DeltaSignal ATLAS-7

DeltaSignal company fundamentals

deltasignal_company_fundamentals

Read-onlyIdempotent

Use this read-only tool to retrieve SEC XBRL-backed fundamentals for one crypto public company ticker. It returns filing period, entity identifiers, filing form, core financial values, provenance, and optional segment or related-party containers when requested. Parameters: ticker is required; period is optional YYYY-MM-DD; include_segments and include_related_party request additional containers when available and otherwise return availability metadata. Behavior: read-only and idempotent; it performs one HTTPS read, has no destructive side effects, and does not modify SEC data, accounts, files, or wallets. Use it when the user asks for revenue, net income, assets, cash, liabilities, equity, SEC filing context, or fact provenance; use alpha_signals or covenant_stress for modeled signal interpretation.

Input Schema

TableJSON Schema

Name	Required	Description
`period`	No	Optional YYYY-MM-DD reporting period. Omit for the latest available filing period.
`ticker`	Yes	Required crypto public company ticker. Examples: COIN, MSTR, MARA, RIOT, HUT, CLSK.
`include_segments`	No	Request segment fact container when available. Current runtime returns availability metadata even when segment facts are not populated.
`include_related_party`	No	Request related-party transaction container when available. Current runtime returns availability metadata even when related-party facts are not populated.

Output Schema

TableJSON Schema

Name	Required	Description
`data`	Yes	SEC XBRL-backed fundamentals for one crypto public company ticker.
`provenance`	Yes	Traceability information for the MCP tool response.
`mcp_summary`	Yes	Concise high-signal summary of the tool response. Maximum 140 characters.
`usage_metadata`	No	Performance and estimated cost metadata for this MCP tool call.
`suggested_follow_ups`	Yes	Concrete next MCP calls an agent can run to continue the workflow.

TDQS

A4.4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, but the description adds valuable specificity: it 'performs one HTTPS read, has no destructive side effects, and does not modify SEC data, accounts, files, or wallets.' It also clarifies that optional containers return availability metadata when facts are not populated, which is useful behavioral context. No contradiction with annotations.

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

Conciseness4/5

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

The description is organized into clear, purposeful sentences: purpose, returned content, parameters, behavior, and usage guidance. It is front-loaded with the main action and avoids fluff. Though slightly longer than minimal, each sentence contributes meaningful information, so it earns a 4 rather than a 5.

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 presence of a comprehensive output schema, detailed parameter descriptions, and a simple read-only tool, the description is complete. It covers what data is returned, when to use the tool, optional parameter behavior, safety guarantees, and directs to alternatives for different use cases. No critical missing context.

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%, with detailed descriptions and examples for all four parameters. The description summarizes parameter roles (e.g., 'ticker is required; period is optional YYYY-MM-DD; include_segments and include_related_party request additional containers') but largely restates schema information without adding new semantic value. Baseline of 3 is appropriate.

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 it 'retrieve[s] SEC XBRL-backed fundamentals for one crypto public company ticker,' specifying the exact verb, resource, and scope. It also explicitly lists the returned content (filing period, identifiers, filing form, core financial values, provenance) and distinguishes itself from modeled signal tools by indicating 'alpha_signals or covenant_stress' for those use cases.

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 for revenue, net income, assets, cash, liabilities, equity, SEC filing context, or fact provenance; use alpha_signals or covenant_stress for modeled signal interpretation.' This clearly states when to use this tool and names specific alternative tools, leaving no ambiguity.

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