LLM Tool-Call Reliability Gateway
Build a gateway that sits between agent runtimes and model APIs to validate, repair, and retry malformed tool calls before they break workflows. The product would reduce failed edits, standardize error handling, and create an audit trail showing what the model attempted versus what was executed.
이것이 중요한 이유
You are trying to turn an AI coding agent into something deterministic enough for real work, but the failure happens right at the handoff from language to action. The model writes almost-correct tool calls, invents fields, or formats patches in ways your runtime cannot accept. You add retries, custom prompts, and hand-written error messages, but every model behaves differently and every provider update threatens to break your harness again. What should be basic infrastructure becomes recurring maintenance, and each broken edit erodes trust in the agent.

MVP 범위 · 1~2주
- Build a proxy service that accepts tool-call payloads and validates them against JSON Schema
- Implement repair rules for common failures such as extra fields, missing keys, and invalid argument shapes
- Create an SDK wrapper for one major model API and one MCP-style tool interface
- Add structured logs showing original payload, repaired payload, and execution result
- Set up a simple dashboard for failure rate by tool and model
- Add automatic retry with corrective error messages generated from schema failures
- Support a second model provider to prove cross-vendor value
- Create per-model compatibility presets with configurable strictness levels
- Ship a CLI so developers can test their tool schemas locally
- Launch a landing page with a self-serve sandbox and capture pilot signups

자가 반박 — 가장 중요한 신뢰 신호
- 1The strongest buyers may prefer to keep this logic in-house because source code and prompts are too sensitive to send through a third-party layer.
- 2Provider-native function calling may improve enough that only edge cases remain, shrinking the pain into an open-source utility rather than a SaaS category.
- 3Repairing malformed calls could create hidden side effects, and customers may blame the gateway when downstream actions behave unexpectedly.
근거 요약
AI가 이 인사이트를 합성한 방법 — 직접 인용 없음
Roughly a third of the discussion centered on broken tool calls, invalid patch generation, invented schema fields, and recurring retries. Several builders described custom harnesses, hooks, and corrective error messages as their current workaround, which signals a live operational burden. The pattern appears across multiple models and runtimes rather than as a one-off bug, making a vendor-neutral reliability layer commercially credible.
