forked from molecule-ai/molecule-core
Replaces the proposed monolithic molecule-guardrails plugin with 12
single-purpose plugins users can install à la carte. Powered by a
small extension to the AgentskillsAdaptor base class so any plugin can
ship hooks/, commands/, and a settings-fragment.json without writing a
custom adapter.
## Base adapter changes
workspace-template/plugins_registry/builtins.py + sdk/python/molecule_plugin/builtins.py
(both copies — drift-tested):
- New _install_claude_layer() helper called at the end of install()
- Conditionally copies hooks/ → /configs/.claude/hooks/ (preserving exec bit)
- Conditionally copies commands/*.md → /configs/.claude/commands/
- Conditionally merges settings-fragment.json into /configs/.claude/settings.json
with ${CLAUDE_DIR} placeholder rewritten to the workspace's absolute install
path. Existing user hooks are preserved (deep-merge by event name).
- All steps no-op when the plugin doesn't ship the corresponding files,
so existing skill+rule plugins (molecule-dev, superpowers, ecc,
browser-automation) are unchanged.
Drift test (tests/test_plugins_builtins_drift.py) still passes.
## 12 new plugins
Hook plugins (ambient enforcement):
- molecule-careful-bash — refuses destructive bash; ships careful-mode skill
- molecule-freeze-scope — locks edits via .claude/freeze
- molecule-audit-trail — appends every Edit/Write to audit.jsonl
- molecule-session-context — auto-loads cron-learnings at session start
- molecule-prompt-watchdog — injects warnings on destructive prompt keywords
Skill plugins (on-demand):
- molecule-skill-code-review — 16-criteria multi-axis review
- molecule-skill-cross-vendor-review — adversarial second-model review
- molecule-skill-llm-judge — deliverable-vs-request scoring
- molecule-skill-update-docs — post-merge doc sync
- molecule-skill-cron-learnings — operational-memory JSONL format
Workflow plugins (slash commands):
- molecule-workflow-triage — /triage full PR-triage cycle
- molecule-workflow-retro — /retro + cron-retro skill, weekly retrospective
Each ships only what it needs — most have just plugin.yaml + skills/ or
hooks/ + adapter (one-line stub: `from plugins_registry.builtins import
AgentskillsAdaptor as Adaptor`). Total ~120 files but each plugin is
small and self-contained.
## Verification
- python3 -m molecule_plugin validate plugins/molecule-* → all 13 valid
(12 new + pre-existing molecule-dev)
- End-to-end install smoke test on representative samples: hook plugin
(molecule-careful-bash), skill-only plugin (molecule-skill-code-review),
workflow plugin (molecule-workflow-triage). All produce expected
/configs/ tree, settings.json paths rewritten, exec bits preserved,
zero warnings.
- workspace-template pytest tests/test_plugins_builtins_drift.py → passes
(SDK + runtime stay in sync).
## CLAUDE.md repo-doc updated
Lists all 12 new plugins under the existing Plugins section, organized
by category (hook / skill / workflow). Each entry one line, recommend-
together hints where dependencies make sense.
