Attack a design until it holds

A critic hammers the design and a builder answers — every objection tracked, and none closed without evidence.

prompt
→ Claude
Before committing to an architecture, interface, or rollout plan, have a critic argue that it is wrong. Record each objection, impact, and status in a repository-local log at .agent-reviews/redteam.md. The builder must fix and verify each high-impact weakness or document why it is accepted; the critic may reopen unsupported answers. Stop when no high-impact objection remains or the same issues repeat for two rounds without new evidence. Finish with the decision, resolved and accepted objections, evidence, and any stalemate.

Promote prompts only on holdout wins

Test challenger prompts on a working set, promote only on fresh holdout wins, and keep the champion when results are uncertain.

prompt
→ Claude
Improve a prompt, policy, or configuration. A support assistant's system prompt is one example. Save the champion, its score, a working set, untouched holdout cases, must-pass checks, and [budget]. Each round, change one thing based on a recorded failure. Promote the challenger only if it beats the champion on holdouts by [margin] without weakening a must-pass check; otherwise keep the champion. Stop at the target, budget limit, or no progress. Return the winner, scores, experiment log, and remaining failures.

Rebuild a page pixel-for-pixel

Capture a real page, build a static mirror and a live version, then repair the weakest fidelity signals until they match.

prompt
→ Claude
Point War Loops at an authorized URL or image. Capture it with a genuine browser and record the layout, styles, content, motion, and responsive behavior. Build a static Pencil mirror and a moving Forge version. Compare both with the source at desktop, tablet, and mobile sizes; repair only the weakest fidelity signals. Stop when every gate passes, progress stalls, or capture is blocked. Finish with the builds, spec, renders, scores, and remaining gaps.

Verify agent output before it ships

Run one agent in an isolated worktree and release its staged output only after a second agent verifies the work.

prompt
→ Claude
Use Loop Harness for scheduled repository work such as CI triage, issue grooming, dependency updates, or docs sync. Set [retry limit], then start an isolated git worktree. Let one Claude session stage a patch or outbox message and a second Claude session verify it against explicit criteria. Ship only after a pass; otherwise preserve the findings and retry only within the limit. Finish with the source revision, staged output, verifier result, delivery status, and next run.

Claude ships, Codex reviews

Open a PR, run an independent Codex review, fix every blocking finding, and repeat until it's clean.

prompt
→ Claude
Run /clodex [task] think hard --max-iter 5 --threshold medium. Claude plans the task, implements it, opens a pull request, asks Codex for an adversarial review, fixes findings above the accepted severity, and repeats. Keep the branch, PR, findings, verdict, and iteration state resumable. Stop when Codex approves, only accepted findings remain, progress stalls, or the iteration cap is reached. Never describe an errored or exhausted run as approved. Finish with the PR, checks, verdict, and remaining findings.

Turn product changes into a podcast

Each cycle, turn meaningful public product changes into a short, source-grounded podcast episode.

prompt
→ Claude
Each night, review publicly released product changes and select only those users need to know. Verify each against the product, docs, or release notes. Use the Jellypod MCP to turn the approved changes into a three-to-five-minute podcast explaining what changed, why it matters, and how to try it. Check the script and audio for accuracy, clarity, and pronunciation. If nothing meaningful shipped, make no episode. Ask before publishing. Finish with the draft episode, sources, and review result.

Take a ticket to reviewer-ready

Turn a ticket or bug report into a proven root cause, a minimal patch, and a clean handoff a reviewer can trust.

prompt
→ Claude
Take a ticket, bug report, failing behavior, or customer complaint and turn it into a review-ready patch. Reproduce the failure in the smallest representative environment, prove the root cause, make the smallest credible fix, and rerun the original reproduction plus relevant regression tests. If the issue cannot be reproduced after two serious attempts, say so. Do not fold unrelated refactors into the patch. Finish with the cause, changed files, before-and-after proof, risks, and pull-request summary.

Clean production data to spec

Remove disallowed records, sharpen the classification logic, and verify the remaining dataset against an explicit definition.

prompt
→ Claude
Review production records, remove anything that does not meet the allowed definition, improve the classification logic, and verify the remaining data.

Evaluate the whole product to a bar

Run realistic scenarios across every major capability, fix weak outcomes, and rerun until each clears the defined bar.

prompt
→ Claude
Build sanitized, production-scale local data under production-like settings. Inventory every user-facing feature, role, route, button, input, modal, state, and workflow; define documented acceptance criteria and finite risk-based edge cases for each. Test as a real user, logging every bug with reproduction evidence. Review findings for shared causes and dependencies; implement coherent fixes with regression tests, then rerun the full inventory. Stop at a clean pass or blocked handoff. Ask before production, sensitive data, or destructive actions.

Close your search-visibility gaps

Fix the highest-impact crawl, indexation, intent, citation, and answer-readiness gaps first, in priority order.

prompt
→ Claude
Run an SEO/GEO audit across crawlability, indexation, page intent, titles, internal links, structured data, source citations, and answer-first content. Rank the gaps by expected impact, fix the highest-leverage issue, then rerun the same crawl and target-query benchmark across search engines and AI answer engines. Repeat until no critical technical issues remain, every priority query maps to a clear answer-ready page, and the benchmark shows no high-impact gap left to fix.

Sweep production errors to root cause

Trace actionable production errors to their root cause, verify the fix, open a PR, and stop cleanly when nothing needs action.

prompt
→ Claude
Review our production logs for errors. If you find an actionable issue, trace it to its root cause, fix it, verify the fix, and open a pull request. If no actionable errors are present, stop without making changes.

Refactor in tested checkpoints

Reshape the architecture in small, independently reviewed steps — live-test, commit a checkpoint, and log progress each pass.

prompt
→ Claude
Refactor until you are happy with the architecture. After each significant step, live-test the system, run autoreview, and commit. Track progress in /tmp/refactor-{projectname}.md.

Content operations monitor via custom loop.md

Loop/loop

A marketing-facing loop.md playbook that turns a bare /loop into a recurring content-ops sweep: checks GA4 for week-over-week organic traffic drops, scans GSC for position 4-15 query opportunities, and audits WordPress posts for broken internal links and missing meta descriptions — reporting one line when everything is green.

prompt
→ Claude
/loop 15m (Save the following as .claude/loop.md so the bare /loop picks it up as its playbook.) # .claude/loop.md — Content Operations Monitor Check the following every iteration: 1. Pull the latest GA4 data for kokasexton.com. If any post dropped more than 30% in organic traffic week-over-week, flag it with the URL and the percentage drop. 2. Scan GSC for new queries where we rank positions 4-15 and impressions grew >20% week-over-week. List the top 3 opportunities. 3. Check the WordPress admin for any posts with broken internal links or missing meta descriptions. Fix silently if fewer than 5 issues. Report if more. 4. If everything is green, reply with one line: "Content ops clean — nothing needs attention." Cap the run at 15 passes.

Custom loop.md — Project-Level Default for Bare /loop

Loop/ralph

A team-config pattern: a loop.md file in the project root overrides the built-in maintenance prompt, so any teammate running bare /loop gets your project's canonical loop — run lint, typecheck, and tests, fix anything red, stop when clean.

prompt
→ Claude
Put a `loop.md` in the project root to replace the built-in maintenance prompt when a user runs bare `/loop` — e.g., "run lint + typecheck + tests; fix anything red; update CHANGELOG; stop when clean." Every teammate's bare `/loop` now runs your loop.

Codex App Automations (Scheduled Agent Runs)

Loop/ralph★ OpenAI

Codex's native answer to scheduled agent loops: define a prompt plus a schedule in the Codex app and it runs in the cloud on cadence — nightly dependency audits, morning issue triage — with no terminal open. The Codex-side equivalent of Claude Code Routines.

prompt
→ Claude
Define an Automation in the Codex app: a prompt + schedule that runs in the cloud on cadence (e.g., nightly dependency audit, morning triage of new issues), no terminal open. Guardrails: Stop when the goal is verifiably met, or stop after 15 iterations, whichever comes first. Verify each pass by running the relevant tests or checks — self-reported success does not count. Keep changes minimal and never touch files outside the task’s scope.

Ralph Overnight Builds — Progressive Curriculum Entry

Loop/ralph

A graduated path to unattended Ralph runs: start with a single bounded task, add a PROMPT.md spec file, add verification, and only then remove the human from the loop for overnight builds.

prompt
→ Claude
Staged path from basic prompt → PROMPT.md spec → overnight Ralph run: start with a single bounded task, add a spec file, add verification, only then remove the human from the loop. Cap the run at 25 iterations; leave remaining work for the next session.

Runaway-Bill Guardrail Loop (Watchdog Beside the Worker)

Loop/ralph

A cost-safety pattern that pairs every overnight loop with a second, dumber loop whose only job is stopping the first: spend alerts, a hard iteration cap, and a cron check that kills the worker when token burn spikes or the same command keeps repeating.

prompt
→ Claude
Pair every overnight loop with a watchdog: spend/usage alert thresholds, a hard `MAX_ITER`, and a cron check that kills the loop process if tokens-per-minute spikes or the same command repeats N times. The watchdog is a second, dumber loop whose only job is stopping the first one. Cap the run at 25 iterations; leave remaining work for the next session.

Karpathy-Style CLAUDE.md Self-Check Protocol for Loops

Loop/ralphAndrej Karpathy

A self-check protocol embedded in CLAUDE.md that every loop iteration obeys before ending a turn: re-read the goal, diff the changes against it, run the verification command, and state what remains — a ritual that catches drift between iterations.

prompt
→ Claude
Preamble rules embedded in CLAUDE.md that every loop iteration obeys: before ending a turn, re-read the goal, diff your changes against it, run the verification command, and explicitly state what remains — a self-check ritual that catches drift between iterations. (Community template descended from Andrej Karpathy's circulated CLAUDE.md rules.) Guardrails: Stop when the goal is verifiably met, or stop after 15 iterations, whichever comes first. Keep changes minimal and never touch files outside the task’s scope.

Issue-to-Merge GitHub-Native Loop (Engineer the Reload)

Loop/ralph

A full-lifecycle loop where every piece of workflow state lives in GitHub — issues, labels, PR comments — and repo files, so each cold-start session rehydrates from GitHub rather than a conversation. Built on the official claude-code-action.

prompt
→ Claude
Run Claude Code across the full lifecycle — issue intake → branch → implement → PR → review fixes → merge — with ALL workflow state externalized to GitHub (issues, labels, PR comments) and repo files. Each session starts cold and rehydrates from GitHub state; "the chat being gone doesn't cost you anything." Cap the run at 25 iterations; leave remaining work for the next session.

Stop-Hook Ralph (Deterministic Loop Without Bash)

Loop/ralph

A Ralph variant that lives inside a single Claude Code session: a stop hook re-injects the task prompt whenever the agent tries to end its turn, trading the bash while-loop's fresh context for a persistent session.

prompt
→ Claude
Use a Claude Code stop hook that re-injects the task prompt whenever the agent tries to end its turn, until a completion condition or hard iteration cap is met — Ralph semantics inside one session instead of a bash `while` wrapper. Cap the run at 25 iterations; leave remaining work for the next session.

Codex CLI as an MCP Tool Inside an Agents-SDK Loop

Loop/ralph★ OpenAI

An outer-planner/inner-coder loop from an official OpenAI recipe: an Agents SDK orchestrator plans and verifies while Codex CLI, wrapped as an MCP server, performs one bounded code change per turn.

prompt
→ Claude
Wrap Codex CLI as an MCP server and drive it from an OpenAI Agents SDK orchestrator loop — the outer agent plans/verifies, the inner Codex call does one bounded code change per turn. Guardrails: Stop when the goal is verifiably met, or stop after 15 iterations, whichever comes first. Verify each pass by running the relevant tests or checks — self-reported success does not count. Keep changes minimal and never touch files outside the task’s scope.

Codex CI Autofix Loop (Fix Failing GitHub Actions)

Loop/ralph★ OpenAI

An event-triggered loop where a red GitHub Actions build invokes `codex exec` non-interactively with the failing logs and repo, and Codex proposes a fix as a PR or patch artifact — one bounded iteration per CI failure.

prompt
→ Claude
CI job: on workflow failure, run `codex exec` non-interactively with the failing logs + repo, have it generate and propose a fix (PR or patch artifact) automatically. `codex exec` runs one task and exits, so each CI failure is one bounded iteration.

Codex Iterative Repair Loop (JSON-Schema Review → Repair)

Loop/ralph★ OpenAI

OpenAI's first-party loop recipe: a script alternates a Codex review pass that emits machine-readable findings with a repair pass fed those findings verbatim, looping until validation passes, attempts run out, progress stalls, or a decision needs human review.

prompt
→ Claude
Script alternates two `codex exec` calls: (a) review pass with a JSON schema output ("list remaining issues as machine-readable findings"), (b) repair pass fed those findings verbatim. Loop while findings remain, capped by max attempts. Stops for one of four reasons: validation passes, max attempts reached, remaining delta stops changing, or next decision needs human review.

Cursor "Iterate Until Tests Pass, Never Touch the Tests"

Loop/ralph

First-party Cursor guidance for the iterate-until-green loop, with the key anti-reward-hacking clause: the agent may never modify the tests it is trying to satisfy. Works in Cursor, Claude Code /goal, and Codex.

prompt
→ Claude
"Write code that makes these tests pass. Do NOT modify the tests. Keep iterating — run the suite, fix failures, run again — until all tests pass." (paraphrase of Cursor's official agent best-practices guidance)

Loop cost guardrails pattern

Loop/ralph

The four-part cost guardrail every agent loop should ship with: a hard iteration cap, a stop-after-N-turns clause in the goal text, a budget limit on SDK loops, and a /cost check inside the loop body.

prompt
→ Claude
Every loop gets: `MAX_ITER=20` hard cap, "or stop after N turns" in the /goal text, `max_budget_usd` on SDK loops, and a /cost check in the loop body.

Schedules + goals + subagents design framework

A design framework for AI agent loops built on three questions — when should it run (schedule), what does done mean (goal), and who does the isolated pieces (subagents) — with worked examples in Claude Code and Codex.

prompt
→ Claude
Design framework: choose schedule (when), goal (what done means), subagents (who does isolated pieces) — with worked examples in Claude Code and Codex. Guardrails: Stop when the goal is verifiably met, or stop after 15 iterations, whichever comes first. Verify each pass by running the relevant tests or checks — self-reported success does not count. Keep changes minimal and never touch files outside the task’s scope.

/goal + Routines overnight combo

Loop/scheduleSabrina Ramonov

The two-layer answer to how do I run this overnight: /goal drives in-session work to done, while a scheduled Routine keeps recurring unattended work running on Anthropic's cloud with your laptop closed.

prompt
→ Claude
/schedule a Routine (runs on Anthropic cloud, laptop closed) for recurring unattended work, and use `/goal` for in-session iterate-to-done — the two-layer overnight pattern. Guardrails: Stop when the goal is verifiably met, or stop after 15 iterations, whichever comes first. Verify each pass by running the relevant tests or checks — self-reported success does not count.

Spec-first Ralph (PLAN.md-driven)

Loop/ralphHumanLayer

The spec-driven maturation of the Ralph loop: each fresh-context iteration reads PLAN.md, implements the highest-priority unchecked item, checks it off, and commits — so the spec file evolves alongside the codebase.

prompt
→ Claude
Ralph variant where the loop prompt is "read PLAN.md, pick highest-priority unchecked item, implement, check it off, commit, exit" — spec file evolves with the codebase. Guardrails: Stop when the goal is verifiably met, or stop after 15 iterations, whichever comes first. Keep changes minimal and never touch files outside the task’s scope.

claude-progress.txt harness pattern (Anthropic)

Loop/ralph★ Anthropic

Anthropic's first-party file-as-memory harness for long-running agents: every fresh-context session recovers state from a progress file and the git log, does one unit of work, updates the file, commits, and exits.

prompt
→ Claude
Long-running agent harness: each fresh-context session starts by reading `claude-progress.txt` + git log to recover state, does one unit of work, updates the progress file, commits, exits. Initializer session sets up the file; coder sessions loop. Guardrails: Stop when the goal is verifiably met, or stop after 15 iterations, whichever comes first.
