Claude Code is no longer just a coding assistant — it’s becoming a policy-controlled execution layer, and the biggest wins now come from making agents stateless, auditable, and selectively specialized.

🔥 Supabase Evals: Real Repo Benchmarks Beat Vibes
The most actionable shift this week is benchmarking Claude Code on your own codebase instead of trusting generic model leaderboards. Supabase Evals lets you run supabase eval against real tasks so you can see where the agent fails on your stack, not someone else’s. Use it to identify brittle workflows before you spend more tokens on the wrong model.
📈 Federated MCP: Split the Monolith, Cut Integration Pain
MCP is scaling past the “one giant server” phase. The Supervisor + specialized MCP server pattern reduces the combinatorial mess of stuffing every tool into one process, and it’s the cleanest path for teams with many domains. If your MCP setup is turning into spaghetti, federate it now before tool routing and retries become your bottleneck.
✨ Stateless MCP 2.0: Fewer Sessions, Less Overhead
The new stateless direction is a direct attack on context bloat and session management overhead. Single-request tool calls make servers simpler to reason about and easier to scale, especially when paired with probing tools like mcp-explorer. If you’re still designing around long-lived state, you’re probably paying unnecessary latency and complexity tax.
Best Practices
Run supabase eval on your repo before changing prompts
Without this: you guess which tasks Claude Code is bad at and waste iterations on the wrong fixes. With this: you get repo-specific failures you can target immediately.
Use /context plus InstructionsLoaded to verify CLAUDE.md actually loaded
Without this: you rewrite rules blindly and still get lazy-loading misses from nested files or @imports. With this: you confirm the instruction chain first, then fix the real load path instead of the wording.

Tools & MCP
Supabase Evals — Benchmarks Claude Code on real Supabase tasks — exposes failure modes in your repo instead of synthetic toy tasks.
mcp-hub — Searches and installs from 13,000+ MCP servers — saves time guessing on npm and helps you find the right server fast.
mcp-explorer — Probes MCP servers to reveal capabilities and request shapes — cuts trial-and-error when adopting stateless MCP 2.0.
Multi-Agent Patterns
Supervisor + Specialized MCP Mesh
A top-level supervisor routes work to narrow MCP servers over stdio/SSE instead of forcing one server to do everything. This reduces integration blowup from monolithic tool sprawl and keeps each server focused on a single domain.
Subagent Trigger Routing via description
Make the subagent description the actual trigger condition, not just a label. This improves routing reliability when Claude Code is choosing specialists, especially when combined with /doctor to catch name collisions and bad tool declarations.
Independent Verification Session
Run a second Claude session, a different model, or a human acceptance pass against the same output. This catches the “2,000 tests passed, production still broke” failure mode where one agent’s blind spots are shared across the entire workflow.
