Consume the link

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

Annotations only give readOnlyHint=false and openWorldHint=true, so the description earns credit for clarifying the write semantics: nothing executes without confirm: true and there is no server-side dry run, i.e. confirm:false only returns a client-side preview. It still omits the outcome of consuming (is the link single-use, does it irreversibly record a decision, what permissions/expiry apply).

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?

Two tightly packed sentences with the endpoint and the write gate front-loaded; nothing is redundant. The brevity is close to under-specification, but every sentence carries information.

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 no-output-schema mutation tool this is the minimum viable: it discloses the write gate and idempotency, but leaves the token's provenance, the resulting state change, and one-time-use behavior unexplained. An agent could call it safely but not predict its effect.

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?

With 67% schema coverage, confirm and idempotencyKey are already documented in the schema, and the description largely restates the confirm behavior rather than adding new meaning. The token parameter is completely undetailed in both places — no explanation of where the token comes from or its lifetime.

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?

It names a verb ('Consume') and resource ('the link') plus the underlying endpoint, but 'consume' does not tell an agent what the operation actually does — approve, reject, or execute a pre-configured decision — and no decision field exists in the schema, so the effect stays opaque. It also fails to distinguish itself from the nearby approvalLinks_preview / approvalLinks_slackInteraction siblings.

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?

The confirm:true gate implicitly signals this is the real-execution counterpart to the preview flow, but the description never says when to call it versus approvalLinks_preview or the approvals_approve/approvals_reject siblings. Usage is inferable rather than stated.

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