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

Annotations already declare readOnlyHint and openWorldHint=false, covering the safety profile. The description adds domain-specific lifecycle semantics for statuses (e.g., 'adopted' possibly revised, 'revised' re-proposed), which is useful context beyond annotations, but it doesn't cover pagination, ordering, or return behavior.

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 front-loaded with the core purpose and then details status semantics in a single dense paragraph. It is appropriately sized and free of fluff, though slightly better structure could improve readability.

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 simple read-only list tool with one optional enum parameter and no output schema, the description covers the default and most status meanings. However, missing enum values ('amended', 'repealed') and absent usage context leave gaps for an agent to fully understand the tool's behavior.

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%, so the description must carry the full burden. It explains five of the seven enum values (open, adopted, revised, rejected, all) but omits 'amended' and 'repealed'. It also references a 'revised_as' field not present in the schema. Partial compensation warrants a 3.

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 clearly states a list operation over 'discussions (proposed rules)', giving a specific verb and resource. It doesn't explicitly differentiate itself from siblings like read_discussion or get_charter, but the verb/resource combination is unambiguous.

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 offers no guidance on when to use this tool versus alternatives such as read_discussion. It only explains status meanings, leaving the agent to infer usage context.

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