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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so safety is covered. The description usefully adds the default page size (take = 10, newest first) and the difference in payload shape between list and detail mode, which annotations do not carry. It stops short of stating ordering guarantees beyond 'newest' or how much data the full mode returns.

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?

Two compact sentences, front-loaded with the default behavior and followed by the id override. Dense with domain terms but no filler or repetition.

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 takes on return-value disclosure and does list what the detail mode includes (milestones, held orders, AMC commitments, attempts, purchase locations) plus what the list mode summarizes. That is adequate for a two-parameter read tool, though the jargon leaves some uncertainty about field contents.

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 0%, so the description must carry the semantics, and it does explain the two parameters meaningfully: 'take' defaults to 10 and 'id' switches to full single-project detail. It omits the 1-100 bound (present in schema) and doesn't say what happens when an id is unknown, but the core meaning of both params is supplied.

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 does convey a dual-mode read of projects (list vs. single-by-id) and mentions milestones, which the title already implies. But the value claims are expressed in unexplained domain jargon ('held units', 'tranches', 'AMC commitments', 'where the work can be bought'), so an agent gets the shape of the tool without a clear sense of what the data means. It also never states how it differs from siblings like knos_milestones or knos_project_open.

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?

'With id: one project in full' vs. default list mode implies the usage pattern, which is more than nothing. There is no explicit when-to-use/when-not guidance and no mention of the closely related sibling tools, so the choice between this and knos_milestones/knos_project_open is left to inference.

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