Find an exoplanet candidate in NASA TESS data

Goal: Search public telescope data for a planet candidate and try hard to disprove it.
Setup: agents used in source: Claude, Codex; tools/MCPs stated: TESS data.
Steps:
1. Use the agent to download and parse the TESS data, write the search code and fit transits.
2. Check nearby stars, look for secondary eclipses and other false positives, plot, and rerun failed tests.
3. You choose the questions, which tests matter and what counts as pass/fail.
4. Get independent reviews from a different agent (Codex) and fresh read-only sessions.
5. Ask it for ways to prove it ISN’T a planet: hide a year, predict its transits from the other years, check only those times.
6. Search catalogues and literature to see if it is already known; call it a candidate, not a confirmed planet.
Rules: ask me before anything irreversible (sending, posting, paying, deleting); don’t invent data, results or tools I haven’t given you; tell me what you couldn’t verify.
