vnt_proxy_sjis_encode

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

With no annotations, the description carries the full burden. It discloses a side effect (slots allocation) but does not explain reversibility, state changes, error conditions, or what happens to the input text. The mention of slot allocation is useful but incomplete for a mutation-like operation.

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, tightly worded sentence that starts with the action and includes a parenthetical side effect. No filler, no redundancy, and all words carry meaning.

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?

No output schema is present, but the description does not mention the return value or outcome beyond slot allocation. It is unclear whether the encoded text is returned, stored, or only used for slot registration. The sync_util parameter and the overall workflow implications are left unexplained, making the description incomplete for a tool with side effects.

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 only 50% (sync_util has a description, text does not). The description adds no parameter-specific meaning; it only mentions the allocation side effect, which is not tied to either parameter. For a low-coverage schema, the description should compensate but fails to explain the text parameter or how sync_util affects behavior.

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 action ("Encode") and the resource ("Unicode via SjisTunnelEncoding"), with an explicit side effect ("allocates sjis_ext slots"). This distinguishes it from the sibling decode tool and other vnt_proxy utilities, making the 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 Unicode text needs to be encoded into SJIS, but it does not explicitly state when to use it over alternatives like vnt_proxy_sjis_decode or ext_load. No when-not-to-use or alternative references are provided, so usage guidance is only implicit.

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