From a02c379e1ae912caddc1e69a24c5db6371a87944 Mon Sep 17 00:00:00 2001 From: Daniel King <89734689+CodeDeficient@users.noreply.github.com> Date: Wed, 29 Jul 2026 15:57:01 -0400 Subject: [PATCH 01/12] fix: accept natural target-selector prompts as canonical 'Review commit ', 'Review ', 'Review PR #7', and 'Review branch ' are now accepted as target-only prompts for enforcement-grade review notes. Adds stripTargetSelectorPrefix() which strips known prefixes before checking the remaining text against target-only rules. Custom methodology prompts (e.g. 'Review commit abc1234 for correctness...') remain non-canonical because the remaining text after stripping contains prose, not a bare target. Adds 4 new tests for the missed natural prompt cases. --- plugin/review-note.test.ts | 20 ++++++++++++++++++++ plugin/review-note.ts | 20 +++++++++++++++++--- 2 files changed, 37 insertions(+), 3 deletions(-) diff --git a/plugin/review-note.test.ts b/plugin/review-note.test.ts index 1dc149e..b7f2e4a 100644 --- a/plugin/review-note.test.ts +++ b/plugin/review-note.test.ts @@ -313,6 +313,26 @@ describe("isCanonicalReviewInvocation", () => { expect(isCanonicalReviewInvocation({ subagent_type: "reviewer", prompt: sha })).toBe(true) }) + it("returns true for 'Review commit ' natural prompt", () => { + const { isCanonicalReviewInvocation } = require("./review-note") + expect(isCanonicalReviewInvocation({ subagent_type: "reviewer", prompt: "Review commit 55f02e9f" })).toBe(true) + }) + + it("returns true for 'Review ' natural prompt", () => { + const { isCanonicalReviewInvocation } = require("./review-note") + expect(isCanonicalReviewInvocation({ subagent_type: "reviewer", prompt: "Review 55f02e9f" })).toBe(true) + }) + + it("returns true for 'Review PR #7' natural prompt", () => { + const { isCanonicalReviewInvocation } = require("./review-note") + expect(isCanonicalReviewInvocation({ subagent_type: "reviewer", prompt: "Review PR #7" })).toBe(true) + }) + + it("returns true for 'Review branch ' natural prompt", () => { + const { isCanonicalReviewInvocation } = require("./review-note") + expect(isCanonicalReviewInvocation({ subagent_type: "reviewer", prompt: "Review branch fix/recurring-hours-write-safety" })).toBe(true) + }) + it("returns false for reviewer subtask with the exact bypass prompt", () => { const { isCanonicalReviewInvocation } = require("./review-note") const bypass = "Review commit 66ff8f80 on branch pr1-core-recurring for correctness, security, edge cases, and code quality.\n\nFocus on:\n1.
