copilot-bridge: Skill for Claude Code

.agents/skills/copilot-model-sync/SKILL.md

copilot-model-sync is a skill for Claude Code, Codex from hooyao/copilot-bridge. It costs 162 tokens per session (7,071 once invoked), scanned A, original, no licence file.

A workflow for comparing a coding bridge’s supported model list with the current model list published by GitHub Copilot.

In plain words
What is it for?
Use it when adding support for a new Copilot model or removing support for one that Copilot has retired.
Why use it?
It helps keep the bridge from supporting models that Copilot has removed or missing models that Copilot has added.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is hooyao/copilot-bridge's own configuration. It tells Claude Code and Codex how to work on copilot-bridge itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything copilot-bridge configures →

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

copilot-model-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 9d 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.

Changes

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.
