DeltaSignal ATLAS-7

DeltaSignal top stressed issuers

deltasignal_top_stressed

Read-onlyIdempotent

Use this read-only screening tool to rank the most stressed crypto public companies in the active DeltaSignal slice. It returns issuer rows sorted by stress, including ticker, period, risk tier, stress values, debt-coverage status, quality flags, linkbase provenance, live-price indicators, and pagination metadata. Parameters: limit is 1-100 and should usually be 5-20 for summaries; offset is only for pagination after a previous screen. Behavior: read-only and idempotent; it performs one HTTPS read, has no destructive side effects, and never writes orders, files, accounts, or wallet state. Use it for portfolio triage, issuer watchlists, and deciding which companies deserve deeper covenant or alpha analysis; use covenant_stress with ticker for detail on one issuer.

TDQS

A4.7/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint false. The description adds concrete behavioral detail: 'performs one HTTPS read, has no destructive side effects, and never writes orders, files, accounts, or wallet state.' This goes beyond the annotation flags, though it does not disclose any extra edge cases such as rate limits or data freshness, keeping it a notch below a 5.

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 front-loaded with the core purpose, then return contents, parameters, behavior, and use cases. Every sentence carries distinct information and there is no filler or repetition. It is compact yet comprehensive.

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?

Given the tool has an output schema, the description does not need to explain return types but still lists key output fields. It covers purpose, expected parameter ranges, side-effect behavior, and alternatives. The presence of a clear sibling alternative and explicit usage context makes this fully complete for an agent to select and invoke correctly.

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

Parameters4/5

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

Schema coverage is 100% with parameter descriptions, so the baseline is 3. The description adds value by recommending 'limit is 1-100 and should usually be 5-20 for summaries' and clarifying that offset is 'only for pagination after a previous screen,' which provides practical guidance beyond the raw schema constraints.

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 and resource: 'rank the most stressed crypto public companies in the active DeltaSignal slice.' It also details the output row contents (ticker, period, risk tier, stress values, etc.) and distinguishes itself from the sibling covenant_stress tool by noting it is for screening while covenant_stress is for single-issuer detail.

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?

It explicitly states use cases: 'portfolio triage, issuer watchlists, and deciding which companies deserve deeper covenant or alpha analysis.' It also gives an alternative: 'use covenant_stress with ticker for detail on one issuer,' plus parameter guidance for limit and offset. This meets the highest bar for when and when-not guidance.

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