One Shared Managed Agent Definition, Overridden Per Session
A design for collapsing four near-identical Managed Agents into one base definition, using agent version pinning and session-local overrides — with a validated factory and the traps I hit along the way.
Claude API × Convex: Reactive AI Apps — Data Flow, Streaming, and Agent Patterns
How to combine Convex's reactive database with the Claude API to build chat and agent applications that hold up in production. Covers schema design, the Action/Mutation/Query boundary, streaming, tool-call state, and the cold-start pitfalls nobody warns you about.
When a Tool Result Is Too Big and Melts Your Context Window: Designing Cursor-Based Pagination
When a list tool returns hundreds of rows at once, an agent's context can collapse in a single call. Here is a cursor-based pagination design that keeps tool output small and protects your token budget, with working code.
Running Subagents in Parallel Without One Failure Sinking the Whole Run
A fan-out / fan-in design for running several subagents in parallel, covering token budgeting, a result contract, and partial-failure handling. Includes an implementation where one branch can fail without stopping the rest, plus measured numbers.
Keep a Decision Rationale Ledger for Autonomous Agents — So You Can Explain 'Why' Later
When an autonomous agent takes hard-to-reverse actions like a production deploy or a bulk delete, capture the chosen option, rejected alternatives, and assumptions in a structured ledger. Includes structured output, an append-only log, and tiering by impact.
