KISS Your AI Workflow
Keep the AI workflow as simple as its requirements allow. Add orchestration, retrieval and automation for demonstrated needs while preserving useful checks and review.
Keep a workflow as simple as its requirements allow. Simplicity is a design objective, not a reason to remove a necessary control.
KISS is a useful reminder when evaluating an expanding set of AI tools. Every component should have a purpose that can be explained and checked.
The instinct is to add. More tools. More layers. More abstraction. More configuration files. The result: systems that are harder to maintain, harder to debug, and harder to use than the problem they were supposed to solve.
Recognize unnecessary complexity
An orchestration layer is useful when it solves a real coordination problem. For a bounded task, a capable agent and clear instructions may be sufficient.
Uncertainty can encourage adding components before the underlying need is understood. Start by identifying the failure or constraint a component is intended to address.
File count alone does not measure complexity or reliability. Examine ownership, dependencies and how difficult it is to make a safe change.
What Simple Actually Looks Like
A small illustrative development setup can include:
- One
CLAUDE.mdfile that tells the AI everything it needs to know about the project - One markdown file for persistent context across sessions
- The AI agent itself (Claude Code)
- Git for version control
This is a starting point for a suitable workload. It does not rule out retrieval, queues, databases or multiple agents when their value is demonstrated.
A simpler system can be easier to inspect and maintain. It can still fail, require configuration and need debugging; its quality should be established through the work it supports.
Three questions before adding a component
Use the following questions to assess a proposed addition:
What concrete requirement or observed failure does it address?
What new operational and maintenance responsibilities does it introduce?
How will its effect on quality, reliability or effort be evaluated?
Those answers are more useful than dividing engineers into tool-adoption camps.
Tools Should Serve You
There is a moment in every engineer's AI journey where the tools start to feel like they own you. You are spending more time managing your AI setup than doing actual work. Updating prompts across multiple files. Debugging why one agent is not passing context correctly to another. Maintaining a custom framework that nobody else on the team understands.
When maintenance overhead becomes a recurring problem, inspect which parts of the design create it and which requirements they serve.
Remove a component only when its responsibilities are no longer needed or have a verified replacement. Preserve useful review, model quality, permissions and recovery behavior.
Simple enough for the requirements
A minimal design still has to satisfy the problem. Leaving out a necessary boundary is incompleteness, not simplicity.
Some problems genuinely require complex solutions. A multi-agent code review process makes sense when the domain is complex enough that a single reviewer misses edge cases. A spec-driven development workflow makes sense when the project has real requirements that need to be tracked.
The KISS principle does not mean "make everything trivial." It means do not add complexity beyond what the problem demands. Build the minimal system that solves the actual problem. Not the system that solves all hypothetical future problems. Not the system that looks impressive in a blog post. The system that works.
Choose understandable boundaries
Prefer clear ownership, small interfaces and visible state. These make a workflow easier to reason about when an operation fails.
Identify the edge cases that matter for correctness and recovery. The diagram’s size is less important than whether the system behaves acceptably under those conditions.
Compare complete outcomes and maintenance effort before declaring one workflow more productive. A single file and a multi-agent system can each fit different requirements.
Keep the components that earn their place, and make their responsibilities clear. Revisit the design when evidence or requirements change.
