- 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 write-as.sh
|
|
# @description Server mode, one Linux user per account (S3): installed as
|
|
# /opt/agenthub/libexec/write-as. The dashboard runs it AS a member through
|
|
# sudo (`sudo -n -u ah-<name> /opt/agenthub/libexec/write-as <path> [mode]`)
|
|
# for every change it makes inside that member's home — the file editor, a
|
|
# `.gitignore` line, the files a pane reads (prompt, proxy settings, context
|
|
# copies, drops, a session's launch file) — because the dashboard itself may
|
|
# never write, chmod or delete there: the member can swap any name in their
|
|
# own home, and a write by another account would follow the swap. As the
|
|
# member this can only do what the member could. Content comes on stdin,
|
|
# never in argv (sudo logs argv). Modes:
|
|
# (none) stdin into the file in place (keeps its mode and owner)
|
|
# append stdin appended
|
|
# replace stdin into a new 0644 file renamed over the path (atomic)
|
|
# private same, 0600
|
|
# mkdir the directory, 0755, parents included
|
|
# remove the path, recursively (rm never follows a symlink it removes)
|
|
# move the path to the 3rd argument (rename; never onto an existing
|
|
# name — checked just before, and the dashboard checks first)
|
|
# copy the path, recursively, to the 3rd argument (symlinks copied as
|
|
# links, never followed; mode and times kept; never onto an
|
|
# existing name)
|
|
# extract a tar on stdin unpacked into the directory (the dashboard's
|
|
# batch upload, a tar it wrote itself: folders and regular files
|
|
# only); an existing file is never replaced (`-k` fails instead)
