knowledge_table

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

With no annotations, the description carries the full burden. It usefully discloses the no-arg behavior, that rows contain fetchable addresses, and the hard rule to use them verbatim rather than constructing paths. However, it says nothing about error handling for bad paths, and the appended '(The area list could not be fetched: HTTP 404 from /v1/regions)' is a leaked runtime failure rather than behavioral disclosure, which muddies rather than clarifies.

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 core is front-loaded and efficient, but the trailing parenthetical HTTP 404 error is extraneous noise that does not belong in a tool definition and makes the description read as half-broken.

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?

With no annotations and no output schema, the description does a reasonable job explaining the routing/address model and the entry-point workflow. It is nonetheless incomplete on failure behavior for invalid paths, and the embedded 404 leaves the agent unsure whether the tool currently works.

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?

Schema coverage is 100% and the schema already enumerates the accepted path forms and states 'Omit for the list of areas'. The description reinforces the 'use addresses verbatim, never construct one' constraint, which is valuable, but adds no new syntax or format detail beyond the schema. Baseline 3 applies.

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?

States a specific verb and resource (fetch a routing table from Knowledge) and explains what the payload is: a list of what is there and where to go next. It implicitly differentiates from knowledge_read/knowledge_circuit by framing itself as the routing/entry-point layer, though it never names the siblings.

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?

Explicitly says to call it with no arguments first and that 'that is where every search starts', which tells the agent when to reach for it. It stops short of naming knowledge_read/knowledge_circuit or stating when not to use this tool.

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