From e4f94fa5fb3b18499216805eb94e7bf8241f8ed9 Mon Sep 17 00:00:00 2001 From: OfficialDelta <51007646+OfficialDelta@users.noreply.github.com> Date: Tue, 7 Apr 2026 23:23:55 -0400 Subject: [PATCH] feat(context): implement R005 decision scope cascade and derive scope from slice metadata MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fix 1 - Fallback cascade: - inlineDecisionsFromDb() now cascades: milestone+scope → milestone only → null - When scoped query returns empty AND scope was provided, retries without scope - Falls back to milestone-level decisions when no scope-specific ones exist Fix 2 - Derive scope from slice metadata: - Added deriveSliceScope(title, description?) helper function - Extracts first meaningful noun (filters stopwords and generic words) - Examples: 'Auth Middleware & Protected Route' → 'auth' 'Integration Testing' → undefined (too generic) - Wired into buildPlanSlicePrompt and buildResearchSlicePrompt Added comprehensive test suite (13 tests) covering: - Keyword extraction from slice titles - Generic title detection - Cascade fallback behavior - Integration between scope derivation and cascade --- src/resources/extensions/gsd/auto-prompts.ts | 78 ++++- .../gsd/tests/decision-scope-cascade.test.ts | 296 ++++++++++++++++++ 2 files changed, 369 insertions(+), 5 deletions(-) create mode 100644 src/resources/extensions/gsd/tests/decision-scope-cascade.test.ts diff --git a/src/resources/extensions/gsd/auto-prompts.ts b/src/resources/extensions/gsd/auto-prompts.ts index a6fbf86ea..a3d86cffd 100644 --- a/src/resources/extensions/gsd/auto-prompts.ts +++ b/src/resources/extensions/gsd/auto-prompts.ts @@ -262,7 +262,11 @@ export async function inlineGsdRootFile( /** * Inline decisions with optional milestone scoping from the DB. * Falls back to filesystem via inlineGsdRootFile only when DB is unavailable. - * When DB is available but cascade returns empty, returns null (empty is intentional per D020). + * + * Cascade logic (R005): + * 1.
