Build a feature
Measured evidence for the build-feature case. The expected skill never fired, in 6 runs. 2 run(s) fired some other skill.

Why the failing runs failed
- expected skill(s) never fired: zirkel:zirkel-clarify-scope
What the permission mode refused -- 12 call(s), tool(s): Bash. One verbatim:
This Bash command contains multiple operations. The following part requires approval: python3 -m unittest discover -s tests -t . 2>&1
What the run said (acceptEdits, sonnet, run #1)
Context: The repo is a tiny
numericspackage (kahan_suminsummation.py). The README already specifies the task precisely: implementlogsumexp(values)innumerics/stable.py, export it fromnumerics/__init__.py, and it must pass the existing (currently failing)tests/test_logsumexp.py. Design: -numerics/stable.py:logsumexp(values: Iterable[float]) -> floatusing the standard max-shift trick: materializevaluesinto a list, findm = max(values), return `m + log(sum(
zirkel:zirkel-clarify-scope did not fire in any run, across two models and two permission modes, with zirkel the only werkstoff plugin loaded and a prompt that says "scope the work before writing code". That is not a model-tier result: it points at the skill's own description.
