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 | $0.01254 | $0.01254 |
| Opus 5 | $0.00627 | $0.00627 |
| Sonnet 5 | $0.00251 | $0.00251 |
| Haiku 4.5 | $0.00125 | $0.00125 |
Grade A, and why
Perigon.CLI copilot-instructions.md 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 yesterday.
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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GitHub Copilot Instructions
本仓库是 Perigon.CLI：一个 .NET 10 命令行开发辅助工具，同时提供 Blazor Server Studio Web UI、MCP Server、模块打包/安装、OpenAPI 客户端生成，以及基于 Roslyn/Razor 的代码生成能力。生成或修改代码时，请优先遵循本文件，并参考 .agents/agents/engineer.agent.md 与 .agents/skills 中的工程规范和技术栈技能。
General Guidelines
- 准确性和确定性最重要；没有足够依据时先查代码或说明，不要猜测。
- 没有明确要求时，不要私自构建整个项目；优先通过 IDE 诊断、静态检查和必要的局部测试判断正确性。
- 保持改动聚焦，不要顺手重构无关代码或改动用户已有变更。
- 用户可见文本需要考虑中英文本地化。Razor 中使用源生成器生成的
Localizer.<Key>常量，例如@Localizer.Get(Localizer.CodeGen)。 - 新增或修改本地化文本时，同时维护
src/Share/Localizer.zh-CN.resx与src/Share/Localizer.en-US.resx。
技术栈
- 主要语言：C#，目标框架
net10.0，启用 nullable 与 implicit usings。 - 包版本管理：
Directory.Packages.props中央包管理。 - CLI：
Spectre.Console.Cli、Spectre.Console、Microsoft.Extensions.Hosting、DI、OutputHelper。 - Studio Web UI：ASP.NET Core、Blazor Server interactive components、
Microsoft.FluentUI.AspNetCore.Components。 - MCP：
ModelContextProtocol.AspNetCore。 - 代码生成：Roslyn (
Microsoft.CodeAnalysis.*)、Microsoft.OpenApi、RazorEngineCore、模板与生成模型。 - 数据/映射/工具：Perigon.MiniDb、Mapster、Humanizer、共享 Helper/Context。
- 测试：xUnit v3、Moq、
Microsoft.NET.Test.Sdk。
项目结构与分层
src/Apps/CommandLine:perigondotnet tool 入口。命令只负责参数、上下文、输出和退出码，业务逻辑委托给 CoreMod。src/Apps/Dashboard: Studio Web 服务和 Blazor UI。使用 Fluent UI，业务逻辑通过 managers/services 调用。src/Modules/CoreMod: 主业务模块。Services负责编排流程，Managers负责 MiniDb 持久化和查询更新。src/CodeGenerator: Roslyn/OpenAPI/Razor 代码生成、模板和分析 Helper。src/Share: 共享实体、模型、常量、Helper、DefaultDbContext、SolutionContext、本地化资源和框架扩展。tests/StudioMod.Tests: 命令、服务、Manager、Helper、生成逻辑的行为测试。
依赖方向应保持为 App -> CoreMod -> CodeGenerator/Share；Share 不应依赖 App 层。
代码风格约定
- 使用文件范围 namespace，匹配周围代码的 primary constructor 风格。
- 优先使用已有 Helper、
ConstVal、SolutionContext、Localizer和 Mapster 映射模式。 - CLI 命令继承
AsyncCommand<TSettings>或AsyncCommand；Settings 继承CommandSettings并使用CommandArgument、CommandOption、Description。 - 新命令要在
src/Apps/CommandLine/Program.cs注册，并使用本地化描述、别名和示例。 - 用户输出使用
OutputHelper或AnsiConsole；Spectre 表格中的动态文本用Markup.Escape。 - Dashboard 使用 Fluent UI Blazor 组件和图标；不要把业务流程写进 Razor 组件。
- HTTP、文件、外部 API 和长耗时异步流程应传递
CancellationToken。 - 测试 HTTP 行为时使用 stub
HttpMessageHandler，不要访问真实网络。
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.

Perigon.CLI copilot-instructions.md is an instructions file published in the GitHub repository AterDev/Perigon.CLI (53 stars, last pushed 3d ago), licensed Apache-2.0. It adds 1,254 tokens to every session, about $0.0063 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.
