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.

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 | $0.00035 | $0.02640 |
| Opus 5 | $0.00017 | $0.01320 |
| Sonnet 5 | $0.00007 | $0.00528 |
| Haiku 4.5 | $0.00003 | $0.00264 |
Grade A, and why
third-party-agents 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 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.
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.

Visual Studio Code 中的第三方智能体(Third-party Agent)是由外部提供商（如 Anthropic 和 OpenAI）开发的 AI 智能体(Agent)。第三方智能体(Third-party Agent)让你能够使用这些 AI 提供商的独特能力，同时仍可受益于 VS Code 统一的智能体(Agent)会话(Agent Session)管理以及用于编码、调试、测试等的丰富编辑器体验。此外，你还可以通过现有的 GitHub Copilot 订阅使用这些提供商的服务。
VS Code 使用提供商的 SDK 和智能体(Agent)框架来访问智能体(Agent)的独特能力。你可以在 VS Code 中使用本地和云端第三方智能体(Third-party Agent)。云端第三方智能体(Third-party Agent)的集成通过你的 GitHub Copilot 计划启用。
注意 云端第三方编程智能体(Agent)目前处于预览阶段。
为什么使用第三方智能体(Third-party Agent)？
在 VS Code 中使用第三方智能体(Third-party Agent)的优势：
- 使用独特能力：每个第三方智能体(Third-party Agent)都有自己的优势和专业功能。VS Code 使用提供商的 SDK 和智能体(Agent)框架访问这些能力，让你能够为编程任务选择最合适的智能体(Agent)。
- 统一体验：从同一个 VS Code 智能体(Agent)体验中管理所有智能体(Agent)会话(Agent Session)，包括第三方智能体(Third-party Agent)。
- 丰富的编辑器集成：将 VS Code 的编码功能（如丰富的调试和测试）与智能体(Agent)能力相结合。
- 计费：通过现有的 GitHub Copilot 订阅进行身份验证和计费管理，无需额外设置。
启用第三方云端智能体(Cloud Agent)
在 VS Code 中使用云端第三方智能体(Third-party Agent)之前，需要在 Copilot 账号设置中启用对云端第三方智能体(Third-party Agent)的支持。请按照 GitHub 文档中在仓库中启用或禁用第三方编程智能体(Agent)的步骤操作。
💡 国内用户提示 如果您希望使用国内 AI 模型，安装 飞码扣插件 即可在 GitHub Copilot Chat 中使用通义千问(Qwen3)、DeepSeek、GLM 等模型，按次计费。了解更多 → 打开飞码扣
无需安装提供商的 VS Code 扩展即可在 VS Code 中使用其云端智能体(Cloud Agent)。
Claude 智能体（预览版）
Claude 智能体(Agent)会话(Agent Session)直接在 VS Code 中提供由 Anthropic Claude Agent SDK 驱动的自主编程能力。Claude 智能体(Agent)会自主操作你的工作区，使用自己的工具集和能力来规划、执行和迭代编程任务。
可通过 github.copilot.chat.claudeAgent.enabled 设置（由组织级别管理，如需更改请联系管理员）启用或禁用 Claude 智能体(Agent)会话(Agent Session)的支持。
启动 Claude 智能体(Agent)会话(Agent Session)
启动新的 Claude 智能体(Agent)会话(Agent Session)：
-
打开聊天视图（⌃⌘I / Windows、Linux：Ctrl+Alt+I），选择新建聊天（
+）。 -
选择本地或云端智能体(Cloud Agent)会话(Agent Session)：
- 对于本地会话，从会话类型下拉菜单选择 Claude
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.
- 5d ago First seen · 141 lines · 35 tokens per session scan A 50e9657243bb
third-party-agents is an agent published in the GitHub repository feimacode/feima-copilot-llms-extension (5 stars, last pushed 5d ago), licensed MIT. It adds 35 tokens to every session and 2,640 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 2026-08-31.

This document describes how the unified three-layer Device Agent architecture is implemented across different platforms. While the core framework (State, Processor, Command layers) remains consistent, each platform implements specialized agents optimized for their native control mechanisms and hierarchies.…
