Valuein — SEC EDGAR Fundamentals & Smart-Money Data

Forensic Audit (Beneish + Sloan + Solvency)

forensic_audit
Read-onlyIdempotent

Deterministic forensic-accounting scores for a single ticker: partial Beneish M-Score, Sloan accruals, and a solvency snapshot. Returns a red-flag narrative ranked by severity, with citations to source filings. Used by the forensic_earnings_brief SOP.

Note: full Beneish needs AR / current assets / PPE / SGA / current liabilities, which aren't in our fundamentals model. We compute the recoverable subset (SGI + TATA + LVGI) and flag partial=true. Tier: sp500+.

It is a floor for a single filer, not a ceiling: a filer with a live partition receives its filing, facts and ratios intraday (minutes after EDGAR dissemination), so an entity-scoped read may carry a filing newer than this; cross-sectional ranks (factor scores, earnings signals) refresh with the weekly bulk export."

TDQS

A4.1/5.0
Behavior5/5

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

It discloses substantive behavioral traits beyond the annotations: the tool is deterministic, computes only a recoverable subset of the full Beneish M-Score, flags `partial=true`, and returns a severity-ranked red-flag narrative with citations to source filings. This is genuinely useful context that annotations alone do not provide.

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 tight and front-loaded with the core function, then adds a concise and highly relevant limitation note. Every sentence adds value, and the structure clearly separates main behavior from constraints.

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 one well-documented parameter, an output schema, and annotations covering read-only/idempotent behavior, the description provides all essential additional context: return type, limitation, partialness flag, tier restriction, and intended SOP association. Nothing critical appears missing.

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% for the single `ticker` parameter, including examples and constraints. The description adds only 'single ticker' and 'Tier: sp500+', which are helpful but do not materially enhance understanding of the parameter beyond the schema.

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

Purpose4/5

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

The description states a specific action and resource: 'Deterministic forensic-accounting scores for a single ticker' covering Beneish M-Score, Sloan accruals, and solvency. It clearly lists outputs, but it does not explicitly differentiate itself from sibling analytical tools or name alternatives, so it stops short of full sibling differentiation.

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?

The description implies usage through 'Used by the forensic_earnings_brief SOP' and explains the partial computation context. However, it does not explicitly state when to choose this tool over alternatives, nor does it enumerate exclusion conditions or clearly define the expected use case for an autonomous agent.

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