set_segment_permissions

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. The description indicates this is a write operation (changing permissions), but it does not state whether permissions can be revoked, the scope of the change (persistent across sessions?), or error conditions (e.g., what happens if the address is invalid). It provides basic behavior but lacks depth.

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 a single, short sentence that front-loads the action and resource. Every word serves a purpose, with no fluff. It is efficiently structured for an AI agent to quickly parse, though it could benefit from a brief note on defaults.

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 tool's complexity (4 parameters, 1 required, no enums, no schema description coverage, but an output schema exists), the description is minimally adequate. The output schema likely documents return values, so that gap is filled. However, the description does not address edge cases (e.g., segment not found) or the order of operations (e.g., can all permissions be removed?). It is complete enough for common use cases but lacks depth.

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 compensate. The description mentions 'read/write/execute permissions' which maps to the boolean parameters 'read', 'write', and 'execute', adding some semantic context. However, it does not explain the 'address' parameter format or the effect of boolean defaults (all true implies at least one should be false to change). The description adds marginal value over the schema but does not fully clarify parameter roles.

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 the action ('Change'), the target resource ('the segment containing the given address'), and what permissions are affected ('read/write/execute'). It distinguishes itself from sibling tools like 'list_segments' (which lists segments) and 'create_segment' (which creates segments), making the purpose unambiguous.

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?

The description provides no guidance on when to use this tool versus alternatives. For example, it doesn't mention that changes affect segment-level permissions system-wide, or that other tools like 'patch_bytes' or 'make_data' might be more appropriate for specific use cases. No exclusions or prerequisites are stated.

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