After six months of daily agent use, I’ve settled on a setup that covers every scenario. It’s not one tool. It’s a layered system — and the layers matter more than the individual tools.
The Three Layers
Layer 1: Quick edits (Cursor) — For single-file changes, fixing typos, writing tests, any task that takes under 5 minutes. Cursor’s inline editing is faster than typing. I don’t leave my editor. I don’t context-switch.
Layer 2: Complex work (Claude Code) — For multi-file refactors, debugging across modules, architecture decisions. Claude Code’s reasoning depth matters here. A 40-file refactor that would take Cursor 10 iterations takes Claude Code one pass.
Layer 3: Automation (Hermes) — For cron jobs, scheduled tasks, background agents. Hermes’s cron system runs code review every morning at 9 AM, dependency updates every Friday, and a weekly security audit. I don’t think about these — they just happen.
What Each Layer Actually Does (Real Examples)
After six months, the pattern is clear. Each layer handles a specific class of work:
Layer 1 tasks (under 5 minutes)
- Fix a lint error across three files
- Add a unit test for a function that just broke
- Rename a variable across a module
- Update a config value
- Write a one-off script to migrate data
These are tasks where the cognitive load of switching to a terminal agent would cost more time than the edit itself. Cursor keeps me in flow.
Layer 2 tasks (10–60 minutes of agent time)
- Refactor authentication middleware to support OAuth
- Debug why a specific API endpoint returns 500 under load
- Implement a new feature that touches 15+ files
- Review a large PR and suggest architectural improvements
- Port a module from JavaScript to TypeScript
These require cross-file reasoning. The agent needs to understand how files relate, hold context across multiple files, and make decisions that affect architecture. Claude Code handles this better than any inline editor because it reads the full repo context before acting.
Layer 3 tasks (background, no supervision)
- Daily dependency audit (
npm audit,pip-audit) - Weekly AGENTS.md drift detection (verify agent instructions are still followed)
- Scheduled security scans (check for leaked credentials, exposed secrets)
- Automated PR reviews triggered by webhooks
- Nightly build verification
These are tasks I don’t want to think about. They should run, complete, and only alert me when something fails.
Why Not One Agent
Every agent has strengths. Cursor is fastest for inline edits. Claude Code is best at reasoning about complex codebases. Hermes is best at automation. Using one for everything means compromising on at least one dimension.
The practical failures of single-agent setups:
- Cursor for complex refactors: it loses context after ~5 files and needs repeated manual nudging
- Claude Code for quick edits: opening a terminal, waiting for context load, then running a one-line fix takes 30 seconds instead of 5
- Hermes for interactive work: it excels at autonomous tasks but interactive debugging requires a human-in-the-loop editor
The cost argument against multiple agents is weak. Here’s a realistic monthly breakdown:
| Tool | Plan | Monthly Cost |
|---|---|---|
| Cursor | Pro | $20 |
| Claude | Pro | $20 |
| Hermes | BYO keys | ~$5–15 (token costs) |
| Total | $45–55/mo |
That’s less than most developer tool subscriptions, and it covers the full workflow spectrum.
The Handoff Workflow
My setup works because the agents don’t compete — they pass work between them:
- Cursor handles the quick edit loop during development
- Claude Code handles the complex work that Cursor can’t
- Hermes handles the maintenance work that neither should do in real-time
The key insight: each agent has a job description. Cursor doesn’t do big refactors. Claude Code doesn’t do quick edits. Hermes doesn’t do interactive work. By respecting each agent’s strengths, the system produces better results than any single agent could.
This matters because agents fail in predictable ways when forced outside their lane. Cursor’s context window is the bottleneck for complex work. Claude Code’s startup overhead makes quick edits wasteful. Hermes’s asynchronous nature makes real-time collaboration clunky.
Common Mistakes When Moving to Multi-Agent
- Overlapping responsibilities — If two agents can do the same task, you’ll waste time deciding which one to use. Define clear boundaries.
- Ignoring context boundaries — Claude Code’s project context doesn’t automatically sync with Cursor’s workspace. If you edit a file in Cursor, Claude Code won’t see those changes until you start a new session.
- Skipping the AGENTS.md setup — Both Claude Code and Hermes read AGENTS.md. Without it, they default to generic behavior. Spend 30 minutes writing one; it pays for itself in a week.
- Treating automation as optional — The automation layer (Hermes, cron jobs) is what separates a good setup from a great one. Manual maintenance is the first thing you skip when busy, and that’s when security incidents happen.
Security Considerations
Each agent has different credential exposure profiles. When you split work across multiple agents:
- Cursor processes code through its proxy — audit what API keys it can see
- Claude Code runs through Anthropic’s API — review what environment variables it accesses
- Hermes with local models keeps everything on your machine — the safest option for sensitive code
At minimum, use separate .env files for each agent scope. Don’t give Cursor production database credentials just because Claude Code needs them for a migration.
How to Start
If you’re using one agent today, ask yourself: what tasks does it handle poorly? That’s where you add a second agent.
Practical first steps:
- Audit your current tasks — For one week, categorize every agent interaction as “quick edit,” “complex reasoning,” or “recurring automation.”
- Match to layers — Quick edits → editor agent. Complex reasoning → terminal agent. Recurring automation → cron agent.
- Start with two — Don’t adopt all three at once. Add one new agent for the task category you handle most poorly.
- Write an AGENTS.md — Document your project’s conventions, architecture, and rules. Every agent should read it.
The goal isn’t to collect tools. It’s to cover your workflow gaps. Start with Claude Code or Cursor as your primary. Add Hermes when you want automation. Add Cursor or Codex when you want parallel execution.
The multi-agent future isn’t about replacing one tool with another. It’s about having the right tool for each job.
