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

With readOnlyHint=false and idempotentHint=true already declared, the description still adds non-obvious behavior: the declaration is invalidated by source changes/restarts or new analysis, it is an attributed model declaration rather than proof of comprehension or human approval, and ingestion does not auto-record analysis. These are meaningful traits beyond the annotations, though conflict/failure behavior is not covered.

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?

It is front-loaded with the core action and each sentence carries information. It is dense jargon but mostly earns its length; only the trailing 'reassemble the dossier' line feels loosely attached to the declaration itself.

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 11 required params, nested revision objects and no output schema, the description covers intent and invalidation but omits how the revision objects must be sourced and matched, which is the riskiest part of a correct call. Given the complexity, a full contract is still missing.

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 only 18% (2 of 11 params described), so the description must compensate. It adds semantics for examinedFragments, requirementIds, conclusion (needs_review) and note, but leaves sourceKey, pageRevision, contextRevision, analysisRevision and expectedReadRevision unexplained, so the revision/versioning contract stays opaque.

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 concrete action: explicitly declaring the examined fragment indexes and linked requirement IDs for a received page after analysis. Verb+resource are discernible ('record document analysis'), but it never contrasts itself with siblings like prepare_document_analysis or submit_analysis, so the agent must infer the boundary.

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?

It gives real when-to-use guidance: declare after actually analyzing a page, explain why a page contains no requirements, or use needs_review for unresolved material. It also notes receiving a page does not record automatically and to reassemble the dossier after coverage changes. No exclusion against alternative tools is named, though.

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