README

claude-code-mods

Mods for Claude Code that add a band above the prompt, a side pane or a slash command. Each is its own plugin, so you can install only the ones you want.

The mods

Plugin	Band	What it does	Command
`band-rule`	line	Draws a dim line above the bands to separate them from Claude's output. List it before the other mods (see below).	none
`cache-clock`	CACHE	Shows whether the prompt cache is still warm, the time left, % reused and the cold-rewrite cost, with a Compact button. Toasts shortly before the cache goes cold.	`/cache-clock on \	off \	status`
`usage-gauge`	USAGE	Plan usage windows (5h, week, others) with reset times, the session cost and a pace warning. Toasts at 75% and 90%.	`/usage-gauge` (opens a pane), `on \	off \	warn <a> <b> \	status`
`usage-limits`	footer	Session (5h) and week (7d) rate-limit bars in the prompt footer.	none
`auto-handoff`	CONTEXT	Watches how full the chat is and saves a `HANDOFF.md` when it reaches a threshold, then offers to clear and resume.	`/auto-handoff on \	off \	now \	resume \	threshold <n> \	mode auto\	ask \	hide \	show \	status`
`agent-watch`	AGENTS	Shows the main chat and helper agents with their models and tasks, plus the skills that ran this turn. Opens an Agents pane.	`/agent-watch` (opens the Agents pane), `on \	off \	clear \	help`

Bands stack in the order their plugins appear in enabledPlugins in ~/.claude/settings.json, first on top. To reorder, move the lines and run /reload-plugins; claude plugin install adds new entries at the end. band-rule draws its line above the whole stack only when it is listed first. The author's order, top to bottom: band-rule, agent-watch, auto-handoff, cache-clock, usage-gauge, usage-limits. The last one draws in the footer, so its place doesn't matter. The Band column is the title each mod shows in its band.

Each band is one row. In a narrow terminal the end of the row is cut off with … instead of wrapping.

usage-gauge and usage-limits both show plan usage, so enable only one.

In auto mode, auto-handoff sends the handoff prompt as soon as the threshold is crossed, even while Claude is mid-task. The default ask mode only offers the button.

cache-clock has a cacheMinutes option (5 or 60, default 60). Other settings are set through each mod's commands and persist between sessions.

Install

Install a mod from the marketplace:

/plugin install cache-clock --marketplace Abdallah-Abdelazim/claude-code-mods

Run it once per mod, changing the plugin name. From a local clone, use --marketplace ~/path/to/claude-code-mods instead.

To try one without installing: claude --plugin-dir plugins/<name>.

Requirements

These mods use Claude Code's function-hook plugin API, which is in early access; they were written against Claude Code 2.1.303. Where an organization manages Claude Code, plugins you install don't run the session.compact, skill.prompt and prompt.compose hooks.

Develop

Each folder under plugins/ is a standalone mod: .claude-plugin/plugin.json, hooks/, tsconfig.json, a *.test.ts and, for a mod that keeps state, types/index.d.ts. See CLAUDE.md for the conventions and the release steps.

claude plugin validate plugins/<name>
claude plugin test plugins/<name>

The engine writes .claude-plugin/types/ inside a mod when it loads it; the folder is git-ignored.
