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

With no annotations, the description carries the full burden and does well: it discloses the auth requirement and the 403 failure mode, the preview-by-default behavior, and that publishing is irreversible. It stops short of saying where the post lands, whether it can be edited or deleted afterwards, or any rate limits.

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?

Three sentences, zero waste, correctly ordered: what it does, who may call it, then the preview/publish switch with its irreversibility warning. The destructive detail is front-loaded where an agent will see it before acting.

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 an irreversible tool with no annotations and no output schema, the description covers the critical gaps: permissions, default safety posture, and irreversibility. It omits what a preview actually returns and which LinkedIn identity receives the post, which would matter when the agent reports results back.

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 every parameter is already documented in the schema, including the dryRun default and the postText constraint. The description reinforces the dryRun default but adds no new syntax or format detail for slug, contentType, locale, or category, so baseline 3 is appropriate.

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?

States a specific verb and resource: composing a LinkedIn post from a published DevSpeak article. This is unmistakably distinct from the language/translation siblings (translate_text, summarize_input, refine_translation), so an agent can route correctly without opening the schema.

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?

Gives the precondition for use (DevSpeak administrator privileges; standard API key gets 403) and the safe-invocation path (defaults to preview, pass dryRun:false to publish). It does not name or compare against any sibling alternative, but for a single-purpose publishing tool the context is clear.

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