dsh-workspace-history

A DeepSeek Harness (DSH)
plugin: every compaction summary (auto-compaction or /compact) is
journaled into the workspace of the session that compacted, and a History
subtab reads the journal back.

<workspace>/.dsh/history/<unix-ts>.<short-session-id>.md

• One file per compaction, named by the compaction's own unix
  timestamp: ls reads as the project's chronological timeline, and
  ls *0a57a14f* isolates one session. Full session id, workspace, and
  counts live in each file's header.
• History subtab: with dsh-workspace-overview
  installed, a History subtab appears in the Workspace Overview tab: the
  journal listed newest first on the left, the picked entry rendered as
  markdown on the right. Entries load one at a time, on selection.
• Per-session toggle (default on): "Save compaction history" lives in
  the granular Settings tab; its store is the single source of truth.
• Failure-only diagnostics land in .dsh/history/.diag.log.

How to install

Requires a DeepSeek Harness checkout and a profile, here web. Clone the
dependencies and this plugin into a plugins folder:

mkdir -p ~/dsh-plugins && cd ~/dsh-plugins
git clone https://github.com/joao-paulo-santos/dsh-granular-settings.git
git clone https://github.com/joao-paulo-santos/dsh-workspace-overview.git
git clone https://github.com/joao-paulo-santos/dsh-workspace-history.git

# from the harness checkout
pnpm dsh plugin --profile web add ~/dsh-plugins/dsh-granular-settings
pnpm dsh plugin --profile web add ~/dsh-plugins/dsh-workspace-overview
pnpm dsh plugin --profile web add ~/dsh-plugins/dsh-workspace-history

# verify the profile still composes
pnpm dsh --profile web --dump-config

Restart the harness; the History subtab appears in Workspace Overview.

Dependencies

• dsh-granular-settings hosts the "Save compaction history" session toggle (required; without it the plugin does not run, because the toggle is the only control surface)
• dsh-workspace-overview hosts the History subtab (optional; the journal keeps writing without it, the client half simply stays inactive)
• dsh-md-view renders journal bodies as markdown (optional; without it bodies show as plain text)

Notes for plugin authors

• The fs service is the SandboxedFileSystem: writeText without a
  per-call sandbox policy is denied even inside the workspace. Every write
  here passes { mode: 'workspace-write', workspaceRoot: <journal dir> }.
• session/event delivers the envelope { type, seq, time, data }; the
  payload lives under event.data. Session workspace: session.header.cwd.
• Consuming another plugin's service is ctx.get('granularSettings') with
  an undefined check: degrade gracefully when it is absent (as done here).
