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

Beyond the annotations (readOnly=false, destructive=false, idempotent=false), it discloses the two-phase state model — the new version waits and the Trust Center keeps showing the current one until publish — plus the exact auth scopes required and the human-approval round trip with a re-call instruction. That is precisely the kind of state, permission, and multi-step behavior an agent cannot infer from the schema or annotations.

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?

Nothing is wasted, but the structure is poor: it opens with a sentence fragment about authentication before saying what the tool does, then packs staging, publishing, and the approval loop into one long colon-chained sentence. Front-loading the action and moving auth/approval into a second sentence would improve it without adding length.

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 moderately complex staged-mutation tool with an output schema (so return values need no explanation), it covers auth, both source types, the waiting state, and the approval-and-retry requirement. The remaining gap is edge-case behavior: an already-staged version, supplying neither url nor evidence_id, or what state the document is left in if approval is denied.

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%, so the baseline is 3, but the description adds real meaning: url and evidence_id are presented as alternatives ('as an https url or an Evidence Vault file (evidence_id)') and publish is framed as the gate that promotes the waiting version, including who may set it. It still leaves unclear whether both url and evidence_id can be supplied together or what happens if neither is.

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 and resource: it keeps a newer version of one Trust Center document (document_id), sourced from an https url or an Evidence Vault file, staged until publish. That distinguishes it from pure evidence tools like trooth_evidence_add and from trooth_documents_stale, but it never names a sibling explicitly, and the fragmented opening clause pushes the actual purpose into the second half of the sentence.

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 clear operational context: you need a sign-in or an agent key with profile:write, publish=true requires profile:publish plus a person's approval, and you must call again once approved. What's absent is an explicit 'don't use this when…' — e.g. whether to use trooth_evidence_add first to stage a file into the Vault before calling this, or how this differs from updating the document record itself.

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