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

No annotations are provided, so the description carries full burden. It discloses that the tool takes no arguments, returns hashes/provenance data rather than compute output, and is read-only in nature. It clearly states the semantic limits of the verification (proves integrity/reproducibility, not data correctness). It doesn't mention performance or failure modes, but given zero annotations, it does substantially better than baseline.

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 dense but well-structured: it states what the tool returns, gives a concrete usage workflow, notes a caveat, and ends with an actionable instruction—all in four sentences. Nothing is wasted and the critical usage guidance is front-loaded after the initial purpose statement.

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 zero-argument tool with no output schema and no annotations, the description is remarkably complete: it explains the return content (hashes, generator, page), provides the verification workflow, discloses limitations, and notes citation behavior. There are no ambiguity gaps for an agent invoking this tool.

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 100% and there are zero parameters, so the description is not required to explain any. The description correctly states 'Takes no arguments,' preempting any agent confusion about input. The baseline for 0-param tools is 4, and the description's explicit confirmation elevates it further since there is nothing left ambiguous.

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-resource pairing ('Get the MFG Calcs Provenance Manifest') and clearly enumerates what the manifest contains: SHA-256 hashes, generator, page, and git history for every indexed/ledger artifact. It distinguishes itself from sibling data-retrieval tools by being specifically about provenance/verification rather than data values.

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 explicitly says 'Use this to VERIFY a number before quoting it' and provides a concrete three-step workflow (re-hash for integrity, re-run generator for reproducibility, read git history for timestamp). It also gives an explicit caveat about what the tool does NOT prove (correctness of underlying government data) and instructs the user to cite the returned url.

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