What it does

Quantitative Screening is an agent skill from agentii-ai/agentii-investment-intelligence. Quantitative stock screening, forward-looking valuation outlier detection, backward-looking financial statement validation, PEG ratio analysis, earnings growth profile assessment, turnaround vs value trap discrimination, data mining bias prevention

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/modes.md`, `references/multi-factor-screening-methodology.md` and `references/quant-methodology.md`).

It sits in Business, Finance & HR, covering Financial analysis and Data cleaning. The repository describes itself as: Claude-type skills for institutional equity research — 25 AI agent skills with SEC filings, XBRL financials, earnings calendars, DCF/comps/LBO models, and PPT generation. Powered… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Financial analysis
  • Tasks that involve Data cleaning

Example prompts

  • “/quantitative-screening”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Quantitative methodology — references/quant-methodology.md (bundled screening framework)
  2. Financial data — SEC XBRL facts via agentii MCP for historical financials
  3. Market data — ~~market_data placeholder for real-time valuation multiples
  4. Strategy frameworks — search_investment_strategies(domain=fundamental, kind=screening)

What it can do on your machine

Read from SKILL.md and the folder at commit 86980e1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Quantitative Screening loads about 1.9k tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 68 tokens; SKILL.md has 778 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~12k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Preflight

Run canonical pre-flight per contracts/preflight.md. Include the X-Agentii-Trace header on every tool call per contracts/x-agentii-trace-header.md — carry the _run_id from your first tool result and name yourself (and your parent, if you were spawned).

Data Source Priority

  1. Quantitative methodology — references/quant-methodology.md (bundled screening framework)
  2. Financial data — SEC XBRL facts via agentii MCP for historical financials
  3. Market data — ~~market_data placeholder for real-time valuation multiples
  4. Strategy frameworks — search_investment_strategies(domain=fundamental, kind=screening)

Methodology

Retrieval Scope

structured_only

Retrieval Strategy

Ownership & insider signals: search_institutional_holdings (top-10 holders + whale portfolios, direction=accumulating|reducing|new|exited) and search_insider_trades (Form-4 transactions with SEC URLs) are available as signal inputs.

Branch (a) Structured Data Query from contracts/retrieval.md: primary retrieval via XBRL facts for financial statement data. Supplement with search_investment_strategies for screening methodology validation. Detailed methodology in references/quant-methodology.md.

Protocol

This skill implements a two-directional screening process: forward-looking valuation discovery and backward-looking financial statement validation. Core principle: the market is mostly efficient. An outlier exists because either the market is wrong (your edge) or you are missing something. Non-participation is always an option.

Detailed methodology: peer selection protocol, turnaround financial scorecard, 7-step sector cleaning, and data mining bias catalog are in references/quant-methodology.md.

Foundational principle: P/E measures what the market is willing to pay for forward earnings — it is a market psychology metric, not intrinsic value. "Cheap" and "expensive" are not analytical conclusions. The question is: why has the market assigned this multiple? PEG < 1.0 is not a universal buy signal — calibrate sector-relatively, growth-rate-adjust, and cross-check with EV/EBITDA-to-Growth. This skill uses PEG as a screening filter only; for a standalone PEG-based valuation, defer to the peg-valuation skill.

Steps
  1. Universe and Macro Filter: Apply portfolio bias from orchestrator. Long → $3B-$10B mid-caps. Short → $20B+ large caps. Neutral → both, emphasize pairs. Weight sectors by macro regime preferences.

  2. Forward-Looking Valuation Scan: Screen using four-pillar framework (PE1, PE2; EG1, EG2; PEG1, PEG2; revenue multiples). Rank by deviation from sector median. Top/bottom decile advance. Calibrate PEG sector-relatively. Use EV/EBITDA-to-Growth as cross-check; prefer EBIT over EBITDA for capital-intensive sectors.

  3. Backward-Looking Financial Validation (execute in this order):

    • Revenue: growth trajectory, organic vs. acquisition quality, concentration risk
    • Earnings quality: GAAP vs. non-GAAP (> 20% gap = investigate), SBC > 10% revenue = red flag, "non-recurring" in 3+ of 4 quarters = recurring
    • Margin: gross margin trend, incremental margins (> 50% strong, < 20% weak)
    • Cash flow: FCF/Net Income conversion. > 80% excellent, 70-80% acceptable, 50-70% explain, < 50% hard stop for longs. DSO + inventory both rising = channel stuffing risk.
  4. Peer Selection (dual-path): Sector path (GICS → 10-K competition → sell-side → merger docs) + Fundamentals path (cluster by growth, margins, ROIC). Must converge on 4-6 names. Divergence = classification error. Use median. For a formal benchmarked peer set, hand off to peer-bench; for full multiple spreading and calendarization, hand off to comps — do not rebuild either here.

  5. Growth Profile and Trap Detection: EPS CAGR 3-5yr (consistency > magnitude). Estimate trajectory: rising + rising = aligned; falling + rising = danger. Beat/raise = strongest signal. Decompose growth source (revenue vs. cost-cutting vs. buybacks). Turnaround scorecard (0-10): 7-10 investigate long, 0-3 avoid/short. Exclude revenue-growth stories from turnaround classification. Scan for data mining biases.

  6. Sector Cleaning (when data errors suspected): Apply 7-step protocol from reference. Only clean < 20 candidates that pass initial screen.

  7. Output: Score each candidate (valuation × validation × growth). Flag GREEN/AMBER/RED. Handoff: ranked list, peer data, turnaround scores, data quality flags.
