get_optimization_insights

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 usefully adds a security directive that returned DB content is untrusted and must not be treated as instructions, which is genuine behavioral context. However, it does not state read-only semantics, cost/latency expectations, or the shape of what is returned for an 'analysis' tool.

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, both earning their place: the first states purpose, the second gives a prompt-injection safety directive. It is front-loaded and free of filler, though the purpose sentence is generic enough that it doesn't fully orient the reader.

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 and no annotations, the description should do more to explain what the analysis returns and how it relates to sibling diagnostics. The security note is valuable, but the agent lacks enough to know scope, granularity, or when this is the right call.

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%, so both parameters are already documented in the schema, including the unusually detailed RESERVED note on analysis_period. The description adds nothing about parameter meaning or format, so the baseline 3 applies.

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 verb and resource ('Get comprehensive database optimization insights and health analysis'), but 'optimization insights' and 'health analysis' are broad umbrella terms that overlap heavily with siblings like get_index_recommendations, get_performance_stats, and get_connection_health. An agent cannot tell from the description alone how this differs from those narrow tools.

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?

There is no indication of when to call this tool versus the many overlapping siblings (analyze_query_performance, get_index_recommendations, get_performance_stats). No prerequisites, no exclusions, no suggested ordering are provided; the agent must infer usage from the name alone.

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