Claude doesn’t have your project in its head until you point at it. Cold-start get cold-start answers.
The five-part shape of an opener that gives Claude what it needs:
- Location — the file, folder, page, or document involved
- Symptom — what’s currently happening
- Repro — how to make the symptom happen (URL, test name, user step)
- Desired — what should happen instead
- Constraint (optional) — anything that’s locked in (don’t break X, must use Y)
Bad: “Fix the dashboard.”
Good: “In src/pages/dashboard.tsx, the empty-state placeholder is overlapping the chart legend. Repro: log in as empty@example.com and open /dashboard. I want the placeholder centred and the legend hidden when there’s no data.”
Notice: the good version is one short paragraph, not a wall of text. Specificity beats length.
When the prompt is more open than a bug fix — exploring a new area, planning a refactor — front-load the grounding with the “Read X. Then ask Y” pattern:
Read
src/services/billing.tsandsrc/routes/billing.ts. Then tell me where invoice totals are computed and whether there’s a single source of truth.
Two sentences. First sets context, second asks the question. Stops Claude from guessing what file you meant.
