Automated signed Copilot dependency bump.

@github/copilot: 1.0.81-0 → 1.0.81-3
Base: main @ 0dac2a8dfdad732e464a588028ac89cdb55cb988
Opened by workflow run

Draft until validation passes. The sdk-vscode-bump-fix agent will prime packaging changes from the canary insights and iterate on failures.

Copilot published package layout diff

Best-effort path comparison from npm pack --dry-run; CLI platform paths use representative x64 packages for macOS, Linux, and Windows. Content-only and architecture-specific changes are left to the product build. This is not an availability gate.

🔧 sdk-vscode-bump-fix status (cycle 1)

Root cause (regression class: intentional runtime contract change). The bumped @github/copilot CLI (1.0.81-3) now prepends a one-turn <tools_changed_notice> block to the next user message when a tool is withdrawn mid-session — here exit_plan_mode is removed after the plan is approved. The Agent Host E2E capi-replay test "planning-mode session-state writes are auto-approved in default mode" failed on Windows(X64) and macOS(ARM64) with model request #5 does not match the recorded request in the fixture, because the live request #5 carried the notice while the recorded fixture did not. Confirmed runtime-authored (prompts/cli_user::tools_changed_notice, sibling to working_directory_changed / additional_directories_changed), not VS Code product code.

Fix. Elided the runtime-injected change-notice blocks (tools_changed_notice, working_directory_changed, additional_directories_changed) symmetrically in the capi-replay projection (modelRequestProjection.ts), so both recorded and live user messages compare equal. These blocks are environment/timing-derived, not host-authored structure, matching the existing elision policy for tool-result payloads, runtime ids, and paths. No fixture regeneration; no build/packaging/signing changes.

SDK+CLI correlation. CLI-only bump. SDK on branch 1.0.11 declares CLI range ^1.0.79 (floor 1.0.79) per sdk-compatibility.md — this bump's CLI 1.0.81-3 is in range, so no paired-SDK bump is required. The failing canary threads use a different CLI (1.0.81-canary.*); their native-payload verdicts do not apply to this exact signed pair.

Product-build state. Pushed harness fix; awaiting the next sdk-vscode-bump-validate product build for authoritative validation.> Generated by sdk-vscode-bump-fix · opus48 · 324.6 AIC · ⌖ 23.4 AIC · ⊞ 18K · ◷

🔧 sdk-vscode-bump-fix status (cycle 2)

Root cause (regression class: intentional runtime contract change). The bumped @github/copilot CLI (1.0.81-3) changed the MCP client-capability contract: the runtime now advertises the MCP sampling capability to a plugin MCP server only when the session has a live consumer registered for the sampling.requested event. VS Code drives sampling exclusively through rpc.mcp.executeSampling (App→host (redacted) channel), which no longer implicitly counts as a consumer. Without a registered interest, plugin servers received McpError -32603: ... sampling is not supported by this client, so server.createMessage()threw. The Agent Host E2E test *"plugin MCP sampling cancellation returns to the model"* failed on all platforms because the tool-result carried the McpError string instead of the expectedMCP_SAMPLE:The user cancelled the request.. Confirmed against runtime source: native_session.rs derive_client_capabilitiesgatessamplingonactive_session_has_event_interest(session_id, "sampling.requested"), and rpc.rsdocuments that long-polling SDK clients must explicitlyregisterInterest` for each gated event type.

Fix. In copilotAgentSession.ts, register interest in sampling.requested (session.rpc.eventLog.registerInterest({ eventType: 'sampling.requested' })) during initializeSession and release the returned handle on dispose (guarded for the race where the session is disposed mid-registration). Scoped to sampling — the only capability failing this build. No fixture regeneration; no build/packaging/signing changes.

SDK+CLI correlation. CLI-only bump. SDK on branch 1.0.11 declares CLI range ^1.0.79; this bump's CLI 1.0.81-3 is in range, so no paired-SDK bump is required. Failing canary threads use a different CLI (1.0.81-canary.*); their native-payload verdicts do not apply to this exact signed pair — this is a genuine integration contract change VS Code must adopt.

Local validation. Full typecheck-client OOMs in this sandbox; a scoped tsc over copilotAgentSession.ts reports no errors on the changed code (the SDK rpc.eventLog.registerInterest/releaseInterest types match the existing rpc.mcp.executeSampling access path). The e2e replay test requires a full product build + live runtime, deferred to the authoritative build.

Product-build state. Pushed the product fix; awaiting the next sdk-vscode-bump-validate product build for authoritative validation.> Generated by sdk-vscode-bump-fix · opus48 · 754.9 AIC · ⌖ 23.7 AIC · ⊞ 18K · ◷

The @github/copilot 1.0.81-3 runtime now advertises the MCP `sampling` client capability to plugin MCP servers only when the session has a live consumer registered for the `sampling.requested` event. VS Code drives sampling via rpc.mcp.executeSampling, which no longer implicitly counts as a consumer, so plugin servers were told "sampling is not supported by this client" and createMessage() failed. Register interest explicitly on session init and release it on dispose. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
