Fold all runtime==='kimi'/isKimi logic branches into descriptor-driven hostBehaviors (localInstallDeferred, verificationStyle, agentManifestStyle, reapplyCommand, doneBannerStyle) + add 'kimi' to _DESCRIPTOR_AGENTS_RUNTIMES. Kimi's skills/kimi-agents dispatch was already descriptor-driven (converter-by- name + kimi-agents kind). Zero isKimi/runtime==='kimi' branches remain. UPGRADE 1 (native hook bus): new hooksSurface 'kimi-hooks-toml' + a marker- delimited config.toml [[hooks]] emitter (buildKimiHooksTomlBlock/writeKimiHooksToml in runtime-hooks-surface.cts; resolveKimiHooksTomlDir in runtime-homes.cts). GSD's lifecycle hooks now wire into Kimi's native ~/.kimi/config.toml (Context7- confirmed path) at SessionStart/PreToolUse/Stop/PreCompact/SubagentStart/ SubagentStop — kimi becomes a hooks/ consumer (the 3 && !isKimi exclusion guards removed). config.toml holds absolute install paths so it's golden-excluded via an exact relative-path (.kimi/config.toml), not a basename (which would blind Codex's config.toml). New hooksSurface value added to the closed enum in capability-validator + runtime-config-adapter-registry. UPGRADE 2 (background dispatch): flip dispatch.backgroundDispatch true (Kimi's Agent tool takes run_in_background; root agent already gets the Agent tool), so negotiation no longer flattens dispatch. subagentToolkit stays 'undocumented' per AC (coder/explore/plan have distinct tool policies). MCP transport explicitly deferred (no installer-driven MCP for any runtime). Golden: only kimi.json changes (hooks/ scripts now installed); all 15 others + claude-local byte-identical (kilo/zcode keep their own exclusions). Tests: kimi-imperative-reference (adapter/axes/fail-closed/hostBehaviors + source-grep guard) + kimi-upgrades (config.toml [[hooks]] SessionStart + marker idempotency + backgroundDispatch negotiation). CONTEXT.md glossary + matrix + how-to 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.
