Agent365-devTools CLAUDE.md

A repository guide for Microsoft Agent 365 DevTools, a .NET command-line program for deploying and managing Agent 365 applications on Azure. It records the project structure, build steps, installation commands, and tests.

In plain words
What is it for?
Use it when changing the Agent 365 DevTools CLI, restoring dependencies, building its .NET projects, installing it locally, or running xUnit tests and coverage checks.
Why use it?
It gives a coding agent the project context and exact commands needed to build, install, and test the tool without rediscovering them.

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.

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

Agent365-devTools CLAUDE.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 2d 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.

Project Overview

Microsoft Agent 365 DevTools CLI (a365) - A .NET CLI tool built on .NET 8.0 with support for running on .NET 8.0 or higher (e.g., .NET 9, 10). Used for deploying and managing Microsoft Agent 365 applications on Azure. Supports .NET, Node.js, and Python applications with auto-detection.

Build Commands

# Install CLI locally (from repo root)
.\scripts\cli\install-cli.ps1

# Manual build and install
cd src/Microsoft.Agents.A365.DevTools.Cli
dotnet clean
dotnet build -c Release
dotnet pack -c Release --no-build
dotnet tool install -g Microsoft.Agents.A365.DevTools.Cli --add-source ./bin/Release --prerelease

# Restore all dependencies
cd src
dotnet restore dirs.proj
dotnet restore tests.proj

# Build all projects
dotnet build dirs.proj --configuration Release

Test Commands

# Run all tests
cd src
dotnet test tests.proj --configuration Release

# Run specific test class
dotnet test --filter "FullyQualifiedName~SetupCommandTests"

# Run with coverage
dotnet test --collect:"XPlat Code Coverage"

Test Framework: xUnit with FluentAssertions and NSubstitute

Test Location: src/Tests/Microsoft.Agents.A365.DevTools.Cli.Tests/

Parallel Test Execution: Tests modifying environment variables or shared resources must disable parallelization:

[CollectionDefinition("EnvTests", DisableParallelization = true)]
public class EnvTestCollection { }

[Collection("EnvTests")]
public class MyTests { }

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.
