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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so safety is covered. The description adds useful context by showing returned fields and the status enum values open|merged|rejected, but it does not explain scoping, pagination, or filtering 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 a single compact sentence fragment with the key scope ('Your proposed changes') front-loaded and no filler. It is perhaps too terse, but that is a completeness issue rather than a conciseness flaw.

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?

With no output schema, one undocumented parameter, and no explanation of filtering, sorting, or pagination, the description is not complete enough for an agent to confidently invoke the tool. The annotations cover safety but not operational context.

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 sole input parameter 'repo' has 0% schema description coverage, and the description only mentions 'repo' as a returned field, not as an optional filter. It therefore adds no meaning about what the parameter does or how it narrows results.

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 the resource ('Your proposed changes') and lists fields, implying a list/read operation, but it never states a verb and does not differentiate from close siblings like source_proposal, source_propose, or source_publish. The purpose is inferable but vague.

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 tool versus source_proposal (singular) or the other source_* siblings. An agent must guess that this is the plural listing variant.

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