For teams whose developers live in Jira Cloud or Linear.

Your setup

Say this to Certyn

In the web chat, once:

Connect Linear so the team can mention @Certyn on issues.

Then on an issue:

@Certyn the fix is on staging. Retest the linked bug and tell me what the last run found.

Setup, once:

Linear: opens the Linear connect form. Connect Linear workspace adds Certyn as an app user, bound to the chat's project and environment. A Linear workspace admin must do it.
Jira Cloud: a Jira site admin installs the Certyn app, then opens Apps → Certyn → Connect to Certyn and approves the site in Certyn with a project and environment. An Atlassian org admin creates a free service account named Certyn (Directory → Service accounts). People mention that account. It needs no token and no Jira seat.

On the issue:

In Jira, Certyn replies looking into this, then edits that reply into the answer. In Linear, a mention or delegating the issue to Certyn opens an agent session, and the answer shows in the thread.
Certyn finds the Certyn issue linked to the ticket. It can:
- say what runs found, the last retest and its result, and which tests cover it;
- start a retest or a run, after asking (answer with another mention);
- search issues and test cases, and read the wiki.
Each ticket keeps one conversation, so a later mention keeps the context.

No forms or approval prompts there. Secrets, sign-ins, connections, variables, environments, schedules and other settings are refused. Do them in the web chat.
No Machine there. Certyn starts a run and links it; mention it again later for the result.
A retest needs a confirmed Certyn issue linked to the ticket or to a test case.
One Certyn project and environment per Jira site or Linear workspace.
Jira Cloud only. The Jira app is installed from a link the Certyn team sends you; ask support for it.
