black_souls_memory_write

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

Annotations already provide idempotentHint=true and destructiveHint=false. The description adds no additional behavioral context, such as how updates work, conflict resolution, or any side effects. It does not contradict annotations, but adds minimal value beyond them.

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 sentence, which is concise but too brief to be informative. It lacks structure and detail, yet does not contain unnecessary verbiage. It earns a passing score for brevity but loses points for inadequate completeness.

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?

Given five required parameters, no schema descriptions, and an existing output schema, the description is severely incomplete. It does not explain the function of each parameter or the tool's behavior in different scenarios. The agent cannot properly invoke the tool based solely on this description.

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 description provides no information about the five required parameters (key, value, source, category, confidence). Since schema description coverage is 0%, the description fails to compensate, leaving the agent with no guidance on what each parameter means or how to use them.

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 tool stores or updates a long-term game knowledge entry, which is a specific verb and resource. It distinguishes from sibling tools like black_souls_memory_read and black_souls_memory_delete by implying write operations, but does not explicitly differentiate or name alternatives.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., scratchpad_write or session_log_append). The description only states what it does, not when it is appropriate.

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