ctx-memory: Instructions file for Claude Code

AGENTS.md

ctx-memory AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from GhadiSaab/ctx-memory. It costs 2,237 tokens per session, scanned A, original, MIT.

Repository instructions for ctx-memory, a local memory system for coding agents. It stores project history in SQLite with vector search and writes project memory to AGENTS.md so agents can use it in later sessions.

In plain words
What is it for?
Use it when working on ctx-memory or changing its architecture, hooks, wrappers, memory pipeline, or agent integrations. It also records known issues and project-specific conventions.
Why use it?
It reduces the need to repeat past work, decisions, errors, and conventions when starting a new coding session. It also documents how memory is collected and injected for different agents.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: PostToolUse hook event, but also the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions subagents; mentions Claude Code.

This is GhadiSaab/ctx-memory's own configuration. It tells Claude Code, Codex and OpenCode how to work on ctx-memory 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 ctx-memory configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/ghadi/perso/Project12.

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

ctx-memory AGENTS.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 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.

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.

Project Memory (from previous sessions)

Project Memory

Architecture

  • Persistent memory layer for LLM coding agents (Claude Code, Codex, Gemini, OpenCode) backed by SQLite + sqlite-vec, exposed via MCP
  • Three-layer pipeline: Layer 1 (pure message/event processing) → Layer 2 (digest ≤500 tokens) → Layer 3 (project memory markdown merge)
  • Shell wrapper intercepts tool binaries, spawns MCP sidecar (Claude/OpenCode only), runs pipeline on session end
  • Claude: hooks fire live (PostToolUse) + JSONL reader seeds messages post-session
  • Codex: post-hoc only — reads ~/.codex/state_5.sqlite + rollout JSONL after session ends
  • OpenCode: MCP sidecar + AGENTS.md injection at startup
  • AGENTS.md used for context injection for Codex and OpenCode (written before spawning tool)
  • Non-interactive subcommands (update, mcp, login, etc.) bypass wrapper entirely via execFileSync
  • You want OpenClaw (from Discord) to be able to act directly on your local files instead of only replying with paste-ready output. I’m checking your local OpenClaw/GSD setup to see exactly which permission boundary is blocking that and what to change safely.
  • I successfully applied the config-side changes, but openclaw approvals set failed because its CLI syntax is different than expected. I’m switching to directly updating ~/.openclaw/exec-approvals.json, then I’ll verify and restart gateway.
  • Now I have the full picture. Here are all the problems:

  • Problems Found

  • 1. Project12 sessions go to wrong project ("ghadi")

  • Root cause: /home/ghadi is a git repo (has .git/). When you run claude from /home/ghadi/perso/Project12, git rev-parse --show-toplevel walks up and returns /home/ghadi — so the wrapper resolves it to the ghadi project instead of creating a Project12 project.
  • Fix needed in src/wrapper/project.ts: If gitRoot is a parent of cwd (not the same or a direct project root), fall back to using cwd itself.

  • 2. Architecture/decisions never saved in digests

  • Root cause: decisions in Layer 1 only come from:
    • "confirmation" pattern matches with extractedDecision
    • Messages typed as "decision"
  • When Claude announces architecture, it's just an assistant message — Layer 1 never classifies it as a "decision". So decisions: [] always, nothing reaches Layer 3's architecture section.
  • Fix needed: Layer 1 needs to extract decisions from assistant messages that match architecture/decision patterns (e.g. "I'll use...", "The architecture is...", "decided to...").

  • 3. llm-memory projects list didn't show Project12

  • Root cause: Same as #1 — Project12 was never registered. Its sessions went to the ghadi project.

  • 4. No messages captured (0 messages_raw despite JSONL existing)

  • Root cause: The JSONL reader runs at session end and finds the file by mtime >= sessionStartMs. But the current session's JSONL file is still open/being written, so the mtime check may race. Also, 0 messages in DB means seedBuffers with messages never ran (no messages seeded from JSONL).
  • Want me to fix these now? The priority order I'd suggest:
    1. Fix #1 (git root leaking to parent) — affects project isolation completely
    1. Fix #2 (decisions extraction) — affects architecture/memory quality
    1. Fix #4 (messages not seeded) — investigate why JSONL reader returns nothing for recent sessions
  • Now fix tryConfirmation in patterns.ts to extract a meaningful decision sentence instead of dumping the whole assistan…
  • "I'm using" still matches "using " in ARCH_SIGNALS. And "React 19 instead of 18" matches "react". Both are still appeari…
  • Clean! But "I'm using Subagent-Driven Development to build KubeQuest task by task" is in Architecture because it matches…
  • The real fix is to change the entrypoint guard to use import.meta.url instead of VITEST, but actually looking at th…
  • The fix: check if argv[1] ends with wrapper/index.js (the only valid case to run main()), rather than checking fo…

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.
