toggle_debug_render

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

Annotations declare readOnlyHint=false, so the agent knows this mutates state, and 'toggle' is consistent with that. Beyond that, the description adds nothing: it doesn't say whether the mode is per-session or persisted, what the resulting state is, or that toggling requires a prior debug render session. With a toggle (inherently non-idempotent) and no idempotent/destructive hints, this is a meaningful gap.

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?

One short, front-loaded sentence with no filler or redundancy. It is not padded, though it is arguably terse to the point of under-specification rather than maximally efficient communication.

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 output schema, only a single readOnlyHint annotation, and one parameter, the description carries most of the burden and delivers very little. It omits the effect of the toggle, its persistence, the resulting state, and how it interacts with the debug_function/run_function family.

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 coverage is 100% for the single cms_file_id parameter, so the schema already documents it. The description's 'for a CMS file' merely restates the parameter's target without adding format, source, or lookup semantics. Baseline 3 is correct when the schema does the heavy lifting.

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 gives a concrete verb (toggle) and resource (debug render mode for a CMS file), so the basic action is identifiable. However, 'debug render mode' is unexplained jargon, and nothing distinguishes it from the many debug/function siblings (debug_function, run_function, update_cms_file). It states what but not what it means in practice.

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?

There is no guidance on when to use this tool, when not to, or how it relates to alternatives like debug_function or update_cms_file. The only implied context is that a CMS file must exist. An agent must guess at the use case and any prerequisites.

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