dsh-showcase turns a DeepSeek Harness session into a redacted, animated README demo

English

GitHub-ready demos from DeepSeek Harness sessions. dsh-session-showcase turns an official DeepSeek Harness (DSH) session export, raw JSONL log, or Zstandard session log into a polished animated WebP/GIF, poster, social preview, README snippet, and machine-readable manifest. It can run as a standalone CLI or as a native DSH tool plugin.

It runs locally, executes no session tools, uploads nothing, and makes zero AI/model calls.

For DSH, install the GitHub package into the profile you use:

dsh plugin --profile <profile> add github:STFQ/dsh-showcase

The plugin registers dsh_showcase. It reads a local session export through DSH's filesystem provider, writes to the local workspace, and never uploads the session or calls a model.

Why this exists

DSH records semantic events—prompts, tool calls, diffs, results, and final answers. A screen recorder sees pixels; dsh-session-showcase sees those events and turns the useful moments into a short, repeatable story for a GitHub README, plugin launch, issue, or release.

Screen recorder Replay viewer dsh-session-showcase
Input Pixels Full transcript Semantic DSH events
Output Long video Interactive debugger Short README-ready animation
Secret handling Manual Varies Redaction on by default
Model/API usage None Varies None

Quick start

Requirements: Node.js 22.19 or newer. No FFmpeg and no API key are required.

Try it immediately (no DSH account or API key)

Render the included safe fixture first. This proves the complete output path in about 10 seconds:

git clone https://github.com/STFQ/dsh-showcase.git
cd dsh-showcase
npm install
npm run build
node dist/cli.js examples/session.jsonl --output ./showcase --format both

Render a real DSH session

  1. In the DSH Web UI, run /export in the session you want to share. DSH downloads an official session ZIP.
  2. Install the plugin into the profile you use:
dsh plugin --profile <profile> add github:STFQ/dsh-showcase

The plugin registers the dsh_showcase tool. Ask DSH to render the exported ZIP, for example:

Use dsh_showcase on dsh-session-<id>.zip. Write both WebP and GIF to ./.dsh/showcase,
use the default automatic redaction, and return the generated artifact paths.
  1. If you only need the standalone CLI, install the package after the next npm release:
npm install --global dsh-session-showcase
  1. Render it locally:
dsh-showcase dsh-session-<id>.zip --output ./showcase
  1. Copy the generated snippet into your README:
showcase/
├── hero.webp
├── poster.png
├── social-preview.png
├── README-snippet.md
└── showcase.manifest.json

Generate both animated WebP and GIF:

dsh-showcase session.jsonl --format both --theme midnight

Preview scene selection and redaction without writing files:

dsh-showcase session.jsonl --dry-run --json

What it reads

  • Official DSH session export ZIP (session.jsonl at the archive root)
  • Raw DSH session.jsonl
  • Default concatenated-frame session.jsonl.zstd
  • Packed text-chunks, reasoning-chunks, and tool-call-chunks storage rows
  • Standard input with -

Version 0.2 adds the DSH plugin entry point while keeping the standalone CLI. It renders the root session and reports included subagent logs without rendering them. See the verified compatibility contract.

Privacy and redaction

Redaction is enabled by default and covers common API keys, GitHub tokens, JWTs, bearer tokens, secret assignments, email addresses, credentialed URLs, and home-directory paths.

# Redact and continue (default)
dsh-showcase session.jsonl --redact auto

# Fail before writing when anything sensitive is detected
dsh-showcase session.jsonl --redact strict

# Disable only after reviewing the source
dsh-showcase session.jsonl --redact off

Reasoning blocks and request headers are never selected as showcase scenes. Redaction is defense in depth, not a guarantee; review generated artifacts before publishing. Read the security and privacy model.

Automation and agents

--json keeps stdout machine-only; warnings and errors go to stderr. The versioned result is described by schemas/result.schema.json.

dsh-showcase session.jsonl --dry-run --json > plan.json

Agent entry points:

  • llms.txt: compact product and documentation map
  • docs/cli.md: complete CLI and exit-code contract
  • docs/plugin.md: DSH plugin installation and tool contract
  • docs/session-format.md: verified DSH adapter contract
  • schemas/manifest.schema.json: generated manifest contract
  • AGENTS.md: contributor-agent instructions

Common options

Option Meaning
-o, --output <dir> Output directory
--format webp|gif|both Animated output format
--theme deepsea|midnight|paper Visual theme
--redact auto|strict|off Secret handling policy
--title <text> Cover-title override
--max-scenes <2-8> Scene count including the cover
--dry-run Parse and inspect without writing
--overwrite Replace known generated files
--json Versioned machine-readable stdout

Design references

This project follows the DSH session/export contract pinned to the verified rc.8 revision and established CLI conventions rather than inventing an incompatible transcript format. The exact upstream sources and mature projects reviewed are recorded in docs/design.md. Code adapted from DeepSeek Harness retains its MIT notice in THIRD_PARTY_NOTICES.md.

Contributing and security

See CONTRIBUTING.md. Please use GitHub private vulnerability reporting as described in SECURITY.md; if it is unavailable, open an issue without exploit details or private data to request a private channel.

dsh-session-showcase is an independent community project and is not affiliated with or endorsed by DeepSeek. DeepSeek and DeepSeek Harness are referenced only to describe compatibility.


简体中文

把 DeepSeek Harness 会话变成可直接放进 GitHub README 的演示素材。 dsh-session-showcase 可以读取 DeepSeek Harness(DSH)官方导出的会话 ZIP、原始 JSONL 或 Zstandard 会话日志,生成精致的 WebP/GIF 动图、封面、社交预览图、README 片段和机器可读清单;它既可以作为独立 CLI,也可以作为 DSH 原生工具插件运行。

它完全在本地运行,不执行会话中的工具、不上传数据,且 不会调用任何 AI 模型,不消耗 Token。

在 DSH 中,请把 GitHub 包安装到你使用的 profile:

dsh plugin --profile <profile> add github:STFQ/dsh-showcase

插件会注册 dsh_showcase 工具,通过 DSH 文件系统读取本地会话并写入本地工作区,不上传会话,也不调用模型。

为什么做这个项目

DSH 会记录提示词、工具调用、代码差异、执行结果和最终回答等语义事件。录屏工具看到的是像素,而 dsh-session-showcase 能理解这些事件,并把真正有价值的节点整理成一段简短、可重复生成的故事,适合放在 GitHub README、插件发布帖、Issue 或 Release 中。

录屏工具 会话回放器 dsh-session-showcase
输入 屏幕像素 完整会话 DSH 语义事件
输出 较长视频 交互式调试页面 README 可用的短动图
敏感信息处理 手动 各不相同 默认自动脱敏
模型/API 消耗 无 各不相同 无

快速开始

需要 Node.js 22.19 或更高版本,不需要 FFmpeg,也不需要 API Key。

立即试用(无需 DSH 账号或 API Key)

先用仓库内置的安全示例生成完整产物,约 10 秒即可确认流程:

git clone https://github.com/STFQ/dsh-showcase.git
cd dsh-showcase
npm install
npm run build
node dist/cli.js examples/session.jsonl --output ./showcase --format both

生成真实 DSH 会话演示

  1. 在 DSH Web 界面的目标会话中运行 /export,下载官方会话 ZIP。
  2. 把插件安装到你使用的 profile:
dsh plugin --profile <profile> add github:STFQ/dsh-showcase

插件会注册 dsh_showcase 工具。可以这样请求 DSH 生成演示:

使用 dsh_showcase 处理 dsh-session-<id>.zip,把 WebP 和 GIF 都写入 ./.dsh/showcase,
使用默认的自动脱敏,并返回生成文件的路径。
  1. 如果只需要独立 CLI,等待下一版 npm 包发布后安装:
npm install --global dsh-session-showcase
  1. 在本地生成演示:
dsh-showcase dsh-session-<id>.zip --output ./showcase
  1. 把生成的 README 片段复制到你的项目:
showcase/
├── hero.webp
├── poster.png
├── social-preview.png
├── README-snippet.md
└── showcase.manifest.json

同时生成 WebP 和 GIF:

dsh-showcase session.jsonl --format both --theme midnight

只检查场景选择和脱敏结果,不写文件:

dsh-showcase session.jsonl --dry-run --json

支持的输入

  • DSH 官方会话导出 ZIP(根目录包含 session.jsonl)
  • 原始 DSH session.jsonl
  • 默认的多帧 session.jsonl.zstd
  • text-chunks、reasoning-chunks、tool-call-chunks 压缩存储行
  • 使用 - 从标准输入读取

0.2 版本新增 DSH 插件入口,同时保留独立 CLI;它会渲染根会话,并报告 ZIP 中的子 Agent 日志数量,但暂不渲染子 Agent。具体范围见已验证的兼容性契约。

隐私与脱敏

脱敏默认开启,覆盖常见 API Key、GitHub Token、JWT、Bearer Token、密钥赋值、邮箱、带凭据 URL,以及用户主目录路径。

# 自动脱敏并继续(默认)
dsh-showcase session.jsonl --redact auto

# 一旦检测到敏感值,在写文件前停止
dsh-showcase session.jsonl --redact strict

# 仅在你已检查源文件时关闭
dsh-showcase session.jsonl --redact off

推理内容和请求头不会被选为演示场景。脱敏只是纵深防御,并非绝对保证;公开前仍应检查生成物。详见安全与隐私模型。

自动化与 Agent

使用 --json 时,stdout 只输出机器可读 JSON,警告和错误进入 stderr。稳定结果结构见 schemas/result.schema.json。

dsh-showcase session.jsonl --dry-run --json > plan.json

面向 Agent 的入口:

  • llms.txt:精简的产品与文档导航
  • docs/cli.md:完整 CLI 与退出码契约
  • docs/plugin.md:DSH 插件安装方式与工具契约
  • docs/session-format.md:已核验的 DSH 格式适配说明
  • schemas/manifest.schema.json:生成清单的数据契约
  • AGENTS.md:贡献代码时的 Agent 指令

常用参数

参数 含义
-o, --output <目录> 输出目录
--format webp|gif|both 动图格式
--theme deepsea|midnight|paper 视觉主题
--redact auto|strict|off 敏感信息处理策略
--title <文本> 自定义封面标题
--max-scenes <2-8> 包含封面在内的场景数
--dry-run 只解析检查,不写文件

设计参考

本项目遵循已固定到 rc.8 并完成核验的 DSH 会话与导出契约,同时参考成熟 CLI 规范,没有另造不兼容的会话格式。核验过的上游来源和参考项目记录在 docs/design.md。从 DeepSeek Harness 适配的代码在 THIRD_PARTY_NOTICES.md 中保留了 MIT 声明。
