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

Annotations already declare readOnlyHint=true, openWorldHint=true, destructiveHint=false, so the safety profile is covered. The description adds that content is 'hydrated' and that extra details (PR diffs, Jira comments) can be pulled, but says nothing about auth requirements, rate limits, or what happens on partial failures in a multi-line batch.

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 intent and format instruction are front-loaded and clear, but four nearly identical Notion lines (notion.com, www.notion.com, notion.so, www.notion.so) plus three app.notion.com variants pad the text substantially without adding decision-relevant information.

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?

An output schema exists, so return values need not be described. What's missing is behavioral edge-case guidance: how unsupported or mixed URL batches are handled and whether a single bad URL fails the whole call — material for a batch, open-world fetch tool.

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 both parameters are already documented, including the 'verbose' flag with its PR-diff/Jira-comment behavior. The description repeats 'one URL per line' but adds no new meaning 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 pair ('Retrieve and hydrate') and resource ('content from supported URLs'), and the pattern list makes the supported scope concrete. It does not explicitly differentiate itself from siblings context_get_rules or context_research, so it stops short of a 5.

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 enumerated URL patterns effectively define when this tool applies versus when it won't (any URL outside GitHub/Notion/Unblocked domains). However, it never names an alternative tool for unsupported cases or explains what to do when a URL doesn't match.

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