Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is cesarandreslopez/sidekick-agent-hub's own configuration. It tells Codex and OpenCode how to work on sidekick-agent-hub 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 sidekick-agent-hub 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

sidekick-agent-hub 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.

AGENTS.md

This file provides guidance to Codex and other coding agents when working with code in this repository. CLAUDE.md mirrors the same project guidance for Claude Code.

Project Overview

Sidekick Agent Hub is an AI coding assistant and project-intelligence toolkit with real-time agent monitoring. It ships as a VS Code extension and a terminal dashboard. Inference can run through Claude Max, Claude API, OpenCode, or Codex CLI; session monitoring reads Claude Code, OpenCode, or Codex session data.

The repo is a small monorepo:

  • sidekick-vscode/ — VS Code extension, extension-host services, and webview source
  • sidekick-shared/ — canonical provider, parser, persistence, quota, transcript, and schema library used by the extension and CLI; published as sidekick-shared
  • sidekick-cli/ — Ink-based terminal dashboard and one-shot command suite; published as sidekick-agent-hub with the sidekick binary
  • docs/, mkdocs.yml, assets/, images/ — documentation site content and assets
  • scripts/ — cross-package build, lint, and version helpers

Build & Development Commands

Extension commands run from sidekick-vscode/:

npm run compile      # Dev build with source maps (esbuild)
npm run build        # Production build, minified
npm run watch        # Watch mode for development
npm test             # Run all tests (Vitest)
npm run test:watch   # Watch mode for tests

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.
