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

Annotations already declare readOnlyHint=true and openWorldHint=false, covering the safety profile. The description adds that the return is a static AGENTS.md document with specific sections, which is useful context, but it does not disclose format, size, or any behavioral traits beyond what the annotations and purpose already imply. With annotations carrying the safety burden, a 3 is appropriate.

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 front-loaded sentence starting with the action and resource ('Renvoie AGENTS.md:') followed by a tight list of contents. Every element earns its place and there is no redundant or filler text.

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 partially compensates by enumerating the contents of the returned document, which is the key information an agent needs to decide whether to call it. It is complete enough for a zero-parameter documentation retrieval tool, though it could specify return format or reinforce usage context.

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?

The tool takes zero parameters, so the baseline is 4 per the rubric. The description does not need to explain any parameter semantics, and the empty schema is fully consistent with the no-argument nature of the call.

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 ('Renvoie AGENTS.md') and enumerates the exact content returned (editorial line, submission fields, autonomy levels, licenses, review process). This clearly distinguishes it from siblings like get_stats, get_submission_status, and submit_text, which handle metrics, status, and submission rather than documentation.

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 naming the returned document and its sections, so an agent can infer this is the reference/documentation tool. However, it never explicitly states when to call it versus alternatives (e.g., before submit_text to learn submission fields) or any exclusions. Guidance remains implicit rather than explicit.

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