Fold CodeBuddy's residual runtime-literal branches onto descriptor-driven hostBehaviors (the issue's "zero branches remain" premise was inaccurate — 2 lived): - Folded the `if (isCodebuddy)` commands/ report duplicate (byte-identical to the generic reportCommandsDir block above it) onto hostBehaviors.reportCommandsDir:true, matching cursor's #2089 precedent. - Deleted the dead `else if (isCodebuddy)` agent-conversion arm (codebuddy ∈ _DESCRIPTOR_AGENTS_RUNTIMES → gated out before the legacy chain, same dead-arm pattern removed for augment/trae in #2097). - Removed isCodebuddy from all 4 destructure sites (now comments only, mirroring the #2096 isAntigravity fold). Zero live isCodebuddy reads remain. UPGRADE 1 (extended hook bus): populate extendedHookEvents with the full extended set SubagentStop/Stop/PreCompact/SubagentStart (qwen #2092 / kimi precedent — codebuddy previously had extendedHookEvents:[] so it got NONE of these). The generic applySettingsJsonHooks loop wires them, so CodeBuddy's settings.json now gains all four subagent-lifecycle + stop/compact hooks it previously lacked, matching Qwen/Kimi coverage. No source change (the HOOK_EVENT_SURFACES SDK catalog is a locked dict; all 4 events are already in the validator enum; hookEvents already 'claude'). settings.json is golden- excluded → no golden change. UPGRADE 2 (background dispatch): surfaced via the negotiated capability contract only. CodeBuddy's dispatch.background:true legitimately exceeds the declarative- cli baseline (false) and survives negotiation with no warning. NO agent-file frontmatter field is emitted: the CodeBuddy CLI (GSD's install target, ~/.codebuddy/agents/) has NO background-dispatch frontmatter field — background is a caller-side run_in_background invocation param (verified against codebuddy.ai/docs/cli/sub-agents); the issue's agentMode/enabledAutoRun are IDE-only (codebuddy.cn, a different product). Emitting them would be a non- functional false-green, so it is deliberately not done. Golden: byte-identical for all 16 runtimes (folds are console/failures-report only; UPGRADE 1 → golden-excluded settings.json; UPGRADE 2 → no artifact change). Tests: declarative-reference-codebuddy (adapter/axes/fail-closed negotiation + AC2 source-grep guard) + codebuddy-upgrades (live install asserts all 4 extended hooks wired; dispatch.background survives negotiation above baseline). Matrix + install-on-your-runtime updated; changeset (Changed). capability-registry regenerated. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Changeset Fragments
This directory holds per-PR CHANGELOG fragments. Every PR with user-facing changes drops one (or more) <random-name>.md files here describing its CHANGELOG entry. Fragments are consolidated into the top-level CHANGELOG.md at release time.
Why
Two PRs that both edit the ### Fixed block of CHANGELOG.md always conflict on merge — git can't pick a serialization order without human input. Two PRs that each add a fresh .changeset/<unique-name>.md never conflict because they don't share lines.
See #2975 for the full rationale.
Adding a fragment
node scripts/changeset/new.cjs \
--type Fixed \
--pr 1234 \
--body "fix the thing — explain the user-visible change in one sentence"
This writes .changeset/<adjective>-<noun>-<noun>.md with frontmatter and a body. Three random words → concurrent PRs don't collide.
Format
---
type: Fixed
pr: 1234
---
**`/gsd-foo` no longer drops trailing slashes** — explain the user-visible change.
Allowed type: values follow Keep a Changelog: Added, Changed, Deprecated, Removed, Fixed, Security.
Opting out
PRs that legitimately have no user-facing impact can add the no-changelog label. CI honors it. When unsure, add the fragment.
At release time
Promotion is automatic. The release workflow's finalize job runs:
node scripts/changeset/cli.cjs render --version vX.Y.Z --date YYYY-MM-DD --allow-empty
This reads every fragment, groups bullets by type:, replaces ## [Unreleased] with a new ## [vX.Y.Z] - YYYY-MM-DD block, opens a fresh ## [Unreleased] above, and deletes consumed fragments. The --allow-empty flag ensures a no-change release still gets a dated heading (with a _No notable changes._ placeholder). A subsequent verify step confirms the promotion landed correctly. Maintainers do not run this by hand.
Archived fragments
.changeset/archived/ holds fragments for already-shipped releases (≤ 1.3.1), retained for provenance. Their content was hand-curated into the dated ## [1.x.y] sections of CHANGELOG.md during the #690 backfill — they were never consumed by render. All changeset tooling enumerates .changeset/ non-recursively, so archived fragments are never picked up or rendered. Do not move them back to the top level.
