Pre-Commit Workflow Management Skill

This skill explains how to maintain, configure, and execute the intelligent pre-commit hook workflow in the **GitHub Backup Automation System** monorepo.

1. Branch-First Development

IMPORTANT

**CREATE A LOCAL BRANCH FIRST**: Always start by creating a local branch from `main`: ```bash git switch -c MishraShardendu22/main/<feature-name> ``` Never make changes directly on `main`.

2. Pre-Commit Architecture

The pre-commit workflow lives in `.githooks/pre-commit` and is tracked directly in version control.

Staged Changes Detected (git diff --cached)
  │
  ├── Only Go files changed ───────► Run Go formatting, vet, tests, build (~1-2s)
  ├── Only Python files changed ───► Run Pyright typecheck, agent test suite (~3-4s)
  ├── Only Frontend files changed ─► Run Biome lint, Next.js build (~10-12s)
  ├── Only Documentation changed ──► Fast-path bypass (<0.2s)
  └── Global / Config / Manual ────► Full monorepo validation gate (~20s)

2. Key Features

  • **Selective Staged-File Execution**: Avoids unnecessary work by only running checks relevant to the files staged for the commit.
  • **Fast-Path for Documentation**: Commits containing only markdown (`*.md`), text (`*.txt`), or asset files skip expensive build and test pipelines.
  • **Subshell Directory Isolation**: Every check runs in a subshell `(cd "${REPO_ROOT}" && ...)` to prevent current working directory drift.
  • **Fail-Fast with Remediation**: Aborts immediately on failure and outputs exact commands needed to fix the problem.
  • **Zero External Runtime Dependencies**: Implemented in portable POSIX bash, requiring no npm wrapper packages (like Husky) at the repository root.

    • 3. Operations & Maintenance Runbook

    Activating the Hook Locally

    bash
    make hooks-install
# Or: ./scripts/install-hooks.sh

    Manually Running Pre-Commit Gate

    bash
    make pre-commit

    Bypass Flags (Emergency Only)

    bash
    # Skip tests for quick drafts
SKIP_TESTS=1 git commit -s -S -m "chore: draft"

# Skip builds for lightweight edits
SKIP_BUILDS=1 git commit -s -S -m "fix: comment"

# Force full validation across all subsystems
PRECOMMIT_ALL=1 git commit -s -S -m "feat: core change"
