Force unrelated concepts together to discover emergent properties - "What if we treated X like Y?". Can't find approach that fits your problem. Conventional solutions feel inadequate. Need innovative solution. Stuck thinking inside one domain. Want breakthrough, not incremental improvement.
Skill Claude CodeCodex
Flip core assumptions to reveal hidden constraints and alternative approaches - "what if the opposite were true?". Stuck on assumptions you can't question. Solution feels forced. "This is how it must be done" thinking. Want to challenge conventional wisdom. Need fresh perspective on problem.

Test at extremes (1000x bigger/smaller, instant/year-long) to expose fundamental truths hidden at normal scales. Unsure if approach will scale. Edge cases unclear. Want to validate architecture. "Will this work at production scale?" Need to find fundamental limits.

Find one insight that eliminates multiple components - "if this is true, we don't need X, Y, or Z". Code has many similar-looking implementations. Growing list of special cases. Same concept handled 5 different ways. Excessive configuration. Many if/else branches doing similar things. Complexity spiraling.

Black Swan Analysis provides a rigorous methodology for identifying high-impact, unpredictable events while building systems that thrive under volatility. You must use this framework when the human partner challenges you on your claims, or when the human partner asks you to create plans from vague instructions.

Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation.
Skill Claude CodeCodex
Use when completing tasks, implementing major features, or before merging to verify work meets requirements - dispatches bounded reviewer subagents with TASKPACKET and REVIEWSTATUS envelopes before proceeding.
Skill Claude CodeCodex
Post-completion factory improvement analysis. Guides the retrospective agent through artifact discovery, pattern analysis, suggestion generation, and presenting proposed changes for approval. Use when the retrospective agent starts its post-completion phase.
Skill Claude CodeCodex
Use when errors occur deep in execution and you need to trace back to find the original trigger - systematically traces bugs backward through call stack, adding instrumentation when needed, to identify source of invalid data or incorrect behavior.
