The tools
sync-hubbetaDSH Sync Hub
Sync DSH sessions across machines
You get: the same session list on both machines, with titles, and a conflict copy instead of a lost session.
How it works →zstd-frame-inspectorstableZstd Frame Inspector
See inside a growing .zstd session file
You get: how many append batches a session file holds, and how big the next sync would be.
See a sample result →context-budgetstableContext Budget
How many turns before the context blows up
You get: the turn number where you should compact, and whether you have room for one more task.
See a sample result →session-index-doctorstableSession Index Doctor
Why a session is missing from the list
You get: the exact session ids that exist on disk but will never appear in the list.
See a sample result →skill-load-auditstableSkill Load Audit
Which skill is eating your context
You get: tokens per skill, ranked, so you know what to archive before it costs you a window.

Check text and UI for template traces
You get: the exact lines that read like a template, and one sentence on how to fix each.

Why these five
The list and the file are two different things
On one install with 114 sessions on disk, the workspace index knew 38 ids. The other 76 were invisible in the app. Printing that gap is what the Doctor is for.
Nobody wrote the format down
A session is an append-only stream of zstd frames, and one file here reached 22,832,359 bytes. The Inspector counts frames because that number explains why a sync feels slow.
These files are your conversations
So nothing is uploaded. Each tool is a page with JavaScript in it, and the only thing you download is a command-line tool you run yourself.
FAQ
Do I need to install anything?
No. Every tool is a static page. DSH Sync Hub itself is a command-line tool you download and self-host — still free.
Are my files uploaded?
Never. The inspector and calculator are plain JavaScript in the page; there is no backend to send to.
What is DSH?
DeepSeek Harness — a local agent runtime with web, desktop and terminal builds. It stores sessions on disk, which is why cross-machine sync is a problem at all.
