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

Annotations already declare destructiveHint=true and idempotentHint=false, so safety is covered structurally. The description adds genuinely useful context by stating expectedVersion must be the current revision, revealing an optimistic-concurrency precondition, but it never says whether the delete is hard or soft, or how a version conflict surfaces.

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 tight sentence with the action and its key precondition front-loaded; nothing is redundant.

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 destructive, non-idempotent mutation with no output schema and six parameters, the description covers the versioning rule but omits conflict/error behavior and path semantics, leaving an agent slightly under-informed.

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 coverage is 50%, and the description usefully explains the most consequential parameter, expectedVersion (current revision), which the schema leaves bare. However id, path, and the idempotency/operation distinction get no added meaning, leaving part of the gap unaddressed.

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 (Delete) plus resource (a skill by id) and names the workspace scope. Siblings like pathrule_delete_memory and pathrule_delete_rule make the resource distinction evident, though the description itself doesn't explicitly contrast them.

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?

Usage is implied by the destructive verb and the naming convention, but there is no explicit guidance on when to delete versus calling pathrule_update_skill or pathrule_history_skill, nor any stated prerequisites.

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