* Usage: node prepare-claude-prompt.mjs

*
|
|
* Environment variables:
|
|
* INPUT_TASK - The task description (required)
|
|
* USE_RAW_PROMPT - "true" to pass task directly without wrapping
|
|
* GITHUB_ENV - Path to GitHub env file (set by Actions)

# Instructions
|
|
1. Read any relevant templates listed above before starting
|
|
2. Complete the task described above
|
|
3. Make commits as you work - the last commit message will be used as the PR title
|
|
4. IMPORTANT: End every commit message with: Co-authored-by: Claude <noreply@anthropic.com>
|
|
5. Ensure code passes linting and type checks before finishing
|
|
|
|
# Token Optimization
|
|
When running lint/typecheck, suppress verbose output:
|
|
pnpm lint 2>&1 | tail -30
|
|
pnpm typecheck 2>&1 | tail -30`;
|
|
}
|
|
|
|
// Random delimiter guarantees no collision with user content
|
|
const delimiter = `CLAUDE_PROMPT_DELIM_${randomUUID().replace(/-/g, '')}`;
|
|
appendFileSync(envFile, `CLAUDE_PROMPT<<${delimiter}\n${prompt}\n${delimiter}\n`);
