axiomantic/.github

Default workflows and community files for repos under @axiomantic.

What's here

Reusable workflow: momus.yml

Centralized Momus AI PR-review configuration. Consumer repos call it with a thin stub:

# .github/workflows/momus.yml in any repo
name: Momus

on:
  pull_request:
    types: [opened, reopened, ready_for_review, synchronize]
  issue_comment:
    types: [created]
  workflow_dispatch:
    inputs:
      pr_number:
        description: PR number to review
        required: true
        type: string

jobs:
  call:
    permissions:
      contents: read
      pull-requests: write
      issues: write
    uses: axiomantic/.github/.github/workflows/momus.yml@devel
    with:
      pr_number: ${{ github.event.pull_request.number || github.event.issue.number || github.event.inputs.pr_number }}
      event_name: ${{ github.event_name }}
      trigger_command: /ai-review
      trigger_mention: "@axiomantic-momus[bot]"
    secrets:
      LLM_API_KEY: ${{ secrets.LLM_API_KEY }}
      MOMUS_APP_ID: ${{ secrets.MOMUS_APP_ID }}
      MOMUS_APP_PRIVATE_KEY: ${{ secrets.MOMUS_APP_PRIVATE_KEY }}

The consumer repo needs LLM_API_KEY set as a repository (or org) secret. MOMUS_APP_ID and MOMUS_APP_PRIVATE_KEY are optional — without them the bot falls back to the default GITHUB_TOKEN and any APPROVE verdict is downgraded to COMMENT (GitHub rejects approvals from github-actions[bot]). See axiomantic/momus SETUP.md for App setup.

Workflow template

workflow-templates/momus.yml makes the same workflow available in the GitHub "New workflow" UI for any new repo under @axiomantic.

Defaults

• Provider: OpenRouter (https://openrouter.ai/api/v1)
• Model: deepseek/deepseek-v4-pro
• Trigger: /ai-review slash command and @axiomantic-momus[bot] mention

Override per repo via with: in the stub:

    with:
      model: anthropic/claude-sonnet-4-6
      base_url: https://api.anthropic.com/v1
      trigger_command: /review

Per-repo behavior also tunable via .momus.yaml at the repo root — see config-defaults.yaml.
