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

Annotations declare this is a write (readOnlyHint=false) and non-destructive, and the description adds the material detail that the recap becomes PUBLIC and that a URL is returned. The 'public' disclosure is important privacy context the annotations do not carry. It does not address idempotency (annotation says not idempotent) or permission requirements, keeping it below a 5.

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 tight sentences, purpose front-loaded, return value second. The trailing 'chat, tweet, report or Slack thread' list is mildly redundant (chat and Slack thread overlap) but still conveys where the output is usable.

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?

With no output schema, the description correctly covers the return value (a URL). For a 3-param mutation tool whose annotations cover the safety profile, it supplies the essential scope and a key public-exposure caveat; missing are permission requirements and whether the public link is indexable or expirable.

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 business_id, focus, and title are already fully documented with the workspace-id provenance and enum values. The description adds no syntax or default details beyond the schema, so the baseline 3 applies.

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?

States a specific verb ('Create') and resource ('public, shareable summary of recent progress for a workspace'), so the agent knows exactly what it produces. No sibling tool performs a comparable share/summarize action, so no confusable alternative is present, but the description doesn't explicitly place itself relative to the CRUD-style siblings.

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 line about the URL going into 'a chat, tweet, report or Slack thread' implies the sharing context, but there is no explicit when-to-use, no prerequisites, and no comparison against any alternative tool. Usage is inferred rather than stated.

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