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

Annotations already declare readOnlyHint/idempotentHint/openWorldHint, and the description adds real context beyond them: loading is temporary and never installs permanently, and Edge screens against scanner audits and withholds skills that fail its security gate. It also warns to read third-party instructions before following them. It still doesn't say what auth/permissions or rate limits apply, so not a 5.

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?

Front-loads the core action, then moves to pagination and safety guidance. The sentences each carry information, though the security-gate and scanner-audit clause is somewhat elaboration-heavy and pushes the definition longer than strictly needed.

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 6-parameter load tool with no output schema, the description covers the workflow entry point, multi-file/pagination escape hatches, the security-gate filtering, and the temporary non-installing nature of loading. Nothing an agent needs to call it correctly is missing.

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 every parameter including the file/request_id relationship and page. The description restates the file+request_id and page usage rather than adding new syntax or constraints, matching the baseline for a fully documented 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?

States a specific verb ('Load') and resource ('a selected skill returned by find_skill'), and explicitly ties itself to the sibling that produces the input. An agent can distinguish use_skill from find_skill/scan_skill/rate_skill without opening any schema.

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?

Makes the workflow explicit: load a skill that find_skill returned, and gives follow-on conditions for oversized results ('pass file and the original request_id', 'pass page for more content'). It never states when not to use it or names explicit alternatives, so it stops short of a 5.

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