Sia: Instructions file for Codex

AGENTS.md

Sia AGENTS.md is an instructions file for Codex, OpenCode from GetPullRequest/Sia. It costs 262 tokens per session, scanned A, original, MIT.

Repository instructions for working with Sia, an Nx workspace. Nx is a tool for managing multiple related projects in one code repository.

In plain words
What is it for?
They are for understanding the workspace, inspecting projects, running builds and tests through Nx, checking Nx configuration, and following the rule about generated code.
Why use it?
They tell developers which Nx commands and repository tools to use and prevent edits to generated files that would be overwritten later.

Written for Codex and OpenCode: the file is AGENTS.md.

This is GetPullRequest/Sia's own configuration. It tells Codex and OpenCode how to work on Sia itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Sia configures →

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

Sia 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 2mo 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.

What it actually says

General Guidelines for working with Nx

  • When running tasks (for example build, lint, test, e2e, etc.), always prefer running the task through nx (i.e. nx run, nx run-many, nx affected) instead of using the underlying tooling directly
  • You have access to the Nx MCP server and its tools, use them to help the user
  • When answering questions about the repository, use the nx_workspace tool first to gain an understanding of the workspace architecture where applicable.
  • When working in individual projects, use the nx_project_details mcp tool to analyze and understand the specific project structure and dependencies
  • For questions around nx configuration, best practices or if you're unsure, use the nx_docs tool to get relevant, up-to-date docs. Always use this instead of assuming things about nx configuration
  • If the user needs help with an Nx configuration or project graph error, use the nx_workspace tool to get any errors

Workspace specific guidelines

  • Never update any code inside "generated" folder because those are auto generated classes and models. Any subsequent code generation run will wipe out those changes.
Changes

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.
