get_issue_hashes

Read-onlyIdempotent

Retrieve fingerprint hashes for a Sentry issue to understand why events are grouped together; paginate results with a cursor, 25 hashes per page.

Instructions

Get the fingerprint hashes for an issue (25 per page). Useful for understanding why events are grouped together. Paginate with cursor.

Behavior4/5

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

Annotations already declare readOnly/idempotent/non-destructive, so the safety profile is covered. The description adds real behavioral context beyond that: a fixed page size of 25 and the need to paginate via cursor, which tells the agent to expect multiple calls.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, each earning its place: purpose, motivation, and pagination mechanics, front-loaded with the core action.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a small two-parameter read tool with full schema coverage and no output schema, the description covers purpose and pagination adequately. Only a hint of what a hash looks like is missing, which is minor.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so both parameters are already documented in the schema. The description's mention of cursor pagination mirrors the schema rather than adding new syntax or format detail; baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('fingerprint hashes for an issue') and frames the intent ('why events are grouped together'). It is distinguishable from siblings like get_issue_tags or get_stack_frames, though it doesn't explicitly contrast with them.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The phrase 'useful for understanding why events are grouped together' gives an implied use case, but there is no explicit when-to-use/when-not guidance or named alternative tools. Usage is inferable rather than directed.

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