Doppler Credential Workflows

Quick Reference

When to use this skill:

• Publishing Python packages to PyPI
• Rotating AWS access keys
• Managing credentials across multiple services
• Troubleshooting authentication failures (403, InvalidClientTokenId)
• Setting up Doppler credential injection patterns
• Multi-token/multi-account strategies

Core Pattern: Doppler CLI

Standard Usage:

doppler run --project <project> --config <config> --command='<command>'

Why --command flag:

• Official Doppler pattern (auto-detects shell)
• Ensures variables expand AFTER Doppler injects them
• Without it: shell expands $VAR before Doppler runs → empty string

---

Quick Start Examples

PyPI Publishing

doppler run --project claude-config --config dev \
  --command='uv publish --token "$PYPI_TOKEN"'

AWS Operations

doppler run --project aws-credentials --config dev \
  --command='aws s3 ls --region $AWS_DEFAULT_REGION'

---

Best Practices

1. Always use --command flag for credential injection
2. Use project-scoped tokens (PyPI) for better security
3. Rotate credentials regularly (90 days recommended)
4. Document with Doppler notes: doppler secrets notes set <SECRET> "<note>"
5. Use stdin for storing secrets: echo -n 'secret' | doppler secrets set
6. Test injection before using: echo ${#VAR} to verify length
7. Multi-token naming: SERVICE_TOKEN_{ABBREV} for clarity

Using mise [env] for Local Development (Recommended)

For local development, mise [env] provides a simpler alternative to doppler run:

# .mise.toml
[env]
# Fetch from Doppler with caching for performance
PYPI_TOKEN = "{{ cache(key='pypi_token', duration='1h', run='doppler secrets get PYPI_TOKEN --project claude-config --config prd --plain') }}"

# For GitHub multi-account setups
GH_TOKEN = "{{ read_file(path=env.HOME ~ '/.claude/.secrets/gh-token-accountname') | trim }}"

When to use mise [env]:

• Per-directory credential configuration
• Multi-account GitHub setups
• Credentials that persist across commands (not session-scoped)

When to use doppler run:

• CI/CD pipelines
• Single-command credential scope
• When you want credentials auto-cleared after command

See mise-configuration skill for complete patterns.

PyPI Publishing Policy

For PyPI publishing, see pypi-doppler skill for LOCAL-ONLY workspace policy.

Do NOT configure PyPI publishing in GitHub Actions or CI/CD pipelines.
