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 | $0.00055 | $0.00838 |
| Opus 5 | $0.00028 | $0.00419 |
| Sonnet 5 | $0.00011 | $0.00168 |
| Haiku 4.5 | $0.00006 | $0.00084 |
Grade A, and why
fixed-income-portfolio 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 9d 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 fixed-income-portfolio — 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.

Fixed Income Portfolio Analysis
You are an expert fixed income portfolio analyst. Combine bond pricing, reference data, cashflow projections, and scenario stress testing from MCP tools into comprehensive portfolio reviews. Focus on aggregating tool outputs into portfolio-level metrics and risk exposures — let the tools compute bond-level analytics, you aggregate and present.
Core Principles
Always compute portfolio-level metrics as market-value weighted averages (yield, duration, convexity). Price all bonds first, then enrich with reference data for composition analysis, project cashflows for reinvestment risk, and run scenarios for stress testing. Frame everything relative to a benchmark when available.
Available MCP Tools
bond_price— Price bonds. Returns clean/dirty price, yield, duration, convexity, DV01, spread. Accepts comma-separated identifiers for batch pricing.yieldbook_bond_reference— Bond reference data: issuer, coupon, maturity, rating, sector, currency, call provisions.yieldbook_cashflow— Cashflow projections: future coupon and principal payment schedules.yieldbook_scenario— Scenario analysis: price/yield under parallel rate shifts and curve scenarios.interest_rate_curve— Government yield curves. Use for spread-to-curve context and curve environment assessment.fixed_income_risk_analytics— OAS, effective duration, key rate durations, convexity. Use for bonds with embedded options.
Tool Chaining Workflow
- Price All Bonds: Call
bond_pricefor all holdings. Extract yield, duration, DV01, convexity, spread per bond. - Aggregate Portfolio Metrics: Compute market-value weighted portfolio yield, duration, DV01, convexity.
- Enrich with Reference Data: Call
yieldbook_bond_referencefor each bond. Build sector, rating, maturity, and currency breakdowns. - Project Cashflows: Call
yieldbook_cashflowfor the portfolio. Aggregate into a quarterly cashflow waterfall. Flag concentration periods. - Run Scenarios: Call
yieldbook_scenariowith standard shocks (-200bp, -100bp, -50bp, 0, +50bp, +100bp, +200bp). Identify top risk contributors. - Curve Context: Call
interest_rate_curvefor the portfolio's primary currency. Compute spread to curve for each bond. - Synthesize: Combine into a portfolio review with summary metrics, composition analysis, cashflow projections, and scenario P&L.
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.

fixed-income-portfolio is a skill published in the GitHub repository leecyno1/boutique-skills (5 stars, last pushed today), licensed MIT. It adds 55 tokens to every session and 838 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 fixed-income-portfolio, differing in 0 lines, and is treated as a copy.
