Growth engineering

Fontana growth engineering turns each MiniSpec and MegaSpec delivery into searchable institutional knowledge. You capture durable fixes and conventions in docs/solutions/; agents consult that store before planning and assurance so the next task starts closer to done.

What you get

Section titled “What you get”
  • docs/solutions/ - YAML-frontmatter learnings (bug track and knowledge track) organised by category.
  • learnings-researcher - Grep-first search of the solutions store during review, MegaSpec impact/planning, and assurance.
  • /growth-capture - Interactive, headless, or log capture of a solved problem. A full /🫡 log / LOGTHIS runs the Growth phase: introspect the session, then write docs/solutions/ and focused .cursor/rules so the same class of bug does not recur. LOGTHIS fast skips that phase when you only need the changelog.
  • Tiered review personas - Always-on validator, reviewer, and learnings search; conditional Convex public-surface and adversarial reviewers when path triggers match.

Operator flow

Section titled “Operator flow”
  1. Gather and implement with MiniSpec (/minispec) or MegaSpec (/megaspec) as usual.
  2. During review and assurance, agents pull prior learnings from docs/solutions/ when relevant.
  3. After assurance and tidy-up, a full /🫡 log / LOGTHIS runs the Growth phase (introspect bugs and conventions; write solutions and Cursor rules). Agents record No growth delta only when introspection finds nothing durable. Type LOGTHIS fast when you want the changelog without Growth or spec cleanup.
