Get Sequence Structure

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

Annotations already declare readOnlyHint/idempotentHint/destructiveHint=false, so the safety profile is covered. The description adds real behavioral context beyond that: a default 50-clip page, a maximum, payload-budget shortening, and the instruction to follow pagination.nextOffset — genuinely useful for a paged read.

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 dense sentences, zero waste. The pagination instruction is parenthetically front-loaded and the purpose/rationale follows, so the agent gets the operational detail first.

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 an output schema and annotations covering the safety profile, the description need not explain return values. It adequately covers paging behavior and payload contents; only the omission of sibling routing keeps it from being fully 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 100%, so every parameter is already documented in the schema; baseline is 3. The description restates the 50-clip default and pagination.nextOffset but adds no syntax or semantics beyond what the schema provides.

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 ('Get a bounded structural page of the active sequence') and enumerates the payload contents (track counts, paged clips with positions, gaps, clip metadata). The word 'bounded' implicitly distinguishes it from full-sequence siblings like get_full_sequence_info, but no sibling is named explicitly.

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?

'Essential for understanding timeline state before making edits' gives an implied when-to-use context. However, it names no alternatives (e.g., get_full_sequence_info, get_timeline_gaps) and states no exclusions or prerequisites, leaving routing to inference.

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