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

readOnlyHint=true already declares this is a safe read, so the safety burden is lifted. The description adds the useful detail of exactly what is returned (content + rulesRevision) and the task/work-type dependency, but omits any format, failure mode, or authorization context.

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 tightly packed sentences that lead with the return payload and follow with the conditional task rule. No filler, though the phrasing is dense enough to read slightly awkwardly.

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?

With no output schema, the description usefully names the returned fields (content, rulesRevision) and the work-type conditional. For a 2-param read tool this is close to sufficient; a pointer to the consuming create tools would make it complete.

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 both enums are self-documenting, so the schema carries the load. The description's note that the task template depends on work type adds marginal motivation for taskType but no syntax beyond what the schema already states.

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 it returns workspace conventions, a description template, and a rulesRevision for feature/task/bug creation, which is a specific verb+resource. This notably clarifies a misleading tool name ('create_rules' implies a write). However, it names no sibling to distinguish itself from, e.g., evaluation_rules or the *_create 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?

The description implies this is fetched before creating a feature/task/bug ('templates that creation requests carry'), giving usable context. But it never explicitly says when to call it versus the create tools, nor any exclusions or prerequisites.

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