From d6711716984a98721a283422e2625aba6443267c Mon Sep 17 00:00:00 2001 From: Tom Boucher Date: Mon, 6 Jul 2026 10:04:41 -0400 Subject: [PATCH 1/7] feat(#1575): complete agent-converter descriptor cutover for copilot/antigravity + surface path parity MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Teach applySurface to build agentCtx (pathPrefix + attribution) and pass it to kind.stage() for agents kind, mirroring createRuntimeArtifactInstallPlan (ADR-1235 §1). Surface-path agents now receive path-rewrite + attribution + converter + normalize, matching install output byte-for-byte. - Pass skills:'*' sentinel for agents staging when no surface state modifications exist, so ALL agents are staged (not just those referenced by _calls_agents_). - Declare converted agents kind in copilot and antigravity capability.json; add to _DESCRIPTOR_AGENTS_RUNTIMES in bin/install.js. - Handle copilot .agent.md filename rename in both _copyStaged (install path) and _syncGsdDir (surface path). - Ship golden-parity harness (ADR-1235 §0): tests/issue-1575-agent-descriptor- parity.test.cjs asserts applySurface output is byte-identical to installRuntimeArtifacts for all 7 descriptor-driven runtimes, plus stale- cleanup convergence and prune data-loss coverage. - Update ADR-1235 with cutover progress.
