emu_inspect_fixtures

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

No annotations are provided, so the description carries full responsibility. It says 'Inspects' but does not explicitly state that the tool is read-only or has no side effects. It also doesn't disclose return format, potential errors, or any additional behavioral details. The word 'Inspects' weakly implies read-only, but it is not explicit enough.

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 sentence with no fluff. It front-loads the action ('Inspects and returns') and lists the covered items efficiently. However, it could have used the space to add usage hints, but for a zero-param tool, conciseness is acceptable.

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?

Given no parameters and no output schema, the description provides a reasonable overview of what the tool returns. However, it lacks clarification on read-only nature, any prerequisites (e.g., seeded fixtures), and how this summary differs from other summary tools like emu_get_summary. It is adequate but could be more 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 tool has zero parameters, so the schema is empty and there is nothing to explain. Baseline for zero parameters is 4. Description doesn't need to add parameter info, and it doesn't add any irrelevant detail.

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 the tool's purpose: inspecting and returning a comprehensive summary of specific CUCM cluster elements (nodes, phones, call sessions, policies, buffers). It uses a specific verb and resource list, making it distinct from generic 'get summary' tools, though it doesn't explicitly differentiate from siblings like emu_get_summary or emu_list_nodes.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention that it's a read-only overview, nor does it suggest it as an alternative to more specific list tools (e.g., emu_list_nodes, emu_list_phones). No context on intended use cases or exclusions is given.

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