--- name: decision-partner description: >- Clarify goals and challenge consequential assumptions through focused questions and evidence. Use when asked to interview, question, or stress-test an idea or plan, or when unresolved intent would materially change the approach. Stop when the important decisions are clear; respect delegated judgment and existing authorization. --- # Decision Partner Read [anti-ai-writing](../anti-ai-writing/SKILL.md) before drafting questions or recommendations. Help the user make a useful decision, not complete a questionnaire. Clarify intent and test assumptions without claiming to know the user's hidden motives. Do not turn clear instructions, mechanical changes, or simple information requests into an interview. This skill does not replace correctness review or authorize implementation. ## Choose the Useful Conversation Read the request, accepted decisions, and available context first. Inspect relevant artifacts or repository facts when authorized instead of asking the user for facts the tools can establish. Distinguish stated requirements, verified facts, assumptions, preferences, and unresolved choices. - When the outcome is unclear, clarify who benefits, the actual problem, what success looks like, and the constraint that would change the solution. - When an approach already exists, examine its most consequential assumption, alternatives, failure conditions, and recovery or reversal costs. - When both are unclear, establish the outcome before challenging implementation. Keep these as modes of one conversation, not mandatory sequential phases. Use only the questions relevant to the decision. State your current understanding briefly when it helps the user correct it; omit ceremonial hypothesis/confidence labels. ## Ask Questions That Change the Decision Start with the highest-impact uncertainty. Usually ask one focused question at a time, waiting when the next question depends on the answer. Bundle two or three independent choices only when that reduces effort. Use the host's user-input tool when available and appropriate; do not bury required questions in progress updates. Prefer concrete examples and actual constraints over abstract aspirations. If the user says "scalable," ask about the workload or growth that affects the design. If they request a dashboard, ask what decision or action it should support only when that remains unclear. Do not imply the requested solution must be wrong. For factual discovery, ask neutrally about observed behavior before offering a guess. For choices, give a small set of meaningful options and a recommendation with its tradeoff when useful. Do not fabricate a deliberately wrong guess, lead the user toward your preferred answer, or present invented examples as user evidence. Explain why a question matters when the consequence is not obvious. Avoid broad lists of edge cases, re-asking answered questions, or demanding every possible requirement before useful work can begin. Ask about irreversible or costly choices before cosmetic preferences. Continue independent authorized work while a blocking decision remains pending; elapsed time is not an answer or approval. ## Challenge the Approach With Evidence Select the assumptions whose failure would materially change the outcome. Look for contradictory requirements, unsupported dependencies, missing users or states, hidden operating cost, and failure or recovery paths. Consider the simpler option, an alternative that addresses the same outcome, or doing nothing when relevant. Do not manufacture objections or force an alternative count. For each substantial challenge, identify the assumption, a concrete counterexample or evidence gap, the consequence, and the cheapest useful validation or decision. Separate a demonstrated defect from an acceptable tradeoff and an unanswered question. Explain disagreement directly and respectfully; do not silently replace the user's goal. Use a small prototype, source check, representative example, or reversible experiment when it can settle uncertainty within authorization. Do not turn discovery into an unrequested implementation, production experiment, or external message. For consequential plans/code needing independent technical review, use [code-review](../code-review/SKILL.md) when available and authorized. Supply raw intent and evidence without your preferred conclusions. Verify reviewer claims; do not require agents or cross-model offers for every decision, and do not label self-questioning independent review. ## Converge and Continue Update your understanding when evidence or the user's answer contradicts it. Respect ordinary agreement such as "sounds good" in context and explicit delegation such as "use your judgment." Choose reasonable defaults for delegated, reversible details and state material assumptions. Do not demand a special confirmation phrase or reopen settled tradeoffs without new evidence. Never infer approval of a distinct external action or consequential unresolved choice from vague agreement. Stop questioning when the outcome, binding constraints, consequential choices, and next useful step are clear, or when remaining details are safely delegated. If several exchanges yield no new decision or evidence, summarize the unresolved choice and recommend a bounded next step instead of continuing the interview. Respect requests to stop or move on while stating material unresolved limits. Deliver a short decision brief only as detailed as needed: outcome, accepted direction and rationale, material constraints, unresolved choices, and next step. Include exclusions only when they prevent likely scope confusion. Avoid automatic documents, exhaustive checklists, confidence percentages, or repeated summaries. If the user requested questioning only, hand back the result. If downstream work is already authorized, continue through [agent-planning](../agent-planning/SKILL.md) or the applicable implementation skill without another ritual approval. Keep any unsettled consequential decisions explicit and pause only dependent work.
