update_backlog_item

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

With no annotations available, the description must fully disclose behavioral traits. It only states that fields are updated, but gives no details about side effects, validation, overwrite semantics, permissions, or error handling. This is insufficient for a mutation 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?

A single sentence with no filler, front-loaded action, and clear target. Every word contributes meaning; highly 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?

The description covers the core action but lacks important context such as whether multiple fields can be updated simultaneously, behavior on invalid IDs, and response details. With a simple schema and no output schema, this is minimally adequate but leaves gaps.

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% with descriptive parameter definitions, so the baseline is 3. The description adds little beyond restating the fields, and its use of 'or' could be interpreted as implying only one field can be updated at a time, which is not specified in the schema.

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 action ('update') and the resource ('backlog item'), naming the settable fields (status, priority, comment). It distinguishes itself from sibling tools by specifying a general update scope, though it doesn't explicitly contrast with resolve/dismiss variants.

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 like resolve_backlog_item, dismiss_backlog_item, or process_backlog_item. The agent is left without decision criteria for selecting this tool over its siblings.

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