Fold remaining isKilo logic branches into descriptor-driven reads: finishPermissionWriter (uninstall cleanup), skipSharedHooksInstall (hooks copy), and a skills converter-name registry (the artifactLayout.converter field is now load-bearing, not decorative). frontmatterDialect stays the documented dispatch key for frontmatter (no descriptor field for it). Dead isKilo destructure bindings removed. Byte-identical golden parity for all 16 runtimes (opencode, which shares kilo's combined-family path, verified clean). UPGRADE 1 (hook bus): install .kilo/plugins/gsd-core.js native plugin + extensionEvents:"kilo" + EXTENSION_EVENT_SURFACES.kilo (OpenCode-fork bus). UPGRADE 2 (active model): populate runtimeTierDefaults.kilo + thread modelOverride through convertClaudeToKiloFrontmatter — model no longer stripped from agents. UPGRADE 3 (MCP): document the gsd-core MCP companion under kilo's mcp config key. UPGRADE 4 (named dispatch): agents/*.md mode:subagent roster is the Task-tool dispatch surface (tested); subagentToolkit stays 'undocumented' per AC so dispatch degrades to 'degraded' by design. Model-catalog single-source edit ripples the shared model-catalog.json hash into all 16 golden fixtures (expected). Inline defect fixes (no-defer): stale- bake-guard resolveAgentDir 'agent'->'agents' (was a silent no-op for opencode/ codex), hardcoded 'Removed OpenCode plugin' uninstall log -> generic, and the connect-gsd-mcp-server.md OpenCode mcpServers->mcp doc error. Tests: kilo-imperative-reference (adapter/axes/fail-closed/degradation/ hostBehaviors + widened isKilo source-grep across 4 modules) + kilo-upgrades (plugin parity+load, model-override converter, agents dispatch surface, MCP doc). Matrix + how-to + config docs updated; changeset added. 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.
