Debugging Agent for AI Code Assistants

A local debugging tool that runs alongside AI coding agents (Claude, Copilot, Cursor) to provide full observability and prevent 'PR slop' - plausible-looking code that fails in production. It captures traces, metrics, and request/response data that traditional observability stacks miss.

AI coding agents are now mainstream enough that "vibe coding" failures and PR slop are documented problems with real engineering team pain, making the timing legitimate rather than speculative. No clear incumbent owns this specific layer — traditional APM tools like Datadog weren't built for agent request/response traces, and the agent vendors themselves have no incentive to expose their failures. The $5k–20k/mo band is plausible only if this lands as a team-level devtool with per-seat pricing, since individual developers rarely pay for debugging utilities consistently enough to sustain that range. The biggest risk is that the major agent platforms — Cursor, Copilot, Claude's API — build native observability into their own products, collapsing the wedge before there's enough adoption to pivot.
