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 | $0.00043 | $0.02088 |
| Opus 5 | $0.00022 | $0.01044 |
| Sonnet 5 | $0.00009 | $0.00418 |
| Haiku 4.5 | $0.00004 | $0.00209 |
Grade A, and why
risk 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 12d 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.

Risk Analysis
Explore risk characteristics and position sizing metrics for trading strategies.
Prerequisites
- TradeBlocks MCP server running
- Block with trade data (10+ trades minimum for meaningful metrics)
Process
Step 1: Understand User Goals
Risk analysis serves different purposes. Ask what the user wants to understand:
| Goal | Primary Tool | Also Consider |
|---|---|---|
| "What does Kelly suggest?" | get_position_sizing |
Monte Carlo for drawdown context |
| "What are worst-case scenarios?" | run_monte_carlo |
stress_test for named scenarios |
| "How did I do during COVID/bear markets?" | stress_test |
Drawdown attribution |
| "What caused my biggest drawdown?" | drawdown_attribution |
Tail risk for future risk |
| "How correlated are my strategies?" | get_tail_risk |
Position sizing per strategy |
| "What if I change allocations?" | what_if_scaling |
Marginal contribution |
Ask: "What aspect of risk would you like to explore?"
Then use list_blocks to identify the target block.
Step 2: Position Sizing (Kelly Criterion)
Call get_position_sizing with the user's capital base.
Key parameters:
capitalBase: Starting capital (required)kellyFraction: "full", "half" (default), or "quarter"maxAllocationPct: Cap per strategy (default: 25%)minTrades: Minimum trades for valid calculation (default: 10)sortBy: Sort by "kelly", "winRate", "payoffRatio", "allocation", "name"useMarginReturns: Use percentage returns based on margin (better for compounding strategies)
Tool returns:
- Win rate and payoff ratio (inputs to Kelly formula)
- Raw Kelly percentage (what the formula suggests)
- Adjusted allocations at full/half/quarter Kelly
- Per-strategy breakdown if multiple strategies exist
- Warnings (e.g., "Portfolio Kelly exceeds 25%", "negative Kelly")
Important context for Kelly:
- Full Kelly is mathematically optimal but assumes perfect knowledge of edge
- Half Kelly is commonly used to account for estimation uncertainty
- Negative Kelly indicates historical losses exceeded wins (Kelly formula doesn't apply)
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

risk is a skill published in the GitHub repository davidromeo/tradeblocks-skills (2 stars, last pushed 5mo ago), licensed MIT. It adds 43 tokens to every session and 2,088 once invoked, about $0.0002 per session on Opus 5. 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.
