claude-memex

A documentation management system for Claude Code that turns any project's docs into a persistent, compounding, LLM-maintained knowledge base — and enforces that discipline at tool-call time through hooks.

Status: alpha — v0.1.0 in development. Not yet published. Licence: MIT

Inspired by

This project is directly inspired by Andrej Karpathy's llm-wiki.md (April 2026), which describes a pattern for LLM-maintained personal wikis — raw sources on one side, a compounding wiki of LLM-authored markdown on the other, with the LLM doing all the bookkeeping.

Memex takes that idea and turns it into a Claude Code plugin:

• The wiki pattern becomes a seedable project template (/memex:init)
• The discipline that keeps the wiki healthy becomes a layer of Claude Code hooks that block tool calls which violate the contract
• The name nods to Vannevar Bush's Memex — the 1945 vision of a personal, curated, cross-referenced knowledge store that Karpathy's gist also cites

What it is

Memex ships as a hybrid:

1. A Claude Code plugin. Install it by adding this repo as a marketplace and installing the memex plugin — see Quick start below. Alternatively, install from the anthril-claude-plugins marketplace, which lists memex alongside other Anthril plugins. Either path gives you a set of slash commands, skills, subagents, and hook scripts.
2. A seedable template. Run /memex:init [profile] inside any project and Memex scaffolds a .memex/ tree, a matching memex.config.json, and the CLAUDE.md / AGENTS.md wiring to make the hooks active.

The plugin version-controls the behaviour (hook scripts, skills, profiles). Your project owns only its .memex/ tree and its config. When a hook logic bug is fixed upstream, every project using Memex gets the fix by updating the plugin.

Profiles

Memex ships with presets you pick at init time:

Profile	For	Shape
engineering-ops	Working SaaS / product codebases	planning/{prds,rfcs,decisions}/, entities/, platform/{features,systems,integrations}/, workers/, agents/, workflows/, runbooks/, processes/, environments/, .audits/, .incidents/, .research/
research-wiki	Multi-source research — closest to Karpathy's original gist	raw/{articles,papers,books,transcripts,videos,interviews,standards,datasets,notes,assets}/, wiki/{entities,concepts,summaries,analyses,syntheses}/
research-project	Research + planning projects that will migrate into development	raw/*, wiki/*, research/{hypotheses,literature-review,methodology,experiments,prompts,roadmap.md}, architecture/, systems/, evaluation/
book-companion	Reading a long book with the LLM	raw/chapters/, wiki/{characters,places,themes,plot-threads}/
personal-journal	Self-tracking, reflection	raw/entries/, wiki/{topics,goals,reflections}/
generic	Minimal starting point	topics/, index.md, log.md, .open-questions/

All profiles share: AGENTS.md, index.md, log.md, .open-questions/. The rest is profile-specific. You can fork any profile, edit memex.config.json, and register your own — or use /memex:init-profile to build a custom profile interactively.

How it works

Three things make the wiki stay current instead of rotting:

1. The schema is a file. memex.config.json declares the allowed folders, the required frontmatter fields, the code-to-doc mappings. Hooks read the config — they don't hard-code rules. This is what makes Memex portable.
2. Enforcement at tool-call time. PreToolUse hooks block Write / Edit calls that violate path, README, or frontmatter rules. Stderr tells Claude exactly what was wrong; exit 2 surfaces the message so Claude can self-correct.
3. Session lifecycle keeps it live. SessionStart injects the index + recent log into Claude's context. UserPromptSubmit surfaces the top-3 relevant wiki pages. Stop appends a log entry and flags pages whose referenced code was touched without an updated: bump.

Other niceties

• Unicode-friendly slugs out of the box — Japanese, Greek, Cyrillic, Arabic, Hebrew, Thai and more. Set naming.asciiOnly: true if you want strict ASCII.
• Opt-in update notifications — set hookEvents.sessionStart.updateCheck: true to get a notice when a newer plugin release is published.
• Optional qmd integration — set search.engine: "qmd" for BM25 + vector retrieval; grep fallback is automatic.

See docs/concepts.md for the full model.

Quick start

# Install the plugin (once) — two equivalent paths:

# Option A: from this repo as its own marketplace
/plugin marketplace add anthril/claude-memex
/plugin install memex@claude-memex

# Option B: from the Anthril official plugin marketplace
/plugin marketplace add anthril/official-claude-plugins
/plugin install memex@anthril-claude-plugins

# Scaffold a project
cd my-project
/memex:init engineering-ops

# Ingest a source (research-wiki profile)
/memex:ingest .memex/raw/articles/some-article.md

# Ask the wiki a question
/memex:query "what do we know about authentication flows?"

# Health-check
/memex:lint

See docs/README.md for the full command reference and cookbook.

Why not just use CLAUDE.md?

CLAUDE.md is project memory — one file, read at session start, covering build commands and architectural notes. Memex is complementary, not a replacement:

• CLAUDE.md stays short and stable
• .memex/ is the multi-page knowledge tree CLAUDE.md points at
• Anthropic's claude-md-management plugin rolls session learnings into CLAUDE.md; Memex captures the broader knowledge that doesn't fit in one file

Use both. They solve different problems.

Development

Python 3.10+. Stdlib-only at runtime; pytest / ruff / mypy for development.

git clone https://github.com/anthril/claude-memex.git
cd claude-memex
python -m pip install -e ".[dev]"

pytest                                    # 227 tests, ~5s
ruff check hooks/ tests/ scripts/         # lint
mypy hooks/                               # type-check

CI runs all three across Ubuntu / macOS / Windows on Python 3.10 and 3.12.

Contributing

Read CONTRIBUTING.md first. Profile contributions are especially welcome — the schema is deliberately general enough that new presets should be a pure-data addition.

For bug reports and feature requests, use the issue templates under .github/ISSUE_TEMPLATE/.

For security issues, see SECURITY.md — please don't file public issues for vulnerabilities.

Community norms are set out in CODE_OF_CONDUCT.md.

Prior art

• Andrej Karpathy, llm-wiki.md (2026) — the conceptual origin.
• Vannevar Bush, "As We May Think" (1945) — the Memex essay the name nods to.
• Anthropic's claude-md-management plugin — complementary doc-audit tooling for CLAUDE.md.
