_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
[ ] PIPELINE.md read (SDD skills only)
[ ] User confirmed current action (sim)
-> If any unchecked: STOP
Skill: python-developer
Trigger
Invoke when the user asks for: /python-developer, python fix, implement FastAPI/Flask feature, or for small Python work that does not need a full PRD/PLAN cycle.
Outcome
Working Python code and tests in the open workspace: pytest (and project lint/type checks when configured) green, on a valid feature branch, with optional commit handoff. Supports FastAPI and Flask — not a FastAPI-only skill. Does not replace SDD for multi-step or cross-repo features.

Do not preload other stack guideline packs or corporate pipeline docs. Load only the python-guidelines rows needed for the current task (FastAPI and/or Flask and pytest as applicable). MUST NOT glob architecture/** — load hub + one principles style from ARCH/CONTINUITY (brownfield: discover-first if style omitted).
Never by default: do not preload all references/*.md. do not preload other stack guideline packs. Load only Python rows needed for the current task. Do not dump full stack guideline packs or memory-bank. Load one section per Process step (SKILL-REFERENCE-RETRIEVAL.md).
Reference routing
| Situation | Path |
|---|---|
| Scope / SDD escalation / design brief | references/scope.md |
| Implement flow | references/execute-flow.md |
| Must not (full) | references/must-not.md |
Process
Read references/<section>.md for procedural detail — not full reference.md.
Step -1b - Caveman Mode (Full cap)
- Read
{{SDD_ROOT}}/preferences.json(create{ "caveman_mode": false, "caveman_level": "full" }if missing). - If
caveman_modeis false: continue without compression. - If true: load
{{TOOLKIT_ROOT}}/skills/_shared/caveman/CAVEMAN.md; apply Full participation cap + prefscaveman_level(Lite skills never escalate); show once:[Caveman] Modo ativo (respostas compactas, level={effective}). Digite caveman off para desativar. - Honor

CAVEMAN.md.
0. Scope
Follow references/scope.md (SDD escalation, design brief / host detection when present).
1. Execute
Follow references/execute-flow.md (subagent-first, workspace → guidelines → branch → implement → tests → handoff).
Must not
Enforce the full list in references/must-not.md. Critical: no guideline dumps into children; no auto-commit; lazy-load stack guidelines only — never dump full packs or memory-bank.
