Plugins

A chemistry workbench panel in the DSH web UI. Draw structures on a Ketcher canvas (a script downloads the build; it renders locally in the browser with no backend), then compute on the current molecule with RDKit without calling a model — formula, molecular weight, exact mass, logP, TPSA, hydrogen-bond donors and acceptors, ring counts, Fsp3, stereocentres, Lipinski and Veber rule-by-rule checks, QED, PAINS/BRENK structural alerts and the Murcko scaffold, plus SMARTS substructure matching, fingerprint similarity, format conversion, standardisation and batch clean-up. A retrosynthesis tab talks to a pluggable backend (Retro* by default) over a single JSON-in/JSON-out process, and states what is missing when the backend is not installed instead of inventing a route. The calculations run in this repository's Python package (rdkit), which is installed with pip separately.

Registers the dsh-mol stdio MCP server, built on RDKit with no network access, into a DSH profile. It exposes 12 tools: three-level SMILES validation with human-readable diagnostics and character positions, molecular properties, drug-likeness and structural alerts, structure rendering to PNG/SVG, multi-molecule grids, format conversion (SMILES, InChI, InChIKey, MOL, SDF, formula), standardisation with a per-step change log, deduplication, SMARTS substructure matching, fingerprint similarity, and batch clean-up that reports every rejected row. The patch only registers the server; the tools live in this repository's Python package and must be installed first — the README gives a `pip install` route and a from-source route, and until the package is on PyPI the from-source one is what works.

Session cleanup for the DSH sidebar: drag a conversation row onto the balance widget's whale and it eats the row — the session directory goes to a recycle bin, not to rm. Deletion asks one short question first (how many tokens it burned, and that prompt can be turned off in Settings). Undo from the persistent toast or the 12-entry log in Settings. Clicking the whale jumps straight to the plugin's Settings, where you can swap the avatar, drag the mouth into place and rewrite all 17 UI strings; blank, currently-open and running sessions are refused in place with a reason.

Folds Think and tool-call rows into a floating summary pill with red failure counts, for a cleaner writer-friendly chat view.

Transactional uninstall engine: every destructive action runs validate/preview/execute/undo with Saga rollback, WAL crash recovery, hash-chain audit, hardlink dedup, and a Bayesian oracle that predicts success probability before you commit.

Task-scoped git worktrees for DSH: durable per-repo manifest, worktree mode injects a creation instruction with your first message under an automatic worktree/ branch prefix, header badge instead of workspace clutter, and bring-back or force-remove cleanup.

Git hygiene checker: read-only scan of merged and stale branches, oversized tracked files, untracked files and uncommitted work, with cleanup suggestions (it never deletes anything).

Per-task isolated git worktrees with a full create/sync/finish lifecycle: task names auto-derive branches, merge targets are double-checked, and batch cleanup is built in — zero manual git operations.

OpenAI-compatible image generation in DSH Desktop chat: generate inline, edit reference images or chain-edit previous results directly (image-to-image) without re-uploading, with storage cleanup.

Session install radar for DeepSeek Harness: lists what each conversation installed (pip, npm, git clones, winget-like installers) with size, path, creation time, purpose, why it was installed, and what removing it costs. Ships a sidebar panel, 10 agent tools, a timestamp sweep of temp directories, a process-command-line audit, and a two-step confirmed cleanup limited to temp directories. An optional scheduled cleanup of old temp directories is off by default.

Adds a Temporary tasks section above the workspace list, where one click creates a timestamped folder, workspace and session; tasks support search, sort, pin, rename and archive, can be moved into a regular workspace, and tasks that never receive a message are cleaned up automatically.

Registers a battle-tested development delivery rulebook as a skill family - one core skill (clarification, delivery checklist, navigation) plus nine focused skills (layered architecture, evidence-driven debugging, minimal changes, impact-graded verification, migration feature parity, async UI feedback, sizing rules, CLI safety and cleanup, project notes). Only the skills matching the current task are loaded, trivial tasks (small reversible single-file edits) are exempted outright, so each session pays tokens just for the rules it actually uses.

A deliberately context-free chat panel in the right sidebar: it sends only a one-line system prompt plus what you type there, with no tools, no session history and no fork of the current conversation, and keeps the panel history in memory. Each reply reports its own token usage, plus the cache hit rate on routes that return cache stats.

ComfyUI studio in a DSH sidebar panel: connects to a local or LAN ComfyUI server, picks saved image workflows, cleans and rewrites prompts, edits LoRAs and nodes, generates images, and previews results with copyable seeds.

Deletes the write-only streaming fragment rows from session logs on disk so a long session loads into fewer objects; the pruned log is checked against the loader contract before the file is replaced, and the previous file is kept as .orig.

A Windows disk cleaner for DeepSeek Harness that scans known-safe cache locations, shows their sizes, reclaims the space from a Web panel, and offers a read-only audit of what it cannot clean automatically.

Skill catalog with independent model and user manual invocation controls for file-backed Skills, live source reads, read-only non-file Providers, and safe cleanup of missing policies.

Send and receive QQ Agent Mail through an OAuth-authorized agently-cli account — six tools (send, list, read, search, reply, poll) that embed a session/thread marker in the subject, a background poller that routes inbound replies into the owning DSH Session and wakes it, and incoming HTML bodies rendered to clean markdown.

Cleanup Mode agent preset for DSH: read-only scans of leftovers (including duplicate detection), a manifest before anything is deleted, trash-first removal only after confirmation, and a per-session audit log. Cleaning outside the workspace requires a danger-full-access session; under workspace-write it can only inspect and will ask you to raise the permission.

Folder organization for the DeepSeek Harness sidebar: display-only Workspace folders (drag a Workspace onto a folder block to file it, nest and re-order folders, collapse with counts), durable per-Workspace nested Session folders, per-row icons chosen from 40 host icons or 48 emoji, and a Workspace-level "archive all sessions" cleanup. A fork of WSNMM3/dsh-session-keeper (MIT, itself derived from ht719/dsh-session-categories); it replaces the sidebar.workspaces region, so do not install it alongside the upstream plugins.

Adds a "Handoff session" item to the session context menu: pick an older session, choose how the new one should read it, and a fresh session is created with the handoff instruction pre-filled in its composer while the old session stays untouched. Three read modes — the AI decides what to read, a six-part summary written into a .md file, or just the last 20 turns. The second tab turns those .md files into a cleanup list grouped by workspace, deletable once the receiving session has run 3 turns or the handoff is 7 days old. All file, record and turn-count operations run in the host process; the browser half only renders and requests. Requires Windows and the DSH desktop app (it uses Electron shell.openPath and explorer.exe/cmd.exe).

A Storage settings page for DeepSeek Harness: a donut of what dsh occupies on this machine (install, sessions, attachments, runtimes, plugins, temp), a drill-down that lists archived sessions and can delete them, and a clean action that only touches rebuildable caches. Deleting to the system Recycle Bin and Open folder are Windows-only; scanning works everywhere. Host routes accept loopback connections only and are CSRF-guarded; nothing leaves the machine.

Session-header environment and branch chips: Local git-switches the checkout; Worktree creates an isolated git worktree under .agents/worktrees, registers it as a workspace, and offers merge, squash, delete, and auto-cleanup.

Checks installed plugins against a DSH update before you install it, and reports the shared UI members and host services they use that the new version no longer exports — the case where an update installs cleanly but leaves plugins failing to load. Includes a read-only diagnose command. Windows only, DSH desktop, Node.js 18+.
