memgw AGENTS.md

memgw AGENTS.md is an instructions file for Codex, OpenCode from holetexvn/memgw. It costs 984 tokens per session, scanned A, original, MIT.

A shared long-term memory gateway for AI coding agents. It stores information locally with SQLite and Git so tools such as Claude Code, Codex CLI, and other clients can share it.

In plain words
What is it for?
It helps install and configure the memory service, connect supported coding clients, and collect events for later processing.
Why use it?
It avoids keeping separate memories for each coding tool and lets agents retain useful information across sessions.

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.

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

memgw AGENTS.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 4d 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.

memgw — instructions for AI agents

memgw is a shared long-term memory gateway for AI coding agents: one local store (SQLite + git) that Claude Code, Codex CLI, opencode, and any MCP client read from and write to. This file is for you, the agent, in two situations: installing memgw on your user's machine, or working on this codebase.

Installing memgw for your user

The wizard is non-interactive when stdin is not a TTY (or with --yes), so you can run it directly:

npx @holetex/memgw setup --yes

What it does: creates ~/.memgw, generates auth keys, starts the gateway on 127.0.0.1:8930 (API) and :8931 (MCP), installs Claude Code hooks + MCP and Codex MCP when those clients exist, and installs reboot supervision (launchd on macOS, systemd --user on Linux; on Windows it prints the Task Scheduler command — run it).

Rules for you:

  1. The LLM key is the user's decision. Non-interactive setup skips the key, which leaves memgw in capture-only mode — a safe default, nothing is lost: events queue and get distilled retroactively once a key arrives. Tell the user this explicitly; do not pressure them for a key. When they provide one:
    npx @holetex/memgw key "<key>"     # provider auto-detected from the prefix
    
    (OpenAI, Anthropic, Groq, OpenRouter are recognised; the command also restarts the gateway so the key is live.) Never echo the key back, never commit it, never send it anywhere else.
  2. Verify, don't assume. After setup:
    curl -sf http://127.0.0.1:8930/health     # {"ok":true,...}
    npx @holetex/memgw doctor                 # every line should be ok (llm warns until a key is set)
    
  3. Codex capture is a watcher process. Codex has no hooks. From a permanent install on macOS/Linux, setup installs the watcher supervised automatically (launchd com.memgw.watch-codex / systemd memgw-watch-codex); on Windows or from the npx cache it prints the command — relay it to the user. Verify capture is really flowing with memgw status ("agents seen" must list a codex source after a Codex session).
  4. Do not edit files under ~/.memgw/data/ by hand — that is the memory store. Use the CLI (memgw save, memgw forget) or the MCP tools.
  5. Per-client connection commands (opencode, claude.ai, Hermes, generic CLIs) are in docs/03-INTEGRATION.md; the setup wizard prints the ones it could not do automatically — relay those to the user instead of dropping them.

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.

memgw AGENTS.md is an instructions file published in the GitHub repository holetexvn/memgw (4 stars, last pushed 22d ago), licensed MIT. It adds 984 tokens to every session, about $0.0049 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 2026-08-31.
