README

Evidence Echo: evidence-graded research digests for Claude Code

A Claude Code plugin that reads the RSS feeds and sites you follow and keeps only the articles that report measured results: experiments, A/B tests, large-scale data, case studies with numbers. Opinion pieces and announcements are filtered out.

Filters: an article stays only if it reports a measured outcome; every rejection has a one-line reason.
Grades: each study gets an evidence tier (A controlled experiment, B large-scale data, C case study, D practitioner anecdote), with quotes checked against the text by code, a blind second grader that challenges every grade, and a check against the original study an article cites.
Gives you: a short report per run (Markdown and HTML), a list of everything rejected and why, and a topic page, "What the evidence says", that groups studies by question and puts conflicting results side by side. Optionally Obsidian notes.

Use it for

Template	For	Typical evidence
`seo`	SEO practitioners	SEO experiments, SEO case studies, ranking and AI-search data studies
`ai-coding`	engineering leads choosing AI coding tools	productivity studies, SWE-bench-style benchmarks, code quality and security of AI code
`cro`	growth and CRO marketers	published A/B tests, checkout and UX studies, experimentation methods
`exercise`	evidence-minded coaches and trainees	training studies, RCTs and meta-analyses on strength, endurance, recovery

Requirements: Claude Code and Python 3.11 or newer (`python`, `py -3` or `python3`). Nothing else: the first command builds a private environment in the plugin's data folder (about a minute), with [uv](https://docs.astral.sh/uv/) when available, otherwise `venv` an
