description	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

Script hooks

• bash .agents/scripts/pm/validate.sh
• bash .agents/scripts/pm/status.sh
