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

Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=false and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond that: it doesn't say whether duplicate goals are allowed, whether the goal becomes immediately active for the agent team, or what permissions are required to create an org-level goal.

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?

One short front-loaded sentence with no waste, but its brevity reflects under-specification rather than tight writing. It could carry a clause about scope or required fields at no structural cost.

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 mutation tool with no output schema and zero parameter documentation, the description omits what happens after creation (does it return an ID? is there a list_org_goals counterpart?), who can create org goals, and what the two fields mean. An agent could call it, but only by guessing at the payload.

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 burden falls on the description, which never mentions 'title' or 'objective'. The agent gets no hint that objective is optional while title is required, nor any guidance on what a good goal title looks like within the 300-character limit.

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?

States a specific verb and resource: 'Add a company-wide goal'. The phrasing 'company-wide ... for the whole agent team' differentiates it from the sibling create_agent_goal (per-agent scope) and from update_org_goal, even though it never names them.

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 when-to-use guidance, no prerequisites, and no mention of how this differs from create_agent_goal or when to call update_org_goal instead. The agent must infer scope selection purely from the words 'company-wide'.

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