Re-vendor the canonical files from sneak/prompts at dd4027b (closes #121)

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. Agent guidance
lives in AGENTS.md alone; the tool-specific file is gone.

Model: opus-5-5

-# 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.

-  repos use a multistage build where linting runs in an independent stage based
+  no separate lint file. `script/lint` and `script/test` each build one phase
-  on the `golangci/golangci-lint` image (pinned by hash). This stage runs
+  and nothing else:
-  `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.
 
-    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.**
+  The lint phase is based on the `golangci/golangci-lint` image (pinned by
+  hash), so lint failures surface in seconds rather than after a full compile,

+      `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

+  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)"

+        --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.

 # 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 runs
+  `go vet` and checks the macOS build too. The tests run on the Debian Go image
+  with cgo and the race detector, with the policy's 90-second timeout.
+  `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
+  verbosely for the details and then fails anyway, so a test that fails once and
+  passes on the retry no longer gives a green build. `go vet` still runs first,
+  and every `go test` keeps `-count=1`. The tests that gave the `secret` binary
+  a minute now give it 10 seconds, and the PGP unlocker test's 30-second timer
+  is 10 seconds, so a test that hangs fails with its own message before the
+  package's 30-second timeout ends every test in it.
+- 2026-10-06: `make test` in `script/cibuild` no longer compiles the standard
+  library and every dependency from nothing on every build
+  (https://git.eeqj.de/sneak/secret/issues/124). The `Dockerfile` runs it and
+  `make build` with Go's build cache in a BuildKit cache mount, which docker
+  keeps between builds, so each compiles only what changed since the last build.
+  The mount has an id of its own, so other repositories' builds do not share it.
+  `script/test` passes `-count=1`, so every test runs on every build and no
+  result comes from Go's test cache. A build with an empty cache, such as the
+  first after docker's build cache is cleared, compiles everything in
+  `make test` as before.
+- 2026-10-06: `TestRemoveIgnoresTerminalOnStdout` and
+  `TestRemoveAsksAtTerminalOnStdin` no longer wait until Go's test timeout
+  (https://git.eeqj.de/sneak/secret/issues/126). On Linux, `pty.Open` of
+  `github.com/creack/pty` v1.1.24 passed the address of a local variable to the
+  `ioctl` system call as a plain number, through a function call; when Go moved
+  the goroutine's stack in between, the kernel wrote the terminal's number to
+  the old place, and `pty.Open` opened `/dev/pts/0` instead of the terminal it
+  had created. `secret rm` then wrote to that other terminal, and the test read
+  a terminal no program had open, which never ends. `go.mod` now requires the
+  commit on that library's main branch that passes a pointer instead; no release
+  has it yet. Both tests stop reading the terminal when their one-minute context
+  ends and fail saying so.
+- 2026-10-06: The tests run quickly with the race detector on
+  (https://git.eeqj.de/sneak/secret/issues/120). Most of their time went to
+  deriving keys from passphrases with scrypt, which is slow on purpose. The new
+  `secret.ScryptWorkFactor`, when not zero, replaces age's scrypt work factor
+  when a passphrase encrypts; the tests of `internal/secret`, `internal/vault`
+  and `internal/cli` set it to 1 before any test runs, and the program never
+  sets it; `TestGetCommandOutputsToStdout` checks that the passphrase unlocker
+  the built binary's `secret init` writes names age's work factor, 18.
+  `TestRemovalAsksWithoutHoldingLock` and `TestFailedCommandReleasesLock` no
+  longer run in parallel with other tests: each waits at most 10 seconds for the
+  in-memory lock that every test in the package shares, and other tests'
+  commands held it longer. `TestConcurrentAddsKeepEveryVersion`, which times
+  nothing, and `TestGetCommandOutputsToStdout`, which no longer sets an
+  environment variable its commands do not read, now run in parallel. The
+  `script/cibuild` comment no longer says that tests are skipped without its
+  memlock ulimit.
+- 2026-10-05: No test stores a secret larger than 1 MiB
+  (https://git.eeqj.de/sneak/secret/issues/52). The size tests for `secret add`,
+  `secret import` and the stdin buffer no longer try 2 MB, 10 MB, 99 MB, 100 MB
+  or 101 MB secrets, and nothing tests that a secret over the 100 MB limit is
+  rejected; the limit itself is unchanged. With nothing large left, the size
+  tests no longer skip a case for want of locked memory.
+- 2026-10-05: The Go module path is `sneak.berlin/go/secret`, as
+  `REPO_POLICIES.md` requires, not `git.eeqj.de/sneak/secret`
+  (https://git.eeqj.de/sneak/secret/issues/43). Every import uses it, as do the
+  `-X` flags in `script/build` that stamp the version and commit shown by
+  `secret info`, and the examples in `pkg/agehd/README.md` and
+  `pkg/bip85/README.md`. `go mod tidy` now lists `github.com/dustin/go-humanize`
+  and `github.com/fatih/color`, which `internal/cli` imports, as direct
+  requirements. Code that imported the old path must switch to the new one.
+- 2026-10-04: `make fmt` formats every markdown file with prettier (4-space
+  tabs, `proseWrap: always`) as well as the Go code, and `make fmt-check` checks
+  both, as the model scripts in the `prompts` repo do
+  (https://git.eeqj.de/sneak/secret/issues/110). Prettier is pinned by hash in
+  `package.json` and `yarn.lock`, and `script/bootstrap` installs node, yarn and
+  prettier. The `Dockerfile` lint stage copies node and yarn from a node image
+  pinned by hash and runs `script/bootstrap`, so its `make fmt-check` fails the
+  build on an unformatted markdown file. Every markdown file was formatted once,
+  wording unchanged.
+- 2026-10-04: A mnemonic that cannot be read, in `secret init` and
+  `secret vault create`, gives an error that names the mnemonic only
+  (https://git.eeqj.de/sneak/secret/issues/115). It is read with
+  `secret.ReadMnemonic`, whose every error wraps the new
+  `secret.ErrMnemonicNotRead`; before, it was read with `ReadPassphrase`, so the
+  message said "failed to read mnemonic: failed to read passphrase:" and advised
+  setting `SB_UNLOCK_PASSPHRASE`. Without a terminal it now says "failed to read
+  mnemonic: stdin is not a terminal (piped input or script). Please set the
+  SB_SECRET_MNEMONIC environment variable or run interactively". The passphrase
+  messages no longer repeat "cannot read passphrase" after "failed to read
+  passphrase:", and empty input gives "nothing was entered".
+- 2026-10-04: A failure returns the same error value whichever command hits it
+  (https://git.eeqj.de/sneak/secret/issues/113). `internal/cli` no longer keeps
+  its own copies of `vault.ErrSecretNotFound`, `ErrVaultNotFound`,
+  `ErrVersionNotFound` and `ErrSecretExists`: `secret mv`, `rm`, `decrypt`,
+  `vault import`, `vault remove` and `version list`, `promote` and `rm` wrap the
+  `vault` errors. `errUnsupportedUnlockerType` is removed: `secret unlocker add`
+  gives `errInvalidUnlockerType` for an unknown type, whichever check rejects
+  it. Off macOS, adding a keychain or Secure Enclave unlocker returns the
+  `secret` package's error for it, not an `internal/cli` copy; on macOS, the
+  check that the system is macOS is gone, as it could never fail.
+  `secret vault import` gives `errInvalidMnemonicPhrase` for an invalid
+  mnemonic, as `init` and `vault create` do. `secret generate secret` gives
+  `errLengthTooSmall` for a length below 1 wherever it is checked, and
+  `errUnsupportedSecretType` for `--type mnemonic` too. `secret import` of a
+  file over 100MB wraps `errSecretTooLarge`, as `secret add` returns it.
+  `vault.ErrNilValueBuffer` is replaced by `secret.ErrNilValueBuffer`, which
+  `secret` already returned under another name. Messages are unchanged, except
+  that `secret decrypt` of a missing secret says "not found", as `secret get`
+  does, not "does not exist"; `vault import` of an invalid mnemonic says
+  "invalid BIP39 mnemonic phrase"; `--type mnemonic` says "unsupported type:
+  mnemonic (use 'secret generate mnemonic' instead)"; and a file too large to
+  import says
+  `failed to read secret from file <path>: secret too large: exceeds 100MB limit`.
+  Every error of `secret.ReadPassphrase` wraps `secret.ErrPassphraseNotRead`,
+  which supplies the words "failed to read passphrase" that its callers used to
+  add themselves; so two passphrases that differ now give only "passphrases do
+  not match", the words now follow "failed to read mnemonic:" and "failed to
+  read passphrase confirmation:", and a terminal read error no longer repeats
+  them. A GPG key the keyring does not hold gives `secret.ErrGPGKeyNotFound`,
+  found by gpg's status line for "No public key"; before, the message repeated
+  "failed to resolve GPG key fingerprint" and ended in gpg's exit status. The
+  keychain unlocker returns `errNilDataBuffer` for nil data; this and its test
+  build only on macOS with cgo and were only read. `bip85.ErrPasswordTooShort`
+  and `ErrEncodedTooShort` are removed with their checks: 64 bytes of entropy
+  always give 86 Base64 or 80 Base85 characters, the most a password length may
+  ask for. Tests that matched these errors' text use `errors.Is`.
+- 2026-10-04: Tests check which error a failure returns with `errors.Is`, not by
+  matching words of its message (https://git.eeqj.de/sneak/secret/issues/49).
+  Every exported error that can be returned has a test that the function returns
+  it, and errors wrapping a cause are checked through the wrapping. Checks that
+  still match text, because the error has no exported value the test can name,
+  are listed on the issue.
+- 2026-10-04: When a vault cannot be opened through its current unlocker,
+  because a file the unlocker needs is missing or damaged, its keychain item or
+  Secure Enclave key is gone, or the passphrase is wrong, the error now ends by
+  naming the vault, saying that it still opens with its mnemonic, and that
+  `secret unlocker add passphrase`, run with `SB_SECRET_MNEMONIC` set to it,
+  gives the vault a new unlocker; for a vault that is not the current one, as in
+  `secret move` between vaults, it says to run `secret vault select` first
+  (https://git.eeqj.de/sneak/secret/issues/47). Before, it ended with the bare
+  cause. The advice is given only when the vault metadata records the key the
+  mnemonic derives, so not for a vault created without a mnemonic, and not when
+  the passphrase could not be read at all. `secret vault import` is not named:
+  it refuses a vault that has a long-term key. `secret encrypt` and
+  `secret decrypt` now read the key secret through `vault.GetSecret`, as
+  `secret get` does, so they give the same advice; `Secret.GetValue`, the other
+  way to get the long-term key, is removed. When a secret's `current` file
+  cannot be read, the error says that `secret version list` lists its versions
+  and `secret version promote` makes one current. The causes stay wrapped.
+- 2026-10-04: An unlocker's ID is the name of its directory in `unlockers.d`, so
+  no two unlockers of a vault share one
+  (https://git.eeqj.de/sneak/secret/issues/98). Before, a keychain or Secure
+  Enclave unlocker's ID was its creation time to the minute and the host name,
+  and a passphrase unlocker's the time to the minute, so two created within a
+  minute shared an ID, and `unlocker select`, `unlocker remove` and the
+  selection `unlocker add` makes acted on the older one. A PGP unlocker's ID was
+  `pgp-` and its key's fingerprint; a second PGP unlocker for a key is still
+  refused, now by comparing the fingerprint in the other unlockers' metadata.
+  `unlocker list` and the shell completion of `unlocker select` and
