Agent Decision Snapshot & Replay
Build a developer tool that captures immutable decision-time snapshots for AI agents, including prompt state, retrieval context, tool inputs, outputs, and model configuration. The core value is deterministic replay, drift analysis, and audit-ready evidence that existing interpreter-level traces cannot provide.
これが重要な理由
You run AI agents that make branching decisions across prompts, retrieval, and tools, but when something goes wrong you can only see the code path that executed. That leaves you unable to reconstruct what context the model actually saw when it chose an action. Logs and runtime hooks show symptoms, not causes. Weeks later, replay is unreliable because retrieval results, configs, or tool outputs have changed. If you are responsible for debugging, audits, or incident response, you need a frozen artifact of the decision moment so your team can compare what should have happened against what did happen without guessing.

MVPの範囲 · 1～2週間
- Build a Python SDK wrapper that records prompt, retrieved context, tool call metadata, and model parameters to a local store.
- Create a minimal schema for immutable run snapshots with versioned artifacts.
- Add LangChain-compatible middleware hooks for LLM calls and tool invocations.
- Stand up a simple web UI showing a run timeline and raw snapshot fields.
- Implement secure redaction rules for secrets and PII before persistence.
- Add deterministic replay for captured runs using stored semantic inputs.
- Build run-to-run diffing for prompt, retrieval, config, and outputs.
- Add filters for failed runs, tool branches, and drift events.
- Ship a compliance export in JSON and PDF-friendly format.
- Instrument basic usage analytics and invite 5 design partners to test real incidents.

失敗する可能性がある理由
自己反論 — 最も重要な信頼のシグナル
- 1Teams may perceive this as nice-to-have observability rather than a must-have control unless replay clearly saves incident time.
- 2Capturing enough semantic context for useful replay without storing sensitive data may be harder than expected.
- 3Large observability vendors or agent frameworks could absorb this category once demand is proven.
エビデンスの概要
AIがこのインサイトをどのように統合したか — 逐語的な引用はありません
This was the most repeated theme in the discussion. Roughly half the comments focused on the same gap: runtime and interpreter hooks capture execution events but miss the model context that drove the decision. Multiple participants separately emphasized frozen prompt, retrieval, tool, and config state as the missing artifact for replay, compliance, and debugging, indicating a sharp and specific unmet need.
