sentinel_approve_review

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

No annotations are provided, so the description carries the full burden. It does disclose the side-effect behaviors—that drift detection approval re-pins the fingerprint with a new description and injection approval permits the call—which are meaningful mutation consequences. However, it doesn't disclose what happens on failure, whether actions are reversible, or what the return value indicates about success/failure. This is a mutating approval action, so these are notable gaps.

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, one defining the general purpose and one covering the two behavioral variants. No fluff, no repetition of the schema. Efficient and readable, though the structure could optionally front-load the action and relegate nuance to a second sentence—which it already does effectively.

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?

The tool is a mutation with side effects on separate systems (fingerprint re-pinning, call approval) and no output schema. The description covers the primary behaviors adequately but omits the return value, error conditions, and whether either action is reversible. For an approval gate with permanently consequential effects, this is a moderate gap. It's workable but not complete.

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% for the single parameter (itemId is described as 'The review item ID to approve'). The description adds nothing about what a valid itemId looks like or where to obtain it, but with full schema coverage and a single self-explanatory parameter, the baseline of 3 is appropriate. The description's value lies more in explaining the tool's effects than in parameter details.

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 states a clear verb+resource ('Approve a review item') and goes further to explain what approval means for two distinct review types (drift detections re-pin the fingerprint; injection flags allow the call to proceed). This adds meaningful specificity beyond the tool name. It doesn't explicitly differentiate from sibling sentinel_deny_review, but the reciprocal action is implicit from the opposing name—slightly weakening the differentiation.

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 description implies that there are multiple review categories (drift detections, injection flags) and explains what approval does for each, which gives context on when to use it. However, it doesn't state when NOT to use this tool (e.g., when to use sentinel_deny_review instead) or any conditions under which approval is inappropriate, such as whether certain review types should never be approved. The exclusion guidance is absent.

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