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

With no annotations present, the description must carry the load, and it does a decent job by explicitly naming what is returned ('configuration and pending state') and the fact that it's a read operation ('Get'). It could be improved by clarifying what 'canonical' means or whether any side effects occur (though unlikely for a getter), but for a simple read tool, it sets appropriate expectations.

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 description is a single, efficient sentence immediately front-loading the verb and resource. Every word adds value, and there's no padding or repetition. It's a model of conciseness.

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 getter with no output schema, the description is largely sufficient for an agent to invoke it correctly. The only gap is the ambiguous phrase 'pending state' – an agent might not know what shape this takes or how it relates to the returned configuration. Minor elaboration would push this to a 5, but as-is it's nearly complete.

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 input schema is empty with zero parameters, so the baseline is 4. The description adds no parameter details, but none are needed since there are no parameters to document. This is a clean pass.

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 clearly states a specific verb ('Get') and a specific resource ('canonical CMR publisher configuration and pending state'). It distinguishes itself from sibling tools like emu_get_cdr_publisher and emu_get_syslog_publisher by naming 'CMR publisher', though it doesn't explicitly contrast itself. This is just short of a 5 because it could further disambiguate from emu_get_curri_history or emu_get_contracts_catalog, but the core purpose is unmistakable.

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 usage guidance is provided. The description doesn't state when to use this tool versus alternatives like emu_get_cdr_publisher or emu_get_contracts_catalog. It also doesn't mention whether this is the canonical source for publisher state or when a caller would prefer a different getter. This is a missed opportunity to guide an agent toward the right tool.

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