program_scope_start

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

With no annotations provided, the description carries the full burden of explaining behavioral effects. It states 'Start or update' but does not disclose whether starting a scope with an existing name overwrites/merges data, whether approval workflow is triggered, or what side effects (e.g., changes to active engagements) may occur. This lack of detail is a notable gap for a tool that creates/modifies program scope.

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 structured as a clear list of parameters, each with an explanation and example. While slightly lengthy, every line adds value for parameter understanding. The opening sentence is concise and front-loaded, though the parameter details could be considered repetitious if the schema were richer.

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 with six parameters and no annotations, the description adequately explains input semantics but omits important contextual information: no mention of return values, side effects, approval requirements, or differences from sibling tools. This makes it minimally viable but not fully complete for an agent to safely and effectively use the tool in all scenarios.

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%, yet the description fully compensates by explaining each parameter with concrete examples (e.g., 'in_scope: list of allowed targets e.g. ["10.10.10.0/24", "example.com"]'). All six parameters are meaningfully described, making the tool easier to invoke correctly without schema hints.

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's function: 'Start or update a named program scope,' using a specific verb and explicit resource. It distinguishes itself from sibling tools like program_scope_list or program_scope_end by focusing on creation/update rather than viewing or terminating.

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 implies when to use the tool (starting or updating a named program scope) and provides context through parameter definitions. However, it does not explicitly mention alternatives or exclusion criteria, such as when to use program_scope_add_targets instead of this scope-creation tool.

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