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

With no annotations, the description carries the full burden and does well: it discloses that the returned URL is single-use and valid for 1 hour, that the secret never transits the agent, and that the result must be polled via get_connect_link. It omits what happens on expiry or whether a new link must be minted, which keeps it short of a 5.

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-loads the core mechanism and the safety rationale before the workflow and arg list; every sentence is load-bearing. The inline 'Args:' tail is slightly terse and denser than the prose above it, but it compensates for the empty schema.

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?

No annotations and no output schema, so the description must cover behavior and it does: link lifetime, single-use semantics, operator handoff, and the follow-up poll. The remaining gap is parameter meaning for credential_type and label, which nothing else in the definition supplies.

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 description coverage is 0%, so the trailing arg list does real work: provider is tied to list_available_providers, and credential_type/label are marked optional. However, credential_type and label are given no meaning beyond optionality, leaving the agent to guess valid values or label conventions.

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?

States a specific verb and resource: it hands a provider credential to Argus via a single-use URL rather than passing the secret through the agent. The mechanism (URL, 1-hour validity, operator pastes key) makes it unambiguously distinct from connect_provider.

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?

Explicitly routes the agent: 'Prefer this over connect_provider whenever you don't already hold the secret.' It also describes the downstream workflow — show the URL to the operator, then poll get_connect_link for the connection id — so both the selection condition and the next step are stated.

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