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

Beyond readOnlyHint=false/destructiveHint=true/idempotentHint=true, it discloses that the API key is stored encrypted and never returned by any tool, that replacing a key leaves the old key verifying notifications for 24 hours, and that one key binds to one application only. It also warns that nothing validates notificationsConfirmed, which is a real behavioral trap the agent could otherwise fall into.

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?

Purpose and permission are front-loaded, followed by the operational rules, then the out-of-scope warning. It is slightly dense in the final sentence about owner-side Tribute steps, but every clause there is actionable rather than filler.

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 an open-world, destructive, non-read-only mutation with four optional params and no output schema, the definition covers prerequisite permission, ordering, return-shape equivalence (same view as get_tribute_setup), and the irreversible/manual steps that must precede it. Nothing an agent needs to call it correctly appears to be 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 100%, so 3 is the baseline, but the description adds cross-parameter meaning the schema does not: the deterministic application order (apiKey, notificationsConfirmed, paused) and the at-least-one-field rule that governs all four optional params. It does not restate parameter details, which is correct given the schema already carries them.

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 first sentence states a specific verb and resource: connect a Tribute account or change the connection, plus the permission required (manage_settings). It is clearly distinguishable from read-side siblings such as get_tribute_setup and from list_tribute_* tools, and it even states that the return value matches get_tribute_setup.

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 concrete usage constraints (must pass at least one field, fields applied in a set order) and explicitly scopes out three actions no tool can do (create key, create/approve product, save webhook in Tribute). It stops short of naming a sibling alternative for reading state, so it is clear context but not full when/when-not routing.

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