Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.02315 |
| Opus 5 | $0.00000 | $0.01157 |
| Sonnet 5 | $0.00000 | $0.00463 |
| Haiku 4.5 | $0.00000 | $0.00231 |
Grade A, and why
basel-iii 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Basel III/IV Framework
Capital requirements, liquidity ratios, leverage — comprehensive Basel regulatory framework for banking supervision.
When to Activate
- Capital adequacy calculations (CET1, Tier 1, Total Capital)
- Risk-weighted asset computation (credit, market, operational risk)
- Liquidity ratio analysis (LCR, NSFR)
- Leverage ratio assessment
- Capital buffer requirements
- FRTB (Fundamental Review of the Trading Book) implementation
- Basel IV output floor impact analysis
- Regulatory capital planning and stress testing
Core Concepts
Capital Structure
Common Equity Tier 1 (CET1) — highest quality:
- Common shares, retained earnings, accumulated OCI (with adjustments)
- Deductions: goodwill, intangible assets, deferred tax assets (threshold), investments in financial institutions
- Minimum requirement: 4.5% of RWA
Additional Tier 1 (AT1):
- Perpetual instruments with loss-absorption features (CoCos — contingent convertibles)
- Write-down or conversion trigger at CET1 ratio of 5.125% (or higher)
- AT1 + CET1 minimum: 6.0% of RWA
Tier 2 Capital:
- Subordinated debt (minimum 5-year original maturity, amortized in last 5 years)
- Eligible provisions (up to limit)
- Total Capital minimum: 8.0% of RWA
Capital Requirements Summary
Minimum + Conservation + Countercyclical + G-SIB
CET1 4.5% 7.0% 7.0-9.5% 8.0-10.5%
Tier 1 6.0% 8.5% 8.5-11.0% 9.5-12.0%
Total Capital 8.0% 10.5% 10.5-13.0% 11.5-14.0%
Capital Buffers
| Buffer | Size | Trigger | Effect when breached |
|---|---|---|---|
| Conservation buffer | 2.5% CET1 | Always on | Restrictions on dividends, buybacks, bonuses |
| Countercyclical buffer | 0-2.5% CET1 | Set by national authority based on credit cycle | Restrictions on distributions |
| G-SIB surcharge | 1.0-3.5% CET1 | Systemically important banks (buckets 1-5) | Restrictions on distributions |
| D-SIB surcharge | Varies | National authority designation | Restrictions on distributions |
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.

basel-iii is a skill published in the GitHub repository brainbytes-dev/everything-claude-finance (5 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,315 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
