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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds meaningful context beyond that: the tool only returns instructions, opens nothing itself, and requires a follow-up browser session in the user's own Productboard account. It does not cover prerequisites such as whether a Cloud Browser session/Productboard login must already exist, which keeps it from a 5.

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 first two sentences are front-loaded and carry the actionable content efficiently. The final sentence is a long digression about Productboard's REST API and beta MCP server, complete with an oddly future-dated "checked 22 Oct 2026" stamp, that does little to help an agent invoke this tool and dilutes the focus.

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 zero-parameter, no-output-schema guidance tool whose annotations already cover safety, the essentials are mostly present: what it returns and which tools to use next. Missing are the inputs' origin (how the feature and status are identified), prerequisites for the Cloud Browser handoff, and what the response looks like if the feature cannot be resolved, which an agent would want before committing to the two-step flow.

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?

With zero parameters the nominal baseline is 4, but this is an operation that inherently needs a target feature and a target status. The description never explains how those are supplied (presumably from conversation context), which is the one piece of parameter semantics an agent would need here. The empty schema at 100% coverage is technically complete, so this is a modest deduction rather than a severe one.

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 and resource ("Update feature status") and then sharply redefines the mechanism: it "Returns how to do it in Productboard step by step (screens, buttons, fields) and opens nothing by itself." That distinguishes it from the cotlet_browser_* tools it hands off to. It loses a point because the name/title imply a mutation while the actual purpose is to emit instructions, so the agent must parse two sentences before the real behavior is clear.

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?

There is a clear sequencing instruction: call this first for step-by-step guidance, then execute with cotlet_browser_* tools in the user's Productboard Cloud Browser. However, the closing sentence about Productboard's official REST API v2 and the beta MCP server at mcp.productboard.com names alternatives without saying when to prefer them over this tool, leaving a routing ambiguity for the agent.

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