In .pre-commit-config.yaml around line 72, the cspell pre-commit entry is noisy
and slow; update the entry to run cspell with quiet/no-progress and caching by
adding the flags --no-progress and --cache to the command (e.g. cspell --config
./cspell/cspell.json --no-progress --cache) so CI is faster and less verbose,
and add .cspellcache to .gitignore (if not already present) to avoid committing
the cache file.

In .pre-commit-config.yaml at line 73, the files regex only covers common
text/code extensions and omits scripts and build files; update the pattern to
also match shell and scripting extensions and common build filenames (e.g., add
\.(sh|bash|zsh|ps1|gradle|mk)$ and include literal filenames like ^Dockerfile$
and ^Makefile$ or their variants) so the spellcheck hook runs on scripts and
build files too; modify the files entry to combine the existing extensions with
these additional patterns (using alternation or a second hook entry) ensuring
YAML syntax and proper escaping.

In .pre-commit-config.yaml around line 76, the exclude regex uses a trailing $
which matches only the exact directory path and therefore won't exclude files
inside those directories; change the pattern to use a prefix match that ends
with a slash (e.g. remove the trailing $ and ensure the directory list is
followed by /) so the regex excludes any path that begins with those directories
rather than only the directory name itself.

In .pre-commit-config.yaml around lines 78 to 81, the current hook uses a bash
one-liner which will fail on Windows; replace it with a cross-platform tiny
Python script and call that from the hook. Add the script
tools/sort_cspell_dict.py (as described in the review) that reads
cspell/custom-dict.txt, preserves comment lines, strips/filters blank lines,
sorts and deduplicates words while preserving case, and rewrites the file with a
trailing newline; make the script executable and committed. Then update the hook
entry to invoke the script with the system language (e.g., entry: python3
tools/sort_cspell_dict.py or use {python} from pre-commit) and keep files:
^cspell/custom-dict\.txt$ so the hook runs cross-platform.

In make.cmd around lines 21 to 23, the call to cspell\make.cmd is not path-safe;
replace it with a script-dir anchored, quoted path using the batch %~dp0
variable (e.g. call "%~dp0cspell\make.cmd") so the command survives spaces and
symlinks, then keep the existing Exit /B %ERRORLEVEL% unchanged.

In Makefile around lines 1 to 4, the .PHONY declaration only lists spellcheck;
expand it to declare common phony targets so checkmake and quiet (and other
frequently used phony targets) are recognized. Update the .PHONY line to include
spellcheck, checkmake, quiet and any other repository-standard phony targets
such as all, test, clean, etc., ensuring the Makefile consistently declares
every non-file-producing target as phony.

In cspell/cspell.json around lines 13 to 72, the file enables a very large
global dictionary list that increases noise; trim this list to just the language
dictionaries your app actually ships plus shared dictionaries (e.g., keep en-us
or en-gb depending on product locale, and retain essential global lists like
software-terms, makefile, markdown, python, custom-dict), remove all other
locale-specific dictionaries, and document any removed locales in a comment so
contributors can add them back via a per-folder or per-package cspell.json
when/if those locales are introduced.

In cspell/cspell.json around lines 74-79, the cspell "files" array currently
lists only docs and l10n paths while the project help claims scopes "code, docs,
l10n"; update the config to match the advertised scopes by adding code/script
file patterns (for example add src/**/*, **/*.ts, **/*.js, scripts/**/* or other
repo-specific code paths) so cspell runs on code as well as docs and l10n —
alternatively, if you intend to exclude code, update the help text to remove
"code" from the advertised scopes; pick one approach and make the corresponding
change so help and config are consistent.

In cspell/cspell.json around lines 81 to 96, the ignore list is missing common
noisy caches and editor/tool directories which cause false positives and slower
scans; add entries such as ".vscode/**", ".idea/**", ".cache/**", "coverage/**",
"vendor/**", "target/**", ".terraform/**", ".gradle/**", ".bundle/**",
".sass-cache/**", ".DS_Store", ".history/**", ".parcel-cache/**", ".next/**",
"out/**" to the existing array so these directories and files are skipped by the
spellchecker; ensure patterns include /** where appropriate and keep the list
sorted/consistent with existing entries.

In cspell/custom-dict.txt around lines 1 to 1, the header contains a literal
backslash+n sequence ("\\n") instead of an actual newline; remove the backslash
and ensure the line ends with a real newline character so the header reads "#
Project-specific terms" followed by a normal newline.

In cspell/make.cmd around lines 37 to 42, the script currently always runs the
docker cspell lint step even if :cspell-install or :cspell-run failed; update
the script so failures propagate and stop the pipeline by checking the exit
status after each call and exiting early on non-zero. After calling
:cspell-install and :cspell-run, test ERRORLEVEL (or use CMD's || operator) and
if non-zero call exit /b %ERRORLEVEL% (or goto end with an error), so the docker
run is skipped when either prior step fails and the process returns the original
failure code.

In cspell/package.json around lines 65–66 the cspell dependency is specified as
"^8.19.4", which mismatches the unpinned cspell usage in
.pre-commit-config.yaml; fix by making both use the identical exact version:
either remove the caret in cspell/package.json to pin "8.19.4" exactly, or
update .pre-commit-config.yaml to reference the same explicit cspell
revision/version (8.19.4); ensure both files are updated so they match exactly
and run a quick install or pre-commit check to verify consistency.

In Makefile around line 14, the help text for the "spellcheck" target claims it
runs across "code, docs, l10n" but does not match cspell.json's actual "files"
configuration; update the Makefile help text to exactly mirror the glob list or
named scopes from cspell.json, or alternatively modify cspell.json to include
docs and l10n paths so the help text is correct—ensure the phrasing and scope in
the echo string precisely reflect the cspell "files" entries so users see
accurate help output.

In Makefile around lines 28-31, the spellcheck target should be updated to
enable caching for faster repeated runs: modify the docker invocation used by
cspell-check to mount a host cache directory (and the .cspellcache file) into
the container as volumes (e.g., map a repo-local .cspellcache and a
.cache/cspell or similar path) so cspell can reuse results across runs, and
update repository ignores to include .cspellcache if not already ignored; ensure
the Makefile preserves the existing docker-not-found check and exits
appropriately when docker is missing.

In tools/sort_cspell_dict.py around lines 10 to 13, the script currently prints
a message and returns when the dictionary file is missing which hides failures
in CI; replace the print + return with a non‑zero exit so the process fails fast
(e.g., import sys at top if not present and call sys.exit(1) with a helpful
message or raise SystemExit(1)); ensure the exit path returns a non‑zero status
so CI/Make detects the error.

In tools/sort_cspell_dict.py around lines 18 to 33, the current code removes
duplicates case-sensitively, keeps blank lines and sorts comments too; change it
to: treat lines starting with '#' as comments and preserve their original order,
drop blank lines entirely, collect non-comment lines as words, dedupe words
case-insensitively while keeping the first-seen original casing, sort the
deduped words using a case-insensitive key, and when writing the file output
preserved comment lines first (in their original order), then a single blank
line (if there were comments) followed by the sorted unique words joined by '\n'
and a final '\n'.
