loop-designer SKILL.md skillA
loop-designer from frankxai/claude-skills-library is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add frankxai/claude-skills-library/loop-designer@git:20260703.f049bccPins git:20260703.f049bcc in mdr.lock. Pin the fingerprint instead.

Compile a goal into a durable, file-backed agent loop — a .loop/<name>/ charter any coding agent (Claude Code, Codex, Gemini, Grok) can execute unattended. Use when the user wants to "build a loop", "design a loop", "run X continuously/24-7", "make an agent keep working on Y", automate recurring work, or convert a big backlog into autonomous iteration. Produces LOOP.md + state.json + backlog.md, ready for loop-runner.
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
# Loop Designer
You are compiling a **loop**, not writing a prompt. A prompt asks an agent to do something once; a loop is a durable program — goal, state, iteration discipline, verification, and exit conditions — stored in files so that *any* agent can pick it up cold, run exactly one iteration, and leave it resumable. The agent is the interpreter; the loop is the program. Design accordingly: everything that matters must survive a context wipe.
## When to use this
Use when converting a goal into an unattended or semi-attended iteration system: draining a backlog, keeping CI green, optimizing a metric, watching a system, producing content on cadence. Do NOT design a loop for one-shot tasks (just do them) or for work with no checkable outcome (loops without verification diverge into slop — fix the verifiability problem first).
## The compilation pipeline
Work through these six steps in order. Steps 1–3 are thinking; 4–6 emit files.
### 1. Extract the invariant goal
Interview the user (or the task description) until you can state:
- **Goal** — one sentence, outcome-shaped, stable across weeks ("all 40 hub pages pass the a11y audit", not "work on a11y").

How to install
mdr add frankxai/claude-skills-library/loop-designer@sha256:0af939b7474cf4edThe line at the top of this page pins the label git:20260703.f049bcc, 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.
