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

With annotations already declaring destructiveHint=true and openWorldHint=true, the description usefully adds that there are 'No provider writes', that exact account/project/branch-head/routing and health checks must pass first, and that either native confirmation or an exact legacy one-use approval is required. These are behavioral details beyond what the annotations provide, though the reversibility of the recorded adoption is not described.

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?

Four short, dense sentences that are front-loaded with the core action and then the preconditions. Every sentence carries substantive information, though the phrasing 'exact legacy one-use approval' and 'exact ... checks' is terse enough to be slightly opaque.

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 destructive, non-idempotent adoption operation with no output schema, the description covers preconditions and confirmation modes reasonably well. But with 0% parameter coverage and no output description, it leaves the agent uncertain about several required inputs and about what the recorded result contains.

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 description must carry the burden for six parameters. It obliquely gestures at account/project/branch-head (app_id, commit_sha) and the 'one-use approval' (approval_id), but says nothing about expected_revision, deployment_id, or protected_deployment, which are required or meaningful inputs.

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 states a specific verb and resource: 'Record an existing current production deployment.' It also names the preconditions (account/project/Git branch-head/routing and health checks), so the agent understands the scope of the operation. It does not explicitly distinguish itself from close siblings like beon_verify_app_release or beon_reconcile_app_release.

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 implies the tool is used to establish a production baseline ('before using it as a production baseline') and mentions confirmation pathways, giving some context. However, it never states when to prefer this over sibling tools such as reconcile or verify, nor when not to use it.

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