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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00042 | $0.00917 |
| Opus 5 | $0.00021 | $0.00458 |
| Sonnet 5 | $0.00008 | $0.00183 |
| Haiku 4.5 | $0.00004 | $0.00092 |
Grade A, and why
options-analyzer scanned grade A with 1 finding 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.

> `eodhd_client.py` helper** — call them with `curl` per the endpoint docs. Access depends on your plan/tier: How it starts
The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: options-analyzer
Purpose
Analyze US equity options using EODHD Marketplace data — options chains with Greeks, implied volatility analysis, contract comparison, and strategy evaluation.
Trigger
Activate when the user asks for:
- Options chain for a ticker
- Implied volatility analysis or IV rank
- Greeks analysis (delta, gamma, theta, vega)
- Options strategy evaluation (covered calls, spreads, straddles, etc.)
- Put/call ratio or options flow
- Unusual options activity
- Options expiration analysis
Workflow
- Identify the underlying — resolve to
TICKER.USformat (US options only) - Fetch options contracts list —
us-options-underlyingsfor available expirations - Fetch options chain —
us-options-eodfor specific expiration with Greeks - Fetch underlying price —
eodorreal-timefor current price context - Analyze — IV analysis, strategy payoff, Greeks exposure
- Compile options report
Note: Options endpoints (
us-options-eod,us-options-underlyings) are not wired into theeodhd_client.pyhelper — call them withcurlper the endpoint docs. Access depends on your plan/tier: on many paid plans the US options endpoints return data directly (HTTP 200), so don't assume a separate Marketplace add-on is required — verify against your account before telling the user it's gated. Option chains can be large (multi-MB); summarize, don't dump raw JSON into the chat.

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.

options-analyzer is a skill published in the GitHub repository EodHistoricalData/eodhd-claude-skills (37 stars, last pushed 13d ago), licensed MIT. It adds 42 tokens to every session and 917 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls).
