PyPI Publishing with Doppler (Local-Only) Skill

PyPI Publishing with Doppler (Local-Only)

When to Use This Skill

Use this skill when:

Publishing Python packages to PyPI from local machine
Setting up Doppler for PyPI token management
Creating local publish scripts with CI detection guards
Validating repository ownership before release

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:

GitHub Actions: Automated versioning ONLY (tags, releases, CHANGELOG)
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:

/usr/bin/env bash << 'DOPPLER_EOF'
# 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
DOPPLER_EOF

Prerequisites

One-Time Setup

Install Doppler CLI:
```
brew install dopplerhq/cli/doppler
```
Authenticate with Doppler:
```
doppler login
```
Verify access to claude-config project:
```
doppler whoami
doppler projects
```

PyPI Token Setup

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)

Store token in Doppler:

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

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:

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

Complete Release Workflow

Step 1: Development & Commit (Conventional Commits):

git add .
git commit -m "feat: add new feature"  # MINOR bump
git push origin main

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

GitHub Actions automatically: analyzes commits, determines next version, updates pyproject.toml/package.json, generates CHANGELOG, creates git tag, creates GitHub release.

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

Step 3: Local PyPI Publishing (30 seconds):

git pull origin main
./scripts/publish-to-pypi.sh

Using Bundled Script (Recommended)

/usr/bin/env bash << 'GIT_EOF'
# 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
GIT_EOF

Bundled script features: CI detection guards, repository verification, Doppler integration, build + publish + verify workflow, clear error messages.

Manual Publishing (Advanced)

For manual publishing without the canonical script:

/usr/bin/env bash << 'CONFIG_EOF'
# 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
CONFIG_EOF

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

Validation History

2025-12-03: Refactored to discovery-first, environment-agnostic approach
- discover_uv() checks PATH, direct installs, version managers (priority order)
- Supports: curl install, Homebrew, cargo, mise, asdf - doesn't force any method
2025-11-22: Created with ADR-0027 alignment (workspace-wide local-only policy)
Validation: CI detection guards tested, Doppler integration verified

Last Updated: 2025-12-03 Policy: Workspace-wide local-only PyPI publishing (ADR-0027) Supersedes: None (created with ADR-0027 compliance from start)
