rename_glubler

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

With no annotations provided, the description carries the full burden for behavioral disclosure, but it only restates the core operation and scope. It does not mention permissions, side effects on subglublers or links, reversibility, or what happens after a rename. The 'auto-uniquified' detail for slugs appears only in the schema, not the description, so the description adds little behavioral value beyond the structured fields.

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 appropriately short and front-loaded with the action in the first sentence. The second sentence clarifies the fields affected. The third sentence ('Works for both top-level glublers and subglublers') is somewhat redundant with the glublerId schema description but still provides useful scope without bloating the text.

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 mutation tool with no annotations and no output schema, the description is adequate but not complete. The schema fully documents the parameters, so the main gap is behavioral context: no mention of authentication, cascading effects on subglublers, or response/errors. Since the operation is simple and the params are well-covered, this is a minor gap rather than a critical one.

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 baseline is 3. The description does not add parameter-specific meaning beyond the schema; it only summarizes that title and/or slug are updated, which is already evident from the schema's property descriptions. No extra semantic guidance is provided.

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 opens with a specific verb and resource: 'Rename a Glubler or subglubler (nested collection).' It then clarifies what changes ('Updates its display title and/or URL slug') and explicitly covers both top-level and nested entities, clearly distinguishing this tool from siblings like create_glubler, delete_glubler, and list_my_glublers.

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 usage context is implied rather than explicit: the description states that it works for both top-level glublers and subglublers, which hints at applicability, but it does not name alternatives or conditions for when not to use this tool. There is no explicit when/when-not guidance, though the sibling list makes it the obvious rename tool.

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