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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds genuinely useful behavior: statuses carry a 'category' (open/in_progress/resolved/closed/backlog), statuses are returned in workflow order, tags are excluded, and returned text is untrusted. It does not discuss error behavior for a bad project_id.

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?

Front-loads the core fetch action, then layers the practical consumer information (filter values, category meaning, tag exclusion). Dense but nearly every sentence carries actionable meaning; the untrusted-data warning is a required safety line rather than filler.

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?

No output schema exists, yet the description fully describes the return shape (statuses/priorities/types, each with id and name; statuses additionally with category and workflow ordering) and its consumers. An agent has everything needed to call it and interpret the response.

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 ('public code', e.g. from list_projects), so the description need not restate it. The description adds only indirect context via the id/name duality of the returned collections. Baseline 3 is appropriate.

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 ('Fetch one') and resource ('Ybug project') and enumerates the config payload (statuses, priorities, types). The word 'one' plus the references to list_feedback/list_tags clearly separate it from list_projects and list_tags.

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?

Explains the downstream purpose of the returned data — id/name pairs are valid values for the 'statuses', 'priorities' and 'types' filters on list_feedback and the corresponding update_feedback arguments — and explicitly routes tags elsewhere ('Tags are not included; use list_tags'). It stops short of an explicit 'use this when you need a single project vs list_projects' statement.

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