Automated signed Copilot SDK bump.

  • @github/copilot-sdk: 1.0.19-preview.0 → 1.0.20-preview.2
  • Bundled runtime (copilotCliVersion): 1.0.95-0 → 1.0.96-2
  • Base: main @ a5aeadabe1ee5b1c2bf70e9e61706f4e7b684282
  • Opened by workflow run

Draft until validation passes and any fixer changes are approved for the exact PR head. The sdk-vscode-bump-fix agent first iterates on Linux PR checks (up to 10 cycles), then on the authoritative full product build (up to 5 cycles).

Each product build triggered for this PR is posted as a comment below with a link.

Published package layout changes

Copilot published package layout diff

Best-effort path comparison from npm pack --dry-run; runtime 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.

@github/copilot-sdk 1.0.19-preview.0 → 1.0.20-preview.2

No published path changes.

@github/copilot-sdk-darwin-x64 1.0.19-preview.0 → 1.0.20-preview.2

  • Root cause: SDK 1.0.20-preview.2 bundles runtime 1.0.96-2, whose intentional schema transforms preserve the write_agent root oneOf constraint in the tool description and extend the managed permissions.limitTo contract; committed snapshots still described runtime 1.0.95-0.
  • Changes: Refreshed the managed-settings schema snapshot and all 19 deterministic Copilot model prompt snapshots; no product, packaging, or build logic changed.
  • Tests: Snapshot regeneration passed 25 tests, then the canonical local gate passed source policy, full client typecheck, full compile, Agent Host conformance, all Copilot provider E2E suites, prompts, managed settings, and SDK provider integrations.
  • Disposition: approved for authoritative PR-check and product-build validation on the new exact head.

Warning

Firewall blocked 1 domain

The following domain was blocked by the firewall during workflow execution:

  • api.github.com

[!TIP]
api.github.com is blocked because GitHub API access uses the built-in GitHub tools by default. Instead of adding api.github.com to network.allowed, use tools.github.mode: gh-proxy for direct pre-authenticated GitHub CLI access without requiring network access to api.github.com:

tools:
  github:
    mode: gh-proxy

See GitHub Tools for more information on gh-proxy mode.

To allow these domains, add them to the network.allowed list in your workflow frontmatter:

network:
  allowed:
    - defaults
    - "api.github.com"

See Network Configuration for more information.
