agentsync: Instructions file for Codex

AGENTS.md

agentsync AGENTS.md is an instructions file for Codex, OpenCode from spxrogers/agentsync. It costs 6,674 tokens per session, scanned A, original, MIT.

Repository instructions for agentsync, a Go command-line tool that keeps AI coding-agent settings in one central configuration and generates each agent's native files.

In plain words
What is it for?
Use them when changing agentsync's configuration model, adapters, drift detection, secret handling, documentation, or synchronization commands.
Why use it?
They explain how shared settings, secrets, and changes between configurations are managed, preventing edits from being overwritten or drifting out of sync.

Instructions file for CodexOpenCode

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

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

agentsync 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 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.

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.

How it starts

The opening of the file, as written. The whole thing — 405 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Managed by agentsync — do not edit AGENTS.md directly. To change it, edit .agentsync/memory/AGENTS.md (or the relevant .agentsync/memory/fragments/*.md fragment) and run agentsync apply. Direct edits here are reported as drift and overwritten on the next apply.

CLAUDE.md

Project memory for Claude Code / agent sessions working on agentsync.

What this is

agentsync is a single-machine Go CLI that centrally manages AI coding-agent configurations (32 agents: ten deep adapters — Claude Code, OpenCode, Codex, Cursor, Gemini CLI, Continue, Windsurf, Roo Code, Cline, Grok Build — plus a 22-agent generic "breadth tier" for memory + MCP + skills). The user keeps a canonical config in ~/.agentsync/ (small TOML + markdown, committable to a dotfiles repo); agentsync apply renders it into each agent's native config. It's bidirectional: native edits are detected as drift and merged back via reconcile/import. Secrets are ${secret:…}/${env:…} references resolved at apply time from an age-encrypted vault.

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.
