Observability report

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

Annotations cover the safety profile (readOnlyHint, idempotentHint, destructiveHint=false), so the description need not restate them. It adds useful context about what data is returned (timing snapshots, retention policy), though it doesn't describe freshness, scope, or whether data is aggregated vs. live.

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?

A single, front-loaded sentence that lists exactly what the tool returns with no filler. Every phrase 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?

Output schema exists, so return value details are not required in the description. Annotations cover safety. The main gap is the undocumented `includeRecentEvents` parameter, but for a read-only diagnostics tool this is a minor completeness issue.

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%, so the single parameter `includeRecentEvents` is undocumented in the schema. The description does not mention this parameter at all, leaving its semantics (default true, what events are included) unexplained. Baseline 3 for a one-parameter tool with no compensating description.

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 (Return) and resource (latency budgets, runtime metrics, cache/vendor timing, storage retention policy), clearly identifying this as a diagnostics/observability tool. However, it does not explicitly differentiate from siblings like easyeda_health_check, easyeda_bridge_status, or easyeda_get_server_config, which also serve operational/status purposes.

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 guidance on when to use this tool versus alternatives like easyeda_health_check or easyeda_get_server_config. The phrase 'for performance diagnostics' hints at context but does not name conditions or exclusions.

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