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

With no annotations, the description carries the full burden and does disclose two useful behavioral facts: an API key is required and results are scoped to one connected account. It also characterizes return content (PRs, issues, docs, threads). It says nothing about pagination, empty results, or permissions on the task, which leaves meaningful gaps for a bare read tool.

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 sentence that front-loads the resource and keeps the auth prerequisite in parentheses. The odd capitalization of 'ACCOUNT' is a minor blemish, but nothing is padded.

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?

This is a simple one-parameter read tool with no output schema, and the description covers what is returned, which account it reads from, and the auth requirement. Only return-shape details like pagination or ordering are absent, which is acceptable at this complexity.

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?

There is only one parameter and schema description coverage is 100%, with the schema already telling the agent to get taskId from list_tasks. The description reinforces the single-task scoping ('one task'), which is enough for a one-parameter tool.

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 (links) scoped to exactly one task, and enumerates the kinds of things a link can point at (PRs, issues, docs, threads). It lacks an explicit verb like 'list' and never mentions the sibling find_by_link, so the agent must infer the distinction, but the resource and scope are unambiguous.

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?

There is no when-to-use guidance, no exclusion of alternatives, and no mention of the closely related find_by_link tool. The only contextual hint is that it operates on a single task, which implicitly requires taskId rather than a search query.

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