rename_rack_chain

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

Adds context beyond annotations: 'guarded hierarchy snapshot' implies optimistic concurrency (expectedStateVersion), and the note about return chains (raw label vs Live's prefix) plus the 'use observed name for display, not verbatim restoration' nuance gives behavioral guidance. Consistent with readOnlyHint=false and destructiveHint=false.

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?

Two sentences, front-loaded with the core action, no filler. However, the phrase 'guarded hierarchy snapshot' is vague jargon and could be clearer, slightly reducing precision.

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?

Despite a rich schema, the description omits the essential workflow: that execution requires a prior dryRun to obtain a confirmationToken. It also doesn't mention prerequisites (e.g., chain existence) or differentiate from general rename tools. An agent may attempt an unauthorized direct rename without a token.

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?

Adds meaning to the 'name' parameter with the return-chain naming rule and cautions against verbatim restoration. Also hints at expectedStateVersion's role via 'guarded hierarchy snapshot'. Schema already covers parameters 100%, but the description enriches key nuances.

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?

Description clearly states a specific verb ('rename') and resource ('rack chain'), and mentions a planning mode. It distinguishes from siblings like create_rack_chain and set_rack_chain_mixer by focusing on the naming action.

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?

No explicit when-to-use guidance or comparison with alternatives like rename_session_object. Critically, it does not explain the required two-step flow of dryRun (plan) then applying with a confirmationToken—a key usage pattern for this tool.

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