Fix misleading prek list help text and add prek list-builtins command

Summary

prek list says "List available hooks" but actually lists hooks configured in the current project. This PR fixes the wording and adds a new list-builtins command so users can discover all built-in hooks from the CLI.

Motivation

The list subcommand's help text reads:

$ prek list -h
List available hooks

This is misleading. prek list does not list hooks that are available to use — it lists hooks that are currently configured in the project's .pre-commit-config.yaml. "Available" implies a catalog of all possible hooks (especially builtins), when the actual behavior is scoped to the current config.

How this causes confusion

User runs prek list in Project A, which has a local hook named no-commit-to-main
Output shows .:no-commit-to-main — reads like an "available" hook
User uses id: no-commit-to-main under repo: builtin in Project B
prek run fails: unknown builtin hook id "no-commit-to-main"

The user reasonably assumed prek list was showing hooks they could use anywhere, because the help text says "available."

After this PR

$ prek -h
  list               List hooks configured in the current project
  list-builtins      List all built-in hooks bundled with prek

$ prek list-builtins
check-added-large-files
check-case-conflict
check-executables-have-shebangs
check-json
check-json5
check-merge-conflict
check-symlinks
check-toml
check-xml
check-yaml
detect-private-key
end-of-file-fixer
fix-byte-order-marker
mixed-line-ending
no-commit-to-branch
trailing-whitespace

Verbose mode shows descriptions:

$ prek list-builtins -v
check-added-large-files
  prevents giant files from being committed.

check-case-conflict
  checks for files that would conflict in case-insensitive filesystems
...

JSON output is also supported via --output-format=json.

What changed

crates/prek/src/cli/mod.rs

Fixed List doc comment from "List available hooks" to "List hooks configured in the current project"
Added ListBuiltins(ListBuiltinsArgs) command variant with --output-format option

crates/prek/src/cli/list_builtins.rs (new)

Iterates all BuiltinHooks variants via strum::EnumIter and outputs their ID, name, and description
Supports text (default), verbose, and JSON output formats
Works from any directory — no config file or git repo required

crates/prek/src/hooks/builtin_hooks/mod.rs

Added strum::EnumIter derive to BuiltinHooks enum

crates/prek/src/main.rs

Wired up Command::ListBuiltins dispatch

crates/prek/tests/list_builtins.rs (new)

list_builtins_basic: verifies plain text output lists all 16 builtin hook IDs
list_builtins_verbose: verifies verbose output includes descriptions
list_builtins_json: verifies JSON output structure

docs/cli.md

Auto-regenerated to include the new list-builtins command

Closes #1599

Set a user default for `prek auto-update`, then override it per project when a repository needs a different update cadence. ```toml [auto_update] cooldown_days = 7 ``` ##### Enhancements - Add global auto-update cooldown config ([#2041](j178/prek#2041)) - Add project auto-update cooldown config ([#2044](j178/prek#2044)) - Support `language: dart` ([#1146](j178/prek#1146)) ##### Bug fixes - Pass commit message file to workspace hooks ([#2043](j178/prek#2043)) - Preserve non-UTF8 filenames from git ([#2023](j178/prek#2023)) - ruby: put resolved Ruby's bin dir on `$PATH` for `gem` invocations ([#2021](j178/prek#2021)) ##### Documentation - Update docs with the new logo and icon ([#2025](j178/prek#2025)) - Point schema docs to SchemaStore ([#2039](j178/prek#2039)) ##### Contributors - [@j178](https://github.com/j178) - [@xiaoyanli-lyft](https://github.com/xiaoyanli-lyft) - [@Lutra-Fs](https://github.com/Lutra-Fs) ### [`v0.3.11`](https://github.com/j178/prek/blob/HEAD/CHANGELOG.md#0311) [Compare Source](j178/prek@v0.3.10...v0.3.11) Released on 2026-04-27. ##### Highlights Hook entries now have an explicit `shell` option for shell snippets. Set `shell: sh`, `bash`, `pwsh`, `powershell`, or `cmd` when an entry should be evaluated by that shell; leaving it unset keeps prek's direct argv execution. `prek auto-update` can now filter tag candidates before choosing an update. Both options take glob patterns: use `--include-tag` to only consider matching tag names, and `--exclude-tag` to skip matching tags such as moving tags or prereleases. ##### Enhancements - Add `auto-update --exclude-repo <repo>` to skip repos ([#1983](j178/prek#1983)) - Add `auto-update --exit-code` to exit with non-zero on updates ([#2002](j178/prek#2002)) - Add `auto-update --include-tag <pattern>`/`--exclude-tag <pattern>` to filter tags ([#1984](j178/prek#1984)) - Adds an explicit `shell` hook option for entries that should run as shell source ([#2004](j178/prek#2004)) - Make `--hook-dir` optional for hook-impl ([#1989](j178/prek#1989)) - Skip shim warning when `--script-version` is missing ([#1990](j178/prek#1990)) ##### Bug fixes - Install Ruby executable in gem bin ([#2017](j178/prek#2017)) - Use dedicated Android npm package ([#1982](j178/prek#1982)) - Use stable repo keys without breaking cached clones ([#1995](j178/prek#1995)) ##### Documentation - Explain prek name ([#1980](j178/prek#1980)) - Clarify `pass_filenames` concurrency docs ([#1999](j178/prek#1999)) - Reorganize documentation references ([#2005](j178/prek#2005)) - Clarify hook author manifest env docs ([#1991](j178/prek#1991)) - docs: add Sentry to users list ([#1981](j178/prek#1981)) ##### Contributors - [@j178](https://github.com/j178) ### [`v0.3.10`](https://github.com/j178/prek/blob/HEAD/CHANGELOG.md#0310) [Compare Source](j178/prek@v0.3.9...v0.3.10) Released on 2026-04-21. ##### Enhancements - Disallow rev for non-remote repos in schema ([#1964](j178/prek#1964)) - Hide up-to-date output in non-verbose mode ([#1942](j178/prek#1942)) - Improve merge conflict marker detection ([#1937](j178/prek#1937)) - Keep finished hooks visible ([#1967](j178/prek#1967)) - Preserve frozen comment spacing in auto-update ([#1945](j178/prek#1945)) - Reimplement `@j178/prek` npm package ([#1973](j178/prek#1973)) ##### Bug fixes - Prefer stable Rust toolchains ([#1974](j178/prek#1974)) ##### Documentation - Add `SKILL.md` for prek ([#1950](j178/prek#1950)) - Document `gh skill install j178/prek prek` to install prek skill for agents ([#1951](j178/prek#1951)) - Improve compatibility and migration docs ([#1940](j178/prek#1940)) ##### Other changes - Sync latest identify tags ([#1947](j178/prek#1947)) ##### Contributors - [@github-actions](https://github.com/github-actions) - [@renovate](https://github.com/renovate) - [@j178](https://github.com/j178) ### [`v0.3.9`](https://github.com/j178/prek/blob/HEAD/CHANGELOG.md#039) [Compare Source](j178/prek@v0.3.8...v0.3.9) Released on 2026-04-13. ##### Highlight `prek auto-update` is now stricter about pinned revisions and more useful in CI. It now keeps `rev` and `# frozen:` comments in sync, can detect [impostor commits](https://docs.zizmor.sh/audits/#impostor-commit) when validating pinned SHAs, and lets you use `prek auto-update --check` to fail on both available updates and frozen-ref mismatches without rewriting the config. Examples: ```console $ prek auto-update # updates revs and repairs stale `# frozen:` comments $ prek auto-update --freeze # writes frozen SHAs with matching `# frozen: <tag>` comments $ prek auto-update --check # exits non-zero when updates are available, a `# frozen:` comment is stale, # or a pinned SHA does not belong to the fetched upstream refs ``` ##### Enhancements -

**`prek.toml` is here!** You can now use `prek.toml` as an alternative to `.pre-commit-config.yaml` for configuring prek. `prek.toml` mirrors the structure of `.pre-commit-config.yaml`, but TOML is less error-prone. Your existing `.pre-commit-config.yaml` will continue to work, but for new users and new projects, `prek.toml` may make more sense. If you want to switch, run `prek util yaml-to-toml` to convert YAML configs to `prek.toml`. See [configuration docs](configuration.md) for details. For example, this config: ```yaml repos: - repo: https://github.com/pre-commit/pre-commit-hooks rev: v6.0.0 hooks: - id: check-yaml ``` Can be written as `prek.toml` like this: ```toml [[repos]] repo = "https://github.com/pre-commit/pre-commit-hooks" rev = "v6.0.0" hooks = [ { id = "check-yaml" } ] ``` - **`serde-yaml` has been replaced with `serde-saphyr`** We replaced the long-deprecated `serde-yaml` crate with [`serde-saphyr`](https://crates.io/crates/serde-saphyr) for YAML parsing. It is written in safe Rust and has better error messages, performance, and security. This lets us provide precise location information for configuration parsing errors, which should make it easier to fix config issues. For example, this invalid config: ```yaml repos: - repo: https://github.com/crate-ci/typos hooks: - id: typos ``` Before: ```console $ prek run error: Failed to parse `.pre-commit-config.yaml` caused by: Invalid remote repo: missing field `rev` ``` Now: ```console $ prek run error: Failed to parse `.pre-commit-config.yaml` caused by: error: line 2 column 5: missing field `rev` at line 2, column 5 --> <input>:2:5 | 1 | repos: 2 | - repo: https://github.com/crate-ci/typos | ^ missing field `rev` at line 2, column 5 3 | hooks: 4 | - id: typos | ``` - **`prek util` subcommands** We added a new `prek util` top-level command for miscellaneous utilities that don't fit into other categories. The first two utilities are: - `prek util identify`: shows the identification tags of files that prek uses for file filtering, which can be useful for debugging and writing `types/types_or/exclude_types` filters. - `prek util yaml-to-toml`: converts `.pre-commit-config.yaml` to `prek.toml`. We also moved `prek init-template-dir` under `prek util` for better organization. The old `prek init-template-dir` command is still available (hidden) as an alias for backward compatibility. ##### Enhancements - Add `prek util identify` subcommand ([#1554](j178/prek#1554)) - Add `prek util yaml-to-toml` to convert `.pre-commit-config.yaml` to `prek.toml` ([#1584](j178/prek#1584)) - Detect install source for actionable upgrade hints ([#1540](j178/prek#1540)) - Detect prek installed by the standalone installer ([#1545](j178/prek#1545)) - Implement `serialize_yaml_scalar` using `serde-saphyr` ([#1534](j178/prek#1534)) - Improve max cli arguments length calculation ([#1518](j178/prek#1518)) - Move `identify` and `init-template-dir` under the `prek util` top-level command ([#1574](j178/prek#1574)) - Replace serde-yaml with serde-saphyr (again) ([#1520](j178/prek#1520)) - Show precise location for config parsing error ([#1530](j178/prek#1530)) - Support `Julia` language ([#1519](j178/prek#1519)) - Support `prek.toml` ([#1271](j178/prek#1271)) - Added `PREK_QUIET` environment variable support ([#1513](j178/prek#1513)) - Remove upper bound constraint of uv version ([#1588](j178/prek#1588)) ##### Bug fixes - Do not make the child a session leader ([#1586](j178/prek#1586)) - Fix FilePattern schema to accept plain strings ([#1564](j178/prek#1564)) - Use semver fallback sort when tag timestamps are equal ([#1579](j178/prek#1579)) ##### Documentation - Add `OpenClaw` to the list of users ([#1517](j178/prek#1517)) - Add `cachix/devenv`, `apache/lucene`, `copper-project/copper-rs` as projects using prek ([#1531](j178/prek#1531), [#1514](j178/prek#1514), [#1569](j178/prek#1569)) - Add document about authoring remote hooks ([#1571](j178/prek#1571)) - Add `llms.txt` generation for LLM-friendly documentation ([#1553](j178/prek#1553)) - Document using `--refresh` to pick up `.prekignore` changes ([#1575](j178/prek#1575)) - Fix PowerShell completion instruction syntax ([#1568](j178/prek#1568)) - Update quick start to use `prek.toml` ([#1576](j178/prek#1576)) ##### Other changes - Include `prek.toml` in run hint for config filename ([#1578](j178/prek#1578)) ##### Contributors - [@fatelei](https://github.com/fatelei) - [@domenkozar](https://github.com/domenkozar) - [@makeecat](https://github.com/makeecat) - [@fllesser](https://github.com/fllesser) - [@j178](https://github.com/j178) - [@copilot-swe-agent](https://github.com/copilot-swe-agent) - [@oopscompiled](https://github.com/oopscompiled) - [@rmuir](https://github.com/rmuir) - [@shaanmajid](https://github.com/shaanmajid) </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.
