Project decisions

Why you chose X, in one place.

ADR-style decision records for solo founders and small teams. Future-you (or any AI) can ask "why X over Y?" and get the rationale, not a guess.

The pain

  • You picked Postgres over DynamoDB six months ago. Today you wonder whether to switch. You can't reconstruct the trade-offs you weighed back then.
  • Slack threads decay. "The decision" lives in a 40-message thread that's already been archived twice.
  • When you ask Claude to weigh a new option, it has no idea what you already rejected and why.
  • Onboarding a teammate means re-explaining every past decision from memory.

What you do in Memory.Wiki

  1. 1
    Write the decision as a short doc
    Context (what we knew), Options (what we considered), Decision (what we picked), Consequences (what we expect). 200-400 words. Memory.Wiki auto-tags the intent as "decision" after the next concept refresh.
  2. 2
    Cite the inputs
    Link the customer interview, the spike branch, the cost-model spreadsheet, the AI conversation that helped you think. Each link survives because Memory.Wiki URLs are permanent.
  3. 3
    Bundle by area
    Group all infra decisions, all pricing decisions, all hiring decisions into bundles. The hub log shows when each was made and who edited it.
  4. 4
    Recall when you revisit
    "Why did we pick Postgres?" → the Hub Assistant cites your own doc + its inputs. The AI now argues using your actual reasoning, not generic advice.

What you get back

  • Every decision has a permanent URL. Paste it into any AI when you need to revisit.
  • Concept index links decisions to the same source material — patterns in your own thinking become visible.
  • Teammates onboard themselves by reading the decisions log instead of asking you.
  • When you reverse a decision, the old doc stays — version history shows what changed and why.

Worked example

Example: ADR-007 — "Postgres over DynamoDB"

Context: 3 customer interviews flagged complex joins. Options: PG / Dynamo / Mongo with cost-model spreadsheet linked. Decision: PG. Consequences: "we'll feel pain at 100M rows; revisit then." Six months later, hub recall finds this in 1 second.
