fossa_update_release_group

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

Beyond the annotations, the description discloses that it writes to FOSSA and requires the environment variable FOSSA_ALLOW_WRITES=true. It also details partial-update semantics, the ambiguity between omitted and explicit null, and the rejection of setting and clearing the same field. These are non-obvious behavioral traits not captured in annotations or schema.

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 about 80 words, front-loaded with the purpose, and every sentence adds meaningful functional detail. It covers write requirements, partial updates, clear_fields nuances, and scope exclusion without filler.

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 write tool with 8 parameters and nuanced update semantics, the description covers all critical operational aspects: the write requirement and env var, partial update behavior, the clear_fields mechanism, conflict rejection, and the distinction from release updates. An output schema exists, so return-value details are not needed. This is complete for its complexity.

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%, so the description must compensate. It explains that clear_fields is for unsetting nullable fields and clarifies the null ambiguity. The top-level purpose mentions title, policies, portal visibility, and report text, mapping to the parameter names. However, individual parameter meanings (e.g., licensing_policy_id) are not elaborated, but the names are self-explanatory.

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 opens with a specific verb and resource: 'Update a FOSSA release group's title, policies, portal visibility, or report text.' It also distinguishes itself from the sibling tool by stating 'This does not touch releases; use fossa_update_release_group_release for those.' This clearly differentiates its scope.

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?

Explicitly tells the user to use fossa_update_release_group_release for release-level updates, providing an alternative. It also explains when to use clear_fields versus setting a field, and the restriction on setting and clearing the same field. This gives concrete usage context, though it does not enumerate all possible alternatives (e.g., create/delete).

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