Memorythreads — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Memorythreads (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Persistent, searchable conversation memory shared across Claude Code and Codex.
MemoryThreads is a local MCP server that auto-captures every conversation turn from both Claude Code and OpenAI Codex into one SQLite database, then makes that history instantly searchable from any future session - hybrid BM25 (FTS5) + vector (sqlite-vec) recall, with cross-platform thread continuity. Start work in Claude Code, continue it in Codex, and either side can recall the full shared history.
No cloud, no account - everything lives in ~/.claude/memory-server/ on your machine.
LLM coding sessions are stateless - close the terminal and the context is gone. MemoryThreads fixes that:
recall_context("that auth bug from last week") pulls the actual prior turns. Claude Code ─┐ ┌─ recall_context / search_docs
├─ hooks ─► jobs queue ─► worker.js ─► SQLite ◄─┤ (MCP tools)
Codex ─┘ (capture) (parse + embed) └─ mt launch (resume)incremental-sync.js) also ingests Claude Code turns continuously.worker.js parses transcripts (dual-format: Claude Code JSONL and Codex rollout JSONL via transcript-parser.js), stores turns + threads, and embeds each turn (OpenAI text-embedding-3-small, 1536-dim) into a sqlite-vec table.server.js) exposes recall_context, which runs hybrid BM25 + cosine search over turns/threads and returns the matches to the model.canonical_thread_id links a Claude Code stream and a Codex stream into one logical MemoryThread, so continuation works across both tools without sharing native session files.| Tool | Purpose |
|---|---|
recall_context(query, resolution=0, include_threads) | Hybrid BM25 + vector search. resolution 0 = raw turns (default), 1 = full threads, 2 = thread key-exchanges. |
search_docs(query) | FTS5 search over ingested reference docs. |
ingest_doc(source, tags?, title?) | Add a reference doc (URL, llms.txt, or local file). |
list_docs / delete_doc | Manage ingested docs. |
save_thread(name, ...) | Bookmark the current session as a named MemoryThread. |
list_threads / activate_thread / delete_thread | Manage and resume bookmarks. |
/mt-save <name>, /mt-list, /mt-delete <name>, /mt-doc-ingest <source>mt launch (terminal) - interactive picker to resume a saved thread.One SQLite DB (data/memory.db). Core tables: threads, turns, turns_fts (FTS5), turn_embeddings (sqlite-vec), plus saved_threads, active_memory_threads, docs, tool_uses, summaries, recovery_buffer, and the worker jobs queue. Full DDL in SCHEMA.md.
Recall operates directly over conversation turns and threads - there is no extracted-knowledge layer.
