Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

design-finance-report scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

84% identical to finance-report — 29 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Finance Report Skill

Produce a single-screen financial report in one self-contained HTML file.

Workflow

  1. Read the active DESIGN.md. Tables, KPI cards, and chart strokes use palette tokens — never invent new ones.
  2. Classify the period (monthly / quarterly / yearly) and entity (startup, division, project) from the brief. If unspecified, assume a quarterly SaaS report and pick believable numbers.
  3. Layout the page in this order:
    • Masthead: company / period / "Confidential — Finance" badge.
    • Headline KPI strip (4 cards): Revenue, Net new MRR, Gross margin, Cash runway.
    • Revenue trend chart (inline SVG line + area).
    • Cost breakdown chart (inline SVG bar) with a 2–3 bullet caption.
    • P&L summary table (Revenue / Gross profit / Opex / Net) with current vs prior period.
    • Top accounts table with logo placeholders, plan, ARR, status badge.
    • Outlook paragraph + footer with author + signature line.
  4. Write one self-contained HTML doc (CSS in one inline <style> block).
  5. Self-check: every number ties to a labelled chart or table; deltas show direction and percentage; accent colour used at most twice.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
