## What it does

The skill aggregates Claude Code activity across projects using data from Agent Monitor. It queries the `/api/run/cwds`, `/api/sessions?limit=1000`, and `/api/pricing/cost` endpoints. Everything groups by working directory. For each folder, it tallies session counts, total dollar cost, active models, and latest timestamps. Token sums separate billable text from cache reads and writes.

Output comes as a Markdown table sorted by cost descending. It shows each directory's share of total fleet spend. You can pass a path substring to filter rows or use `top N` to limit results. The skill requires an active Agent Monitor instance; if the local dashboard is down, start it with `npm start` in the repository root. Sessions missing `usage_extras` metadata are simply excluded from token sums.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add hoangsonww/Claude-Code-Agent-Monitor --skill cwd-rollup -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/cwd-rollup/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/cwd-rollup/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add hoangsonww/Claude-Code-Agent-Monitor --skill cwd-rollup -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/cwd-rollup/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add hoangsonww/Claude-Code-Agent-Monitor --skill cwd-rollup -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/cwd-rollup/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install hoangsonww/Claude-Code-Agent-Monitor cwd-rollup
```

2. **Manually: put the files in place**
- File: `.github/skills/cwd-rollup/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add hoangsonww/Claude-Code-Agent-Monitor --skill cwd-rollup -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/hoangsonww/Claude-Code-Agent-Monitor --path plugins/ccam-sessions/skills/cwd-rollup
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/cwd-rollup/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add hoangsonww/Claude-Code-Agent-Monitor --skill cwd-rollup -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/hoangsonww/Claude-Code-Agent-Monitor/tree/HEAD/plugins/ccam-sessions/skills/cwd-rollup/SKILL.md

## When to use it
- Compare Claude Code spend across different working directories
- Find projects with the highest token consumption and dollar cost
- Check recent activity timestamps and model usage for a folder
- Calculate each project's percentage share of total fleet spend

## Example prompts
- Roll up Claude Code sessions across all working directories
- Show top 5 most expensive projects using cwd-rollup
- Filter directory rollup for paths matching backend

  Roll up Claude Code sessions by working directory (project) from Agent Monitor
  data — session count, total cost, total tokens, and last-active timestamp per cwd
  — so per-project activity can be compared at a glance. Use when summarizing where
  effort and spend went across projects.

# CWD Rollup

Aggregate session activity per working directory (project).

## Input

The user provides: **$ARGUMENTS**

- Empty → roll up **all** working directories.
- A path / project substring → restrict the rollup to matching cwds.
- `top N` → keep only the N highest-cost (or highest-count) projects.

## Data Sources

| Endpoint | Returns |
|----------|---------|
| `GET /api/run/cwds` | the distinct working directories that have sessions — the rollup key set |
| `GET /api/sessions?limit=N` | session list: id, status, model, cwd, started_at, ended_at, cost, metadata (usage_extras with token counts) |
| `GET /api/pricing/cost` | fleet cost: total_cost, breakdown[{ model, input_tokens, output_tokens, cache_read_tokens, cache_write_tokens, cost, matched_rule }] — for the fleet total to compute each cwd's share |

## Report Sections

### 1. Key set
`GET /api/run/cwds` for the canonical list of working directories. Apply the
`$ARGUMENTS` filter (substring match) if one was given.

### 2. Pull sessions
`GET /api/sessions?limit=1000`. Bucket sessions by `cwd`.

### 3. Aggregate per cwd
For each working directory compute:
- **sessions** — count.
- **cost** — sum of the inline `cost` field across the bucket.
- **tokens** — sum of input / output / cache-read / cache-write from each session's
  metadata `usage_extras` (sum the four into a total, and keep input + output as the
  "billable text" subtotal).
- **last active** — the max `started_at` (or `ended_at`) in the bucket.
- **models** — the distinct models seen.

### 4. Share of fleet
`GET /api/pricing/cost` for `total_cost`; show each cwd's cost as a percentage of the
fleet total.

### 5. Ranking
Sort by cost descending by default (or count if the user asked); apply `top N`.

## Output

Markdown table: `project (cwd basename) | sessions | total tokens | cost | % of fleet | last active | models`.
Currency as USD to 4 decimal places; token counts with thousands separators; sort
cost-descending. Add a final TOTAL row summing the columns. Only count tokens that
the session metadata actually carries — if `usage_extras` is absent for a session,
note it as excluded rather than guessing. If the dashboard is unreachable, tell the
user to start it with `npm start` from the repo root.
