A tool for generating and updating instruction files for different coding assistants from one shared project description. It can create files such as AGENTS.md, CLAUDE.md, .cursorrules, and editor-specific rule files.

Use it when setting up a new project or refreshing assistant instructions after changes to the project's structure, dependencies, documentation, or conventions.

Without synchronization, each coding tool may follow different or outdated project guidance. A shared source keeps those instructions aligned as the codebase changes.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00082	$0.01575
Opus 5.5	$0.00033	$0.00630
Sonnet 5.5	$0.00016	$0.00315
Haiku 4.5	$0.00008	$0.00158

Security

Grade A, and why

agents-sync 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 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.

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-sync

Generate and sync AI context files across every coding tool you use.

Prerequisites

Add to your Claude Code MCP config (.claude/settings.json or ~/.claude/claude_desktop_config.json):

{
  "mcpServers": {
    "agents-sync": {
      "command": "npx",
      "args": ["@googlarz/agents-sync"],
      "env": { "ANTHROPIC_API_KEY": "sk-ant-..." }
    }
  }
}

Then restart Claude Code to connect.

Commands

`/agents-sync init`

First-time setup. Reads your codebase and generates all context files.

When to use: New project, or starting from scratch.

What it does:

Scans your codebase (manifests, structure, source samples, docs, TODO/FIXME comments)
Extracts project metadata via Claude API
Generates canonical AGENTS.md
Derives CLAUDE.md, .cursorrules, .github/copilot-instructions.md, GEMINI.md, .windsurfrules, .clinerules, .roomodes, CONVENTIONS.md, .kiro/steering/agents-sync.md, .trae/rules/agents-sync.md
Saves a snapshot for drift detection

Usage:

Run /agents-sync init on this project

Claude will call agents_sync_init with the current project path.

`/agents-sync sync`

Re-sync after your codebase has changed. Preserves any manual customizations.

When to use: After major refactors, new dependencies, architecture changes.

Options:

Add --fast to skip Claude API call when drift is minor (re-derives from existing AGENTS.md, still refreshes MCP + codegraph sections for free)
Add --dry-run to preview changes without writing

Usage:

Sync my AI context files /agents-sync sync --fast

`/agents-sync derive`

Re-derive all tool files from the current AGENTS.md without re-running the scanner or calling the Claude API.

When to use: After manually editing AGENTS.md and wanting all tool files to reflect the changes immediately.

Usage:

/agents-sync derive I edited AGENTS.md, update all tool files

`/agents-sync drift`

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.

agents-sync is a skill published in the GitHub repository googlarz/agents-sync (5 stars, last pushed 5mo ago), licensed MIT. It adds 82 tokens to every session and 1,575 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
