context-watch
コンテキスト使用量、コスト、現在のレート制限をプロンプト上部の1行ゲージで示し、60/80/90%でトーストを表示し、コンパクション後も指示と編集ファイルを保持して、/ctxコンテキスト内訳ペインを追加するClaude Codeのfunction-hook modです。
この mod について
context-watchはClaude Code用のfunction-hook modで、narrowstacks/claude-code-modsマーケットプレイスから配布されています(各フォルダーが1つのプラグインです)。プロンプト上部にコンテキスト使用量、コスト、現在のレート制限を示す1行ゲージを描画し、60%、80%、90%でトーストを表示し、コンパクションをまたいで固定指示と編集ファイルを保持し、/ctxコマンドで詳細なコンテキスト内訳ペインを開きます。claude plugin marketplace add narrowstacks/claude-code-modsに続けてclaude plugin install context-watch@claude-code-modsでインストールするか、--plugin-dirでチェックアウトから読み込めます。claude plugin validateとclaude plugin testで検証とテストができ、Claude Codeが.claude-plugin/types/を書き込んだ後はTypeScriptのコンパイルも動作します。

原文 / README
claude-code-mods
Function-hook mods for Claude Code. Each folder is one plugin.
| Mod | What it does |
| --- | --- |
| context-watch | One-line gauge above the prompt for context fill, cost and hot rate limits; toasts at 60/80/90%; compaction keeps your instructions and edited files; /ctx opens a context breakdown pane |
| live-spinner | Spinner shows what is running: the Bash description or a trimmed command, the ssh host, file being read or edited, search, subagent, MCP tool; a tool's own elapsed time after 15s; "Waiting for signing approval" when a signed git commit or tag sits quiet |
| pr-watch | Tracks PRs from gh pr / gt submit / git push output, shows checks above the prompt, toasts on green/red/merged, blocks foreground CI polling loops; /prs |
| house-style | No em dashes: system prompt rule, reminder to the model after a write that adds one, toast when a reply uses one |
| handoff | /handoff [focus] writes a state note from the conversation and clears; the next prompt carries it. /handoff save, show, drop |
| agent-jobs | /jobs opens a pane of running subagents and background shells with elapsed time and a Stop button; toasts when background work finishes |
| zsh-safe | Quotes glob flags zsh would expand (--include=*.ts, find -name *.ts) and keeps a grep that finds nothing from failing a cd ... && grep chain |
| pm-guard | Blocks npm/npx/yarn where the lockfile says bun or pnpm, and steers to bun where there is no lockfile |
| remote-guard | Asks before a destructive command (restart, rm, kill, reboot, pct/qm stop, zfs destroy) runs over ssh |
| xcode-status | Only in a folder with an .xcodeproj/.xcworkspace: one line with the last build or test result (flags runs that executed 0 tests) and the booted simulator; blocks a second xcodebuild while one is running; re-checks on /cd and keeps each project's last result |
| agent-models | Pins the model each subagent type runs on (Explore, general-purpose, Plan, any other, plus custom type=model pairs), set in /config or with /agent-models <type> <model>; a model the caller names wins unless "Override explicit models" is on |
| worktrees | /worktrees pane: each git worktree with branch, uncommitted changes, ahead/behind and PR state; Remove (after asking) on clean worktrees whose PR is merged or closed, plus "Remove N merged" to clear every merged one at once |
| pr-rules | Blocks gh pr create / gt submit when the repo keeps an [Unreleased] changelog and the branch adds no entry (skip with --label no-changelog); where the repo's CLAUDE.md says to label every PR (or requireLabels is on), blocks a PR with no --label and lists the repo's labels. Repos with neither are untouched; /pr-rules on|off|auto overrides per repo (kept across sessions) |
Install
claude plugin marketplace add narrowstacks/claude-code-mods
claude plugin install context-watch@claude-code-mods
Or load from a checkout without installing:
claude --plugin-dir ./context-watch --plugin-dir ./live-spinner
Check
claude plugin validate ./context-watch
claude plugin test ./context-watch
tsc -p ./context-watch works once Claude Code has loaded the mod and written .claude-plugin/types/.
