## What it does

This skill runs a sequential 7-phase check for .NET projects. It covers the build, analyzer diagnostics, antipattern detection, tests, package vulnerabilities, formatting, and `git diff` review.

It uses `dotnet build` for compilation, `dotnet test` for tests, and `dotnet format --verify-no-changes` to check formatting. Diagnostic and antipattern phases call the Roslyn MCP tools `get_diagnostics` and `detect_antipatterns`. Each phase reports PASS, WARN, or FAIL.

A build or test failure stops the remaining phases because later results would not be meaningful. Roslyn checks require MCP access, so its connection is worth checking before a full run.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill verify -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/verify/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/verify/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill verify -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/verify/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill verify -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/verify/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install codewithmukesh/dotnet-claude-kit verify
```

2. **Manually: put the files in place**
- File: `.github/skills/verify/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill verify -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/codewithmukesh/dotnet-claude-kit --path skills/verify
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/verify/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add codewithmukesh/dotnet-claude-kit --skill verify -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/codewithmukesh/dotnet-claude-kit/tree/HEAD/skills/verify/SKILL.md

## When to use it
- check a .NET build before review
- find new analyzer warnings
- detect `async void` and sync-over-async calls
- scan packages for vulnerabilities
- review `git diff` for unintended changes

## Example prompts
- \`/verify`
- Run all checks before I create a PR.
- Which verification phases should run after a dependency update?

  Run a comprehensive 7-phase verification pipeline for .NET projects: build,
  analyzers, antipattern detection, tests, security, formatting, and diff
  review. Each phase produces PASS/FAIL with actionable output and the pipeline
  short-circuits on critical failures. Also the authority on verification
  strategy: which phases to run for a given change, quality gates, and
  fix-and-retry loops. Use when: "verify", "check everything", "is this ready",
  "pre-PR check", "run all checks", "quality gate", "verification strategy",
  "which checks should run", or after completing a feature or refactor.

# /verify -- 7-Phase Verification Pipeline

## What

Runs a sequential, 7-phase verification pipeline that catches issues at every level --
from compiler errors to subtle antipatterns to formatting drift. Each phase produces
an explicit PASS, WARN, or FAIL with details. "It looks fine" is not a verification
result; a table of statuses is. Critical failures (Phase 1 build, Phase 4 tests)
short-circuit the pipeline because later phases cannot produce meaningful results
on broken code.

The pipeline answers one question: **"Is this code ready for review?"**

| Phase | Tool | What It Catches | Critical |
|-------|------|-----------------|----------|
| 1. Build | `dotnet build` | Compilation errors, missing references | Yes |
| 2. Diagnostics | `get_diagnostics` (MCP) | New analyzer warnings, nullability issues | FAIL on new errors |
| 3. Antipatterns | `detect_antipatterns` (MCP) | async void, sync-over-async, `DateTime.Now`, more | No |
| 4. Tests | `dotnet test` | Failing tests, regressions | Yes |
| 5. Security | `dotnet list package --vulnerable` + scan | Secrets, SQL injection, missing auth, vulnerable packages | FAIL on critical/high |
| 6. Format | `dotnet format --verify-no-changes` | Style drift, formatting inconsistencies | No |
| 7. Diff Review | `git diff` analysis | Accidental changes, debug leftovers, TODOs | No |

## When

- After completing a feature, bug fix, or major refactor
- Before creating a pull request -- non-negotiable, full pipeline
- After merging upstream changes or updating dependencies
- When the user says "verify", "check everything", "is this ready", "run all checks"
- As the final step before marking a task complete

### Which Phases to Run

Full pipeline is the default. For scoped changes, run a subset:

| Scenario | Phases | Notes |
|----------|--------|-------|
| Feature complete / Pre-PR / new endpoint | All 7 | No shortcuts |
| Bug fix | 1, 2, 4 | Add a test first if none covers it |
| After refactor | 1, 2, 3, 4 | Correctness focus; add 5-7 if security-sensitive |
| Dependency update | 1, 4, 5 | Build, tests, vulnerability scan |
| Config or test-only change | 1, 4 | Build and test |
| Formatting only | 6 | Format check is sufficient |

When in doubt, run all 7. Extra phases cost minutes; a missed security issue costs
days of incident response. Never cherry-pick phases because a change "looks safe".

## How

### Phase 1: Build (CRITICAL -- short-circuits)

```bash
dotnet build --no-restore --verbosity quiet
```

- If the build fails, STOP. Report errors and fix before continuing -- nothing
  downstream is meaningful on code that does not compile.
