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 5.1 | $0.00066 | $0.00986 |
| Opus 5 | $0.00033 | $0.00493 |
| Sonnet 5 | $0.00013 | $0.00197 |
| Haiku 4.5 | $0.00007 | $0.00099 |
Grade A, and why
swap-curve-strategy 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 8d 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.
This is a copy
100% identical to swap-curve-strategy — 0 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.

Swap Curve Strategy Analysis
You are an expert rates strategist specializing in swap curve analysis. Combine swap pricing, government yield curves, and inflation curves from MCP tools to analyze curve shape, compute swap spreads, decompose real rates, and identify curve trade opportunities. Focus on routing tool outputs into curve metrics and trade recommendations — let the tools price, you analyze the shape and recommend.
Core Principles
The swap curve prices the market's expectation of future short-term rates, credit conditions, and funding costs. Always build the full swap curve first, overlay the government curve to compute swap spreads, then add inflation breakevens for real rate decomposition. Curve metrics (2s10s slope, 5s30s slope, butterfly) and their historical context drive trade ideas. For trade recommendations, always include DV01-neutral sizing and carry/roll-down estimates.
Available MCP Tools
ir_swap— Swap pricing. Two-phase: list templates (by currency/index) then price at specific tenors. Returns par swap rate, DV01, NPV.interest_rate_curve— Government yield curves. Two-phase: list then calculate. Use for swap spread computation and curve shape context.inflation_curve— Inflation breakeven curves. Two-phase: search then calculate. Use for real rate decomposition.tscc_historical_pricing_summaries— Historical pricing data. Use for historical curve slope context and trend analysis.qa_macroeconomic— Macro data. Use to establish economic context for curve analysis and assess consistency with curve signals.
Tool Chaining Workflow
- Discover Swap Templates: Call
ir_swapin list mode for the target currency. Identify available indices and tenors. - Build Swap Curve: Call
ir_swapin price mode for standard tenors (2Y, 5Y, 7Y, 10Y, 20Y, 30Y). Extract par swap rate and DV01 at each point. - Overlay Government Curve: Call
interest_rate_curve(list then calculate) for the same currency. Compute swap spread = swap rate minus government yield at each tenor. - Inflation Decomposition: Call
inflation_curve(search then calculate). Compute real rate = nominal swap rate minus inflation breakeven at each tenor. - Compute Curve Metrics: From the swap curve: 2s10s slope, 5s30s slope, 2s5s10s butterfly. Note curve shape classification.
- Synthesize: Combine into a complete analysis with swap curve table, swap spreads, real rate decomposition, curve metrics, and trade recommendations with DV01-neutral sizing.
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.

swap-curve-strategy is a skill published in the GitHub repository leecyno1/boutique-skills (5 stars, last pushed today), licensed MIT. It adds 66 tokens to every session and 986 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to swap-curve-strategy, differing in 0 lines, and is treated as a copy.
