skelm — 本番投入できる agentic workflows

scripts から durable agents まで、ひとつの authoring model。

workflow は型付き TypeScript モジュールです。決定的な code、model inference、agent loops を直接使い、schedules、webhooks、queues、durable state が必要になったら同じ workflow を gateway 経由で host します。

実際の workflow を end to end で

現在の examples からの incident response: 並列の deterministic triage の後、tools、MCP、filesystem、network の明示的 permissions を持つ agent step を実行します。

import { agent, code, parallel, pipeline } from 'skelm'
import { z } from 'zod'

export default pipeline({
  id: 'incident-response',
  input: z.object({
    incidentId: z.string(),
    service: z.string(),
    description: z.string(),
  }),
  output: z.object({
    rootCause: z.string(),
    immediateActions: z.array(z.string()),
  }),
  triggers: [{ kind: 'webhook', path: '/webhooks/incident' }],
  steps: [
    parallel({
      id: 'triage',
      steps: [
        code({ id: 'search-issues', run: () => ({ issues: [] }) }),
        code({ id: 'open-channel', run: () => ({ channel: 'inc-001' }) }),
      ],
    }),
    agent({
      id: 'root-cause',
      backend: 'opencode',
      prompt: (ctx) => `Analyze this incident:\n${ctx.input.description}`,
      permissions: {
        allowedTools: ['gh.search_issues', 'slack.post_message'],
        allowedMcpServers: ['github'],
        allowedExecutables: [],
        fsRead: [],
        fsWrite: [],
        networkEgress: { allowHosts: ['api.github.com', 'slack.com'] },
      },
      output: z.object({
        rootCause: z.string(),
        immediateActions: z.array(z.string()),
      }),
      maxTurns: 4,
    }),
  ],
})
