servicenow-atlas: Skill for Claude Code

When to use

• Adding/removing/renaming a file in the project — is the tree diagram still right?
• Changing a CLI flag, config key, or command signature — are all code blocks updated?
• Bumping a version — does the "current version" note need updating?
• Changing architecture (e.g., swapping build strategy) — are all prose claims still true?
• Adding or removing a section — does the table of contents still match?
• Editing the README at all — always check for stale claims while you're there.

Rot patterns to catch

1. Stale prose claims

Assertions about how the system works that were true at vN but wrong at vN+1. Search the README for every occurrence of the changed concept.

Common culprits:

• Build/deploy strategy — "CI does X" after CI was rewritten
• Default behavior — "the server auto-selects Y" after the default was changed to Z
• Dependency claims — "requires pandas" after it was removed
• Status labels — [planned] on something now implemented, or vice versa

2. Broken section references

Internal links [§5.3](#53-smoke-test-ci) break when section headings change. After editing any heading, grep the README for the old anchor text and update every cross-reference.

3. Version note rot

Many READMEs have a "current version" callout box. This should be updated on every release — at minimum the version number and a one-line summary of what changed. If you bump the version in pyproject.toml but not the README note, it's wrong.

4. ASCII tree diagram drift

Directory structure diagrams (├── foo.py description) rot silently because they look right at a glance. After any file add/remove/rename:

• Verify every file in the diagram still exists

• Verify every file in the project that matters is listed

• Align descriptions vertically — pick a column position for descriptions and pad every filename to it. Use monospace alignment: the longest filename in the diagram sets the column for its nesting level.

  Bad (misaligned):

  ├── foo.py        Does X
  ├── bar.py                  Does Y
  ├── baz-long-name.py   Does Z
