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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds genuinely useful context beyond that: results are scoped to the authenticated account and "no login switch is required." It does not address the unusual idempotentHint=false on a parameterless list operation, leaving that discrepancy unexplained.

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, front-loaded with the scope-defining half before the return-value note. The phrase "personal context" is somewhat abstract and does the least work in the passage, but there is no redundant or filler content otherwise.

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 parameters and an output schema present, the description need not detail return shapes, and it correctly limits itself to stating what is enumerated and the account scoping. What remains thin is the relationship to team-scoped siblings and whether results are complete or paged, but these are minor given the structured coverage.

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 takes zero parameters, so per the baseline the schema carries the full burden and the description has no parameter meaning to add. Nothing in the description misleads about inputs, and the reference to returned identifiers is the only input-adjacent detail, which 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 uses a specific verb ("Discover") with a defined resource set (personal context, authorized team workspaces, writers, publications), so an agent knows this is an account-scoping/enumeration call rather than a content listing. It does not, however, distinguish itself from nearby siblings such as list_social_accounts or list_medium_publications, which could plausibly return overlapping destination data.

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?

Usage is only implied: "Returns workspace and writer identifiers for team scheduling" hints that this is a prerequisite step before team-scoped calls, but there is no explicit when-to-use statement, no when-not-to-use, and no named alternative. An agent must infer the ordering from the one clause about scheduling.

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