Organism Memory — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Organism Memory (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 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.

The primary manifest — the file an agent reads to learn what this artifact does.
A local memory layer for AI agents. Organism gives any LLM persistent, searchable memory across sessions — without sending your data to external APIs.
Organism uses a four-tier memory system. Tiers 0–2 run on every request. Tier 3 is offline and disabled by default.
Tier 0 Working memory Last-N messages from the database (no retrieval step)
Tier 1 RAG chunks Verbatim turns → rag_chunks — FTS5 full-text + HNSW vector
Tier 2 Facts LLM-extracted facts per session → facts + user_profile
Tier 3 Research Consolidation + LoRA sleep [experimental, off by default]Online pipeline (every request):

print(reply.reply)Organism wraps an existing OpenAI-compatible endpoint and injects memory into every request — no local GPU needed for inference.

Organism intercepts each request, retrieves relevant memory, injects it into the system prompt, and forwards to your backend. See docs/claude-code-proxy.md for the Claude Code / Anthropic variant.

Not designed for concurrent multi-process write access.Tier 3 includes ConsolidationWorker, LoRA sleep fine-tuning, and SSM neural memory. The infrastructure is present in organism/research/ but not active by default.
Enable consolidation:
consolidation:
enabled: true
summary_temperature: 0.0
summary_max_new_tokens: 1536When enabled, WriteService writes experience_blocks after each turn, and ConsolidationWorker processes them into memory_items which are retrieved alongside Tier 2 facts. LoRA training is architecturally wired but requires a separate training run to activate.
Single SQLite file, auto-initialized on first run.
