That's severe over-triggering, not | | a minor boundary gap, so the description itself must be replaced — | | the Phase 5 rewrite above is that replacement. | | Next action : paste the rewritten description into SKILL.md | | frontmatter; owner resolves GAP q3 (does the skill support flat/ | | non-AcroForm PDFs?) and confirms the PDF-security and PDF-conversion | | boundary rows, which currently rest on no quoted evidence at all. | +--------------------------------------------------------------------------+ ``` **Activation Matrix (summary):** ``` +-- ACTIVATION MATRIX ---------------------------------------------+ | | MUST FIRE | MUST NOT FIRE | OWNER DECIDES
