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

Adds real context beyond the annotations: associated files and mounts are preserved, the change is staged rather than immediately applied, and no human approval gate is involved. These are meaningful behavioral traits (side-effect scope, timing, approvals) that the readOnly/destructive hints alone don't convey.

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?

Four short fragments, front-loaded with the action, with no wasted words. The telegraphic style ('Staged. This call asks no human.') is slightly cryptic but efficient and each sentence earns its place.

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?

Covers the core rename plus the two most important behaviors (preservation and staging), but with five parameters and no output schema, an agent still lacks guidance on what 'staged' implies next (deploy step?) and how expect_revision conflicts surface. Adequate but with clear gaps.

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 80%, so the schema already documents 'to', 'project', 'environment', and 'expect_revision'. The description adds nothing about the 'config' parameter or the revision-conflict semantics, so it neither compensates nor detracts.

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?

States a specific verb and resource ('Rename a Config'), which cleanly separates it from config_remove and config_write. It doesn't explicitly name which sibling to use instead when the intent is something other than renaming, but the action is 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?

There is no explicit when-to-use or when-not-to-use guidance, and no named alternatives among the many config/service/project rename siblings. Only 'Staged' hints at a workflow context, leaving the agent to infer that this is the right tool.

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