Everyone has a framework for building agents. Nobody has a framework for operating them.
That's because operation looks boring from the outside. There's no demo. No "look what my agent can do" tweet. It's log analysis, token counting, memory auditing, and session lifecycle management. It's the difference between launching a rocket and keeping a space station running.
This checklist comes from running an autonomous AI agent 24/7 for over five weeks โ not in a sandbox, but in production handling real tasks with real consequences. Every item is something that either broke, degraded silently, or cost more than it should have before we caught it.
1. Session Health
Sessions are the heartbeat of agent operations. A session that grows unchecked becomes a session that hallucinates. These are the metrics that matter.
Token count per session. Track it continuously, not just at the end. Set a hard ceiling โ ours is 50K tokens. When the agent hits it, the session ends and a fresh one starts. Non-negotiable.
Context composition ratio. What percentage of tokens are system prompt vs. tool outputs vs. retrieved memory vs. conversation history? If tool outputs exceed 40% of context, your tools are dumping too much raw data. Summarize or truncate.
Session duration before degradation. Time how long before the agent starts making worse decisions. If it degrades after 2 hours, your session limit is 2 hours โ regardless of token count.
Restart recovery time. When a session ends and a new one starts, how long until the agent is fully productive? If it takes 10 minutes of context reloading, your session handoff needs work.
Rule of thumb: If your agent performs noticeably better in the first 30 minutes of a session vs. the last 30 minutes, your session ceiling is too high.
2. Memory System Health
Memory is where most agents silently fail. The system "works" โ it stores and retrieves โ but the retrieved context doesn't actually improve outcomes. These checks separate functional memory from useful memory.
Retrieval-to-action rate. When the agent retrieves a memory, does it change the agent's behavior? If you're retrieving 20 memories per task but only acting on 2, you're wasting 90% of your memory context budget on noise.
Error delta tracking. For each retrieval, measure the gap between expected outcome and actual outcome. If retrieved context consistently leads to worse outcomes (delta > 0.3), that context should be demoted or removed.
Memory freshness distribution. What percentage of your stored memories are less than 24 hours old? Less than 7 days? Over 30 days? Old memories without a decay mechanism become landmines โ technically correct but practically misleading.
Duplicate detection. Is the same fact stored multiple times with slight variations? Memory deduplication isn't just a storage problem โ duplicates waste context tokens and can cause the agent to over-weight certain facts.
Memory curation cadence. Who (or what) reviews and prunes memory? If the answer is "nobody," your memory system is a landfill. Schedule regular compaction โ daily for raw logs, weekly for curated knowledge.
Storage is trivial. Disk is cheap. Retrieval at the right moment with the right context โ that's the entire game.
3. Cost Tracking
Whether you're on per-token billing or a flat-rate plan with session limits, you need to know where your compute goes. "How much does it cost?" is the wrong question. The right question is "how much does it cost per successful outcome?"
Cost per completed task. Not cost per API call. Not cost per session. Cost per task the agent actually finished correctly. This is the number that determines whether your agent is economically viable.
Token waste ratio. Tokens spent on failed attempts, retries, and dead-end reasoning vs. tokens that contributed to successful outcomes. A 30%+ waste ratio means your agent is spinning before acting.
Tool call efficiency. Which tools are called most? Which return useful results? If your agent calls a search tool 5 times per task but only the first result matters, you're paying for 4 unnecessary calls.
Model ladder usage. Are you using the right model for each subtask? Routing classification tasks to GPT-4 when GPT-3.5 gets the same accuracy is pure waste. Track which tasks actually need the expensive model.
The hidden cost: Context window utilization on flat-rate plans. You're not paying per token, but a bloated context means fewer sessions per day, slower responses, and degraded quality. The cost is performance, not dollars.
4. Reliability & Error Recovery
An agent that works 95% of the time and fails catastrophically 5% of the time is worse than an agent that works 90% of the time and degrades gracefully. Here's what to monitor.
Task completion rate. Percentage of tasks completed correctly without human intervention. Track this daily. If it's declining, something is degrading โ and it's probably not the model.
Error categorization. Not just "it failed." Why did it fail? Tool timeout? Context overflow? Hallucinated a parameter? Misunderstood instructions? Each failure type has a different fix. Lumping them together hides patterns.
Recovery behavior. When the agent encounters an error, does it: (a) retry blindly, (b) try an alternative approach, (c) escalate to a human, or (d) silently continue with wrong data? Only (b) and (c) are acceptable. Track which one happens.
Cascading failure detection. One failed tool call shouldn't poison an entire session. Does your agent isolate failures, or does a single API timeout cause a chain of bad decisions? Test this explicitly.
Silent failure rate. The most dangerous metric. How often does the agent report success but actually produce incorrect results? This requires sampling and manual verification. If you're not doing it, you don't know your real reliability.
5. Operational Hygiene
The boring stuff that prevents spectacular failures. None of this is exciting. All of it matters.
Log retention and structure. Can you reconstruct what happened in any session from the last 7 days? If your logs are unstructured text dumps, they're useless for debugging. Structure matters more than volume.
Configuration drift detection. Your agent's system prompt, tool configs, and memory settings should be version-controlled. If someone changes a parameter and performance drops, you need to know what changed and when.
Credential rotation. API keys, tokens, service accounts. Are they rotated? Do they have minimal permissions? An agent with admin credentials to everything is a security incident waiting to happen.
Dependency health monitoring. Your agent depends on external APIs, databases, and services. Monitor their uptime independently. When the agent fails, you need to know if it's the agent or a dependency before you start debugging the wrong thing.
Session cleanup schedule. Old sessions, stale caches, orphaned processes. They accumulate. Schedule cleanup daily. We run automated cleanup at 3am and manual review during morning crons.
6. Multi-Agent Coordination (If Applicable)
Running multiple agents multiplies every operational challenge. These checks only apply if you're orchestrating more than one agent.
Inter-agent communication latency. How long does it take for one agent to receive output from another? Latency compounds in chains. A 3-second delay across 4 agents is 12 seconds of dead time per interaction.
Shared state consistency. If two agents read the same memory or database, are they seeing the same data? Race conditions in agent coordination cause subtle bugs that are extremely hard to reproduce.
Workload distribution. Is one agent handling 80% of the work while others idle? Unbalanced orchestration means you're paying for agents that aren't contributing. Track task throughput per agent.
Using This Checklist
You don't need to implement everything on day one. Start with session health and cost tracking โ those are the two areas where problems compound fastest. Add memory health monitoring in week two. Build toward full coverage over a month.
The point isn't to check every box. It's to know which boxes you're not checking and make a conscious decision about the risk you're accepting.
