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

Annotations already declare readOnlyHint=true, idempotentHint=true, and openWorldHint=false, so the safety profile is covered. The description adds essentially no behavioral context beyond the schema enum: it does not say what form the doctrine comes back in, whether listing vs. fetching differs, or how much content to expect.

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 framing ('How to build here') front-loaded and the content categories enumerated after. Nothing is redundant or padded.

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?

There is no output schema, so the description could usefully describe the return shape or volume, and it does not. Parameters are well covered via schema and annotations cover safety, but an agent still cannot tell what a doctrine response looks like.

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 both parameters (topic and optional name) are already fully documented in the schema, giving a baseline of 3. The description adds no syntax or format detail beyond the schema.

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 names a specific verb-resource pairing (get doctrine) and enumerates the content categories it returns: Ubuntu pillars/principles, mzizi conventions, and AI instruction sets, which map cleanly to the topic enum. It does not, however, explicitly distinguish itself from close siblings like mzizi_get_architecture or mzizi_get_skills, so an agent must infer the boundary.

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?

'How to build here' implies the usage context (fetch project doctrine when you need build guidance), but there is no explicit when-to-use, when-not-to-use, or named alternative among the many sibling getters. Guidance is implied rather than stated.

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