revert: drop the iteration-5 bullet that #754 merged by accident#755
Merged
Conversation
#754 was branched while HEAD still sat on the iteration-5 commit, so the squash carried in a change I had measured as null and said I would not merge. This removes it. The task-tool skip conditions that #754 was actually for are untouched. The bullet ("Before running something you just wrote, confirm the specific assumptions it depends on...") rested on a purpose-level classification showing Claude Code inspecting more than clawcodex (2.43 vs 1.57-1.71 steps per trial). That result was a CLASSIFIER ARTIFACT: the regex anchored the verb at the start of the command, so clawcodex's `cd /app && grep ...` inspection calls fell into an "other" bucket instead. Stripping `cd`/`&&` prefixes before classifying reverses it: clawcodex Claude Code delta explore:inspect 4.93 3.95 +0.98 <- clawcodex inspects MORE meta 0.64 0.00 +0.64 author:inline 2.93 2.52 +0.40 run:exec 1.86 1.57 +0.29 So the premise was false, which explains the null measurement (4 of 5 tasks worse, mean 9.9 -> 10.2). Anchor a command classifier on the first real verb, not the first token. What survives from that analysis is the `meta` row: memory writes plus task-tool calls cost clawcodex 0.64 steps per trial where Claude Code spends ZERO across 21 trials -- 26% of the remaining gap. #754's skip-condition restoration addresses the task-tool half and stands on the dropped-qualifier argument, independent of the misclassified rows.

Memory writes plus task-tool calls cost clawcodex 0.64 steps/trial where Claude Code spends zero across 21 trials — 26% of the remaining gap. #754's skip-condition restoration addresses the task-tool half and rests on the dropped-qualifier argument, independent of the misclassified rows.Tests: 28 passing in the affected file; the #753 and #754 changes verified intact in the assembled prompt.
