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 | $0.01746 | $0.01746 |
| Opus 5 | $0.00873 | $0.00873 |
| Sonnet 5 | $0.00349 | $0.00349 |
| Haiku 4.5 | $0.00175 | $0.00175 |
Grade A, and why
eodhd-claude-skills CLAUDE.md 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 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.
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.

EODHD Claude Skills
Overview
Plugin enabling AI agents (Claude Code, Codex) to work with the EODHD financial data API. Distributed as a Claude Code plugin (EodHistoricalData/eodhd-claude-skills). Version: 0.5.2.
Includes MCP Server connector (OAuth), 13 skills (1 core + 7 workflow + 5 user-facing commands), financial analyst agent, 64 endpoint docs, 28 general guides, and a stdlib-only Python client. As of v0.5.2 the user commands (eodhd-analyze etc.) live under skills/ as standard skills and are invoked namespaced (e.g. /eodhd-api:eodhd-analyze) — the legacy commands/ directory was removed because its flat files did not load as usable commands in a live session on newer Claude Code (verified live on 2.1.158 and 2.1.161: all 13 skills load).

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.

eodhd-claude-skills CLAUDE.md is an instructions file published in the GitHub repository EodHistoricalData/eodhd-claude-skills (38 stars, last pushed 13d ago), licensed MIT. It adds 1,746 tokens to every session, about $0.0087 per session on Opus 5. A static security scan graded it A with 0 findings.
