caddy_list_routes

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

Annotations already declare readOnly/idempotent/non-destructive, and the description adds significant behavioral detail: output caps (500 routes/20000 chars), whole-route truncation, omission note, and exact fallback path. This fully discloses edge-case behavior without contradicting annotations.

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 that each add distinct value: purpose/output, caps/truncation, and fallback. No redundant filler; structure is well-organized.

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 simple read-only list operation with one optional parameter and no output schema, the description covers output format, limits, edge-case behavior, and how to get the complete data. It is fully self-contained for an agent to invoke and interpret results.

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 only parameter 'server' is already documented in the schema with default 'srv0' and 100% coverage. The description does not add additional parameter-level detail but doesn't need to given the schema.

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?

Clearly states it lists all routes on a Caddy HTTP server and describes the dual output (summary + raw JSON). The use of 'all routes' and explicit reference to caddy_config_get for reading the rest distinguishes it from sibling config-read tools.

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?

Implies use when you want a quick route overview on a specific server, and explicitly directs to caddy_config_get at a specific JSON path for the full untruncated data. The cap behavior and omission note also tell the agent when the result is incomplete.

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