Grant skill to project

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

Annotations already declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false, establishing this as a non-idempotent mutation. The description adds nothing beyond that — no indication of what happens on duplicate grants (relevant given idempotentHint=false), no auth requirements, and no side effects disclosed. It merely echoes "create."

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?

At three words it is short, but this is under-specification rather than conciseness — nothing meaningful is front-loaded because nothing is said. Brevity here reflects minimal effort rather than tight editing.

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 three-parameter mutation with 0% schema coverage, no output schema, and a non-idempotent hint, the description is wholly inadequate. It conveys nothing beyond the tool's name, leaving the agent with no guidance on inputs, semantics, or behavior.

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% and the description mentions none of the three required parameters (orgID, skillID, target_project_id). The agent must infer from parameter names alone that skillID is the skill and target_project_id is the grant target. No compensation for the coverage gap.

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?

"Create skill grant" essentially restates the tool name (grant_skills_add) and the title, adding no distinguishing information. It does imply a verb+resource, but the title "Grant skill to project" carries the actual meaning, and the description does nothing to differentiate from grant_skills_list or grant_skills_delete. This is borderline tautology.

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 when-to-use guidance, no mention of the sibling tools (grant_skills_list, grant_skills_delete), and no prerequisites such as required permissions or whether the skill/org/project must already exist. The reader must infer all context.

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