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

Annotations already declare destructiveHint=true and openWorldHint=true, but the description goes beyond them by explaining the consequence ('future deployments can change production') and the approval gate. This extra context on impact and authorization is genuinely valuable for a destructive mutation, though it omits reversibility and idempotency (annotations cover the latter).

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 short sentences, front-loaded with the primary action and immediately followed by the impact and the hard gate. No filler or redundancy.

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, open-world mutation with 10 parameters and no output schema, the description supplies good behavioral framing (production impact + approval requirement) but is thin on the parameter surface an agent must populate. Adequate but with a clear gap on inputs.

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% across 10 parameters, including a nested settings object and several beon_* auth/session fields. The description only implies that an approval token is needed (relating to approval_id) and says nothing about project_id, team_id, settings sub-fields, or the beon_* parameters, so it fails to compensate for the coverage gap.

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+resource: 'Update build settings', which matches the actual settings object (buildCommand, rootDirectory, installCommand, outputDirectory). It does not name or distinguish itself from lookalike siblings such as vercel_create_project or railway_configure_service, leaving some ambiguity about which platform/config scope applies.

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 communicates a real precondition ('Requires exact user approval in BEON PASS'), which tells the agent this cannot be fired autonomously. However, it gives no when-to-use vs when-not guidance and names no alternative for adjusting settings.

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