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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so safety is fully covered. The description adds only that results are paginated, and says nothing about ordering, total counts, or what happens with out-of-range pages.

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?

Two short sentences with the resource scope front-loaded and no filler. The pagination sentence is close to redundant with the schema, so it is efficient but not maximally earning its place.

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?

A simple read-only list tool with full annotation coverage and complete schema docs, so the bar is low; still, nothing is said about default ordering, whether pagination metadata is returned, or how empty results appear. Adequate but with clear gaps for an agent assembling a call.

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% with descriptions for project_id, page, and per_page, so the schema carries the parameter semantics. The description's "for a project" and "supports pagination" merely restate what the schema already documents, adding no new detail such as 1-based indexing or max per_page.

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 a specific verb and resource (list changelog entries) plus the scoping dimension (per project), which is enough to pick it over get_entry. It does not, however, distinguish itself from get_public_entries or explain how it differs from that sibling's listing.

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?

"Supports pagination" is the only extra guidance; there is no when-to-use, no prerequisite (e.g. project must exist / token scope), and no mention of when to prefer get_public_entries or get_entry instead. The agent must infer the routing.

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