delimit_release_history

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

With no annotations, the description must disclose behavior. It notes 'experimental' but does not explain side effects, read-only nature, or any constraints. The agent is left unaware of whether this tool modifies state or requires permissions.

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 description is extremely concise at 5 words. While it is front-loaded, it sacrifices necessary details. It is not optimally informative for its length.

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 existence of an output schema, return values are covered, but the description lacks context about the tool's scope, data freshness, or how it differs from related tools like delimit_release_status. The 'experimental' tag hints at instability but does not fully prepare the agent.

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%, and the description adds no meaning to the parameters 'environment' or 'limit'. The agent cannot infer allowed values, purpose, or constraints from the description alone.

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 'Show release history' with a verb and resource. However, it does not differentiate from sibling tools like delimit_release_plan or delimit_release_status, and the 'experimental' qualifier adds ambiguity about the tool's reliability.

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 guidance is provided on when to use this tool versus alternatives. There are many release-related sibling tools, and the description lacks any context about prerequisites, intended scenarios, or exclusions.

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