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

Annotations already declare readOnlyHint=false, idempotentHint=false, openWorldHint=true, and destructiveHint=false, so the safety profile is partly covered. The description adds nothing about what happens on duplicate registration (important given idempotentHint=false), required authorization, or side effects on the org directory. For a non-idempotent mutation, that is a meaningful gap.

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 with no filler. It is efficient, though its brevity is achieved partly by omitting necessary detail rather than by tight wording.

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 six-parameter, non-idempotent mutation with no output schema and zero schema description coverage, the description is far too thin. It does not explain required fields, conflict behavior, or what a successful registration produces.

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% across six parameters. The description alludes to org, cells, and owners but says nothing about the required url, optional name, or team, and provides no format or constraint details. It fails to compensate for the undocumented 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 verb phrase 'Put a repo in the org's directory' conveys a registration action against a specific resource, and it gestures at cells/owners as associated data. However 'put' is vague versus a precise verb like 'register', and 'cells' is unexplained jargon. It does not differentiate the tool from siblings such as repo_list or repo_search.

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 repo_list, repo_search, source_repos, or org/directory tools. No prerequisites (e.g., org membership, existing repo URL) and no exclusions are stated, leaving the agent to infer placement.

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