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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description earns credit for disclosing the return shape (procedural how-to with screens, buttons, fields) despite no output schema, and for stating it performs no side effects. The stray note about HaloPSA's REST API/MCP endpoint adds no caller-relevant behavior.

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 sentence and the no-side-effects/handoff clause are front-loaded and useful. The closing sentence about HaloPSA's official API and MCP endpoint ("checked 5 Nov 2026") is irrelevant to invoking this tool and reads as promotional filler that dilutes the definition.

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 read tool with no output schema, the description covers what comes back and where to go next, which is what an agent needs. Only the extraneous API/date sentence detracts from an otherwise complete definition.

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?

Zero parameters, so there is no parameter semantics to document and the baseline is 4. The description correctly implies no inputs are needed to retrieve the procedure.

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?

States a specific verb and resource ("Search knowledge base in the user's own HaloPSA account") and clarifies the output shape: step-by-step instructions with screens, buttons and fields. This distinguishes it from action-taking siblings like halopsa_update_ticket or the cotlet_browser_* tools, though it never explicitly names a sibling it is not.

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?

Explicitly tells the agent what this tool does not do ("opens nothing by itself") and hands off the actual work to the cotlet_browser_* tools, which is real routing guidance. It stops short of stating when not to use it or which specific browser tool begins the workflow.

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