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

No annotations are provided, so the description must carry the full behavioral burden. It usefully discloses that unsigned sets are rejected and that the index is a non-canonical cache, but it omits important mutation behaviors such as idempotency, overwrite semantics, authentication requirements, rate limits, and the response shape on success.

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 concise sentences with the action front-loaded and no wasted text. The signature rationale and cache/canonical distinction are both tightly expressed.

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?

There is no output schema and no annotation coverage, so the description should ideally explain what a successful publish returns or what error states exist beyond unsigned-set rejection. It covers the canonical-versus-cache distinction well but leaves the mutation’s result and operational preconditions underspecified.

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 100% for the single demand_set parameter, which already documents that it must include publisher, signature, and demands[]. The description adds the spec reference (A.3) and emphasizes the signature requirement, but it does not add meaningful detail about the nested object beyond what the schema provides. Baseline 3 is appropriate.

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 (Push) and resource (signed demand_set document, spec A.3) into the index. The description also distinguishes this operation from the canonical domain file, making clear what the tool does and how its result relates to other representations.

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?

The description implies usage by explaining that unsigned sets are rejected and that the domain's well-known file remains canonical. However, it does not explicitly say when to choose this tool versus alternatives such as get_demand, nor does it state preconditions or exclusions beyond the signature requirement.

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