guard

Stops the model from paying twice for the same result.

Mechanism

An identical Read or Bash call (same tool, same normalised input) within the last N turns of the same session is denied with a reason pointing at the earlier result:

guard: identical to toolu_… 2 turns ago — use rtok expand <archive_id> or change the input

Denials are lossless because the earlier result is archived; the model can always expand.

Config

[plugins.guard]
enabled = true
window_turns = 8

Tasks

See roadmap.md § guard. Checks in plan.md.

T2.6 deny duplicate Read/Bash within window_turns when an archive id exists.

Status

Manifest only.
