DeltaSignal ATLAS-7

DeltaSignal peer ranking

deltasignal_peer_ranking

Read-onlyIdempotent

Use this read-only tool to compare one crypto public company against its current peer group. It returns peer rank, peer percentile, peer score, stressed leverage, risk tier, debt coverage, quality flags, linkbase provenance, and period/source-date context. Parameters: ticker is required and must be one public-company symbol such as COIN, MSTR, MARA, RIOT, HUT, or CLSK; period is optional and only for reproducing a known filing date. Behavior: read-only and idempotent; it performs one HTTPS read, has no destructive side effects, and does not write external systems or access user accounts. Use it when the user asks whether one issuer is better or worse than peers; use covenant_stress for absolute stress, top_stressed for universe-wide ranking, and alpha_signals for opportunity signals.

TDQS

A5/5.0

Behavior5/5

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

Annotations already declare readOnlyHint=true and idempotentHint=true, but the description goes further by adding concrete behavioral details: 'performs one HTTPS read, has no destructive side effects, and does not write external systems or access user accounts.' This exceeds what annotations alone convey.

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 lists outputs, parameters, behavior, and usage guidance in a logical sequence. No filler or repetition; every sentence adds value and the length is proportionate to the tool's complexity.

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 covers purpose, outputs, parameters, behavioral guarantees, and usage alternatives, making it self-sufficient for an agent. With a rich output schema and annotations already present, the description fully contextualizes when and how to invoke the tool.

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

Parameters5/5

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

Schema coverage is 100%, so baseline is 3, but the description adds meaning beyond the schema: it clarifies that ticker must be a public-company symbol and provides concrete examples, and states that period is 'only for reproducing a known filing date,' enriching the schema's descriptions.

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: 'compare one crypto public company against its current peer group,' and enumerates the exact output fields (peer rank, peer percentile, peer score, etc.), clearly distinguishing it from sibling tools like covenant_stress and top_stressed.

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?

Explicit usage guidance is provided: 'Use it when the user asks whether one issuer is better or worse than peers,' and it names three alternatives with their purposes ('covenant_stress for absolute stress, top_stressed for universe-wide ranking, alpha_signals for opportunity signals'). This is textbook when-to-use and when-not-to-use.

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