SEC company financials

blackwood_sec_facts
Read-onlyIdempotent

Use when you need sec filings company financials, earnings or fundamentals for a stock ticker for the last two fiscal years. Do not use for quarterly numbers, real-time prices, non-US companies or filings older than two years. Returns JSON with a US-listed company's annual revenue, net and operating income, diluted EPS, operating cash flow and year-end balance sheet from SEC filings for 0.02 USDC per call. Typical response time 300 ms (p95). Category: Data.

TDQS

A4.4/5.0
Behavior4/5

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

Annotations already cover safety (readOnly, idempotent, non-destructive, closed-world), and the description adds genuine context beyond them: 0.02 USDC cost per call, ~300 ms p95 latency, and the exact data vintage (annual, last two fiscal years). It does not mention rate limits or failure modes, but the safety profile is well covered.

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?

Front-loaded with the use case and exclusions, then return contents, pricing and latency; every sentence carries information. The trailing 'Category: Data.' is low-value boilerplate but costs little.

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?

For a two-parameter read with a full output schema, the description supplies everything an agent needs to decide and call: scope, exclusions, cost, latency and the returned metric set. No gaps remain.

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 coverage is 100% and the ticker description already notes 'a company that files with the SEC, e.g. AAPL', so the description's US-listed/two-year framing adds only marginal meaning. The response_format enum is fully explained in the schema, not the description, so baseline 3 applies.

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?

States a specific verb and resource (SEC filings company financials) plus the scope constraint (last two fiscal years, US-listed tickers), and the sibling list contains no overlapping data source, so an agent can route to it unambiguously.

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?

Explicitly names when to use it and four when-not conditions (quarterly numbers, real-time prices, non-US companies, filings older than two years). No competing sibling exists, so no named alternative is required.

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