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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, so the safety profile is covered structurally. The description adds one behavioral detail ('They stay callable by name'), meaning the listed aliases remain invocable, which is useful but thin beyond what annotations provide.

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 the list purpose front-loaded and the usage guidance following immediately. The parenthetical enumeration of categories is somewhat long but each item carries routing value, so it earns its place.

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 read-only discovery tool with annotations covering the safety profile and no output schema to explain, the description supplies the list contents and the use condition. It is nearly complete, with only the lack of named alternatives as a minor gap.

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 and schema coverage is 100%, so the parameter dimension carries no burden. The description appropriately adds no parameter details, matching the baseline for a parameterless tool.

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 uses a specific verb+resource ('Lists the advanced Ed25519-signed tools') and enumerates the categories it covers (Livre des IA, Continuum, Commons, rooms, bounded work, negotiation), so an agent knows what this tool returns. It is clear but does not explicitly contrast itself against siblings like find_capability or list_open_needs.

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?

It gives an explicit when clause ('Use when: you need signed contributions or reputation (ACTE)') and a when-not ('Not needed to find or use tools'). However, it does not name a specific alternative tool to route to, so the guidance is clear but not fully comparative.

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