- Chat: an Agent step shows its task, status and tool calls and opens its conversation in place; Windows paths (E:\…, C:/…) in replies open as files - Prompt: attach a file on this computer by path (native picker), clearer too-large messages - Artifacts: edit title/description and a skill's files (new snapshot), Reinstall, install history, Hub-only rows, skills installed into ~/.claude/skills and ~/.agents/skills - Files: batch upload of small files in one extract - AI Tools: npm install falls back to --prefix ~/.local when the global prefix is not writable

/**
|
||
* @file artifacts.js
|
||
* @description The Artifacts hub (docs/plans/artifacts/README.md): what agents
|
||
* produce, kept per OWNER and — in server mode — shared to every user.
|
||
*
|
||
* Four kinds:
|
||
* - `page` a claude.ai Artifact a session published: only a link, accepted
|
||
* only as `https://claude.ai/…`. Captured from the `Artifact`
|
||
* tool's PostToolUse hook (`captureFromHook`) or pasted by hand.
|
||
* - `file` a file an agent wrote in a workspace, pinned by the user.
|
||
* - `skill` a Claude Code skill folder (the user's own, or a workspace's
|
||
* `.claude/skills/<name>`).
|
||
* - `plugin` a plugin by `name@marketplace` and its marketplace source; no
|
||
* files.
|
||
*
|
||
* Rules:
|
||
* - A `file` or `skill` is a SNAPSHOT taken when it is added, written under
|
||
* `<data dir>/artifacts/<snapshot>/` and never touched again. Every read a
|
||
* viewer makes is of that copy — no route reads another user's home for
|
||
* them — and a path from a request only ever picks one of the snapshot's
|
||
* own recorded files (`snapshotFile`).
|
||
* - Visibility: in local mode every row; in server mode a developer sees
|
||
* their own rows plus shared ones, admin and analyst see every row (like
|
||
* sessions), and only the owner (or an admin) changes or deletes one.
|
||
* - Installing a shared skill or plugin is the viewer's click, into the
|
||
* VIEWER's own accounts only (`installAccounts`): a member's home under S3
|
||
* (written AS them through `write-as`, `claude` run as them through sudo),
|
||
* plus the host's home for an admin (their host-folder workspaces run as
|
||
* the host), or the host alone in local mode. A skill goes into BOTH
|
||
* `~/.claude/skills/` and the cross-tool `~/.agents/skills/` of each, so
|
||
* every AI tool and every session of the viewer finds it. An existing skill
|
||
* is never overwritten without `replace`, and the old one is moved aside to
|
||
* `~/.claude/agenthub-replaced-skills/`, never deleted. A plugin is
|
||
* installed without `-y`, so one whose marketplace declares an install
|
||
* command fails rather than runs unseen. An admin can turn installs off
|
||
* for everyone (`setInstallsEnabled`). Share, unshare and install are
|
||
* written to `audit_log`.
|
||
* - Editing a skill's name, description or instructions (`editSkill`) writes
|
||
* a NEW snapshot and swaps the row to it; the old snapshot is dropped, and
|
||
* copies already installed stay as they were (Reinstall picks it up).
