Deploy and Run Ballerina Project on WSO2 Integrator Runtime

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

Annotations declare readOnlyHint=false and destructiveHint=false, providing baseline safety info. The description adds that the service runs in the background, returns a PID for later stop via sf_stop_project, and waits for the listener to come up. This adds behavioral context beyond annotations.

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?

Three sentences, each earning its place: first states action, second explains port handling, third describes return values. Front-loaded with key information. No redundant or filler content.

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?

Given tool complexity (2 params, no output schema), the description adequately covers purpose, outcome (started=true, PID), and linkage to stop tool. It could mention error states or prerequisites, but overall complete for its scope.

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 already describes both parameters (project_path, port) with descriptions and constraints, achieving 100% coverage. The description adds that the port is passed as a configurable override and that service_url matches the listener, enhancing understanding beyond schema.

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 starts a Ballerina service via 'bal run', passes a port, and returns started=true and a PID. It distinguishes from siblings like sf_build_project (build only) and sf_stop_project (stop).

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?

There is no explicit guidance on when to use this tool vs alternatives, but the context signals show siblings like sf_build_project and sf_stop_project, and the description implies use after building. However, it lacks explicit when-not-to-use or alternative tool mentions.

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