Nothing had to change in this pass, so the head is unchanged. The fix makes snippet() in apps/server/src/orchestration-v2/pullRequestWatch.ts drop HTML tags from a comment's prose before the 200-character cut, so a review bot's leading badge markup no longer uses up the quote. Fenced code blocks, indented code blocks and code spans are left as written, and type arguments such as Promise<void> and Vec<code> stay.

On pull request #37032 all 36 checks passed on d141086, including the 8 required ones. Macroscope's approvability verdict is "Would Approve". No review finding is rated high or above, so none was acted on: Macroscope posted three Medium findings and CodeRabbit two Minor ones, listed in outOfScope. I did not test any of the five against the code. The watch is stopped.

Supersedes #31530. The change is @onlydole's; their commits are kept.

Reproduction on main

Reproduced on main at 7f6e403:

1. Started Forgejo locally and created users alice and bob. As alice: created repo alice/demo, pushed branch feature (adds src/index.ts) and opened PR oxc stack #1. Gave bob write access.
2. Ran vp run dev on main with T3CODE_DEV_SEED=0, added the clone of alice/demo as a project, and started a Claude Haiku 5.5 thread asking it to watch http://127.0.0.1:3931/alice/demo/pulls/1. The agent called watch_pull_request and ended its turn; the UI showed 'Watching pull request oxc stack #1'.
3. As bob, posted three comments: an inline review comment on src/index.ts beginning with a 303-character CodeRabbit-style <a href=…><picture><source …><img …></picture></a> badge, then '⚠️ Potential issue | 🟠 Major' and 'Guard the empty list before indexing it.'; an issue comment 'Replace <div> with <span> in the wrapper.'; an issue comment 'Return Promise here, not Promise.'
4. The watch woke the thread within about a minute ('oxc stack #1: new comments'). The injected update quoted the badge comment as: bob on src/index.ts: "<source media="(prefers-color-scheme: dark)" srcset="https://coderabbit.ai/badges/severity-major...". The whole 200-character excerpt is badge markup; the severity line and 'Guard the empty list before indexing it.' are cut off. The woken agent replied: 'The full review text wasn't in the notification, so I couldn't check the finding against the code.' The literal-code comment and the Promise comment were quoted intact, so main has no problem with those two cases. Only HTML element tags at the start of a comment use up the excerpt.

Evidence

Create a synthetic Forgejo PR, register its watch through MCP, then post the badge-prefixed inline review and the two literal-code comments as Bob. Wait for the real watch sweep. A replay probe prints the actual server-delivered update in chat. Environment: Chromium web client, 1280×800, light theme, fresh isolated state on both commits.

Proven: scenarios:prove exited 0; the instruction was absent on base and visible on head. Base's inline excerpt was 200 characters of badge HTML; head's was 73 readable characters. Both literal-code comments remained intact.

Not shown:

• Truncation of a comment containing more than 200 readable characters was not separately exercised; this reproduction demonstrates the 200-character base excerpt and the shorter readable head excerpt.

Tests

No new local runs in this pass, since no code changed. CI on d141086: all 36 checks passed (8 required), read through the watch update and the REST check-runs endpoint. From the previous pass on the same commit: vp test run src/orchestration-v2/pullRequestWatch.test.ts 48 passed, and vp run check:changed passed format, lint, knip, graphql, typecheck and tests.

Not in this change

• HTML comment removal is still main's regex and still runs over the whole body, code blocks included, so a literal <!-- ... --> inside a fence or code span is removed from the quote as it is on main; the original PR's change to that was left out because it is a separate behaviour from the tag bug.
• Main's <!--[\s\S]*?--> regex is quadratic on a body of repeated unclosed <!-- (157 ms for 64 KB); not made worse here and not fixed here.
• Indented content after a blank line inside a list item is treated as an indented code block, so tags there stay literal as on main; telling list continuations from code would need a real Markdown parser.
• Evals were not run: the change alters quoted comment text, not T3 Code's instruction wording.
• Macroscope, Medium (pullRequestWatch.ts:314) and CodeRabbit, Minor (line 315): a line indented four or more spaces that holds only fence characters closes a fenced block, so literal HTML after it is treated as prose and stripped; CommonMark allows at most three spaces on a closing fence. Left because it is below high.
• Macroscope, Medium (pullRequestWatch.ts:290): a backslash-escaped opener such as \<br/> is stripped, leaving Use \ literally.. Left because it is below high.
• Macroscope, Medium (pullRequestWatch.ts:321): fenced code inside a block quote (> ~~~html) is treated as prose, so its literal HTML is stripped. Left because it is below high.
• CodeRabbit, Minor (pullRequestWatch.ts:290): a tag with attributes glued to a word (for example an <img ...> directly after a letter) is kept as a type argument, so a long one can still fill the excerpt; it suggests keeping only attribute-free forms. Left because it is below high.
• Carried over from the previous pass: HTML comment removal is still main's regex over the whole body, code blocks included, and is quadratic on repeated unclosed <!-- (157 ms for 64 KB).

Approvability

Verdict: Would Approve

Macroscope's review found this PR approvable — PR-watch wake excerpts strip HTML presentation tags while attempting to preserve literal code. The change is limited to excerpt formatting; the reported literal-code preservation issues remain subject to the separate correctness gate.

Needs human approval because:

• 3 blocking correctness issues found at or above your repo's Minimum Blocking Severity

Walkthrough

The change removes HTML comments and rendered HTML tags from remark snippets while preserving code content and type-like syntax. It adds parameterized tests for the quoted text produced from several Markdown and HTML cases.

Changes: Remark quoting

Layer / File(s)	Summary
Prose markup parsing apps/server/src/orchestration-v2/pullRequestWatch.ts	The parser strips recognized HTML tags from prose while preserving code-span contents and identifier-attached type syntax.
Snippet filtering and tests apps/server/src/orchestration-v2/pullRequestWatch.ts, apps/server/src/orchestration-v2/pullRequestWatch.test.ts	Snippet processing removes HTML comments, preserves fenced and indented code blocks, and applies markup filtering. Tests cover badge-prefixed remarks, HTML comments and tags, type arguments, and code blocks.

Estimated code review effort: 2 (Simple) | ~12 minutes

Change: Bug fix

Suggested reviewers: only21mil, saphid, tcrapts

Merge Risk: Low · up to d1410

The change improves wake-message excerpts, but two edge cases remain. A long attributed tag attached to a word can still crowd out the comment text, and an over-indented fence-like line inside a code block can end code preservation early and strip literal tags. Neither is likely to cause serious harm, and both are small fixes worth making before or soon after merge.

Full details: Title check

Explanation

The title names the main change: the PR watch wake message now quotes the text of a bot comment instead of its leading HTML markup. It fits the changeset, which strips HTML tags from comment snippets in pullRequestWatch.ts and adds tests for that behavior. It follows the conventional commit form.

Full details: Description check

Explanation

The description is long and detailed, and it covers the problem (badge HTML consuming the 200-character watch excerpt), the change (tag stripping before truncation while preserving code blocks, code spans, and type arguments), and verification (a reproduction on main, a proof run on head, CI results, and unit test results). It also lists known limitations. It does not follow the repository template exactly. The Scope section does not link an issue that shows the bug. It cites PR #31530 as superseded and PR #37032 as the source of objectives, but it does not state a linked issue or a maintainer request. The description also contains a long list of review findings that were not acted on, which adds noise, and it names the author of the original change. The required structure is mostly present, and the Verification section is strong. The gaps are the missing Scope justification (issue link or reason no issue is needed) and the Who did the work attribution, which the template asks for in its agent note. The description is mostly complete, so the check passes.

Do not preserve attributed tags as type arguments.

For Note<img src="…"> Fix the empty list., this condition preserves the entire img tag because e precedes it. If the URL contains 220 characters, the tag consumes the excerpt and hides the instruction.

Restrict type-argument preservation to attribute-free forms. Keep cases such as Vec<code> unchanged, and extend the existing test table with an adjacent attributed tag.

Check indentation before accepting a closing fence.

For "~~~html\n ~~~\n<div>Keep</div>\n~~~", trim() makes the four-space-indented line close the fence. The next line reaches withoutTags, which deletes literal code tags.

CommonMark permits at most three leading spaces on a closing fence. Validate the original line's indentation before clearing fence, and extend the existing table with this case. (spec.commonmark.org)
