All checks were successful
check / check (push) Successful in 22s
Close three gaps between the containerised-lint rule and its first adopters
The rule landed in 12e8db8 is right; these are the three places where the
canonical text and the repos implementing it can diverge without either
side looking wrong.

1. `.dockerignore` excluding the agent scratch directory is now stated as a
   correctness precondition of containerised linting rather than a
   context-size measure. `Dockerfile.lint` lints whatever `COPY . .` copies,
   and language toolchains discover files by walking the tree instead of
   reading `.gitignore`, so a nested worktree in the context puts the
   foreign-tree false reds back inside the container — in the convincing
   form, where the findings are real but belong to another checkout.
   sneak/quak measured the same discovery mechanism taking a test count
   from 210 to 1050.

2. The cache-bust build arg is fixed at `CHECK_EPOCH` in `Dockerfile.lint`
   as well as in `Dockerfile`. A per-file name is invisible to the grep that
   proves every build is busted, which makes a renamed guard and a missing
   guard read identically. sneak/quak's lint file currently names it
   `LINT_EPOCH`.

3. The formatting check must run in exactly one of the two images, and
   either placement is allowed. Splitting lint out of the `Dockerfile` is
   precisely the moment `fmt-check` gets dropped from both, and running the
   formatter beside the linters is the better shape wherever it is the same
   pinned dependency — it takes the last host toolchain off the checked
   path for the reason the linter came off it.

Both checklists carry the matching items, since a repo that satisfies the
policy prose but not the checklist is the drift this is meant to stop.

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.
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, one for each new repo file, 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

separate commit."

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: runs script/bootstrap, then script/install-precommit
  • script/projectname — output the project name (our own extension); used by script/docker for the image tag
  • script/test — run the test suite (no tests defined here)
  • script/lint — lint the markdown files, by building Dockerfile.lint. The linter runs in a container, always: it is never installed on the host and never invoked there. Linting happens as a build step, so a successful build is a clean lint, and the same per-invocation CHECK_EPOCH nonce used elsewhere is what stops Docker serving that lint from cache on an unchanged tree
  • script/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). Needs a docker daemon, since script/lint is a container build
  • script/docker — build the Docker image, tagged via script/projectname (byte-identical across repos); passes the same CHECK_EPOCH nonce as script/cibuild
  • script/cibuild — cd to the repo root, run script/lint first, then assign epoch="$(date +%s%N)$$" and docker build --build-arg CHECK_EPOCH="$epoch" . (what CI runs). Two container builds: the lint image, then the main image, which runs script/test and script/fmt-check but deliberately not make check — that would nest a docker build inside a build step. A bare docker build . fails closed on purpose
  • script/precommit — run by the git pre-commit hook (our own extension); calls script/check
  • script/install-precommit — installs the git pre-commit hook (our own extension); make hooks shims 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
