zerodb_configure_auto_context

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It clearly explains the primary side effect: when enabled, the tool causes relevant memories to be automatically retrieved and prepended to every tool call. It also uses the term 'ambient' to convey the automatic background nature. However, it does not mention details like per-agent scoping or potential performance implications.

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 sentences long and front-loads the primary purpose. It avoids redundancy and provides a concrete example of the behavior ('agents get memory without calling recall() explicitly'). Every word earns its place.

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 configuration tool with no output schema, this description is reasonably complete. It explains the core behavior and captures the value proposition. It could be slightly more complete by mentioning that the configuration is scoped to an agent (which the schema does) or by hinting at the customization parameters, but the essential context is present.

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 100%, so the baseline is 3. The description does not add extra meaning beyond the schema's property descriptions; it only explains the overall feature rather than parameter specifics. The schema already covers 'enabled', 'auto_trace', 'max_results', and 'synthesis_style' adequately, so the description adds no additional semantic value.

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's purpose: to configure ambient memory injection. It uses a specific verb ('configure') and resource ('ambient memory injection'), and it explains what that means by describing the automatic retrieval and prepending of memories. This distinguishes it from sibling tools that perform actual recall or storage operations.

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 when to use this tool by contrasting with 'calling recall() explicitly'—you use it to enable automatic memory injection instead of manual recall. However, it does not explicitly state when to use it versus alternatives like zerodb_get_auto_context_config, nor does it provide any exclusion criteria or prerequisites.

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