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

Beyond the annotations, it discloses idempotence, workflow state constraints, that recurring issues arrive switched off, legal-reference and due-day defaults, preset-specific exceptions for agents/jira/season, sample labelling, language behavior, and the required permission level. These are exactly the mutation-side effects an agent needs before invoking the tool.

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?

The purpose and key idempotence rule are front-loaded, and nearly every sentence adds operational detail relevant to correct invocation. The single dense paragraph is information-rich but could be easier to scan; length is justified by the tool's branching behavior.

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 complex mutation tool with no output schema, the description covers permissions, idempotence, preset-specific behavior, side effects, follow-up tools, and sample handling. Nothing essential for correct invocation appears to be 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 coverage is 100%, so the baseline is 3, but the description adds meaningful semantics for several parameters: 'samples' files labelled sample content that can be removed together, 'language' controls naming and can be renamed later, and preset behavior varies materially by value. Some parameter details remain schema-only, so it does not quite reach 5.

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 opens with a specific verb and resource: 'Give a project a ready-made setup,' and immediately points to list_project_presets as the discovery counterpart. It clearly distinguishes applying a preset from listing presets, and the preset-specific effects further confirm what the tool does.

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?

It states the core usage condition (apply only what the project does not already have, so taking it twice adds nothing) and explains workflow-specific restrictions. It also points to list_project_presets for discovery and to set_issue_schedule for follow-up, though it does not broadly compare against alternatives like create_project.

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