setup

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

With no annotations, the description fully covers behavioral traits: it writes to a local file, never transmits data, replaces existing credentials, returns a structured response with validation status, and mentions common errors. No contradictions.

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 concise with 3 sentences and no fluff, but it could be more structured (e.g., bullets for platforms). The front-loading of purpose is good.

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?

Given no output schema, the description explains the return format and a common error. It does not cover all edge cases (e.g., invalid credentials not just missing) or rate limits, but it's sufficient for a simple configuration tool.

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% for the two parameters. The description adds that credentials are 'API credentials as key-value pairs' and mentions missing fields cause VALIDATION_ERROR, but it incompletely lists platforms (missing x, linkedin, reddit, bluesky, mastodon) compared to the schema, which could mislead. Baseline 3, adjusted down slightly for the omission.

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 configures and persists platform credentials to a specific file, using the verb 'Configure and persist' and specifying the resource '~/.pipepost/config.json'. It distinguishes itself from sibling tools like 'publish' or 'activate' by being the only credential setup tool.

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 lists supported platforms and notes that existing credentials are replaced, giving context for when to use. It does not explicitly state when not to use or mention alternatives, but the sibling tool names imply it's for initial setup.

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