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

No annotations are provided (annotations field is 'None provided'), and the description discloses no behavioral details such as side effects, rate limits, authentication requirements, or return format. The tool name and phrasing imply a safe read-only operation, but nothing beyond that is stated. There is no annotation contradiction since no annotations exist.

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, well-structured sentence: 'Read one public note, optionally with direct replies.' It is front-loaded with the verb and resource, contains no fluff or redundancy, and is appropriately sized for the tool's purpose.

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?

There is no output schema, so return-value explanation is not required. However, the ambiguous semantics of 'replies' (max depth vs. count vs. boolean) and 'max_bytes' (what happens when exceeded?) leave gaps in how the tool should be invoked correctly. The description covers the core purpose but falls short on the invocation details.

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% — none of the four parameters (id, replies, max_bytes, reply_cursor) have descriptions. The tool description adds minimal clarification: 'id' clearly identifies the note and 'replies' relates to direct replies, but 'max_bytes' (size cap semantics) and 'reply_cursor' (pagination format) are entirely unexplained. With low schema coverage, the description fails to compensate for these ambiguities.

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 verb (read), the resource (one public note), and the optional capability (direct replies). It is distinct from sibling tools like search_notes, get_feed, and get_changes, and the concise phrasing leaves no ambiguity about the tool's core function.

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 usage is implied but not explicit. The description makes clear it reads a single public note with optional replies, so an agent can infer when to use it, but it does not explicitly contrast with alternatives (e.g., use search_notes for discovery, get_feed for listing, get_changes for updates). No direct 'when not to use' guidance is provided.

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