Update Backlog Issues

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It indicates an update/mutation operation and that it pulls from local task files, but it does not explain side effects, permissions, idempotency, conflict handling, or what happens to issue fields not mentioned. This is a significant gap 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?

The description is a single concise sentence with no filler. The action and resource are front-loaded, but it is arguably too terse to carry all necessary behavioral context.

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 tool with no annotations and no output schema, the description is underspecified. It omits how changes are identified, whether the operation is safe to rerun, how local file changes map to issue updates, and what the agent should expect as a result. An agent could not reliably invoke this tool correctly based solely on the provided description.

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 the single parameter issueKeys already has a clear description with examples. The tool description adds no additional meaning for the parameter, so the baseline score of 3 applies.

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 states a specific verb ('Update'), a resource ('Backlog issues'), and a source of changes ('local task files'), which makes the core purpose clear. It is distinguishable from siblings like get-issue and list-task-files, though its relationship to sync-issues is somewhat ambiguous.

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 a use case—applying local task file changes to Backlog issues—but provides no explicit guidance on when to choose this tool over sync-issues or any other sibling. There are no stated exclusions, prerequisites, or conditions that would help an agent decide between update-issues and the similar sync-issues.

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