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

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.

Implementation note

When to use: your team runs bare /loop often enough that the built-in default maintenance prompt is a missed opportunity — you want every teammate's reflexive /loop to run your project's canonical checklist instead. How it works: place a loop.md file in the project root; it replaces the built-in maintenance prompt whenever someone runs bare /loop. A typical loop.md: run lint, typecheck, and tests; fix anything red; update the CHANGELOG; stop when clean. Because the file is versioned with the repo, the team's default loop evolves through normal code review. Safety: this is configuration, not a runnable loop itself — the safety of bare /loop becomes whatever your loop.md says, so write an explicit stop condition (stop when clean) and keep the scope conservative, since people will invoke it casually. Note the documented limit: loop.md maxes out at 25KB per Anthropic's docs. Review changes to it like code, because it is code.

Ship production-grade apps autonomously

Hand an idea to Claude Code; it authors specs, designs, builds, tests, secures, and ships until enterprise done or budget exhausted.

Never points at anything with users. This is v2. It keeps the strong core of the original spec (external reviewer, ratchet, guard hook, Junkion style) and adds the three phases the original left thin relative to the actual goal: PRD authoring, a design phase, and a real enterprise DoD including security, CI, docs/observability, and design quality (with quality plugins auto-installed). --- ## 0.

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. 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.
