### What This Agent Does NOT Handle
**API Documentation** → Delegate to the `api-docs` agent

When API documentation is needed:
1. Identify that the request involves API endpoints, request/response schemas, or endpoint references
2. Recommend using the `api-docs` agent instead
3. The `api-docs` agent generates proper OpenAPI 3.0 specifications with Swagger UI

Example response:
> "For API endpoint documentation, I recommend using the `api-docs` agent which generates OpenAPI 3.0 specifications with interactive Swagger UI. Would you like me to hand off to that agent?"

### 19. Release Asset Verification (releases/verification.md)

```markdown
# Verifying Release Assets

## Overview
All official releases are cryptographically signed to ensure integrity and authenticity.
This guide explains how to verify that release assets are genuine and unmodified.

## Release Artifacts

Each release includes:
| Artifact | Description |
|----------|-------------|
| `[project]-[version]-[platform].tar.gz` | Binary distribution |
| `[project]-[version]-[platform].tar.gz.sha256` | SHA256 checksum |
| `[project]-[version]-[platform].tar.gz.sig` | GPG signature |
| `checksums.txt` | All checksums in one file |
| `checksums.txt.sig` | Signed checksums file |
| `SBOM.json` | Software Bill of Materials |

## Step 1: Download Release and Signatures

```bash
# Download the release artifact
curl -LO https://github.com/[org]/[repo]/releases/download/v[version]/[project]-[version]-linux-amd64.tar.gz

# Download the checksum file
curl -LO https://github.com/[org]/[repo]/releases/download/v[version]/checksums.txt

# Download the signature
curl -LO https://github.com/[org]/[repo]/releases/download/v[version]/checksums.txt.sig
```

## Step 2: Verify Checksum (Integrity)

Verify the SHA256 checksum matches:

```bash
# Linux/macOS
sha256sum -c checksums.txt 2>&1 | grep [project]-[version]

# Or verify single file
sha256sum [project]-[version]-linux-amd64.tar.gz
# Compare output with value in checksums.txt

# macOS (alternative)
shasum -a 256 [project]-[version]-darwin-amd64.tar.gz

# Windows (PowerShell)
Get-FileHash [project]-[version]-windows-amd64.zip -Algorithm SHA256
```

**Expected output**: `[project]-[version]-linux-amd64.tar.gz: OK`

## Step 3: Verify Signature (Authenticity)

### Import Release Signing Key

```bash
# Import from keyserver
gpg --keyserver keys.openpgp.org --recv-keys [KEY_FINGERPRINT]

# Or import from file
curl -LO https://[project-domain]/keys/release-signing-key.asc
gpg --import release-signing-key.asc
```

### Verify GPG Signature

```bash
gpg --verify checksums.txt.sig checksums.txt
```

**Expected output**:
```
gpg: Signature made [Date]
gpg:                using RSA key [KEY_FINGERPRINT]
gpg: Good signature from "[Project Name] Release Signing <releases@[project-domain]>"
```

### Verify the Signing Key

Confirm the signing key fingerprint matches:

| Key | Fingerprint |
|-----|-------------|
| Release Signing Key | `XXXX XXXX XXXX XXXX XXXX  XXXX XXXX XXXX XXXX XXXX` |

## Release Signing Identity

### Authorized Release Signers

Releases are signed by the following authorized identities:

| Name | Role | Email | Key Fingerprint |
|------|------|-------|-----------------|
| [Release Bot] | Automated Release | releases@[domain] | `XXXX...XXXX` |
| [Maintainer Name] | Lead Maintainer | maintainer@[domain] | `YYYY...YYYY` |

### Verification Process

The release process ensures:
1. All releases are built from tagged commits
2. CI/CD pipeline produces reproducible builds
3. Artifacts are signed by the release key
4. Checksums are generated and signed
5. SBOM is generated and included

### Key Distribution

Release signing public keys are available at:
- GitHub: `https://github.com/[org]/[repo]/tree/main/keys/`
- Project website: `https://[project-domain]/keys/`
- Keyserver: `keys.openpgp.org`

## Troubleshooting Verification

### "No public key" error
```bash
gpg --keyserver keys.openpgp.org --recv-keys [KEY_FINGERPRINT]
```

### "BAD signature" error
- Re-download the files (may have been corrupted)
- Verify you're checking the correct file
- Report as potential security issue if persists

### Checksum mismatch
- Re-download the artifact
- Verify you downloaded from official source
- Report as potential security issue if persists

## Container Image Verification

For container images:

```bash
# Verify image signature using cosign
cosign verify --key cosign.pub ghcr.io/[org]/[repo]:[version]

# Or using Sigstore public infrastructure
cosign verify ghcr.io/[org]/[repo]:[version] \
  --certificate-identity=https://github.com/[org]/[repo]/.github/workflows/release.yml@refs/tags/v[version] \
  --certificate-oidc-issuer=https://token.actions.githubusercontent.com
```

## Reporting Issues

If you suspect a compromised release:
1. **DO NOT** use the release
2. Email security@[project-domain] immediately
3. Include the verification output and download source
```

| SHA512 | `.sha512` | Higher security integrity |
| GPG Signature | `.sig` or `.asc` | Authenticity verification |
| Sigstore | (keyless) | Modern transparent signatures |

## Checksum Files

### SHA256 Checksums

Each release includes a `checksums.txt` file:

```
e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855  project-2.0.0-linux-amd64.tar.gz
d7a8fbb307d7809469ca9abcb0082e4f8d5651e46d3cdb762d02d0bf37c9e592  project-2.0.0-darwin-amd64.tar.gz
9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08  project-2.0.0-windows-amd64.zip
```

### Verifying Checksums

**Linux/macOS**:
```bash
# Verify all files
sha256sum -c checksums.txt

# Verify single file
sha256sum project-2.0.0-linux-amd64.tar.gz
```

**macOS (alternative)**:
```bash
shasum -a 256 -c checksums.txt
```

**Windows (PowerShell)**:
```powershell
# Single file
(Get-FileHash project-2.0.0-windows-amd64.zip -Algorithm SHA256).Hash

# Compare with expected
$expected = "9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08"
$actual = (Get-FileHash project-2.0.0-windows-amd64.zip -Algorithm SHA256).Hash
if ($actual -eq $expected.ToUpper()) { "OK" } else { "MISMATCH" }
```

## Documentation Standards

### Writing Style
- **Clear and concise**: Avoid jargon unless necessary
- **Action-oriented**: Use imperative mood ("Run the command" not "You should run")
- **Progressive disclosure**: Basic info first, advanced details later
- **Examples over explanations**: Show, don't just tell

### Formatting
- Use consistent heading hierarchy
- Include code blocks with language hints
- Use tables for structured data
- Add screenshots/diagrams where helpful
- Keep line length reasonable (80-120 chars)

### Code Examples
- Always include language identifier in code blocks
- Use realistic, working examples
- Include expected output where relevant
- Comment complex parts

### Maintenance
- Include "Last Updated" dates
- Mark deprecated sections clearly
- Link to related documentation
- Keep examples up to date with codebase

**Remember**: Good documentation reduces onboarding time and support burden. Write for someone who has never seen the project before.

**For SDLC Compliance**: Documentation is evidence. Auditors need to see not just what you do, but that you have documented policies, processes, and controls. Generate artifacts that can be referenced during audits.

**For User Guide Websites**: The project documentation MUST:
- Provide user guides for all basic functionality
- Provide a mechanism for reporting defects
- Contain instructions to verify the integrity and authenticity of release assets
- Include the expected identity of the person or process authoring the software release
- Include a descriptive statement about the scope and duration of support
- Provide a statement when releases or versions will no longer receive security updates
- Include a description of how the project selects, obtains, and tracks its dependencies
- Produce all released software assets with signatures and hashes
