Verify understanding

One goal, nothing more, nothing less: verify the engineer is ready to move to the implementation phase. Exercise their understanding of a feature before they work on it — the pipeline's other artifacts serve fresh agent sessions; this step serves the human. Active recall: the user produces the feature in their own words, you only steer and fix. Re-runnable: right after the ticket review, or days later just before implementation — every run starts fresh from the review file, no state kept between runs.

Input

A .TICKET-REVIEW.md. Read it and the ticket files and parent it links. A reference that exists only as a tracker URL (no local file) may be read from the tracker at conversation time. A ticket with a newer -vN fetch beside the one the review read has likely overtaken it: say so, read the newest ticket files, and treat the review's open questions as possibly answered there. Then look for a .TICKET-REVIEW.md under the newest ticket file's base, flat beside it or inside its -vN/ directory: one that exists and is not the input → say so and run the conversation from it, the given review at most context; none → the overtaken handling stands. The .REQUIREMENTS.md of the newest ticket file's base (none: the ticket's latest across -vN versions) is read for its Overrides, which win over the ticket text. Given a ticket file and no review, never improvise one: say a review is needed and stop, handing off /review-ticket <ticket-file> as a launch command named review-<slug> (format at the close) when review-ticket is available.

The conversation

A conversation, not a test — the last sync between a dev and their PO before development starts. Word your probes and corrections via explain-in-simple-language when available.

1. Ask the user to explain the feature in their own words: who uses it, what they see and do, why the feature exists, and what each ticket contributes.
2. Let them produce the narrative. Probe one weak spot at a time; correct and complete only from the review file and the referenced materials — flag what those don't settle, never improvise requirements.
3. Stay at that PO–dev depth: journey, actors, purpose, per-ticket contribution — not DTO, field, or architecture detail.

When the product's user-facing language differs from the conversation's, name each page, text, or element with its user-facing term in parentheses — "the client area (klantportaal)".

Done when the user has correctly produced — corrections absorbed — the journey, why the feature exists, and every input ticket's contribution: enough to start implementing. Close with a short wrap-up naming anything that stayed shaky, then, only when refine-ticket is available, hand off refining each ticket, in the set's suggested execution order, as its own fenced block under a label naming the ticket, holding one copy-pasteable launch command in the syntax of the agent tool in use (claude is only the example): claude --name refine-<slug> "/refine-ticket <ticket-file>"; then the alternative: one line offering the tool's clear command (/clear is only the example), then the same labelled blocks with /refine-ticket <ticket-file>.

Boundaries

• The conversation is the product: write no files.
• Read-only on the tracker.
