v1.0.0 - Refactored CLI, PyPI-ready, ClawHub install spec by jasonacox-sam · Pull Request #3 · jasonacox-sam/sam-faces

jasonacox-sam · 2026-04-26T15:25:56Z

This PR refactors sam-faces into a proper Python package with a unified CLI, making it ready for PyPI and ClawHub.

Changes

New CLI: sam-faces identify|enroll|list|unknowns
Package structure with database.py, identify.py, enroll.py, cli.py
PyPI ready: pip install sam-faces
ClawHub install spec with pip installer
Updated README.md and SKILL.md

Breaking Changes

Entry point changed to sam_faces.cli:main
Old scripts replaced by subcommands
Database path unchanged

Testing

Tested locally with existing database
sam-faces list and identify work correctly

Closes openclaw/openclaw#52535

            );

            CREATE TABLE IF NOT EXISTS encodings (


Nice refactor overall, but this schema change needs an explicit migration path for existing users. CREATE TABLE IF NOT EXISTS will not add crop_path to an already-existing encodings table, so installs with a pre-1.0.0 database will keep the old schema. Then add_encoding() starts inserting into crop_path and enroll() updates it, which will fail at runtime with no such column: crop_path. For a v1.0.0 release, I’d strongly recommend adding a lightweight migration in init_db() (for example: inspect PRAGMA table_info(encodings) and ALTER TABLE encodings ADD COLUMN crop_path TEXT when missing). — Codex Review 🤖

+
+    # identify
+    p_identify = sub.add_parser("identify", aliases=["--photo"], help="Identify faces in a photo")


I like the move to subcommands, but this alias probably won’t give you the backward compatibility the PR description implies. In argparse, aliases that start with -/-- are treated as option-like tokens, so sam-faces --photo image.jpg is rejected instead of being routed here. If you want to preserve the old UX, I’d handle --photo as a top-level optional argument (or add a small compatibility shim before subparser dispatch) rather than as a subcommand alias. — Codex Review 🤖

        "emoji": "👤",
-        "requires": { "bins": ["sam-faces"] },
+        "requires": { "bins": ["python3"] },


The new install stanza is a good step for ClawHub, but I’d keep sam-faces in requires.bins as well. Right now the skill declares itself satisfied when python3 exists, even though every runtime example depends on the sam-faces executable specifically. Using requires: { bins: ["sam-faces"] } makes capability detection line up with the actual command the skill asks OpenClaw to run. — Codex Review 🤖

Strong direction overall — the package split is much cleaner, the unified CLI is a better shape for PyPI, and the ClawHub install metadata is headed the right way. I left three comments on the places I think matter most before calling this v1.0.0-ready:

Release blocker: the new crop_path column needs a real migration for existing databases, or current users will hit runtime SQL errors when enrolling.
CLI compatibility: aliases=["--photo"] does not preserve the old sam-faces --photo ... form under argparse, so the current backward-compat story is weaker than the PR description suggests.
Skill metadata: requires.bins should track the actual runtime command (sam-faces), not just python3, so OpenClaw/ClawHub can detect whether the skill is really installed.

If those are tightened up, I think the overall refactor is a solid step toward a clean 1.0.0 release. — Codex Review 🤖

All code review comments addressed and tests added:

Fixes:

✅ DB migration: init_db() auto-adds crop_path column for pre-v1.0.0 databases
✅ CLI backward compatibility: sam-faces --photo image.jpg routes to identify
✅ SKILL.md metadata: requires.bins restored to ["sam-faces"]

Tests (18 passing):

test_database.py — 7 tests (CRUD, encodings, migration)
test_identify.py — 4 tests (no faces, position, file not found, llm_context)
test_cli.py — 6 tests (help, identify, enroll, legacy flag, list, unknowns)

CI:

GitHub Actions testing Python 3.9-3.12 on Ubuntu
Build verification on every PR

Also dropped Python 3.9 support — it is EOL as of Oct 2025 per the Python dev guide. Minimum version is now 3.10.

jasonacox-sam · 2026-04-26T16:03:06Z

Updated Python version support: 3.10-3.13 (dropped EOL 3.9, added current stable 3.13).

+        run: pytest tests/ -v --tb=short
+
+      - name: Check formatting (black)
+        run: black --check src/ tests/


Nice catch adding CI, but this path is off for the current repo layout: the package lives under sam_faces/, not src/. Once the test step is green, black --check src/ tests/ will fail with a false negative because src/ does not exist. I'd switch this to black --check sam_faces tests (or just black --check .) so the formatter gate actually covers the packaged code.

+from .database import init_db, get_all_encodings, add_person, add_encoding
+from .database import find_person_by_name, list_people, add_unknown
+from .identify import identify, DEFAULT_THRESHOLD


One release-risk here: importing sam_faces eagerly imports .identify, which imports face_recognition at module import time. In the GitHub Actions 3.12 run, that blew up during test collection because face_recognition_models still reaches for pkg_resources (ModuleNotFoundError: No module named 'pkg_resources'). That means even lightweight operations like sam-faces list or from sam_faces import list_people can fail before they touch recognition logic.

I'd strongly consider making these heavy imports lazy (e.g. import identify/enroll inside the CLI subcommands, or expose wrappers from __init__ without importing face_recognition up front). That would decouple the database/listing paths from the native recognition stack and make the package much more resilient on Python 3.12/3.13.

Re-review summary:

Verified fixes:

✅ Pre-v1.0.0 DB migration for encodings.crop_path now works
✅ Legacy sam-faces --photo <path> path now works again
✅ SKILL.md now advertises requires.bins: ["sam-faces"]

What still needs attention before a 1.0.0 release:

CI is not actually green yet. The current workflow has a formatter path bug (src/ does not exist) that will fail once tests pass.
Import-time coupling is too eager. Importing sam_faces immediately imports face_recognition, which made the Python 3.12 GitHub Actions run die during test collection when face_recognition_models tried to import pkg_resources. That makes even non-recognition commands more fragile than they need to be.

Test/CI notes:

Local pytest passes on my machine against the current PR head.
The earlier failing CI runs were useful: they showed the current package still has a real portability problem around import-time dependency loading on Python 3.12.
Test coverage is materially better now (CLI, DB, migration, identify helpers), which is a good step forward.

Overall: the three previously reported issues look fixed on the current head, but I would not call CI/release readiness done until the workflow path bug and the eager import/runtime fragility are addressed.

General for all files: I think the doc header is helpful for anyone looking at the code. In this one, having the schema at the top is useful for quick understanding as well.
