Implementation Reference

  • src/core/brain.ts:129-137 (handler)
    The actual implementation of the getInbox tool logic within the Brain class.
    async getInbox(): Promise<InboxItem[]> {
  try {
    const file = await this.sync.readSection("inbox");
    return parseInbox(file.content);
  } catch (err) {
    if (isNotFound(err)) return [];
    throw err;
  }
}
  • src/tools/inbox.ts:10-10 (registration)
    Registration of the getInbox tool.
    toolHandler("getInbox", async () => brain.getInbox())

Tool Definition Quality

B3.1/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. While 'Get all items' implies a read-only operation, it doesn't specify whether this requires authentication, what format the items are returned in, if there are rate limits, or how 'all' is defined (e.g., pagination, time limits). For a tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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 a single, efficient sentence with no wasted words. It's front-loaded with the core action ('Get all items') and specifies the target ('from the inbox/capture list'). Every part of the sentence contributes directly to understanding the tool's purpose.

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

Completeness2/5

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

Given the lack of annotations and output schema, the description is incomplete for a tool that presumably returns data. It doesn't explain what 'items' are (e.g., tasks, notes, mixed types), the return format, or any behavioral constraints. For a read operation with no structured output documentation, the description should provide more context about what to expect.

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

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has 0 parameters, and schema description coverage is 100%, so there's no need for parameter documentation in the description. The description correctly doesn't mention any parameters, which is appropriate. A baseline of 4 is given for zero-parameter tools when the schema fully covers them.

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

Purpose4/5

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

The description clearly states the verb ('Get') and resource ('items from the inbox/capture list'), making the purpose immediately understandable. It distinguishes this from siblings like getBacklog, getTasks, or getTodayTasks by specifying the inbox/capture list as the target. However, it doesn't explicitly differentiate from saveToInbox, which is a write operation counterpart.

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

Usage Guidelines2/5

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

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention when to prefer getInbox over getBacklog or getTasks, nor does it explain the relationship with saveToInbox. Without any usage context or prerequisites, the agent must infer when this tool is appropriate.

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