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. The word "ordered" hints at positional semantics, but the description does not say whether the new section appends at the end, whether ordering can be controlled, what permissions are required, or whether the operation is idempotent. Substantial gaps for a mutation tool with zero annotation coverage.

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 efficient sentence with no waste and the core action front-loaded. It is terse to the point of under-specification rather than padded, so it earns credit for structure but not a top mark.

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?

Output schema exists, so return values need not be explained, and 100% schema coverage handles parameters. However, for an unannotated mutation tool, the description omits ordering behavior, permissions, and prerequisites, leaving it only minimally adequate.

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 name, project_id, and agent are already documented in the schema. The description adds only the word "ordered" beyond the schema, contributing no syntax or format detail. Baseline 3 applies 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?

Clear verb + resource + scope: "Add an ordered section to a project." An agent can distinguish this from project_section_list (which reads) by the verb, though the description never names that sibling explicitly. Purpose is unambiguous but lacks explicit sibling differentiation.

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?

No when-to-use guidance, no prerequisites (e.g., project must exist / caller must be a member), and no mention of the sibling project_section_list or where a new section is placed. The agent is left to infer all usage context.

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