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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so the safety profile is covered. The description adds genuinely new context beyond annotations: the fields returned (recipe figures, rating, problems, notes, id, link), the newest-first ordering, and the account requirement.

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 dense sentence carries the resource, ordering, returned fields and identity fields, with a short second sentence stating the account prerequisite. Front-loaded with the resource and free of filler, though the first sentence is long.

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, the description usefully enumerates the returned fields, ordering and account requirement. Combined with the fully documented parameters, an agent has what it needs to call the tool; only explicit alternative-routing guidance is missing.

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 (limit, bake_type) are fully documented in the schema, including the default and max for limit and the enum for bake_type. The description's 'newest first' merely echoes the schema's ordering note and adds no syntax or format detail beyond it, so the baseline 3 applies.

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 names a specific resource (the baker's own bakes from their Loafy bake journal) and its scope, which separates it from book/search siblings and from get/update_bake. The listing verb is only implied by 'bakes ... newest first' rather than stated, so it falls just short of a clean verb+resource phrasing.

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?

Usage is implied: the 'own bakes' scope and 'newest first' ordering signal this is the personal-journal retrieval tool rather than a search or a single-record fetch. However, no sibling is named and no explicit when/when-not guidance is given, so an agent must infer the routing itself.

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