Codex Translator

Translation via the codex plugin companion script, reviewed and finalized by Claude Code.

Codex Plugin Companion Script

The codex plugin provides a companion script for running tasks. Resolve it dynamically:

CODEX_PLUGIN_ROOT=$(command ls -d "$HOME/.claude/plugins/cache/openai-codex/codex"/*/ 2>/dev/null | sort -V | tail -1)
CODEX_COMPANION="${CODEX_PLUGIN_ROOT}scripts/codex-companion.mjs"

If the file does not exist, report "Codex plugin not installed. Run /codex:setup first." and fall back to Claude Code translation.

Usage for translation tasks:

node "$CODEX_COMPANION" task "<translation prompt>"

The task command runs Codex in read-only mode by default (no --write flag).

Process

Step 0: Pre-flight Rate Limit Check

Before doing anything, check if Codex is currently rate-limited:

RATE_CHECK=$(node $HOME/.claude/scripts/codex-rate-limit.js check 2>&1)
RATE_EXIT=$?

If RATE_EXIT is non-zero (rate-limited), skip all codex steps and jump directly to the Fallback step. Do NOT report the rate limit to the user — silently fall back.

Step 1: Understand the Translation Task

• Source language and target language
• Source text (inline, file path, or selection)
• Context (technical docs, UI strings, blog post, etc.)
• Tone preferences (formal, casual, technical)

Step 2: Build Translation Prompt

Translate the following text from <source-lang> to <target-lang>.

Context: <what the text is for — technical documentation, UI, blog, etc.>
Tone: <formal/casual/technical>

Rules:
- Preserve technical terms and code references as-is
- Maintain formatting (markdown, HTML tags, etc.)
- Preserve line breaks and paragraph structure
- Use natural phrasing in the target language

Text to translate:
---
<source text>
---

If translating a file, include the file content in the prompt.

Step 3: Run Codex

LOGDIR=$(node $HOME/.claude/scripts/get-logdir.js)
mkdir -p "$LOGDIR"
DATETIME=$(date +%Y%m%d_%H%M%S)

# Resolve codex companion script
CODEX_PLUGIN_ROOT=$(command ls -d "$HOME/.claude/plugins/cache/openai-codex/codex"/*/ 2>/dev/null | sort -V | tail -1)
CODEX_COMPANION="${CODEX_PLUGIN_ROOT}scripts/codex-companion.mjs"

# Detect timeout command (gtimeout on macOS via coreutils, timeout on Linux/WSL)
if command -v gtimeout &>/dev/null; then
  TIMEOUT_CMD="gtimeout"
elif command -v timeout &>/dev/null; then
  TIMEOUT_CMD="timeout"
else
  TIMEOUT_CMD=""
  echo "WARNING: neither gtimeout nor timeout found. Running without timeout."
fi

${TIMEOUT_CMD:+$TIMEOUT_CMD} ${TIMEOUT_CMD:+1500} node "$CODEX_COMPANION" task \
  "<translation prompt>" \
  > "$LOGDIR/${DATETIME}-codex-translation-draft.md" \
  2>"$LOGDIR/${DATETIME}-codex-translation-draft-stderr.log"

Timeout: 25 minutes.

Step 4: Check for Rate Limiting

After codex completes (or times out), check output files for rate limit errors:

node $HOME/.claude/scripts/codex-rate-limit.js check-output \
  "$LOGDIR/${DATETIME}-codex-translation-draft.md" \
  "$LOGDIR/${DATETIME}-codex-translation-draft-stderr.log"

If exit code is non-zero (rate limit detected), jump to Fallback.

Step 5: Fallback — Opus

If codex times out, produces no output, or is rate-limited:

• Silently fall back to Opus — do NOT report the rate limit or timeout to the user. Do NOT pause the workflow.
• Spawn a text-fixer subagent (or general-purpose subagent) with model: opus to perform the translation. Opus is the designated Claude-side stand-in for codex throughout these skills.
• Continue the workflow as if the subagent translation was the original plan

Step 6: Review and Finalize

1. Read codex output from the log file
2. Review translation quality:

• Natural phrasing in target language
• Technical accuracy
• Formatting preservation
• No omissions or additions

3. Fix any issues
4. Write the final translated content to the target file via Claude Code

Important: Claude Code does all file writing. Codex only drafts.

Step 7: Report

Present the translation to the user. Include the draft log path.

Timeout Policy

• Timeout: 25 minutes (1500s)
• If codex times out: Silently fall back to Opus (subagent at model: opus)
• Codex runs read-only — cannot modify files

Important Notes

• Codex provides the initial translation draft
• Claude Code reviews for quality and handles file operations
• For large translations (entire files), read the file content and include it in the prompt
• Supports any language pair — specify source and target explicitly
• Silent fallback policy: If codex is rate-limited, timed out, or unavailable, silently fall back to a subagent at model: opus (text-fixer or general-purpose). NEVER pause the workflow, NEVER report the rate limit to the user, NEVER ask what to do. Opus is the designated Claude-side stand-in for codex throughout these skills
