Synchronize architecture document with codebase changes. Usage /groundwork:source-architecture-from-code.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Sync Architecture Skill
Keeps `{{specs_dir}}/architecture.md` synchronized with actual implementation decisions.
## Pre-flight: Model Recommendation
**Your current effort level is `{{effort_level}}`.**
Skip this step silently if effort is `high`, `xhigh`, or `max` (the scale is `low` < `medium` < `high` < `xhigh` < `max`, so `xhigh` and `max` are already above `high`) AND you are Sonnet or Opus.
If effort is `low` or `medium` (i.e. below `high`), you MUST show the recommendation prompt — regardless of model.
If you are not Sonnet or Opus, you MUST show the recommendation prompt - regardless of effort level.
Otherwise → use `AskUserQuestion`:
```json
{
"questions": [{
"question": "Do you want to switch? Architecture impact analysis from session changes benefits from consistent reasoning.\n\nTo switch: cancel, run `/effort high` (and `/model sonnet` if on Haiku), then re-invoke this skill.",
"header": "Recommended: Sonnet or Opus at high effort",
"options": [
{ "label": "Continue" },
{ "label": "Cancel — I'll switch first" }
],
"multiSelect": false
}]
}
```

How to install
mdr add etr/groundwork/source-architecture-from-code@sha256:5a3681e2ebf179a3The line at the top of this page pins the label git:20260624.e533827, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
