Per-user AI API spend attribution
map requests to users/features for billing

AI features create opaque, runaway API bills and teams can’t tie spend to users or features. Instrument requests, capture prompt-level telemetry, and auto-allocate cost per user/feature so engineering, product, and finance can act.

Turn PRDs into focused coding-agent tasks
extract specs & tests

PRDs are too broad and noisy for coding agents. Convert PRDs into actionable, prioritized agent tasks, API contracts, and test suites so LLMs produce reliable, integrable code instead of guesswork.

Cancel server response body streams on client disconnects

Clients disconnecting during long-lived HTTP streams can leak per-client resources because response body streams aren’t cancelled. Provide runtime + SDK hooks to propagate abort signals into response streams and auto-cleanup resources.

Auto-switch Monaco model to TypeScript for correct TS parsing

Problem: web playgrounds using a JS model show TypeScript-only diagnostics even when TypeScript is selected. Solution: detect TS language and load an index.tsx model with language:'typescript' so Monaco's TS service parses TS syntax natively; keep Flow on JS model.

Auto-heal & observability for PostgREST schema-cache failures (PGRST002)

Developers using PostgREST/Supabase face persistent PGRST002 (schema cache) 503s that break APIs and waste on-call time. A managed devtool that detects, diagnoses, and auto-remediates schema-cache and permission issues plus guided fixes reduces downtime and toil.

RAG demos fail: hidden retrieval & metadata bugs
automated RAG debugger

RAG apps silently fail when retrieval returns wrong chunks or metadata mapping is off. Build an automated RAG-debugger that traces provenance, tests retrieval correctness, simulates queries, and surfaces data/embedding issues before demos or production rollouts.

App-router back-navigation hydration checker + auto dev-time fixes

Developers waste hours debugging App Router back-navigation hydration regressions in Next.js dev mode. A dev-time tool that detects, explains, and auto-fixes/window-patches these hydration issues (with repro capture + one-click patches) speeds fixes and reduces CI churn.

Keep Profiler "What changed" usable: sticky, searchable diffs for long render histories

React Profiler's "What changed" pane becomes unusable for fibers with long commit histories. Build a companion that pins, summarizes, and time-travels diffs (AI-summarized + searchable) so devs inspect renders without losing context.
