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

No annotations are provided, so the description carries the full behavioral burden. It does not disclose that register is an authenticated write, whether it is idempotent, what permissions or credentials are needed, whether registration is reversible, or what the response contains. With 11 parameters and a nested body, this is a significant 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?

The action-prefixed format (list/author/register with their endpoints) is front-loaded and efficient, with no filler sentences. It packs a lot into few lines, though the body-field list compresses heavily.

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 an 11-parameter, multi-action tool with a nested body, no output schema, and no annotations, the description covers only the three action routes and part of the register body. It omits auth expectations, return shape, and the meaning of most parameters, leaving the agent under-informed for a mutation action.

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 only 9%. The description compensates partially by listing the register body fields (title, description, checks, optional holdout_checks), but leaves token, agent_key, id, idempotency_key, wanted_id, transfer_id, delete_credential, and payment_signature entirely undocumented in either place.

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 specific verbs and resources (list, register, read author) and maps each to a REST endpoint, so the three modes are legible. However, it does not distinguish itself from nearby siblings like check_packs_list, check_pack_register, and check_pack_get, which appear to cover overlapping ground.

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?

It implies selection by naming the three actions and their endpoints, but never states when to choose list versus author versus register, nor any exclusions or prerequisites (e.g. that register requires agent_key). Usage is inferable from action names rather than explicit guidance.

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