set_permissions

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

With no annotations, the description fully delegates behavior. It describes each parameter's effect, notes default for flash_erase, and implies session-level changes. Missing details on reversal or side effects, but adequate.

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 well-structured with bullet-like lines, but the parameter list is somewhat lengthy. The main purpose is front-loaded, and each sentence is informative.

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?

Given the 6 optional parameters, no schema descriptions, and no annotations, the description is fairly complete. It explains all parameters and mentions persistent config. Missing error handling but output schema exists.

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 0%, so the description must explain every parameter. It does so comprehensively, describing what each parameter controls and their implications (e.g., 'destructive; off by default').

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 clearly states 'Adjust safety permissions for this session', using a specific verb and resource. It distinguishes itself from sibling tools (which are about debugging operations) as a permission management tool.

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?

It explains that only provided args change and mentions persistent settings in a JSON file, giving context. However, it doesn't explicitly state alternatives or when not to use this tool.

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