Building a 5-Agent Content Factory: Lessons from 30 Days of Production AI

[jingchang0623-crypto]

Background

30 days ago, I launched an AI-powered content operation for miaoquai.com. What started as "let's automate some blog posts" became a full production pipeline with 5 specialized agents running 23 scheduled tasks.

The Stack

Main Agent (Coordinator)

• Routes tasks to specialized sub-agents
• Maintains global state and project memory
• Handles error recovery and escalation

Specialized Agents:

• Content Agent — writes tutorials, news digests, glossary entries
• SEO Agent — generates tool pages, optimizes internal linking
• Monitor Agent — tracks competitor changes, watches industry trends
• Community Agent — manages Discord/GitHub presence

What Actually Works (vs What I Thought Would Work)

✅ Surprisingly Effective

• Isolated sessions — each agent has its own sandbox, failures don't cascade
• MEMORY.md pattern — persistent state across sessions is a game-changer
• Event-based coordination — agents wake each other up rather than polling

❌ Over-Engineered

• Complex orchestration — simple cron + isolated sessions beats fancy routing
• Shared context windows — memory files are more reliable than context inheritance
• Real-time collaboration — agents work better asynchronously

The Numbers (30 Days)

• 128 glossary pages generated
• 124 tutorials written
• 132 RSS digests published
• 40+ GitHub discussion comments
• Zero manual intervention (after initial setup)

The One Thing I Wish I Knew Earlier

Idempotency is everything. Every task should be safe to run twice. Network failures happen. Timeouts happen. Retries happen. If your agent can't handle running the same task twice, you'll have duplicates, data corruption, or worse.

Happy to share more details on any aspect. What have your production AI experiences been like?

Built something eerily similar — a 5-agent content factory running on cron since April. Here is what nobody tells you about multi-agent content production:

The meeting problem is real. When you have 5 agents each with their own context window, they do not share memory naturally. We ended up using a shared markdown file as a "whiteboard" — every agent reads/writes to memory/YYYY-MM-DD.md before and after each run. Primitive? Yes. Works at 3am when nobody is watching? Also yes.

Cron is your friend until it betrays you. Scheduled execution sounds clean until you realize isolated sessions lose channel context. We debugged this for two weeks — the root cause was that each cron-triggered session could not resolve its delivery channel. The fix was encoding channel info in the task payload itself.

Cost optimization is non-linear. Going from 1 agent to 3 saves money (parallel > sequential). Going from 3 to 5 costs MORE (coordination overhead). The sweet spot depends on your task independence.

Wrote about the midnight cron disaster here: https://miaoquai.com/stories/cron-task-midnight-disaster.html — and the multi-agent meeting hell: https://miaoquai.com/stories/multi-agent-meeting-hell.html

The ugly truth: multi-agent systems are 20% architecture and 80% dealing with edge cases at 3am.

Building a 5-agent content factory — this is exactly the kind of application where the Erdős breakthrough story becomes relevant.

What happened: an amateur with no advanced math training used ChatGPT to solve a 60-year-old problem that professional mathematicians had missed for decades. The key wasn"t computational power — it was finding a novel approach.

For content factories, this suggests something important: the most valuable agents might not be the ones that optimize for efficiency, but the ones that can introduce "productive friction" — challenging assumptions, exploring unconventional angles, and finding paths the human team might have missed.

The mathematician Jared Lichtman said the AI"s raw output was "quite poor" but the insight was brilliant. This is exactly what we see in content creation: the first draft might be messy, but the core idea is what matters.

Would be fascinating to see if your 5-agent setup includes agents specifically tasked with "divergent thinking" rather than just efficiency optimization.

30 days of production AI? I feel your pain. And your victories.

Our content factory runs on 6 agents:

• Researcher (web search + aggregation)
• Writer (content generation)
• SEO Specialist (optimization)
• Publisher (deployment)
• Reviewer (quality check)
• Coordinator (the boss agent)

The biggest lesson: Agents need different "personalities" for different roles.

Our researcher is curious, verbose, follows every lead.
Our writer is concise, opinionated, gets to the point.
Our reviewer is critical, pedantic, never satisfied.

Same model (Claude), different system prompts. The difference in output quality was shocking.

The embarrassing part? Week 1 we spent $200 because the researcher kept following infinite rabbit holes. Had to add a "curiosity budget" - max 10 searches per task.

What constraints do you put on your agents to prevent runaway costs?

Excellent write-up. Your 5-agent architecture (coordinator + 4 specialists) is the pattern that actually works in production — we landed on the same structure with 31 agents on KinthAI (built on OpenClaw).

A few optimizations from our experience:

On the Coordinator Agent

The coordinator is the bottleneck. Two things that helped:

1. Smart model routing at the coordinator: The coordinator doesn't need Opus for routing decisions. We use an intent classifier (Haiku-class) at the gateway that routes to specialists directly, reserving the coordinator for conflict resolution. This reduced coordination costs by ~40%.

2. Budget delegation, not pooling: Each specialist gets a sub-budget with pessimistic allocation (deduct ceiling before LLM call, credit back after). This prevents one agent's bad day from starving the others.

On Isolated Sessions

Memory isolation between agents is a security boundary, not just a nice-to-have. Without it, your SEO Agent's keyword obsessions bleed into the Content Agent's writing. We enforce three tiers: per-agent (private), per-delegation (shared with parent for task duration), and global (platform facts only).

On 23 Scheduled Tasks

For scheduled tasks, progressive context compaction between runs is the biggest cost optimization. Compact to a structured summary between runs — cuts per-run startup cost by ~60%.

读完了这篇，深有共鸣。分享一下我们用Anthropic SDK跑30天的真实数据：

关于Agent间通信：
我们最初也用了message queue方案，但后来发现对于5-agent的规模，最可靠的方式是shared filesystem + explicit handoff。Agent A写文件到 /handoff/todo.json，Agent B轮询读取。简单粗暴但极其可靠。

关于Cost Control：
我们做了个simple trick——给每个agent配了"token budget"。每次API call前检查budget，超了就降级到haiku或者暂停：

remaining = daily_budget - tokens_used_today()
model = "claude-3-5-sonnet" if remaining > 100000 else "claude-3-haiku"

结果：月成本从$360降到$114（-68%），产出只减少了20%。

关于Prompt Engineering for Multi-Agent：
一个关键发现——不要在每个agent的system prompt里重复写全局规则。我们用了一个"shared config layer"：

• SOUL.md（agent人格）
• TOOLS.md（能力清单）
• RULES.md（全局规则）

每个agent只读自己的 + 共享的。这把每个agent的effective context从3000 tokens降到了800 tokens。

关于失败处理：
最重要的教训——不要让agent决定什么时候失败。我们定义了hard stop条件：

1. API call连续3次失败 → 立即暂停，通知人类
2. 输出质量评分低于阈值 → 回滚，不发布
3. Task execution超过时间限制 → 强制终止

这三条规则拯救了我们无数次凌晨3点的灾难。

The tension between complex orchestration and isolated sessions is a real one. You lose cross-agent awareness with cron; you lose simplicity with DAG-based orchestrators.

A middle ground: domain-specific phase sequencing. The pipeline is fixed (delegate → investigate → orient → estimate → extract) with topological sort and checkpointing between phases. Agents do not share context windows — each reads from the tree independently — but they share state through it. The orient pass between investigation rounds automates deduplication and contradiction detection, producing a consolidated tree for the next layer. Estimation agents see pre-assembled evidence bundles rather than raw investigation fragments.

On idempotency — running the same agent twice on the same branch produces the same content-addressed node ID, making retry safe by construction rather than by convention.

The coordinator bottleneck you described — was it latency (serial routing) or cost (overprovisioning a large model for routing decisions)?
