list milestone sets

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered. The description adds a real behavioral constraint (results are limited to the authenticated freelancer's sets, and ids must come from this call rather than being invented), but it says nothing about the offset pagination behavior implied by the schema.

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 what the tool returns and followed immediately by the action the agent should take next. No filler or restatement of the title.

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?

Low-complexity read tool with an output schema, so return-value detail is unnecessary, and the description supplies the workflow linkage to read_milestone_set. Only the optional offset/pagination semantics are left unaddressed.

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 one parameter (offset) with 0% schema description coverage and the description never mentions pagination, page size, or how to advance through results. With the schema providing only a bare integer bound, the description fails to compensate for the documentation gap.

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 ... milestone sets") and narrows scope to the signed-in freelancer's own sets. It also implicitly distinguishes itself from the sibling read_milestone_set by framing this as the discovery step that produces the id read_milestone_set consumes.

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?

Explicitly routes the agent onward: "Use a returned id with read_milestone_set" and warns "Do not guess a set." That is clear when-to-use and when-not guidance, though it never states the inverse case (e.g., if you already have an id, skip this tool).

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