Search gists

search_gists
Read-onlyIdempotent

Search gists by title, description, topics, or owner with filters for scope, visibility, and update time.

Instructions

Find gists by title, description, topics or owner. Opengist has no search API, so this pages through the list endpoints and filters client-side — it is therefore bounded and can be incomplete; the result always says how much was scanned and whether it was cut short. Searching inside file contents is not supported (it would mean downloading every file of every gist): narrow the field here, then read candidates with get_gist.

TDQS

A4.7/5.0
Behavior5/5

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

Beyond the readOnly and idempotent annotations, the description discloses that the tool pages through list endpoints, is bounded and can be incomplete, and returns information about scan coverage. This is transparent about limitations and behavior.

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?

The description is concise and well-structured, with two clear sentences that convey purpose, limitations, and guidance without unnecessary fluff.

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

Completeness5/5

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

The description provides sufficient context about the tool's behavior and output (e.g., indicating how much was scanned and whether it was cut short). It is complete given the output schema exists and the description covers key aspects needed for correct usage.

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?

The input schema already provides detailed descriptions for all parameters (coverage 100%). The tool description adds some context about the overall approach but does not significantly enhance parameter semantics beyond the schema's existing descriptions, warranting the baseline score.

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

Purpose5/5

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

The description clearly states the tool's function: finding gists by title, description, topics, or owner. It also distinguishes itself from siblings like get_gist by explaining it pages through list endpoints and filters client-side.

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

Usage Guidelines5/5

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

The description explicitly explains when to use this tool (for metadata-based search) and when not to (file content search is unsupported). It also guides users to narrow the field and then read candidates with get_gist, providing clear alternative usage.

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