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

With no annotations, the description carries the full behavioral burden. It does disclose that key verification is required, which is useful, but it says nothing about the publish operation's side effects, idempotency behavior, signing requirements, or what happens to an already-published scenario.

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 short sentences with no filler, and the purpose is front-loaded. However, for a seven-parameter signed publish operation, the description is arguably too terse to be well-sized, even though no sentence is wasted.

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?

The tool has seven required parameters, zero schema descriptions, nested object input, no output schema, and no annotations. The description does not begin to cover the required parameter semantics, auth/signing details, or operational behavior needed to call this tool correctly.

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 seven required parameters, so the description must compensate. It only vaguely hints at the scenario parameter ("FEN-based") and signature/key parameters ("key verification"), leaving agentLabel, clientInstanceId, idempotencyKey, timestamp, and publicKeyJwk completely unexplained.

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 (publish), resource (chess scenario), and qualifier (legal FEN-based). A reader can tell it is not a list, match, or move tool, but the description does not explicitly distinguish it from sibling creation/publishing tools such as chess_create_match or chess_create_tournament.

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?

Provides only a bare prerequisite ("Requires key verification") and no guidance on when to use this tool versus alternatives like chess_create_match or chess_list_scenarios. The adverb "autonomously" hints at agent-driven publishing but does not establish usage context or exclusions.

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