Need help deploying deep-history?
Chalk Labs sets up agents like this inside real teams: connected to your tools, tested on your data, with a human in the loop where it matters.
Install
Works with Claude Code, Claude apps, Codex, Cursor, Gemini CLI, GitHub Copilot, VS Code, OpenCode, Goose, Windsurf. Read the repository before you give any tool access to your data.
npx agentmarket install skill/sungmin-cho-deep-history
Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

## Inputs (skill args)
| 인자 | 의미 |
|---|---|
| (없음) | Default — 전체 세션 이력 + aggregate stats |
빈 args / 매칭되지 않는 토큰 → 본문의 default 분기로 진입.
## Prerequisites
**Hub-spoke 관계**: 본 skill 은 `deep-status` hub 의 sub-page 입니다 — `/deep-status --<flag>` 가 본문 로직을 inline Read 하여 실행하는 것이 주 경로이며, 직접 호출도 동일하게 지원됩니다.
> **Internal** — `/deep-status --history`가 이 파일의 로직을 `Read`하여 실행합니다. 자동 호출이 주 경로이며, 직접 호출도 지원됩니다.
> 참조처: `${CLAUDE_PLUGIN_ROOT}/skills/deep-status/SKILL.md` §7 (`Read ${CLAUDE_PLUGIN_ROOT}/skills/deep-history/SKILL.md and follow its display logic inline`).
# Deep Work Session History
View historical session data across all completed Deep Work sessions.
## Language
Read(`${CLAUDE_PLUGIN_ROOT}/skills/shared/references/user-language.md`) and follow it.
## Instructions
### 1. Scan for session receipts
Search for `session-receipt.json` files in all deep-work output directories:
```bash
find . -path "*/.deep-work/*/session-receipt.json" -type f 2>/dev/null | sort -r
```
If no session receipts found:
```
ℹ️ 세션 이력이 없습니다.
/deep-work로 세션을 시작하고 /deep-finish로 완료하면 이력이 기록됩니다.
```
Stop here.
### 2. Parse all session receipts
For each `session-receipt.json`, extract:
- `session_id`, `task_description`, `started_at`, `finished_at`
- `outcome` (merge/pr/keep/discard)
- `slices.total`, `slices.completed`
- `tdd_compliance` (strict/relaxed/override/spike/coaching counts)
- `model_usage` (haiku/sonnet/opus/main counts)
- `evaluation.evaluator_model` (haiku/sonnet/opus — the model used for plan/test evaluation)
- `total_estimated_cost`
- `deep_work_version`
### 3. Display session list
```
Deep Work Session History
┌────┬──────────────────────┬────────────┬────────┬──────────┬───────────┬───────────┐
│ # │ Task │ Date │ Slices │ Outcome │ Model │ Evaluator │
├────┼──────────────────────┼────────────┼────────┼──────────┼───────────┼───────────┤
│ 1 │ Add model routing │ 2026-03-25 │ 4/4 │ PR #42 │ S1 H2 O1 │ sonnet │
│ 2 │ Fix receipt bug │ 2026-03-23 │ 2/2 │ merge │ S2 │ haiku │
│ 3 │ Worktree setup │ 2026-03-20 │ 3/5 │ keep │ S3 │ sonnet │
└────┴──────────────────────┴────────────┴────────┴──────────┴───────────┴───────────┘
S=sonnet H=haiku O=opus M=main
Evaluator: evaluation.evaluator_model from session receipt (or "—" if not set)
```
### 4. Display aggregate statistics
```
Aggregate Stats (최근 [N]개 세션)
TDD 준수율: strict [N]% | relaxed [N]% | override [N]% | spike [N]%
모델 사용: haiku [N]회 | sonnet [N]회 | opus [N]회
평가자 모델 사용: haiku [N]회 | sonnet [N]회 | opus [N]회
완료율: [completed]/[total] 슬라이스 ([N]%)
결과: merge [N] | PR [N] | keep [N] | discard [N]
```
If `estimated_cost` data is available:
```
예상 비용: 총 $[N] (세션 평균 $[N])
```
### 5. Trend indicator
Compare the most recent 3 sessions to the 3 before that (if available):
```
트렌드 (최근 3 vs 이전 3)
TDD strict 비율: [N]% → [N]% [↑/↓/→]
완료율: [N]% → [N]% [↑/↓/→]
평균 슬라이스: [N]개 → [N]개 [↑/↓/→]
