rename_glyph

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

With no annotations, the description carries the behavioral transparency burden. It does disclose one concrete behavior, the uniqueness failure condition, but it does not mention side effects, whether references are updated, permissions, or return behavior.

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 two short sentences with no filler. The core action is front-loaded, and the important failure condition is presented as a separate, easily parsed sentence.

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 simple two-string rename operation, the description covers the core action and one key failure case. However, because there are no annotations or output schema, it leaves unanswered what happens if glyph_name is missing and what the tool returns on success or failure.

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 supply parameter meaning. It clarifies that new_name must not already exist and implies that glyph_name identifies the glyph to rename, but it omits naming rules and behavior for a nonexistent glyph_name.

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 glyph') and adds a behavioral discriminator ('Fails if new_name already exists'). It is clearly distinct from sibling tools like create_glyph, duplicate_glyph, and delete_glyph, so an agent can identify its intended role.

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?

There is no when-to-use guidance or comparison with alternatives. The description only states the operation and one failure condition, leaving the agent to infer when rename_glyph should be chosen over related glyph tools.

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