What is EverOS CLAUDE.md?

A set of instructions for working on EverOS, a Python framework that extracts, stores, and searches useful information from work in Markdown and supporting databases. It describes the project structure, commands, and engineering rules.

Use it when editing EverOS code, running its lint and test commands, or deciding where a new feature belongs.

It gives an agent the project context needed to make changes that fit the existing architecture and development practices.

How EverMind-AI/EverOS configures Claude Code

About the project

EverOS is a Python library and local-first memory runtime that gives AI agents a portable memory layer across apps, devices, and workflows. It stores conversations, files, and agent activity as readable Markdown while maintaining local indexes for retrieval and reuse. The catalogue add-ons provide commands, skills, hooks, and settings for using EverOS with coding agents.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01132	$0.01132
Opus 5.5	$0.00453	$0.00453
Sonnet 5.5	$0.00226	$0.00226
Haiku 4.5	$0.00113	$0.00113

Security

Grade A, and why

EverOS CLAUDE.md scanned grade A with 0 findings 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 6d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

EverOS — md-first Memory Extraction Framework

This is a Python framework for md-first memory extraction (lightweight; single-user or small-team).

Quick commands

uv sync                    # install deps
make lint                  # ruff (check + format-check) + import-linter
make format                # auto-fix formatting
make test                  # pytest tests/unit
make integration           # pytest tests/integration
make ci                    # full CI: lint + test + integration

Architecture

DDD layers with domain-owned ports, plus cross-cutting:

entrypoints  →  service  →  memory  ←  infra
cross-cutting, usable by every layer: core / component / config

entrypoints/ — cli + api (incl. HTTP middleware) + tui (protocol translation only)
service/ — bootstrap.py (the one assembler) + MemoryService / KnowledgeService / OpsService facades
memory/ — domain (models + ports + extract + search + strategies + reflection + custom_instructions)
infra/ — adapters implementing memory.ports (markdown + sqlite + lancedb + milvus) + the cascade and OME engines
component/ — injectable providers (llm / embedding / rerank / parser / tokenizer)
core/ — runtime base (errors / observability / context / utils.datetime)
config/ — configuration data (Settings + default.toml + custom_instructions)

Dependency rule: entrypoints → service → memory ← infra; entry points import only service (plus core / config). Enforced by import-linter.

Detailed: docs/architecture.md.

Engineering practices

Coding rules auto-loaded from .claude/rules/ (10 rules; the three always-loaded ones cover architecture / code-style / language-policy, the rest are path-scoped and load when Claude Code opens a matching file)
Workflows as slash commands in .claude/skills/ — /commit, /new-branch, /pr, /release
Project-level decisions in docs/ (low-frequency, human-judgment-required)
Language policy: the project targets a global audience — docs and code are English; CJK appears only in test fixtures and locale-suffixed mirrors. Scanned by make check-cjk.
Datetime discipline: never call datetime.now() / time.time() directly — use everos.core.utils.datetime. Enforced by make check-datetime.

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.
