P6 Phase 1: enforce the workspace-template contract via CI on every
template-repo push, eliminating the slow drift that produced 8
copies of a 28-line Dockerfile in different states of decay.
The previous validator (50 lines, soft warnings only) couldn't
catch the cache-trap pattern (Dockerfile missing ARG RUNTIME_VERSION)
that silently shipped the previous runtime wheel during cascade
publishes — observed five times in a row on 2026-04-27. Hardened
into structural checks that fail CI, not just warn:
- Dockerfile must base on python:3.11-slim
- Dockerfile must declare ARG RUNTIME_VERSION AND reference
${RUNTIME_VERSION} in a RUN block (the arg has to be in the
layer's command line for docker to hash it into the cache key)
- Dockerfile must create the agent uid-1000 user (Claude Code
refuses --dangerously-skip-permissions as root for safety)
- Dockerfile must end at molecule-runtime — directly via
ENTRYPOINT or via a wrapper script that exec's it (claude-code
has entrypoint.sh for gosu drop-priv; hermes has start.sh to
boot the hermes-agent daemon first; both are allowed)
- config.yaml must have name + runtime + integer
template_schema_version. Quoted "1" fails — observed previously
in a copy-pasted template that the YAML loader turned into str
- requirements.txt must declare molecule-ai-workspace-runtime
Also fixed: the original validator's warning telling adapter.py
NOT to import molecule_runtime was backwards — that's the
canonical package name post-#87. Now it warns on the legacy
molecule_ai prefix instead.
Reusable workflow change: instead of running
.molecule-ci/scripts/validate-workspace-template.py (a per-template
vendored copy that drifts as the validator evolves), the workflow
now checks out molecule-ci itself into .molecule-ci-canonical and
runs the canonical script from there. Single source of truth —
every template runs the SAME contract on every CI run. The legacy
.molecule-ci/scripts/ directories in each template repo can be
deleted in a Phase 2 cleanup PR.
14 unit tests pin the contract:
- canonical template passes
- claude-code-style custom entrypoint passes when the wrapper
exec's molecule-runtime
- 5 Dockerfile drift modes each error individually
- 3 config.yaml drift modes each error/warn
- requirements.txt missing-runtime errors
- legacy molecule_ai import warns
- regression cover: modern molecule_runtime import does NOT
trigger the (deleted) backwards warning
All 8 production template repos pass the new contract today —
this PR locks in the current good state, it does not force any
template-repo edits.
Contract documented at docs/template-contract.md so the rules are
discoverable without reading the validator.

molecule-ci
Shared CI workflows for the Molecule AI ecosystem. Every plugin, workspace template, and org template repo calls these reusable workflows to enforce a standard validation gate.
Usage
Plugin repos (molecule-ai-plugin-*)
# .github/workflows/ci.yml
name: CI
on: [push, pull_request]
jobs:
validate:
uses: Molecule-AI/molecule-ci/.github/workflows/validate-plugin.yml@main
Workspace template repos (molecule-ai-workspace-template-*)
# .github/workflows/ci.yml
name: CI
on: [push, pull_request]
jobs:
validate:
uses: Molecule-AI/molecule-ci/.github/workflows/validate-workspace-template.yml@main
Org template repos (molecule-ai-org-template-*)
# .github/workflows/ci.yml
name: CI
on: [push, pull_request]
jobs:
validate:
uses: Molecule-AI/molecule-ci/.github/workflows/validate-org-template.yml@main
Any repo with auto-merge enabled
PR-time guards (currently: disable auto-merge on follow-up push). Consume from a thin caller:
# .github/workflows/pr-guards.yml
name: pr-guards
on:
pull_request:
types: [synchronize]
permissions:
pull-requests: write
jobs:
disable-auto-merge-on-push:
uses: Molecule-AI/molecule-ci/.github/workflows/disable-auto-merge-on-push.yml@main
When the team lands more PR-time guards in this repo, add them as additional jobs in the same caller — keeps each consuming repo's footprint to one file.

disable-auto-merge-on-push
PR-time safety guard. When pull_request:synchronize fires (= a new commit pushed to an open PR) and auto-merge is already enabled, this workflow disables auto-merge and posts a comment requiring the operator to re-engage explicitly.
Why it exists: on 2026-04-27, molecule-core PR #2174 auto-merged with only its first commit because the second commit was pushed AFTER the merge queue had locked the PR's SHA. The second commit ended up orphaned on a merged-and-deleted branch.
Pairs with the org-wide repo setting "Automatically delete head branches" (already enabled on all 10 Molecule-AI repos). Defense in depth:
- Repo setting blocks pushes to a merged-and-deleted branch (catches the post-merge orphan case).
- This workflow catches the in-queue race (push during queue processing) by force-disabling auto-merge.
Together they cover the full lifecycle of "auto-merge enabled → new commits arrive" without operator discipline.
False-positive note: if a CI bot pushes (dependency update, secret rotation), this also disables auto-merge. That's intentional — the operator who originally enabled auto-merge gets notified and re-engages, which is exactly the verify-after-machine-edits behavior we want.
