What problem does it solve? Contributors to the KnowledgeVault (RAGAPPv3) repository often fail CI or write inconsistent commits because they do not know the repo's exact conventions. This Skill provides the actionable checklist for branching, committing, running the four CI gates locally, and opening PRs so contributions pass review on the first attempt. ## Core Features & Use Cases - Branch and Commit Conventions: Enforces branching from latest origin/master with prefixed slugs and Conventional Commits format (type(scope): lowercase description). - Local CI Gate Reproduction: Lists exact commands for the four CI jobs — Backend (ruff, pytest subset on Python 3.11), Frontend (typecheck, lint, vitest, build), Quality contracts (check_config_contract.py, check_pr_scope_drift.py, check_sast_baseline.py), and SAST (bandit baseline diff). - PR Workflow Guidance: Directs draft PRs against master with Summary and Test plan sections, deferring publication mechanics to the commit-pr skill. - Use Case: Before pushing a bug fix, an agent loads this Skill to create a fix/ branch, run ruff and the targeted pytest subset, verify the frontend lint zero-warning gate, and open a draft PR with the required body sections. ## Quick Start Load the contributing skill and walk me through creating a branch, running all CI gates locally, and opening a draft PR for my fix to the tags endpoint.
