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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds two genuinely useful facts beyond that: the result is a signed object and the call costs $0.75 USDC. It still says nothing about what the plan contains or what happens with the ten optional inputs.

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?

Short, and the purpose is front-loaded, but the second half is a run-on fragment ('use it rather than ... for remediation plan, not dependency risk; a signed result object. $0.75 USDC.') that reads as machine-truncated rather than deliberate. The cost and signed-output facts deserve their own clean sentence.

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?

An output schema exists, so return values need no explanation. But a ten-parameter tool with zero required parameters and boilerplate schema text leaves the agent unsure which inputs actually drive the plan — the description should name the essential input (findings) and note that cost is incurred per 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 nominally 100%, but every parameter description is generic boilerplate ('The task this operation operates on. See the schema...'). The prose only indirectly points at `findings` by mentioning 'security findings'. With ten all-optional, undocumented-in-substance parameters, a baseline 3 is the ceiling.

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+resource: 'Turn an agent's security findings into an actionable fix list.' This distinguishes it from risk-assessment siblings, and it explicitly names `assess_dependency_risk` as the one it is not. Slightly marred by the fragmentary phrasing, but the intent is unambiguous.

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?

Explicitly names the alternative tool and the condition that selects it ('use it rather than `assess_dependency_risk`'). However the clause 'for remediation plan, not dependency risk' is garbled, and there is no guidance on prerequisites (do findings need to come from `run_agent_security_scan` first?).

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