Identity vs. Capability: Why Your Agent Strategy Needs More Than a Default File
The Two Bets of the Agentic Web
The agentic web is splitting into two distinct paths: identity and capability. Most websites are currently sleepwalking into an 'identity' strategy because a plugin decided it for them.
Identity is about telling an AI who you are and what your content covers. Capability is about giving an agent the tools to actually complete a task on your site—like searching inventory, checking prices, or booking a service.
Before you assume your site is ready for the future, you need to understand the difference between a brochure and a cash register. For a deeper look at how your site identifies itself, check out our guide on LLMs.txt.
The Identity Bet: A Passive Hedge
The identity layer is represented by llms.txt. It is a simple markdown file at your root directory designed to provide a clean index for AI models.
The practical route is simple: if you have an llms.txt file, check it. Many WordPress plugins have enabled this by default, often populating it with generic or outdated data you never reviewed.
Do not export everything and call it an audit. If you are going to host an identity file, it must be generated from your own source of truth—the same data that powers your site. If it drifts out of sync, it is worse than having no file at all. Currently, there is no hard evidence that major AI systems rely on this file for ranking, so treat it as a low-effort hedge, not a core strategy.
The Capability Bet: Moving Beyond the Brochure
If identity is a signpost, capability is the door. This is where the industry is heading. Through standards like WebMCP, you can expose callable tools that allow agents to interact with your site’s backend functions directly.
Instead of an agent guessing how to navigate your UI, your site tells it: 'Here are the inputs I need, and here is the structured data I will return.' This is a small task with high leverage. By implementing these tools, you move from hoping an agent reads your content to ensuring an agent can complete a transaction on your behalf. This is the difference between a passive visitor and a functional integration.
Prioritising Your Technical Effort
When deciding where to put your engineering hours, prioritise by crawl impact, indexation impact, and commercial value.
- Audit your current state: Check for an existing
llms.txt. If it exists, verify its accuracy. If it is wrong, delete it or fix the generation process. - Assess your commercial goals: Does your site require user interaction? If you handle bookings, inventory, or complex filtering, the capability layer is where your ROI lies.
- Build for the future: If your site is purely informational, focus on clean, server-rendered HTML. A crawl is evidence, not the whole truth, but clean code remains the foundation for any AI agent to parse your site successfully.
Conclusion
The agentic web is not about being read; it is about being useful. While the industry is currently obsessed with identity files, the real winners will be those who build functional, machine-readable interfaces. By focusing on the AI decision layer, you ensure that your site is not just a destination for bots, but a functional tool for the next generation of web agents.
