DSH Share

Privacy-first Markdown and self-contained HTML sharing for DeepSeek Harness Sessions. DSH Share is an independent community plugin.

简体中文

DSH Share adds a Share action to the Web Session header. It creates a local preview, then lets you copy the generated source or download it. Nothing is uploaded and the plugin makes no outbound request.

Why DSH Share

The official Session log export is the right lossless ZIP for diagnosis and migration. DSH Share produces a smaller, human-readable document for review, issue reports, and knowledge sharing.

• Markdown or one script-free HTML file
• Best-effort redaction enabled by default
• Preview before copy or download
• Tool calls opt-in and collapsed
• No cloud service, account, or public-link backend
• Zero model-visible text and zero model-token overhead

Install

DSH is currently a developer preview. Install the tagged GitHub bundle into the Web profile:

dsh plugin --profile web add github:ChuanTianML/dsh-share#v0.1.0
dsh --profile web

Open a non-empty Session and select Share in its header.

To remove the plugin:

dsh plugin --profile web remove dsh-share

Privacy behavior

The default document contains only direct human prompts and visible assistant text in log order.

Content	Default	Optional
Human prompts	Included	—
Visible assistant text	Included	—
Tool names, bounded arguments, outcomes	Excluded	Enable “Include tool calls”
Tool result bodies	Excluded	Never included
Reasoning / thinking	Excluded	Never included
System prompts and request configuration	Excluded	Never included
Plugin-injected user-role context	Excluded	Never included
Attachment bytes and Session metadata	Excluded	Never included

Redaction covers common credentials, authorization headers, secret-bearing environment assignments, email addresses, and absolute local paths. It is heuristic, not a guarantee. Always review the preview. If redaction is disabled, copy and download remain locked until a fresh risk acknowledgement is checked.

The preview runs in a sandboxed srcdoc iframe. Generated HTML has no scripts or external resources and carries a restrictive Content Security Policy.

Host configuration

All resource limits are validated when the plugin loads.

Field	Default	Meaning
maxEvents	20000	Maximum raw Session events accepted
maxOutputChars	2000000	Maximum file or preview characters
maxToolArgumentChars	12000	Maximum retained arguments per enabled tool call

Session and output overflows fail visibly. Tool arguments alone may be truncated, with a warning in the preview.

Development

The verified Harness revision is 47f943859bef60e4160492346772ded9b24f765a. Keep the checkout isolated under .sandbox/harness:

corepack enable
pnpm install
git clone https://github.com/deepseek-ai/deepseek-harness.git .sandbox/harness
git -C .sandbox/harness checkout 47f943859bef60e4160492346772ded9b24f765a
pnpm --dir .sandbox/harness install --frozen-lockfile
pnpm --dir .sandbox/harness run build
pnpm run check

DSH_HARNESS_ROOT=/absolute/path/to/deepseek-harness selects another read-only development checkout. pnpm run check runs strict type checks, ESLint, unit and composition tests, Host/browser builds, and a package dry run. Built lib/ artifacts are committed because profile installs do not run a build step.

The complete product and security design is in docs/design.md.

Compatibility

Version 0.1.0 targets the DSH developer-preview API at the verified revision above. DSH does not yet promise stable external plugin compatibility; future Harness changes may require a new DSH Share release.

Security

See SECURITY.md. Never include a real credential or private Session in a public issue.
