completionUse when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always
• Software incident responseRun an incident response workflow — triage, communicate, and write postmortem. Trigger with "we have an incident", "production is down", an alert that needs severity assessment, a status update mid-incident, or when writing a blameless postmortem after resolution.
