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

Annotations already declare read-only, idempotent, non-destructive behavior, so the description's added value is the required API-key scope `sprints:read` and the shape of the returned DTO — both are genuine context an agent needs before calling. Missing only detail on error behavior for unknown identifiers.

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 with the operation front-loaded and no filler. 'SprintDTO' is internal type jargon that adds little for an agent, but the text is otherwise tight and well-ordered.

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?

With no output schema, the description naming SprintDTO and task statistics is helpful but leaves the actual fields unenumerated, and it never specifies the identifier format or failure mode for a missing sprint. Adequate for a simple single-entity read, but with clear gaps.

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 67%: `account` and `workspace` are well documented inline, but `sprintIdentifier` has no schema description at all. The description contributes only 'by identifier' and does not clarify whether that means a numeric ID, key, or exact name, leaving the one undocumented parameter ambiguous.

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 ('Fetch a sprint by identifier') and names the return payload with its salient content ('SprintDTO with task statistics'). It does not differentiate itself from the closely related pm_get_sprint_tasks and pm_get_sprint_burndown, which an agent could easily confuse for this.

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 explicit guidance on when to call this versus the sprint siblings: pm_get_sprint_tasks exist to list tasks and pm_get_sprint_burndown returns burndown. The single-sprint-entity reading is inferable from 'by identifier', but nothing states prerequisites or exclusion conditions.

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