Octo Matter

octo-matter — the matters domain

A matter is the Octo equivalent of a task or todo. The domain has 17 operations across five groups: core CRUD, status transitions, assignees, channels, and timeline. Plus one LLM helper: matter extract.

Backend: matters service at $OCTO_API_BASE_URL/api/v1/matters. Both App Bot and User Bot can call every operation in this domain.

1. Core CRUD

octo-cli matter create --title "Fix login bug"                     # required: --title (≤500 chars)
octo-cli matter list   --status open --assignee-id me --limit 50   # cursor pagination
octo-cli matter get    <id>
octo-cli matter update <id> --title "..." --description "..."
octo-cli matter delete <id>                                        # soft delete

create also accepts --description (≤10 000), --assignee-ids (repeatable — supports me alias), --deadline (RFC3339), --remind-at (RFC3339), --source-channel-id, --source-channel-type (1=user, 2=group, 5=thread), --source-name.

list filters: --status, --assignee-id (me supported), --creator-id, --q <query>, --source-channel-id, --source-channel-type, --channel-id, --limit (default 20, max 100), --cursor.

2. Status transitions

There is no state machine — any status can move to any status.

octo-cli matter transition <id> --status done
octo-cli matter close      <id>          # alias → --status done
octo-cli matter reopen     <id>          # alias → --status open
octo-cli matter archive    <id>          # alias → --status archived

Valid values: open, done, archived.

3. Assignees

octo-cli matter assignee add    <id> --user-id <uid>
octo-cli matter assignee remove <id> <uid>

--user-id accepts me to self-assign. Adding a user who is already assigned returns DUPLICATE_ASSIGNEE (validation error — recover by listing current assignees first).

4. Channels

Link a matter to a chat channel so conversations show up in context.

octo-cli matter channel link   <id> --channel-id <cid> --channel-type 1   # 1=user 2=group 5=thread
octo-cli matter channel link   <id> --channel-id <cid> --channel-type 2 --channel-name "#eng-ops"
octo-cli matter channel unlink <id> <channel_id>

5. Timeline

Timeline entries are the successor to comments. Simple text goes through --content; attachments, quoted messages, and channel context go through --data:

octo-cli matter timeline add    <id> --content "Ping from oncall"
octo-cli matter timeline add    <id> --data '{
  "content":"see attached log",
  "attachments":[{"url":"https://…/log.txt","name":"log.txt","type":"text/plain"}]
}'
octo-cli matter timeline list   <id>                           # paginated
octo-cli matter timeline delete <id> <entry_id>

--content caps at 10 000 characters.

6. AI extract — create a matter from chat messages

matter extract hands a chat transcript to an LLM and returns a structured matter. Typical bot use:

octo-cli matter extract --data '{
  "channel_type": 2,
  "channel_id":   "ch_abc",
  "creator_uid":  "<bot-owner-uid>",
  "msgs": [
    {"uid":"u_alice","text":"we need to fix login"},
    {"uid":"u_bob","text":"+1 by friday"}
  ]
}'

Critical: a bot must set creator_uid to its owner_uid, not its own bot_uid — the backend rejects the request otherwise. Capture owner_uid from the one-time octo-cli bot register response at publish (--jq '.data.owner_uid') and cache it (env/config); reuse the cached value rather than re-registering on every extract. Note bot user-info does not return it (it needs --uid and returns only {uid,name,avatar}).

7. Common patterns

Self-scope with me

Anywhere an assignee UID is accepted, me resolves server-side to the caller's UID.

octo-cli matter list --assignee-id me --status open

Cursor pagination

All list endpoints follow {data:[], pagination:{has_more, next_cursor}}. Let the CLI walk them:

octo-cli matter list --status open --page-all
octo-cli matter timeline list <id> --page-all --page-limit 5

Pipe chains

octo-cli matter list --status open --assignee-id me --jq '.data[].id' \
  | xargs -I{} octo-cli matter close {}

8. Error recovery

9. Schema lookup

When unsure about a flag or body shape:

octo-cli schema matter.create
octo-cli schema matter.list
octo-cli schema matter.timeline.add

Everything in this skill is derived from those specs — if the schema says otherwise, trust the schema.
