kvp_get

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It says 'Read' which implies a non-mutating operation, but it does not disclose behavior on missing keys, return type, error semantics, or potential side effects. The description adds little beyond what the name 'kvp_get' already suggests, so it falls short of providing meaningful behavioral context.

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, front-loaded sentence: 'Read a value from namespaced KVP storage.' Every word contributes, and it avoids redundancy or filler. It is concise and structured appropriately, though it could have included more guidance without becoming bloated.

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 two-parameter read tool, the description is minimally viable: it states the operation and hints at namespacing. However, with no output schema and no annotations, it does not explain the return value format or behavior when a key is absent. It covers the essence of the tool but leaves gaps that an agent might need to resolve through trial or additional knowledge.

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 description coverage is 0%, so the description must compensate for parameter meaning. The word 'namespaced' hints that 'namespace' acts as a scoping partition, which is a small useful signal. However, it says nothing about the 'key' parameter, value formats, or namespace lifecycle, leaving most parameter semantics to be inferred from the schema names alone.

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 uses a specific verb ('Read') and identifies a tangible resource ('value from namespaced KVP storage'), making the core operation clear. It distinguishes itself from sibling tools like kvp_put, kvp_delete, and kvp_list through the singular 'a value' vs listing, though it never explicitly names alternatives or conditions. This is clear but not maximally explicit about sibling differentiation.

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 such as kvp_list for enumeration or kvp_put for writing. It only states the action, leaving the agent to infer usage from the tool name and parameter schema. There are no exclusions, prerequisites, or routing hints.

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