Works with Claude Code, Cursor, and any MCP-compatible agent. ## About Quick start  ·  How it works  ·  Policy  ·  Ecosystem  ·  FAQ  ·  简体中文 A Claude Code plugin that gives the Claude agent an MCP tool to read its own subscription quota during long tasks, plus a vigilance policy that gracefully wraps up and uses ScheduleWakeup to sleep through the 5-hour reset — so the agent does not hit the rate limit wall mid-work. --- ## ✨ Why this exists Claude Code enforces two rolling quotas: a **5-hour session window** and a **7-day weekly cap**. Hit either of them mid-task and the session stops cold — half-finished refactors, dead conversations, lost flow. Today, the only way to know how much budget Claude has left is for *you* (the human) to ask Claude Code's UI. Claude itself, the agent doing the actual work, has **no idea** how close it is to the wall. `claude-quotas` fixes that asymmetry. It's a Model Context Protocol (MCP) tool the agent uses **vigilantly** during multi-step tasks: take a baseline reading at the start, re-check as utilization grows, and — when crossing per-plan thresholds — gracefully wrap up the current unit, commit a checkpoint, and **`ScheduleWakeup`-sleep through the quota reset** instead of slamming into the wall mid-task. > **TL;DR** — gives Claude the eyes to see its own quota *and* the discipline to ride out the reset, rather than dying in the middle of your refactor. ## 🎯 Features - 🧠 **Self-introspection** — Claude reads its own usage at any point during a task, not just when you ask. - 🛡️ **Vigilant by design** — not "quiet by default", not "noisy by default" — *measured*. Baseline at task start, re-check as the work progresses, act only at threshold zones. - 💤 **Auto-sleep through the wall** — at the per-plan sleep threshold, Claude wraps up the current unit, commits a checkpoint, writes a resume note, and `ScheduleWakeup`s through the quota reset (with relay-sleeps for windows longer than the runtime's 1-hour cap). When you come back, the work is already continuing. - 🔁 **Auto-baseline on resume** — ships a `SessionStart` hook (matcher: `resume`) that re-runs `check_quota` the moment a session resumes (e.g. after a `ScheduleWakeup` wake-up), injecting the fresh utilization summary into the conversation as additional context. Claude sees its post-reset quota state in the very first frame, without depending on the LLM remembering to call the tool. - 🤖 **`/loop`-aware** — knows that autonomous runs don't have a human at the keyboard, so it gets stricter (extra 1% safety margin) when it detects a loop context. - 📊 **Every quota window** — 5-hour session, 7-day weekly, Opus weekly, Sonnet weekly, and pay-as-you-go extra usage. - 🚦 **Tier-aware thresholds** — Pro alerts at 70%, Max 5x at 94%, Max 20x at 95% (5-hour window) — proportional to how fast each plan burns. - ⏱️ **Either-window-can-kill-you logic** — the 5-hour and 7-day caps are independent ceilings; the policy always acts on the more severe of the two. - 🪪 **Fine-grained plan detection** — uses the `rate_limit_tier` field from local credentials, so it can distinguish `max_5x` from `max_20x` even though the API only returns coarse `pro` / `max`. - 🔐 **Zero extra login** — reuses your existing Claude Code OAuth credentials in `~/.claude/.credentials.json`. - 📦 **Single-file bundle** — pre-built with esbuild, no `npm install` required at install time. - 🛒 **Marketplace ready** — repository ships its own `marketplace.json`, so two slash commands and you're in. ## ⚡ Quick start ```bash # Inside any Claude Code session /plugin marketplace add FruityMaxine/claude-quotas /plugin install claude-quotas@claude-quotas ``` That's it. Claude now has a `check_quota` tool plus a vigilance policy in the bundled skill. From this point on: - For any non-trivial task, Claude takes a **baseline reading** at the start. - It re-checks **periodically** during the work, calibrated by burn rate. - If utilization crosses your plan's **alert zone**, it stays vigilant. - If it crosses the **sleep zone**, it wraps up gracefully, commits, writes a resume note, and `ScheduleWakeup`-sleeps through the reset. - For long autonomous runs (`/loop`), it lowers the trigger by an extra 1% as safety margin. You can also just ask: *"how much of my weekly budget is left?"* and Claude will call the tool directly and answer. ## 📺 What you (and Claude) get back ```text 5-hour session: 38% used | resets in 2h 15m 7-day weekly: 87% used | resets in 3d 4h Plan: max 5x ``` Plus a structured JSON payload with every raw field — `utilization`, `resets_at` (ISO 8601), `subscription_type`, `rate_limit_tier`, per-model windows, `extra_usage` — so Claude can reason over it programmatically. ## 🛠️ Installation options Option A — Marketplace (recommended) ```bash /plugin marketplace add FruityMaxine/claude-quotas /plugin install claude-quotas@claude-quotas ``` Two commands, no clones, automatic updates via `/plugin marketplace update`. Option B — Direct GitHub install ```bash /plugin install github:FruityMaxine/claude-quotas ``` Skips the marketplace step. Use this if you only want this one plugin and don't care about a catalog entry. Option C — Local development ```bash git clone https://github.com/FruityMaxine/claude-quotas.git cd claude-quotas npm install && npm run build claude --plugin-dir ./ ``` The `--plugin-dir` flag loads the plugin from disk, so you can iterate on `src/index.ts` and rerun without publishing. ## 🔍 How it works ```mermaid flowchart LR A[Claude agent] -->|MCP call: check_quota| B[claude-quotas server] B -->|read| C[~/.claude/.credentials.json] C -->|access_token| B B -->|GET /api/oauth/usage| D[(Anthropic OAuth API)] D -->|JSON: 5h / 7d / Opus / extra| B B -->|formatted summary + raw JSON| A ``` 1. The plugin registers an MCP server (`claude-quotas`) that exposes a single tool: `check_quota`. 2. When Claude calls it, the server reads the OAuth credentials Claude Code already wrote during `claude login`. 3. It hits the (undocumented but stable) `GET https://api.anthropic.com/api/oauth/usage` endpoint with the `anthropic-beta: oauth-2025-04-20` header. 4. The response is shaped into both a one-liner summary and a structured JSON object, then handed back to Claude. > **No new credentials, no extra config, no telemetry.** Your token never leaves your machine; the only outbound request is to `api.anthropic.com`. ## 🛡️ Vigilant by design Most "quota tracker" plugins fail in one of two ways: too eager (polling, interrupting, repeated nags) or too passive (the agent doesn't notice the wall coming until it hits it). This one aims for the middle: **measured vigilance** with concrete actions tied to concrete thresholds. ### The three zones The skill defines three zones based on `utilization` (already-used %), per plan: #### 5-hour window | Plan | Alert zone | Sleep + Wrap-up zone | |:-----|:-----------|:---------------------| | **Pro** | `utilization ≥ 70%` | `utilization ≥ 95%` | | **Max 5x** | `utilization ≥ 94%` | `utilization ≥ 98%` | | **Max 20x** | `utilization ≥ 95%` | `utilization ≥ 99%` | #### 7-day window | Plan | Alert zone | Wrap-up zone | |:-----|:-----------|:-------------| | **Pro** | `utilization ≥ 95%` | `utilization ≥ 99%` | | **Max 5x** | `utilization ≥ 98%` | `utilization ≥ 99%` | | **Max 20x** | `utilization ≥ 98%` | `utilization ≥ 99%` | > The 7-day window normally can't be slept through (resets are days away). **Exception**: if the window happens to be in its last 5 hours, the policy treats it like the 5h window — `ScheduleWakeup`-sleeping through the reset (since 5h fits within ScheduleWakeup's 6-segment relay budget). Otherwise Claude wraps up, writes a resume note, and reports back to you instead of trying to sleep. ### What happens at the sleep zone (5h) When the 5-hour window crosses the per-plan sleep threshold, Claude does **all of this** in order, then ends the turn: 1. **Wraps up the current minimal complete unit of work.** No half-edited functions, no broken syntax, no missing braces. Maximize productive output up to the wall — but never leave the codebase in a non-compiling state. 2. **`git commit`s a checkpoint** (no push — pushing is a shared-state action). 3. **Writes a resume note** at `docs/progress/quota-resume.md` with: task summary, completed subtasks, the next concrete subtask (with file paths and line numbers), and any in-flight design context. 4. **`ScheduleWakeup`s** with `delaySeconds = secondsUntilReset` (capped at 3600s by runtime). On wake-up, Claude re-checks `check_quota`; if the window hasn't reset yet, it relay-sleeps another segment (up to 6 segments total). When you come back, your task is either done or right where you left it — never a half-broken file with the agent stuck on a "use extra credits or wait?" dialog. ### Either-window-can-kill-you logic Both windows are independent ceilings — crossing either one ends the session. So the skill always evaluates **both** windows on every check and acts on the **more severe** zone. The 7d wrap-up zone has two sub-routes: if the 7d window is more than 5 hours away from reset, **sleep is forbidden** (sleeping that long isn't viable) and Claude takes the stop route; if it's within 5 hours of reset, Claude sleeps through it just like the 5h sleep route. When both windows need sleeping at once, the wake-up target is the *later* of the two resets so both clear in one go. ### `/loop` awareness In autonomous (`/loop`) contexts the user is typically away from the keyboard. Hitting the wall there pops a blocking dialog that does **not** auto-dismiss when the quota resets — meaning the loop is dead until the user comes back manually. To prevent this, the skill **lowers each sleep threshold by ~1%** when it detects a loop context. The cost of an extra 1% margin is much smaller than the cost of a dead overnight loop. If you'd rather change the policy, edit [`skills/check-quota/SKILL.md`](./skills/check-quota/SKILL.md) — every threshold and every behaviour rule lives there in plain English. ## 🤝 How this fits with other Claude Code usage tools Claude Code already has a healthy ecosystem of mature usage-observation tools. They solve a different problem from this one: - [**ccusage**](https://github.com/ryoppippi/ccusage) (~13.6k ⭐) — a CLI that parses Claude Code's local JSONL transcripts to produce per-day, per-month, and per-session reports of tokens consumed and estimated dollar cost. - [**Claude-Code-Usage-Monitor**](https://github.com/Maciek-roboblog/Claude-Code-Usage-Monitor) (~7.9k ⭐) — a real-time terminal monitor with predictions and warnings. Both are designed for **humans** — they give the user a clear picture of historical or current usage so the user can plan. `claude-quotas` does **not** do any of that. It has no statusline rendering, no per-day reports, no cost analytics, no trend predictions, no menubar app. If those are what you want, those projects do them better than this one ever will. What this plugin does instead: it lets the **Claude agent itself** read its own quota during a multi-step task and follow a policy that wraps up the current unit, commits a checkpoint, and `ScheduleWakeup`-sleeps across the reset before the wall gets hit. It is a tool for the agent, not a dashboard for the user. So the three projects are complementary rather than competing: - Historical analysis and cost tracking → `ccusage` - Real-time dashboard you watch → `Claude-Code-Usage-Monitor` - An agent that manages its own budget during long autonomous tasks → `claude-quotas` ## 🧩 What's in the tool response | Field | Type | Description | |:----- |:---- |:----------- | | `subscription_type` | `string` | Coarse plan from the API: `pro` or `max`. | | `rate_limit_tier` | `string \| null` | Fine-grained tier from local credentials (e.g. `default_claude_max_5x`, `default_claude_max_20x`). Use this when you need to distinguish Max 5x from Max 20x — the API itself doesn't tell you. | | `five_hour.utilization` | `number` (0–100) | % of the 5-hour session used | | `five_hour.resets_at` | `string` (ISO 8601) | When the 5-hour window resets | | `seven_day.utilization` | `number` (0–100) | % of the 7-day weekly cap used | | `seven_day.resets_at` | `string` (ISO 8601) | When the weekly window resets | | `seven_day_opus` | `object \| null` | Opus-specific weekly window. `null` typically means the API didn't surface a pool for this account; a dormant `{utilization: 0, resets_at: null}` means the pool exists but hasn't been consumed in the current 7-day period. | | `seven_day_sonnet` | `object \| null` | Sonnet-specific weekly window. `null` typically means the API didn't surface a pool for this account; a dormant `{utilization: 0, resets_at: null}` means the pool exists but hasn't been consumed in the current 7-day period. | | `extra_usage` | `object \| null` | Pay-as-you-go credit status | | `summary` | `string` | Pre-formatted multi-line human-readable summary | ## 🔐 Privacy & security - Reads **only** your local `~/.claude/.credentials.json` (or whatever `CLAUDE_CONFIG_DIR` points at). - Sends **one** outbound request, to `api.anthropic.com`, identical to what Claude Code itself sends. - Stores **nothing** — no cache, no log file, no analytics. - Source is ~230 lines of TypeScript across three files (`src/lib.ts` shared core, `src/index.ts` MCP server, `src/hook-session-start.ts` resume hook). Auditable in one sitting. ## ❓ FAQ **Q: Why a tool for the agent instead of a UI for me?** Because Claude Code already shows you the numbers in its own UI. The agent is the one who needed help — it was operating blind. This plugin closes that loop. **Q: Does this use a public API?** No. The OAuth usage endpoint is undocumented. It is, however, the same endpoint Claude Code itself uses. If Anthropic ever ships an official one, this plugin will move to it. **Q: Will my credentials leak?** The token only travels to `api.anthropic.com` over TLS, exactly as it does for normal Claude Code traffic. No third-party servers are involved. **Q: What if my token is expired?** The tool returns a non-blocking message and the skill instructs Claude to **silently skip** rather than interrupt your task. You'll only see the error if you explicitly asked for a quota check. Run `claude login` whenever convenient. **Q: Will Claude blast me with quota warnings while I'm working?** No. Vigilance ≠ noise. Claude takes silent baseline readings and re-checks during work, but only takes visible action at threshold zones. In Alert zone, at most a single short transition note. At the Sleep zone, the wrap-up sequence speaks for itself. **Q: What if `ScheduleWakeup` doesn't fire?** That's why the wrap-up sequence does **all three**: commit + resume note + ScheduleWakeup. Even if the wake-up fails (system reboot, session ended, etc.), you have a clean commit and a `docs/progress/quota-resume.md` you can hand back to Claude with "continue from here". The wake-up is an optimization, not a single point of failure. **Q: I want different thresholds / different behaviour.** The whole policy is plain English in [`skills/check-quota/SKILL.md`](./skills/check-quota/SKILL.md). Edit the threshold tables, change the wrap-up steps, disable the loop-strictness bump — fork-friendly. **Q: Why does it say `Plan: max` when I'm actually on Max 5x?** The API only returns coarse `pro` / `max`. The plugin reads `rate_limit_tier` from your local `~/.claude/.credentials.json` to recover the precise tier (`max_5x` / `max_20x`). The summary line shows the fine-grained value automatically. ## 🗺️ Roadmap - [ ] Optional notification hook when crossing a configurable threshold - [ ] Localized summaries (the JSON is universal; only the one-liner is English) - [ ] Per-project usage history via `${CLAUDE_PLUGIN_DATA}` - [ ] Add a slash command (`/quota`) for human-initiated checks PRs welcome.
