_shared/sdd-artifacts/SESSION.md; load session-state for$Cwd - If the relevant gate is not approved: STOP - ask user (pt-BR) - do NOT Write/Shell
- SDD/develop skills: after ONE step/task, STOP session - handoff only
- This skill body is English; user-facing prompts may be (pt-BR)
Step -1 - Gate check (report in chat before continuing)
Gate check:
[ ] guardrails.mdc read
[ ] SESSION.md read; session-state loaded
[ ] User confirmed current action (sim)
-> If any unchecked: STOP
Trigger
Use when user asks for /python-developer, python fix, or a small isolated Python implementation.
Outcome
Working Python code and tests in the target workspace, validated with pytest/build, with optional handoff to /commit.
When to escalate to SDD
Recommend sdd-spec -> sdd-plan -> sdd-develop for schema changes, new services, or 10+ file changes.

0. Workspace
Confirm Python project (pyproject.toml, requirements.txt, or .py layout). Summarize acceptance.
1. Guidelines
Load only required Python guidelines (PEP-8, project style).
2. Branch
Use feature/<slug> or feat/<id>.
3. Micro-plan
Define 3-7 concrete tasks; checkpoint context at >= 40%.
4. Implement
Use virtual environment (venv or uv). Match existing package layout.
5. Tests
pytest for changed behavior.
6. Validate
pytest
Add build/lint steps if configured (ruff, mypy, etc.).
7. Handoff
Offer /commit. Do not commit automatically.
Must not
- Auto-commit or auto-PR
- Leave AI traces in code or identifiers
