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

Beyond the destructiveHint=true/non-idempotent annotations, the description discloses concrete side effects: a private task is saved, reply requests are marked needs_review and 'never completed', and explicitly states 'No peer message or automatic completion is sent'. That is exactly the kind of consequence disclosure an agent needs for a mutating, destructive tool.

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?

Front-loaded with the core action list, then branching detail; each sentence carries behavioral weight and none is filler. It is dense and runs long as a single block, but every clause earns its place for a multi-mode tool.

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?

With no output schema and 8 parameters, the description carries the load well: it explains the four action modes, their side effects, the objective prerequisite, and the edit-then-record workflow. The main remaining gap is the private-credential handling for 'connection', which is only covered in the schema.

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 moderate (63%). The description adds meaning beyond the schema for objective (confirmed commitment in your own words, required for accepting commitments), result_ids (record only after performing edits through revision-checked tools), and revision (current revision). It says nothing about dependency_request_id or connection, but connection is fully documented in the schema, leaving only minor gaps.

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 opens with a specific verb ('Record') and resource ('accepted/applied/dismissed/blocked ... outcome') on a suggestion, clearly distinguishing it from the read-only siblings suggestion_get and suggestions_list. It stops short of explicitly naming those siblings, but the action-set framing makes the tool's role unambiguous.

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 per-branch guidance: accepting a commitment requires a confirmed objective and saves a private task; accepting a reply_candidate links the verified reply; other acceptance is just a review record; and it directs the agent to perform authorized edits through existing revision-checked tools before recording 'applied' with result_ids. It also explains how to correct a misclassification (dismiss with explanation plus an explicit task/request update).

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