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

Annotations cover the safety profile (not read-only, open-world, not destructive), and the description adds genuinely useful context beyond them: the confirmation-by-default behavior, the ability to switch it off, the user-confirmation requirement for outward-facing effects, and the API-key access prerequisite. The tier-takeover mechanics and the 'response lists all tiers in order' note also disclose effects an agent can't see in schema.

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 core content is front-loaded, but the description is repetitive: the allocation/pass allocation and time/pass time distinction is stated twice (in the first two sentences and again in the third). The confusing 'Add a release' opener costs clarity for no benefit. Several sentences restate the same mechanic.

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 mutation tool with no output schema, the description covers the key gaps an agent needs: what the tier does, that price is in cents, the confirmation/auth requirements, and the shape of the response (all tiers in order). It is close to complete, missing only the relationship to the sibling ticket-type tools.

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%, so all five parameters are already documented. The description restates 'Price is in cents,' which duplicates the schema's 'Face value in cents,' and adds no format, dependency, or constraint detail for name/time/allocation beyond what the schema provides. Baseline 3 is appropriate.

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?

States the verb+resource clearly with 'Adds a price tier to a ticket type' and explains the tier's role (takes over after an earlier tier's allocation sells out or at a set time). However, the opening sentence 'Add a release to a ticket type...' is muddled and reads like leakage from a different tool, which slightly clouds the purpose. It does not explicitly contrast with dice_add_ticket_type or dice_update_ticket_type.

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?

Gives real operational context: default confirmation per call, the option to disable it, the need to confirm with the user because it reaches other people, and the API-key requirement. But it never states when to use this versus the sibling ticket-type tools, which is the primary selection question. Usage is implied rather than differentiated.

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