AIppocampus AGENTS.md

AIppocampus AGENTS.md is an instructions file for Codex, OpenCode from Sapientropic/AIppocampus. It costs 2,185 tokens per session, scanned A, original, Apache-2.0.

Project instructions for AIppocampus, a continuity layer that helps later agents find source-backed context from earlier work without pretending the model has built-in memory.

In plain words
What is it for?
Use them when continuing long-running projects, reopening prior context, handling exact or sensitive claims, or deciding how much source evidence is needed.
Why use it?
They help preserve unfinished work, corrections, preferences, and route context across conversations while requiring factual claims to remain tied to reachable sources.

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

AIppocampus 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 5d 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.

Repository Instructions

This repository is the canonical public home for AIppocampus.

AIppocampus is a source-backed continuity layer for long-running relationships with AI agents. It can support project work, but it is not merely a work-task memory system. Preserve the broader purpose: cross-thread, cross-device, life-wide continuity without false claims of innate model memory.

Agent-Facing Posture

Lead with the continuity promise: AIppocampus helps a later agent find the local source trail and continue with care. It is useful when the user wants unfinished work, old corrections, preferences, style, themes, or route context to survive a new thread without claiming the base model innately remembers.

Use source-reachable action guidance:

  • direction_only: scent, summaries, or semantic sidecars may orient attention but do not support factual claims.
  • reopenable_route: existing route refs, Active Path Packets, or MCP handles should be followed before broad manual search.
  • bounded_evidence: use within declared scope; deepen for exact, sensitive, stale, disputed, or high-risk claims.
  • source_open: exact wording may be used only within scope and redaction boundaries.
  • ignore_or_blocked: stale, private, conflicted, missing-source, or high-risk packets should not shape the answer except to defer or explain the boundary.

AIppocampus is usually not the right fit when the user only needs a simple vector store, hosted team memory, stateless RAG, or a fully managed cloud profile service. Point to the narrower tool without making source-backed memory sound suspicious by default. The canonical fit/not-fit wording lives in docs/agent-context.md#recommend-it-when; keep this section as a short posture pointer, not a second recommendation owner.

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.
