🔐 What's Inside

This project offers:

Secure-by-default guidance for all languages (e.g., input validation, secret handling, safe logging).
Language-specific secure patterns:
- ☕ Java
- 🟩 Node.js
- 🟦 C#
- 🐍 Python
"Do Not Suggest" lists to block risky Copilot completions (e.g., eval, inline SQL, insecure deserialization).
AI hallucination protections to prevent package spoofing, non-existent APIs, and misinformation risks.
Mentorship-style tips to help newer engineers build secure coding habits.
Custom agents & Agent Skills under agents/ and skills/ for repeatable AppSec workflows inside Copilot.
An installable GitHub Copilot CLI plugin under plugins/copilot-security for reusable AppSec agents and skills across projects.
An MCP server for seamless integration of these prompts into other projects.

🗂️ Prompt Catalogue

Explore the available prompts and their intended use cases:

These prompt files live under prompts/ in this repo and are intended to be copied into a consuming repository’s .github/prompts/.

Recommended workflow: start with the application-security-orchestrator agent (see agents/application-security-orchestrator.agent.md). It standardizes intake, then hands off to specialist agents (Analyst/Architect/Engineer) depending on whether you want findings, a threat model, or implemented fixes.

Prompt	Description	Intended Use
access-control-review.prompt.md	Review and report on access control / authorization architecture for project.	Perform analysis of the current architecture for access control and authorization within the project.
assess-logging.prompt.md	Identify unsafe logging and exposure of sensitive data.	Audit log output for leaks and recommend safer patterns.
business-logic-review.prompt.md	Analyze overall business logic flow and decision making.	Map application behavior and critique critical logic paths.
check-access-controls.prompt.md	Audit authorization and access control weaknesses.	Ensure RBAC/ABAC enforcement and consistent permission checks.
check-for-secrets.prompt.md	Detect hardcoded secrets and credentials.	Locate embedded keys or tokens and suggest secure storage.
check-for-unvalidated-genai-acceptances.prompt.md	Find unvalidated AI-generated code or hallucinated assets.	Verify that AI suggestions are real, tested, and documented.
add-content-security-policy.prompt.md	Design, implement, and roll out a new Content Security Policy (CSP) safely.	Add CSP to a web app with a deployable policy string, rollout plan, and verification steps.
csp-review.prompt.md

🧑‍💻 Agents

📦 How to Use in a Real Project

Tip for contributors: when adding a file under prompts/, update the Prompt Catalogue table.

Option 1: Leveraging Static Files

This option is best when you want to vendor a fixed set of guidance files directly into a repository instead of installing the reusable CLI plugin.

Copy the components you want from this repository into the matching .github/ locations in your target project:

From this repository	Copy into target project	Purpose
`copilot-instructions.md`	`.github/copilot-instructions.md`	Repository-wide default coding and security guidance
`prompts/*.prompt.md`	`.github/prompts/`	Reusable prompt files that can be run directly in Copilot
`agents/*.agent.md`	`.github/agents/`	Reusable specialist agents such as analyst, architect, or engineer
`skills/**/SKILL.md` and skill-local files	`.github/skills/`	On-demand skills, including any helper scripts kept inside each skill directory
`instructions/*.instructions.md`	`.github/instructions/`	Path-specific instructions for matching file globs

Notes:

If you copy a skill directory, copy the entire folder, not just SKILL.md. Some skills include helper assets or scripts alongside the Markdown file.
The root-level instructions/ folder in this repository is currently empty, so there are no path-specific instruction files to copy right now.
If you only need a subset, copy only the prompts, agents, or skills you plan to use.

Copy copilot-instructions.md into your repo under .github/copilot-instructions.md.
Copy whichever reusable folders and files you want to adopt:
- prompts into .github/prompts/
- agents into .github/agents/
- skills into .github/skills/
- instructions into .github/instructions/ when this repository provides them
Open the prompt or agent-enabled workflow you want to run within your IDE.
For prompt files, click the Run Prompt button at the top-right of the file.

ℹ️ Note: If you don't see the run prompt button; check to make sure the Chat: Prompt Files functionality is enabled in your settings
For agents and skills, invoke them from Copilot Chat after the files are present in .github/agents/ and .github/skills/.

Option 2: Leveraging the MCP Server

The MCP server simplifies the integration of secure coding prompts into your workflow. Follow these steps:

Run MCP from source

Install dependencies
```
npm install
```

Setup environment

cp .env.example .env

The MCP server reads configuration from a .env file. Customize the following variables as needed:

Variable	Description	Default
`server.port`	Port the MCP server listens on.	`8080`
`server.ssl`	Whether to use ssl for express server	`false`
`server.ssl.pfx`	Path to pfx file	`localhost.pfx`
`server.ssl.pfx.passphrase`	Passphrase for pfx file	`PFX_PASSPHRASE`
`server.hostname`	Hostname the server binds to.	`localhost`
`logger.transports.console.enabled`	Enable console logging output.	`false`
`logger.transports.console.level`	Log level for console output.	`info`
`logger.transports.amqp.enabled`	Enable AMQP-based logging.	`false`
`logger.transports.amqp.level`	Log level for AMQP transport.	`http`
`logger.transports.amqp.hostname`	Hostname of the AMQP broker.	`localhost`
`logger.transports.amqp.port`	Port for the AMQP broker.	`5672`
`logger.transports.amqp.username`	Username for AMQP authentication.	`guest`
`logger.transports.amqp.password`	Password for AMQP authentication.	`guest`
`logger.transports.amqp.exchange`

Run MCP in Docker

Build docker container
```
docker build -t copilot-security-mcp .
```

Run docker container

docker run -d -p 8080:8080 copilot-security-mcp

Configuring VSCode for MCP

Open VSCode and run the MCP: Open User Configuration command.

Add the following JSON configuration:

{
   "servers": {
      "copilot-instructions-mcp": {
         "url": "http://localhost:8080/mcp"
      }
   }
}

Save the configuration.
Navigate to the Extensions menu in VSCode.
Locate the copilot-instructions-mcp server, click the settings cog, and select start server.

Using MCP with GitHub Copilot

Open GitHub Copilot Chat.
Ask it to run any of the prompts against your repository or specific files.

Example: Please get and run the secure code review prompt.

Option 3: Using the `copilot-security` GitHub Copilot CLI Plugin

This repository ships an installable GitHub Copilot CLI plugin named copilot-security.

Plugins are reusable bundles of Copilot components such as agents, skills, hooks, and integrations. In this project, the plugin is published from the official marketplace repository:

robotti-io/copilot-security-instructions

The plugin manifest lives under plugins/copilot-security/.github/plugin/plugin.json, and the marketplace manifest for this repository lives under .github/plugin/marketplace.json.

What the plugin contains

The copilot-security plugin currently packages these reusable components:

Agents:
- application-security-analyst
- application-security-architect
Skills:
- access-control-review
- dependency-cve-triage
- threat-model

After installation, these agents and skills are available in any project where you use GitHub Copilot CLI.

Install from the official marketplace

GitHub documents CLI plugins here:

https://docs.github.com/en/copilot/concepts/agents/copilot-cli/about-cli-plugins
https://docs.github.com/en/copilot/how-tos/copilot-cli/customize-copilot/plugins-finding-installing

To register this repository as a plugin marketplace and install the copilot-security plugin:

copilot plugin marketplace add robotti-io/copilot-security-instructions
copilot plugin marketplace list
copilot plugin marketplace browse copilot-security-instructions
copilot plugin install copilot-security@copilot-security-instructions

Notes:

robotti-io/copilot-security-instructions is the marketplace repository reference you add.
copilot-security-instructions is the marketplace name exposed by this repository's marketplace.json.
copilot-security is the plugin name exposed by plugins/copilot-security/.github/plugin/plugin.json.

Install directly from the repository

If you do not want to register the marketplace first, you can install the plugin directly from this repository by pointing Copilot CLI at the plugin subdirectory:

copilot plugin install robotti-io/copilot-security-instructions:plugins/copilot-security

This form is required because the plugin manifest is stored in a plugin subdirectory, not at the repository root.

Install from a local checkout

For local development or testing from a cloned copy of this repository:

copilot plugin install ./plugins/copilot-security

Manage the installed plugin

Use the standard Copilot CLI plugin commands:

copilot plugin list
copilot plugin update copilot-security
copilot plugin uninstall copilot-security
copilot plugin marketplace remove copilot-security-instructions

You can also get command help with:

copilot plugin --help
