Octo Files

octo-files — file I/O and bot housekeeping

Two small domains are covered here because they share a base URL ($OCTO_API_BASE_URL/v1/bot/*) and are usually needed together:

• file — 4 ops, no bot-kind restrictions
• bot — 6 ops, no bot-kind restrictions

1. File operations

octo-cli file upload      --file ./report.pdf [--type chat] [--path subdir/]
octo-cli file download    <path> --format json > saved.bin      # <path> = storage key (no bucket prefix), see note below
octo-cli file credentials --filename report.pdf
octo-cli file presigned   --filename report.pdf --fileSize 1048576   # --fileSize (bytes) is REQUIRED

upload — multipart form

Unlike every other command, file upload sends a multipart multipart/form-data body, not JSON. The --file flag is required and names a local path; --type (default chat) and --path become form text fields. Promoted body flags declared in the spec go in as text fields alongside the binary.

The response envelope carries the returned file descriptor under data — use it to build attachment references in message send.

download — returns a presigned URL

file download <path> issues a GET. The backend responds with a 302 redirect to the storage tier. The CLI does not stream raw bytes — instead it returns a JSON envelope containing the presigned URL:

octo-cli file download /chat/2026/05/abc123.png
# → {"ok":true,"data":{"url":"https://s3.../abc123.png?...","status":302,"content_type":"image/png"}}

To actually fetch the file, use the URL from the response:

octo-cli file download /chat/2026/05/abc123.png --jq '.data.url' | xargs curl -o out.png

Direct-to-S3 uploads

For files too large for multipart, ask the backend for a presigned target and upload directly:

size=$(stat -f%z big.zip 2>/dev/null || stat -c%s big.zip)    # fileSize in bytes (REQUIRED; no padding)
cred=$(octo-cli file presigned --filename big.zip --fileSize "$size")
url=$(jq   -r '.data.uploadUrl'                   <<<"$cred")
ctype=$(jq -r '.data.contentType'                 <<<"$cred")
cdisp=$(jq -r '.data.contentDisposition // empty' <<<"$cred")
curl -X PUT -T big.zip -H "Content-Type: $ctype" ${cdisp:+-H "Content-Disposition: $cdisp"} "$url"

file presigned requires --fileSize (bytes) — the size is signed into the PUT Content-Length, so a missing/oversized value is rejected (HTTP 400 — fileSize is required). It returns {method, uploadUrl, downloadUrl, contentType, key, expiresIn, expiredTime, maxFileSize, [contentDisposition]} — a one-shot signed URL (echo contentDisposition verbatim on the PUT if present). file credentials returns STS-style temporary credentials ({bucket, region, key, credentials:{tmpSecretId, tmpSecretKey, sessionToken}, startTime, expiredTime, cdnBaseUrl}) for SDK-driven uploads. Pick the shape the backend gives you.

2. Bot housekeeping

octo-cli bot register       [--data '{"agent_platform":"…","agent_version":"…","plugin_version":"…"}']
octo-cli bot set-commands   --data '{"commands":[{"command":"fix","description":"create a matter"}]}'
octo-cli bot user-info      --uid <uid>         # --uid is REQUIRED; returns {uid,name,avatar} for that user
octo-cli bot space-members  [--keyword <q>]     # members of the bot's space (limit cap 200)
octo-cli bot typing         --channel-id <cid> --channel-type 1 [--on-behalf-of <uid>]
octo-cli bot heartbeat

bot register — special auth

register is the only operation not behind the authBot middleware. The backend routes it by token prefix: app_* → registerAppBot, bf_* → registerUserBot. You still supply OCTO_BOT_TOKEN; the CLI treats the call like any other.

Use bot register exactly once per bot lifecycle (publish), then use bot set-commands to advertise slash-command metadata.

Get the owner_uid from bot register

bot user-info needs --uid and returns only {uid, name, avatar} — it does not carry owner_uid. The bot's owner_uid comes from the one-time bot register at publish; capture it then and cache it (env/config) rather than re-registering:

owner=$(octo-cli bot register --jq '.data.owner_uid')   # capture once at publish, then cache

This is the value LLM-backed operations require as creator_uid (e.g. the withheld matter extract, once the matter domain is re-enabled).

typing and heartbeat

Both are fire-and-forget. typing signals an "…is typing" UI state in DM channels. heartbeat refreshes bot liveness — call it on a long-running poll loop so the platform knows the bot is alive.

3. Common pattern: message attachment end-to-end

# 1. Upload the binary.
up=$(octo-cli file upload --file ./log.txt --type chat)
url=$(jq -r '.data.url'  <<<"$up")
name=$(jq -r '.data.name' <<<"$up")

# 2. Attach it to a message.
octo-cli message send --data "$(jq -n \
  --arg c "chat-1" --arg u "$url" --arg n "$name" \
  '{chat_id:$c, text:"see log", attachments:[{url:$u, name:$n, type:"text/plain"}]}')"

4. Error recovery

5. Schema lookup

octo-cli schema file.upload
octo-cli schema file.download
octo-cli schema bot.register
octo-cli schema bot.user-info
