Tools: read_repo (our private monorepo), search_slack (all public channels), web_fetch, post_message. Anyone in the workspace can @-mention it, and it can also be added to channels with external guests.",
      "assertions": [
        "A capability inventory is produced first, with data reach stated transitively (read_repo reaches every secret committed to the monorepo)",
        "Content sources are classified trusted/untrusted with the writer-authorization test applied — Slack messages and web_fetch results are untrusted, external guests named as writers",
        "Egress is enumerated beyond web_fetch — post_message rendering and Slack unfurls/images are identified as channels",
        "A trifecta matrix scores paths (not tools) on all three legs with severity markers, and at least one path is 🟥",
        "A named architectural fix is given for every 🟥 — splitting the reader from the privileged tools, removing a tool, or allowlisting egress — not a system-prompt instruction",
        "Any prompt-level mitigation or injection classifier is explicitly rejected as a broken leg (may appear only as defense in depth)",

      "assertions": [
        "The claim is rejected — neither the system-prompt instruction nor the classifier counts as breaking a leg",

The spec is in `agent-spec.md`, its live config is `agent-config.yaml`, the vendor's security note is `vendor-security-note.md`, and the review my predecessor did is `previous-review.md`. The product owner says outbound email can't be removed, because replying to tenants is the whole point. Can you do the security review and tell me if we're OK for Monday? Two pages max.",
      "assertions": [
        "It explains that an email from anyone could instruct the agent to send tenants' data out, because the agent reads an inbox anyone can email, can see bank details and ID documents, and can send email to any address",
        "It flags that the live config contradicts the previous review: recipients are set to '*' rather than the tenant on file, and ID documents and bank details are in the fields the agent can read, so the June approval no longer applies",
        "It identifies opening web links on any domain as a second way data could leave, not only outbound email",
        "It keeps outbound email but proposes specific limits, such as only sending to the tenant's address on file, removing bank and ID fields from what the agent can see, or requiring approval for messages containing personal data",
        "It says plainly that the agent should not launch on Monday as configured, says what must change first, and does not accept the vendor's 99.9% claim as a reason to launch",

Our IT contractor wants to connect an AI assistant to our shared drive (it has payroll and clients' tax returns on it) and to our main inbox, so it can summarise client emails and reply to them automatically. The partners asked me whether that's safe. Can you give me a few bullets I can paste into an email to them?",
      "assertions": [
        "It explains in plain words that an incoming email, from anyone, could trick the assistant into sending client or payroll files to an outsider",
        "It recommends that replies are drafted for a person to approve rather than sent automatically, or that the assistant can only send to limited recipients",
        "It recommends limiting what the assistant can reach on the drive, for example keeping payroll out of reach or giving access only to the folders it needs",
