# AI Tool Conversation History Summary

Analyze AI tool conversation histories for a given period and generate themed work summaries.

## Scheduling

### Goal
Collect AI tool conversation history for a date or window and synthesize it into a themed, project-oriented recap with saved Markdown output.

### Intent signature
- User asks for daily recap, weekly/monthly summary, standup notes, work log, tool usage pattern, or AI conversation history analysis.
- User wants conversation histories grouped by work content rather than raw chronological logs.

### When to use
- Summarizing a day or period of work activity
- Understanding the overall flow of work across multiple AI tools
- Analyzing tool-switching patterns between sessions
- Preparing daily standups, weekly retros, or work logs

### When NOT to use
- Git commit-based code change retrospective -> use `oma retro`
- Real-time agent monitoring -> use `oma dashboard`
- Productivity metrics -> use `oma stats`

### Expected inputs
- Date, relative date, time window, or tool filter
- Conversation history available through `oma recap --json` or fallback sources
- Desired daily or multi-day recap scope

### Expected outputs
- Markdown recap saved to `.agents/results/recap/{date}.md` or range filename
- TL;DR, overview, themes/projects, miscellaneous or side projects, and tool usage patterns
- User-facing summary in configured response language

### Dependencies
- `oma recap --json`
- Optional Claude fallback history at `~/.claude/history.jsonl`
- `.agents/oma-config.yaml` for language behavior

### Control-flow features
- Branches by date resolution, window length, available tool history, and daily vs multi-day output shape
- Reads local history data and writes Markdown recap files
- Groups by content, not by tool

## Structural Flow

### Entry
1. Resolve requested date or window.
2. Collect normalized conversation history.
3. Decide daily versus multi-day output structure.

### Scenes
1. **PREPARE**: Resolve time range and tool filters.
2. **ACQUIRE**: Collect history through CLI or fallback.
3. **REASON**: Group by content, infer themes/projects, decisions, artifacts, and tool-switching patterns.
4. **ACT**: Write recap Markdown in the required format.
5. **VERIFY**: Check TL;DR, grouping, language, and output path.
6. **FINALIZE**: Save and display summary.

### Transitions
- If no date is specified, use today.
- If window is 3 days or longer, group by project instead of day chronology.
- If CLI is unavailable, use Claude fallback only and report scope limits.
- If tasks are under threshold, group them into Miscellaneous or Side Projects.

### Failure and recovery
- If history is unavailable, report missing source and requested range.
- If timestamps are ambiguous, use configured timezone and state assumption.
- If extracted data is sparse, produce a concise recap and note limited coverage.

### Exit
- Success: recap file exists and summary is displayed.
- Partial success: missing tools/history or fallback-only coverage is explicit.

## Logical Operations

### Actions
| Action | SSL primitive | Evidence |
|--------|---------------|----------|
| Resolve date/window | `INFER` | Natural-language date rules |
| Collect history | `CALL_TOOL` | `oma recap --json` or `jq` fallback |
| Read extracted records | `READ` | Conversation history |
| Group themes/projects | `INFER` | Time/content grouping rules |
| Validate output shape | `VALIDATE` | Daily or multi-day template |
| Write recap | `WRITE` | `.agents/results/recap/` |
| Report summary | `NOTIFY` | Displayed recap |

### Tools and instruments
- `oma recap --json`
- `jq` fallback for Claude history
- Markdown output templates

### Canonical command path
```bash
oma recap --json
oma recap --window 7d --json
oma recap --date YYYY-MM-DD --json
```

### Resource scope
| Scope | Resource target |
|-------|-----------------|
| `LOCAL_FS` | Conversation history and recap output files |
| `PROCESS` | `oma recap`, `jq`, date commands |
| `USER_DATA` | Conversation prompts and project activity |
| `MEMORY` | Theme grouping and summary notes |

### Preconditions
- Requested time range can be resolved.
- At least one history source is available.

### Effects and side effects
- Writes recap Markdown under `.agents/results/recap/`.
- Reads local conversation history data.

### Guardrails

### Process

### 1. Resolve Date

Determine the target date or window from the user's natural language input. Default is today.

**Resolution rules:**
- Relative day references (today, yesterday, day before yesterday, etc.) → calculate `--date YYYY-MM-DD`
- Specific date mentions (month + day, or full date) → convert to `--date YYYY-MM-DD`
- Relative weekday references (last Monday, this Friday, etc.) → calculate the date
- Period references (this week, last 3 days, past 2 weeks, etc.) → convert to `--window Nd`
- No date specified → today (`--window 1d`)

### 2. Collect Data

Extract normalized conversation history via CLI.

```bash
# Default (today, all tools)
oma recap --json

# Time window
oma recap --window 7d --json

# Specific date
oma recap --date 2026-04-10 --json

# Tool filter
oma recap --tool claude,gemini --json
```

**Fallback when CLI is not installed** — process Claude history only via inline jq:

```bash
TARGET_DATE=$(date +%Y-%m-%d)
TZ=Asia/Seoul start_ts=$(date -j -f "%Y-%m-%d %H:%M:%S" "${TARGET_DATE} 00:00:00" +%s)000
end_ts=$((start_ts + 86400000))

TZ=Asia/Seoul jq -r --argjson start "$start_ts" --argjson end "$end_ts" '
  select(.timestamp >= $start and .timestamp < $end and .display != null and .display != "") |
  {
    time: (.timestamp / 1000 | localtime | strftime("%H:%M")),
    project: (.project | split("/") | .[-1]),
    prompt: (.display | gsub("\n"; " ") | if length > 150 then .[0:150] + "..." else . end)
  }
' ~/.claude/history.jsonl
```

### 3. Theme Analysis and Grouping

Read **all** extracted data and analyze with the following criteria:

**Grouping rules:**
