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

With no annotations provided, the description carries the full burden of behavioral disclosure. 'Create a new release' implies a write operation but doesn't specify permissions required, whether it's idempotent, error handling, or what happens on success (e.g., returns a release ID). It misses critical details like rate limits, side effects, or response format, leaving significant gaps for a mutation 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?

The description is a single, efficient sentence with zero waste—'Create a new release' is front-loaded and directly states the purpose without unnecessary elaboration. It earns its place by being maximally concise while conveying the core action.

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 the complexity of a creation tool with 6 parameters, no annotations, and no output schema, the description is incomplete. It doesn't cover behavioral aspects, usage context, or return values, making it inadequate for an AI agent to reliably invoke the tool. More detail is needed to compensate for the lack of structured data.

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 100%, so the schema fully documents all 6 parameters (e.g., 'body' as release description, 'prerelease' as boolean). The description adds no additional meaning beyond the schema, such as explaining parameter interactions or constraints. Baseline 3 is appropriate when the schema handles parameter documentation effectively.

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 'Create a new release' states the action and resource clearly but is vague about what a 'release' entails in this context. It distinguishes from siblings like 'release_list' by specifying creation vs. listing, but doesn't clarify the domain (e.g., software releases, database releases) or differentiate from other creation tools like 'backup_create' or 'gitea_create_repo'.

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?

No guidance is provided on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing a repository setup), exclusions, or relationships with sibling tools like 'release_list' for viewing releases or 'version_bump' for version management. The description lacks context for appropriate usage scenarios.

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