Memory

Your canonical memory lives in memory/AGENTS.md and renders to each agent’s native memory file — CLAUDE.md for Claude, AGENTS.md for OpenCode.

Compose from fragments

Keep the top-level file small and pull in reusable pieces with @import:

~/.agentsync/memory/AGENTS.md

# Coding conventions

@import ./fragments/style.md
@import ./fragments/security-rules.md

layout

~/.agentsync/memory/
├── AGENTS.md
└── fragments/
    ├── style.md
    └── security-rules.md

At apply time agentsync expands the imports and writes the fully-composed memory into each agent’s native file. Edit a fragment once and every agent’s memory updates on the next apply.

Fragments are reusable

A fragment like security-rules.md can be imported by several memory files (for example a user-level memory and a project overlay). Define the rule once, use it everywhere.

Per-agent rendering

Agent	Native memory file
Claude Code	~/.claude/CLAUDE.md
OpenCode	~/.config/opencode/AGENTS.md
Codex (planned)	~/.codex/AGENTS.md
Cursor (planned)	AGENTS.md (project root)

Memory is ✓ native on Claude and OpenCode — the same markdown, full fidelity — and on Codex’s planned projection (~/.codex/AGENTS.md). Cursor keeps user-level rules in app-local storage, so memory projects to a project-root AGENTS.md only (◐). See the capability matrix for detail.

Project-local memory A repo's .agentsync.toml overlay can merge extra memory on top of your user-level memory.
