daily_blessing

Draw today's deity card from a collection of 1,069 deities, based on birth date and current date. Returns deity name, mythology origin, tier, and daily message.

Instructions

Draw today's deity card from Mythsensus's 1,069-deity collection. Deterministic given (birth date, current date) — the same chart on the same day always draws the same deity. Higher Cosmic Score chart tiers are biased to draw rarer-tier deities. Returns deity name, mythology origin (Hindu, Norse, Yoruba, etc.), tier (Common→Mythic), and today's message. This is a simplified version of the website daily blessing.

Behavior3/5

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

Discloses determinism, bias due to Cosmic Score, and return fields. Missing details on error handling, input validation, rate limits, or auth requirements. No annotations to supplement, so some gaps remain.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, front-loaded with main action. No extraneous words, though the 'simplified version' note adds little value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 4 params and no output schema, description covers deterministic behavior and return fields but lacks details on error cases, parameter dependencies, or how the optional 'date' interacts with required year/month/day.

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 low (25%) and description does not compensate. Although it mentions 'birth date' and 'current date', it doesn't clearly map to the four parameters (year, month, day, date) or explain their roles beyond the schema's minimal descriptions.

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?

Description clearly states verb 'Draw' and resource 'deity card' from a specific collection. Distinguishes from sibling tools like calculate_cosmic_score or get_deep_reading by being a daily blessing draw.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides context on determinism and bias, but does not explicitly state when to use this tool vs alternatives or when not to use it. Sibling get_deep_reading could be an alternative but no comparison given.

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