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

Annotations already declare destructiveHint=true and idempotentHint=false, so the safety profile is carried by structured data. The description adds the useful scope note that all revision states are editable, but does not disclose consequences (e.g., that null clears a field) or confirm reversibility. Adequate with annotations doing most of the work.

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?

Two tight sentences with no filler, and the core action is front-loaded before the scope qualifier. Every clause earns its place.

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 3-parameter mutation with full schema coverage, no output schema, and annotations covering the safety profile, the description is close to sufficient. It would be fully complete with a note on whether edits apply immediately or require a promote/publish step.

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 the id, the optional name, and the optional description including the "pass null to clear" behavior. The description adds no parameter-level meaning beyond the schema, so the baseline of 3 applies.

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 and resource: renaming or changing the description of a skill revision. This is unambiguous and distinguishable from createSkillRevision, deleteSkillRevision, and updateSkillRevisionFile. It does not explicitly name a sibling to route against, so it stops short of a 5.

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?

"Works for drafts, the active revision, and historic revisions" gives useful scope on which revisions can be targeted, which is real guidance. However, it does not say when to use this versus alternatives such as updateSkillRevisionFile or promoteSkillRevision, so usage is only implied.

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