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

Annotations already flag readOnlyHint=false and openWorldHint=true, but the description adds genuinely useful context beyond them: the publish is public-facing ('readers and followers can see it at once'), it reaches other people, requires a confirmation step, and needs the user's Cotlet API key with app access. These are real behavioral disclosures, not restatement.

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 purpose and its public consequence are front-loaded, then confirmation/auth details follow. The confirmation point is stated twice ('you confirm each call' / 'confirm with the user before each call'), which is mildly redundant, but overall the text is tight and earns most of its place.

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 single-parameter, no-output-schema publish tool, the description covers purpose, public visibility, confirmation behavior, and auth prerequisites. Combined with annotations, an agent has everything needed to decide to call it and to warn the user; only explicit sibling routing is missing.

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?

There is one parameter with 100% schema coverage, and the schema already documents story_id as 'Story ID from list_stories.' The description adds no format or sourcing detail beyond that, so the baseline of 3 for schema-heavy single-parameter tools applies.

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 (publish) and resource (a draft/story) and immediately clarifies the outcome: it goes out under your name or in the owning publication and becomes visible to readers and followers. That clearly separates it from create_draft and schedule_story. It stops short of naming a sibling explicitly, so a 4 rather than a 5.

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 gives confirmation guidance (default-on, can be switched off, confirm because it reaches other people), which is a form of when-to-use context. However it never contrasts this tool against alternatives like medium_schedule_story or medium_submit_to_publication, so routing between siblings is only implied by the word 'now'.

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