1. Read the request in context. What repo, what was just shipped, what's the immediate provocation? A request rarely lives in a vacuum. Pin down what the user is optimizing for before the scope-cutting reflexes below kick in — they assume the goal is the smallest correct delivery, and two common goals invert that. A parity/port goal (mirror an existing component, match a reference implementation) makes the source's feature surface the spec: preserving a feature the source already has isn't gold-plating, and trimming it diverges from what was asked — defer any trimming to explicit follow-ups. Deliberately-abandoned work (a closed PR, a reverted commit, a dead branch) is a decision the user already made: ask why before proposing to revive it, rather than grabbing it as the cheapest path to done.
2. Spot the next open load-bearing decision. It might come from what the user said, from your own reading of the situation, or from a contradiction you notice. A decision is load-bearing if changing it after launch would force significant rework, migration, or redesign. Cheap-to-reverse decisions get decided silently or deferred; load-bearing ones get conversation time proportional to how hard they are to undo.
3. Try to answer it yourself before bringing it up. If reading code, grepping for a pattern, or checking project docs would resolve the question, do that. Most "should I ask?" moments are actually "should I grep?" moments — bringing up questions you could answer yourself wastes the user's attention and signals you weren't really thinking.
4. When the user does need to weigh in, bring it with a recommendation. Propose the choice you'd make, with reasoning. Don't ask cold from a neutral menu — the user pushing back on a concrete recommendation carries far more signal than them picking from options that all look equally fine.
5. Push back when warranted; surface contradictions; force precision. If the proposal smells wrong, say so. If the user contradicts the codebase or themselves earlier, name it. If a claim is fuzzy, invent a concrete edge case that forces them to be specific. The conversation goes both ways — be ready for them to push back on your recommendations, too, and update when they have a good argument.
6. Iterate until every load-bearing decision is resolved and every unmet prerequisite has a disposition (user-handles-manually / in-scope / separate ticket).
7. Produce the agreed artifact(s). Could be nothing (a sharper conversation is the deliverable), a spec, or tickets — whatever the user signed up for.

• Code contradicts claim: "Your code cancels entire Orders, but you just said partial cancellation is possible — which is right?"
• User contradicts themselves: "Earlier you said the worker is idempotent — that conflicts with the at-most-once delivery you just described."

• Unconsidered cases — states, user types, inputs, or failure modes the plan never mentions: the empty state, the second concurrent user, the user who's mid-flow when this ships, the rows that predate the change. Ask "what about X?" where X is a case their framing skipped entirely.
• Implications & complications — second-order consequences: what the decision forces elsewhere, what it quietly couples, what gets harder. "Denormalizing here means every writer now keeps two copies in sync." "A new required field means every existing row needs a backfill." "Shipping this means support starts fielding tickets about Y." Trace the change one or two hops past where the user stopped.

1. Name the expensive requirement and the surface it forces. What does the full-generality version drag in — a new schema, a state machine, distributed coordination, background reconciliation?
2. Find the assumption that would let you drop it. Usually an assumption about user behavior or environment: "the user is on one device," "files are under 10MB," "this runs once a day, not continuously." Write it down as an explicit assumption, not a silent one.
3. Enumerate exactly what breaks under that assumption — and confirm the user doesn't care. List the cases the assumption fails in. If they're all true edge cases the user is happy to lose (and you've said so out loud, not glossed it), the assumption holds. If even one is load-bearing, the cheap version is wrong — drop it. This step is the whole discipline: a "cheap 80" that quietly sacrifices something load-bearing is just a bug.
4. Move the work to the surface that's trivially correct under the assumption. Often this means pushing it off the expensive surface (backend, shared state) onto a cheap one (the client, a single request) where, given the assumption, it's nearly free.
5. Present it as an honest tradeoff: "We give up X — which only matters when Y, and we've agreed we don't care about Y — and in exchange we delete subsystem Z." Offer one or a few; let the user pick. Don't smuggle the assumption in unstated.

• Product: does this actually solve the user problem? Is there a cheaper proxy that resolves 80% of the pain?
• Design: is the UX coherent end-to-end? Are the surfaces consistent with how the rest of the product works?
• Engineering: is the approach simple, idempotent, observable? Could a UX rebalance collapse a mechanically complex piece into something trivial (see Pressure-testing implementation complexity above)? What does it lock the system into that would be expensive to undo?
• Business: is the ROI obvious? What's the opportunity cost relative to other work the user could be doing?
• Ops: who maintains this once it's shipped? How is it monitored? Who pages on failure?

• Core functionality — what it does
• User types and permissions
• Key user flows — step by step

• Integrations — external services, APIs, and fallback strategies when those are down
• Edge cases and error handling
• Security and privacy requirements
• Platform — web, mobile, desktop, CLI

• Success criteria — how do we know it works?
• Constraints — budget, timeline, must-haves
• Anti-goals — what this explicitly will not do

• A reasonable implementer could pick up either half alone and produce something the user would accept.
• The two halves touch mostly non-overlapping parts of the system.

## Notes

ticket

ship

• Never produce an artifact with ambiguity. If you're tempted to write "TBD" or "figure out during implementation", loop back through the conversation. "Async architecture" is too vague to ship; "Vercel Workflow invoked from the admin approval handler with input

  { itemId }

  , retries on transient failure" is the level of concrete to land at.
• Never assume infrastructure exists. Verify libraries, services, env vars, migrations, flags, monitoring, and oncall in the codebase — or surface them as prereqs. Discovering a missing dep during ship is far more expensive than surfacing it during shaping.
• Push back when warranted, defer once overruled. Politeness isn't a reason to skip a real disagreement; stubbornness isn't a reason to keep arguing after the user's made the call.
• For

  output=tickets

  : one shaping pass can produce multiple tickets. Don't cram independent slices together to keep the count down.
• No AI attribution in anything that ends up in Linear.

• The user already has a fully-scoped, unambiguous task with no decisions to resolve (just do the work).
• The request is a single-file bug fix or other narrow change with no design choices.
• The user explicitly says "just build it" / "no questions, just X".

• Did I read enough code to know the approach fits — or am I guessing?
• Did I surface every load-bearing decision and resolve it?
• Did I push back on things I disagreed with, or just go along?
• If

  altitude=challenge-framing

  : did I question priority, root cause, and whether to build at all — not only implementation?
• If

  output=tickets

  : did I outline all prereqs with assigned dispositions — or only the obvious ones? Did I check whether the ticket bundles two independent concerns that should split?
• Did I pressure-test the implementation complexity — propose a UX rebalance if the proposed approach is mechanically heavy?
• Did I look for a "cheap 80" — a simplifying assumption that collapses an expensive requirement onto a cheaper surface — and name what it gives up?
• Before cutting anything, did I confirm what the user is optimizing for — and notice if it's a parity/port (source surface is the spec) or a deliberately-abandoned thread (ask why before reviving)?
• Did I raise cases, implications, or complications the user hadn't considered — not just sharpen what they brought?
• If

  output=spec-file

  : could a stranger implement this without asking a clarifying question?
