name: pypi-doppler description: LOCAL-ONLY PyPI publishing with Doppler credential management. Use when publishing to PyPI from LOCAL machine ONLY. NEVER use in CI/CD pipelines. Workspace-wide policy enforces local publishing via scripts/publish-to-pypi.sh with CI detection guards.

PyPI Publishing with Doppler (Local-Only)

⚠️ WORKSPACE-WIDE POLICY: LOCAL-ONLY PUBLISHING

This skill supports LOCAL machine publishing ONLY.

FORBIDDEN

❌ Publishing from GitHub Actions ❌ Publishing from any CI/CD pipeline (GitHub Actions, GitLab CI, Jenkins, CircleCI) ❌ publishCmd in semantic-release configuration ❌ Building packages in CI (uv build in prepareCmd) ❌ Storing PyPI tokens in GitHub secrets

REQUIRED

✅ Use scripts/publish-to-pypi.sh on local machine ✅ CI detection guards in publish script ✅ Manual approval before each release ✅ Doppler credential management (no plaintext tokens) ✅ Repository verification (prevents fork abuse)

Rationale

• Security: No long-lived PyPI tokens in GitHub secrets
• Speed: 30 seconds locally vs 3-5 minutes in CI
• Control: Manual approval step before production release
• Flexibility: Centralized credential management via Doppler

See: ADR-0027, docs/development/PUBLISHING.md

---

Overview

This skill provides local-only PyPI publishing using Doppler for secure credential management. It integrates with the workspace-wide release workflow where:

1. GitHub Actions: Automated versioning ONLY (tags, releases, CHANGELOG)
2. Local Machine: Manual PyPI publishing with Doppler credentials

Bundled Scripts

Script	Purpose
scripts/publish-to-pypi.sh	Local PyPI publishing with CI detection guards

Usage: Copy to your project's scripts/ directory:

# Environment-agnostic path
PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$HOME/.claude/plugins/marketplaces/cc-skills/plugins/itp}"
cp "$PLUGIN_DIR/skills/pypi-doppler/scripts/publish-to-pypi.sh" scripts/
chmod +x scripts/publish-to-pypi.sh

---

Prerequisites

One-Time Setup

1. Install Doppler CLI:

   brew install dopplerhq/cli/doppler
   

2. Authenticate with Doppler:

   doppler login
   

3. Verify access to claude-config project:

   doppler whoami
   doppler projects
   

PyPI Token Setup

1. Create PyPI API token:

   • Visit: https://pypi.org/manage/account/token/
   • Enable 2FA if not already enabled (required since 2024)
   • Create token with scope: "Entire account" or specific project
   • Copy token (starts with pypi-AgEIcHlwaS5vcmc..., ~180 characters)

2. Store token in Doppler:

   doppler secrets set PYPI_TOKEN='pypi-AgEIcHlwaS5vcmc...' \
     --project claude-config \
     --config prd
   

3. Verify token stored:

   doppler secrets get PYPI_TOKEN \
     --project claude-config \
     --config prd \
     --plain

Publishing Workflow

MANDATORY: Verify Version Increment Before Publishing

Pre-publish validation: Before publishing to PyPI, verify that the version has incremented from the previous release. Publishing without a version increment is invalid and wastes resources.

Autonomous check sequence:

1. Compare local pyproject.toml version against latest PyPI version
2. If versions match → STOP - do not proceed with publishing
3. Inform user: "Version not incremented. Run semantic-release first or verify commits include feat: or fix: types."

Why this matters: PyPI rejects duplicate versions, but more importantly, users and package managers rely on version increments to detect updates. A release workflow that doesn't increment version is broken.

Complete Release Workflow

Step 1: Development & Commit (Conventional Commits):

# Make your changes
git add .

# Commit with conventional format (determines version bump)
git commit -m "feat: add new feature"  # MINOR bump

# Push to main
git push origin main

Step 2: Automated Versioning (GitHub Actions - 40-60s):

GitHub Actions workflow automatically:

• ✅ Analyzes commits using @semantic-release/commit-analyzer
• ✅ Determines next version (e.g., v7.1.0)
• ✅ Updates pyproject.toml, package.json versions
• ✅ Generates and updates CHANGELOG.md
• ✅ Creates git tag (v7.1.0)
• ✅ Creates GitHub release with release notes
• ✅ Commits changes back to repo with [skip ci] message

⚠️ PyPI publishing does NOT happen here (by design - see ADR-0027)

Step 3: Local PyPI Publishing (30 seconds):

After GitHub Actions completes, publish to PyPI locally:

# Pull the latest release commit
git pull origin main

# Publish to PyPI (uses pypi-doppler skill)
./scripts/publish-to-pypi.sh

Expected output:

🚀 Publishing to PyPI (Local Workflow)
======================================

🔐 Step 0: Verifying Doppler credentials...
   ✅ Doppler token verified

📥 Step 1: Pulling latest release commit...
   Current version: v7.1.0

Publishing Command (Local Machine Only)

CRITICAL: This command must ONLY run on your local machine, NEVER in CI/CD.

Using Bundled Script (Recommended)

# First time: copy script from skill to your project (environment-agnostic)
PLUGIN_DIR="${CLAUDE_PLUGIN_ROOT:-$HOME/.claude/plugins/marketplaces/cc-skills/plugins/itp}"
cp "$PLUGIN_DIR/skills/pypi-doppler/scripts/publish-to-pypi.sh" scripts/
chmod +x scripts/publish-to-pypi.sh

# After semantic-release creates GitHub release
git pull origin main

# Publish using local copy of bundled script
./scripts/publish-to-pypi.sh

Bundled script features:

• ✅ CI detection guards (blocks if CI=true)
• ✅ Repository verification (prevents fork abuse)
• ✅ Doppler integration (PYPI_TOKEN retrieval)
• ✅ Build + publish + verify workflow
• ✅ Clear error messages

Manual Publishing (Advanced)

For manual publishing without the canonical script:

# Retrieve token from Doppler
PYPI_TOKEN=$(doppler secrets get PYPI_TOKEN \
  --project claude-config \
  --config prd \
  --plain)

# Build package
uv build

# Publish to PyPI
UV_PUBLISH_TOKEN="${PYPI_TOKEN}" uv publish

⚠️ WARNING: Manual publishing bypasses CI detection guards and repository verification. Use canonical script unless you have a specific reason not to.

---

CI Detection Enforcement

The canonical publish script (scripts/publish-to-pypi.sh) includes CI detection guards to prevent accidental execution in CI/CD pipelines.

Environment Variables Checked

• $CI - Generic CI indicator
• $GITHUB_ACTIONS - GitHub Actions
• $GITLAB_CI - GitLab CI
• $JENKINS_URL - Jenkins
• $CIRCLECI - CircleCI

Behavior

If any CI variable detected, script exits with error:

❌ ERROR: This script must ONLY be run on your LOCAL machine

   Detected CI environment variables:
   - CI: true
   - GITHUB_ACTIONS: <not set>
   ...

   This project enforces LOCAL-ONLY PyPI publishing for:
   - Security: No long-lived PyPI tokens in GitHub secrets
   - Speed: 30 seconds locally vs 3-5 minutes in CI
   - Control: Manual approval step before production release

   See: docs/development/PUBLISHING.md (ADR-0027)

Testing CI Detection

# This should FAIL with error message
CI=true ./scripts/publish-to-pypi.sh

# Expected: ❌ ERROR: This script must ONLY be run on your LOCAL machine

Credential Management

Doppler Configuration

Project: claude-config Configs: prd (production), dev (development) Secret Name: PYPI_TOKEN

Token Format

Valid PyPI token format:

• Starts with: pypi-AgEIcHlwaS5vcmc
• Length: ~180 characters
• Example: pypi-AgEIcHlwaS5vcmcCJGI4YmNhMDA5LTg...

Token Permissions

Account-wide token (recommended):

• Can publish to all projects under your account
• Simpler management
• One token for all repositories

Project-scoped token:

• Can only publish to specific project
• More restrictive
• Separate token per project needed

Token Rotation

# 1. Create new token on PyPI
# Visit: https://pypi.org/manage/account/token/

# 2. Update Doppler
doppler secrets set PYPI_TOKEN='new-token' \
  --project claude-config \
  --config prd

# 3. Verify new token works
doppler secrets get PYPI_TOKEN \
  --project claude-config \
  --config prd \
  --plain

# 4. Test publish (dry-run not available, use TestPyPI)
# See: Troubleshooting → TestPyPI Testing

---

Troubleshooting

Issue: "PYPI_TOKEN not found in Doppler"

Symptom: Script fails at Step 0

Fix:

# Verify token exists
doppler secrets --project claude-config --config prd | grep PYPI_TOKEN

# If missing, get new token from PyPI
# Visit: https://pypi.org/manage/account/token/
# Create token with scope: "Entire account" or specific project

# Store in Doppler
doppler secrets set PYPI_TOKEN='your-token' \
  --project claude-config \
  --config prd

Issue: "403 Forbidden from PyPI"

Symptom: Script fails at Step 4 with authentication error

Root Cause: Token expired or invalid (PyPI requires 2FA since 2024)

Fix:

1. Verify 2FA enabled on PyPI account
2. Create new token: https://pypi.org/manage/account/token/
3. Update Doppler: doppler secrets set PYPI_TOKEN='new-token' --project claude-config --config prd
4. Retry publish

Issue: "Script blocked with CI detection error"

Symptom:

❌ ERROR: This script must ONLY be run on your LOCAL machine
Detected CI environment variables:
- CI: true

Root Cause: Running in CI environment OR CI variable set locally

Fix:

# Check if CI variable set in your shell
env | grep CI

# If set, unset it
unset CI
unset GITHUB_ACTIONS

# Retry publish
./scripts/publish-to-pypi.sh

Expected behavior: This is INTENTIONAL - script should ONLY run locally.

Issue: "Version not updated in pyproject.toml"

Symptom: Local publish uses old version number

Root Cause: Didn't pull latest release commit from GitHub

Fix:

# Always pull before publishing
git pull origin main

# Verify version updated
grep '^version = ' pyproject.toml

# Retry publish
./scripts/publish-to-pypi.sh

Issue: "uv package manager not found"

Symptom: Script fails at startup before any steps

Root Cause: uv not installed or not discoverable

How the script discovers uv (in priority order):

1. Already in PATH (Homebrew, direct install, shell configured)
2. Common direct install locations (~/.local/bin/uv, ~/.cargo/bin/uv, /opt/homebrew/bin/uv)
3. Version managers as fallback (mise, asdf)

Fix: Install uv using any method:

# Official installer (recommended)
curl -LsSf https://astral.sh/uv/install.sh | sh

# Homebrew
brew install uv

# Cargo
cargo install uv

# mise (if you use it)
mise use uv@latest

The script doesn't force any particular installation method.

Issue: Script Hangs with No Output

Symptom: Script starts but produces no output, eventually times out

Root Cause: Script sources ~/.zshrc or ~/.bashrc which waits for interactive input

Fix: Never source shell config files in scripts. The bundled script uses:

# CORRECT - safe for non-interactive shells
eval "$(mise activate bash 2>/dev/null)" || true

# WRONG - hangs in non-interactive shells
source ~/.zshrc

TestPyPI Testing

To test publishing workflow without affecting production:

1. Get TestPyPI token:

   • Visit: https://test.pypi.org/manage/account/token/
   • Create token

2. Store in Doppler (separate key):

   doppler secrets set TESTPYPI_TOKEN='your-test-token' \
     --project claude-config \
     --config prd
   

3. Modify publish script temporarily:

   # In scripts/publish-to-pypi.sh, change:
   uv publish --token "${PYPI_TOKEN}"
   
   # To:
   TESTPYPI_TOKEN=$(doppler secrets get TESTPYPI_TOKEN --plain)
   uv publish --repository testpypi --token "${TESTPYPI_TOKEN}"
   

4. Test publish:

   ./scripts/publish-to-pypi.sh
   

5. Verify on TestPyPI:

   • https://test.pypi.org/project/your-package/

6. Restore script to production configuration
