asya: Instructions file for Codex

AGENTS.md

asya AGENTS.md is an instructions file for Codex, OpenCode from deliveryhero/asya. It costs 4,405 tokens per session, scanned C, original, Apache-2.0.

Project-specific guidance for AI coding agents working on Asya, a system that runs AI workloads on Kubernetes through message-passing actors. It covers the project structure, testing, and how messages are routed between components.

In plain words
What is it for?
Understanding Asya’s components, finding the correct files to edit, following its testing strategy, and handling message envelopes and deployment-related code.
Why use it?
It gives an agent the context and rules needed to change the project safely, reducing confusion about its architecture and source files.

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 C, and why

asya AGENTS.md scanned grade C with 2 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 1mo 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.

AGENTS.md

AI developer guidance for the Asya project.

Project Overview

Asya is an Actor Mesh framework for running AI workloads on Kubernetes using choreography (decentralized) instead of centralized orchestration. Actors communicate by passing envelopes through message queues; routing is embedded in each envelope, not managed by a central coordinator. Implemented with Crossplane Compositions for declarative actor deployment with inline sidecar rendering.

Core components (all in src/):

  • asya-sidecar (Go): envelope router injected into actor pods; Queue → Sidecar → Runtime → Sidecar → Next Queue
  • asya-runtime (Python): lightweight socket server loaded via ConfigMap; executes user handler, returns result. Source of truth: src/asya-runtime/asya_runtime.py (single file, no deps). deploy/helm-charts/asya-crossplane/files/asya_runtime.py is a symlink — editing the source automatically reflects in the Crossplane chart's ConfigMap. No manual sync needed.
  • asya-gateway (Go): optional MCP/HTTP gateway; exposes async actor pipelines as synchronous HTTP
  • asya-crew (Python): system actors — x-sink (persist results), x-sump (DLQ handling), x-pause (checkpoint envelope to S3 and signal paused), x-resume (restore envelope from S3 and re-inject into the mesh)
  • asya-lab (Python): CLI tools (asya mcp ..., asya flow ...) for debugging and flow compilation
  • asya-testing (Python): shared test fixtures and utilities
  • asya-state-proxy (Go): optional sidecar that gives actors virtual persistent state via filesystem emulation; actors read/write /state/... paths, runtime intercepts Python file I/O and forwards to the proxy over Unix socket; proxy translates to actual storage backend (S3, GCS, Redis, NATS KV) with configurable LWW or CAS guarantees; actors remain stateless Deployments — no StatefulSets

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.

asya AGENTS.md is an instructions file published in the GitHub repository deliveryhero/asya (59 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 4,405 tokens to every session, about $0.0176 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
