Bootstrap opentelemetry-python-genai repo

[MikeGoldsmith]

Tracking issue for infrastructure and CI setup needed when the opentelemetry-python-genai repo is created. This covers migrating the GenAI instrumentation packages out of opentelemetry-python-contrib into their own repository.

Packages to migrate

• opentelemetry-instrumentation-anthropic
• opentelemetry-instrumentation-claude-agent-sdk
• opentelemetry-instrumentation-google-genai
• opentelemetry-instrumentation-langchain
• opentelemetry-instrumentation-openai-agents-v2
• opentelemetry-instrumentation-openai-v2
• opentelemetry-util-genai

Repo infrastructure

Licensing & compliance

• LICENSE file (Apache-2.0)
• SPDX license headers (# SPDX-License-Identifier: Apache-2.0) on all Python files
• CI check for SPDX headers (port scripts/check_license_header.py from contrib)

CI / GitHub Actions

• Lint workflow (ruff, mypy, SPDX check)
• Test workflow per package (consider generating from templates like contrib does with tox -e generate-workflows)
• CodeQL / security scanning
• FOSSA or equivalent license compliance check

Changelog management (towncrier)

• Towncrier config in root pyproject.toml
• Changelog fragment directories (.changelog/ at root; evaluate per-package .changelog/ later)
• Changelog CI check — require fragment on PRs to main, allow "Skip Changelog" label bypass
• Changelog preview step in CI (towncrier build --draft)
• Pin towncrier version
• Changelog Jinja2 template (port from contrib or simplify)

PR automation

• GitHub Action to add PRs to a project board on opened / reopened / ready_for_review (port add-to-project.yml)
  • Needs GitHub App (otelbot) or token with project write access
  • Filter out draft PRs
• PR labeler (auto-label by package path)
• Component owners auto-assignment (port component-owners.yml workflow + config)
• PR template

GitHub board & dashboard

• Create new GitHub Project board for the repo
• Automate adding issues and PRs to the board
• Dashboard views: open PRs by package, issues by label, stale items

Labels

• bug, enhancement, documentation
• Skip Changelog
• prepare-release
• Stale
• Add others (e.g., per-package labels, dependencies) as needed later

Other

• CODEOWNERS file
• AGENTS.md (port from contrib instrumentation-genai/AGENTS.md and root)
• Copilot / Claude review instructions (port .github/instructions/ from contrib)
• Issue templates (bug report, feature request)
• CONTRIBUTING.md with GenAI-specific guidelines
• RELEASING.md with release process
• Stale issue/PR bot
