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

Annotations already declare the safe read-only, idempotent, closed-world profile, but the description adds genuinely non-obvious traits: append ordering, cursor-based resumption ('Resume with the returned after cursor'), an authentication prerequisite ('Requires the connected identity'), and that results distinguish documentary changes from observed operations.

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, purpose front-loaded, with no wasted words. Each sentence adds a distinct fact (scope, pagination/auth, result semantics).

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 still covers ordering, cursor resumption, auth, and result categorization. The one remaining gap is that it does not differentiate from the sibling get_filtered_changes, but for a one-parameter read tool with annotations carrying the safety profile, it is otherwise complete.

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 coverage is 0% – the single 'after' parameter has no description in the schema. The description compensates by explaining that it is a cursor returned from a prior call and used to resume, which is the essential semantic an agent needs beyond the raw string type and default.

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 gives a specific verb and resource: 'Read append-ordered changes affecting private watched dependencies.' The scoping to private watched dependencies is clearer than the bare name, but it never distinguishes itself from the closely related sibling get_filtered_changes, leaving an agent to infer which list tool to pick.

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?

There is no explicit when-to-use or when-not guidance, and no alternative tool is named. The phrase 'private watched dependencies' hints at the domain but does not tell an agent when this tool should be chosen over get_filtered_changes or get_watchlist.

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