perseus-amd-act-ii: Instructions file for Codex

AGENTS.md

perseus-amd-act-ii AGENTS.md is an instructions file for Codex, OpenCode from tcconnally/perseus-amd-act-ii. It costs 769 tokens per session, scanned A, original, MIT.

Repository guidance for AI coding agents and people editing the Perseus project. It also explains the project’s stateful agent, which stores facts in an encrypted local memory system between sessions.

In plain words
What is it for?
Understanding the repository, following its contribution rules, and working on its memory-enabled agent.
Why use it?
It gives contributors the project map, editing rules, and architecture details needed to make changes safely.

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

perseus-amd-act-ii 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 9d 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.

AGENTS.md

Guidance for AI coding agents (and humans) working in this repository, plus a description of the agent this project actually ships.

The agent this repo ships

src/agent_memory_demo.py is a minimal but complete stateful agent:

  1. Inference is an open-weight model behind the Fireworks AI API (target deployment: AMD Instinct via ROCm/vLLM; no serving API attests which accelerator handles a request). Inference is stateless — the context window dies with the session.
  2. Memory is provided by Perseus Vault, an MCP-native, local-first, encrypted memory engine (single Rust binary). The agent remembers durable facts, then in a later session recalls them before prompting the model, so knowledge survives across sessions.
  3. Lifecycle: a decay tick ages rarely-used memories and archives noise (never deletes — the journal stays auditable), so recall quality holds as the store grows.

The key architectural claim: memory lives on the host CPU, not in GPU HBM. See docs/ARCHITECTURE.md.

Repo map

Path What it is
src/perseus_vault_store.py The memory interface. ReferenceStore (SQLite/FTS5, CPU, always runs) and BinaryStore (bridge to a real perseus-vault binary when PERSEUS_VAULT_BIN is set).
src/agent_memory_demo.py End-to-end agent: learn → new session → recall → infer → load → decay.
src/gemma_on_amd.py Bonus: same loop with Gemma 3 served locally by llama.cpp on an AMD CPU (partner challenge).
src/benchmark.py Measured throughput + footprint tables (1K/10K/100K) and published-spec economics.
src/economics.py The "one MI300X serves N agents" math. Every value tagged published-spec / projection / measured.
docs/ Architecture, benchmarks, and the pre-filled lablab submission.

Ground rules for agents editing this repo

  • The honesty rule is load-bearing. Never present a GPU/MI300X number as measured. Every benchmark row carries a data_source of measured, published-spec, or projection. If you add a number, tag it and cite it.
  • No secrets in code. Credentials come from .env (gitignored) via .env.example. Never inline an API key or token.
  • Keep the core stdlib-only. The demo and benchmark must run with no third-party install so any judge can reproduce them. Optional deps go in requirements.txt behind clear comments.
  • Everything must stay runnable offline. No network call may be required for the demo to complete; the Fireworks path is opt-in via FIREWORKS_API_KEY.
  • MIT-licensed and original. This is a hackathon submission requirement.

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.
