security-set-item-acl-by-id

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

With no annotations provided, the description carries full burden for behavioral disclosure. While 'Sets' implies a write/mutation operation, it doesn't describe important behavioral aspects: what permissions are needed to execute this, whether changes are reversible, if there are rate limits, what happens on success/failure, or how it interacts with existing ACLs. The description is minimal and lacks crucial operational context.

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, focused sentence with zero waste. It's appropriately sized for the tool's complexity and gets straight to the point without unnecessary elaboration. Every word serves a purpose in conveying the core functionality.

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 security mutation tool with 6 parameters, no annotations, and no output schema, the description is insufficient. It doesn't explain the tool's security implications, what 'setting' an ACL entry means (overwrite? merge?), error conditions, or return values. Given the complexity and lack of structured metadata, the description should provide more operational context to be complete.

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 83% (high), so the baseline is 3. The description doesn't add any parameter-specific information beyond what's already in the schema - it doesn't explain parameter relationships, provide examples beyond what's in enum descriptions, or clarify edge cases. It meets the minimum viable baseline but doesn't enhance understanding of the parameters.

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 ('Sets an access control entry') and target resource ('to a Sitecore item by its ID'), providing a specific verb+resource combination. However, it doesn't differentiate from its sibling 'security-set-item-acl-by-path' which performs the same function but uses a path instead of ID, leaving room for improvement in sibling distinction.

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. It doesn't mention the sibling tool 'security-set-item-acl-by-path' for path-based operations, nor does it explain when to use this versus 'security-add-item-acl-by-id' or other security tools. There's no context about prerequisites, permissions required, or typical use cases.

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