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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered. The description adds that it reflects the project 'as it stands' (a point-in-time snapshot), but does not cover permissions or pagination/activity-window limits. It also largely restates the returned field set that the output schema already defines.

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?

Two sentences, zero filler, with the read scope front-loaded and the id-discovery hint placed last where it is needed. Every clause earns its place.

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 single-parameter read tool with rich annotations and an output schema, the description supplies everything an agent needs: what it returns, when to use it, and where the required id comes from. No material gap remains.

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% and the single parameter is fully documented in the schema (uuid, sourced from THIS PROJECT or a project link). The description adds only the pointer to twelfth_list_projects for discovering an id, which is marginal value over the structured field.

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 (read) and resource (one project) and enumerates what the read exposes: workflow stage, scope, owner, open tasks, documents, artefacts and recent activity. It also names the sibling twelfth_list_projects as the way to obtain an id, so the agent can separate it from list-style siblings.

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 states the use case ('where a piece of work is up to and who holds it') and routes the agent to twelfth_list_projects when only an id is needed. The alternative and the condition that selects it are both named.

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