Copilot 927f54feea feat: make git extension opt-in and remove --no-git at v0.10.0 (#2873)
* feat(init)!: make git extension opt-in and remove --no-git at v0.10.0

- Remove --no-git parameter from specify init command
- Remove git extension auto-installation from init flow
- Git repository initialization (git init) still runs when git is available
- Remove --no-git from all test invocations across the test suite
- Update docs to reflect opt-in git extension behavior
- Replace TestGitExtensionAutoInstall with TestGitExtensionOptIn tests

BREAKING CHANGE: specify init no longer auto-installs the git extension.
Use `specify extension add git` to install it explicitly.
The --no-git flag has been removed.

* refactor(scripts): remove git operations from core scripts

Git functionality is now entirely managed by the git extension.
Core scripts only handle directory-based feature creation and numbering.

- Remove has_git(), check_feature_branch(), git branch creation from core
- Simplify number detection to use only spec directory scanning
- Remove HAS_GIT output from get_feature_paths()
- Remove git remote fetching and branch querying
- Keep BRANCH_NAME output key for backward compatibility

* refactor: remove all git operations from core

- Remove is_git_repo() and init_git_repo() dead code from _utils.py
- Remove --branch-numbering from init command
- Remove git from 'specify check' (now extension-only)
- Update docs: git is optional prerequisite, check command description
- Fix tests to reflect no-git-in-core reality (fallback to main)

* refactor(scripts): remove directory scanning and branch fallback from core

Core scripts now resolve feature context exclusively from:
1. SPECIFY_FEATURE env var (set by git extension)
2. .specify/feature.json (persisted by specify command)

Removed find_feature_dir_by_prefix() and directory scanning heuristics —
these are the git extension's responsibility. Scripts error clearly when
no feature context is available.

* feat: introduce feature_numbering, deprecate branch_numbering in init-options

- specify command template now reads feature_numbering (preferred) with
  fallback to branch_numbering (deprecated) from init-options.json
- Git extension reads git-config.yml > feature_numbering > branch_numbering
- init now writes feature_numbering: sequential to init-options.json
- Deprecation warning emitted when branch_numbering is used as fallback

* fix: remove trailing whitespace in common.ps1

* feat(scripts): persist SPECIFY_FEATURE_DIRECTORY env var to feature.json

When SPECIFY_FEATURE_DIRECTORY is set, get_feature_paths() now writes the
value to .specify/feature.json so future sessions without the env var can
still resolve the feature directory. The write is idempotent — it skips
when the file already contains the same value.

* fix: address review feedback — error messages and docs

- Update error messages in common.sh and common.ps1 to reference
  SPECIFY_FEATURE_DIRECTORY instead of SPECIFY_FEATURE (which no longer
  resolves feature directories)
- Fix get_current_branch comment (returns empty string, not error)
- Update upgrade.md to reference SPECIFY_FEATURE_DIRECTORY with correct
  example paths
- Update local-development.md troubleshooting: replace stale 'Git step
  skipped' row with actionable git extension guidance

* fix(scripts): harden feature.json persistence

- Use json_escape in printf fallback when jq is unavailable (common.sh)
- Replace utf8NoBOM encoding with UTF8Encoding($false) for PowerShell
  5.1 compatibility (common.ps1)

* refactor(scripts): remove dead feature_json_matches_feature_dir functions

These guards are no longer needed since the branch-name validation they
protected against has been removed from check-prerequisites.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* refactor(git-ext): rename create-new-feature to create-new-feature-branch

The git extension's script only creates the git branch — rename it to
reflect that responsibility. The core create-new-feature.sh/.ps1 handles
feature directory creation and feature.json persistence.

Also includes fixes from review feedback:
- common.sh: _persist_feature_json uses json_escape fallback
- common.ps1: Save-FeatureJson uses UTF8Encoding for PS 5.1 compat
- common.ps1: case-sensitive path stripping on non-Windows
- create-new-feature.sh/ps1: output both SPECIFY_FEATURE and
  SPECIFY_FEATURE_DIRECTORY
- setup-tasks.sh: fix stale 'Validate branch' comment

* fix(tests): update references to renamed git extension scripts

* fix(tests): remove duplicate EXT_CREATE_FEATURE assignments

# Git Branching Workflow Extension
Git repository initialization, feature branch creation, numbering (sequential/timestamp), validation, remote detection, and auto-commit for Spec Kit.
## Overview
This extension provides Git operations as an optional, self-contained module. It manages:
- **Repository initialization** with configurable commit messages
- **Feature branch creation** with sequential (`001-feature-name`) or timestamp (`20260319-143022-feature-name`) numbering
- **Branch validation** to ensure branches follow naming conventions
- **Git remote detection** for GitHub integration (e.g., issue creation)
- **Auto-commit** after core commands (configurable per-command with custom messages)
## Commands
| Command | Description |
|---------|-------------|
| `speckit.git.initialize` | Initialize a Git repository with a configurable commit message |
| `speckit.git.feature` | Create a feature branch with sequential or timestamp numbering |
| `speckit.git.validate` | Validate current branch follows feature branch naming conventions |
| `speckit.git.remote` | Detect Git remote URL for GitHub integration |
| `speckit.git.commit` | Auto-commit changes (configurable per-command enable/disable and messages) |
## Hooks
| Event | Command | Optional | Description |
|-------|---------|----------|-------------|
| `before_constitution` | `speckit.git.initialize` | No | Init git repo before constitution |
| `before_specify` | `speckit.git.feature` | No | Create feature branch before specification |
| `before_clarify` | `speckit.git.commit` | Yes | Commit outstanding changes before clarification |
| `before_plan` | `speckit.git.commit` | Yes | Commit outstanding changes before planning |
| `before_tasks` | `speckit.git.commit` | Yes | Commit outstanding changes before task generation |
| `before_implement` | `speckit.git.commit` | Yes | Commit outstanding changes before implementation |
| `before_checklist` | `speckit.git.commit` | Yes | Commit outstanding changes before checklist |
| `before_analyze` | `speckit.git.commit` | Yes | Commit outstanding changes before analysis |
| `before_taskstoissues` | `speckit.git.commit` | Yes | Commit outstanding changes before issue sync |
| `after_constitution` | `speckit.git.commit` | Yes | Auto-commit after constitution update |
| `after_specify` | `speckit.git.commit` | Yes | Auto-commit after specification |
| `after_clarify` | `speckit.git.commit` | Yes | Auto-commit after clarification |
| `after_plan` | `speckit.git.commit` | Yes | Auto-commit after planning |
| `after_tasks` | `speckit.git.commit` | Yes | Auto-commit after task generation |
| `after_implement` | `speckit.git.commit` | Yes | Auto-commit after implementation |
| `after_checklist` | `speckit.git.commit` | Yes | Auto-commit after checklist |
| `after_analyze` | `speckit.git.commit` | Yes | Auto-commit after analysis |
| `after_taskstoissues` | `speckit.git.commit` | Yes | Auto-commit after issue sync |
## Configuration
Configuration is stored in `.specify/extensions/git/git-config.yml`:
```yaml
# Branch numbering strategy: "sequential" or "timestamp"
branch_numbering: sequential
# Custom commit message for git init
init_commit_message: "[Spec Kit] Initial commit"
# Auto-commit per command (all disabled by default)
# Example: enable auto-commit after specify
auto_commit:
default: false
after_specify:
enabled: true
message: "[Spec Kit] Add specification"
```
## Installation
```bash
# Install the bundled git extension (no network required)
specify extension add git
```
## Disabling
```bash
# Disable the git extension (spec creation continues without branching)
specify extension disable git
# Re-enable it
specify extension enable git
```
## Graceful Degradation
When Git is not installed or the directory is not a Git repository:
- Spec directories are still created under `specs/`
- Branch creation is skipped with a warning
- Branch validation is skipped with a warning
- Remote detection returns empty results
## Scripts
The extension bundles cross-platform scripts:
- `scripts/bash/create-new-feature-branch.sh` — Bash implementation (branch creation only)
- `scripts/bash/git-common.sh` — Shared Git utilities (Bash)
- `scripts/powershell/create-new-feature-branch.ps1` — PowerShell implementation (branch creation only)
- `scripts/powershell/git-common.ps1` — Shared Git utilities (PowerShell)
