update

Update existing coverage for the company specified by the user: $ARGUMENTS

Before starting, read ../data-access.md for data access methods and ../design-system.md for formatting conventions. Follow the data access detection logic and design system throughout this skill.

This skill refreshes existing deliverables with the latest quarterly data, highlights what changed, and re-renders both outputs.

Phase 1 — Load Existing Context

Check for existing context files in reports/.tmp/:

• reports/.tmp/{TICKER}_context.json (research note context)
• reports/.tmp/{TICKER}_model_context.json (model context)

If neither exists, tell the user: "No existing coverage found for {TICKER}. Run /initiate {TICKER} first to create initial coverage." and stop.

Read the existing context(s) to understand what periods and data were previously gathered.

Phase 2 — Identify New Data

Look up the company using discover_companies. Capture company_id, latest_calendar_quarter (anchor for all period calculations — see ../data-access.md Section 1.5), and latest_fiscal_quarter. Note the firm name for report attribution (default: "Daloopa") — see ../data-access.md Section 4.5. Compare to the periods in existing context. Determine which new quarters need to be pulled.

If no new quarters are available, tell the user: "Coverage is already current through {latest_period}. No new data to update." and stop.

Phase 3 — Pull Fresh Data

Pull data for ALL periods (not just new ones) to ensure consistency:

• Full Income Statement, Balance Sheet, Cash Flow
• Segments, KPIs, Guidance
• Share count, buyback activity

This refreshes the entire dataset, catching any Daloopa revisions to prior quarters.

Phase 4 — Market Data Refresh

Get current prices, trading multiples, and risk-free rate (see ../data-access.md Section 2).

Also refresh peer multiples if comps data exists in context.

Phase 5 — Re-run Projections

With updated historical data, re-run projections. If a projection engine is available (see ../data-access.md Section 5), use it. Otherwise project manually.

Phase 6 — Diff Analysis

Save the new context alongside the old:

• Write new context to reports/.tmp/{TICKER}_context_new.json
• Run: python infra/report_differ.py --old reports/.tmp/{TICKER}_context.json --new reports/.tmp/{TICKER}_context_new.json --output reports/.tmp/{TICKER}_diff.json
• Read the diff to understand what changed

Key changes to highlight:

• Revenue/EPS beats or misses vs prior estimates
• Margin changes (expansion or compression)
• Guidance changes (raised, lowered, maintained)
• New KPI data points
• Share count changes (buyback acceleration/deceleration)
• Valuation changes (price moved, multiples shifted)

Phase 7 — Update Qualitative Sections

Search filings for the new quarter(s):

• Earnings highlights and management commentary
• Updated guidance language
• New risk factors or strategic shifts
• Update investment thesis if data warrants it

Revise the executive summary and key findings to reflect the latest quarter.

Phase 8 — Re-render Outputs

Update charts with new data points, then re-render:

Research Note:

1. Overwrite context: reports/.tmp/{TICKER}_context.json
2. Re-generate charts with updated data
3. Run: python infra/docx_renderer.py --template templates/research_note.docx --context reports/.tmp/{TICKER}_context.json --output reports/{TICKER}_research_note.docx

Excel Model:

1. Overwrite context: reports/.tmp/{TICKER}_model_context.json
2. Run: python infra/excel_builder.py --context reports/.tmp/{TICKER}_model_context.json --output reports/{TICKER}_model.xlsx

Phase 9 — Change Summary

Present a clear summary of changes to the user:

## {TICKER} Coverage Update — {new_quarter} Added

### Key Changes
- Revenue: $XX.XB vs $XX.XB prior quarter (+X.X% QoQ, +X.X% YoY)
- EPS: $X.XX vs $X.XX guidance (beat/miss by X.X%)
- Gross Margin: XX.X% vs XX.X% prior quarter (+/- XXbps)
- {other notable changes}

### Projection Updates
- {what changed in forward estimates and why}

### Valuation Impact
- DCF implied price: $XXX (was $XXX, change of +/-X%)
- Comps implied range: $XXX - $XXX

### Files Updated
- Research note: reports/{TICKER}_research_note.docx
- Excel model: reports/{TICKER}_model.xlsx
- Diff report: reports/.tmp/{TICKER}_diff.json

All financial figures must use Daloopa citation format: $X.XX million
