Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description fully bears the responsibility. It mentions a behavioral trait ('Costs 1 call') and describes what the output includes (channels, dynamics). However, it omits details on permissions, reversibility, or error states, leaving moderate gaps.
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 description is three sentences long and front-loads the core purpose. It efficiently lists components without excess verbiage, though the list is somewhat dense. A slight improvement would be to break into sub-sentences.
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?
Given the tool's complexity (nested parameters, no output schema), the description adequately explains the output type (Human Design relationship analysis). However, it does not mention return format or pagination, and the jargon 'Canonical Energy Blueprint' may be unclear. Acceptable but not comprehensive.
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 description coverage is 0%, and the description does not explain parameters (personA, personB) beyond what the schema provides. For nested objects with required fields, the description should at least mention the input structure, but it does not, leaving parameter meaning solely to the 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?
The description clearly states it produces a composite/connection chart for two people based on UTC birth instants, listing specific components (electromagnetic channels, dominance, companionship, etc.). It distinguishes itself from sibling tools like bodygraph (individual chart), ephemeris, numerology, sky_personal, sky_today, as none of those focus on relationship analysis.
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 implies usage for relationship analysis via Human Design but provides no explicit guidance on when to use this tool versus alternatives like bodygraph for individual charts. No when-not-to or prerequisite information is given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Each tool targets a distinct aspect of mystical/astrological computation: human design chart, raw ephemeris, numerology, relationship composite, personal natal sky, and current sky overview. No two tools have overlapping purposes.
Tool names are single words or underscore-separated compounds (e.g., bodygraph, sky_personal), all lowercase and noun-like. While there's no verb_noun pattern, the naming is consistent in style and descriptive.
Six tools cover the core functionalities of a mystical API without being too few or too many. Each tool has a clear role, making the set well-scoped.
The tool set covers human design, ephemeris, numerology, relationships, and sky charts. Missing interpretive features like transit readings or detailed compatibility analysis, but core computation is present.
