publish

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

Discloses key behaviors: public URL, no account required, unguessable URL, idempotent, world-readable. No annotations provided, so description carries full burden and meets it well.

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, each adding essential info: action, URL property, idempotence and user confirmation. No extraneous words.

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?

Explains return value (public URL), side effects (world-readable), idempotence, and user confirmation. Complete for a single-parameter tool with no output schema.

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 covers parameter 'id' with 100% description coverage. Description adds no extra detail about the parameter beyond what schema provides, 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?

The description clearly states it publishes a packet to a public URL, specifying the resource (packet) and action (publish). It distinguishes from siblings like 'unpublish' and 'save'.

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?

Includes explicit warning to confirm with user before calling, and notes idempotency. Could mention when not to use (e.g., already published) but provides adequate guidance.

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