Your AI Agent Is Reading More Than Your Code

Summary

AI agents interpret more than just code, including file names, descriptions, comments, and documentation, which directly influences their operational behavior. Traditional software naming conventions, such as `OldPaymentService` or `experimental-refactor-helper`, often carry historical context understood by human developers but can mislead AI agents, causing them to ignore tools or choose suboptimal workflows. This phenomenon can lead to subtle "hallucinations" where agents misinterpret project context. The article advocates for designing an agent's information environment, similar to software design, by providing clear, operational instructions in files like `CLAUDE.md` or `AGENTS.md`. These files should contain specific rules (e.g., "Use `pnpm`, not `npm`") and avoid vague advice or excessive detail, focusing on job-oriented naming for skills and agents (e.g., `review-pr-diff`) to prevent "context debt."

Key takeaway

For AI Engineers designing agentic systems, your naming conventions and documentation directly influence agent behavior. Avoid using status-based names like "experimental" or "legacy" for skills and files; these can mislead agents into incorrect actions. Instead, name components by their job function. Maintain concise, operational instruction files (e.g., `CLAUDE.md`) with specific rules. Regularly test agents with real-world, messy prompts to validate context design and prevent "context debt."

Key insights

AI agents interpret all textual context, making naming and documentation critical for correct behavior.

Principles

• Agent behavior is directly affected by naming.
• Context design is as critical as software design.
• Avoid status-based naming for agent skills.

Method

The article proposes designing an agent's information environment by creating focused `CLAUDE.md` or `AGENTS.md` files with specific operational rules, architecture boundaries, common commands, repeated mistakes, high-risk areas, and decision rules.

In practice

• Name agent skills by their job function.
• Keep agent instruction files concise, operational.
• Test agents with messy, real-world prompts.

Topics

• AI Agents
• Agentic Engineering
