Use when inferences or evaluations need to be evidence-backed; when prior reasoning felt premature or conclusion-first; when analyzing a document, claim, decision, or argument; when quality control of a prior analysis is needed; or when a judgment must hold up under adversarial scrutiny.

One of 7 test cases the skill fixed. Same model, same prompt, with and without the skill.
During Stage 5 Verification of a software architecture assessment, testing revealed a critical counter-example that refutes the primary conclusion. What is the required procedural action when Verification fails?
| Checked | Without skill | With skill |
|---|---|---|
| Restarts the reasoning loop back to Stage 1 Observation with the new counter-evidence rather than editing the conclusion directly. | Missed | Passed |
The instructions your model reads when the skill loads.
No inference without evidence. No conclusion without verification.
Every analysis passes through a mandatory 5-stage reasoning loop. Every stage is processed as a distinct, demarcated unit of work. The loop repeats from Observation if Verification fails.
Violating the letter of the rules is violating the spirit of the rules. This principle binds at every stage. No stage may be skipped or waved off as "obvious."
