Automated update of @github/copilot to version 1.0.64-0.

Changes

  • Updated @github/copilot in nodejs/package.json and test/harness/package.json
  • Re-ran all code generators (scripts/codegen)
  • Formatted generated output
  • Updated Java codegen dependency, POM property, and regenerated Java types

Java Handwritten Code Adaptation Plan

If java-sdk-tests CI fails on this PR, follow these steps:

  1. Identify failures: Run mvn clean, mvn verify from java/ locally or check the java-sdk-tests workflow run logs.
  2. Categorize errors:
    • Constructor signature changes (new fields added to generated records)
    • Enum value additions/renames in generated types
    • New event types requiring handler registration
    • Removed or renamed generated types
  3. Fix handwritten source (java/src/main/java/com/github/copilot/sdk/):
    • Update call sites passing positional constructor args to include new fields (typically null for optional new fields).
    • Update switch/if-else over enum values to handle new cases.
    • Register handlers for new event types in CopilotSession.java if applicable.
  4. Fix handwritten tests (java/src/test/java/com/github/copilot/sdk/):
    • Same constructor/enum fixes as above.
    • Add new test methods for new functionality if the change adds user-facing API surface.
  5. Validate: cd java && mvn clean test-compile jar:jar && mvn verify -Dskip.test.harness=true
  6. Format: cd java && mvn spotless:apply
  7. Push fixes to this PR branch.

To automate this, trigger the java-adapt-handwritten-code-to-accept-upgrade-changes agentic workflow instead.

Pull request overview

Updates the mono-repo to @github/copilot 1.0.64-0 and regenerates all schema-derived artifacts across the supported SDKs (Node/TS, Python, Go, .NET, Rust, Java). This pulls in new/updated wire surfaces such as persisted binary tool results (binaryResultsForLlm), the session.binary_asset event, and new experimental “discovery paths” RPCs for agents/skills/instructions.

Changes:

  • Bumped @github/copilot to ^1.0.64-0 in Node packages used by the SDK, samples, and test harness.
  • Regenerated protocol/session-event types across languages (new events/types + updated field visibility/optionality).
  • Updated Java codegen dependency + regenerated Java types and RPC stubs to match the new schema.

The 1.0.64-0 runtime removed report_intent; when the model still calls it,
the runtime replies 'Available tools that can be called are <list>.' That
list contains platform-specific shell tool names (powershell/read_powershell/
... on Windows, bash/read_bash/... on Linux/macOS), which broke snapshot
matching across CI platform legs.

Add a normalizeAvailableToolNames tool-result normalizer that maps the shell
tool family names in that error list to stable placeholders (\,
\, \, \, \), applied
symmetrically to stored snapshots and incoming requests. Re-normalize the 45
affected snapshots accordingly so they match on all platforms.

Comment thread nodejs/test/e2e/hooks_extended.e2e.test.ts
stephentoub and others added 6 commits June 17, 2026 07:59
With vision off, the model cannot see the image and flails by running a
shell command to verify the file exists. The recorded command was the
PowerShell-only Test-Path, which fails on Linux/macOS bash (command not
found, exit 127), breaking snapshot replay on those CI legs.

Replace it with the cross-platform 'echo True', which yields identical
normalized output (True, exit 0) on both PowerShell and bash, so the
snapshot replays on all platforms. The test's purpose (verifying image_url
presence/absence in traffic) is unaffected.

The test asked the model to run three FK-dependent INSERTs. The model issued
them as three parallel sql tool calls; their execution order is not
deterministic, so on some platforms the todo_deps INSERT raced ahead of its
parent todos rows and hit 'FOREIGN KEY constraint failed', diverging from the
recorded snapshot (cache miss on macOS CI).

Reword the prompt to ask for a single sql tool call containing all three
statements in order. Statements within one call run sequentially, so the FK
constraint is always satisfied and the snapshot replays deterministically on
all platforms. Re-recorded the snapshot accordingly. Verified stable across
3 replay runs.

Port the Node test-code changes to Go and regenerate Go-specific
permission snapshots for the runtime that removed the report_intent tool:

- hooks_extended: postToolUse modifiedResult now drives the built-in
  `view` tool instead of report_intent (matches the shared, already
  regenerated snapshot); postToolUseFailure is skipped (built-in tools
  are unavailable when hooks restrict availableTools under 1.0.64-0).
- session_todos_changed: align the prompt with the regenerated shared
  snapshot (single sql tool call with all three statements in order).
- permissions: write-operations snapshot copied from the fresh Node
  recording (identical prompt); shell-commands prompt aligned to a
  cross-platform `echo test` conversation with a fresh snapshot.

Mirrors the Go fixes (acb410f) across the remaining SDKs after runtime
change #10303 removed the report_intent tool:

- hooks_extended modifiedResult test: drive postToolUse via the built-in
  view tool instead of report_intent (remove availableTools restriction,
  relax assertion to case-insensitive "done"). [.NET, Python, Rust]
- postToolUseFailure test: skip/ignore; built-in tools are unavailable
  when hooks restrict availableTools, so the failure path can't be
  exercised under 1.0.64-0. [.NET, Python, Rust]
- session_todos_changed: align prompt to the deterministic single-call
  wording so it matches the regenerated shared snapshot. [.NET, Python,
  Rust, Java]
- permissions: refresh Java-named snapshots (async_permission_handler,
  resume_session_with_permission_handler, tool_call_id_in_permission_requests)
  from the regenerated Node equivalents (identical prompts).

- rust/tests/e2e/hooks_extended.rs: apply nightly rustfmt (shortening the
  tool name to "view" lets the closure collapse onto one line).
- python: split the long todos PROMPT into implicit string concatenation
  to satisfy ruff E501 (line <= 100); string content is byte-identical.
- dotnet: keep the postToolUseFailure Skip reason on a single line to
  match the existing codebase convention and dotnet format.

Test-name sanitization differs across SDKs, so .NET/Rust/Java consume
differently-named snapshot files than Node/Go/Python for the same hooks
tests. Those files still recorded the removed report_intent tool's
"Intent logged" success result. Overwrite them with the fresh
new-runtime recordings (report_intent -> "does not exist"):

- invoke_both_hooks_for_single_tool_call.yaml (Java)
- should_invoke_both_pretooluse_and_posttooluse_hooks_for_single_tool_call.yaml (.NET/Rust)
- invoke_pre_tool_use_hook_when_model_runs_a_tool.yaml (Java)
- invoke_post_tool_use_hook_after_model_runs_a_tool.yaml (Java)

The 1.0.64-0 runtime removed report_intent, so the model's recorded
report_intent call now resolves to "does not exist". That fires a
preToolUse hook but no postToolUse hook, so the strict
assert_eq!(pre.1, post.1) (first pre tool == first post tool) breaks
because the first pre hook is report_intent while the first post hook
is view.

Collect all pre/post tool names and assert a tool appears in both,
matching the tolerant assertion the Go reference test already uses.

✅ Cross-SDK Consistency Review

This PR updates @github/copilot from 1.0.63 → 1.0.64-0 and regenerates all SDK generated code. All 6 SDKs (Node.js/TypeScript, Python, Go, .NET, Java, Rust) are consistently updated.

New API Surface — Present in All SDKs

Feature Node.js Python Go .NET Java Rust
session.binary_asset event + SessionBinaryAssetData
maxInlineBinaryBytes in session create/update options
agents.getDiscoveryPaths RPC
instructions.getDiscoveryPaths RPC
skills.getDiscoveryPaths RPC
AgentDiscoveryPath / InstructionDiscoveryPath / SkillDiscoveryPath types
ProviderConfigType / ProviderConfigWireApi enums

Language-Specific Adaptations (Expected)

  • Java CopilotClient.java: Adds null for the new maxInlineBinaryBytes positional parameter — appropriate handwritten call-site update.
  • Python rpc.py: Adds SessionFSReaddirWithTypesEntryType as a backward-compat alias for SessionFsReaddirWithTypesEntryType — necessary to avoid a breaking change from the generator's capitalization update.
  • Go scripts/codegen/go.ts: Renames the type JSON field to Discriminator in Go structs to avoid shadowing the Type() SessionEventType interface method — appropriate Go-specific fix.

No consistency gaps found. The PR correctly keeps all SDKs in sync with the updated schema.
