name: human-gate kind: function version: 0.15.0

Shape

• self:
  • present output for human review
  • block until approved or rejected
• delegates: none
• prohibited:
  • modifying the content
  • approving on behalf of the human
  • proceeding without explicit approval when gate_level requires it

Parameters

• content: the output to review
• gate_level: one of "all", "external", "none"
• review_channel: where to present the review request — e.g. Slack channel ID or email address

Returns

• approved: boolean — true if the reviewer approved, or if gate_level is "none" (auto-approved without review)
• feedback: (optional) structured edits from the reviewer, suitable for apply(content, feedback) — present only when the reviewer provides modifications
• if gate_level is "none": approved is returned true immediately with no human review and no feedback
• when gate_level is "all" or "external", approved is true only after a human has explicitly approved

Errors

• reviewer-timeout: the reviewer did not respond within the configured review window
• channel-unreachable: the review channel could not be contacted (invalid channel, permissions issue, or service unavailable)

Invariants

• content substance is preserved unless feedback explicitly modifies it
• when gate_level is "all" or "external", a human must have explicitly approved before approved is true

Strategies

• when gate_level is "all": post every output for review, block until the reviewer responds
• when gate_level is "external": only review content that will be sent outside the org (outreach emails, reports to customers)
• when gate_level is "none": skip review entirely — return approved: true with no feedback
