Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.03660 | $0.03660 |
| Opus 5 | $0.01830 | $0.01830 |
| Sonnet 5 | $0.00732 | $0.00732 |
| Haiku 4.5 | $0.00366 | $0.00366 |
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 5d 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.
(`curl -s https://pypi.org/pypi/zaxy-memory/json`) How it starts
The opening of the file, as written. The whole thing — 218 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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/*.jsonlis 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_checkoutis the front door.
Conventions (followed here; match them)
Code
mypy --strictoversrcandzaxy_benchmarks— untyped defs are CI failures. Every module starts withfrom __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; autouseisolate_settingsintests/conftest.pyforcesZAXY_ENV=test. - Drift guards are load-bearing: MCP tool contract snapshot
(
docs/examples/mcp-tool-contract.json+ frozen tool count intests/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.

zaxy CLAUDE.md is an instructions file published in the GitHub repository syndicalt/zaxy (17 stars, last pushed 25d ago), licensed MIT. It adds 3,660 tokens to every session, about $0.0183 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
