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

Annotations already declare readOnlyHint/idempotent/non-destructive, and the description adds genuinely new behavioral facts: nothing is created yet (status 'prepared' until publish), catalogue name uniqueness is reused automatically, never rename to force uniqueness, and the returned url must be passed through verbatim. That is well beyond what the annotations convey.

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-loaded with purpose and the primary routing rule, with dense but non-redundant sentences. It is on the long side and the catalogue-uniqueness passage is somewhat sprawling, but nearly every sentence carries operational information.

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?

There is no output schema, yet the description explains the return value (url, used as-is), the deferred-creation semantics, required inputs and the sibling tools to consult first. For an 8-param tool with rich annotations, nothing an agent needs to call it correctly is missing.

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 100% and each parameter (roles, skills, valph, nhours, descrip, workways) is documented in the schema itself. The description only adds the projectId sourcing hint and the catalogue-matching nuance, so the 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?

Opens with a specific verb+resource ('Prepare the mission creation form') and states the concrete output (a pre-filled link). It goes further by defining what a mission is ('work that needs an implementer to be found'), which cleanly distinguishes it from createTaskTool and the get* inspection tools.

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?

Explicit when-to-use ('when the user should review and confirm the mission before it is published'), explicit alternatives ('create a task (act) on it with createTaskTool instead'), and a prerequisite check ('Check the rikma's open missions (getProjectDetailsTool) first'). It also names findUserProjects as the way to obtain a missing projectId.

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