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

Annotations already declare readOnly/idempotent/non-destructive/closed-world, so the safety profile is covered. The description adds real behavioral context beyond that: inclusion of a later-deleted entry, pagination defaults (limit 20, max 50), continuation semantics, and the explicit note that no captures happen automatically.

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?

Dense but front-loaded: purpose, then pagination, then the alternative and the no-auto-capture caveat. Little wasted text, though the clipped jargon slightly impairs readability.

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?

No output schema exists, so the description should describe the returned items; it gestures at 'capture identities ... including one later deleted' but never explains the has_more/next_before_id contract it references. With 0% schema coverage on three params and no output schema, the description is only partially 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 description coverage is 0%, so the description must carry all parameter meaning. It documents limit's default and max well, but the continuation instruction refers to 'next_before_id' while the actual parameter is 'before_id,' a naming mismatch, and root_id (the required uuid) is never explained.

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+resource ('page ... capture identities for an epic'), which maps to listing feature forecasts, and distinguishes itself from get_feature_forecast. The phrasing is jargon-heavy ('owned immutable capture identities') and does not name capture_feature_forecast or compare_feature_forecasts, but the intent is clear.

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?

Explicitly routes the agent to get_feature_forecast for verification and notes that this list 'does not replay inputs,' which implies when to prefer it over a verification read. However it says nothing about when to choose this over compare_feature_forecasts or capture_feature_forecast, leaving the sibling set only partially disambiguated.

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