syncai copilot-instructions.md

syncai copilot-instructions.md is an instructions file for GitHub Copilot from dmtrkzntsv/syncai. It costs 1,229 tokens per session, scanned A, original, MIT.

Project instructions for SyncAI, a Go program that copies AI-assistant configuration files between tools such as Cursor, Copilot, Claude Code and Codex.

In plain words
What is it for?
Use them when changing or checking SyncAI, including building it, running a one-shot smoke test, understanding its command-line options and tracing file-copy behavior.
Why use it?
They explain how to build, run and verify the program, and how its different configuration file types are synchronized.

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.

Security

Grade A, and why

syncai copilot-instructions.md scanned grade A with 1 finding 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 5d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

`.github/workflows/syncai.yml` runs syncai against the repo's own `syncai.json` on every push (except `main` and `release/*`). It builds from source (`make build`) — do **not** reintroduce the cross-repo binary download;

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

This file provides guidance to a Coding Agent when working with code in this repository.

Build & run

  • make build — go mod tidy then build to bin/syncai.
  • make run — builds and then runs go run ./cmd -config syncai.json.
  • make clean — removes bin/.

There is no test suite in this repo (no *_test.go files). Verify changes with make build plus a manual smoke test against a temp working directory:

./bin/syncai -workdir /tmp/syncai-smoke -config /tmp/syncai-smoke/syncai.json -no-watch

CLI flags: -config, -workdir, -no-watch (one-shot for CI), -self-update, -version, -help.

Architecture

SyncAI is a polling watcher that propagates AI-assistant config files between agents (Cursor, Copilot, Claude Code, Codex). The whole program is a single Go binary; the moving parts split cleanly along four "sync kinds" defined in internal/model/model.go:

Kind Source config field Source unit Destination logic
context Agent.Context.Path single file verbatim copy
ignore Agent.Ignore.Path single file verbatim copy
rules Agent.Rules.Pattern files matched by glob content rewritten by per-agent rules generator (frontmatter shape differs between cursor's globs/alwaysApply and copilot's applyTo)
skills Agent.Skills.Pattern whole directory matched by glob every file inside the matched dir copied verbatim, preserving the in-skill relative path

Lifecycle

  1. cmd/main.go loads config, runs initialSync (dedup key kind|stem|rel, picks the newest mtime per logical file across agents), then enters a ticker loop at cfg.Interval() (default 5s).
  2. Each tick rebuilds the watched-file list via (config.Agent).Files() and diffs sha256 hashes against the in-memory filesState. Changes → (*SyncAI).Sync. Missing entries → (*SyncAI).Delete.
  3. Files() uses two distinct collectors: globPattern (file glob, used for rules) and walkSkillDirs (recursive walk of every matched directory, used for skills). Don't conflate them.

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.
