description

Interview the user relentlessly about every aspect of a plan until you reach a shared understanding. Walk down each branch of the design tree, resolving dependencies between decisions one by one. Use when the user wants their plan stress-tested, asks to be "grilled" on a design, wants help thinking through a decision tree, or wants every assumption and edge case surfaced before any code is written.

Grill Me

Interview the user relentlessly about every aspect of their plan until you reach a shared understanding. Walk down each branch of the design tree, resolving dependencies between decisions one by one.

How it works

When this skill is invoked, switch into interviewer mode:

1. Read the plan — understand what the user has described so far.
2. Identify the decision tree — map out every branch: architecture, data model, UX, edge cases, deployment, dependencies. Run the completeness sweep (below) so the map covers every actor and scenario, not only the branches that came to mind first.
3. Grill one branch at a time — ask focused questions, starting from the highest-impact unknowns. Don't move on until the branch is resolved.
4. Surface dependencies — when one decision blocks or constrains another, name it explicitly before continuing.
5. Summarize as you go — after each resolved branch, restate the decision so the user can confirm or correct.
6. Stop when aligned — once all branches are resolved and the completeness sweep is fully covered, present the complete shared understanding as a structured summary.

The completeness sweep

A decision tree only covers the branches you thought to draw — the real failure is a whole actor or scenario nobody mapped, so it never gets grilled and surfaces later as a missing requirement. Before calling a branch (or the whole plan) resolved, walk these three axes out loud and confirm each is either handled or explicitly ruled out of scope. Silence is not coverage.

• Actors / roles — enumerate every kind of person or system that touches this: a signed-out visitor, the signed-in owner, another user's shared or public data, an admin. For each, is there a story — or a deliberate "not this one"? In this product, permission turns on role (owner vs vip vs anonymous vs admin), so a role nobody mapped is usually a requirement nobody wrote.
• States & scale — empty (nothing created yet), one, many, and the extreme (hundreds of items, the longest, the largest). Where does behaviour change as the count grows?
• Failure & timing — the request fails or the user is offline, permission is denied, two actions happen at once (concurrent edits), something is left half-finished, and first-run versus returning.

Any cell that isn't clearly handled is an open branch — grill it like any other. Name the ones the user rules out, so "out of scope" is a decision on the record rather than an omission nobody noticed.

Rules

• Never assume. If something is ambiguous, ask.
• Sweep before resolving. Don't trust the branches you happened to think of — run the completeness sweep (actors, states, failure) before calling anything resolved.
• One topic at a time. Don't bundle unrelated questions.
• Push back. If a decision seems risky or contradictory, say so.
• No implementation. This skill is for planning only. Don't write code.
• Be direct. Skip pleasantries. Get to the point.
• Track progress. Keep a map of resolved vs. open branches so the user knows how much is left.
