Autonomous Loops — Patterns for Agent Automation

⚠️ Security & Consent — READ FIRST

This skill teaches unattended repository automation. It can create branches, open pull requests, retry CI failures, and merge code without a human in the loop. That power is dangerous in the wrong hands and on the wrong target.

Before using any pattern in this skill, you MUST:

1. Get explicit, informed consent from the repository owner. "I want to automate PRs" is not consent for "merge my production code at 3 AM without review."
2. Default to dry-run. All patterns below start in --disable-commits / no-write mode. Only flip the switch when you understand what each flag does.
3. Use protected branches + least-privileged credentials. The GitHub token this loop uses must not have admin/org-owner scopes. A scoped fine-grained PAT scoped to one repo is the minimum.
4. Set hard limits. Every loop must have --max-runs, --max-cost, and --max-duration. Without these, a runaway loop will burn budget or destroy state.
5. Never loop on production. Run on a fork, a scratch repo, or a clearly-labeled branch. The main branch should be merged by a human.
6. Audit your inputs. Specs, directory listings, and captured diffs may contain secrets, customer data, internal paths, or proprietary code. Never pipe those into an external agent command without scrubbing them first.

Patterns in this skill that touch the network, filesystem, or git remotes will refuse to run unless the corresponding safety flags are explicitly set. If a pattern silently merges or pushes, that is a bug — file an issue.

See references/security-checklist.md for the full audit before first use.

Running agents in loops enables spec-driven development, CI/CD-style pipelines, and iterative refinement without human intervention between steps. Used correctly, this is a productivity multiplier. Used carelessly, it can drain a bank account, leak secrets, or rewrite a production codebase.

Quick Start

Choose your pattern by complexity:

1. Sequential Pipeline (simple) — Chain claude -p calls for linear workflows
2. Persistent REPL (simple) — Interactive sessions with history
3. Spec-Driven Parallel (medium) — Deploy N agents from spec, manage waves
4. PR Automation Loop (medium) — PR creation, CI fix, auto-merge
5. De-Sloppify Pass (add-on) — Cleanup step after any implementation
6. RFC-Driven DAG (advanced) — Multi-unit parallel work with dependency graph

Pattern Spectrum

Pattern	Setup	Complexity	Default Mode	Best For
Sequential Pipeline	Bash script	Low	Dry-run	Daily tasks, scripted workflows
REPL	Node/CLI	Low	Read-only	Interactive development
Parallel Agents	Agent loop	Medium	Dry-run	Content generation, spec variations
PR Loop	Shell script	Medium	--disable-commits	Iterative multi-day projects
De-Sloppify	Add-on to any	Optional	Dry-run	Quality cleanup after implementation
DAG Orchestration	Python/Node	High	Dry-run	Large features, parallel units, merge coordination

Key Principles

1. Isolation — Each loop iteration gets fresh context (no bleed-through)
2. Context Persistence — Use files (SHARED_TASK_NOTES.md) to bridge iterations
3. Exit Conditions — Always set max-runs, max-cost, max-duration, or completion signal
4. No Blind Retries — Capture error context for next iteration (and redact secrets first)
5. Separate Concerns — Different loop patterns for different problem sizes
6. Default Deny — Network writes, git pushes, and merges require explicit opt-in flags

Decision Matrix

Is this a single focused change?
├─ Yes → Sequential Pipeline
└─ No → Do you have a spec/RFC?
         ├─ Yes → Do you need parallel work?
         │        ├─ Yes → DAG Orchestration
         │        └─ No → PR Automation Loop
         └─ No → Do you need many variations?
                  ├─ Yes → Parallel Agents + Spec
                  └─ No → Sequential Pipeline + De-Sloppify

Anti-Patterns

❌ Infinite loops without exit conditions ❌ No context bridge between iterations ❌ Retrying the same failure without capturing error context ❌ Negative instructions instead of cleanup passes ❌ All agents in one context window (reviewer should never be the author) ❌ Ignoring file overlap in parallel work ❌ Auto-merge without explicit human approval on every merge ❌ Skipping the security checklist before first use
