Works with

src/jobs/pr-joke.ts
import { createJob, TerseAgent } from "terse-sdk"
// generated from your workspace
import {
  Triggers,
  Skills,
  GitHubRepo,
  SlackChannel,
} from "./terse.generated"
 
createJob({
  name: "pr-joke",
  // typed triggers
  triggers: [Triggers.github.onPullRequest({ repo: GitHubRepo.Terse })],
  onTrigger: async () => {
    const agent = TerseAgent.create({
      // scoped to channels you grant
      skills: [Skills.slack({ channel: SlackChannel.AllTerseInc })],

/terse:create Add a workflow that summarizes related PRs and DMs the assignee in Slack when a Linear issue lands in Triage.

Let me check what Linear events look like.

Read 6 sample events from Triggers.linear.onIssueCreated

Writing the workflow.

Wrote linear-triage.ts (28 lines)

Testing against the 6 sample events.

6/6 passed in 1.1s.

Deploying.

Deployed in 8.2s. Triggers active at deal-desk-linear-triage.terse.run.

Try "/terse:create …"

/terse:improve The Slack DMs aren't reaching everyone in last week's runs.

Pulling recent runs to find the failures.

Read 50 runs from linear-triage. 12 failed at slack.sendMessage.

Some assignees don't have a slackUserId. Adding a fallback to post in the team channel with the assignee's name.

Modified linear-triage.ts (+12 −4)

Replaying the 12 failed runs.

11/12 now pass. 1 still failing: the team channel is archived.

Shipping the fix.

Deployed in 2.1s. Replaying live events from the failed window.

Why Terse

Equipped to build production workflows.

Typed end-to-end

Mistakes caught at compile time, not in prod.

Your editor knows which channels, repos, and projects Terse has access to. Reference one you haven't granted, and the type checker catches it before the workflow ever runs.

src/jobs/release-alert.ts
const agent = TerseAgent.create({
  skills: [Skills.slack({ channel: SlackChannel.Engineering })],
⚠Engineering channel either does not exist, or Terse does not have access. Add @Terse to the channel to grant access.
})

Improves with use

Production teaches the workflow.

Every week, Terse reviews recent runs and proposes patches: missing fallbacks, prompt drift, redundant calls. Apply with terse apply, verify with terse test.

Deterministic by default

Skip the agent when you don't need one.

Not every step needs reasoning. Call skill methods directly with the toolbox: same typed SDK, same ACL'd scopes, no agent overhead. Use it when you just need to push, pull, or post.

src/jobs/deploy-notify.ts
import { toolbox, SlackChannel } from "./terse.generated"
 
// no agent needed for deterministic calls
await toolbox.slack.sendMessage({
  channelId: SlackChannel.Releases.channelId,
  message: "Deployed v2.4.1",
})

Debug like code

Reproduce any run locally.

terse history lists past runs. terse replay reproduces any one locally with the exact event. terse test runs jobs locally against sample events. terse listen pipes live prod events into your dev process.
