octo-matter

octo-matter is a skill for Claude Code, Codex from Mininglamp-OSS/octo-cli. It costs 39 tokens per session (1,539 once invoked), scanned A, original, Apache-2.0.

A task-management interface for Matter, Octo's name for a todo or work item. It covers creating, finding, updating, assigning, scheduling, and tracking these items.

In plain words
What is it for?
Use it to create and manage tasks, change their status, assign people, filter or search them, connect them to conversations, and extract tasks from chat messages.
Why use it?
It removes the need to manage work items through separate manual commands or systems. It also keeps assignees, status, source channels, deadlines, reminders, and history connected to each item.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

octo-matter scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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>

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
