We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Brief

Purpose

Start shaping with a concise brief.md.

Inputs

  • Problem, why now, evidence, success.
  • Appetite/timebox + constraints.
  • Goals + non-goals.
  • In/out scope (perimeter).
  • Key flows + links (breadboard, risks, spikes).
  • Top risks + unknowns.
  • Open questions.
  • If missing, use ask-questions-if-underspecified.

Workflow

1) Read any existing brief + inputs. 2) Ask questions to clarify using ask-questions-if-underspecified skill. 3) Draft brief.md. 4) Keep 1-2 pages. Link out instead of dumping details. 4) Ensure: problem alignment, goals/non-goals, perimeter, de-scope, risks/unknowns (<=10), open questions (<=10), shaping decision placeholder. 6) Return updated brief.md.

Output

  • brief.md
