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 canonical pre-flight per 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 — carry the _run_id from your first tool result and name yourself (and your parent, if you were spawned).

| ratio_categories | all | profitability, liquidity, leverage, efficiency, valuation, growth |
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:
- Executive Summary — headline conclusions (≤200 words).
- Core analysis sections — per this skill's methodology and analyst modes.
- Data classification — tag findings
[FACT]/[DEDUCTED]/[VIEW]percontracts/snapshot-synthesis.md. - Coverage Gaps & Citations — inline
/v/citations are PRIMARY (immediately after each fact); the bottom Citations section is a non-duplicative roll-up index. - 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) percontracts/output-frontmatter-schema.md. - Snapshot synthesis: after writing the deliverable, update the two-tier snapshot and classify findings as
[FACT]/[DEDUCTED]/[VIEW]— seecontracts/snapshot-synthesis.md. - Session archival: record the run under
sessions/{YYYY-MM-DD}/and updatesessions/INDEX.mdpercontracts/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.
Error Handling
| Failure Mode | Detection | Action | User-Facing Message |
|---|---|---|---|
| Missing data | XBRL returns empty for key concepts | Widen date range and retry once | "No financial data available for {ticker} in requested window." |
| Non-USD currency | unit field is not USD | Annotate with ISO 4217 code | "⚠ {ticker} reports in {currency}. Ratios computed in reporting currency." |
| Peer data incomplete | <3 peers have comparable data | Reduce peer set; flag incomplete peers | "Cross-company comparison based on {n} of {m} peers with complete data." |
| MCP unreachable | Preflight probe fails | Halt with actionable error | "agentii data plane unreachable; check connection." |
