Refactor and harden all shell wrapper scripts across the module and assets repositories.
# Problem
The current `.sh` and `.ps1` wrapper scripts do not properly forward arbitrary CLI arguments to the underlying toolkit commands.
Example:
- `--verbose`
- `--debug`
- `--dry-run`
- `--config`
- `--dataset`
- `--force`
- future flags
Many wrappers only support fixed commands or partially forward arguments.
Additionally, after recent refactors — including:
- YAML configuration migration
- configuration hardening
- toolkit restructuring
- command refactors
- repository abstraction changes
— several wrapper scripts are now outdated and no longer correctly reflect the current toolkit behavior.
Example of a recent error produced:
```bash
$ ./build-haks.sh

# Goal
Make all wrapper scripts:
- consistent
- argument-transparent
- future-safe
- deterministic
- repository-agnostic where possible
# Core requirements
## Global argument forwarding
All wrappers must forward arbitrary arguments transparently to the underlying command.
Examples:
```bash
./run-tool.sh build-haks --verbose
./run-tool.sh music build --dataset westgate --dry-run
./extract-module.sh --debug --force
```
Must correctly pass all additional arguments through unchanged.
PowerShell wrappers must behave equivalently:
```powershell
.\run-tool.ps1 build-haks --verbose
```
No wrapper should:
- silently swallow arguments
- hardcode known flags only
- require updating for every new CLI option
- partially parse arguments unless absolutely necessary
Wrappers should behave as thin passthrough layers.
# Wrapper audit
Audit all `.sh` and `.ps1` scripts in:
- module repositories
- assets repositories
- toolkit-related repositories
Identify wrappers that:
- no longer match current toolkit commands
- reference outdated config paths
- reference old JSON config names
- assume old directory layouts
- assume deprecated commands
- hardcode obsolete arguments
- bypass the new normalized YAML config system
- duplicate logic now handled in the toolkit
# Consistency requirements
All wrappers should follow consistent conventions:
- argument forwarding
- environment setup
- working directory resolution
- config resolution
- logging behavior
- error handling
- exit code propagation
- path normalization
- quoting/escaping
# Behavior requirements
## Argument passthrough
Shell wrappers should use safe passthrough semantics.
Examples:
- Bash: `"$@"`
- PowerShell: `@args`
Arguments must preserve:
- ordering
- quoting
- spaces
- special characters
## Exit codes
Wrappers must propagate underlying command exit codes correctly.
No swallowing failures.
## Logging
Wrappers should:
- print concise execution summaries
- show the underlying toolkit command being executed
- optionally support wrapper-level debug logging
- avoid duplicating toolkit logs
## Configuration awareness
Wrappers must support:
- YAML config paths
- overridden config locations
- repository-local config resolution
- future config expansion
No wrapper should assume:
- `config.json`
- fixed build paths
- fixed repository names
- fixed datasets
- fixed HAK names
# Repository hardening alignment
Wrappers must align with the broader configuration hardening effort:
- no repository-specific hardcoding
- no hidden defaults
- no implicit assumptions
- no duplicated business logic
Wrappers should invoke toolkit functionality, not reimplement it.
# Desired architecture
Wrappers should become:
- thin launchers
- environment bootstrap layers
- argument passthrough adapters
The toolkit itself should contain:
- validation
- command parsing
- config loading
- business logic
- deterministic behavior
# Cross-platform behavior
Ensure `.sh` and `.ps1` wrappers behave equivalently where possible.
Validate:
- quoting
- argument escaping
- relative path handling
- environment variable handling
- error propagation
- working directory behavior
# Migration tasks
1. Inventory all wrappers.
2. Classify active vs obsolete wrappers.
3. Update wrappers to support transparent argument forwarding.
4. Remove outdated assumptions.
5. Align wrappers with YAML config loading.
6. Update docs/examples/help text.
7. Add regression tests.
8. Ensure compatibility with current toolkit commands.
9. Remove duplicated wrapper logic where possible.
10. Consolidate shared wrapper behavior if appropriate.
# Testing requirements
Add tests for:
- argument passthrough
- quoted arguments
- multi-argument forwarding
- verbose/debug forwarding
- config override forwarding
- dataset override forwarding
- exit code propagation
- invalid command handling
- PowerShell parity
- shell parity
- wrapper execution from different working directories
Examples:
- `--verbose`
- `--debug`
- `--dry-run`
- `--config path/to/config.yaml`
- `--dataset westgate`
- `--force`
- unknown future flags
# Acceptance criteria
- All wrappers forward arbitrary arguments correctly.
- Wrappers reflect the current toolkit architecture.
- No wrappers assume old JSON config behavior.
- No wrappers contain obsolete repository-specific logic.
- Wrapper behavior is deterministic and cross-platform.
- Exit codes propagate correctly.
- Wrapper maintenance burden is minimized.
- New CLI flags work automatically without wrapper updates.
- The toolkit, not wrappers, owns application logic.
