## What it does

The skill pulls the session list, per-session events and daily analytics trends, then drops everything into 24 hourly and 7 weekday buckets. Output is Markdown: text bars such as `09:00 ████████ 24`, plus tables with completion rate, average cost and the model that dominates each day.

Busy hours and productive hours are counted separately. A slot can be packed with sessions and still show short fragmented turns, and the report keeps those apart. Low-output windows are backed by error and compaction timing taken from the event stream.

Arguments can be left empty, set to a window like “last 30 days”, or pointed at a project path to scope the run to one `cwd`. Sessions missing `started_at` or the focus metadata are skipped, and their count is reported. Costs come out in USD with 4 decimals; durations are converted from ms to minutes.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install hoangsonww/Claude-Code-Agent-Monitor time-of-day
```

2. **Manually: put the files in place**
- File: `.github/skills/time-of-day/SKILL.md`

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/hoangsonww/Claude-Code-Agent-Monitor --path plugins/ccam-productivity/skills/time-of-day
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add hoangsonww/Claude-Code-Agent-Monitor --skill time-of-day -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-productivity/skills/time-of-day/SKILL.md

## When to use it
- see which hours finish sessions instead of abandoning them
- tell heavy hours apart from genuinely productive ones
- line up API errors and compactions with the time of day
- pick a block for deep work and one for shallow tasks
- compare weekdays by cost and dominant model

## Example prompts
- Show my activity by hour for the last 30 days
- Break down the weekday pattern for `~/work/api`
- Which windows are low-output because of errors and compactions?

  Discover when you are most active and most productive with Claude Code by
  bucketing sessions and events into hour-of-day and day-of-week bins from their
  timestamps, then flagging peak versus low-output windows. Uses the session
  list, per-session events, and analytics daily trends. Use when planning a
  schedule or deciding when to do deep work versus lighter tasks.

# Time of Day

Profile activity and productivity across the hours of the day and days of the week.

## Input

The user provides: **$ARGUMENTS**

This may be:
- empty or "all" (default: all available sessions)
- a window like "last 30 days" or "last 90 days" to limit the analysis
- a project path to scope the analysis to one `cwd`

## Data Sources

| Endpoint | Returns |
|----------|---------|
| `GET /api/sessions?limit=500` | Sessions with `started_at`, `ended_at`, `status`, `cwd`, `cost`, and `metadata` (turn_count, total_turn_duration_ms) — primary source for hour/weekday bucketing |
| `GET /api/events?session_id=X` | Events with `timestamp` and `event_type` (PreToolUse, PostToolUse, Stop, Compaction, APIError, etc.) — finer-grained activity within sessions and error timing |
| `GET /api/analytics` | `daily_sessions` / `daily_events` (365d) and `sessions_by_status` for trend context and completion baselines |

## Report Sections

### 1. Activity by Hour of Day
Bucket sessions (by `started_at`) and events (by `timestamp`) into 24 hourly bins.
Show a text bar chart of session and event counts per hour. Identify the busiest
hours by raw volume.

### 2. Productivity by Hour of Day
For each hour bin, compute completion rate (`completed / total` sessions started in
that hour) and average sustained turn time
(`total_turn_duration_ms / turn_count`, ms → minutes). Distinguish "active" hours
(high volume) from "productive" hours (high completion + sustained turns).

### 3. Day-of-Week Pattern
Bucket the same metrics into 7 weekday bins. Table: weekday, sessions, completion
rate, avg cost, dominant model.

### 4. Peak vs. Low-Output Windows
- **Peak windows:** hours/days with high completion rate and long sustained turns.
- **Low-output windows:** hours/days with high abandonment/error/Compaction rates
  or fragmented short turns. Pull error timing from `/api/events` event types
  (APIError, Compaction) to corroborate.

### 5. Schedule Recommendation
Suggest which hour/weekday blocks to reserve for deep work and which to use for
lighter or shallower tasks, grounded in the buckets above.

## Output

- Markdown with text-based bar charts (e.g., `09:00 ████████ 24`) for the hourly
  and weekday distributions.
- Tables for the hour and weekday metrics; ▲ / ▼ for above/below the overall mean.
