/**
|
|
* gemini-eval.mjs — Gemini-powered Job Offer Evaluator for career-ops
|
|
*
|
|
* A free-tier alternative to the Claude-based pipeline.
|
|
* Reads evaluation logic from modes/oferta.md + modes/_shared.md,
|
|
* reads the user's resume from cv.md, and evaluates a Job Description
|
|
* passed as a command-line argument.
|
|
*
|
|
* Usage:
|
|
* node gemini-eval.mjs "Paste full JD text here"
|
|
* node gemini-eval.mjs --file ./jds/my-job.txt
|
|
*
|
|
* Requires:
|
|
* GEMINI_API_KEY in .env (or environment variable)
|
|
*
|
|
* Free-tier model: gemini-2.5-flash (generous quota, no billing required)
|
|
*
|
|
* Model deprecation reference (per Google AI for Developers, May 2026):
|
|
* - gemini-2.0-flash deprecated 2026-03-31 (do not use)
|
|
* - gemini-2.0-flash-lite deprecated 2026-03-31
|
|
* - gemini-2.5-flash deprecated 2026-06-17 (current default)
|
|
* - gemini-2.5-flash-lite deprecated 2026-07-22
|
|
* Stable Gemini models follow a 12-month lifecycle from their release date.
|
|
* Source: https://ai.google.dev/gemini-api/docs/models
|
|
*
|
|
* When the current default approaches its deprecation date, bump
|
|
* `modelName` below and the `--model` examples accordingly.

IMPORTANT OPERATING RULES FOR THIS CLI SESSION
|
|
═══════════════════════════════════════════════════════
|
|
1. You do NOT have access to WebSearch, Playwright, or file writing tools.
|
|
- For Block D (Comp research): provide salary estimates based on your training data, clearly noted as estimates.
|
|
- For Block G (Legitimacy): analyze the JD text only; skip URL/page freshness checks.
|
|
- Post-evaluation file saving is handled by the script, not by you.
|
|
2. Generate Blocks A through G in full, in English, unless the JD is in another language.
|
|
3. At the very end, output a machine-readable summary block in this exact format:
|
|
|
|
---SCORE_SUMMARY---
|
|
COMPANY: <company name or "Unknown">
|
|
ROLE: <role title>
|
|
SCORE: <global score as decimal, e.g. 3.8>
|
|
ARCHETYPE: <detected archetype>
|
|
LEGITIMACY: <High Confidence | Proceed with Caution | Suspicious>
|
|
---END_SUMMARY---
