Grade

Score: 92/100

Justification: The codebase is in excellent shape. All automated tooling passes cleanly: ruff check (0 violations), ruff format --check (70/70 files formatted), ty check (0 diagnostics), mypy --strict (0 issues across 70 files), and vulture --min-confidence 80 (0 dead-code findings). The unused_all_exports_scanner reports 0 unused exports. No relative imports, no module-level constant naming violations, no abbreviated filenames, and docstrings with Args/Returns sections consistently provide semantic context beyond what the type annotations express (rule #14 compliant). The single deduction is one acronym-casing violation (ADRCli → should be ADRCLI) flagged by the deterministic acronym_casing_scanner (rule #3, enabled). This is a low-impact naming issue costing 8 points. No critical, high, or auto-fixable issues were found.

Tool Results

Ruff

Check	Status	Details
ruff check	PASS	All checks passed! (0 violations across 70 files)
ruff format --check	PASS	70 files already formatted

Config: line_length=100, target=py312, select=[E,W,F,I,B,C4,D,UP,T20,SIM], ignore=[B008,T201,D104,D107,D203,D213].

Type Checker (ty + mypy)

Check	Status	Details
ty check	PASS	All checks passed!
mypy --strict	PASS	Success: no issues found in 70 source files

Both type checkers are configured (ty python 3.12, mypy strict python 3.12) and both run per the skill's "when both are available, both run" directive. No type errors and no missing type annotations on public APIs (rule #19).

Vulture (dead code)

Check	Status	Details
Dead code	PASS	0 findings at --min-confidence 80

Scanners

Scanner	Status	Details
acronym_casing_scanner.py	FAIL	1 violation: ADRCli — word Cli should be CLI
one_class_per_file_scanner.py	PASS (1-class) / FALSE POSITIVES (filename)	No files with 2+ classes. 10 filename-vs-class "mismatches" are false positives: the scanner does not handle the documented convention that acronyms stay uppercase in the class name but lowercase in the filename (rule #9). All 10 are ADR*/API*/PHP* classes whose filenames correctly lowercase the acronym.
unused_all_exports_scanner.py	PASS	6 files with __all__, 13 entries, 0 unused
naming_conventions_scanner.py	PASS (source side)	Source file/class-name matching overlaps with one_class_per_file_scanner; same acronym false positives. Test-mirror check could not run cleanly (test layout is flat under tests/, not nested under a package dir) — out of scope for this skill.

Auto-Fixable (Informational)

These issues do not count toward the grade. They can be fixed automatically with ruff check --fix, ruff format, or ty check --fix.

No auto-fixable issues found. ruff check reports no fixable diagnostics and ruff format --check reports no files needing reformatting.

Findings

Critical

No critical findings.

High

No high findings.

Medium

#	File	Symbol	Rule ID	Issue	Suggested Fix
1	src/zolletta_metaskill/adr/adr_cli.py:21	ADRCli	#3 (acronym casing)	Class name ADRCli keeps the CLI acronym in mixed case (Cli). The configured acronym list includes CLI; the convention requires acronyms to stay fully uppercase in PascalCase class names.	Rename the class to ADRCLI. The filename adr_cli.py already follows the "acronym lowercase in filename" convention and will then match the renamed class. Update the two internal references in adr_cli.py (ADRCli.build_parser, ADRCli.run, ADRCli.missing_docs_error, ADRCli.format_report).

Low

No low findings. Vulture reported no dead code and the __all__ scanner reported no unused exports.

Manual Review Checks

Rule	Area	Status	Notes
#1	Naming — descriptive snake_case filenames	PASS	All 44 non-__init__ filenames are descriptive snake_case; no abbreviations (adr, api, php are domain acronyms, not lazy abbreviations).
#2	Naming — PascalCase class names	PASS	All 49 classes use PascalCase.
#3	Naming — acronyms uppercase	FAIL	ADRCli flagged by scanner (see finding #1). All other ADR*/API*/PHP* classes correctly keep acronyms uppercase.
#4	Naming — snake_case functions/variables	PASS	No violations detected by manual scan or ruff.
#5	Naming — SCREAMING_SNAKE_CASE constants	PASS	No module-level PascalCase value constants found; enum/class aliases use the documented exception correctly.
#6	Imports — grouped order	PASS	Enforced by ruff I rule; 0 violations.
#7	Imports — absolute only	PASS	No relative imports found (grep for from \.\. returned nothing).
#8	Structure — one class per file	PASS	Scanner confirms no file has 2+ classes.
#9	Structure — filename matches class	PASS	All matches follow the "acronym uppercase in class, lowercase in filename" convention; scanner false positives suppressed per rule #9 documentation.
#12	Docstrings — public APIs	PASS	ruff D100–D106 enabled; 0 violations. Public classes/methods/functions all have docstrings.
#13	Docstrings — private exempt	PASS	Private (_-prefixed) functions correctly lack docstrings where implementation details.
#14	Docstrings — no type repetition	PASS	Args/Returns sections reviewed provide semantic context beyond type annotations (e.g. "Path to a .py source file", "e.g. \"python\""). No bare type restatements found.
#17	Docstrings — test functions exempt	N/A	Tests out of scope (src/ only).
#18	Docstrings — skip obvious one-liners	PASS	No noise docstrings on self-documenting one-liners found.
#19	Types — public API hints	PASS	mypy --strict and ty check both pass with 0 issues.
#20	Formatting — line length	PASS	ruff format --check passes; line length 100 enforced.
#22	Dead code — vulture + __all__	PASS	Vulture 0 findings at confidence 80; __all__ scanner 0 unused exports.

Architectural Directive Alignment

Directive	Alignment	Notes
ADR-0004 — Python stdlib only for scanners	Aligned	Scanners use only stdlib (ast, argparse, pathlib, json); no third-party imports in scanner modules.
ADR-0007 — Language-neutral engine protocol	Aligned	LanguageEngine protocol + ModuleInfo data model present; PythonEngine/PHPEngine implementations follow the protocol. (PHPEngine class name correctly keeps PHP uppercase.)
ADR-0009 — Inline shell replaced with Python scripts	Aligned	Setup detectors are standalone Python scripts under src/zolletta_metaskill/setup/, all typed and documented.

No architectural directive violations observed.

Recommendations

1. Rename ADRCli to ADRCLI in src/zolletta_metaskill/adr/adr_cli.py to satisfy the acronym-casing convention (rule #3). This is the only outstanding style issue; resolving it would bring the codebase to a clean pass on all enabled rules.
