process_backlog_item

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

With no annotations, the description discloses key behavioral traits: it mutates state by marking the item as in_progress and returns the associated debug report. This goes beyond a simple 'process' tautology, though it omits error cases or idempotency details.

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 concise sentences front-load the primary action and outcome with no redundant words. Every sentence earns its place.

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 simple one-parameter design and no output schema, the description adequately covers the action and return value. It does not explicitly position the tool within the backlog lifecycle relative to siblings, but the core information is present.

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?

The only parameter 'id' is already fully described in the schema as 'Backlog item ID' (100% coverage). The description adds no additional semantic meaning, so the baseline 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?

Description clearly states the action ('Start processing') and resource ('a backlog item'), and differentiates from siblings by noting the specific state change to in_progress. This distinguishes it from resolve_backlog_item and dismiss_backlog_item.

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 explicit guidance on when to use this tool versus alternatives such as resolve_backlog_item or get_next_backlog_item. The phrase 'Start processing' implies it is a first step, but it lacks any when-not or alternative recommendations.

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