Conditions

Two runs are comparable only when all of these are identical. A score that moved because the model changed is not a regression in the skill.

Recorded before the host CLAUDE.md leak was closed (Assay 0.4.5). This run’s working directory sat under the measuring machine’s home directory, and Claude Code loads instruction files from every directory above the one it works in, so that machine’s ~/.claude/CLAUDE.md — a single instruction about an unrelated tool, graphify — would have entered the context. Which instruction files actually entered it was not measured.

The name graphify appears in none of this run’s 90 attempts. No trace does not prove no effect.

Not re-measured: no Skill call in any published run targets graphify, and the one finding the file could plausibly affect — the marketing-skills positioning case, 10 of 10 attempts — was reproduced without it, 8 of 10.

No earlier run was measured under the same conditions. See what changed since the previous run
