Build the proton-drive Hermes skill following the Phase 4 spec
from ARCHITECTURE.md (§5). Primary path: rclone protondrive backend
with Drive SDK as a fallback option.
Skill components:
- skills/proton-drive/SKILL.md — YAML frontmatter + full docs for
all 9 tools (list, read, download, upload, search, mkdir,
delete, stat, sync) with usage, error handling, security notes
- skills/proton-drive/__init__.py — package init with exports
- skills/proton-drive/tools.py — Python subprocess wrappers for
each tool, plus rclone availability/remote checks
- tests/test_drive.py — 25 unit tests (all pass) with mocked
subprocess.run
All 9 Proton Drive tools implemented:
proton_drive_list, proton_drive_read, proton_drive_download,
proton_drive_upload, proton_drive_search, proton_drive_mkdir,
proton_drive_delete, proton_drive_stat, proton_drive_sync

Proton Drive Skill
Agents can read, write, search, and manage files on Proton Drive through the battle-tested rclone protondrive backend.
Prerequisites
1. Install rclone
# Linux (official script)
curl https://rclone.org/install.sh | sudo bash
# macOS
brew install rclone
# Verify
rclone version
2. Configure the protondrive remote
rclone config create protondrive protondrive \
username=your@proton.me \
password=your_password \
--non-interactive
Or interactively:
rclone config
# → Choose "n" (new remote)
# → Name: protondrive
# → Type: protondrive
# → Follow prompts for username, password, 2FA
3. Set environment variables (optional)
export PROTON_RCLONE_REMOTE=protondrive # default: protondrive
export PROTON_RCLONE_PATH=/path/to/rclone # default: auto-detect from PATH
On first run, rclone will prompt for the mailbox password (your Proton login password). After authentication, tokens are cached locally by rclone's own credential store — no additional auth management needed for subsequent calls.
Tools
The skill provides 9 tools for interacting with Proton Drive. Each tool
shells out to rclone with the configured protondrive remote.
proton_drive_list
List files and folders in a path on Proton Drive.
Usage: rclone lsf --json <remote>:<path>
Args:
path (string, default: "/") — Path to list (e.g. "Documents" or "/")
recursive (bool, default: false) — List recursively
dirs_only (bool, default: false) — Show directories only
files_only (bool, default: false) — Show files only
Returns: JSON array of {Name, Path, Size, ModTime, IsDir} items
proton_drive_read
Read a file's content from Proton Drive.
Usage: rclone cat <remote>:<path>
Args:
path (string, required) — Path to the file (e.g. "Documents/notes.txt")
head (int, optional) — Only read first N lines
tail (int, optional) — Only read last N lines
Returns: File content as text string (up to 10MB; larger files use download instead)
Large files (>10MB) should be downloaded rather than read inline. The
tool will return an error suggesting proton_drive_download for files
exceeding the size threshold.
proton_drive_download
Download a file from Proton Drive to a local path.
Usage: rclone copy <remote>:<path> <local_path>
Args:
remote_path (string, required) — Source path on Drive (e.g. "Documents/report.pdf")
local_path (string, required) — Destination local path (absolute or ~/expanded)
progress (bool, default: false) — Show transfer progress
Returns: JSON with {status, local_path, size_bytes}
The local path must be writable. If the path ends with /, the file
is downloaded into that directory preserving its filename.
proton_drive_upload
Upload a local file or directory to Proton Drive.
Usage: rclone copy <local_path> <remote>:<path>
Args:
local_path (string, required) — Source path on local filesystem
remote_path (string, required) — Destination path on Drive (e.g. "Documents/")
create_parents (bool, default: true) — Create parent dirs if they don't exist
progress (bool, default: false) — Show transfer progress
Returns: JSON with {status, remote_path, size_bytes}
Supports both individual files and entire directories.
proton_drive_search
Search for files by name across Proton Drive.
Usage: rclone lsf -R --files-only <remote>: | grep -i <query>
OR (for structured results): rclone lsf -R --json <remote>: | jq <filter>
Args:
query (string, required) — Search term or regex pattern
path (string, default: "/") — Root path to search under
regex (bool, default: false) — Treat query as regex instead of substring
max_results (int, default: 50) — Max results to return
Returns: JSON array of matching {Name, Path, Size, ModTime}
proton_drive_mkdir
Create a folder on Proton Drive.
Usage: rclone mkdir <remote>:<path>
Args:
path (string, required) — Path of folder to create (e.g. "Documents/NewFolder")
Returns: JSON with {status: "created", path}
Creates all parent directories if they don't exist (like mkdir -p).
proton_drive_delete
Delete a file or empty folder from Proton Drive.
Usage: rclone delete <remote>:<path>
Args:
path (string, required) — Path to the file/folder to delete
recursive (bool, default: false) — Recursively delete folder contents
Returns: JSON with {status: "deleted", path}
Non-recursive deletion of non-empty folders will fail. rclone's
purge command is used for recursive deletes.
proton_drive_stat
Get detailed metadata for a file or folder.
Usage: rclone lsl <remote>:<path>
OR (detailed): rclone lsf --json <remote>:<path>
Args:
path (string, required) — Path to the file or folder
Returns: JSON with {Name, Path, Size, ModTime, IsDir, Hash, MimeType}
proton_drive_sync
Synchronize a local directory with Proton Drive (or vice versa).
Usage: rclone sync <source> <destination> [flags]
Args:
source (string, required) — Source path (local: or remote:)
dest (string, required) — Destination (local: or remote:)
direction (enum, default: "upload") — "upload" (local→Drive), "download" (Drive→local), "bidirectional"
dry_run (bool, default: true) — If true, show what would change without syncing
delete_excluded (bool, default: false) — Delete files at dest not present at source
Returns: JSON with {status, changed, added, deleted, errors}
IMPORTANT: Defaults to dry_run=true for safety. The agent MUST
confirm with the user before running a live sync, especially when
delete_excluded=true — this can cause data loss.
Implementation
All tools are implemented as Python subprocess wrappers in the
tools/ subdirectory. The primary backend is rclone; the
TypeScript Drive SDK is available as a fallback via
PROTON_DRIVE_USE_SDK=true.
Tool Handler Pattern
def handle_proton_drive_list(args: dict, **kwargs) -> dict:
path = args.get("path", "/")
recursive = args.get("recursive", False)
cmd = _build_rclone_command("lsf", "--json", path, recursive=recursive)
result = _run_rclone(cmd, timeout=30)
if result.returncode != 0:
return {"error": result.stderr.strip()}
items = [json.loads(line) for line in result.stdout.strip().split("\n") if line]
return {"items": items}
Rclone Configuration Check
Before any tool execution, verify the rclone remote exists:
def _check_rclone_remote(remote: str) -> bool:
result = subprocess.run(
["rclone", "listremotes"],
capture_output=True, text=True, timeout=5
)
return f"{remote}:" in result.stdout
If the remote is not configured, return a clear error with setup instructions referencing the README.
Error Handling
| Error | Cause | Resolution |
|---|---|---|
remote not found |
protondrive remote not configured | Run rclone config or refer to README |
authentication required |
Token expired or invalid | Run rclone config reconnect <remote> |
file not found |
Path doesn't exist | Check path with proton_drive_list |
file too large |
Read attempt on >10MB file | Use proton_drive_download instead |
rate limited |
Too many API calls | Retry with backoff (rclone does this auto) |
Security Notes
- Files read by
proton_drive_readenter the agent's context. For sensitive documents, preferproton_drive_downloadand specify a local path. proton_drive_syncwithdelete_excluded=trueis destructive. Always default todry_run=trueand require confirmation.- rclone stores tokens in its config file
(
~/.config/rclone/rclone.conf). Ensure this file has appropriate file permissions (chmod 600).
