Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Tool has no description.
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?
Tool has no description.
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?
Tool has no description.
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?
Tool has no description.
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?
Tool has no description.
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?
Tool has no description.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Scored across 14 tools
The tools cover distinct domains like cards, whiteboards, and backups, but some overlap exists within domains. For example, getCard and getCardContent could be confused for retrieving card information, and searchCards/getCardsByArea might have unclear boundaries for finding cards. However, the domains themselves are well-separated, preventing major misselection.
Naming is inconsistent with mixed conventions: camelCase (e.g., analyzeGraph, debugInfo) and snake_case (e.g., get_card_content, list_backups) are both used, and verb styles vary (e.g., 'configure' vs. 'load' vs. 'get'). This lack of a predictable pattern makes the set harder to navigate and less coherent.
With 14 tools, the count is reasonable for a note-taking or knowledge management server like Heptabase, covering cards, whiteboards, backups, and analysis. It's slightly on the higher side but well-scoped, as each tool appears to serve a distinct function without obvious bloat.
The server shows notable gaps in coverage. For cards and whiteboards, there are read/search tools but no create, update, or delete operations, which are essential for a full CRUD lifecycle. Backup tools are more complete, but the core domain lacks write capabilities, potentially causing agent failures in workflows.
