validate_and_reload_project_rate_card

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

With no annotations, the description carries the burden. It discloses that the tool reads a file and returns parsed JSON, and explains the purpose (ensuring the actual generated workbook is used). It does not detail validation checks or error handling, but the read-only nature is clear from the context.

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 efficiently structured with a stage label, a brief rationale, argument explanation, and return type. Every sentence earns its place with no redundancy, and the purpose is front-loaded.

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?

Given the tool has one parameter and an output schema exists, the description adequately covers the why, what, parameter, and return. It provides enough context for an agent to use it correctly without needing additional details.

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 coverage is 0%, so the description must explain the parameter. It clearly states 'local_path: Path to the generated project rate card .xlsx file', adding meaning beyond the schema's bare 'Local Path' label. It could include more format details, but it is sufficient for correct usage.

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 states a specific verb ('reads the generated .xlsx file back into memory') and a clear resource (project rate card from disk). It distinguishes itself from siblings by explicitly tying it to Stage 1b and ensuring Stage 2 uses the actual generated workbook, differentiating it from get_rate_card or create_project_rate_card.

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?

Provides clear context on when to use: after generation and before proposal generation, to load the generated workbook as source of truth. However, it does not explicitly mention alternatives or conditions when not to use it, leaving slight inference to the agent.

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