Agent Failure Forensics Sprint — Sample Deliverable Brief

Product: Agent Failure Forensics Sprint — $750 flat

Pain point: Production AI agents fail silently; no replay-fixture monitoring

Buyer persona: Head of platform / staff engineer on agent infra, AI agent product team (Series A SaaS)

What you receive for $750

A structured forensics package built from your submitted agent logs — delivered in 5 business days.

Deliverable 1: Exception Ledger

Every agent action that deviated from expected behavior is classified and ranked by impact.

ID	Classification	Agent Action	Confidence
EXC-001	MATCHED — Reasoning loop	Agent re-called same model 22× in 30 min after ambiguous tool response. No circuit breaker. Token burn: ~$0.87/retry.	HIGH
EXC-002	UNMATCHED — Silent schema mismatch	Tool `db.query` ran with hallucinated `user_id=usr_99X`. Empty result set, no exception raised. Agent continued.	HIGH
EXC-003	DUPLICATE — Idempotency hole	Tool `send_email` fired twice with same idempotency key, different body payload (LLM re-sent after perceived timeout). Double delivery confirmed via SMTP log.	HIGH
EXC-004	AMBIGUOUS — Stale config cascade	Tool `fetch_config` returned 404. Agent used cached stale config (18h old) without alerting. Downstream system operated on wrong config.	LOW

Coverage: 4/4 records classified. 2 HIGH, 1 MED, 1 LOW confidence.

Top pattern: EXC-001 consumed 22× expected token budget per user request.

Deliverable 2: Root Cause Bite-Size Summary

Three sentences a non-technical stakeholder can act on:

EXC-001 (reasoning loop) was caused by an ambiguous tool response that triggered re-invocation without a loop-detection guard. EXC-002 (silent schema mismatch) occurred because no schema validation layer exists between tool output and downstream consumption. EXC-003 (double email delivery) is an idempotency-key collision under perceived timeout — fixable with a deduplication write-before-read check.

Deliverable 3: Fix Priority Queue

Fix	Effort	Business Impact	Recommended First
Add circuit breaker for reasoning loops (EXC-001)	2–4 hrs	$20.08/hr per active loop × agent count	✅ Do first
Add schema validation layer (EXC-002)	4–8 hrs	Silent data corruption risk eliminated	✅ Do second
Idempotency key deduplication (EXC-003)	1–2 hrs	Regulatory/UX risk from double-sends	✅ Do third
Config freshness TTL + alert (EXC-004)	2–3 hrs	Low unless downstream is compliance-critical	Schedule
