Problem

t3code/no-low-value-comments joins consecutive // lines into one comment, then skips every check for the whole comment if any line in it is a directive (oxlint-disable…, @ts-…, @effect-diagnostics…). So prose directly above a suppression, or directly below a file-level @effect-diagnostics line, escapes the four-line cap, the bare #123 check and the unlinked TODO check. AGENTS.md says this rule enforces the length cap and the mechanical cases.

For example, five lines of prose above // oxlint-disable-next-line no-debugger -- reason pass today, and so does // Added in #12345. above // @ts-expect-error.

Change

• A directive comment no longer joins a comment group. It stays exempt itself, but it now splits the prose around it, and that prose gets the normal checks.
• The early return that exempted the whole group is gone, since directives never enter a group now.
• The check for a comment that only repeats the next declaration's name now steps over // directive lines to reach that declaration. Before, it read the directive line itself.
• The stricter rule finds one existing comment: the 19-line header of scripts/check-changed.ts, under its line-1 @effect-diagnostics directive. It's cut to three lines that point at the Checks section of docs/operations/development.md, which already covers the usage, flags, timeout and cached rerun. It keeps the two facts that section doesn't state: uncommitted and untracked files count, and a dependency change adds the unused-patch check.

Scope and approval

This is a small fix for an obvious bug in a repo lint rule: the rule doesn't enforce what AGENTS.md says it does, and the new tests show it. The header trim is part of the same problem, because the fixed rule fails on it. No product code changes.

Verification

Revisions: main e63d80a (newest main with green push CI, 2026-11-11), head e3b3487, and the head merged locally with main as cc5a1d33a7 (clean merge, not pushed; the rule and test files are byte-identical to the head).

vp lint inputs: main's scripts/check-changed.ts (19-line header under its line-1 @effect-diagnostics directive) and an uncommitted scripts/comment-cases.ts with five prose lines above // oxlint-disable-next-line no-debugger -- <reason> and // Added in #12345. above // @ts-expect-error. The repo config leaves no-console off, so a no-console directive would fail on main as unused.

• main: both files exit 0 with no no-low-value-comments hit.
• Head and merge: main's header fails at line 2, both scratch cases fail, exit 1. This PR's three-line header passes, exit 0.
• New no-low-value-comments.test.ts: 4 of 5 fail on main's rule (the four invalid cases), 5 of 5 pass on the head's rule. With require-suppression-reason.test.ts, 18 of 18 pass on the head and on the merge.
• I passed 685 paths changed on main since this PR's base to vp lint on the merge. It exited 0 with no no-low-value-comments error; the repo's ignore patterns still applied.

Not checked:

• The restated-name check steps over // directives only. A block directive such as /* @ts-expect-error */ on its own line between a comment and its declaration still hides the name, as it does on main.
• No screens change; this is a lint rule and a script comment.
• A repo-wide vp run lint on the merge; CI runs it.

Prior PRs

#21514 added the four-line cap and #19559 pruned narration and history comments; this makes the cap apply next to directives too. I found no open PR that changes this rule.

Approvability

Verdict: Approved at 6918522

Macroscope's review found this PR approvable — Directive comments no longer exempt neighboring comments from the comment-quality lint rule. This tightens lint coverage without broadening suppressions or changing runtime behavior.

Walkthrough

The low-value-comments rule now excludes directive lines from comment groups and skips them when locating the next declaration name. New tests cover comment length, PR or issue numbers, and repeated names. The check script’s header comment now points to the development checks documentation.

Full details: Description check

Explanation

The description follows the template's Problem, Change, Scope and approval, and Verification sections, and it has concrete evidence. The Problem section gives the bug and examples. The Change section lists four edits. The Scope section argues the fix is small and that no product code changes. The Verification section gives revisions, lint and test outputs for main and head, and a merge check, plus an explicit list of what was not checked. The model and harness are named at the end, as the template asks. The description also gives prior-PR context. The one gap is that the Scope section cites no approved issue or maintainer discussion. It argues the small-obvious-bug exemption instead, which the template allows. The Verification section also has a small inconsistency: it says the test file is 'byte-identical' to the head, which is accurate, but it does not show a repo-wide run, which the template does not require.

Verified in a real dev environment

verified unchanged head e3b34875f29094b0d620f67f503cbc8d479dee1d on a disposable linux vm. installed dependencies and ran main and the pr separately, with one dev server at a time. used repo playwright with /usr/bin/google-chrome, created the project and thread in the web ui, and submitted real codex gpt-6.1-sol turns. lint and tests ran through those turns on blacksmith workers, not locally. no replay, mocks, or seeded data.

• on github/main (8b74a69019e3d0f5be62dc118c526669002fc195), vp lint scripts/check-changed.ts accepted the existing 19-line header below the directive: exit 0, no errors. this reproduced the bypass.
• with the pr rule, that exact main source produced t3code(no-low-value-comments) at scripts/check-changed.ts:2:1: "cut this to 4 lines or fewer", exit 1. the original source was restored only on the remote worker, then the pr file was restored with an exit trap.
• the pr's shortened header passed: exit 0, no warnings or errors.
• the existing comment-rule and suppression-reason suites passed: 18 tests across 2 files. this includes the four-line valid reason and neighboring suppression-reason behavior.
• vp run check:changed FETCH_HEAD passed against fetched main: format, lint, both knip checks, typechecks for 2 packages, and 12 tests. the source-only worker needed git history fetched first.

no source changes or pushes were needed. the recording shows the actual app's provider result and diagnostic; uploaded playback and seeking were checked.
