Cross-Domain Mechanism Transfer

Own structural-isomorphism mapping, mechanism translation, transfer boundaries, and a reversible experiment. Do not own open-ended metaphor writing or the truth of external cases.

Route

Use when the bottom contradiction and failure of ordinary local fixes are already clear, local candidates are exhausted or too similar, or the user asks to borrow mechanisms from distant fields and test them.

Skip undefined problems, decorative analogies, direct mature solutions with adequate evidence, and requests that require inventing historical examples. Use $socratic-problem-framing or $first-principles-rebuild first when the structure is not stable.

Procedure

1. Remove domain jargon and write the problem as a structure: actors, scarce resource, signal, incentive, bottleneck, feedback, or failure isolation.
2. Define similarity axes before searching: variables that must match and surface details that may differ.
3. Find cases from at least three meaningfully distant domains when breadth is requested; verify material facts rather than relying on folklore.
4. For each case record the original problem, mechanism, structural mapping, transferable part, boundary, and failure condition.
5. Select up to three mechanisms by structural match, transfer cost, reversibility, and risk—not by how memorable the analogy is.
6. Translate the best mechanism into concrete actions, resources, expected signals, and side effects.
7. Propose one low-cost reversible experiment with success metric, disconfirming signal, and exit condition.

Handoffs and Boundaries

• $fact-claim-audit verifies external examples.
• $bounded-explore-select may constrain search budget but does not own structural mapping.
• $think-one-step-further remains a lightweight reuse check; this skill owns deliberate distant-domain mechanism search and experiment design.

Completion Gate

Each analogy is justified by mechanism rather than surface resemblance, transfer limits are explicit, and the experiment can falsify a key assumption without committing the full system.
