Description

Makes every source-control practice-feedback lane clearly identify AI-generated content. The disclosure is applied by the shared delivery formatter, including to inline review comments and proposals released after human approval—the two paths that previously bypassed it.

What recipients will see in each lane

The examples below use claude-sonnet-4 to show the optional model segment and an illustrative settings URL. In production, the link uses the deployment's configured webapp URL. If model metadata is unavailable, the model segment disappears cleanly.

Pull/merge-request summary

One footer describes the complete review, below the summary separator:

Practice review

Extract authorization into the service boundary
Both callers currently repeat the same check. Centralizing it would keep the policy consistent.

Keep the transaction around the state change
Moving the write outside the transaction can expose a partially updated result.


Practice review · claude-sonnet-4 · AI-generated and can be inaccurate. React with 👍 or 👎, or reply, to give feedback.
Why you're seeing this and how to stop it

Issue feedback

Issue feedback uses the same summary-style ending:

The acceptance criteria describe the happy path, but not what should happen when authorization expires during the operation. Adding that case would make the expected behavior testable.


Practice review · claude-sonnet-4 · AI-generated and can be inaccurate. React with 👍 or 👎, or reply, to give feedback.
Why you're seeing this and how to stop it

Inline review comment

The disclosure stays with each line-specific suggestion, even when the comment is viewed independently from the summary:

AuthorizationService.java, line 84

Consider moving this check into the service method so every caller follows the same authorization policy.

AI-generated · React with 👍 or 👎, or reply, to give feedback.

Inline notes retain the essential AI label and the useful per-finding interaction cue. They deliberately omit the repeated model name, accuracy sentence, and settings link; the containing top-level review owns that fuller context.

Admin-approved proposal

Human approval controls whether the proposal may be delivered; it does not erase how the proposal was produced. The approved body receives the same disclosure at delivery time:

The new endpoint performs the same permission check in two places. Extracting it into the application service would reduce the chance that future callers bypass it.

Practice review · claude-sonnet-4 · AI-generated and can be inaccurate. React with 👍 or 👎, or reply, to give feedback.
Why you're seeing this and how to stop it

Missing model metadata

All source-control lanes degrade to the same compact footer rather than showing an empty placeholder:

Practice review · AI-generated and can be inaccurate. React with 👍 or 👎, or reply, to give feedback.
Why you're seeing this and how to stop it

Slack reminder

Slack reminders retain their existing deterministic notification copy and receive no AI label. They point recipients to feedback delivered elsewhere; they are not themselves model-generated feedback. In other words, this PR does not turn a reminder such as “New practice feedback is available” into an “AI-generated” message.

Settings reached from every disclosure

The shared link lands directly on the practice-feedback section, which explains both why delivery occurs and what opting out changes:

Turn this off to stop new comments on issues, pull requests, and merge requests you author, and related Slack reminders. Reviews still run, and workspace admins can still see the resulting observations.

Delivery identity

The body-level disclosure is present regardless of provider identity. For GitHub, the integration guide now distinguishes synchronization from delivery: personal access tokens remain supported for synchronization, while active feedback delivery should use a GitHub App so comments also have a distinct App identity. This provides both signals where GitHub supports them without pretending that a PAT posts as a bot.

No migration or new configuration is introduced.

Fixes #1360

How to test

  • Trigger practice feedback that produces a pull/merge-request summary, inline review comment, issue comment, and an admin-approved proposal.
  • Confirm each top-level summary, issue comment, and approved proposal says it is AI-generated and includes the link “Why you're seeing this and how to stop it.”
  • Confirm each attached inline note shows only “AI-generated · React with 👍 or 👎, or reply, to give feedback.”
  • Verify the optional model name is shown on top-level feedback when present and omitted cleanly when absent.
  • Follow the link and confirm the practice-feedback settings explain delivery and provide the comments/Slack-reminders control.
  • In GitHub App mode, confirm feedback is authored by the App identity.
  • Confirm deterministic Slack reminders retain their existing copy and do not receive a misleading AI label.
  • Automated coverage: pnpm run check, pnpm run test:webapp, and the full server unit suite with the quick profile disabled.

Checklist

  • My changeset summary reads as an operator/user-facing note (it becomes the changelog entry) — see .changeset/README.md
  • If the operator must act on this change (new required env var, manual migration step), the changeset summary says how (**Operators:** …) and MIGRATION.md is updated

📝 Walkthrough

Walkthrough

Practice-review comments now include standardized AI-generated disclosure text and delivery-specific prompts. Approved feedback and inline feedback use the shared formatter. Tests, GitHub integration guidance, contributor language, and settings copy reflect the updated behavior.

Changes

AI feedback disclosure

Layer / File(s) Summary
Standardize disclosure formatting
server/src/main/java/.../PracticeFeedbackCommentFormatter.java, server/src/test/java/.../PracticeFeedbackCommentFormatterTest.java
Adds inline feedback prompt formatting and updates the metadata footer to invite replies. Tests cover both formats.
Apply disclosure to delivery paths
server/src/main/java/.../ApprovedFeedbackDeliveryListener.java, server/src/main/java/.../DiffNotePoster.java, server/src/test/java/.../ApprovedFeedbackDeliveryListenerTest.java, server/src/test/java/.../DiffNotePosterTest.java
Approved feedback now uses appendDisclosure. Inline feedback now uses appendInlineFeedbackPrompt. Tests verify formatted content and reconciliation behavior.
Align delivery guidance and settings copy
docs/admin/github-integration.mdx, docs/contributor/practice-feedback-language.md, webapp/src/components/settings/PracticeFeedbackSection.tsx, .changeset/clear-ai-feedback-disclosure.md
Documentation and settings copy describe AI-generated feedback, delivery controls, authentication guidance, and naming rules.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 7ebea

This PR adds AI disclosures across feedback delivery paths and is mergeable with explicit owner awareness because boundary-size feedback may still exceed the configured comment length limit, potentially affecting how that feedback is delivered. The remaining test-name cleanup is localized and non-blocking.

Explanation

The changes satisfy the source-control requirements in issue #1360 by adding AI-generated disclosures, delivery explanations, links, inline prompts, and GitHub App identity guidance. However, issue #1360 also requires recognizably AI-generated feedback in Slack, while the pull request explicitly leaves Slack reminders unchanged and without an AI label.

Resolution

Add the required AI authorship label and supporting disclosure to applicable Slack feedback delivery paths, or update the linked issue and scope to exclude Slack explicitly. Verify bot identity requirements for each supported channel before merging.

Full details: Out of Scope Changes check

Explanation

The documentation, settings copy, formatter changes, delivery handlers, and tests all support AI-authorship disclosure and feedback-delivery behavior. No unrelated code or documentation changes are evident.

Keep the final comment within the delivery length limit.

PullRequestCommentPoster.sanitize() can return a body at MAX_BODY_LENGTH. This method then appends the disclosure footer. A maximum-length body can exceed the provider limit and the provider can reject the feedback.

Reserve the footer budget before sanitizing, or enforce the limit after formatting.
