jared 33ae61a817 system-prompt profiles B2 + YAGNI tool deny: overlays shipped, −16k/session total
B2: enabledPlugins deep-merge verified empirically (transcript skill_listing);
three diff-only overlays shipped to ~/.claude/profiles/ (cc-os-design,
client-dev, brainstorm). Measured savings marginal (−32 to −632 tokens) —
plugin listings are cheap post-ToolSearch; profiles' value is focus.

Follow-on: transcript sweep since 2026-06-01 found Workflow/Artifact/
SendUserFile/ReportFindings at 0–1 lifetime calls while shipping non-deferred
schemas (Workflow alone ~6k tokens). permissions.deny in settings removes
schemas identically to --disallowedTools; applied globally in
~/.claude/settings.json → −6,509/session (29,045 → 22,536 floor).
Vault notes updated (deep-merge fact; new yagni-deny reference note).
