Approve a blocked pipeline

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

Annotations already flag destructiveHint=true, and the description adds a concrete, security-critical behavioral detail: approving runs code from a fork with the repository's secrets. This goes well beyond what the annotation alone conveys and helps the agent understand the real consequence of the action.

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 sentences, zero fluff. The first sentence states the action and condition; the second delivers a crucial warning. Well front-loaded and easy to scan.

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?

The description, annotations, and schema together cover purpose, risk, and all parameters. An output schema exists, so return-value explanation is not required. The only notable gap is that the description doesn't mention the confirm_token flow, which might make the multi-step approval behavior less discoverable, but the schema does at least acknowledge it.

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 100%, so all parameters are already documented and the description doesn't need to repeat them. The description adds no param-specific meaning beyond the schema, which is acceptable given the full schema coverage. The confirm_token workflow is hinted at in the schema but not elaborated in the description.

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 uses a specific verb ('Releases') and resource ('a pipeline that is waiting for approval'), and names the exact status ('blocked'). This clearly distinguishes it from sibling tools like decline_pipeline or cancel_pipeline without needing to inspect their schemas.

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 context for when the tool applies: pipelines waiting for approval, usually from forks. It also advises reading what you approve first. However, it doesn't explicitly mention when not to use it or point to an alternative such as decline_pipeline, so it stops short of full exclusion guidance.

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