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

Annotations already flag this as non-read-only, open-world and destructive, but the description adds real context beyond them: the need for revision/version for concurrency, a five-second timeout treated as unknown outcome, and an explicit no-retry-with-new-ID rule. This is valuable behavioral disclosure, though the return semantics remain thin.

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 tight sentences, front-loaded with the core action and followed by prerequisites, return, and timeout/retry guidance. Compact with little waste, though the 'for mutations' clause is terse enough to be ambiguous.

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?

With six undocumented params at 0% coverage, no output schema, and destructive annotations, the description leaves gaps: controlToken is unexplained and 'Returns observed state' is too vague given no output schema exists. It covers retry semantics well but not the full call surface.

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% across six required params, so the description must carry the semantic load. It names revision, version, operation ID and target (partially mapping to four params), but omits controlToken entirely and provides no format or validation detail.

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 gives a specific verb+resource ('Typed component inspect') and locates it in the sandbox, but the phrasing 'an inspected target for mutations' muddles whether this is a read or a mutating operation. It does not distinguish from close siblings like read_component, so an agent cannot easily tell it apart.

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?

It states prerequisites (revision, version, operation ID, target) and gives an important behavioral rule (on five-second timeout, do not retry with a new ID). However, it offers no when-to-use vs alternative guidance against read_component or other sibling tools, leaving selection to inference.

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