Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add instructions/vanrayliu/openallin/agents-mdgit clone --depth 1 https://github.com/vanrayliu/openallinWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.01524 | $0.01524 |
| Opus 5 | $0.00762 | $0.00762 |
| Sonnet 5 | $0.00305 | $0.00305 |
| Haiku 4.5 | $0.00152 | $0.00152 |
Grade A, and why
openallin 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 183 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenAllIn — Unified AI Coding Harness
A layered, composable engineering framework combining the best of OpenSpec, Superpowers, GSD, OMC, ECC, and Trellis.
Architecture
OpenAllIn uses a layered, composable design where each layer is independently optional and freely combinable:
┌─────────────────────────────────────────────────┐
│ Layer 6: Workspace — Project Memory & │ ← Trellis
│ Parallel Pipeline │
├─────────────────────────────────────────────────┤
│ Layer 5: Orchestration — Multi-Agent Team │ ← OMC
│ Coordination │
├─────────────────────────────────────────────────┤
│ Layer 4: Execution — Phase-Based Workflow & │ ← GSD
│ Context Engineering │
├─────────────────────────────────────────────────┤
│ Layer 3: Enhancement — Security / Memory / │ ← ECC
│ Learning / Verification │
├─────────────────────────────────────────────────┤
│ Layer 2: Skills — Engineering Methodology │ ← Superpowers
│ Library │
├─────────────────────────────────────────────────┤
│ Layer 1: Spec — Spec-Driven Development │ ← OpenSpec
└─────────────────────────────────────────────────┘
Core Principles
- Spec First — Align on requirements before writing code
- Engineering Discipline — Make best practices the default behavior
- Context Hygiene — Small tasks, phase separation, structured information
- Team Orchestration — Multiple agents collaborate like a real team
- Capability Enhancement — Security, memory, learning, verification loops
- Project Memory — File-based persistence over LLM memory

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.

openallin AGENTS.md is an instructions file published in the GitHub repository vanrayliu/openallin (11 stars, last pushed 4mo ago), licensed MIT. It adds 1,524 tokens to every session, about $0.0076 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
