estimate_infrastructure

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

Since no annotations are provided, the description carries the behavioral transparency burden. It does disclose meaningful behaviors beyond the name, such as checking free tiers and budget caps and comparing providers. However, it does not state whether the tool is read-only, what output is returned, or how it behaves when budget caps are exceeded.

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 two focused sentences with no filler. The core action is front-loaded, and each clause adds a distinct capability, making it concise and scannable for an agent.

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?

For a tool with five parameters, no output schema, and no annotations, the description covers the main capabilities but leaves return-value format and edge-case behavior unstated. It is adequate for initial tool selection but not fully complete for reliable invocation without further inference.

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?

All five parameters have schema descriptions, so the baseline is 3. The description adds some semantic linkage by suggesting stack_components are providers to compare, scale feeds scaling projections, and monthly_budget_usd enables budget cap checks, but it does not substantially enrich parameter-level meaning beyond the schema.

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 uses a specific verb and resource: 'Estimate monthly infrastructure costs,' and adds distinctive scope with scaling projections, provider comparisons, free tiers, and budget caps. It is clearly a cost-estimation tool, though it does not explicitly distinguish itself from sibling tools like simulate_cost or estimate_project.

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?

The description implies the usage context: assessing monthly infrastructure costs with scaling and budget considerations. However, it provides no explicit when-to-use guidance, exclusions, or differentiation from the many cost/planning sibling tools available.

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