Conversation
TauCetiProject/TauCetiReview#224 sends the shared protocol and the pull request as a separately cached prompt block, so the rubrics after the first in a round read the PR from the prompt cache instead of writing it again. Re-pin every TauCetiReview reference together: tauceti.toml, the auto-merge and merge-sweep callers, and the merge-policy checkout. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…che hit (#263) TauCetiProject/TauCetiReview#227 gives all the Claude attempts of a review one HOME, so Claude Code's system prompt no longer changes between rubrics and the later rubrics of a round read the PR from the prompt cache. Re-pin every TauCetiReview reference together, as in #262. Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

Reviews of LMLExplore PRs run TauCetiReview at the commit pinned in
tauceti.toml, still32ce206. TauCetiProject/TauCetiReview#224, merged asec743f1, sends the shared protocol and the pull request first, as a separately cached block. The rubrics after the first in a round then read the PR from the prompt cache instead of each writing its own copy.In the reviews one worker ran on LMLExplore from 30 October to 9 November (5,168 rubric runs on 228 PRs), cache writes were $1,331 of the $1,579 total, at API prices. The first request of every rubric read only Claude Code's 3,223-token system prompt from the cache.
Changes: every TauCetiReview pin,
32ce206→ec743f1, all at once as.github/actions/checkout-merge-policy/action.ymlasks:tauceti.toml:[tools.review] ref, which the workers use to run reviews;.github/workflows/auto-merge.ymlandmerge-sweep.yml: theuses:lines andreview_ref;.github/actions/checkout-merge-policy/action.yml: the merge-policy checkout.TauCetiTools' project template fills these values from
tauceti.toml, so a later re-render keeps them. The comments refer toscripts/test_workflow_pins.pyto check that the pins agree, but that script isn't in the repository; I checked by hand that all six agree.Between the two commits (40 commits):
merge-only.ymlandmerge-sweep.ymlkeep the same inputs and secrets. Their only change isruns-on, and only for TauCetiProject/TauCeti.rubrics/README.mddiffers, which changes the rubrics fingerprint. Approvals stay tied to the head commit, so open PRs are not re-reviewed. An approval is not carried over to a rebased head with an unchanged patch, so those rubrics run once more.The new prompt layout needs Claude Code 2.1.242 or later on the machine running the reviews. With an older CLI, reviews keep the old layout and work as before.
Like #109, this PR changes a pin and
.github/, so it may need an admin merge. After the merge, restart running workers so that they pick up the new pin.Roadmap: none
