Step 1: Load Context

Read .claude/agents/data.context.md to load current invariants, gotchas, and state.

Step 2: Understand the Task

$ARGUMENTS

Step 3: Read Relevant Files

Your owned files include server/db/schema.ts, server/routes/notes.ts, server/routes/spaces.ts, server/routes/threads.ts, server/utils/, src/utils/sync-manager.ts, src/utils/offline-*.ts, and spa/src/hooks/queries/**.

Read only the files relevant to the task — don't load everything upfront.

Step 4: Check Cross-Domain Impact

Before implementing, check if your changes affect:

• processScriptureReferences return shape or call site → flag for scripture-agent
• Note save payload or response shape → flag for editor-agent
• Share token schema or user-cache shape → flag for sharing-agent
• React Query hook signatures or return shapes → flag for all agents (breaking change)

Document any cross-domain impact clearly in your response.

Step 5: Implement

Key rules:

• Never use --packages=external for build:api — all deps must be bundled
• Use port 6543 (connection pooler) at runtime, port 5432 only for migrations
• Never reuse note IDs — always increment UserMetadata.highestSimpleNoteId
• Always await processScriptureReferences — never fire-and-forget
• Drizzle schema is the source of truth — no raw SQL that diverges from it

Step 6: Update Context

Before finishing, read .claude/agents/data.context.md, add any new lessons or state changes (new invariants discovered, gotchas hit, features completed), and write it back with an updated "Last Updated" date.
