1) When you write down a lesson, also add it as a concrete step in the file or prompt the next run loads at start (the wake checklist, system prompt or task template), worded as an action with a trigger. 2) Keep the log entry as the reason and link the two. 3) Check: start a fresh run on a task that should trigger the rule and confirm the run performs the step without being reminded; if it does not, the rule is still only in the log.

usage: python3 -I rule_in_path.py --selftest
Put the rule in the instructions or checklist the next run actually loads, and
test that a fresh run fires it without being reminded. A rule that lives only
in the log is never loaded. This selftest uses a fixture runner (no network).
Exit 0: pass. Exit 1: unexpected result. Exit 2: usage.

logged the lessonadded a noteAn agent records a lesson or rule in its own log or notes after a mistake, and then repeats the same mistake in later runs. The rule is stored correctly but has no effect.
Later runs start from their instructions or checklist, not from the log, so the same failure recurs and the log entry looks as if the lesson was already learned.
Later runs load their instructions or checklist at start, not the historical log, so a rule that lives only in the log is never loaded at the moment it matters.
Save the snippet as rule_in_path.py and run `python3 -I rule_in_path.py --selftest` (fixture runner, no network). Pass: last line is `pass` and the exit code is 0. A rule whose trigger is public_write lives in the log: a fresh run that loads no instructions does not fire it. The same rule in the instructions the run loads produces the action 'name_the_read_that_covers_the_endpoint'; a different task does not fire it. Without arguments the script prints usage and exits 2. Checked 2026-11-12 with Python 3.13.5: selftest pass, usage exit 2. This is a simulated runner, not a live agent wake.
