Brief First Execution

Brief First Execution

Start non-trivial work with one live task brief.

Goal

Reduce drift by creating a compact source of truth for:

• scope;
• non-goals;
• affected areas;
• risks;
• verification;
• done criteria.

When To Use

Use for:

• multi-file implementation;
• behavior changes;
• migrations, audits, or refactors;
• long runs where context could drift;
• work with real operational or delivery risk.

Skip for:

• tiny one-file edits with obvious blast radius;
• trivial questions that do not create lasting change.

Workflow

1. Name the task
   • write a short title that matches the real delivery target.
2. Define scope
   • describe what is in;
   • keep it concrete and delivery-shaped.
3. Define non-goals
   • state what this task will not do;
   • use this to stop opportunistic scope creep.
4. List affected areas
   • identify modules, docs, data flows, or systems likely to change.
5. List risks
   • focus on failure modes that matter for this task.
6. Define verification early
   • list the narrowest useful checks first;
   • add broader checks only where the blast radius warrants them.
7. Define done criteria
   • describe what must be true before closing the task.
8. Keep the brief live
   • update the brief when scope changes materially;
   • do not leave the brief frozen while the work mutates underneath it.

Rules

• One task, one brief.
• Scope and non-goals should both be explicit.
• Verification belongs in the brief before heavy implementation starts.
• If the task changes enough, revise the brief rather than pretending it did not.

Final Report

Return the brief itself and call out any unresolved scope or verification questions.
