run

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

No annotations are supplied, so the description carries the full behavioral burden. It does disclose the async/background nature, that the job id is returned, that validation runs by default, and that force=true bypasses it. It says nothing about error/failure behavior, whether jobs are cancellable or resource-limited, backend selection implications, or permissions, leaving substantial behavioral gaps for a mutation/launch tool.

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 tight sentences, front-loaded with the action and return value, with the validation/force note before the trailing parameter hints. Efficient, though the terse 'options: extra CLI flags' fragment and the missing mention of validate_first cost some clarity.

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?

An output schema exists, so the job-id return need not be explained in depth, and the description correctly covers validation and flag convenience. But for an 8-parameter launcher with zero schema coverage and no annotations, omitting backend, workdir, and validate_first leaves an agent without enough to invoke it confidently in non-default configurations.

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 8 parameters, so the description must compensate. It explains force ('skip validation'), options (CLI flags, e.g. ['--noplot']), and characterizes omp/mpi_tasks as 'convenience shortcuts,' which is genuine added meaning. But backend, workdir, and validate_first are entirely undocumented, and the relationship between force and validate_first is left ambiguous.

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 gives a specific verb and resource: 'Start a Serpent calculation as a background job and return its job id.' This clearly separates it from the job-management siblings (job_status, job_output, job_kill) without naming them. It stops short of an explicit contrast with validate_input or get_results, so a 4 rather than a 5.

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 conveys the triggering context ('long runs must not block') and the validation default, which implies this is the launcher for non-blocking runs. However, it never states when to prefer validate_input first, when to use job_status to follow up, or what happens if validation fails, so usage is only implied.

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