splunk_login

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

With no annotations, the description carries the burden and does well: it reveals browser automation, cookie persistence, SSO-only auth, and troubleshooting steps for IdP/automation failures. It doesn't mention reversibility or that this mutates local state, but the cookie-file note covers the key side effect.

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?

Three dense sentences, each earning its place: what it does, how auth works, and what to do on failure. Front-loaded with the core action.

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 login tool, it covers behavior, side effects, and failure handling. It doesn't explicitly state return values or confirmation of success, but the description's troubleshooting note ('reported cookie file') implies some status output. Minor gap given no output schema.

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?

There are zero parameters, so the schema has nothing to explain. The description's mention of 'reported cookie file' and SSO details adds useful context despite no parameters.

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?

Clear verb+resource: performs SSO login in a browser and saves cookies for the Splunk REST API. It is immediately distinguishable from sibling query/dashboard/report tools as an auth setup step.

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 makes clear it is the SSO-based auth bootstrap for API calls and even gives recovery steps if the IdP redirect or automation blocks the session. It doesn't explicitly say 'run before other tools', but the context strongly implies it.

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