# Phase 1: Script Skeleton Verification Report

**Phase Goal:** Script can parse git commands from argv and show what would execute
**Verified:** 2026-01-18T00:15:00Z
**Status:** passed
**Re-verification:** No - initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | User can invoke 'gitsl status' and script identifies 'status' as the command | VERIFIED | `python3 gitsl.py status` outputs `[STUB] Would process: git status` |
| 2 | User can invoke 'gitsl commit -m msg' and script identifies 'commit' with args ['-m', 'msg'] | VERIFIED | Debug mode shows `Command: commit` and `Args: ['-m', 'test message']` |
| 3 | User can run with GITSL_DEBUG=1 and see debug output showing what would execute | VERIFIED | `GITSL_DEBUG=1 python3 gitsl.py commit -m "msg"` shows `[DEBUG] Would execute: sl commit -m 'msg'` |
| 4 | Running 'gitsl' with no arguments shows usage message and exits with code 1 | VERIFIED | `python3 gitsl.py` outputs usage and exits 1 |
| 5 | Running 'gitsl --version' shows version and exits with code 0 | VERIFIED | `python3 gitsl.py --version` outputs `gitsl version 0.1.0` and exits 0 |

**Score:** 5/5 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `gitsl.py` | Git-to-Sapling CLI shim entry point | VERIFIED | 125 lines, has all required exports |

**Artifact Verification (3 levels):**

1. **Existence:** gitsl.py exists at `/Users/vmakaev/Non-Work/gitsl/gitsl.py`
2. **Substantive:** 125 lines (min required: 80), no stub patterns blocking functionality
3. **Wired:** N/A for entry point - this is the root of the application

**Exports verified:**
- `main` - entry point function
- `parse_argv` - argument parsing function
- `ParsedCommand` - dataclass for parsed command representation
- `is_debug_mode` - debug mode detection function

### Key Link Verification

| From | To | Via | Status | Details |
|------|-----|-----|--------|---------|
| `gitsl.py` | `sys.argv` | `main()` receives `argv[1:]` | WIRED | Line 93: `argv = sys.argv[1:]` |
| `gitsl.py` | `os.environ` | `is_debug_mode()` checks `GITSL_DEBUG` | WIRED | Line 63: `os.environ.get("GITSL_DEBUG", "")` |

### Requirements Coverage

| Requirement | Status | Details |
|-------------|--------|---------|
| EXEC-01: Script parses argv and extracts git command + arguments | SATISFIED | ParsedCommand extracts command and args correctly |
| EXEC-06: Debug mode shows command that would run without executing | SATISFIED | GITSL_DEBUG=1 shows `[DEBUG] Would execute: sl <command>` |

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| gitsl.py | 72 | "placeholder for Phase 1" comment | Info | Expected - Phase 1 is skeleton only, notes future work |
| gitsl.py | 120 | `[STUB] Would process` output | Info | Expected - Phase 1 explicitly outputs stub message until execution pipeline added in Phase 3 |

**Assessment:** No blocking anti-patterns. The "stub" output and "placeholder" comment are intentional Phase 1 design - the goal is to parse and show what would execute, not to actually execute commands.

### Human Verification Required

None required. All verification was done programmatically with bash commands.

### Summary

Phase 1 goal is fully achieved:

1. **Argument parsing works correctly:** The script correctly identifies the git command and its arguments from argv
2. **Debug mode works:** Setting GITSL_DEBUG=1 shows debug information including the command that would be executed
3. **Edge cases handled:** Empty args returns exit 1 with usage, --version and --help work correctly
4. **Exports available:** All required functions and classes are importable for future phases
5. **Key links wired:** sys.argv and os.environ are correctly integrated

The script skeleton provides the foundation for all subsequent phases. Phase 2 (E2E Test Infrastructure) can proceed to add test harnesses, and Phase 3 (Execution Pipeline) can add actual command execution.
