Use for ALL resume-related actions. action omitted or action=tailor: ONLY when the user wants to improve, optimize, tailor, or rewrite a resume (text optimization). action=generate: MANDATORY when the user asks for generate/create resume, resume template, styled or formatted resume, downloadable resume, PDF resume, or preview/shareable resume — do NOT use tailor for those. INPUT for generate: resume_text or resume_content (plain text or JSON Resume as string), and/or json_resume (JSON Resume object: basics, work[], education[], skills[] per jsonresume.org — preferred for structured data). At least one of those is required. Optional template_key (Workopia registry key; omit defaults to Workopia Classic / workopia_classic). Legacy alias hera_classic accepted. OUTPUT for generate: template_name, url (preview), download_url (PDF) from the tool only — never invent URLs; never return raw PDF/HTML/base64. OUTPUT for tailor differs (e.g. optimizedResume text).

Default: find job listings (search). If action is omitted, the request is treated as search. For closer matching on recent roles, pass resume_text and/or user_profile with search (still action=search); do not use any other tool name for this. Use refine when there are prior Hera job results or explicit user feedback. Use detail only with a specific job_id. Put search fields in search_jobs or parameters; refine in refine_recommendations; detail in get_job_detail.

Career transition / planning — same as career_transition_advice. Pass fields in career_transition_advice or career or top-level.
