create_milestone

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

Annotations are absent, so the description must disclose behavior. It mentions that session_id defaults to a default session, but does not cover side effects, permissions, or other mutation traits. For a create tool, more transparency is needed.

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, each adding value: purpose and key parameter details. No redundant information. Could be better structured with parameter list, but adequately concise.

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?

Given the tool's complexity (6 parameters, no schema descriptions), the description is incomplete. It omits details on required parameters, usage examples, and potential errors. Output schema exists but still lacks context on what the tool does with inputs.

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%. The description only explains verbosity and session_id defaults, leaving the four required parameters (project_id, name, estimated_start, estimated_finish) undocumented in both schema and description. This is insufficient.

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?

The description clearly states the tool creates a new milestone (sprint) within a project, using a specific verb and resource. It distinguishes from siblings like update_milestone and delete_milestone.

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 explicit guidance on when to use this tool vs alternatives (e.g., update_milestone). It only mentions verbosity levels and session defaults, which are parameter details rather than usage context.

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