cache_content

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are supplied, so the description carries the full behavioral burden. It hints at persistence via 'for future use' but never says where the cached content goes, whether it survives the session, how it is later retrieved, or whether it overwrites prior cache entries.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The functional sentence is short and front-loaded after the bracketed environment note. The bracket is shared boilerplate rather than this tool's content, but it does not obscure the action.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no annotations and no output schema, the description should explain the caching lifecycle but stops at 'for future use'. For a low-risk utility that is minimally viable, though an agent still cannot tell how cached content is consumed downstream.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both parameters (intent, content) are already documented; the baseline is 3. The phrase 'what you have found so far from the current page' adds modest context for what 'content' should hold, but no format or size expectations.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and object — caching content found on the current page for later use — which is clear enough to act on. It does not, however, distinguish this tool from nearby siblings like read_page or run_recipe, so the agent must infer the boundary itself.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The only guidance given is the shared bracketed boilerplate ('use only when the task requires acting on a real website'), which applies to the whole browser toolset, not to caching. There is no statement of when to cache versus when to read, act, or finish, and no prerequisites or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
