What makes a good AI agent architecture?

Good AI agent architectures have: (1) Clear separation of concerns - tool execution, state management, and decision logic are distinct, (2) Explicit safety boundaries - define what can be done autonomously vs. what needs confirmation, (3) Robust error handling - graceful degradation when tools fail, (4) Transparent operation - users can see what the agent is doing and why, (5) State persistence - agents can resume work after interruptions. The best architectures balance autonomy with safety and provide escape hatches when things go wrong.

How do I decide when an agent should ask for confirmation?

Use this framework: (1) Reversible + Local = Autonomous (reading files, running tests), (2) Reversible + External = Ask or notify (creating draft PR, sending test email), (3) Irreversible + Local = Ask (deleting files, modifying configs), (4) Irreversible + External = Always confirm (deploying to production, charging payment method, deleting production data). When in doubt, default to asking - you can always reduce friction later once users trust the agent.

Should I build one multi-purpose agent or multiple specialized agents?

For complex systems, use specialized agents coordinated by a main agent. This is called the "subagent pattern" in GPT-5 and Claude Opus 4.7 documentation. Benefits: (1) Each agent has focused context and tools, (2) Easier to test and debug, (3) Can run in parallel, (4) Simpler prompts per agent. Use a single agent only when the task is inherently unified and requires shared state across all operations.

How do I handle long-running tasks that exceed token limits?

Use state persistence and context compaction: (1) Save progress to files or database at regular intervals, (2) Summarize completed work into compact progress notes, (3) Design agents to resume from saved state, (4) Use the context_awareness feature in Claude 4.7 which automatically manages context, (5) Break work into atomic checkpoints - each checkpoint should be independently resumable. The agent should be able to restart from the last checkpoint if context resets.

Frequently Asked Questions

Best Practices

Critical Best Practices

Use Tool Preambles

critical

Provide clear progress updates before calling tools so users can follow the agent's work. This improves transparency and user experience during long operations.

Example:

"Before calling search tools, explain: "I'm going to search our knowledge base for recent updates on this topic...""

Source: openai

Define Persistence Behavior

critical

Specify when the agent should continue working vs. asking for clarification. Set clear stop conditions to avoid premature termination or endless loops.

Example:

"Only stop when: (1) Task is fully complete, (2) User explicitly asks to stop, or (3) You encounter an unrecoverable error."

Source: openai

Define Error Handling Strategy

critical

Specify how agents should handle errors, missing data, and edge cases. Should they retry, escalate, or proceed with uncertainty?

Source: custom

Set Safety Boundaries

critical

Define which actions require confirmation (destructive operations, external API calls, file deletions) vs. which can be done autonomously.

Example:

"Ask before: deleting files, making API calls that cost money, or modifying production databases."

Source: claude

Recommended Best Practices

Enable Parallel Tool Execution

recommended

Allow agents to call multiple independent tools simultaneously for faster execution. Critical for research and multi-step workflows.

Example:

"When gathering context, run file reads and searches in parallel rather than sequentially."
