Our data is relational — users, teams, projects with clear relationships\n2. We need ACID transactions for billing operations\n3. JSON columns give us schema flexibility where needed\n4. Prisma/Drizzle have excellent Postgres support\n\n## Consequences\n\n- We need to manage connection pooling (use PgBouncer or Prisma's built-in pool)\n- Migrations must be backwards-compatible for zero-downtime deploys\n- We accept vertical scaling limits and will shard later if needed\n</code></pre>\n<h2>Workflow</h2>\n<ol>\n<li><strong>Identify</strong> the decision being made</li>\n<li><strong>Research</strong> the options (at least 2-3 alternatives)</li>\n<li><strong>Write</strong> the ADR using the template</li>\n<li><strong>Review</strong> with the team (PR or discussion)</li>\n<li><strong>Merge</strong> as accepted</li>\n<li><strong>Reference</strong> from code comments when relevant: <code>// See ADR-001</code></li>\n</ol>\n<h2>File Naming</h2>\n<pre><code>docs/decisions/\n├── 001-use-postgresql.md\n├── 002-adopt-trpc-over-rest.md\n├── 003-switch-to-pnpm.md\n└── template.md\n</code></pre>\n<h2>Tips</h2>\n<ul>\n<li>Keep ADRs short — 1-2 pages max</li>\n<li>Write them in the present tense (\"We choose X\" not \"We chose X\")</li>\n<li>It's OK to write an ADR after the fact if you forgot to write one during the decision</li>\n<li>Superseded ADRs should link to their replacement, not be deleted</li>\n<li>ADRs are not design docs — they capture the decision, not the full design</li>\n</ul>\n","files":[{"path":"SKILL.md","sizeBytes":2821,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
