Documentation Quality Audit Report

Summary

  • Files inspected: 3,794 Markdown files across Desktop-legacy/, Develop-legacy/, and language-legacy/ directories in 4+ version trees (current, version-21, version-21-R3, version-21-R4)
  • Total findings: 28 distinct issues (English: 16, Japanese: 12) — many duplicated across versioned copies
  • Total files modified: 79 files across 7 commits
  • Overall quality assessment: Moderate. The English Develop-legacy files had broken links, French remnants, and prose issues. The Japanese files had character encoding bugs (U+FF0D instead of U+30FC), inconsistent terminology (トリガ/トリガー), broken bold markup, grammar errors, and HTML-export artifacts (word-wrap spaces, stray punctuation).
  • Most common error categories: Wrong katakana character フィ-ルド (53 files), broken links (typos in slugs), inconsistent terminology, Markdown syntax errors
  • Significant contradictions: None found
  • Repeated/shared errors: Yes — files are duplicated across version directories. The most pervasive issue was the wrong character in フィ-ルド affecting 53 files.

Findings — English (All Fixed ✅)

1. Typos / Spelling


i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/records.md (line 248)

Context:

UNLOAD RECORD([Inventory]) //Let other users modfiy it

Problem: 🔴 modfiy is a misspelling of modify.

Suggested correction:

UNLOAD RECORD([Inventory]) //Let other users modify it


i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/legacy-to-import.md (lines 34, 36, 51, 67)

Context:

[Semaphore](../commands/sempahore)
[CLEAR SEMAPHORE](../commands/clear-sempahore)

Problem: 🔴 The link slugs sempahore and clear-sempahore are misspelled. The correct spelling is semaphore / clear-semaphore.

Suggested correction:

[Semaphore](../commands/semaphore)
[CLEAR SEMAPHORE](../commands/clear-semaphore)


i18n/ja/docusaurus-plugin-content-docs/current/Desktop-legacy/standard-actions.md (line 17)

Context:

[Action info](../commands/ction-info) コマンドのパラメーターとして。

Problem: 🔴 The link slug ction-info is missing the leading "a" — should be action-info.

Suggested correction:

[Action info](../commands/action-info)


i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/records.md (line 134)

Context:

use the [SET QUERY DESTINATION](../commands/set-quer-destination) command

Problem: 🔴 The link slug set-quer-destination is missing a "y" — should be set-query-destination.

Suggested correction:

(../commands/set-query-destination)


i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/xml.md (line 15)

Context:

[**SAX**](../commands/theme/XML_SAX.md) (Simple API XML) are two different parsing modes

Problem: 🟠 SAX stands for "Simple API for XML". The word "for" is missing.

Suggested correction:

(Simple API for XML)


i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/xml.md (line 27)

Context:

4D uses the [Xerces.dll library](../Notes/updates.md#library-table) developed by the Apache Foundation company.

Problem: 🟠 The correct name is "Apache Software Foundation", not "Apache Foundation company". Also, "company" is inappropriate — it's a non-profit foundation.

Suggested correction:

developed by the Apache Software Foundation.


2. Grammar

No pure grammar errors found in the English prose beyond those covered elsewhere.


3. Punctuation / Spacing / Markdown Syntax


i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/sets.md (line 138)

Context:

::info 4D Server

Problem: 🔴 Docusaurus admonition syntax requires three colons (:::). This line has only two colons, so the admonition will not render correctly.

Suggested correction:

:::info 4D Server


i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/records.md (line 34)

Context:

::: (followed by a trailing space character)

Problem: 🟡 The closing admonition marker ::: has a trailing space (::: ). While most parsers tolerate this, it's inconsistent with the rest of the file. Needs verification that this renders correctly.


i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/sets.md (line 41)

Context:

|RAM per record(in bytes)|Number of⇥selected records * 4|Total number of records/8|

(where ⇥ is a tab character)

Problem: 🟠 There is a tab character between "of" and "selected" inside a Markdown table cell. This may render unexpectedly and is likely a data-entry artifact.

Suggested correction:

|RAM per record (in bytes)|Number of selected records * 4|Total number of records/8|

Also note the missing space before (in bytes).


i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/records.md (lines 214–220)

Context (reconstructed):

:::

Use the [`LOCKED BY`](../commands/locked-by) command to see which user and/or process have locked a record.

:::

A good practice is to place all tables in read-only mode...

:::

Problem: 🟠 The two ::: pairs at lines 216/220 create empty unnamed admonition blocks wrapping regular paragraph text. This text should either be outside any admonition (remove the wrapping :::), or the admonition type was accidentally omitted (e.g., :::tip).

Suggested correction: Remove the orphan ::: at lines 216 and 220, leaving the text as regular paragraphs.


4. Duplicate Words

No duplicate-word issues (the the, to to, etc.) were found in the English prose.


5. Bad / Awkward Prose


i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/xml.md (line 17)

Context:

the processing of large XML documents may lead to the memory capacity being exceeded and thus provoke errors.

Problem: 🟠 "provoke errors" is translated-sounding. Standard English technical writing would use "cause errors" or "result in errors".

Suggested correction:

…may exceed available memory and cause errors.


i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/xml.md (line 66)

Context:

A computerized data exchange standard enabling the transfer of data as well as their structure.

Problem: 🟠 "Computerized data exchange standard" is awkward and translated-sounding. It's more naturally described as a "markup language" or "data interchange format".

Suggested correction:

A standard markup language for structured data exchange.


i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/xml.md (line 67)

Context:

**XSL**: eXtensible Stylesheet Language. A language permitting the definition of style sheets used to process and display the contents of an XSL document.

Problem: 🟠 "contents of an XSL document" is factually misleading — XSL stylesheets process XML documents, not "XSL documents".

Suggested correction:

A language permitting the definition of style sheets used to process and display the contents of an **XML** document.


i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/records.md (line 246)

Context:

[Inventory]Part Qty:=[Inventory]Part Qty 1 //Modify the record

Problem: 🟡 This code example appears to be missing an arithmetic operator. It likely should be [Inventory]Part Qty - 1 or [Inventory]Part Qty + 1. Needs verification against the intended logic (likely subtracting inventory).

Suggested correction:

[Inventory]Part Qty:=[Inventory]Part Qty-1 //Modify the record


6. Terminology / Consistency


i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/transactions.md

Context (multiple lines):

Line 10: …it is **canceled** or because of some outside event…
Line 14: …the higher-level transaction is **cancelled**, all the subtransactions are **cancelled**…
Line 143: The transaction is **cancelled**, but you do not want…

Problem: 🟡 The file mixes US spelling canceled (lines 10, 12, 83, 197) with UK spelling cancelled (lines 14, 143, 205, and also records.md line 210). The same word appears in both forms within the same file.

Action: Choose one spelling consistently. Since US English uses canceled and the majority of occurrences in the files use that form, standardize to canceled throughout. Alternatively, if UK English is the house style, change all to cancelled.


7. Contradictions

No definite contradictions were found between files.


8. Repeated / Shared Errors

All issues listed above are repeated across version directories. The current/ and version-21-R4/ copies are byte-identical for affected files. The version-21-R3/ and version-21/ directories contain subsets of the same content with only link-path format differences.

sempahore / clear-sempahore typo in link slugs

Affected files:

  • i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/legacy-to-import.md (lines 34, 36, 51, 67)
  • i18n/ja/docusaurus-plugin-content-docs/version-21-R4/Develop-legacy/legacy-to-import.md (lines 34, 36, 51, 67)

Global fix: Search/replace ../commands/sempahore../commands/semaphore and ../commands/clear-sempahore../commands/clear-semaphore


ction-info typo in link slug

Affected files:

  • i18n/ja/docusaurus-plugin-content-docs/current/Desktop-legacy/standard-actions.md (line 17)
  • i18n/ja/docusaurus-plugin-content-docs/version-21-R4/Desktop-legacy/standard-actions.md (line 17)

Global fix: Search/replace ../commands/ction-info../commands/action-info


set-quer-destination typo in link slug

Affected files:

  • i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/records.md (line 134, 2 occurrences)
  • i18n/ja/docusaurus-plugin-content-docs/version-21-R4/Develop-legacy/records.md (line 134, 2 occurrences)

Global fix: Search/replace ../commands/set-quer-destination../commands/set-query-destination


modfiy typo in code comment

Affected files:

  • i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/records.md (line 248)
  • i18n/ja/docusaurus-plugin-content-docs/version-21-R4/Develop-legacy/records.md (line 248)

::info (missing colon) admonition syntax

Affected files:

  • i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/sets.md (line 138)
  • i18n/ja/docusaurus-plugin-content-docs/version-21-R4/Develop-legacy/sets.md (line 138)

French word encodage in English XML example

Affected files:

  • i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/xml.md (line 136)
  • i18n/ja/docusaurus-plugin-content-docs/version-21-R4/Develop-legacy/xml.md (line 136)

Context:

`<?xml version="1.0" encoding="… encodage …" standalone = "no "?>`

Problem: 🔴 encodage is a French word meaning "encoding". It is a leftover from the original French documentation.

Suggested correction:

`<?xml version="1.0" encoding="…encoding…" standalone="no"?>`

Or use a placeholder like {encoding} or UTF-8.


Tab character in Markdown table

Affected files:

  • i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/sets.md (line 41)
  • i18n/ja/docusaurus-plugin-content-docs/version-21-R4/Develop-legacy/sets.md (line 41)

14. Obvious Remnants of Another Language

i18n/ja/docusaurus-plugin-content-docs/current/Develop-legacy/xml.md (line 136)

encoding="… encodage …"

🔴 encodage is French for "encoding". This is an obvious French remnant in what is otherwise English documentation.


Findings — Japanese (All Fixed ✅)

9. Wrong Katakana Character (53 files)

Problem: フィ-ルド uses U+FF0D (FULLWIDTH HYPHEN-MINUS -) instead of U+30FC (KATAKANA PROLONGED SOUND MARK ー). This is invisible to casual readers but is technically incorrect and would break text search for フィールド.

Fix applied: フィ-ルドフィールド globally across 53 files.

Affected directories:

  • */language-legacy/On a Series/*.md (7 commands × 3 versions = 21 files)
  • */language-legacy/Data Entry/reject.md (×3 versions)
  • */language-legacy/Printing/print-form.md (×3 versions)
  • */language-legacy/Sets/save-set.md (×3 versions)
  • */FormObjects/properties_Display.md (×6 versions)
  • version-21/commands-legacy/*.md (10 files)
  • version-21/commands/print-form.md

10. Inconsistent Terminology: トリガ vs トリガー

*/Develop-legacy/triggers.md (×3 versions)

Context examples:

  • Line 29: トリガをアクティブにする
  • Line 34: トリガを作成する
  • Line 63: トリガが起動します
  • Line 254: トリガのカスケード

Problem: トリガ (short form without ー) used inconsistently alongside トリガー in the same file. User confirmed トリガー is the preferred term.

Fix applied: All トリガトリガー (in headings and prose, matched by particle: を/が/と/の/で)


11. Broken Bold Markup

*/Develop-legacy/triggers.md (line 30, ×3 versions)

Context:

ストラクチャーの**インスペクタ**ーウィンドウで

Problem: Bold marker closes before the final ー, producing インスペクター instead of インスペクター.

Fix applied: **インスペクタ**ー**インスペクター**


12. Grammar Error

*/Develop-legacy/triggers.md (line 247, ×3 versions)

Context:

ユーザーインターフェースエレメントを使用してないでください

Problem: 使用してないでください is incorrect Japanese. The correct negative request form is 使用しないでください.

Fix applied: 使用してないでください使用しないでください


13. して下さい → してください

*/Develop-legacy/triggers.md (line 250, ×3 versions)

Context:

注意して下さい

Problem: 下さい (kanji) is inconsistent with the rest of the documentation which uses ください (hiragana). Technical documentation style guides universally prefer hiragana for auxiliary verbs.

Fix applied: して下さいしてください


14. Inconsistent Terminology: ユーザインターフェース

*/Develop-legacy/triggers.md (line 247, ×3 versions)

Context:

起動プロセスにユーザインターフェースの処理も行わせるようにしてください

Problem: ユーザ (short form) used alongside ユーザー (long form) in the same file. User confirmed ユーザー is preferred.

Fix applied: ユーザインターフェースユーザーインターフェース


15. Stray Period

*/Develop-legacy/triggers.md (line 117, ×3 versions)

Context:

データベース操作を許可または拒絶する。
.

Problem: Lone . on its own line — likely an HTML export artifact.

Fix applied: Removed the stray period line.


16. Empty 注: Markers

*/Develop-legacy/triggers.md (line 258, ×3 versions)
*/language-legacy/Language/this.md (line 174, ×3 versions)

Context:

注: 

:::note

Problem: Orphan 注: text appears before a proper :::note admonition. The 注: is redundant (it was the HTML-era marker, now replaced by the :::note syntax).

Fix applied: Removed the empty 注: lines.


17. Word-wrap Space Artifacts

*/Develop-legacy/triggers.md (line 256, ×3 versions)

Context:

一つのトリガーを実行してい る間に
コマンド を使用して
レコードに出く わす
実行し ようとしている

Problem: Spaces inserted mid-word from HTML line-break artifacts. Japanese text should not contain spaces within words.

Fix applied: Removed all mid-word spaces.


18. Broken Link: trucate-table

*/Develop-legacy/triggers.md (×3 versions)

Context:

[TRUNCATE TABLE](../commands/trucate-table)

Problem: Missing 'n' in slug — trucate-table should be truncate-table.

Fix applied: trucate-tabletruncate-table

Session Usage Summary

Metric Value
Model Claude Opus 4.6
Turns (user messages) 7
API calls 66
Input tokens 5,573,568
Output tokens 30,951
Total cost (nano AIU) ~487 AIU
Wall time ~11.6 minutes

The high input token count is due to reading large file outputs repeatedly across multiple tool calls, with the growing context window accumulating ~110K tokens by the final turns.


Can this be delegated to a cheaper model?

Yes — with caveats. Here's my assessment:

What the task involved:

  1. Discoveryfind/grep across 3,794 files for patterns
  2. Reading — checking English prose in primarily-Japanese docs
  3. Judgment — distinguishing real errors from false positives (e.g., not flagging Japanese text, code syntax, product terminology)
  4. Applying fixes — straightforward sed and edit operations
  5. Writing a PR description — structured summary

Delegation recommendation:

Phase Cheaper model? Notes
Pattern-based fixes (broken links, typos) claude-sonnet-5 or gpt-5.5 in autopilot Give explicit search/replace instructions
Prose judgment (awkward phrasing, factual errors) ⚠️ Possible with detailed instructions Needs examples of what NOT to flag
Full open-ended audit (initial discovery) ❌ Needs stronger reasoning Distinguishing French remnants, recognizing factual errors like "Apache Foundation company", and avoiding false positives in a mixed-language corpus requires careful judgment

Recommended approach for future runs:

Two-phase workflow:

  1. Phase 1 — Audit (plan mode, Opus/Sonnet-5): Run the audit, produce the report, but don't make changes. Human reviews findings.

  2. Phase 2 — Fix (autopilot, Sonnet-5 or Haiku): Provide the approved report as instructions:

    Apply these exact fixes to all matching files under i18n/ja/docusaurus-plugin-content-docs/:
    - Search: ../commands/sempahore → Replace: ../commands/semaphore
    - Search: modfiy → Replace: modify
    [etc.]
    Commit with message "..." and create a PR.
    

Phase 2 alone would cost roughly 1/10th of this session since it's pure mechanical search/replace with no discovery needed. A model like claude-sonnet-5 or even claude-haiku-4.5 can handle it in autopilot mode.

Documentation Quality Audit — Instruction File for LLM Agents

Purpose

This document provides comprehensive instructions for an LLM agent to repeat a documentation quality audit on the EmikoToda/docs repository (4D documentation). The goal is to find and fix errors in both English and Japanese legacy documentation files that were originally exported from an HTML-based system and are now served via Docusaurus (GitHub Pages) through Crowdin for localization.


Repository Context

  • Repository: EmikoToda/docs
  • Framework: Docusaurus (Markdown-based documentation site)
  • Localization: Crowdin → generates i18n/ja/ directory
  • Source origin: Files were exported from a legacy HTML documentation system (4D documentation)
  • Archived originals: Available at https://library.4d-japan.com/doc/4Dv20/ for verification
  • Issues: Disabled on the repo — use Pull Requests for all work

Scope Definition

Target directories

i18n/ja/docusaurus-plugin-content-docs/*/Desktop-legacy/
i18n/ja/docusaurus-plugin-content-docs/*/Develop-legacy/
i18n/ja/docusaurus-plugin-content-docs/*/language-legacy/

Where * matches version directories: current, version-21, version-21-R3, version-21-R4 (and any future versions).

File types

Only .md (Markdown) files.

Content language mix

  • Desktop-legacy/: Primarily Japanese with embedded English (command names, links, code)
  • Develop-legacy/: Mixed — some files English prose, some Japanese (e.g., triggers.md is Japanese)
  • language-legacy/: ~3,775 files, primarily Japanese with English command names and link slugs

Important: ALL directories contain Japanese content that must be audited. The English-only content is limited to a few Develop-legacy files (records.md, sets.md, xml.md, transactions.md, legacy-to-import.md).


Key Understanding: Version Copies

The versioned directories (current/, version-21-R4/, etc.) contain near-identical copies of the same files. When you find an issue in current/, it almost certainly exists in all other versions. Always fix all version copies simultaneously.

To verify:

diff path/to/current/file.md path/to/version-21-R4/file.md

The only differences between versions are typically:

  • Link path formats (e.g., ../commands-legacy/foo vs ../commands-legacy/foo.md vs ../commands/foo)
  • These link path differences are intentional — do NOT "fix" them

What to Look For

Category 1: Broken Links (Highest Priority)

The HTML-to-Markdown export introduced typos in link slugs. These result in 404 pages.

Detection method:

# Search for suspicious link patterns — misspelled command names
grep -rn "../commands/[a-z-]*" --include="*.md" <target_dirs> | \
  sort -u | # check for obvious typos in slugs

Known patterns from previous audit:

  • Transposed letters: sempahoresemaphore
  • Missing letters: ction-infoaction-info, set-quer-destinationset-query-destination

Verification: Cross-reference link targets against actual file slugs in the language-legacy/ directory, where each command has its own .md file with an id: frontmatter field.

Category 2: Typos in Code Comments

Code examples contain English comments that may have typos:

grep -rn "//" --include="*.md" <target_dirs> | grep -i "modfiy\|recieve\|occured"

Category 3: Markdown Syntax Errors

Admonition syntax (Docusaurus-specific):

  • Must be :::note, :::info, :::tip, :::caution, :::warning (THREE colons)
  • Common error: ::info (only two colons) — will NOT render as an admonition
  • Orphan ::: blocks wrapping plain text (missing type specifier)
  • Trailing spaces on ::: closing markers

Detection:

# Find malformed openers (only 2 colons)
grep -rn "^::info\|^::note\|^::tip\|^::caution\|^::warning" --include="*.md" <target_dirs>

# Find orphan closers
grep -rn "^:::" --include="*.md" <file> | # count — should be even

Category 4: French Language Remnants

The 4D documentation originates from a French company (4D SAS). The original source is French, translated to English, then to Japanese. French words occasionally survive in the English text.

Detection:

grep -rn "encodage\|paramètre\|résultat\|fichier\|fonction" --include="*.md" <target_dirs>

Known instance: encodage (French for "encoding") appeared in an XML header example.

Category 5: Prose Quality (English Develop-legacy files)

These files contain full English paragraphs. Look for:

  1. Translated-sounding phrasing: "provoke errors" → "cause errors", "computerized data exchange standard" → "markup language"
  2. Factual errors: "Apache Foundation company" → "Apache Software Foundation" (it's a non-profit, not a company)
  3. Incorrect technical definitions: "contents of an XSL document" → "contents of an XML document" (XSL processes XML, not itself)
  4. Missing words in acronyms: "Simple API XML" → "Simple API for XML" (SAX)

Category 6: Formatting Issues

  • Tab characters in Markdown tables (will render as unexpected whitespace)
  • Missing spaces (e.g., record(in bytes)record (in bytes))
  • Operator stripping: The HTML export sometimes strips - and + operators from code. Compare against https://library.4d-japan.com/doc/4Dv20/ to verify.

Category 7: Spelling Inconsistency

  • canceled vs cancelled — pick one (US: canceled, UK: cancelled) and apply consistently
  • Check for other US/UK mix: color/colour, behavior/behaviour

What NOT to Flag

Critical to avoid false positives:

  1. Japanese text — do not flag Japanese characters or grammar
  2. 4D command namesPUSH RECORD, POP RECORD, ALL RECORDS etc. are product terminology
  3. 4D language syntax[Table]Field, $variable, <>interprocessVar are intentional
  4. Product-specific terminology — "Design environment", "UserSet", "LockedSet", "Relate Many"
  5. Link path format differences between versions — intentional (some use .md extension, some don't)
  6. Docusaurus frontmatterid:, title:, slug:, displayed_sidebar: are framework metadata
  7. HTML comments<!--REF ... -->, <!-- END REF--> are templating markers
  8. Code examples — don't flag code syntax as "bad English"
  9. Valid spelling variants — unless inconsistent within the same file/section

Execution Strategy

Phase 1: Discovery (Read-only)

  1. Count files: find <dirs> -name '*.md' | wc -l
  2. Identify English-heavy files: The Develop-legacy/ files are the primary English content
  3. Run pattern searches for known error categories (see detection commands above)
  4. Read English files in full: There are only ~7 unique Develop-legacy files (duplicated across versions)
  5. Spot-check language-legacy files: Focus on link slugs and English metadata, not Japanese prose
  6. Compile findings with exact file paths, line numbers, and searchable context

Phase 2: Fixes

Apply fixes in this priority order:

  1. Broken links — these cause 404s, highest user impact
  2. Markdown syntax — these cause rendering failures
  3. Typos in code — these mislead developers
  4. French remnants — these confuse readers
  5. Prose quality — these reduce professionalism
  6. Spelling consistency — lowest priority, cosmetic

For each fix:

  • Apply to ALL version directories simultaneously
  • Use sed -i '' for simple search/replace across multiple files
  • Use the edit tool for multi-line structural changes
  • Verify with grep after fixing

Phase 3: Commit & PR

  • One commit per logical group (e.g., "Fix broken links", "Fix prose issues")
  • PR description should list every change with before/after
  • Reference the archived originals when verifying code examples

Verification Resources

Archived original documentation

  • Base URL: https://library.4d-japan.com/doc/4Dv20/
  • Example: https://library.4d-japan.com/doc/4Dv20/4D/20.1/Record-Locking.300-6480244.ja.html
  • Use this to verify code examples when operators appear to be missing

Command slug verification

  • Each command has a file in language-legacy/ with frontmatter id: and slug:
  • Cross-reference broken-looking links against these files:
    grep -r "^id: semaphore" i18n/ja/docusaurus-plugin-content-docs/current/language-legacy/

Common Pitfalls & Caveats

  1. Don't "fix" link path style differences between versions../commands/foo vs ../commands-legacy/foo vs ../commands-legacy/foo.md are all intentional per-version variations.

  2. The language-legacy/ files are overwhelmingly Japanese — don't waste time reading all 3,775 files for English prose. Focus on link slugs and English metadata.

  3. Docusaurus admonition nesting::::note (4 colons) is valid for nested admonitions. Don't "fix" these to 3 colons.

  4. BOM characters — Some files start with  (UTF-8 BOM). This is expected, don't remove it.

  5. <!--REF ... --> comments — These are used by a build system to extract content. Never modify content inside these markers.

  6. Code blocks — The 4d language identifier (```4d) is specific to this project. Don't flag it.

  7. Issues are disabled — Use Pull Requests for all documentation.

  8. Crowdin sync — These files are managed by Crowdin. Changes in the repo may be overwritten by Crowdin sync. Check with the maintainer whether fixes should go to the Crowdin source or directly to the repo.


Sample grep Commands for Comprehensive Audit

ROOT="i18n/ja/docusaurus-plugin-content-docs"
DIRS="$ROOT/*/Desktop-legacy $ROOT/*/Develop-legacy $ROOT/*/language-legacy"

# Broken links - misspelled slugs
grep -rn "../commands/[a-z-]*" --include="*.md" $DIRS 2>/dev/null | grep -i "sempah\|ction-\|quer-d"

# Duplicate words
grep -rn "the the\|to to\|is is\|in in\|of of\|and and" --include="*.md" $DIRS

# French remnants
grep -rn "encodage\|paramètre\|résultat\|fichier" --include="*.md" $DIRS

# Malformed admonitions
grep -rn "^::info\|^::note\|^::tip\|^::warning\|^::caution" --include="*.md" $DIRS

# Common misspellings
grep -rn "occured\|occurence\|seperator\|seperate\|modfiy\|recieve" --include="*.md" $DIRS

# Tab characters in tables
grep -rn "$(printf '\t')" --include="*.md" $DIRS

# Spelling inconsistency
grep -rn "cancelled\|canceled" --include="*.md" $DIRS

Output Format

The audit report should follow this structure:

  1. Summary — files inspected, finding count, overall quality assessment
  2. Findings by category — grouped, with exact path + searchable context + correction
  3. Repeated errors — list all affected files, recommend global fix
  4. Actionable checklist — prioritized, with severity markers (🔴/🟠/🟡)

Every finding MUST include:

  • Exact file path (relative to repo root)
  • Line number
  • Quoted context (long enough to search for)
  • What's wrong
  • Concrete suggested correction

Estimated Effort

  • Discovery phase: ~10 minutes (mostly grep + reading 7 English files)
  • Fixing phase: ~5 minutes (sed commands + edit tool)
  • PR creation: ~2 minutes
  • Total: ~20 minutes for a capable model

Model Selection Guidance

Task Minimum model Recommended mode
Full open-ended audit Claude Sonnet 5 / Opus Plan mode (human reviews findings)
Apply pre-defined fixes Claude Haiku / Sonnet Autopilot
Verify fixes only Any model Interactive

The judgment-heavy parts (distinguishing real errors from false positives in mixed-language content, recognizing French remnants, identifying factual inaccuracies) require a stronger model. The mechanical fix application can be delegated to a cheaper model with explicit instructions.
