About this mod

English | 简体中文

glance

A HUD under your Claude Code prompt, written as a Claude Code mod. One look tells you the model, the branch, what the session has cost, how full the context is, where your 5-hour and 7-day limits stand, and what Claude is running right now.

Requires Claude Code 2.1.289 or newer. Mods are an early-access API that may change between releases. If glance stops drawing after an update, please open an issue.

Install

In Claude Code:

/plugin marketplace add VibeMage/claude-mod-glance
/plugin install glance@claude-mod-glance

Or from a shell:

claude plugin marketplace add VibeMage/claude-mod-glance
claude plugin install glance@claude-mod-glance

Start a new session (or run /reload-plugins) and glance appears under the prompt.

glance runs alongside a statusLine such as claude-hud. If you are switching from one, remove statusLine from ~/.claude/settings.json so you do not see the same figures twice.

What it shows

| Row | Contents | Source | | --- | --- | --- | | Header | Model (claude-opus-5-5 → Opus 5.5), git branch, ahead ↑ / behind ↓, changed files ●, session cost, session duration | $.session.model(), git status --porcelain=v2, $.session.usage() | | Bars | Context fill with tokens used, then each rate-limit window (5h, 7d) with the time until it resets. Each bar has its own colour and turns red at the warning threshold | $.session.usage(), refreshed on session.measure | | Tools | Tools running now (◐) and the session's most-used tools | tool.call | | Skills and MCP | Skills loaded this session, latest first (✦); MCP calls running now (◐) and calls per server (⧉) | skill.prompt, tool.call | | Agents | Subagents running (⚙) and how many the session has started | tool.call on Agent | | Todos | Progress and the item in progress, from TodoWrite or the Task tools | tool.call |

When glance loads (a new session, --resume, or installing it mid-session), it reads the transcript, so the tools, MCP servers, skills and todos used before it loaded are counted too.

The cost is what /cost reports: an estimate at API list prices. On a Pro or Max subscription it is not what you are billed.

What glance runs and reads

glance is a single TypeScript module (hooks/register.tsx) that Claude Code runs in its mod sandbox. It has no dependencies, downloads nothing and opens no network connections. Everything it reads stays on your machine.

• Runs one program, git, as git status --porcelain=v2 --branch in the session's working directory, when the session starts, after each turn and every 30 seconds, for the branch, ahead/behind and changed-file count.
• Reads, through the mod API: the session's model, context fill, rate-limit windows and cost ($.session.usage()), the session's transcript ($.session.messages(), only the names and inputs of tool calls, to count tools, MCP servers, skills and todos), and your Claude Code theme setting ($.settings.read(), to pick light or dark colours).
• Observes tool calls (tool.call) and skill loads (skill.prompt) as they happen, to note the tool's name and a short label and the skill's name. Every call and every skill prompt passes through unchanged; glance never blocks, rewrites or adds to them.
• Keeps its figures in the session's mod state only. It writes no files and stores nothing across sessions.
• Sends nothing anywhere: it makes no network calls and passes no data to git, whose only input is the fixed argument list above.

Configure

Run /plugin configure glance@claude-mod-glance, or open /config and find the glance rows. Changes apply immediately.

| Option | Default | What it does | | --- | --- | --- | | palette | auto | auto: Cupertino (iOS system colours), light or dark following your Claude Code theme. catppuccin: Latte or Mocha, chosen the same way. mocha, macchiato, frappe, latte: always that Catppuccin flavor | | barWidth | 10 | Cells in each bar (4–30) | | warnAt | 85 | Percentage at which a bar and its figure turn red | | showGit | true | Branch, ahead/behind, changed files | | showCost | true | Session cost | | showDuration | true | Session duration | | showTools | true | Tools row | | showSkills | true | Skills and MCP row | | showAgents | true | Agents row | | showTodos | true | Todos row | | keepHint | true | Keep Claude Code's own hint line (? for shortcuts, esc to interrupt) under the HUD |

Known limitations

• glance draws in place of the hint line under the prompt and redraws that hint as plain dim text, so the hint's own colours (for example the auto mode on pill) are lost. Turn the line off with keepHint: false.
• A skill you invoke as /name is not in the transcript's tool calls, so it is only counted if glance was already loaded when you ran it.
• Rate-limit bars appear only on a subscription, after the first response of the session reports them.

Develop

git clone https://github.com/VibeMage/claude-mod-glance
cd claude-mod-glance
claude --plugin-dir .          # load it for one session; saving a file reloads it
claude plugin validate .       # what the engine would refuse
claude plugin test .           # tests/*.test.ts against the engine

The engine writes the API's types to .claude-plugin/types/ the first time it loads the mod, along with a tsconfig.json, so tsc -p . type-checks it. Both are build-specific and git-ignored.
