-# IDEAS.md - Gitclaw Evolution Roadmap
-
-> Brainstorming future features and improvements for gitclaw.
-> This is a living document — ideas may be implemented, modified, or discarded.
-
----
-
-## Core Features
-
-### 1. Configuration File Support
-**Description:** User configuration via `.gitclaw.toml` or `gitclaw.json`.
-
-**Use cases:**
-- Set default install directory
-- Store GitHub token
-- Preferred asset formats
-- Per-project config (`.gitclawrc` in repo root)
-
-**Example:**
-```toml
-# ~/.gitclaw.toml
-install_dir = "~/.local/bin"
-github_token = "ghp_..."
-
-[preferences]
-prefer_strip = true
-show_progress = true
-```
-
----
-
-### 2. Self-Update
-**Description:** Update gitclaw itself without manual reinstall.
-
-**Commands:**
-- `gitclaw self-update` — check and install latest release
-- `gitclaw self-update --check` — only check for updates
-- Optional: auto-check on startup (configurable)
-
----
-
-### 3. Dry Run Mode
-**Description:** Preview what would happen without downloading.
-
-**Commands:**
-- `gitclaw install --dry-run user/repo`
-- Shows: which asset selected, where it would install, etc.
-
-**Benefit:** CI-friendly, prevents surprises.
-
----
-
-### 4. Checksum Verification
-**Description:** Verify downloaded assets against published checksums.
-
-**Features:**
-- Auto-detect `.sha256`, `.sha512`, `.md5` files in release
-- Warn if checksum doesn't match
-- `gitclaw install --verify user/repo`
-
-**Security:** Prevents corrupted or malicious downloads.
-
----
-
-### 5. Parallel Installs
-**Description:** Install multiple packages concurrently.
-
-**Commands:**
-- `gitclaw install pkg1 pkg2 pkg3`
-- Downloads and extracts in parallel
-- Shared progress bar
-
-**Benefit:** Much faster bulk operations.
-
----
-
-### 6. Semver Range Support
-**Description:** Install versions matching constraints.
-
-**Syntax:**
-- `gitclaw install user/repo ">=1.0.0"`
-- `gitclaw install user/repo "^1.2.3"`
-- `gitclaw install user/repo "~1.2"`
-
-**Benefit:** Flexible version management without exact tags.
-
----
-
-### 7. Lockfile Support
-**Description:** Reproducible installs via `gitclaw.lock`.
-
-**Commands:**
-- `gitclaw lock` — generate lockfile from current installs
-- `gitclaw install --locked` — install from lockfile
-
-**Format:** TOML with exact versions and hashes.
-
----
-
-### 8. Shell Completions
-**Description:** Tab completion for shells.
-
-**Supported:** Bash, Zsh, Fish
-
-**Features:**
-- Complete package names from registry
-- Complete flags and subcommands
-- `gitclaw completions bash > /etc/bash_completion.d/gitclaw`
-
----
-
-## UX Improvements
-
-### 9. TUI Mode
-**Description:** Interactive terminal UI with `ratatui`.
-
-**Commands:**
-- `gitclaw --tui` or default when TTY detected
-- Browse releases visually
-- Preview assets before install
-- Filter/search interactively
-
----
-
-### 10. Asset Caching
-**Description:** Cache downloaded archives.
-
-**Location:** `~/.gitclaw/cache/`
-
-**Commands:**
-- Skip re-download if hash matches
-- `gitclaw cache clean` — clear cache
-- `gitclaw cache size` — show cache usage
-
----
-
-### 11. Local Installs
-**Description:** Project-local package installation.
-
-**Commands:**
-- `gitclaw install --local user/repo`
-- Installs to `./.gitclaw/bin/`
-- Ignores global registry
-
-**Use case:** CI/CD, reproducible environments.
-
----
-
-### 12. Package Aliases
-**Description:** Short names for frequently used packages.
-
-**Commands:**
-- `gitclaw alias rg BurntSushi/ripgrep`
-- `gitclaw install rg` → installs ripgrep
-- Store in config file
-
----
-
-### 13. Outdated Check
-**Description:** Show packages with available updates.
-
-**Commands:**
-- `gitclaw list --outdated`
-- Compares installed vs latest GitHub release
-- Shows current → latest version
-
----
-
-## Advanced Features
-
-### 14. Plugin System
-**Description:** Extend gitclaw with custom plugins.
-
-**Hooks:**
-- `pre-install` — custom validation
-- `post-install` — setup, symlinks
-- `pre-uninstall` — cleanup
-
-**Custom extractors:** Support non-standard archive formats.
-
----
-
-### 15. Release Channels
-**Description:** Install from specific channels.
-
-**Channels:**
-- `stable` — default
-- `nightly` — latest pre-release
-- `beta` — tagged beta versions
-
-**Commands:**
-- `gitclaw install user/repo --channel nightly`
-
----
-
-### 16. Export/Import
-**Description:** Share package lists between machines.
-
-**Commands:**
-- `gitclaw export > deps.toml`
-- `gitclaw import deps.toml`
-
-**Format:** TOML with package specs.
-
----
-
-## Platform-Specific
-
-### 17. Homebrew Integration
-**Description:** Detect and integrate with Homebrew on macOS.
-
-**Features:**
-- Warn if package already in Homebrew
-- Option to prefer Homebrew for certain packages
-
----
-
-### 18. Windows PATH Management
-**Description:** Automatically add to Windows PATH.
-
-**Features:**
-- Modify system or user PATH
-- Registry edits on Windows
-
----
-
-## Nice to Have
-
-### 19. Telemetry (Opt-in)
-**Description:** Anonymous usage statistics.
-
-**Data:**
-- Popular packages
-- Install success/failure rates
-- Platform distribution
-
-**Privacy:** Opt-in only, no personal data.
-
----
-
-### 20. Web Dashboard
-**Description:** Browser-based package browser.
-
-**Features:**
-- Search GitHub releases
-- View package popularity
-- One-click install (generates shell command)
-
----

-## Rejected Ideas
-
-> Ideas considered but rejected, with reasoning.
-
-| Idea | Reason |
-|------|--------|
-| Package signing | Too complex, checksums sufficient |
-| Auto-detect updates | Too noisy, explicit is better |
-| GUI application | Out of scope, TUI is sufficient |
-
----
-
-## Implementation Priority

-8. Lockfile support
-9. TUI mode
-
-### Phase 4 (Future)
-10. Plugin system
