analyze_config

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

With no annotations provided, the description carries the burden of behavioral disclosure. It enumerates the specific risks it flags, providing substantial transparency about what the tool checks. It also discloses a cross-tool behavioral effect (silencing analyze_latency), which is valuable. However, it does not mention return format or whether it makes changes, though the 'analyze' verb implies read-only.

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, dense sentence that front-loads the main purpose and then lists specific flags. While it is somewhat long and lists many items, it is still compact and contains no filler. The structure could be improved by splitting the list, but it remains easily scannable.

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 the tool has no parameters and no output schema, the description is remarkably complete. It details all the major risk checks, including maxmemory, eviction policy, network exposure, authentication, persistence, connection timeouts, keepalive, hz, and latency monitoring. It also explains a cross-tool dependency, making it highly informative for an agent deciding to invoke this tool.

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, and the baseline for 0 parameters is 4. The schema is empty, and the description adds meaning by clarifying the scope of analysis (configuration-specific checks) without needing to explain parameters. The description effectively communicates what is analyzed, making the absence of parameters self-evident.

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 analyzes Redis configuration for security and reliability risks, with a specific list of flags. It distinguishes itself from sibling analyze_* tools by focusing on configuration rather than runtime metrics, making its purpose unambiguous.

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 implies the tool is used when checking Redis configuration, but does not explicitly state when to use it over alternatives. It does add a useful cross-tool note that disabling latency-monitor-threshold silences the analyze_latency tool, which hints at when to correlate tools, but lacks explicit usage guidance.

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