* feat(#1681): ADR-1239 Phase C-2 — gsd-mcp-server bin entry + lifecycle test [slice 3b] Phase 4 slice 3b (closes #1681). The companion MCP server bin entry so any MCP-consuming host connects via 'npx gsd-mcp-server' (or its bin on PATH) and gets GSD command (point 1) + state IO (point 5) with no bespoke plugin. - gsd-core/bin/gsd-mcp-server.cjs: #!/usr/bin/env node shim requiring ./lib/mcp-server.cjs + runServer({stdin, stdout}); non-zero exit on fatal error (justified n/no-process-exit disable). Mirrors gsd-tools.cjs. - package.json: add 'gsd-mcp-server' bin entry. - tests/gsd-mcp-server-bin.test.cjs: 3 process-lifecycle tests — initialize + tools/list round-trip + clean exit, malformed-line -> parse error + server keeps running, empty stdin -> clean exit. Synchronous spawnSync (bounded; server exits on stdin EOF, no orphan). Phase 4 trust-gate (#1806) + loader wiring (#1808) + server module (#1809) + this bin/lifecycle slice = all of #1681's deliverables. Concrete host binding -> Phase 5 (#1682). npm-integrity + eslint + security + inventory all clean. * docs(#1681)+chore(changeset): how-to for the companion MCP server + Added fragment docs/how-to/connect-gsd-mcp-server.md — Diataxis how-to guide for connecting any MCP-capable host to gsd-mcp-server: goal-oriented flow (add config → restart → verify), real-world per-host conditionals, troubleshooting, and a trimmed reference table. Explanation/reference linked out (ADR-1239, capability-trust- model) per Diataxis boundary rules rather than mixed in. .changeset/humble-seals-rest.md — type: Added (first user-reachable surface of the epic: a new bin command). The how-to doc satisfies the docs-required gate. * fix(#1681): move gsd-mcp-server shim to top-level bin/ (out of the runtime-copied tree) The shim at gsd-core/bin/gsd-mcp-server.cjs was inside the tree the installer copies into every runtime config dir, so it leaked into all 16 runtimes and broke golden-install-parity. The MCP server is a PACKAGE bin the host spawns (npx gsd-mcp-server), not a per-runtime artifact — so it belongs at top-level bin/ alongside install.js (which is also never copied into a runtime config). - gsd-core/bin/gsd-mcp-server.cjs -> bin/gsd-mcp-server.js (require path now ../gsd-core/bin/lib/mcp-server.cjs). - package.json: bin entry -> bin/gsd-mcp-server.js. - tests/gsd-mcp-server-bin.test.cjs: SHIM path updated. - eslint.config.mjs: add bin/gsd-mcp-server.js to the bin/install.js block (drops the n/no-process-exit disable — the n plugin isn't loaded for that block, so the disable referenced an undefined rule). golden-install-parity 16/16 restored; lifecycle + unit tests green; eslint 0; lint:ci all ok.
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.
