Evidence (public sources, summarized; not reproduced by this contributor):
- https://code.claude.com/docs/en/agent-sdk/troubleshooting (official_docs, 2026-09, documented_behavior): Troubleshooting maps 'Native CLI binary for <platform>-<arch> not found' to skipped optional dependencies and the other two messages to missing/inaccessible paths.
- https://code.claude.com/docs/en/agent-sdk/typescript (official_docs, 2026-09, documented_behavior): TypeScript reference: SDK bundles native binary as optional dependency; bun build --compile can't resolve it inside $bunfs and throws the same message; extractFromBunfs() copies it out; one platform per executable.

Problem details
- Observed symptom
- Agent works locally but fails in CI/Docker image or in a bun-compiled single executable.
- Context
- Product: Claude Agent SDK Component: TypeScript SDK bundled CLI resolution Operation: query() in @anthropic-ai/claude-agent-sdk Affected versions: unknown Environment: unknown Packages: @anthropic-ai/claude-agent-sdk unknown Trigger: The SDK bundles the CLI as an optional dependency (e.g. @anthropic-ai/claude-agent-sdk-linux-x64); installs with --omit=optional/--no-optional or lockfiles from another platform skip it. In bun --compile executables require.resolve can't see the $bunfs virtual FS.

solution · Revision 1
Proposed fix: [Claude Agent SDK TypeScript] 'Native CLI binary for <platform>-<arch> not found' — optional platform package skipped, or bun build --compile ($bunfs)
Recommended action: Reinstall without skipping optional deps (matching platform), or set pathToClaudeCodeExecutable to a native install; for bun --compile embed the platform package and use extractFromBunfs().
Option: Ensure the platform package is installed [evidence: official_recommended_action]
Applies when: Claude Agent SDK / TypeScript SDK bundled CLI resolution
Steps:
1. npm ci without --omit=optional on the target platform
2. Or set pathToClaudeCodeExecutable
3. For bun --compile import the platform package and call extractFromBunfs()
Expected: Request accepted / failure becomes diagnosable
