dsh-session-artifacts

This package is built by DeepSeek-v4.1 flash!

English · 中文

Clean up what a session left in your workspace — and, when you want it, delete the session record too. Opt-in, previewed, and verified before anything is removed.

A session's scripts, reports and generated files stay behind after the conversation is gone. Nothing in DSH records which files those were, so this plugin reconstructs that from the session log and shows you the exact list — with the total size — before anything is deleted.

Three things it can do, chosen by two checkboxes in one dialog:

Delete the artifacts, keep the conversation — tidy up a session's mess without losing the session.
Delete the session record — with or without its artifacts.
Neither is assumed: the artifact step is off by default.

It is self-contained: it removes the session record itself and does not call dsh-chat-manager's /plugins/dsh-session-delete route, so it keeps working when that plugin is disabled or absent.

What it does

Open the session's ⋯ menu and pick Delete session and artifacts…
The dialog shows the exact file list and total size before you commit.
Tick what you want removed. At least one box must be ticked.
Confirm. When the record is being removed it goes first, then the previewed files.
If a file could not be removed, the dialog offers Retry the files left behind — it retries exactly those paths, not the whole preview.

The artifacts-only mode needs no session deletion at all: the Host holds the previewed list behind a nonce, so the files are removable while the session and its log stay exactly where they are.

Deleting the session record

The persistence seam deliberately has no deletion API — its own contract states that logs accumulate under the session root until removed externally. So this plugin performs the removal itself, against the fixed layout:

<sessionRoot>/<project>/<sessionId>/session[.vN].jsonl[.zstd]

The location is resolved through the persistence backend (resolveCurrentLog), then every component is re-checked before anything is touched:

exactly three segments under the root, with a session-log leaf name;
each directory is a real directory and the log a real file — no symlinks;
nothing resolves outside the root;
removal is a two-step quarantine: the directory is renamed into a sibling temp directory, its identity is re-verified there, and only then deleted. A failure part-way restores the original rather than leaving it half-deleted.

Stopping a session that is open

An open session is live in the host registries even when nothing is running in it, so its log writer is still attached and its row would reappear in the sidebar. It has to be torn down before its storage can go — and the registry exposes no dispose.

The only supported teardown is the AgentHandle returned to whoever created the Agent, so this plugin keeps its own handle tracker: it observes Agent creation on the shared agents service and retains each handle. Deletion then:

cancels a running turn (the same path the Stop button uses);
disposes the Agent through its handle — this is what unregisters it and detaches its Session;
waits for both registries to drain, then removes the storage.

The tracker is this plugin's own rather than another plugin's, so the capability does not go away when that plugin does.

One case cannot be handled: an Agent that was already live before the plugin loaded has no captured handle (the handle was only ever given to its creator). That deletion is refused with a message telling you to restart DSH — after a restart the plugin sees every Agent from the start. It is refused rather than deleted underneath its writer, because reporting a deletion that did not happen is worse than not deleting.

How a file is attributed to a session

The durable session log is the only authoritative record of what a session touched, so attribution is read from it:

Evidence	Meaning	Deletable
`write` result with `meta.operation: "create"`	the session materialized the file	yes
shell command window + file creation time	the file was created while a command ran	yes, if unique
`present` call	the session delivered the file	no (reported only)
`write` result with `meta.operation: "update"`	the session rewrote a file that already existed	no
`edit` call	the session only rewrote an existing file	no

Rewriting a file you already owned never makes it disposable, so update and edit results are reported but never offered. A failed tool call (FS_SANDBOX_DENIED, FS_NOT_OBSERVED, FS_STALE_VERSION, …) contributes nothing, because the tool never materialized anything.

present is delivery, not authorship: a session asked to hand you a paper you already had would otherwise make that paper deletable. Delivered-only files are counted in the dialog and left alone. Set includeDelivered: true to opt into the older, more aggressive behavior.

Shell-created files

File-tool writes are recorded explicitly. Shell commands are not: a pwsh call records only its command text, and its tool/result carries no meta at all, so nothing durable names the files a python foo.py run produced. In practice this is the dominant source of leftovers — a session that writes twenty scripts through the shell produces twenty artifacts that a file-tool-only reader never sees.

The remaining evidence is creation time. On NTFS birthtime is a real creation timestamp, distinct from mtime, and it survives later edits — so it answers "was this file created while this command was running?". Pairing each shell tool/call with its tool/result gives a tight window per command.

Three rules keep this safe:

Tight windows. Only the interval a command actually ran counts. A whole-session window is unusable: a session that ran two commands and then spent twenty minutes browsing would otherwise claim every file created during its lifetime. (Measured on a real log: such a session had 90 files inside its session-wide span and 0 inside its actual command windows.)
Uniqueness. A file created inside two sessions' windows is attributed to neither, because a wrong attribution deletes something this session never made. Concurrent sessions therefore reduce the result instead of corrupting it.
Fail closed. If the sibling sessions cannot be enumerated, the pass claims nothing and says so in the dialog. "Only my window covers it" cannot be established without knowing the others.

Only creation is claimed. A file that merely changed during a window was not produced by the session and is left alone. Inferred files are labelled 命令行 / shell in the list, since they rest on weaker evidence than a recorded write.

Safety

Workspace fence. A session may only ever propose files inside its own recorded working directory.
DSH home fence. Nothing under ~/.dsh is ever an artifact, whatever the session's working directory is. The workspace fence alone is relative to cwd, so a session opened at ~ or C:\ could otherwise reach the installed plugins, the built skills, the profiles, and the credential store. A genuine workspace nested inside the home (e.g. ~/.dsh/scratch) still owns its own files, but cannot reach its neighbours.
Package fence. A file inside a directory that is a DSH package — it holds SKILL.md, cordis.patch.yml, cordis.yml, or a package.json with a dsh/cordis block — is not offered, so a plugin or skill the session built inside its own workspace survives. Set protectPackages: false to disable.
Symlinks. A candidate whose real path escapes the workspace through a symlink is skipped, both at preview and at removal time.
No stale deletions. Every file is re-checked immediately before it is unlinked; a file whose size or identity changed since the preview is skipped rather than removed.
Relative paths resolve against the session's cwd, never the Host process working directory, so report.md means the file the session actually wrote.
The client never names paths. The Host holds the previewed set behind a single-use, 10-minute nonce. A path the user was never shown cannot be deleted, and a nonce cannot be replayed.
Retry is pinned. A retry entry re-baselines the file's size (the preview size is stale by definition) but pins its device + file index, so a path swapped for a different file between the two passes is refused.
Directories are never deleted as artifacts. Only regular files are offered; directories the deletion empties are pruned, stopping at the workspace root.
No secure erasure. Removal is an ordinary unlink. Backups, cloud copies, snapshots, and filesystem-level recovery are outside its scope.

Configuration

All fields are optional; the defaults are the safe ones.

Field	Default	Meaning
`dshHome`	derived	Overrides the DSH home used by the home fence. Otherwise `DSH_HOME`, otherwise the parent of a `<home>/sessions` store.
`extraExcludes`	`[]`	Extra absolute paths that must never be offered.
`protectPackages`	`true`	Refuse files inside a DSH plugin/skill package.
`includeDelivered`	`false`	Also offer files the session merely delivered.
`includeShell`	`true`	Run the shell creation-window pass.
`shellSlackMs`	`5000`	Slack around a command window, absorbing the gap between the event clock and the filesystem clock.
`deleteSession`	`true`	Whether the Host offers session-record deletion. `false` makes the plugin artifacts-only: the record checkbox is hidden and the flow never touches the log.
`lifecycleTimeoutMs`	`20000`	How long to wait for a stopped session to leave the live registries.

Requirements

The per-session JSONL session-persistence backend (sessionPersistence), which every shipped composition mounts.
The live Agent registry (agents), provided by @deepseek-ai/dsh-agent. It is a declared dependency, because the handle tracker must be installed before any Agent is created — a tracker installed later captures nothing.
DSH core 0.2.x for the session-menu and overlay slots it extends.

No other plugin is required. sessions is used when present, to stop a running turn before teardown.

Limitations

Shell attribution relies on birthtime. On a filesystem that does not record a true creation time, the shell pass finds nothing rather than guessing.
Only the creating session is detected. A file one session created and another later edited stays attributed to the creator.
A session that creates a file through a long-running background job started near the end of its window may fall outside the window. Prefer the file tools for anything you expect to delete later.
Directories are never offered, so a session that only created directories (and nothing inside them) leaves them behind.
The preview is a snapshot. Files created after it are not included.
Subagent sessions record their own writes; deleting a parent does not automatically delete a child's artifacts.
A session that was already open before this plugin loaded cannot be torn down (no handle was captured), so its record cannot be deleted until DSH is restarted. Deleting its artifacts still works.
The handle tracker observes the shared agents service, so it only sees Agents created through it. A composition that creates Agents some other way behaves like the pre-existing case above.

Install

dsh plugin --profile <profile> add dsh-session-artifacts

Or from a checkout:

dsh plugin --profile <profile> add <path-to-this-directory>

Then restart DSH for the Host and client halves to compose.

Uninstall

dsh plugin --profile <profile> remove dsh-session-artifacts

Uninstalling removes only this plugin. It never deletes sessions or artifacts on its own.

Tests

npm test

The suites cover attribution rules, the shell creation-window pass (including the fail-closed path and the two-session ambiguity rule), the workspace / DSH home / package fences, cross-drive paths, symlink escapes, identity re-verification, relative-path resolution, empty-directory pruning, nonce single-use, the retry nonce, the request fence, and the real apply() wiring end to end.
