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

With no annotations, the description carries the behavioral burden and does disclose persistence to a dedicated store and the write-only nature of the tool. However, it does not explain whether 'enrich' overwrites or merges an existing context, whether calls are idempotent, or what failure behavior looks like.

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?

Three short sentences, each earning its place: the action, the condition for use, and the persistence side effect. The most decision-relevant information is 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 5-parameter write tool with no annotations and no output schema, this description is too thin. It defines the tool's role but leaves the meaning of multiple parameters unexplained and says nothing about return values, so an agent cannot confidently construct a correct call beyond the required context field.

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 only 20%, so the description needed to compensate by explaining parameters like axes, keywords, and description, but it does not. It only names 'context' without giving semantics for that required parameter or any of the other top-level fields.

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-resource pair ('Create or enrich a context') and clearly delimits the tool's purpose: promoting a reusable lens rather than analyzing or validating. The phrase 'the only write door' distinguishes it from the sibling tools without needing their schemas.

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 gives an explicit use condition: only promote a lens reusable beyond the current subject, and only through deliberate promotion, never automatic. It does not name the sibling alternatives for when to use them instead, but the 'only write door' phrasing clearly separates this from the other tools.

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