Repo Structure Reviewer

Overview

Create a repo anatomy review and an optimized structure plan, then apply approved changes safely with a rollback plan. Default behavior is dry-run, with per-change approvals before any filesystem modifications.

Quick Start

python3 skills/repo-structure-reviewer/scripts/repo_structure_review.py --root .

Apply mode (still per-change approval):

python3 skills/repo-structure-reviewer/scripts/repo_structure_review.py --root . --apply

Scope and safety controls:

python3 skills/repo-structure-reviewer/scripts/repo_structure_review.py --root . --scope top-level-only --max-changes 25

Full scan with file cap:

python3 skills/repo-structure-reviewer/scripts/repo_structure_review.py --root . --scope full-scan --max-files 20000

Workflow

Phase A: Review + Plan

1. Scan the repo structure and detect languages/frameworks/build systems.
2. Produce a "Repo Anatomy Review" report:
   • top-level tree summary + key subtrees
   • detected languages/frameworks/build systems
   • pain points and smells
   • archive candidates
   • stale/outdated/delete candidates
3. Produce an "Optimization Plan":
   • target structure outline
   • ordered list of proposed changes
   • per-change rationale, risk, and reversibility notes

Phase B: Approval + Apply

If --apply is provided, start an interactive approval loop:

• Prompt one change at a time (or batched when explicitly supported) with:
  • Change ID
  • Operation type (MOVE/RENAME/CREATE)
  • Before/After paths
  • Rationale
  • Risk level
  • Show details / show diff options
• Print the full list of proposed files/changes for the selected phase before prompting for approvals.
• Require explicit approval for each change.
• Default to skip for delete candidates.
• Stop on error and report the last successful step and rollback guidance.

Hard Safety Requirements

• Default is DRY RUN. No changes without explicit user approval.
• Prefer git mv when git is present and the file is tracked.
• Never delete by default.
  • Deletion proposals require explicit approval.
  • Default action is soft-delete into .repo_reorg_backup/deletions/<timestamp>/....
  • Permanent delete requires explicit per-item approval.
• Generate a rollback plan for every applied change.
• Never edit lockfiles unless explicitly approved.
• If any step fails, stop and report how to roll back.

Archive + Stale/Delete Review

The Repo Anatomy Review must include two additional sections:

Archive Candidates (safe to keep, not active)

Flag items that likely belong in an archive area. For each item list:

• path
• why flagged (signals: last modified time, naming patterns, lack of references, superseded by newer file/folder)
• confidence (low/med/high)
• suggested destination (e.g., archive/, docs/archive/, .archive/)
• safe handling note: archive = move, not delete

Stale / Outdated / Delete Candidates (needs review)

Flag items that might be removable or require updating. For each item list:

• path
• why flagged
• evidence (last modified, reference scan results, git tracked status, file size)
• recommendation: archive vs update vs delete
• confidence (low/med/high)
• risk notes

Heuristics must be conservative and always label results as candidates.

Outputs / Artifacts

• repo_anatomy_review.md
• repo_reorg_plan.json
• repo_reorg_actions_log.md
• rollback_plan.json
• ARCHIVE_INDEX.md (when archive moves are approved)

Implementation Layout

• scripts/repo_structure_review.py - CLI entrypoint
• scripts/scanner.py - repo scanning and metadata extraction
• scripts/planner.py - plan generation and candidate detection
• scripts/approvals.py - interactive approval loop
• scripts/applier.py - safe apply + reference updates
• scripts/reporting.py - report + artifact writers
• scripts/models.py - dataclasses shared across modules

Tests

Use pytest to validate:

• dry-run makes zero modifications
• apply requires explicit approval
• rollback artifact is generated
• git move path uses git mv when git is present (with fallback)
• archive moves create/update ARCHIVE_INDEX.md
• delete candidates are not removed without explicit approval

Run:

python3 -m pytest skills/repo-structure-reviewer/tests
