 ### Added
 
+- every command that takes a team now accepts its key, name, or UUID, resolved through one shared lookup: `team states`, `team members`, `team delete`, `label list/create/delete --team`, `cycle list/view --team`, `project list/create/update --team`, `document list/create/update --team`, and `issue query/mine/create/update --team`. Keys stay canonical and win over a same-spelled name; an unknown team errors with the list of valid keys instead of an empty result or a raw API error. Previously only keys worked, which is why [#276](https://github.com/schpet/linear-cli/issues/276) asked for `team list --json` as a name-to-key lookup
+- `issue query --state` and `issue mine --state` accept a workflow state name or ID as well as the six state types, looked up within the queried team scope (all teams under `--all-teams`, where a name matches every team's same-named state). An unknown name errors and lists the scope's states, and types and names can be mixed
 - `project update --content <markdown>` and `--content-file <path>` replace a project's long-form overview body, matching the flags `project create` already had. Previously the only way to change the body after creation was a hand-written `projectUpdate` mutation through `linear api`
 - `--json` (`-j`) on `team list`, `cycle list`, `cycle view`, `milestone list`, `milestone view`, and `project view`, the last read commands without machine-readable output. List commands emit the same `{ nodes, pageInfo }` connection shape as the other list commands, after the same filtering and ordering as the table; view commands emit the GraphQL object as fetched, including every issue rather than the ten-item preview, and `milestone view --all --json` includes every page. (A 2.0.0 entry claimed `cycle list --json`; that change never actually landed.) ([#276](https://github.com/schpet/linear-cli/issues/276); thanks @lakardion)
