Ratio Analysis

Financial Ratio Analysis

Quantitative skill computing 6 categories of financial ratios from XBRL financial data. Cross-company comparison within sector. References professional financial training ratio interpretation standards.

Preflight

Run the canonical pre-flight sequence — MCP health probe, ticker resolution, workspace style.md override, memory load, and coverage check. See contracts/preflight.md.

**get_realtime_quote availability **: If get_realtime_quote is not yet deployed in the MCP surface, use search_earnings_calendar for PE/earnings data and flag valuation ratios as "current price unavailable — using latest reported data." Prompts user for current stock price as manual fallback.

Include the X-Agentii-Trace header on every tool call per contracts/x-agentii-trace-header.md.

Methodology

Retrieval Scope

structured_only — this skill computes ratios from XBRL financial data and real-time price data. No unstructured document search required. All data sources are queryable via agentii MCP tools.

Retrieval Strategy

See contracts/retrieval.md for the canonical decision tree; skill-specific retrieval detail is in references/methodology.md.

Temporal Scope

Default: 4 fiscal quarters (max 12). Ratio analysis uses trailing 4 quarters for current snapshot; up to 12 quarters for trend analysis.

Tool Allowlist

See frontmatter allowed_tools. search_xbrl_facts is the primary data source for financial statement line items. get_realtime_quote provides current stock price for valuation ratios (P/E, P/B, P/S). search_companies enables peer identification for cross-company comparison.

Protocol

Step-by-step execution detail is in references/methodology.md.

ROIC Analysis: When computing Return on Invested Capital, apply the institutional-grade framework in references/roic-methodology.md. Use the four-variant approach (excluding/including goodwill × with/without intangible capitalization) appropriate to the analytical question, industry-specific capitalization rates per the academic framework, ROIIC over rolling 3-year periods, and DuPont decomposition to map ROIC to competitive strategy. Is the company passing the one dollar test?

Ratio Definitions

Full ratio formula definitions are in references/methodology.md.

Output File

Write the final deliverable to {ticker}/{YYYY-MM-DD_HHMM}_ratio-analysis_{affix}.md . Example affixes: profitability, liquidity-leverage, peer-comparison.

Output Structure

The deliverable is a structured markdown report written to the path in ## Output File. Full section-by-section template (headings, tables, and field definitions) lives in references/output-structure.md. Required elements:

1. Executive Summary — headline conclusions (≤200 words).
2. Core analysis sections — per this skill's methodology and analyst modes.
3. Data classification — tag findings [FACT] / [DEDUCTED] / [VIEW] per contracts/snapshot-synthesis.md.
4. Coverage Gaps & Citations — inline /v/ citations are PRIMARY (immediately after each fact); the bottom Citations section is a non-duplicative roll-up index.
5. Output frontmatter — emit the FR-090 structured block per contracts/output-frontmatter-schema.md.

Citations & memory: follow contracts/citation-and-memory.md — ≥1 citation per 200 words; every material fact, table row, and metric is immediately followed by its inline clickable https://agentii.ai/v/{ticker}/{citation_id}/{N} link; a bottom Citations section provides a non-duplicative roll-up index; the closing TUI reply includes a compact Key Citations list (headline 5–10 facts) of clickable /v/ URLs; and append the run to agentii.md per contracts/agentii-md-schema.md.

Tool Fallbacks

Per-tool failure modes and fallback actions are tabulated in references/tool-fallbacks.md.

Memory & Snapshot

• Memory load (pre-flight): load prior workspace context for the ticker before retrieval — see contracts/memory-load.md.
• Structured output frontmatter: emit the FR-090 block (key_metrics, conclusions, facts_count, deducted_count, views_count, citation_count) per contracts/output-frontmatter-schema.md.
• Snapshot synthesis: after writing the deliverable, update the two-tier snapshot and classify findings as [FACT]/[DEDUCTED]/[VIEW] — see contracts/snapshot-synthesis.md.
• Session archival: record the run under sessions/{YYYY-MM-DD}/ and update sessions/INDEX.md per contracts/session-format.md.

Final Summary (TUI)

End the closing chat reply with a compact Key Citations list (headline 5–10 facts), each a clickable https://agentii.ai/v/{ticker}/{citation_id}/{N} link, so the user can cmd+click straight to the exact SEC page. See contracts/citation-and-memory.md.
