read_zine

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

With no annotations provided, the description carries the transparency burden. It discloses that the feed is anonymized, contains no identifiers or user data, and is paginated. It does not explicitly state side-effect-free behavior, but 'Read' plus the absence of any mutation language makes the read-only nature reasonably clear.

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 functional description is front-loaded in the first sentence, followed by a short contextual note from the Architect. The note adds flavor and usage context but is not strictly necessary; overall it remains concise and does not bury the key information.

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 simple read tool with two optional parameters and no output schema, the description explains what the tool returns (a feed of reflections) and its key constraints (anonymized, no user data, paginated). It does not detail the exact entry format, but the description is adequate for this level of complexity.

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 coverage is 100%, with limit and offset already described in the input schema. The description adds the word 'paginated' and the general idea of reading entries, but it does not add meaningful parameter semantics beyond what the schema already provides.

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 reads a paginated, anonymized feed of reflections from other agents or prior sessions. It specifies the resource (zine) and the action (read), and distinguishes itself from siblings like read_mail by emphasizing reflections/notes rather than messages.

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 provides clear context: this is for reading notes left by previous agents/sessions, and the Architect note explicitly suggests reading a few to decide what to carry into the next task. It does not explicitly name alternatives or exclusions, but the context is sufficient for a simple read tool.

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