update_kb_instructions

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

There are no annotations, so the description carries the burden of disclosing behavior. It does disclose the key behavior that this overwrite replaces rather than appends, which is useful. However, it does not mention irreversibility, permission requirements, or any side effects on active instructions, which would be important for a mutation tool.

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 two short, direct sentences that front-load the primary action and resource. Every word earns its place, and it avoids repetition of schema details.

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 tool with only two parameters and an output schema, the description covers the core purpose and the key behavioral nuance (replace vs. append). However, it lacks guidance on prerequisites, reversibility, or relationship to sibling tools, leaving some context gaps for a mutation operation.

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%, and the description does not add meaning to the parameters beyond what the input schema already shows. The parameter names 'knowledge_base_id' and 'instructions' are self-explanatory, but no formats, examples, or constraints are given.

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 the specific verb 'Overwrite' and identifies the resource as 'the active instructions on a knowledge base.' It also explicitly notes the behavior 'Replaces, does not append,' which distinguishes it from append-style tools and makes the purpose unambiguous relative to 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?

The description implies the tool should be used when one needs to replace knowledge base instructions, but it provides no explicit when-to-use or when-not-to-use guidance and does not mention alternatives such as get_kb_instructions or update_kc_instructions.

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