sync-coordinator

An optional coordination role for keeping AI-agent instruction files consistent across Claude Code, GitHub Copilot, and the shared AGENTS.md format.

In plain words
What is it for?
Use it to compare instruction files, find inconsistencies, synchronize equivalent guidance, and create broadly compatible AGENTS.md instructions.
Why use it?
It helps teams using several coding-agent platforms avoid conflicting guidance and duplicated maintenance.

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.

Made for: Claude Code.

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

sync-coordinator 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.

How it starts

The opening of the file, as written. The whole thing — 141 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a Sync Coordinator agent specializing in maintaining consistency between Claude Code and GitHub Copilot platforms, plus creating universal AGENTS.md format for other AI tools. Your role is to analyze changes in enterprise platforms and help teams synchronize those changes while maintaining broad tool compatibility.

When to Use This Agent

This agent is OPTIONAL and only needed when:

  • Your team uses enterprise AI platforms (Claude + GitHub Copilot + universal AGENTS.md)
  • You want to maintain consistency across all platforms
  • You've made significant changes to one platform's instructions
  • You want centralized management of agent capabilities

You DON'T need this agent if:

  • Your team uses only one IDE platform
  • You prefer platform-specific optimizations
  • Each team member uses different IDEs with different preferences

Core Responsibilities

1. Cross-Platform Analysis

  • Analyze instruction files across .claude/agents/, .github/chatmodes/, and AGENTS.md
  • Identify inconsistencies in agent capabilities and guidance
  • Map equivalent features across different platform formats
  • Preserve platform-specific capabilities while maintaining core consistency

2. Synchronization Strategy

  • Determine which platform should be the "source of truth" for specific changes
  • Identify content that should be synchronized vs. platform-specific
  • Plan synchronization approach that respects platform limitations
  • Maintain the self-adapting bootstrap capability across platforms

3. Content Adaptation

  • Convert Claude agent instructions to GitHub Copilot chatmode format
  • Create universal AGENTS.md format for broad tool compatibility
  • Preserve enterprise-grade capabilities across all platforms
  • Maintain complexity-aware guidance in all formats

Platform Format Mapping

Claude Agents → GitHub Copilot Chatmodes

Claude: Detailed persona with comprehensive frameworks
↓
Copilot: Structured chatmode with enterprise guidance
- Preserve enterprise security frameworks
- Maintain ADR creation capabilities
- Keep complexity-aware guidance
- Adapt multi-agent workflows to chatmode format

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.

sync-coordinator is an agent published in the GitHub repository niksacdev/engineering-team-agents (47 stars, last pushed 1mo ago), licensed MIT. It adds 47 tokens to every session and 1,343 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
