push-omc

push-omc is a skill for Claude Code, Codex from jmstar85/oh-my-githubcopilot. It costs 0 tokens per session (1,479 once invoked), scanned A, original, MIT.

A bridge for moving a work session from GitHub Copilot to Claude Code, another coding assistant. It uses saved checkpoints to compare the two sessions before transferring work.

In plain words
What is it for?
Exporting a local OMG session to OMC, comparing checkpoint timestamps, and identifying newer files or conflicts before the transfer.
Why use it?
It lets work continue in another coding tool while warning about missing checkpoints and possible file conflicts.

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

push-omc 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 4d 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.

/push-omc — Export OMG Session into OMC (omg → omc)

Trigger

  • Slash command: /push-omc
  • Keywords: "push omc", "omc 푸시", "omc로 보내기", "sync to omc", "export to omc"

Purpose

Push the local OMG (oh-my-githubcopilot) session into OMC (oh-my-claudecode) so work done in GitHub Copilot can continue in Claude Code. Counterpart of /resume-claude. Together they form the v1.4.3 bidirectional bridge (OMG ↔ OMC).

Workflow

Step 1 — Detect

Call omg_detect_external_session and find the entry where source === "omg" (the local session). If has_checkpoint is false, abort:

"OMG 체크포인트가 없습니다. omg_checkpoint를 먼저 호출해 현재 상태를 저장해주세요."

Step 2 — Compare

Call omg_compare_checkpoints. Look at external[].omg_newer_than_external to decide whether the push will progress real work or just collide.

Display:

현재 OMG 체크포인트: {timestamp}
OMC 상태:
  - 마지막 OMC 체크포인트: {external[omc].timestamp or "없음"}
  - OMG가 더 최신: {omg_newer_than_external ? "예" : "아니요"}

If OMC is newer (!omg_newer_than_external && external[omc].timestamp), warn the user — without force: true, files newer on the OMC side will go to conflicts[].

Step 3 — Confirm

Use vscode_askQuestions to confirm export and gate force carefully:

header: "push-omc"
question: "OMG 세션을 OMC로 푸시하시겠습니까?"
options:
  - label: "표준 푸시 (충돌 시 건너뜀)"
    description: ".omc/ 파일이 더 최신이면 보존하고 conflicts[]에 보고"
    recommended: true
  - label: "강제 푸시 (--force, .previous.{ISO}.json 백업 생성)"
    description: "OMC 측 변경을 덮어쓰고 회전 백업 3개를 유지"
  - label: "취소"
allowFreeformInput: false

Strong-default the standard option. Force mode should be a deliberate user choice — once .previous.{ISO}.json rotation hits N=3, older snapshots are pruned.

Step 4 — Export

Call omg_export_external_session({target: "omc", force: <chosen>}).

Pre-flight:

  • The exporter applies a project-identity guard. If the source checkpoint's workspace_root ≠ current workspace, it returns { success: false, reason: "workspace_mismatch" } BEFORE any file mutation. Surface the error and stop.

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.

push-omc is a skill published in the GitHub repository jmstar85/oh-my-githubcopilot (153 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,479 tokens. 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.
