sivtr: Instructions file for Codex

AGENTS.md

sivtr AGENTS.md is an instructions file for Codex, OpenCode from Ariestar/sivtr. It costs 3,701 tokens per session, scanned A, original, Apache-2.0.

General instructions for AI coding agents working on sivtr, a project whose purpose and technical details are only partly filled in here. They set communication and change-management rules, including using Simplified Chinese for user-facing explanations.

In plain words
What is it for?
Use them as general guidance when editing the repository, communicating with its users, or deciding whether a dependency change is appropriate. The excerpt does not provide enough detail to describe specific commands or features.
Why use it?
They reduce unnecessary changes and keep work consistent with the project's existing structure. They also require approval before adding, changing, or removing dependencies.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md.

This is Ariestar/sivtr's own configuration. It tells Codex and OpenCode how to work on sivtr 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 sivtr 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

sivtr AGENTS.md scanned grade A with 1 finding 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- Never hit `api.github.com` with raw `curl` or `Invoke-RestMethod`: unauthenticated calls share a low anonymous rate limit and fail with HTTP 403. Route through `gh api` instead.

AI Agent Instructions

This file is the single source of truth for AI coding assistants working on this project. Tool-specific instruction files, such as CLAUDE.md, should point here instead of duplicating these rules.

Keep this file limited to durable, cross-session guidance. Current progress, temporary state, and session scratch do not belong here.

Communication

  • Use Simplified Chinese for user-facing explanations, questions, progress updates, and summaries.
  • Keep code, identifiers, comments, logs, test names, and commit messages in English.
  • Match the surrounding language when editing existing documentation.

Working Agreement

  • Stay within the stated scope. Do not add, refactor, or improve unrelated functionality.
  • Preserve unrelated working-tree changes and never discard user work.
  • Follow the project's existing structure, conventions, and patterns.
  • Adding, updating, or removing dependencies is allowed and encouraged when it benefits the project. Always propose the change first and wait for the user's explicit approval before applying it.
  • If a request is ambiguous, risky, or has materially different approaches, explain the trade-offs and ask before changing files.
  • If the safest path is clear and within scope, proceed and state any important assumption.
  • Treat a request containing dry-run as read-only. Explain what would be done without modifying files or configuration.

Engineering Principles

  • Make the smallest precise change that solves the problem; avoid unrelated refactoring.
  • Identify business invariants and express each invariant in one authoritative place.
  • Centralize shared validation, configuration, authorization, caching, and API contracts.
  • Do not use broad try/catch blocks to swallow errors.
  • Do not hide failures behind silent fallbacks.
  • Prefer readable business flow over fragmented helper methods.
  • Do not split a cohesive workflow into many one-use private methods.
  • Introduce abstractions only for real reuse, a clear reduction in complexity, or an excessively long method.
  • Use the Unix toolchain integrated into the terminal when it is the best fit for the task.

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.
