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

With readOnlyHint, idempotentHint, and destructiveHint already covering the safety profile, the description adds real value by disclosing ordering (most recent first) and the shape of each result, including the recoverable access code and recipients. That access-code disclosure is security-relevant context an agent could not get from annotations alone. The 'does not modify pages' sentence is largely redundant.

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?

Three short sentences, front-loaded with purpose, scope, and ordering before the optional filter and return shape. The closing 'Does not modify pages' duplicates readOnlyHint and does not earn 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?

For a one-optional-param read tool with no output schema, the definition is nearly complete: it explains ordering, filtering, and returned fields. It omits any statement about result size or limiting behavior for a workspace-wide listing, which matters since no pagination parameters exist.

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% and the single parameter is self-documenting, so 3 is the baseline. The description restates the filter as optional, which is mildly useful, but adds no format or matching semantics for the project value.

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 links) plus scope (published, authenticated workspace) and ordering (most recent first). An agent can distinguish it from get_page or link_report, though the overlapping find_link sibling is never addressed.

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?

'Optionally filtered by project' implies the intended usage pattern, but there is no explicit when-to-use, when-not-to-use, or alternative such as find_link for targeted lookups. Usage is inferable rather than stated.

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