etrade-oauth1-signature-flow skillA

etrade-oauth1-signature-flow is agent-read markdown (skill) from himanshuj16/algo-trading-skills: Use when integrating E*TRADE, which signs every request with OAuth 1.0a HMAC-SHA1 rather than OAuth 2.0 bearer tokens. Covers the three-legged flow with oauth_callback=oob, RFC 5849 signature base strings, and the idle and end-of-day expiry rules..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
