Code Stats

aiskillstore/code-stats

Analyze codebase with tokei (fast line counts by language) and difft (semantic AST-aware diffs). Get quick project overview without manual counting. Triggers on: how big is codebase, count lines of code, what languages, show semantic diff, compare files, code statistics.

Code Statistics

Quickly analyze codebase size, composition, and changes.

tokei - Line Counts

# Count all code
tokei

# Compact output sorted by code
tokei --compact --sort code

# Specific languages
tokei --type=TypeScript,JavaScript

# Exclude directories
tokei --exclude node_modules --exclude dist

# JSON output for scripting
tokei --output json | jq '.Total.code'

Sample Output

difft - Semantic Diffs

# Compare files
difft old.ts new.ts

# Inline mode
difft --display=inline old.ts new.ts

# With git
GIT_EXTERNAL_DIFF=difft git diff
GIT_EXTERNAL_DIFF=difft git show HEAD~1

Why Semantic?

| Traditional diff | difft |

|-----------------|-------|

| Line-by-line | AST-aware |

| Shows moved as delete+add | Recognizes moves |

| Whitespace sensitive | Ignores formatting |

Quick Reference

| Task | Command |

|------|---------|

| Count all code | tokei |

| Compact output | tokei --compact |

| Sort by code | tokei --sort code |

| TypeScript only | tokei -t TypeScript |

| JSON output | tokei --output json |

| Exclude dir | tokei --exclude node_modules |

| Semantic diff | difft file1 file2 |

| Git diff | GIT_EXTERNAL_DIFF=difft git diff |

When to Use

  • Getting quick codebase overview
  • Comparing code changes semantically
  • Understanding project composition
  • Reviewing refactoring impact
  • Tracking codebase growth

How to use it

Copy the folder

Take aiskillstore/code-stats from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference brew, cargo, go. Without those the skill loads but fails at the first command.
