Commands

You drive @Sigilix the way you’d ask a teammate: @mention it and say what you want. A bare question gets a grounded answer; a verb like review or open a PR triggers an action. There’s nothing to memorize and no rigid syntax — the phrasings below are the canonical forms, and @Sigilix understands natural variations of them.

Every command runs inside your workspace’s scope and draws on the earned-context layer, so answers and artifacts are grounded in your actual codebase and its review history. See How it answers for the flow each one follows.

At a glance

@Sigilix <question>

Ask anything about the codebase. @Sigilix retrieves from the index, code graph, and review memory, then answers anchored to concrete evidence — file:line, the merged PRs that set a pattern, and the ADRs behind a decision. It won’t assert what it can’t ground.

@dana   @Sigilix where do we validate that an order total matches its line items?

@Sigilix  In `orders/validate.ts:58` — `assertTotalsMatch(order)` sums
          `lineItems[].amount` and compares against `order.total`, throwing
          `TotalsMismatchError` on drift. It's called from the order
          create/update path in `orders/service.ts:114` and `:139`. The
          "validate totals server-side, never trust the client" rule is
          ADR-0014, introduced in #488.

It keeps explaining in-thread until the team is aligned — follow up with “what calls that?” or “what breaks if I change it?” and it narrows further, pulling more context each turn rather than restarting.

@Sigilix review <PR or branch>

Run the full ensemble on demand. The four specialists — Logic & Architecture, Security, Performance, Tests — run in parallel, unified by the synthesizer, exactly as on an automatic review. See The Ensemble.

The verdict and inline findings post to GitHub; a summary posts back to the Slack channel so the thread stays informed without leaving Slack.

@Sigilix summarize <PR>

A fast read on where a PR stands: an effort estimate, which believability gates the findings passed, the files ranked by risk, and the synthesizer’s verdict. Useful before a merge decision or a standup.

@Sigilix file issue

Turn the thread into a triaged Linear or Jira ticket. @Sigilix rewrites the title to be searchable, assigns a priority/severity, names a likely owner from code ownership and history, and links the relevant files and PRs. This is the issue-triage pipeline reachable from Slack.
