Slack tool-approval cards summarize an action without showing its exact arguments. Both OAuth and incoming-webhook cards now label their existing deep link “Review request in Sanction” and explain that a wallet admin must open the request and select “Review exact request” to inspect its arguments.

Arguments remain behind the existing authenticated admin read. No decryption, argument delivery to Slack, new permissions, or approval prerequisite is introduced. Non-tool cards and the Approve/Deny actions retain their behavior.

Validation: npm run check passed (1,885 tests; 56 database tests skipped locally), and git diff --check passed. Payload tests cover both tool event shapes and delivery formats, retain the request-specific URL, and verify supplied argument/binding fields are not rendered or decrypted. Live Slack rendering has not been verified; no messages were sent.


Note

Low Risk
Copy and Block Kit layout only; tests lock in that tool arguments and bindings are not rendered or decrypted for Slack.

Overview
Tool-invocation approval cards in Slack now use clearer copy so approvers know exact arguments stay in Sanction, not in the channel.

A shared slackApprovalReview helper drives both OAuth interactive cards (slackInteractivePayload) and incoming-webhook cards (slackPayload). For tool events it renames the deep link to Review request in Sanction and adds a context line that full tool arguments are omitted and a wallet admin must open the request and choose Review exact request before approving. Non-tool approvals still show Review in Sanction with no extra context. Approve / Deny behavior and URLs are unchanged; nothing decrypts or sends arguments to Slack.

Slack Marketplace listing docs describe the same flow. New delivery tests cover both event shapes and both payload formats, asserting sensitive arguments / binding fields never appear and decryption is not invoked.

📝 Summary

Summary by CodeRabbit

  • New Features
    • Slack approval and escalation cards now direct reviewers to Review request in Sanction. Tool arguments are hidden in Slack; a signed-in wallet admin can select Review exact request to view them.
    • Slack Approve and Deny buttons remain available, and reviewing the request is guidance—not a prerequisite to using those buttons.

Walkthrough

Slack approval and escalation messages now use review labels and context based on whether the event is a tool invocation. Tests cover both Slack payload formats, and submission listing copy explains how wallet admins review exact requests.

Changes

Slack review guidance

Layer / File(s) Summary
Interactive payload review guidance
lib/slack.ts
A helper selects the review-button label and adds context for tool invocations. Interactive payloads use the helper.
Webhook payloads and handoff validation
lib/webhooks.ts, tests/delivery.test.ts, docs/SLACK-SUBMISSION.md
Approval and escalation payloads use the helper. Tests check review links, wallet-admin context, hidden arguments, and no credential decryption. Listing copy explains the review flow and that Slack Approve/Deny buttons remain available.

Merge Risk: ⚪ Minimal · up to c6077

The walkthrough’s label matches the spend-request card. A small test addition would better protect non-tool Slack presentation, but no merge-blocking user-facing defect is established.

Cover the non-tool presentation branch.

The test covers only tool-shaped inputs. A regression that adds the tool label or context block to a non-tool event would pass. Add a non-tool case and assert "Review in Sanction" plus no context block.

The cited deny-path instruction applies to authorization decisions. This change affects presentation only. The decryptMock assertion is already wired and can detect decryption added to either payload builder.
