VS Code is a net-new EoS runtime that — unlike every prior migration — is NOT
CLI-installed (Marketplace/VSIX extension). It has zero runtime==='vscode'
branches in bin/install.js and stays that way (regression-guarded); it is driven
entirely through the negotiated imperative Host-Integration adapter.
Registry + validator (the hard part):
- capabilities/vscode/capability.json (role:runtime): full hostIntegration block
(imperative / palette / active vscode.lm model / engine hook bus /
sandboxed-storage / mcp transport / sandboxed-web runtime; dispatch nested,
maxDepth 5 per VS Code's documented subagent depth).
- capability-validator.cjs extended so a role:runtime capability can legitimately
declare "extension-distributed, no config directory": new configHome.kind:'none'
+ installSurface:'none' (+ GATE-A pairing + the parity maps), with localConfigDir
and configHome.name made conditional on kind!=='none'. All 18 runtimes still
validate; getDirName returns a distinct sentinel (not '.claude') for a no-config
runtime.
- The add-a-registry-runtime tax: NON_INSTALLABLE_RUNTIMES exemption in the
runtime-flags drift guard, vscode added to global-config-home SPECIAL_CASED,
EXPECTED_PROFILES.vscode='ide', and the config-adapter/derivation/pin-count
guards updated. No golden-install fixture, model-catalog, or CONFIGURATION rows
(vscode never enters allRuntimes).
Dispatch + extension surface:
- Fixed vscode/extension.js's createHub()-no-args bug (every dispatch was
UnknownCommand, masked by a vacuous reachability test) — now reuses the shared
dispatchGsdCommand subprocess-shim (Node/desktop); the reachability test is
tightened to assert real dispatch.
- Promoted the #1933 host binding to a shipped vscode/host-binding.js; activate()
now composes the model/hookBus/stateIO seams through it. Corrected the model
seam to VS Code's real API (vscode.lm.selectChatModels() -> model.sendRequest();
vscode.lm.sendRequest does not exist) so the binding actually composes on real
desktop VS Code instead of throwing.
- New vscode/browser.js Web Extension entry with ZERO Node APIs (the engine's
config/capability loading is Node-bound, so the web entry registers the surface
and directs full dispatch to the native MCP server — honestly documented).
- UPGRADE 1: GSD skills as native Language Model Tools (contributes.languageModelTools
+ vscode.lm.registerTool), invoke() dispatching through the hub.
- UPGRADE 2: native subagent dispatch wired onto #runSubagent /
chat.subagents.allowInvocationsFromSubagents (fail-soft on API availability,
maxDepth 5 enforced).
- vscode/package.json: browser entry, engines.vscode ^1.105, chatParticipants +
languageModelTools contributions; fixed a stale activationPoints->activationEvents
manifest key. Added "vscode" to the package files array.
Docs (## vscode matrix section) + changeset (Added).

Net-new EoS/pi installable runtime — purely additive (no prior runtime==='pi'
branches). pi is a bun-runtime programmatic-CLI whose /gsd command is registered
by a native ExtensionAPI extension and dispatches through the embedded engine.
Stage 1 (install plumbing):
- capabilities/pi/capability.json: full hostIntegration descriptor (imperative /
slash-programmatic / active-model / native-extension / bun) + hostBehaviors
{nativePlugin, pluginOnlyInstall}.
- --pi flag + interactive-menu renumber (All 17->18); pi added to RUNTIME_FLAG_IDS,
RUNTIME_LABELS, RUNTIME_META, allRuntimes/runtimeMap, model-catalog defaults.
- Install mirrors OpenCode: pi installs the gsd.cjs extension + the shared engine
payload (gsd-core + scripts + config markers) + the shared hooks bundle (spawned
by the extension at lifecycle events, like OpenCode's plugin). pluginOnlyInstall
EXCLUDES declarative command/agent/skill markdown, which pi has no host-read
surface for (its /gsd is programmatic). _installNativePluginIfDeclared (extracted
from the opencode-family path) copies pi/gsd.cjs -> ~/.pi/agent/extensions/gsd.cjs
(global) / .pi/extensions/ (local). pi added to package.json files.
- Golden: new pi.json (320 files: extension + engine + 27-file hooks bundle, no
markdown); the 16 other fixtures + claude-local change only by the shared
model-catalog hash line.
Stage 2 (real dispatch + upgrades):
- Shared dispatchGsdCommand() (shell-command-projection): bounded, no-throw
subprocess-shim to gsd-tools.cjs (the only full-surface dispatch path; no
in-process full-hub factory exists). Fixes pi/gsd.cjs's createHub()-no-args bug
(every dispatch was UnknownCommand) AND the identical bug in mcp-server.cts's
gsd_invoke_command, which a vacuous unknown-family-only test had masked (now has
a real dispatch regression test).
- pi/gsd.cjs: /gsd handler now (args, ctx) - tokenizes (quote-aware, via the
shipped hooks/lib/git-cmd.js) + dispatches real family/subcommand (not hardcoded
query/help); gsd_invoke gets a TypeBox (JSON-schema-fallback) parameters schema +
consumes params; getArgumentCompletions; before_provider_request active-model
steering (fail-open on null resolution); functional session_start /
before_agent_start / session_before_compact hook bridges (spawn the shipped GSD
hook scripts).
- EXTENSION_EVENT_SURFACES.pi expanded from ['tool_call'] to the full 30-event
vocabulary.
Docs (host-integration matrix + how-to) + changeset (Added).

Full API Coverage by Default — Opt Out, Never Opt In. A phase that integrates
an external API/SDK/service can no longer seal without a decided coverage matrix.
- src/api-coverage.cts: deterministic detector (compound verb+noun signal +
<Service> API/SDK surface; stopword-guarded; strips fenced code) + matrix
parse/validate/render with field-length caps.
- check api-coverage.verify-pre: blocking seal-time gate; phase arg resolved as
a token under .planning/phases/ only (traversal-neutralized); validates
COVERAGE.md or blocks iff a strong integration signal is detected and no
matrix exists; fail-closed when phases tree exists but phase unresolvable.
- capabilities/ai-integration: workflow.api_coverage_gate config key (default
true), plan:pre contribution, blocking verify:pre gate. Data-driven.
- gsd-core/workflows/verify-work.md: generic verify:pre gate dispatch.
- Tests: detector FP/FN + matrix validation + fast-check bijection; gate e2e.
Code+security review findings fixed (stopword FP, scope containment, pipe/cap
rejection, prompt-injection message hygiene).
- Regenerated registry/matrix/loop-host-contract/goldens/baseline + docs.
Closes#1562
Resolve the zcode test cascade exposed by gsd-test:
- model-catalog.json: add zcode runtimeTierDefaults (null tiers, matching the
other profile-marker-only runtimes) so KNOWN_RUNTIMES stays parity with allRuntimes.
- runtime-name-policy: add zcode to GLOBAL_CONFIG_HOME_FRAGMENTS (~/.zcode) so
getGlobalConfigHomeFragment stops falling through to the .claude default.
- installer-migration-install: add the zcode fresh-install contract (flat-skills,
no settings, no package.json — same shape as trae).
- golden-install-parity: capture the zcode fixture via a standalone generator
script (not node --test — the gate stays gsd-test).
- capability-matrix.md: regenerate so zcode appears as a first-party row.
Fluidify the remaining count-pinned guards so adding a runtime no longer trips a
hand-pinned snapshot: gemini-runtime-removed (flag count derives from the
registry), non-claude-runtimes-registry-derivation (golden list derived from the
registry).
* feat(#1928): remove sunset gemini cli runtime, redirect to antigravity
Google sunset Gemini CLI on 2026-06-18; Antigravity CLI is its official successor (already a first-class GSD runtime). Remove the gemini runtime from the enum (16->15), aliases, labels, config-home fragment, install path, converters (convertClaudeToGemini{Markdown,Toml,Agent}, convertSlashCommandsToGeminiMentions), capability descriptor, gemini-extension.json, RULESET.GEMINI.*, and the interactive menu (renumbered, no gap).
--gemini now prints an explicit deprecation notice citing the 2026-06-18 sunset and redirects to --antigravity (no silent alias, per the issue's Hyrum's-Law rejection). Antigravity is preserved throughout: its GEMINI.md contextFileName, .gemini/antigravity config home, the shared convertGeminiToolName/claudeToGeminiTools tool vocabulary, and the 'gemini' hookEvents dialect it declares. GEMINI.md retargeted as Antigravity's context file.

* chore(#1928): drop Gemini CLI from issue templates (review nit)
Removes the sunset Gemini CLI runtime from the two GitHub issue-template
runtime lists that the removal PR missed, per @davesienkowski's review nit:
- feature_request.yml: 'Applicable runtimes' checkbox (a user could otherwise
request a feature for a runtime GSD no longer supports)
- bug_report.yml: 'Runtime' dropdown + the stale ~/.gemini/settings.json
retrieval-help line
Leaves the post-removal templates fully consistent with the Antigravity redirect.

* feat(#1105): add external-job capability (SLURM scheduler-adapter producer half)
The async external-job consumer half (#1165) shipped long ago: the core loop
reads .planning/async-jobs/<job>.json manifests and treats a non-terminal one
as the legal external_job_waiting half-state. The PRODUCER half (#1164) was
the remaining unimplemented piece of #1105.
This adds the producer as a default-off capability:
- capabilities/external-job/ — capability.json (execute:wave:post -> executor,
plan:post -> planner contributions, external_job.* config keys, default-off)
+ fragments teaching runtime-budget classification and externalization.
- src/external-job.cts -> gsd-core/bin/lib/external-job.cjs — pure producer
module: SLURM state -> manifest-status map (no guessing), manifest
build/validate (versioned stability contract), sbatch/squeue/sacct parsers,
and a fail-closed manifest writer (refuses a second non-terminal job for a
plan_id already in flight; refuses to clobber a malformed manifest). fs/clock
seams for deterministic tests.
- scripts/slurm-adapter.cjs — operator CLI (submit/poll/show) wrapping bounded
sbatch/squeue/sacct subprocesses; surfaces manifest commands for confirmation
and never auto-runs them (trust boundary).
- tests/external-job.test.cjs — 23 behavioral + fast-check property tests.
- docs/reference/long-running-operations.md + docs/how-to/async-external-jobs.md.
- CONTEXT.md glossary entry for the External-job Capability.
- Regenerated capability-registry.cjs; pruned the now-stale test-file-count
allowlist entry (external-job is at the 2-file cap).
* chore(#1105): backfill PR number in changeset
* fix(#1105): sync capability artifacts + update registry shape-pin tests
gsd-test caught that adding the external-job capability requires its
dependent artifacts regenerated and its registry-shape drift absorbed:
- sync-manifest-versions: stamp 1.7.0-rc.2 into capability.json (was 1.0.0).
- gen-capability-matrix --write: regenerate docs/reference/capability-matrix.md.
- gen-inventory-manifest --write: regenerate docs/INVENTORY-MANIFEST.json.
- check-gap-analysis-plan-post-e2e: plan:post now has 1 contribution
(external-job planner fragment) instead of 0.
- execute-wave-post-gate-pipeline-e2e: execute:wave:post now has 2
contributions (mempalace + external-job) instead of 1.
* fix(#1105): regenerate capability-registry after version stamp
sync-manifest-versions re-stamped external-job/capability.json from
1.0.0 to 1.7.0-rc.2 after the last registry regeneration, leaving the
committed capability-registry.cjs stale (CI gen-capability-registry
--check failed). gsd-test masked this because its setup runs the full
'npm run build' (which regenerates the registry); CI's 'npm test'
pretest only runs build:lib.
Add a non-blocking, warn-only codebase-drift gate at plan:pre so a stale
STRUCTURE.md is surfaced before /gsd:plan-phase spawns the planner, instead
of being discovered mid-execution by the existing execute:wave:post gate.
Gated on a dedicated workflow.plan_drift_precheck toggle (default true),
independent of schema_drift_gate. Never blocks planning, never spawns the
mapper agent at plan time.
Review feedback (#1595):
- Use a documented conventional-commit type (feat, not enhance) per
CONTRIBUTING.md / gsd-validate-commit.sh.
- Normalize the plan_drift_precheck command references to the colon prose
form (/gsd:plan-phase, /gsd:map-codebase) to match plan-phase.md §5.65;
registry regenerated from capability.json.
- Make the test temp dirs hermetic: drain mkdtemp dirs in an after() hook
via the helpers.cleanup() budget (local/no-raw-rmsync-in-tests-compliant).

* feat(#1435): capability matrix (generated + drift-guarded) + trust-model doc consolidation
ADR-1244 Phase 6. Adds the capability matrix reference, generated FROM the committed registry so it
can never drift from the actual capability set:
- scripts/gen-capability-matrix.cjs (--write / --check); --check is a CI drift guard.
- tests/capability-matrix-sync.test.cjs (4 tests): drift guard, buildMatrix==committed, every cap
present, no placeholders.
- docs/reference/capability-matrix.md regenerated from the registry (release-stable: shows engines.gsd,
omits the lockstep per-cap version that would churn the file every release).
- Consolidated the duplicate trust-model doc: deleted docs/explanation/the-capability-trust-model.md,
merged its content into capability-trust-model.md, redirected ~10 references; no stale links remain.
- Diataxis verification (now that gsd capability is a real command): corrected the matrix's third-party
section — the matrix is the first-party catalogue; the overlay-aware view of installed third-party
capabilities is 'gsd capability list', not this generated file.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* fix(#1435): address code-review — non-vacuous matrix test + generator polish
- capability-matrix-sync.test.cjs: assert the 'security registers a ship:pre gate' precondition
unconditionally so the extension-point check can never degrade to a vacuous pass on registry drift.
- gen-capability-matrix.cjs: warn (stderr) on an unknown loop point at generation time; rename
enginesOf -> fmtEngines for consistency with the other fmt* helpers (output unchanged).
- capability-trust-model.md: point the two how-to links at the real files
(import-a-capability-from-a-url.md, version-a-capability.md) instead of the bare directory.
