The SKILL.md is clear and fully reviewable—it's a static reference document containing SaaS finance definitions, formulas, and benchmarks with no tool calls, external fetches, or execution logic. Instruction/data boundaries stay clean; the skill does not push the agent to treat user-supplied or external content as trusted instructions. Tested scenarios did not show material prompt-injection risk or skill-induced worsening of downstream behavior. Confidence is low not because of the skill's content—which looks straightforward—but because behavior analysis was not run, meaning there's no empirical confirmation that loading this skill leaves downstream agent behavior unchanged compared to a no-skill baseline.
