Claude Code mod

jev-compact

Context compaction that prunes instead of summarising: rules drop exploration output and hook noise locally, Jev ranks the rest against a budget, a note says what was removed, and removed outputs are archived for the brain. Falls back to the built-in summary when it cannot do better.

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.

More context & usage mods

jev

gecm0/jev-mod

Adds $.jev: typed Choice, Score and Noul judgments from TypeSafe's Jev, with a timeout and validated answers, for other mods to call.

Context & usage mods/plugin install

jev-compact-trigger

HAR5HA-7663/jev-compact

Companion to jev-compact: watches context use after every turn and starts a compaction at the configured percentage. Separate plugin on purpose — the engine skips a plugin's own session.compact hook when that plugin raises the compaction, so the trigger must come from outside jev-compact for the pruning to run.

JC HUD — mod Claude Code : barre d'instruments Jasmine Conseil (contexte, forfait, modèle, horloges)

Context & usage mods

jev-skill-suggestion

AnatoliyShk/bulgolingo

Keeps the skill listing out of the context window and lets TypeSafe's Jev, a System One decision model, pick at most one skill per prompt from the skills' descriptions, the way TypeSafe's skill-suggestion cookbook does: one request ranks every skill and asks whether the prompt needs a skill at all, a second re-reads the top three with their SKILL.md and can reject them all. The winner's SKILL.md is attached to the prompt, so the skills can be hidden from the model altogether (/jev-skill-suggestion:setup makes them user-invocable-only and /context counts them at 0). Falls back to the engine's built-in classifier when no key is set.

Context & usage mods

integral

serg-yalosovetsky/integral

One HUD above the prompt: context bar with compact/checkpoint, plan limits, MCP health, plan progress. Replaces context-bar-compact and mcp-doctor.

Context & usage mods/plugin install

k9s

holdennguyen/claude-code-setup

A live, interactive k9s terminal in a pane (k9s runs under a private tmux server, so kube auth and context come from the shell that launched Claude Code), plus two tools so the model can read the k9s screen and send it keys. While k9s runs, Bash calls that invoke kubectl are refused and the model is pointed at those tools; kubectl works as usual otherwise. One server per Claude Code process, a watchdog and a start-up sweep keep orphans from surviving, and an idle stop keeps k9s from polling the cluster unseen.
