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

Annotations already cover safety (readOnly, idempotent, non-destructive, closed-world), so the bar is lower; the description still adds two useful facts: it returns ALL links with no filtering, and links are directional (parent→child), which matters when interpreting the graph. Missing pagination/volume expectations keeps it from a 5.

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?

One sentence, front-loaded with the verb and resource, with the parenthetical and scope clause each carrying real information. No waste.

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 zero-parameter list tool with a full annotation set and no output schema, the description covers what is needed to select and call it. It could add a note on return volume or ordering, but no output schema means nothing critical is omitted.

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?

The tool takes zero parameters, so the baseline is 4; the description correctly implies there are no filter arguments by scoping results to the active workspace.

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 task dependencies) and clarifies the data's shape as parent→child links scoped to the active workspace. It doesn't explicitly name how it differs from create_task_dependency / delete_task_dependency / clear_task_dependencies, but the read-only, all-encompassing framing makes the distinction obvious.

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 only implied: an agent can infer this is the tool to enumerate dependency links before mutating them, and 'in the active workspace' signals there is no project/task filter argument. There is no explicit when-to-use or when-not-to-use statement and no alternative named.

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