script/cibuild was a plain `docker build .`, and the Dockerfile does `COPY . .` followed by `RUN make check`. Docker invalidates a COPY layer only when the copied content changes, so on an unchanged tree the check layer was served from cache, the suite never ran, and the build still exited 0. Measured here: run 1 took 18.5s and ran the suite; run 2 on a byte-identical tree took 0.286s with `RUN make check` CACHED. script/cibuild and script/docker now assign a per-invocation nonce on its own line and pass it as --build-arg CHECK_EPOCH. The Dockerfile declares ARG CHECK_EPOCH, guards it with `[ -n "$CHECK_EPOCH" ] || exit 1`, and expands it into the check command. Post-fix, two consecutive runs both execute make check (17.4s / 8.1s) with `RUN script/bootstrap` still CACHED, so dependency layers are untouched and the build ceiling is not at risk. The guard is what makes a bare `docker build .` — the command REPO_POLICIES named verbatim — fail closed rather than reuse the empty and therefore stable cache key; verified failing in 0.455s. Holding the epoch constant restores the false green (run 2 fully CACHED), which pins the varying value as the operative mechanism rather than a coincidence. REPO_POLICIES.md carried the false guarantee as org-canonical text in two places, and its Go multistage template had check steps in two stages; ARG is stage-scoped, so both stages get the treatment or the fleet inherits the half-fixed shape.

prompts
prompts is an MIT-licensed collection of LLM prompts by @sneak, including development policy prompts and other useful prompts for working with large language models.
Quick Start
Existing Repo
Run from within the repo you want to bring up to standards. Clone the prompts repo once, then run both commands in order.
export TD="$(mktemp -d)"
git clone --depth 1 https://git.eeqj.de/sneak/prompts.git "$TD"
Repository structure and policies:
claude "Read $TD/prompts/REPO_POLICIES.md and
$TD/prompts/EXISTING_REPO_CHECKLIST.md, then bring this repo up to those
standards. Your scope is repo scaffolding and policy compliance:
Makefile, Dockerfile, .dockerignore, .gitignore, .editorconfig, CI
workflow, README sections, LICENSE, REPO_POLICIES.md, and any
language-specific config files (.golangci.yml, .prettierrc, etc.).
You must also run the formatter (make fmt) and fix any linter errors
(make lint) so that make check passes — this will touch source code,
but do not restructure, refactor, or rewrite any application logic.
Follow the policies yourself: work on a feature branch, never git add -A,
and make each logical change a separate commit (e.g. one commit for
formatting, one for linter fixes, one for README updates, one for each
new repo file added, etc.)."
Code style and conventions:
claude "Read $TD/prompts/CODE_STYLEGUIDE.md and whichever
language-specific styleguides in $TD/prompts/ apply to this repo
(CODE_STYLEGUIDE_GO.md, CODE_STYLEGUIDE_JS.md, CODE_STYLEGUIDE_PYTHON.md,
GO_HTTP_SERVER_CONVENTIONS.md). Then review the application code in this
repo and bring it into compliance with those coding standards. Your scope
is application code structure and style: naming, patterns, error
handling, project layout, and conventions described in the styleguides.
Do not modify repo scaffolding (Makefile, Dockerfile, CI workflow,
.gitignore, .editorconfig, etc.) — only application code. Work on a
feature branch, never git add -A, and make each logical change a
separate commit."
New Repo
Run from inside the directory where you want to create a new repo. Clone the prompts repo once, then run both commands in order.
export TD="$(mktemp -d)"
git clone --depth 1 https://git.eeqj.de/sneak/prompts.git "$TD"
Repository scaffolding:
claude "Read $TD/prompts/REPO_POLICIES.md and
$TD/prompts/NEW_REPO_CHECKLIST.md, then set up this new repo according
to those standards. Your scope is repo structure and required files:
README.md, LICENSE, REPO_POLICIES.md, Makefile, Dockerfile, .dockerignore,
.gitignore, .editorconfig, CI workflow, and language-specific config.

Getting Started
git clone https://git.eeqj.de/sneak/prompts.git
cd prompts
Prompts are stored as Markdown files in prompts/. Copy or reference them as
needed in your projects.
Entrypoints
This repository adheres to the
Scripts to Rule Them All
standard: normalized scripts in script/ are the entrypoints for the
development workflow, and the Makefile targets are thin shims that call them.
The scripts are POSIX sh (not bash) so they run in minimal containers such as
alpine. We provide:
script/bootstrap— install all dependencies (yarn install)script/setup— set up the repo for development after a fresh clone: runsscript/bootstrap, thenscript/install-precommitscript/projectname— output the project name (our own extension); used byscript/dockerfor the image tagscript/test— run the test suite (no tests defined here)script/lint— lint the markdown files with prettierscript/fmt— format all markdown files with prettier (writes)script/fmt-check— check formatting (read-only)script/check— run all checks:test,lint,fmt-check(our own extension)script/docker— build the Docker image, tagged viascript/projectname(byte-identical across repos)script/cibuild— cd to the repo root anddocker build --build-arg CHECK_EPOCH="$epoch" .(what CI runs; the image build runsscript/check, and the per-invocationCHECK_EPOCHnonce is what stops Docker serving that check from cache on an unchanged tree — a baredocker build .fails closed on purpose)script/precommit— run by the git pre-commit hook (our own extension); callsscript/checkscript/install-precommit— installs the git pre-commit hook (our own extension);make hooksshims to it
make hooks installs the pre-commit hook that runs script/precommit.
Rationale
LLM prompts, especially development policies, benefit from version control and a single authoritative source. This repo provides a central place to maintain, share, and evolve prompts across projects.
Design
The repository is a collection of Markdown files organized in the prompts/
subdirectory. Each file contains one or more related prompts or policy
documents. There is no build step or runtime component; the prompts are consumed
by copying them into other projects or referencing them directly.
Template Repos
These template repositories implement the policies defined in this repo and serve as starting points for new projects. They must be kept in sync when policies change.
- template-app-go — Go HTTP server template (Uber fx, chi, SQLite, session auth, Prometheus metrics)
- template-app-js — JavaScript SPA template (Vite, Tailwind CSS v4, nginx Docker deployment)
- template-app-python — Python web application template (FastAPI, uvicorn, pytest, black, ruff)
When updating policies in this repo, also update the template repos to match (Makefile targets, Dockerfile conventions, CI workflows, required files, etc.).

TODO
- Add more prompt templates for common development tasks
