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

No annotations are provided, so the description carries the full behavioral burden. It hints at versioning ('a new version') but never says what happens to the prior version, whether the statement is written directly or held as a draft awaiting approval, or what permissions are required for this mutation.

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 short sentence with the resource front-loaded and no filler. It is efficient, though its brevity is part of the reason other dimensions are under-served.

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?

An output schema exists, so return values need not be explained, and the parameter surface is fully documented. Still, for a mutation tool with no annotations, the critical ambiguity of 'propose' versus 'set' (draft vs committed) is left unresolved for the agent.

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 100%, so the schema already documents kind, agent, and content_md; the baseline is 3. The description's 'vision, mission, or purpose' merely echoes the enum values and adds no format or constraint detail beyond what the schema supplies.

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 (propose/set) and resource (vision, mission, purpose), which maps directly to the kind enum. However, it does not differentiate itself from adjacent strategic siblings like memory_strategic_plan_set or memory_strategic_objective_set, and the verb 'propose' sits awkwardly against the tool name 'set', leaving the exact effect slightly unclear.

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?

There is no guidance on when to use this versus memory_strategic_statement_get or the other strategic setters. No prerequisites, no mention of whether the proposal is committed immediately or awaits review.

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