what-is-acp

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

No annotations provided; description does not mention any side effects or auth requirements, but as an educational lesson, the read-only nature is implied. The description is sufficient for the tool's purpose.

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?

Two concise sentences: first sets context (Lesson 14), second explains ACP and its relation to AP2. No wasted words, efficient for agent comprehension.

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 educational tool with no parameters and no output schema, the description fully covers purpose, content, and relationship to sibling tools. Agent can correctly select and use it.

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?

No parameters exist, so schema coverage is 100%. The description adds significant meaning by explaining the content and context of the lesson beyond the empty schema.

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?

Clearly states that the tool is Lesson 14 explaining ACP (Agent Commerce Protocol) and its relationship with AP2. Distinguishes from sibling 'what-is-ap2' by explicitly comparing them.

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?

Explicitly states 'How ACP and AP2 relate, when each applies', giving direct guidance on when to use this tool vs. alternatives. Also frames it as a curriculum lesson.

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