# mx
A Swiss army knife for Claude Code and multi-agent toolkits.
A Rust CLI providing encoded git operations, a SurrealDB-backed knowledge graph, session archival, GitHub sync, and emotional state tensors. Designed for use with Claude Code, but works with any multi-agent workflow that needs persistent memory, encoded commits, or session management.

## Installation
```bash
cargo install mx
```
Or from source:
```bash
cargo install --path .
```
Requires Rust 2024 edition. The binary is named `mx`.
## Quick Start
### Encoded Git Commits
`mx commit` wraps `git commit` but encodes the message using [base-d](https://crates.io/crates/base-d). The commit title is hashed and the body is compressed, each encoded through a randomly selected dictionary. The result looks like hieroglyphs in `git log` but decodes cleanly with `mx log`.
```bash
# Stage all and commit with an encoded message
mx commit "fix session export crash on empty JSONL" -a
# Stage all, commit, and push
mx commit "add semantic search to memory" -a -p
# See what the encoding produces without committing
mx commit --encode-only --title "refactor store" --body "split surreal and sqlite backends"
```
### Decoded Git Log
`mx log` has full parity with `git log` -- every display flag, format preset, and filter option works with transparent decoding.
```bash
# Last 10 commits, decoded (default)
mx log
# Last 3 commits (-N shorthand, like git log -3)
mx log -3
# One-line format with ref decorations
mx log --oneline
# Full details with diffstat
mx log -n 5 --full --stat
# Format presets: short, medium, full, fuller
mx log --format=fuller -3
# Filter by author, date, path
mx log --author="charlie" --since="1 week ago"
mx log -- src/handlers/
# Full patch output
mx log -p -3
```
### Decoded Git Show
`mx show` is a drop-in replacement for `git show` that transparently decodes encoded commit messages. All `git show` flags work as expected.
```bash
# Show the latest commit, decoded
mx show
# Show a specific commit with diffstat
mx show abc1234 --stat
# Show just the commit message, no diff
mx show --no-patch
# View a file at a specific revision (passes through to git show)
mx show HEAD:src/main.rs
```
### Knowledge / Memory
The memory system is a knowledge graph backed by SurrealDB (or embedded SurrealKV). Entries have categories, tags, resonance levels, embeddings, and relationships.
```bash
# Search knowledge entries
mx memory search "session bootstrap"
# Semantic (vector) search
mx memory search "how to handle state" --semantic
# Add a knowledge entry
mx memory add \
--category pattern \
--title "SurrealDB connection retry pattern" \
--content "When the connection drops, use exponential backoff..." \
--tags "surrealdb,reliability" \
--source-agent smith
# Show a specific entry
mx memory show kn-abc123
# List entries filtered by category
mx memory list -c insight
# Statistics
mx memory stats
```
Default categories: `pattern`, `technique`, `insight`, `gotcha`, `reference`, `decision`, `bloom`, `session`. Categories are customizable per-deployment -- run `mx memory categories list` to see available categories.
### PR Merge
```bash
# Squash merge (default) with encoded commit message
mx pr merge 42
# Rebase merge
mx pr merge 42 --rebase
# Standard merge commit
mx pr merge 42 --merge-commit
```
### Session Archival (Codex)
Archives Claude session JSONL files to permanent storage with transcripts, extracted images, and manifests.
```bash
# Archive the current session
mx codex archive
# Archive with clean markdown transcript only (no raw JSONL)
mx codex archive --clean
# Archive all unarchived sessions
mx codex archive --all
# List archived sessions
mx codex list
# Read an archived session
mx codex read <archive-id> --clean
# Search across all archives
mx codex search "memory migration"
```
### GitHub Sync
Pull and push issues/discussions as local YAML files.
```bash
mx sync pull owner/repo
mx sync push owner/repo --dry-run
mx sync labels owner/repo
```
## Configuration
Everything mx writes lives under a single base directory: `$MX_HOME`, default
`~/.mx/`. Each subsystem owns a subdirectory (`kv/`, `state/`, `memory/`,
`codex/`, ...). Move the whole tree by setting `MX_HOME`, or override one
subsystem at a time with vars like `MX_SURREAL_ROOT`, `MX_CODEX_PATH`,
`MX_KV_SCHEMA`, `MX_KV_DATA`, `MX_ISOLATE_FASTEMBED`.
Two env vars were removed in the path-alignment refactor (#259):
- `MX_MEMORY_PATH` -- use `MX_SURREAL_ROOT` instead. Setting the old name now
emits a one-line stderr note and is otherwise ignored.
- `MX_STATE_SCHEMA` -- replaced by the `mx state ... --schema {id|path}` CLI
flag. The default schema ID is now `tensor` (was `crewu`).
For the full layout, the complete env-var reference (including SurrealDB
connection vars, GitHub App auth, and tuning), legacy-fallback behavior, and
worked examples, see the **[filesystem layout](https://coryzibell.github.io/mx/paths.html)**.
