How Claude Code mods work

  • A mod is a plugin with a JavaScript or TypeScript module that runs inside Claude Code (version 2.1.287 or later). It can draw panes beside the transcript, a band above the prompt, buttons and toasts, restyle the spinner and tool rows, and watch or rewrite tool calls and prompts.
  • It installs like any plugin: add its marketplace with /plugin marketplace add owner/repo, then /plugin install name@marketplace.
  • Check what a mod can reach before installing: it runs with your permissions. Reach goes from drawing only, to reading files, to writing files or running processes, to the network. Run claude plugin validate on a clone to list its hooks and calls without running it.
  • Turn one off from the Installed tab in /plugin, or start Claude Code with --safe-mode to skip every customization for a session.

slicer-handoff

joeldg/claude-mods

Hands models to the right slicer: full-spectrum (Snapmaker U1) files Claude tries to open in Bambu Studio go to Snapmaker Orca instead, and previous slicer windows are gently quit first so they don't pile up. /slice opens a file the same way.

Memory & instructions mods

handoff

1

LupusMalusDeviant/mod-box

/handoff writes a handoff note to .claude/handoff.local.md; a new session offers to continue from it.

flaky-memory

12

KilimcininKorOglu/claude-code-mods

Remembers which tests failed on which code, and tells the model when a failing test has both passed and failed on the same code, so it runs the test again instead of changing code.

memo-prop-note

1

MatheusChiodi/cockpit

Tells Claude when an edit passes an inline object, array or function to a component wrapped in memo, which defeats the memo

Memory & instructions mods

auto-model

aecheman27-gif/claude-mods

Picks the model per prompt with local rules: quick questions to Haiku, writing and explaining to Sonnet, building and fixing to Opus. The whole conversation always goes along; it switches only when the other model's prompt-cache re-read costs little.

config-parse

12

KilimcininKorOglu/claude-code-mods

Parses each JSON, YAML, TOML or .env file an Edit or Write touches, notes a parse error at once instead of at the next build, and says so again when a later edit fixes it.
