Summary

Adds typed client support for GitHub's Agent Tasks REST API.

This implements the documented public-preview Agent Tasks endpoints:

  • GET /agents/repos/{owner}/{repo}/tasks
  • POST /agents/repos/{owner}/{repo}/tasks
  • GET /agents/repos/{owner}/{repo}/tasks/{task_id}
  • GET /agents/tasks
  • GET /agents/tasks/{task_id}

Closes #4213.

Changes

  • Added AgentTasksService and registered it on Client.
  • Added Agent Tasks request/response types for tasks, sessions, artifacts, list options, and create options.
  • Added methods for listing, creating, and retrieving agent tasks.
  • Added tests covering:
    • endpoint paths
    • HTTP methods
    • request bodies
    • response parsing
    • query parameters
    • pagination
    • preview API headers
  • Added OpenAPI operation metadata for the new preview endpoints.
  • Regenerated accessors and iterators.

Notes

The Agent Tasks API is currently in public preview, so this PR keeps the implementation scoped to the fields and endpoints currently documented by GitHub.

Validation

Ran the repository validation flow from CONTRIBUTING.md:

  • script/fmt.sh
  • script/test.sh ./...
  • script/lint.sh
  • script/generate.sh
  • git diff --check

script/test.sh with the default race configuration could not run on this Windows machine because cgo/gcc was not available. I reran the full test script with the non-race fallback across all modules, and it passed.

@stevehipwell @alexandear updated, thanks for the reviews.

Changes in the latest update:

  • adjusted the Agent Tasks response structs so documented required fields are non-pointers, while nullable/optional fields remain pointers
  • folded the private list helper back into List and removed the Codecov-only List bad-options test so the production code stays simpler
  • added agentTasksAPIVersion and replaced the repeated WithVersion("2026-03-10") usage
  • updated the Agent Tasks doc comment URLs so the apiVersion value matches the request version
  • regenerated the affected accessors/tests

Validation:

  • script/generate.sh passed
  • gofmt passed on changed Go files
  • go test ./github passed
  • script/fmt.sh passed
  • script/test.sh ./... passed
  • script/lint.sh passed
  • git diff --check passed
  • confirmed openapi_operations.yaml and go.mod have no diff
  • confirmed changed files are LF-only with no CRLF churn

@alexandear @stevehipwell Thanks for pointing me to the right direction.

Root cause was generator-side: the Agent Tasks documentation URLs did not include an explicit apiVersion, so the metadata normalizer defaulted the generated comments to 2022-11-28.

I added a narrow metadata mapping for /rest/agent-tasks/agent-tasks so generated Agent Tasks doc links normalize to apiVersion=2026-03-10, then reran script/generate.sh. The generated comments now stay aligned with agentTasksAPIVersion.

Validation:

  • script/generate.sh passed and preserved the corrected Agent Tasks comments
  • go test ./github passed
  • go test ./metadata from tools passed
  • script/lint.sh passed
  • git diff --check passed
  • confirmed openapi_operations.yaml and go.mod have no diff
  • confirmed changed files are LF-only with no CRLF churn

I think we can create separate structs for the Data instead of using the raw json.RawMessage:

                              data:
