Run a time-boxed Prototype Probe to retire material uncertainty before spec approval. Use when `spec.md` is still draft, `probe_required` is true, or a narrow experiment is needed to bound technical or delivery risk before planning.
prototype-skill
Trigger context
spec.md is still draft and contains material uncertainty
probe_required: true
approval would otherwise be speculative
a narrow experiment can retire a specific technical, UX, integration, or delivery risk faster than discussion alone
Required inputs
spec.md with uncertainty and probe fields populated
target uncertainty to retire or bound
time-box and experiment constraints
success or failure evidence expected from the probe
Output schema
updated draft spec.md
probe findings summary
explicit approval recommendation (approve, revise, or run another narrow probe)
touched surfaces and footguns list
Quality checks
probe stays time-boxed, normally <= 1 day
experiment is narrow and directly tied to the uncertainty being tested
no production merge happens directly from probe output
findings are folded back into spec.md before continuation
touched surfaces, footguns, and remaining uncertainty are explicit
Failure behavior
stop if the probe is too broad, open-ended, or not tied to a material uncertainty
return a narrower probe design when the current one is not safe or useful
do not present exploratory output as production-ready implementation
Allowed side effects
update draft spec.md
create or update temporary probe notes inside the project folder when needed
record approval recommendation and follow-up actions
