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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds meaningful behavioral context beyond annotations: the ADMIN-ONLY access restriction, deduplication behavior, occurrence counts, and the explicit inclusion of failed SP-API sync runs and scheduled tasks. It does not detail non-admin failure behavior or result limits, but the added context is genuinely useful.

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 dense but efficient: one sentence defines the content, one gives the use case, and one compresses all parameters into a single clause. Information is front-loaded (what it is, admin-only restriction before params). Slightly run-on, but every 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?

With no output schema, the description gives a reasonable hint at return shape via 'occurrence counts'. It covers filters, default lookback window, and source services. Gaps are minor: user_id is not mentioned in the prose summary, and there is no pagination or limit information. For a read-only feed tool with 5 optional params, this is nearly 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 coverage is 60%, leaving level, service, and q without full semantic coverage. The description compensates by encoding the enum values ('level (error|warning|throttle), service (web|worker)') and clarifying q as 'search source/message'. It slightly duplicates the schema's hours default and omits user_id, but it adds meaning where ambiguity is highest.

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 specific resource and scope: an 'Operational health feed (ADMIN-ONLY)' that returns 'deduped errors / warnings / API-throttle events' with occurrence counts plus failed SP-API syncs and scheduled tasks. The specificity of content enumerated distinguishes it clearly from sibling tools like account_health_check and account_feedback.

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?

Gives explicit when-to-use guidance: 'Use for "review the ops log" / troubleshooting sweeps', which tells an agent the exact user intent that should route to this tool. It does not name alternatives or state when-not-to-use-this, but the usage context is unambiguous enough to select correctly among siblings.

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