Seafile Skill
Overview
Use this skill to interact with one Seafile library through the repo-token API. It is designed for three tasks only:
- Search for files or folders by filename or path fragment inside the token's library scope
- Download a file by exact Seafile path
- Upload a local file into an existing Seafile directory
This skill does not cover full-text content search, cross-library discovery, deletes, renames, moves, or share-link management.
For endpoint details, see references/seafile-api.md. For reusable shell patterns, see references/command-patterns.md.
Prerequisites
Required:
curljq- Network access to the Seafile server
SEAFILE_BASE_URLSEAFILE_REPO_TOKENwith access to the target library
Optional with defaults:
SEAFILE_LIBRARY_ROOT, which defaults to/SEAFILE_OUTPUT_DIR, which is only needed when saving downloaded files locally
Export the required variables before running commands. The optional variables below are shown with their recommended defaults:
export SEAFILE_BASE_URL="https://seafile.example.com"
export SEAFILE_REPO_TOKEN="<repo-token>"
export SEAFILE_LIBRARY_ROOT="/" # optional
export SEAFILE_OUTPUT_DIR="$PWD/downloads" # optional, used for downloads
mkdir -p "$SEAFILE_OUTPUT_DIR"
Defaults and expectations:
SEAFILE_BASE_URLshould be the server origin without a trailing slashSEAFILE_LIBRARY_ROOTdefaults to/if you do not override itSEAFILE_OUTPUT_DIRis only needed for downloads- All Seafile paths in this skill are absolute library paths such as
/,/docs, or/docs/report.pdf
Authentication
The repo-token endpoints use the repo token in the Authorization header.
Use this default form unless your deployment documents a different token scheme:
AUTH_HEADER="Authorization: Token $SEAFILE_REPO_TOKEN"
API_BASE="${SEAFILE_BASE_URL%/}/api/v2.1/via-repo-token"
Before doing search, download, or upload, verify the token and library scope:
curl --fail --silent --show-error \
-H "$AUTH_HEADER" \
"$API_BASE/repo-info/" | jq
If this fails with 401 or 403, stop and fix the token, permissions, or server URL before continuing.
Search Workflow
Use repo-token directory listing and filter locally with jq. This is filename and path search, not full-text search.
1. List items from a starting path
START_PATH="${SEAFILE_LIBRARY_ROOT:-/}"
curl --fail --silent --show-error \
-G \
-H "$AUTH_HEADER" \
--data-urlencode "path=$START_PATH" \
--data-urlencode "recursive=1" \
"$API_BASE/dir/"
Useful query parameters:
path: directory to inspect, default/recursive=1: walk the subtree recursivelytype=f: files onlytype=d: directories only
2. Filter by filename fragment
NEEDLE="report"
START_PATH="${SEAFILE_LIBRARY_ROOT:-/}"
curl --fail --silent --show-error \
-G \
-H "$AUTH_HEADER" \
--data-urlencode "path=$START_PATH" \
--data-urlencode "recursive=1" \
"$API_BASE/dir/" |
jq -r --arg needle "$NEEDLE" '
.dirent_list[]
| select((.name // "") | ascii_downcase | contains($needle | ascii_downcase))
| [.type, .parent_dir, .name]
| @tsv
'
3. Filter by full path fragment
PATH_FRAGMENT="2026/q2"
START_PATH="${SEAFILE_LIBRARY_ROOT:-/}"
curl --fail --silent --show-error \
-G \
-H "$AUTH_HEADER" \
--data-urlencode "path=$START_PATH" \
--data-urlencode "recursive=1" \
"$API_BASE/dir/" |
jq -r --arg needle "$PATH_FRAGMENT" '
.dirent_list[]
| (.parent_dir + "/" + .name | gsub("//+"; "/")) as $full_path
| select($full_path | ascii_downcase | contains($needle | ascii_downcase))
| [$full_path, .type]
| @tsv
'
When you need exact metadata for one known file path, consult the repo-token file-info section in references/seafile-api.md and confirm the route shape against the target deployment if needed.
Download Workflow
Downloads are exact-path only.
SEAFILE_OUTPUT_DIR is optional overall and only matters if you want this skill to save the downloaded file to a local directory.
1. Request a one-time download link
REMOTE_FILE="/docs/report.pdf"
DOWNLOAD_LINK=$(curl --fail --silent --show-error \
-G \
-H "$AUTH_HEADER" \
--data-urlencode "path=$REMOTE_FILE" \
"$API_BASE/download-link/" |
jq -r '.')
2. Download the file to a local path
LOCAL_FILE="$SEAFILE_OUTPUT_DIR/$(basename "$REMOTE_FILE")"
curl --fail --silent --show-error --location \
"$DOWNLOAD_LINK" \
-o "$LOCAL_FILE"
Notes:
download-link/returns a URL string, not a JSON object- Use
--locationbecause the returned URL may redirect - Keep the remote path exact, including spaces, case, and file extension
Upload Workflow
Uploads send a local file into an existing Seafile directory.
1. Request an upload link
UPLOAD_LINK=$(curl --fail --silent --show-error \
-H "$AUTH_HEADER" \
"$API_BASE/upload-link/" |
jq -r '.')
2. Upload one local file
LOCAL_FILE="./artifact.zip"
TARGET_DIR="/incoming"
curl --fail --silent --show-error \
-F "file=@${LOCAL_FILE}" \
-F "parent_dir=${TARGET_DIR}" \
-F "replace=0" \
"${UPLOAD_LINK}?ret-json=1" |
jq
Upload behavior:
parent_dirmust be an absolute library path like/incomingreplace=1overwrites an existing file with the same namereplace=0preserves the existing file and lets Seafile rename the new upload if needed?ret-json=1returns structured JSON and should be used by default
If you need Seafile to create nested folders beneath an existing parent, add -F "relative_path=subdir1/subdir2/" to the upload request.
Error Handling
Check failures in this order:
401or403The token is missing, expired, malformed, or does not allow the requested action.404The base URL or endpoint is wrong, or the server is not exposing that API path.440or similar upload validation errors The filename is invalid for the target server.442or443The file is too large or the library is out of quota.- Directory listing or download returns no match Re-check the starting directory, exact remote path, and case sensitivity.
- Upload succeeds but lands in the wrong place
Re-check
parent_dirand anyrelative_pathvalue.
When a request is failing and the server output is unclear, remove --silent temporarily and inspect headers with curl -i.
Examples
Find files matching a name fragment
NEEDLE="invoice"
START_PATH="/finance"
curl --fail --silent --show-error \
-G \
-H "Authorization: Token $SEAFILE_REPO_TOKEN" \
--data-urlencode "path=$START_PATH" \
--data-urlencode "recursive=1" \
--data-urlencode "type=f" \
"${SEAFILE_BASE_URL%/}/api/v2.1/via-repo-token/dir/" |
jq -r --arg needle "$NEEDLE" '
.dirent_list[]
| select((.name // "") | ascii_downcase | contains($needle | ascii_downcase))
| (.parent_dir + "/" + .name | gsub("//+"; "/"))
'
Download one file by exact path
REMOTE_FILE="/finance/invoices/april-2026.pdf"
DOWNLOAD_LINK=$(curl --fail --silent --show-error \
-G \
-H "Authorization: Token $SEAFILE_REPO_TOKEN" \
--data-urlencode "path=$REMOTE_FILE" \
"${SEAFILE_BASE_URL%/}/api/v2.1/via-repo-token/download-link/" |
jq -r '.')
curl --fail --silent --show-error --location \
"$DOWNLOAD_LINK" \
-o "$SEAFILE_OUTPUT_DIR/april-2026.pdf"
Upload one local file into a target folder
TARGET_DIR="/incoming/reports"
LOCAL_FILE="./build/report.csv"
UPLOAD_LINK=$(curl --fail --silent --show-error \
-H "Authorization: Token $SEAFILE_REPO_TOKEN" \
"${SEAFILE_BASE_URL%/}/api/v2.1/via-repo-token/upload-link/" |
jq -r '.')
curl --fail --silent --show-error \
-F "file=@${LOCAL_FILE}" \
-F "parent_dir=${TARGET_DIR}" \
-F "replace=1" \
"${UPLOAD_LINK}?ret-json=1" |
