vbstudio_trigger_build

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

The description discloses that the tool is not implemented and is blocked, which is a key behavioral trait. However, it does not describe what happens if the tool is called (error, no-op, etc.) or any side effects, permissions, or rate limits. With no annotations, this is a significant gap.

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?

The description is two short sentences with the NOT IMPLEMENTED marker front-loaded, making it easy to scan. Every word serves a purpose, though it is minimal.

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 tool that is not implemented, the description adequately signals that it should not be used. However, it provides no information about the build trigger behavior, parameter meanings, or relation to other tools, leaving it incomplete for when it becomes available.

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?

The schema has zero description coverage, and the description mentions none of the three parameters (appName, projectKey, environment). The agent has no context for what values these should take, making parameter semantics effectively nonexistent.

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 clearly states the tool triggers a CI/CD build via the VB Studio REST API, which is a specific action and resource. However, it does not explicitly differentiate it from sibling tool run_build or vbstudio_trigger_deploy, so it's clear but not fully distinct.

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 description provides an explicit condition: 'Blocked until a live dev instance is confirmed.' This tells the agent not to use the tool currently, which is a when-not instruction. However, it offers no guidance on when to use this instead of alternatives like run_build or vbstudio_trigger_deploy.

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