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

Annotations already flag destructiveHint=true and non-idempotent, so the safety bar is lower. The description adds genuinely new context: the wallet gets bound, the money involved is devnet test funds rather than real value, and a human confirmation step is expected. It still omits what happens to a previously claimed milestone or what a failed claim 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?

A single tight sentence with the core action front-loaded and no filler. The phrasing 'binds the wallet it pays in devnet test money' is slightly compressed to the point of ambiguity about who pays whom.

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 destructive, non-idempotent mutation with no output schema and four undocumented parameters. The description does not cover prerequisites (sign-in/session), what claiming changes, or the consequence of a duplicate claim, which is significant for an irreversible operation.

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 0% across four parameters, so the description must compensate. Only 'wallet' gets any meaning ('binds the wallet it pays in devnet test money'); project, milestone, and especially session are entirely unexplained in both schema and text.

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 ('Claims a milestone') plus the actor role ('as its maker') and an effect ('binds the wallet'). It is distinguishable from knos_milestone_submit and knos_milestones, though it never explicitly contrasts with them.

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?

Gives one concrete prerequisite ('ask your human first'), which is real when-to-use guidance for a destructive action. It does not say when to prefer this over knos_milestone_submit or what state a milestone must be in to be claimable.

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