split-architecture SKILL.md skillA
split-architecture from etr/groundwork is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add etr/groundwork/split-architecture@git:20260622.e142476Pins git:20260622.e142476 in mdr.lock. Pin the fingerprint instead.

This skill should be used when converting a single-file architecture doc to directory-based format for better organization of large architecture documents.
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
# Split Architecture Skill
Converts a single-file architecture document (`{{specs_dir}}/architecture.md`) into a directory-based format (`{{specs_dir}}/architecture/`) for better organization and targeted context loading.
## When to Use
- **Automatically** by `design-architecture` and `source-architecture-from-code` when the single-file architecture doc crosses **500 lines** or **10 decision records** (sections matching `### DR-\d+`)
- **Manually** when the user invokes `/split-architecture`
## Step 0: Resolve Project Context
1. **Monorepo check:** Does `.groundwork.yml` exist at the repo root?
- If yes → Is `{{project_name}}` non-empty?
- If empty → Invoke `Skill(skill="groundwork:select-project")` to select a project, then restart this skill.
- If set → Project is `{{project_name}}`, specs at `{{specs_dir}}/`.
- If no → Continue (single-project repo).
2. Proceed with the resolved project context.
## Step 1: Validate Preconditions
1. **Check single file exists:** `{{specs_dir}}/architecture.md` must exist
- If missing → output "No single-file architecture doc found at `{{specs_dir}}/architecture.md`. Nothing to split." and stop.
…Read the whole file at its exact version.
How to install
mdr add etr/groundwork/split-architecture@sha256:9cb34fbb9b9609b2The line at the top of this page pins the label git:20260622.e142476, 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.
