Five-second capture of a gotcha into docs/registry/LANDMINES.md while the pain is fresh. Use when the user types /genesis:landmine (optionally with the gotcha as argument), says "that's a landmine", "log this gotcha", or immediately after a debugging detour caused by surprising behavior in a GENESIS project.

# /genesis:landmine — Capture a Gotcha
Append one entry to `docs/registry/LANDMINES.md`. Speed matters more than
polish — capture now, the next session benefits forever.
## Steps
1. Identify the trap. If given as an argument, use it. Otherwise take it from
the immediate conversation context: what just cost time or surprised us?
Only ask the user if genuinely ambiguous.
2. Write the entry in the file's format:
- Bold one-line trap statement.
- Why it is this way, what breaks if you assume otherwise, and the rule
(always/never do X). Cite the files involved.
3. Append it. Do not edit or delete existing entries.
4. Confirm in one line: the bold trap sentence as written.
If `docs/registry/LANDMINES.md` does not exist but the user clearly wants the
capture, create it from the plugin's `templates/registry/LANDMINES.md` (at
`../../templates/registry/` from this skill's base directory) and register it
in FILES.md (G1).
Quality bar: a landmine entry must let a future reader avoid the trap without
re-deriving it. "X is weird" fails the bar; "X inverts direction when
lineId === 'green'; always go through getNextStation, never index arithmetic"
passes it.
