profile.batch

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

With no annotations at all, the description carries the full behavioral burden and mostly drops it. It discloses that the operation is multiplexed over many profiles, which is useful, but says nothing about the irreversibility of 'delete', partial-failure/atomicity behavior when some profiles fail, permission requirements, or rate limits — all critical for a bulk mutation tool.

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?

A single sentence, front-loaded with the action verbs and closed by the scope modifier. Nothing is redundant and nothing is padded; every word does work.

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?

For a high-blast-radius bulk mutation tool with no annotations, no output schema, and an empty input schema, the description is far too thin. It omits failure semantics, delete irreversibility, and the mechanism for specifying target profiles, leaving the agent unable to invoke the tool correctly from the definition alone.

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?

The input schema declares zero parameters, so the baseline is 4. The description compensates somewhat by enumerating the valid operations (start, stop, delete, reassign) and targets (proxy, extensions), which is genuinely semantic content an empty schema lacks — but it gives no clue how individual profiles are addressed in a batch call.

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?

Names four concrete operations (start, stop, delete, reassign) on a named resource (profiles), with the scope modifier 'across many profiles' that separates it from the sibling single-profile tools profile.start, profile.stop, and profile.update. It is clear what the tool does, though it never names those siblings directly, so differentiation is inferred rather than stated.

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?

'Across many profiles' implies this is the bulk alternative to profile.start/profile.stop/profile.create, but the description never says so explicitly and gives no when-not condition or prerequisite. The context is strong enough for an agent to infer bulk-vs-single usage, but it is left to inference.

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