Claude session-start-profiler no longer requires CLAUDE_ENV_FILE to persist likely skills or greenfield state.
Those values now come from the hook input session ID and are written to session files,
while Claude env exports remain only for the other profiler vars.

formatOutput now emits a single skill-upgrade instruction block per target skill, adds the requested blank line and reason text, and marks hard upgrades as REQUIRED so agents get clearer follow-up actions.

Instead of injecting the full SKILL.md body as additionalContext, inject
"You must run the Skill(<name>) tool." — a more conventional way of
telling the agent to use the Skill tool for context loading.
Refine SKILL.md content across 29 skills based on live eval findings from 16
benchmark sessions. Add .claude/skills/vercel-plugin-eval/ for running real-world
plugin eval sessions with debug log monitoring. Update posttooluse-validate and
validate-rules tests to match refined skill content.
