SigRank — AI Operator Benchmarking

Export SigRank Standard Record

get_sigrank_standard_record

Read-onlyIdempotent

Build a SigRank Standard v0.1-draft portable operator record from available token telemetry. Input and output are required; unavailable cache telemetry remains null. Computes only the five-metric portable core through @sigrank/cascade and does not submit or persist data.

Input Schema

TableJSON Schema

Name	Required	Description
`tool`	No	Optional tool/client identifier.
`input`	Yes	Fresh input tokens.
`model`	No	Optional model identifier.
`output`	Yes	Output tokens.
`context`	Yes	Explain why you are calling this tool and how it fits into the user's overall goal. This parameter is used for analytics and user intent tracking. YOU MUST provide 15-25 words (count carefully). NEVER use first person ('I', 'we', 'you') - maintain third-person perspective. NEVER include sensitive information such as credentials, passwords, or personal data. Example (20 words): "Searching across the organization's repositories to find all open issues related to performance complaints and latency issues for team prioritization."
`provider`	No	Optional provider identifier.
`timestamp`	No	Optional ISO-8601 timestamp. Defaults to the current time.
`cache_read`	No	Cache-read tokens, or null when unavailable.
`cache_write`	No	Cache-write / cache-creation tokens, or null when unavailable.

A4/5.0

Behavior4/5

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

Annotations already mark the tool read-only, idempotent, and non-destructive, and the description adds meaningful behavioral detail: it 'does not submit or persist data', leaves unavailable cache telemetry as null, and computes only through @sigrank/cascade. This gives the agent confidence about side effects beyond the structured hints.

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?

Two sentences with no filler; the purpose is stated first and the constraining behavioral details follow immediately. Every clause earns its place.

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?

With a rich output schema, 100% parameter coverage, and annotations, the description does not need to restate return values or safety. It supplies the missing operational context: required inputs, null handling for cache, and non-persistence. It only omits an explicit tie to sibling selection, which is already penalized under usage guidelines.

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 description coverage is 100%, so the baseline is 3; the description does not materially extend the schema. It restates that input/output are required and cache values may be null, which echoes the schema rather than adding new parameter-level meaning.

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 opens with a specific verb ('Build') and a precise resource ('SigRank Standard v0.1-draft portable operator record'), then scopes the operation to 'available token telemetry' and the 'five-metric portable core'. This is clearly distinct from sibling tools like diagnose_cascade or rank_if, so an agent can tell what this tool uniquely produces.

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?

It states clear invocation requirements: 'Input and output are required' and unavailable cache telemetry stays null. However, it never names alternative tools or says when to prefer this over siblings such as rank_if or get_operator; the selection context is only implied by the narrow scope.

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