browser_get_title

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

Annotations already declare readOnlyHint=true, openWorldHint=true, and destructiveHint=false, covering the safety profile. The description adds nothing beyond them (no note about empty titles, iframes, or timing after navigation), but nothing is contradicted for a simple read.

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 front-loaded sentence with zero filler. It is as short as it can be while still naming verb and resource, though it offers no structural cues for the workflow.

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 one-parameter, read-only accessor with full schema coverage and no output schema, naming the returned value (the page title) is sufficient for correct invocation. Only workflow hints are missing.

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 lone session_id parameter is documented in the schema as originating from browser_navigate, so the description carries no additional parameter burden. 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?

Specific verb ('Get') plus resource ('the title of the current page'), which cleanly separates it from siblings such as browser_get_url, browser_get_html, or browser_get_text. It does not explicitly name those siblings, so full differentiation is left to the agent.

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?

Usage is only implied: the schema note that session_id comes from browser_navigate hints at the workflow, but the description states no when-to-use, prerequisites, or alternatives. For a trivially scoped tool this is adequate but thin.

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