forge_persona_update

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

No annotations are provided, so the description must carry the burden of disclosure. It only states that the tool updates metadata, which implies mutation, but lacks details on auth requirements, side effects, rate limits, or whether the update is a merge or replacement. This minimal disclosure is insufficient.

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 two clear, front-loaded sentences with no wasted words. The first sentence states the purpose, the second provides an alternative usage guideline. Efficient and well-structured.

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 updates persona metadata with a nested tags object and no output schema, the description is minimal. It does not explain the return value, whether the update is partial or full, or any prerequisites. While the schema covers parameter details, the description could provide more context for effective use, but it is adequate.

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 100%, so the schema already describes all parameters. The description adds no extra meaning beyond what is in the schema (e.g., explaining the tags pattern or the persona_id role). Baseline 3 is appropriate.

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 'Update persona metadata (tags)' which specifies the verb (update) and resource (persona metadata/tags), and it distinguishes from the sibling tool forge_entity_update by noting that tool is for version changes.

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 explicitly directs to 'Use forge_entity_update for version changes,' providing a clear alternative for a specific case. However, it does not cover other potential alternatives like forge_persona_create for creating personas, so it is somewhat limited.

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