zaxy: Instructions file for Claude Code

CLAUDE.md

zaxy CLAUDE.md is an instructions file for Claude Code from syndicalt/zaxy. It costs 3,660 tokens per session, scanned A, original, MIT.

A set of project instructions for Zaxy, a tool that stores an agent team's history as linked records and lets agents retrieve cited memories.

In plain words
What is it for?
Use it when changing Zaxy's code, documentation, command-line tool, or storage system, especially when deciding which database or project files may be changed.
Why use it?
It tells coding agents which files and architecture rules are authoritative, helping them avoid corrupting stored history or relying on outdated guidance.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions AGENTS.md.

This is syndicalt/zaxy's own configuration. It tells Claude Code how to work on zaxy itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything zaxy configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

zaxy CLAUDE.md scanned grade A with 1 finding 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 2mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

CLAUDE.md — Zaxy operating manual

Zaxy is an event-sourced memory runtime for agent fleets: append-only hash-chained JSONL (Eventloom) → embedded LadybugDB graph projection → cited Memory Checkout. Published to PyPI as zaxy-memory (CLI binary zaxy). Docs site: zaxy.io.

Controlling docs: this file + docs/architecture.md + README.md. AGENTS.md is historical and stale (pre-3.1 CLI, retracted-era metrics) — do not trust it over current code or docs/benchmarks.md.

Architecture invariants (violating these is never a refactor)

  • .eventloom/*.jsonl is the source of truth. Never edit, truncate, or delete it. Everything else — embedded.kuzu, caches, graph — is a replayable projection: safe to move aside and rebuild, never precious.
  • Embedded LadybugDB is the default backend (file-based, in-process, zero-daemon). Neo4j is an optional sidecar; pggraph is experimental. Don't write code or docs that assume Neo4j is primary.
  • One owner per store: LadybugDB takes an exclusive write lock. Multiple owners = corruption (see incident history in docs/superpowers/specs/2026-06-16-embedded-single-owner-reaping-investigation.md).
  • MCP is the primary interface; the CLI is the human/debug surface. memory_checkout is the front door.

Conventions (followed here; match them)

Code

  • mypy --strict over src and zaxy_benchmarks — untyped defs are CI failures. Every module starts with from __future__ import annotations.
  • ruff: E,F,I,N,W,UP,B,C4,SIM, line length 100, Google docstrings, double quotes. Run as CI does: ruff check src tests zaxy_benchmarks && mypy src zaxy_benchmarks.
  • Comments are sparse; where present they are multi-line rationale at non-obvious seams, not narration. Docstrings: one behavioral line, sections only for real contracts.
  • Heavy imports in the CLI go through patchable lazy seams (see _graph_store, src/zaxy/cli/runtime.py:45) so startup stays cheap and tests can monkeypatch.

Tests

  • Karpathy rule: every function gets a test; tests ship in the same commit as src.
  • Every test has a one-line behavioral docstring stating the guarantee.
  • Idioms: tmp_path, monkeypatch, typer.testing.CliRunner; autouse isolate_settings in tests/conftest.py forces ZAXY_ENV=test.
  • Drift guards are load-bearing: MCP tool contract snapshot (docs/examples/mcp-tool-contract.json + frozen tool count in tests/test_mcp.py), version guard, coverage-ratchet test, docs drift guard pinning export versions.

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.
