Silex: Instructions file for Codex

AGENTS.md

Silex AGENTS.md is an instructions file for Codex, OpenCode from silexlabs/Silex. It costs 1,449 tokens per session, scanned A, original, AGPL-3.0.

A project guide for coding agents working on the Silex software project. It explains the project’s tools, how to run it locally, how to build its desktop app, and where to edit source code.

In plain words
What is it for?
Use it when editing Silex source, running the project on your computer, or building the desktop application.
Why use it?
It gives the agent the project-specific rules and commands needed to make changes without guessing how Silex is organised or run.

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

Silex 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 14d 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.

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.
