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

Annotations already flag destructiveHint=true and idempotentHint=true, but the description adds no context beyond them. It does not warn that replacing a slug can break existing links/references, does not mention the tenant_slug refusal behavior needed with multi-workspace tokens, and does not state that omitted fields are left unchanged. For a destructive mutation, this is a meaningful gap.

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 sentence, front-loaded with the verb and resource, with zero padding. It is efficient but so sparse that brevity shades into under-specification rather than crispness.

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?

An output schema exists and the parameter schema is fully documented, so return values need not be described. However, the destructive nature of slug changes and the tenant-scoping behavior are the key operational facts an agent needs for a mutation, and neither is surfaced in the description.

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 coverage is 100%, so the schema already documents name, slug, new_slug, description (including null-to-clear), and tenant_slug with its multi-workspace rule. The description's field list merely restates the schema at a coarser level and adds no syntax or edge-case detail.

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 ('Rename or update a project's name, slug, or description'), so the agent knows exactly what changes. It does not differentiate itself from nearby siblings such as kb_projects_create, kb_projects_archive, or kb_projects_hide_toggle, leaving the agent to infer separation from the name alone.

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 on when this is the right call versus alternatives. Notable omissions: whether archiving/repurposing is handled by kb_projects_archive, and the fact that changing a slug affects downstream references. The agent gets an action but no decision context.

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