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

With no annotations provided, the description carries full behavioral disclosure. It reveals idempotency (returns existing token/slug), the eager push of latest rendered HTML to the Railway bucket, the dual URL scheme with slug and token, and the seat-based access restriction. These are meaningful behavioral traits beyond 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?

The description is information-dense without fluff; every sentence contributes either purpose, idempotency, output URL structure, or access guidance. The main action is front-loaded, and supporting details are grouped logically. It is longer than a two-sentence description but earns each sentence.

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?

For a single-parameter tool with an output schema and no annotations, the description covers everything needed to invoke it correctly: what it does, return behavior, URL formats, idempotency, and authorization restrictions. An agent can confidently decide whether to call this tool or request approval.

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 100% and the only parameter, file_id, is already described as 'File UUID to publish.' The description adds surrounding context about URL generation and idempotency but does not add new file_id-specific semantics. Baseline 3 is appropriate because the schema fully documents the parameter.

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 opens with a specific verb and resource: 'Publish a shared file: generate the public share token + slug and URL.' It clearly differentiates file_publish from siblings like file_unpublish and file_update. The scope is unambiguous and an agent can tell exactly what operation this invokes.

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 gives explicit routing guidance: agent seats are refused and should call request_gated_approval(gate="publish") instead, while console humans may still publish directly. It also notes idempotency, so agents know re-calling is safe. This goes beyond a simple 'use for publishing' statement.

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