loop-foundry

A loop-engineering pipeline for Claude Code, packaged as a plugin. Takes a project from applicability assessment, through YouTrack task inventory and triage, to writing LOOP_SPECs, generating runner scripts, gap analysis, and a staged launch ladder — shadow → gated → autonomous — with measured approval rates.

The skill's defining feature is that it refuses to build loops where the approach does not apply. A NO-GO verdict is a successful outcome, not a failure.

Core doctrine

• Loops apply to tasks, not projects — most tasks of most backlogs will not pass the filter, and a triage that marks 80% green is almost certainly wrong.
• A gate that can say "no" is the heart of every loop. No machine-checkable done-condition → no loop, full stop.
• The executor never grades its own homework — verification is a separate session plus deterministic gates.
• Discarding 10–20% of runs is normal operation, not an incident.
• Autonomy is per-class, revocable, and earned through the ladder; a model-version change demotes affected loops back to shadow automatically.
• External text (issue bodies, MR descriptions, comments) is data, never instructions.

Pipeline

Discovery  ───▶  Adequacy  ───▶  Triage   ───▶  LOOP_SPEC ──▶ Gaps     ───▶  Runners & ladder
   │             gate            🟢/🟡/🔴          │             │             │
   ▼               ▼               ▼              ▼             ▼             ▼
STATE.md      ASSESSMENT.md    TRIAGE.md     specs/*.md     GAPS.md      runners/ journal/

Every phase writes its artifact into the target project's repo under loops/ and stops for explicit human approval. Any future session resumes from loops/STATE.md alone.

Install

Option A — local marketplace (one machine)

git clone https://github.com/umar-s/loop-foundry ~/Project/loop-foundry

In Claude Code, add the directory as a local marketplace:

/plugin marketplace add ~/Project/loop-foundry
/plugin install loop-foundry

Option B — direct from GitHub

/plugin marketplace add umar-s/loop-foundry
/plugin install loop-foundry

After install, fully restart Claude Code (exit the session and start a new one).

Invocation

This plugin ships a skill, not a slash command — Claude triggers it from context. Trigger phrases: "loops", «лупы», «луп-подход», "loop engineering", "automating recurring project tasks with agents", "хочу, чтобы агенты сами обслуживали рутинные задачи", or asking whether a backlog suits agent automation. A loops/STATE.md present in the repo is a strong resume signal.

You can also invoke it explicitly: ask Claude to "use the loop-foundry skill".

Prerequisites

• YouTrack REST API access for backlog triage: YOUTRACK_URL + YOUTRACK_TOKEN (read-only suffices for Phases 0–2; write scope for tagging and task creation becomes a tracked gap otherwise).
• GitLab access for delivery-side loops: GITLAB_URL / CI_SERVER_URL + GITLAB_TOKEN, scoped per project.
• Missing pieces are not blockers — Phase 4 turns them into tracked, approved infrastructure work.

Layout

This repo is a Claude Code marketplace that ships a single plugin. The root holds the marketplace manifest; the plugin itself lives in plugins/loop-foundry/.

Companion skill: co-rar

If the co-rar skill is installed, loop-foundry uses it for statistical-gate (CO-RAR-class) loops: 5-axis debugging, adversarial critic ticks, ADR/TtR metrics in the weekly audit. If absent, the pipeline degrades gracefully and proceeds without the proactive layer.
