Re-vendor the canonical files from sneak/prompts at dd4027b (closes #121)
check / check (push) Waiting to run
Details

Browse Source 
The vendored files are copies from sneak/prompts dd4027b, with this
repository's own entries after the canonical content. golangci-lint is
v2.14.0. Lint and test are phases of the Dockerfile, which script/lint
and script/test build with --no-cache; Dockerfile.lint and
script/lint-darwin are gone, and the lint phase also checks the macOS
build. The tests run on the Debian Go image with cgo and the race
detector. script/cibuild bootstraps, runs script/check and builds the
image; CHECK_EPOCH and the memlock ulimit are gone. Go's build cache
stays in a cache mount, out of the test image's layer. The rules in
CLAUDE.md that AGENTS.md lacked are now in AGENTS.md.

# .dockerignore does NOT use .gitignore semantics. Docker matches with
# moby/patternmatcher: filepath.Match plus `**`, so `*` does not cross
# `/` and an unprefixed pattern is anchored at the context root. Every
# depth-independent pattern therefore needs `**/`, or `config/.env` and
# `certs/server.key` still ship while this file reads as solved. Only
# genuinely root-anchored entries go unprefixed. Never transplant these
# into .gitignore, where `**/` is wrong.
#
# Matching is case-sensitive, so secrets use character ranges rather
# than an ALL-CAPS twin, which would still miss `Server.Key`.
#
# Extend with this repo's own host-built artifacts, written anchored:
# `/myapp`, never `**/myapp`, which also matches `cmd/myapp/` and
# deletes the package directory from the context.
# .git is sent without its config. Without a VERSION build argument the
# stage that compiles runs `git describe --tags --always` on .git, which
# does not need .git/config; that file can hold a credential, such as a
# password in a remote URL or the token the CI checkout step stores there.
.git/config
# Each submodule keeps a config with the same exposure in its git directory
# under .git/modules/, nested again for a submodule's own submodules, or in
# its own .git directory when it keeps one.
# KNOWN GAP: a submodule whose name has a `config` segment (`config`,
# `deploy/config`, `config/lib`) loses its whole git directory, because
# `**/.git/modules/**/config` also matches that segment's directory
# under .git/modules/. Go's version stamping then fails the build;
# nothing leaks. Name such a submodule without that segment:
# `git submodule add --name`.

# IMPORTANT RULES
- Claude is an inanimate tool. The spam that Claude attempts to insert into
commit messages (which it erroneously refers to as "attribution") is not
attribution, as I am the sole author of code created using Claude. It is
corporate advertising for Anthropic and is therefore completely unacceptable
in commit messages.
- Tests should always be run before committing code. No commits should be made
that do not pass tests.
- Code should always be formatted before committing. Do not commit unformatted
code.
- Code should always be linted and linter errors fixed before committing. NEVER
commit code that does not pass the linter. DO NOT modify the linter config
unless specifically instructed.
- The test suite is fast and local. When running tests, NEVER run individual
parts of the test suite, always run the whole thing by running "make test".
- Do not stop working on a task until you have reached the definition of done
provided to you in the initial instruction. Don't do part or most of the work,
do all of the work until the criteria for done are met.
- When you complete each task, if the tests are passing and the code is
formatted and there are no linter errors, always commit and push your work.
Use a good commit message and don't mention any author or co-author
attribution.
- Do not create additional files in the root directory of the project without
asking permission first. Configuration files, documentation, and build files
are acceptable in the root, but source code and other files should be
organized in appropriate subdirectories.
- Do not use bare strings or numbers in code, especially if they appear anywhere
more than once. Always define a constant (usually at the top of the file) and
give it a descriptive name, then use that constant in the code instead of the
bare string or number.
- If you are fixing a bug, write a test first that reproduces the bug and fails,
and then fix the bug in the code, using the test to verify that the fix
worked.
- When implementing new features, be aware of potential side-effects (such as
state files on disk, data in the database, etc.) and ensure that it is
possible to mock or stub these side-effects in tests when designing an API.
- When dealing with dates and times or timestamps, always use, display, and
store UTC. Set the local timezone to UTC on startup. If the user needs to see
the time in a different timezone, store the user's timezone in a separate
field and convert the UTC time to the user's timezone when displaying it. For
internal use and internal applications and administrative purposes, always
display UTC.
- When implementing programs, put the main.go in ./cmd/<program_name>/main.go
and put the program's code in ./internal/<program_name>/. This allows for
multiple programs to be implemented in the same repository without cluttering
the root directory. main.go should simply import and call
<program_name>.CLIEntry(). The full implementation should be in
./internal/<program_name>/.
- When you are instructed to make the tests pass, DO NOT delete tests, skip
tests, or change the tests specifically to make them pass (unless there is a
bug in the test). This is cheating, and it is bad. You should only be
modifying the test if it is incorrect or if the test is no longer relevant. In
almost all cases, you should be fixing the code that is being tested, or
updating the tests to match a refactored implementation.
- Always write a `Makefile` with the default target being `test`, and with a
`fmt` target that formats the code. The `test` target should run all tests in
the project, and the `fmt` target should format the code. `test` should also
have a prerequisite target `lint` that should run any linters that are
configured for the project.
- After each completed bugfix or feature, the code must be committed. Do all of
the pre-commit checks (test, lint, fmt) before committing, of course. After
each commit, push to the remote.
- Always write tests, even if they are extremely simple and just check for
correct syntax (ability to compile/import). If you are writing a new feature,
write a test for it. You don't need to target complete coverage, but you
should at least test any new functionality you add.
- Always use structured logging. Log any relevant state/context with the
messages (but do not log secrets). If stdout is not a terminal, output the
structured logs in jsonl format. Use go's log/slog.
- You do not need to summarize your changes in the chat after making them.
Making the changes and committing them is sufficient. If anything out of the
ordinary happened, please explain it, but in the normal case where you found
and fixed the bug, or implemented the feature, there is no need for the
end-of-change summary.

target shims to it); and `script/projectname` (literally that filename) simply
outputs the project's name. Scripts that need the name call
`script/projectname` — e.g. `script/docker` assembles its image tag from it —
so those scripts stay byte-identical across all repos. Repo-type-specific
pre-commit extras (e.g. `go mod tidy` verification in Go repos) belong in
`script/precommit`, not in the hook itself. Model scripts are at
repo root, runs `script/bootstrap`, runs `script/check`, and builds the image
with the version; the Gitea workflow calls it. **`script/cibuild` runs
`script/bootstrap` first**, because the workflow checks out the repo and runs
nothing else, while `script/fmt-check` runs the formatter on the host: on a
pristine checkout with nothing installed the run dies there, after the
containerised gates have passed. **The bootstrap alone is not enough**:
`script/bootstrap` installs node and yarn under nvm and leaves neither on the
`PATH` of the shell that called it, so a bare `yarn` still exits 127. The host
entrypoints that need yarn — `script/fmt` and `script/fmt-check` — therefore
source nvm for the pinned node version before invoking it, exactly as
`script/bootstrap`'s own install step does. A runner carrying nothing but
docker and git then gets through `script/check`. Four further scripts are our
own extensions to the standard: `script/check` runs `script/test`,
`script/lint` and `script/fmt-check`; `script/precommit` is what the git
pre-commit hook runs, and it calls `script/check`; `script/install-precommit`
installs the git pre-commit hook (the `make hooks` target shims to it); and

contributor should be able to understand the entire development workflow by
reading the Makefile.
- Every repo should have a `Dockerfile`. All Dockerfiles must run `make check`
as a build step so the build fails if the branch is not green. For non-server
repos, the Dockerfile should bring up a development environment and run
`make check`. For server repos, `make check` should run as an early build
stage before the final image is assembled. Dockerfiles install development
prerequisites by running `script/bootstrap` rather than duplicating installs
inline; COPY `script/` and the dependency manifests (`package.json` +
`yarn.lock`, `go.mod` + `go.sum`, etc.) before running it so the bootstrap
layer stays cached until dependencies change.
- Every repo should have a `Dockerfile`, and it carries the repo's gates: a
`lint` phase and a `test` phase, with the final stage depending on both so the
image cannot be built unless they pass. For non-server repos the final stage
brings up a development environment; for server repos it is the runtime image.
The gate phases and the build stage start from their pinned base images and
install what those images lack either inline, as the canonical Go `Dockerfile`
below does for `git`, or by running `script/bootstrap`, as the `prompts`
repo's own `Dockerfile` does for its yarn packages. The development
environment stage installs development prerequisites by running
`script/bootstrap` rather than duplicating its installs inline. A stage that
runs `script/bootstrap` COPYs `script/` and the dependency manifests
(`package.json` + `yarn.lock`, `go.mod` + `go.sum`, etc.) before running it.
- **Dockerfiles must use a separate lint stage for fail-fast feedback.** Go
repos use a multistage build where linting runs in an independent stage based
on the `golangci/golangci-lint` image (pinned by hash). This stage runs
`make fmt-check` and `make lint` before the full build begins. The build stage
then declares an explicit dependency on the lint stage via
`COPY --from=lint /src/go.sum /dev/null`, which forces BuildKit to complete
linting before proceeding to compilation and tests. This ensures lint failures
surface in seconds rather than minutes, without blocking on dependency
download or compilation in the build stage.
- **Linting and testing run in Docker, as phases of the `Dockerfile`.** There is
no separate lint file. `script/lint` and `script/test` each build one phase
and nothing else:
The standard pattern for a Go repo Dockerfile is:
```sh
docker build --no-cache --target lint -t "$(script/projectname)-lint" .
docker build --no-cache --target test -t "$(script/projectname)-test" .
```
**A stage that is not the last one in the file is built only when the final
stage's chain depends on it, or when `--target` names it.** That is why the
two gates are always invoked by name here, and why the final stage carries a
`COPY --from=` of a harmless file from each of them: without that edge a
plain `docker build .` builds the last stage alone and exits 0 having linted
and tested nothing.
**Every `docker build` in `script/` is tagged**, here and in
`script/cibuild` and `script/docker`. An untagged build leaves a dangling
image behind on every invocation, on every developer host and every CI
runner; a tagged one replaces the previous image.
Inside a phase the tool is invoked directly — `golangci-lint`, `go test`,
`eslint`, `prettier` — never through `make lint` or `script/test`, which are
themselves a `docker build` and would recurse into a daemon that does not
exist in a build step. Formatting is the exception and stays on the host:
`script/fmt` writes the working tree, and `script/fmt-check` is its
read-only twin.
**No lint verdict may come from a host invocation of the linter.** On a
shared host golangci-lint reads a result cache keyed on file content rather
than location, so a second checkout of the same content is served the first
one's findings, and a host-global lock in `$TMPDIR` makes concurrent runs
exit non-zero with `parallel golangci-lint is running` — a status a caller
cannot tell from real findings. Both have produced wrong verdicts in this
org, in both directions. A container has its own cache, its own `TMPDIR` and
a digest-pinned binary, so neither is reachable.
- **Any build that runs checks is built with `--no-cache`.** Docker invalidates
a `COPY` layer only when the copied content changes, so on an unchanged tree
the check `RUN` is served from cache, nothing executes, and the build still
exits 0. Every `docker build` in `script/` therefore passes `--no-cache`:
`script/lint`, `script/test`, `script/cibuild` and `script/docker` are the
four, and there is no fifth — `script/check` runs the two gate phases and
`script/fmt-check`, and builds no image of its own. A bare `docker build .` is
not evidence that anything ran: a sub-second build reporting success is a
cache hit, not a result. Never invalidate by pruning — `docker builder prune`
and friends destroy a build cache shared with every other build on the host.
When a check is added or changed, prove it works by planting a defect it must
catch and watching the run fail on it, then revert the defect. A green run
alone shows neither that the check ran nor that it covers what it should.
- **The gate phases are separate stages, and the build stage depends on both.**

Key points:
- The lint stage uses the `golangci/golangci-lint` image directly (it
includes both Go and the linter), so there is no need to install the
linter separately.
- `COPY --from=lint /src/go.sum /dev/null` is a no-op file copy that creates
a stage dependency. BuildKit runs stages in parallel by default; without
this line, the build stage would not wait for lint to finish and a lint
failure might not fail the overall build.
- The lint phase uses the `golangci/golangci-lint` image directly (it has
both Go and the linter), so nothing needs installing.
- `COPY --from=<phase> /src/go.sum /dev/null` is a no-op copy whose only
purpose is the ordering edge. BuildKit runs stages in parallel by default,
and a stage nothing depends on is not built at all, so without these two
lines a red gate would not fail the build.
- Keep the runtime stage last, and if you add a stage after it, give it the
same two copies. A plain `docker build .` builds the last stage's chain
and nothing else.
- If the project uses `//go:embed` directives that reference build artifacts
(e.g. a web frontend compiled in a separate stage), the lint stage must
(e.g. a web frontend compiled in a separate stage), the lint phase must
create placeholder files so the embed directives resolve. Example:
`RUN mkdir -p web/dist && touch web/dist/index.html web/dist/style.css`.
The lint stage should not depend on the actual build output — it exists to
fail fast.
- If the project requires CGO or system libraries for linting (e.g.
`vips-dev`), install them in the lint stage with `apk add`.
- The build stage runs `make test` after compilation setup. Tests run in the
build stage, not the lint stage, because they may require compiled
artifacts or heavier dependencies.
- If the project requires CGO or system libraries for linting, install them
in the lint phase. The `golangci/golangci-lint` image is Debian-based and
has no `apk`, so install with `apt-get` under the Debian package name
(`libvips-dev`, where alpine says `vips-dev`), and delete the package
lists in the same `RUN`, so the layer does not keep them:
```dockerfile
RUN apt-get update \
&& apt-get install -y --no-install-recommends libvips-dev \
&& rm -rf /var/lib/apt/lists/*
```
- `.dockerignore` lets `.git` into the build context. It keeps out every git
`config` at any depth (`**/.git/config`, `**/.git/modules/**/config`): the
repository's own, each submodule's under `.git/modules/`, and that of a
submodule keeping its own `.git` directory. `git describe` does not need
them, and each can hold a credential: a password in a remote URL, or the
token the CI checkout step stores there. A submodule whose name has a
`config` segment (`config`, `deploy/config`, `config/lib`) loses its whole
git directory to `**/.git/modules/**/config`, and Go's version stamping
then fails the build: give it a name without that segment
(`git submodule add --name`). The stage that compiles has `git` (the
Debian Go image has it; an alpine one needs `apk add --no-cache git`) and
takes the version from the `VERSION` build argument when one is given,
otherwise from `git describe --tags --always`. That gives the tag on a
tagged commit; on a later commit, the tag, the number of commits since it
and the short commit (`v1.2.3-4-gabc1234`); and the short commit when no
tag is reachable. The stage that compiles also marks its working directory
safe for git (`git config --system --add safe.directory /src`): a context
sent as a tar stream keeps the sender's file owners, and git refuses a
checkout owned by another user, so the version would come out empty.
`ARG VERSION` has no default, and the build fails if the context carries
`.git` and the version still comes out empty, `dev` or `unknown`. A plain
`docker build .` with no build arguments must succeed; a Dockerfile that
refuses an empty build argument drops that refusal and keeps the argument.
- Every repo should have a Gitea Actions workflow (`.gitea/workflows/`) that
runs `script/cibuild` (which runs `docker build .`) on push. Since the
Dockerfile already runs `make check`, a successful build implies all checks
pass.
runs `script/cibuild` on push, and checks out the repo as its only other step.
That script bootstraps, runs the gate phases, and then builds the image, so a
successful run means every check passed; a bare `docker build .` does not
carry the same guarantee, because its gate phases may come from the cache. The
image build is uncached and so runs the gate phases a second time. That is the
price of the rule above, and it is worth paying: the image that ships is built
from a run of its own gates rather than from a cache entry. A separate
workflow limited to `main` by a `branches` list under `on: push` cannot be
checked by review: to try a change to it, add the feature branch to that list
and push, then remove the branch from the list again before merging. Keep any
job in it that publishes behind `if: github.ref_name == 'main'`, so the run
from the feature branch publishes nothing.

`-count=1` is required on both invocations: it defeats Go's test _result_
cache, so neither run can report a stored pass in place of running the
tests. It leaves the build cache alone, so it costs the runtime of the suite
and no recompilation.
That cache is Go's own, separate from Docker's layer cache. Go stores a
passing result in its cache directory (`GOCACHE`), and when the same tests
run again on unchanged code it prints that result, marked `(cached)`,
without running them. That matters on a developer's machine, where this
target runs and the directory lasts from one run to the next. The `test`
phase of the `Dockerfile` needs no `-count=1`: its base image holds no
result for this repo's tests and nothing before its `go test` step runs a

are not a `.dockerignore` and must not be transplanted into one unmodified.
- **`.dockerignore` does not use `.gitignore` semantics, and copying patterns
across unmodified leaves secrets in the build context.** Docker matches with
`moby/patternmatcher`: `filepath.Match` semantics plus a `**` extension, so
`*` does not cross `/` and a pattern without a leading `**/` is anchored at
the build-context root. A `.dockerignore` listing `.env`, `*.pem` and `*.key`
therefore excludes only the copies at the repository root, while `config/.env`
and `certs/server.key` still reach the context and can land in an image layer
— which is more dangerous than a short file with no secret patterns at all,
because it reads as solved and stops anyone looking. Give every
depth-independent pattern the `**/` prefix and leave only genuinely
root-anchored entries unprefixed: `.claude`, and the repo's own host-built
binary, written `/myapp` and never `**/myapp`, which would also match
`cmd/myapp/` and delete the package directory from the context. Matching is
case-sensitive, and an ALL-CAPS twin per pattern still misses `Server.Key`, so
secret names use character ranges — `**/*.[kK][eE][yY]`, `**/*.[pP][eE][mM]`,
and likewise for `.envrc` and the extensionless SSH keys. Where such a pattern
also catches something the build needs, re-include it with a negation
(`!docs/example.env`); deleting the pattern reopens the exposure for every
other file it covers. Fetch the standard `.dockerignore` from
`https://git.eeqj.de/sneak/prompts/raw/branch/main/.dockerignore` and extend
it with the repo's own artifacts.
- **In-repo agent scratch belongs in both files, written to each file's own
semantics.** `.claude/` holds one worktree per in-flight agent — an entire
additional checkout of the repo — so under `COPY . .` the build context
inflates by a multiple of the repo and another session's unreviewed work can
be copied into an image layer. In `.gitignore` the entry is `.claude/`,
unanchored. In `.dockerignore` it is `.claude`, anchored and with **no** `**/`
prefix, because the prefixed form would also delete any nested directory of
that name from the build. Anchoring carries a known gap that the canonical
`.dockerignore` states in its own comment, since consuming repos receive the
file and not the tracker: the directory is created in the agent's working
directory, so a repo running agents in subdirectories still ships
`services/api/.claude/` and must add its own anchored entry there.
- **A plain `docker build .` of a clone stamps the version that
`git describe --tags --always` gives**, derived from the `.git` in the build
context as the canonical `Dockerfile` above shows. Without its failure check,
a missing `git` or an unreadable checkout would leave `-X main.Version=` empty
and the build would still exit 0. `script/docker` and `script/cibuild` pass
the version they compute on the host; it takes precedence. They do this
byte-identically across repos:
```sh
# Own line: a failing command substitution inside an argument does not
# trip `set -e`, so the inline form degrades to an empty constant.
version="$(git describe --tags --always --dirty 2>/dev/null || true)"
[ -n "$version" ] || version="unknown"
docker build --no-cache \
--build-arg VERSION="$version" \
-t "$(script/projectname)" .
```
`--always` makes an untagged repo yield an abbreviated commit hash rather
than failing, and the `[ -n "$version" ]` line is the single place the
fallback is applied — a live check that fires on a build from an export with
no `.git` and on a repository with no commits yet. Do not fold it into the
substitution as `|| echo unknown`, which makes the guard unreachable. The
Dockerfile's side is `ARG VERSION` in the stage that compiles, declared
there because `ARG` is stage-scoped; passing `VERSION` to a repo whose
Dockerfile declares no such `ARG` is ignored and costs nothing, which is why
the scripts stay byte-identical. One consequence for CI: the standard
checkout action clones shallow and fetches no tags, so a repo that embeds a
tag-derived version must set `fetch-depth: 0` on its checkout step.

- compares the installed version against the pin over the **whole** version

running `2.12.2-rc1` and skips the install;
- treats absent, non-zero, empty or unrecognised `--version` output as a
mismatch, so the failure direction is a redundant install and never a

- Guidance for coding agents lives in one `AGENTS.md` at the repository root. It
is never committed under a file or directory named after one agent tool, such
as `CLAUDE.md` or `.claude/`, and never split into separate memory files.

# Completed Steps
- 2026-10-07: The canonical files are re-vendored from `sneak/prompts` commit
`dd4027b` (https://git.eeqj.de/sneak/secret/issues/121), with golangci-lint
v2.14.0 in the lint phase. Lint and test are phases of the `Dockerfile`, and
`script/lint` and `script/test` each build one with `--no-cache`;
`Dockerfile.lint` and `script/lint-darwin` are gone, and the lint phase also
checks the macOS build. The tests run on the Debian Go image with cgo and the
race detector. `script/cibuild` bootstraps, runs `script/check` and builds the
image; `CHECK_EPOCH` and the memlock ulimit are gone. `--no-cache` starts Go's
build cache mount empty, so `make test` compiles everything on every run. The
rules in `CLAUDE.md` that `AGENTS.md` lacked are in `AGENTS.md`, and
`CLAUDE.md` is deleted.
- 2026-10-06: `script/test` runs the tests with the race detector, a 30-second
timeout per package and coverage, as `REPO_POLICIES.md` requires
(https://git.eeqj.de/sneak/secret/issues/32). When they fail, it reruns them

# checks out and runs this and nothing else, and script/fmt-check runs
# the formatter on the host, which a pristine checkout cannot do.
