Write Registry Entry

write_registry_entry

Insert or update a registry entry for a model profile, preserving omitted fields to retain existing values.

Instructions

Insert or update one registry entry for a profile/model_id. Omitted entry fields keep their existing values.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {
      "profile": "<profile>",
      "model_id": "<model_id>",
      "entry": "<entry>"
    },
    "name": "write_registry_entry"
  }

A3.9/5.0
Behavior4/5

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

With no annotations provided, the description carries the behavioral disclosure burden. It discloses the crucial upsert behavior and, more importantly, that omitted entry fields retain existing values, which prevents an agent from assuming full replacement. It does not cover return values or error/side-effect behavior, but the core mutation semantics are clearly disclosed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two short sentences with no redundant wording. The primary operation is front-loaded, and the important partial-update nuance is stated immediately after, so every sentence earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a write tool with no annotations and no output schema, the description provides the core purpose and partial-update behavior but omits expected return value, failure modes, and how to confirm the write via read_registry. It is adequate for basic invocation but not fully complete for an agent operating independently.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

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. It does add meaningful semantics by identifying profile and model_id as the entry key and by explaining that entry is a partial set of updatable fields. However, it does not explain the meaning of individual entry fields, leaving some semantics to schema names and types.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb pair ('insert or update') and names the exact resource ('one registry entry for a profile/model_id'), making the operation unmistakable. This clearly distinguishes it from read_registry and other registry-related sibling tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies the tool is for writing registry entries, but it never explicitly says when to choose this over read_registry or other alternatives. There is no exclusion or alternative-routing guidance, so the usage context is clear but incomplete.

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