Agent tooling
Routers, MCP servers, compaction, review gates, guards, and skills for coding agents.
The Claude Code accessory aisle. Routers, compaction, MCP, guards, and reviewers that speak probability. Agent tooling usually sits on the hot path: picking models, approving tool calls, compacting context, or scoring diffs. Favor READMEs that document latency budgets and failure modes. MCP listings should expose tool schemas so you know what state hits Jev.
