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

With no annotations, the description carries the full behavioral burden. It usefully discloses that the deletion is 'soft' (i.e., not permanent) and covers 'all active versions', which is meaningful context. But it says nothing about reversibility/restoration, required permissions, or what happens to dependent references, leaving notable gaps for a destructive-ish operation.

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 zero waste. The verb and scope lead the sentence so an agent can triage it at a glance.

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?

Return values are covered by the output schema and params are fully documented, but as a mutation tool with no annotations it omits prerequisites, reversibility, and sibling routing. For a skill-forget operation surrounded by many memory_* siblings, more context would help.

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 are already documented in the schema. The phrase 'by name' reinforces the name parameter but adds no syntax or format detail beyond what the schema provides. Baseline 3 applies when the schema does the heavy lifting.

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 (soft-delete), resource (skill), and scope (all active versions, by name). An agent can grasp the operation quickly. However, it offers no differentiation from close siblings like memory_forget or memory_forget_procedure, leaving the agent to 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?

There is no when-to-use guidance and no named alternative. The agent is not told when to forget a skill versus using memory_forget, memory_forget_procedure, or memory_skill_set to modify it. Usage must be inferred entirely.

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