check-directory-structure

name	check-directory-structure
description	Inspect repository layout with tree and find, compare to AGENTS.md conventions, and fix misplaced or overly flat generated files. Use when auditing folder structure, after scaffolding or bulk file generation, when output looks flat, or when asked where code/tests/docs should live. Supports inspecting the repository root or a specified subdirectory.
compatibility	Unix-like shell. POSIX find required; optional tree for readability (install via OS package manager if missing). Run from inside the working tree; set TARGET to the directory to inspect (default `.` for the current directory, often the repo root after `cd`).

Check directory structure

Purpose

Ground work in the actual on-disk layout and catch flat or misplaced output (for example many new files at the repository root) before finishing a task.

When to use

• After scaffolding, renaming the package, or generating several new files
• When imports or paths feel wrong compared to where files really live
• When the user asks where code, tests, or scripts should live
• When output looks like a flat dump instead of nested package layout

How to run

Read Architecture and testing layout in AGENTS.md. This repository uses package sqlfluff_complexity under src/sqlfluff_complexity/ (confirm with pyproject.toml and src/ on disk if unsure).

Target directory: By default, inspect the current directory (after cd to the repository root, that is the whole repo). To inspect only a subtree—for example a package or feature folder—set TARGET to that path (repo-relative or absolute). Examples: TARGET=. (same as root after cd to repo root), TARGET=src/sqlfluff_complexity, TARGET=dev. Use the same TARGET in every command below.

# From repository root; inspect whole repo
TARGET=.

# Or inspect only a subtree (repo-relative or absolute path)
TARGET=src/sqlfluff_complexity

1. Snapshot layout

Optional — readable tree (skip if tree is not installed):

tree -L 3 -a -I '.git|__pycache__|.venv|node_modules|dist|build|.pytest_cache|.ruff_cache' "${TARGET:-.}"

POSIX find — works without tree: run from inside TARGET so skipping .git, .venv, and __pycache__ works for both the repo root and a subdirectory.

# Immediate children of TARGET (plus `.` for the root of the scanned tree)
(cd "${TARGET:-.}" && find . \( -name '.git' -o -name '.venv' -o -name '__pycache__' \) -prune -o -maxdepth 1 -print)

# Sample of files under TARGET (cap output on large trees)
(cd "${TARGET:-.}" && find . \( -name '.git' -o -name '.venv' \) -prune -o \( -type d -name '__pycache__' \) -prune -o -type f -print | head -200)

Optional — depth signal (rough hint for flat vs nested paths under TARGET):

(cd "${TARGET:-.}" && find . -type f -print | awk -F/ '{ print NF-1 }' | sort -n | tail -5)

If TARGET is not the repository root, map what you see back to the full repo layout in AGENTS.md (for example src/sqlfluff_complexity/ vs dev/).

2. Compare to this repository

• Package code lives under src/sqlfluff_complexity/, not loose Python modules at the repository root.
• Tests live under src/sqlfluff_complexity/tests/; files match test_*.py (see AGENTS.md).
• Dev scripts: dev/; CI: .github/workflows/; ADRs: docs/adr/ when used.

For bootstrapping a new project from the Python template (rename package, clean docs), use initialize-project.

3. Fix loop

1. Move misplaced files to match the conventions above.
2. Update imports, packaging paths in pyproject.toml, and references in docs or CI if paths changed.
3. Verify with make lint && make test per AGENTS.md.

Termination

• Layout matches documented conventions, or
• Remaining differences are explicitly accepted with a short rationale, or
• After 2 relocate/fix iterations, stop and list remaining items for the user.
