example-layered-skill SKILL.md skillA
example-layered-skill from dcc-mcp/dcc-mcp-core is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add dcc-mcp/dcc-mcp-core/example-layered-skill@git:20260927.f5cfb64Pins git:20260927.f5cfb64 in mdr.lock. Pin the fingerprint instead.

Example skill — reference implementation of the **internal** layered architecture pattern (Tools / Services / Utils) for complex skills with shared business logic. Use as a template when a skill outgrows a single scripts/execute.py file. Not intended for production use — see docs/guide/skills.md for the architectural guide.
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
# Layered Skill Architecture — Reference
This skill demonstrates the **internal** layered organisation recommended for
complex skills (see [`docs/guide/skills.md`](../../../docs/guide/skills.md)
section "Complex Skill Architecture").
It is intentionally simple — three asset-management tools that share a small
service object — so the **structure**, not the business logic, is the focus.

How to install
mdr add dcc-mcp/dcc-mcp-core/example-layered-skill@sha256:a62c73699a4a4f84The line at the top of this page pins the label git:20260927.f5cfb64, 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.
