slice SKILL.md skillA
slice from thoughtbot/rails-consultant is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add thoughtbot/rails-consultant/slice@git:20261106.7724c75Pins git:20261106.7724c75 in mdr.lock. Pin the fingerprint instead.

Cut a feature or idea down to one full-stack slice.
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
# Full-stack slice SPEC
A full-stack slice cuts vertically through every layer a feature needs: storage, logic, interface, integration. It ships on its own, and a user gets something they couldn't get before. The opposite is a horizontal slice ("add the schema", "build the API", "design the UI"), which ships nothing anyone can use and hides the integration pain until the end.
Full stack means whatever this project's fullest stack is. For a web app, storage through to screen. For a CLI, argument parsing through to printed output. Let the repo tell you its layers instead of assuming.
The job is finding the version that costs a fraction of the work and is still worth shipping. The SPEC goes to a session that has none of this conversation, so it has to stand alone.
## Workflow
Arguments start with `--auto`? Nobody will answer. Read [Autonomous mode](#autonomous-mode) first; it replaces the interview and both gates below.
1. Capture the raw idea in the user's words.
2. Recon the codebase with subagents. Wait for them; the interview depends on what they find.
3. Run the interview to cut scope.

How to install
mdr add thoughtbot/rails-consultant/slice@sha256:af15c4fb76bedab6The line at the top of this page pins the label git:20261106.7724c75, 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.
