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

Annotations declare readOnlyHint=false, destructiveHint=false, openWorldHint=true, which is an unusual profile for something named 'propose'. The description's 'propose' framing helpfully implies no DDL is executed, resolving that ambiguity somewhat, but it says nothing about whether a proposal is persisted, whether it requires human approval, or what happens on a log with no identifiable error.

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 well-front-loaded sentence with the action and object stated immediately and zero filler. It is arguably too terse for a three-parameter workflow tool, but there is no wasted text.

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 carries the burden of explaining what a 'proposed fix' looks like (raw DDL? diff? warning?), and it does not. The safe-to-call character is implied but unconfirmed, leaving the agent to guess at the response shape and the propose/apply handoff.

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 dbSourceId, logSnippet, and the optional deploymentId are already fully documented in the schema. The description adds no syntax, format, or linkage detail beyond that (e.g. how deploymentId changes the analysis), 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 specific verb pair (analyze, propose) and resource (deployment log errors → DDL fix), so the agent knows this is an analysis-and-suggestion tool rather than an executor. It does not name the obvious sibling nexusai_db_apply_fix, so the boundary between proposing and applying must be inferred.

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 when-to-use guidance, no prerequisites, and no mention of the apply_fix alternative that clearly follows this tool in a workflow. The agent gets no explicit signal about when this is the right call versus inspecting schema or querying directly.

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