description	Publish the @magnet-ai/magnet-mcp-server package to NPM with version bumping and git tagging. Use when user says "publish to npm", "npm publish", "deploy to npm", "release to npm", "publish package", "bump version and publish", or "release new version".

NPM Deployment Skill

This skill guides users through correctly publishing the @magnet-ai/magnet-mcp-server package to NPM, including version management and git operations.

When to Use This Skill

Use this skill when the user requests:

• Publishing the package to NPM
• Releasing a new version
• Bumping the version and deploying
• Creating a new NPM release

Instructions

Step 1: Verify Git Status

Check that the working directory is clean and on the correct branch:

git status
git branch --show-current

Requirements:

• Working directory must be clean (no uncommitted changes)
• Should typically be on main branch for releases

If there are uncommitted changes, inform the user and ask them to commit or stash changes first.

Step 2: Sync with Remote

Ensure local branch is up to date:

git fetch origin
git status

If behind remote, pull the latest changes:

git pull origin main

Step 3: Install Dependencies

Ensure dependencies are current:

pnpm install

Step 4: Run Build and Validation

Build the TypeScript project and verify:

pnpm build

Run type checking:

pnpm tsc --noEmit

Verify the build output exists:

ls -la dist/index.js

If the build fails, stop and inform the user about the errors.

Step 5: Security Audit

Critical: Before publishing, verify no sensitive data will be leaked in the package.

5a: Preview Package Contents

Run npm pack in dry-run mode to see exactly what will be published:

npm pack --dry-run 2>&1

Review the file list carefully. The output shows all files that will be included in the tarball.

5b: Check for Sensitive Files

Verify these sensitive files are NOT in the pack output:

• .env (contains API keys)
• .mcp.json (contains API keys)
• .claude/settings.local.json (local settings)
• Any *secret*, *credential*, or *private* files

# This should return nothing or only show .env.sample
npm pack --dry-run 2>&1 | grep -E "\.env|\.mcp\.json|settings\.local|secret|credential|private" || echo "No sensitive files found"

If .env (without .sample) or .mcp.json appears, STOP and fix .gitignore before proceeding.

5c: Scan for Hardcoded Secrets

Check source files for hardcoded API keys or secrets (UUID pattern commonly used for API keys):

# Check for UUID-like strings in source files (potential API keys)
grep -rE "[a-f0-9]{8}-[a-f0-9]{4}-[a-f0-9]{4}-[a-f0-9]{4}-[a-f0-9]{12}" src/ dist/ --include="*.ts" --include="*.js" 2>/dev/null || echo "No hardcoded UUIDs found"

# Check for common secret patterns
grep -riE "(api[_-]?key|secret|password|token|credential)\s*[:=]\s*['\"][^'\"]{8,}['\"]" src/ --include="*.ts" 2>/dev/null || echo "No hardcoded secrets found"

If any hardcoded secrets are found, STOP and remove them before proceeding.

5d: Verify .gitignore Coverage

Confirm sensitive files are properly excluded:

# Check .gitignore has necessary entries
grep -E "^\.env|^\.mcp\.json|settings\.local" .gitignore

Expected entries:

• .env* (with !.env.sample exception)
• .mcp.json
• .claude/settings.local.json

5e: Report Security Audit Results

Display a summary to the user:

Security Audit Results:
✓ Package contents reviewed (X files)
✓ No sensitive files in package
✓ No hardcoded secrets in source
✓ .gitignore properly configured

Safe to proceed with publishing.

If any check fails, inform the user and do not proceed until issues are resolved.

Step 6: Check Current Version

Read the current version from package.json:

node -p "require('./package.json').version"

Display the current version to the user.

Step 7: Select Version Bump Type

Use AskUserQuestion to determine the version bump type:

Question: "What type of version bump is this release?" Options:

• "Patch (x.x.X)" - Bug fixes, documentation updates
• "Minor (x.X.0)" - New features, backwards compatible changes
• "Major (X.0.0)" - Breaking changes

Calculate the new version based on current version and selected bump type.

Step 8: Update package.json Version

Update the version in package.json:

npm version <patch|minor|major> --no-git-tag-version

Note: We use --no-git-tag-version because we'll handle git operations ourselves for more control.

Verify the new version:

node -p "require('./package.json').version"

Step 9: Commit and Push Version Bump

Commit the version change to git and push to remote before publishing. This ensures the working tree is clean for the publish step.

git add package.json
git commit -m "v{version}"
git push origin main

Step 10: Verify NPM Authentication

Check that the user is logged into NPM:

npm whoami

If not logged in, inform the user:

• "You need to log in to NPM first. Run npm login and authenticate."
• They should be logged into an account with publish access to @magnet-ai scope

Step 11: Confirm Before Publishing

Use AskUserQuestion for final confirmation:

Question: "Ready to publish version {new_version} to NPM?" Options:

• "Yes, publish now" - Proceed with publishing
• "No, abort" - Cancel the release

Step 12: Publish to NPM

Publish the package:

pnpm publish --access public

The prepublishOnly script will automatically run pnpm build before publishing.

Verify the publish succeeded by checking the npm registry:

npm view @magnet-ai/magnet-mcp-server version

Step 13: Create and Push Git Tag

Create a git tag for the release and push it:

git tag v{version}
git push origin v{version}

Step 14: Display Success Summary

Inform the user of the successful release:

• New version: {version}
• NPM package URL: https://www.npmjs.com/package/@magnet-ai/magnet-mcp-server
• Git tag: v{version}
• Commit pushed to: main

Error Handling

Dirty Git Working Directory

If git status shows uncommitted changes:

1. Inform the user they have uncommitted changes
2. Suggest: git stash to temporarily save changes, or git commit to commit them
3. Do not proceed until working directory is clean

Build Failures

If pnpm build fails:

1. Display the error output
2. Common issues:
   • TypeScript errors in source files
   • Missing dependencies (run pnpm install)
3. Do not proceed until build succeeds

Security Audit Failures

If the security audit detects issues:

Sensitive file in package:

1. Identify which file is being included (e.g., .env, .mcp.json)
2. Check if .gitignore has the correct entry
3. If using files field in package.json, ensure sensitive files aren't listed
4. Re-run npm pack --dry-run to verify fix

Hardcoded secrets found:

1. Identify the file and line containing the secret
2. Remove the hardcoded value
3. Replace with environment variable reference
4. Commit the fix before proceeding

Missing .gitignore entries:

1. Add the missing entries to .gitignore:

   .env*
   !.env.sample
   .mcp.json
   .claude/settings.local.json
   

2. Verify with npm pack --dry-run

NPM Not Logged In

If npm whoami fails:

1. Inform user they need to authenticate
2. Run npm login
3. Ensure they use an account with @magnet-ai scope access
4. Verify with npm whoami before proceeding

Publish Fails - 403 Forbidden

If publish returns 403:

1. User may not have publish permissions for @magnet-ai scope
2. Check: npm access ls-collaborators @magnet-ai/magnet-mcp-server
3. Contact a maintainer (nico-pal, zachcaceres, juliankrispel) for access

Tag Already Exists

If git tag fails because tag exists:

1. Verify the tag: git tag -l v{version}
2. If it exists from a failed previous attempt, delete it:
   • Local: git tag -d v{version}
   • Remote (if pushed): git push origin :refs/tags/v{version}
3. Re-run the tag creation

Push Rejected

If git push is rejected:

1. Someone may have pushed to main since you started
2. Run git pull --rebase origin main
3. Resolve any conflicts
4. Re-push

Examples

Example 1: Standard Patch Release

User: "Publish the latest bug fixes to npm"

Actions:

1. Verify git status is clean and on main
2. Pull latest changes
3. Run pnpm build and type check
4. Security audit: run npm pack --dry-run, verify no sensitive files, scan for hardcoded secrets
5. Show current version (e.g., 0.2.7)
6. Ask for version type → User selects "Patch"
7. Bump to 0.2.8
8. Commit and push: "v0.2.8"
9. Verify npm login
10. Confirm publishing
11. Run pnpm publish --access public
12. Tag v0.2.8 and push tag
13. Display success with NPM URL

Example 2: Minor Release with New Features

User: "We added new tools, let's release a new version"

Actions:

1. Verify git status and sync with remote
2. Build and validate
3. Security audit: verify package contents and scan for secrets
4. Show current version (e.g., 0.2.8)
5. Ask for version type → User selects "Minor"
6. Bump to 0.3.0
7. Commit and push version bump
8. Verify npm login
9. Confirm publishing
10. Publish to npm
11. Tag and push tag
12. Display success

Example 3: Recovering from Failed Publish

User: "The last publish failed halfway, can you help?"

Actions:

1. Check git status for any partial changes
2. Check if version was bumped: node -p "require('./package.json').version"
3. Check if version commit was pushed: git log origin/main --oneline -1
4. Check if tag exists: git tag -l v{version}
5. Check npm registry: npm view @magnet-ai/magnet-mcp-server version
6. Based on state:
   • If version is bumped but not committed: commit and push, then publish, then tag
   • If version is committed but not on npm: publish, then tag and push tag
   • If npm has the version but no tag: just create tag and push it
   • If nothing was done: start fresh

Notes

• Commit before publish - The version bump is committed and pushed before publishing to NPM. This ensures a clean working tree and avoids needing --no-git-checks.
• Security audit is mandatory - Never skip the security checks. A leaked API key requires rotation and can compromise user data.
• Always verify build before publishing - the prepublishOnly script runs build automatically, but checking first catches errors early
• Scoped package - @magnet-ai/magnet-mcp-server requires --access public for public visibility
• Version format - Uses semantic versioning (MAJOR.MINOR.PATCH)
• Git tags - Always prefixed with v (e.g., v0.2.8)
• Maintainers - Current npm maintainers: nico-pal, zachcaceres, juliankrispel
• No automated CI/CD - Publishing is manual via this skill
• Sensitive files to watch - .env, .mcp.json, settings.local.json, and any files with secrets/credentials/keys
