Thanks for this, and for filling the eval gap for extract-code and rewrite. Two rules were lost in the condensing, one new fixture is ambiguous, and the branch needs a rebase before CI can run. Details below and inline.
Rebase needed — conflicts are in generated files only
The branch is 6 commits behind main and conflicts in docs/mode-economics.md and tools/skill-evals/README.md. Both are generated counts that moved on main (#1372, #1373). Please rebase, then regenerate them rather than hand-merging:
uv run --project tools/skill-token-count skill-token-count --write
python3 tools/dev/check-doc-sync.py --fixCI has not run on this PR yet because of the conflict.
Two rules were lost in the condensing
A wording pass must keep what the skill decides. The umbrella asks for exactly that ("headings, golden-rule headlines, code blocks and the pre-flight block kept byte-identical"), and this skill's own Hard rules say "Structure changes, behaviour does not". Two sentences carried rules and did not survive:
- Step 4: "the budgets from What counts as small enough must have moved the right way" became "measure both budgets again". Measuring is no longer tied to an outcome, so a pass that grows the skill is no longer caught.
- Hard rules: "A pass that needs it relaxed is not an optimization" is gone. "Require a green validator" can be satisfied by loosening the validator, which is exactly what the old sentence forbade.
Suggested wording is inline. The rest of the condensing keeps the rules. It mostly drops the why sentences, which is a fair trade for this pass.
Evals: run them, and note what they cannot see
The test plan says the seven cases were loaded and reviewed, not run. #1350 step 4 and AGENTS.md both ask for the suite to run before and after:
tools/skill-evals/magpie-run-evals.sh tools/skill-evals/evals/optimize-skillPlease include the before/after result in the description. Note also that the suite only extracts ## Step 1 — Diagnose, which this PR leaves unchanged. So a green run proves the new fixtures, but says nothing about the rewritten Steps 2–5 and Hard rules. Those rest on review, which is why the two lost rules above matter.
Smaller observations
case-7-verbose-prose/report.md: the fixture says the largest section is "substantially longer than the other orchestration sections". Smell 1 in Step 1 triggers split on "one section dominating", so a model can reasonably return["split", "rewrite"], and the case becomes flaky. Case 2 says "within range, no dominating section". Use the same wording here.- Scope: #1350 asks for the utilities family, starting with the three skills over the always-on budget (
report-framework-issue,skill-reconciler,list-skills).optimize-skillwas already within both budgets. Please changeCloses #1350toPart of #1350so the issue stays open for the rest.

This dropped the outcome: on main Step 4 says the budgets "must have moved the right way". As written, a pass that grows the skill still passes Step 4.

The old rule also said "A pass that needs it relaxed is not an optimization." Without it, "require a green validator" can be met by loosening the validator. Please keep that clause.

"Substantially longer than the other orchestration sections" reads as smell 1's "one section dominating", which triggers split, so ["split", "rewrite"] is a defensible answer and the case will be flaky. Case 2 phrases it as "within range, no dominating section"; the same here would leave rewrite as the only answer.

Thanks @anbv29. The text fixes in SKILL.md (Step 4 budget direction, Hard rules validator clause) and case-7-verbose-prose/report.md address the wording findings.
However, the PR is not ready to merge yet due to the following blocking items:
-
Git history / rebase (PR diff is bloated to 66 files):
- The branch has pulled in 6 unrelated commits from
main(#1382–#1387) into its own commit history rather than rebasing cleanly. As a result, the PR diff currently touches 66 files across the repo instead of being scoped tooptimize-skill. - Please rebase cleanly onto latest
upstream/main(git rebase upstream/main) so the diff contains only your changes, then regenerate the sync files if needed:uv run --project tools/skill-token-count skill-token-count --write python3 tools/dev/check-doc-sync.py --fix

Notes for reviewers
The rewrite preserves the existing workflow, approval boundaries, validator gates, and seven-pass diagnosis contract. The main change is reduced recurring context cost plus complete eval coverage.
