Catch-up from base v0.1.10 before the prek pilot changes, kept as its own commit so the prek diff stays reviewable. Restored the template's custom consumer README and pyright_version context var that the update's rejects dropped; relocked faker.
Pulls the forward-compatible prek migration groundwork from the copier-base-template prek-prep branch while still running pre-commit: seeded .prekignore, prek installed alongside pre-commit, lint-matrix dotfile cleanup with --show-diff-on-failure and a working log artifact name, the sync-dependencies stderr check, pyrefly --frozen, tool-neutral CodeRabbit wording, dual-prefix devcontainer hash detection, and prek run permissions with config-redirection denials. Template-specific follow-up: run the consumer config's pyright-on-tests hook with --frozen for the same reason as pyrefly.

prek 0.5.4 official command line run options config cd directory global option aliases positional placement; Claude Code Bash permission pattern syntax matching shell commands documentation
💡 Result:
## `prek 0.5.4`
The official release page confirms **0.5.4 was released September 28, 2026**. The available CLI reference is the current/dev reference, not explicitly version-pinned to 0.5.4; it lists the following `run` interface, so check `prek run --help` on your installed binary if exact version behavior matters. ([github.com](https://github.com/j178/prek/releases?utm_source=openai))
```text
prek run [OPTIONS] [HOOK|PROJECT]...
```
- **Config:** `--config <CONFIG>` / `-c <CONFIG>` selects an alternate config file.
- **Change directory:** `--cd <DIR>` / `-C <DIR>` changes directory before running. It affects config/workspace discovery; paths for `--files`, `--directory`, and `--glob` resolve from the directory after `--cd`.
- **Options vs positional selectors:** options such as `--config` and `--cd` are flags; `[HOOK|PROJECT]...` are positional selectors and can be repeated. Selectors include a hook ID, `project-path/`, or `project-path:hook-id`. In normal CLI syntax, put selectors after `run`, and options may be placed before or after them, e.g. `prek run -C subdir -c config.toml lint` (verify with the installed version if placement is important).
- **No subcommand:** `prek` alone is equivalent to `prek run`. ([prek.j178.dev](https://prek.j178.dev/reference/cli/?utm_source=openai))
## Claude Code Bash permission patterns
Claude Code’s official permission documentation describes Bash rules as `Bash(...)` patterns: `*` is a wildcard over command text, and rules are evaluated against shell commands. For example, `Bash(git status)` is exact, while `Bash(git *)` is broader. **Be cautious with broad prefixes**: `Bash(git *)` can allow many Git subcommands. Compound commands are handled with shell-operator awareness; allowing one command pattern does not automatically authorize every command chained with `&&`, `|`, or similar operators. ([bacol.todayz.workers.dev](https://bacol.todayz.workers.dev/post-https-code.claude.com/docs/en/permissions?utm_source=openai))
**Practical implication:** a rule intended for `prek run` should be narrowly scoped to the exact command/arguments you want to permit; avoid assuming a broad prefix safely constrains config paths, directory changes, or additional shell commands. The retrieved official Claude page establishes the pattern mechanism, but I couldn’t verify its complete current Bash-pattern examples from the official page in this search. ([bacol.todayz.workers.dev](https://bacol.todayz.workers.dev/post-https-code.claude.com/docs/en/permissions?utm_source=openai))

prek v0.5.4 source run command parser clap options after positional selectors -C --cd --config aliases; official Claude Code permissions Bash deny allow pattern matching precedence and wildcard semantics
💡 Result:
## `prek` v0.5.4: `run` options vs. selectors
I could confirm the v0.5.4 release and its commit (`77c4056`), but couldn’t retrieve the tagged CLI source to verify the exact `clap` parser definition. So I can’t establish from the available source whether `-C`, `--cd`, or `--config` are accepted *after* positional selectors, or whether those spellings are aliases. The release page is the closest version-specific source. ([github.com](https://github.com/j178/prek/releases?utm_source=openai))
## Claude Code Bash permissions
The current official docs say rules are evaluated by category—**deny, then ask, then allow**—not by specificity. A matching deny blocks even if a narrower allow also matches; allow cannot carve an exception out of deny. ([code.claude.com](https://code.claude.com/docs/en/permissions))
For Bash patterns, `*` matches any text, including spaces; without a wildcard, the command must match exactly. A trailing ` *` also matches the bare command (`Bash(ls *)` matches `ls` and `ls -la`), while `Bash(ls*)` can also match `lsof`. ([code.claude.com](https://code.claude.com/docs/en/permissions))
Important limitation: Bash rules match the command text after Claude Code splits compound commands and strips certain wrappers. They are not a security boundary around an executable: for example, `Bash(git push *)` does not match `git -C . push origin main`. Use sandboxing or a `PreToolUse` hook for stronger enforcement.

Extend the prek run deny patterns to cover option placement.
prek 0.5.4 accepts global options after hook selectors. Therefore, prek run lint -c ../config.yaml or prek run lint -C/tmp can match Bash(prek run *) without matching the current deny patterns. This permits an alternate configuration or working directory without a permission prompt. Apply the same correction to the mirrored template.

Pulls prek 0.5.5, which fixes the conflicted stash restore data loss (j178/prek#2801), and skips installing prek when CI=true since CI still runs hooks through pre-commit.
Moves from the prek-prep branch ref to the released tag. Pulls prek installed in CI too (so downstream repos can trial it there), uv 0.12.23, pnpm 12.9.1 and faker 40.41.0. Restored the template's pyright_version context var that the update's reject dropped; relocked faker.
