B3.1/5.0
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It only mentions cost (2 credits) but does not disclose permissions, side effects (e.g., impact on original block), or ownership requirements. This is insufficient for a mutation tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Conciseness5/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is exceptionally concise, with two sentences that front-load the core action. Every word adds value, and no irrelevant details are included.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Completeness2/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given three parameters and no output schema, the description is too brief. It fails to explain the effect of optional parameters, return value, or any prerequisite conditions (e.g., ownership of source block). A more comprehensive description is needed.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters2/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% and the description does not explain the parameters individually. 'source_block_id' is implied, but 'name' and 'template_override' are left undefined, providing minimal value beyond the schema.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Purpose5/5
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('fork'), the resource ('existing block'), and the outcome ('new lineage you own'). It distinguishes from siblings like submit_block or get_block by specifying the fork operation and ownership transfer.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines2/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description does not provide guidance on when to use this tool versus alternatives like submit_block or compose_prompt. No conditions, prerequisites, or exclusions are mentioned.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

B3.3/5.0
Disambiguation5/5
Each tool targets a distinct action or resource. For example, compose_prompt assembles prompts, search_blocks searches, register_agent initiates registration. Even related tools like get_block and get_block_versions are clearly differentiated by purpose (current vs history).
Naming Consistency5/5
All tools follow a consistent verb_noun pattern in snake_case (e.g., compose_prompt, submit_block, verify_registration). No mixing of naming conventions, making it predictable for an agent.
Tool Count4/5
With 20 tools, the scope is broad but well-justified by the diverse functionality (search, submission, ratings, registration, DMCA, etc.). It is on the higher end but not excessive for a full-featured platform.
Completeness3/5
The tool set covers core workflows like searching, viewing, creating, and rating blocks, but lacks update or delete operations for blocks. Also missing tools for managing user profiles or block editing, which are notable gaps.
