Read the living style directives

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

No annotations are provided, so the description carries the burden. It discloses that directives are mutable, current, layered on the durable skill, and change over time, which is useful context. However, it does not describe the response structure or edge cases (e.g., missing directives), leaving some ambiguity for a tool with no output schema.

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 sentences, dense with relevant detail; every phrase adds value, with the key action and timing front-loaded.

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 a zero-parameter read, the description is mostly complete: it states what is returned (mutating style directives), when to call it, and why. The lack of an output schema means a reader might want more detail on exact return format, but the description provides enough context to select and invoke the tool.

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?

The tool has zero parameters, which is the baseline for a 4. The description avoids any unnecessary parameter discussion.

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 uses a specific verb ('Return') and identifies the resource ('current, mutable style directives'), clearly distinguishing this read operation from the write-focused sibling style_set_directives by emphasizing 'current-season focus' and 'recent preference updates' over the static skill.

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?

It explicitly instructs to call this 'at the START of any styling task', providing clear timing and purpose (so recommendations reflect the latest direction). It does not list exclusions or alternatives, but the guidance is sufficient for a simple read tool.

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