Replace PreToolUse hook-based question tool blocking with the existing
tools parameter approach (tools: { question: false }) which physically
removes the tool from the LLM's toolset before inference.
The hook was redundant because every session.prompt() call already passes
question: false via the tools parameter. OpenCode converts this to a
PermissionNext deny rule and deletes the tool from the toolset, preventing
the LLM from even seeing it. The hook only fired after the LLM already
called the tool, wasting tokens.
Changes:
- Remove subagent-question-blocker hook invocation from PreToolUse chain
- Remove hook registration from create-session-hooks.ts
- Delete src/hooks/subagent-question-blocker/ directory (dead code)
- Remove hook from HookNameSchema and barrel export
- Fix sync-executor.ts missing question: false in tools parameter
- Add regression tests for both the removal and the tools parameter
- fix(delegate-task): return error on poll timeout instead of silent null
- fix(delegate-task): ensure toast and session cleanup on all error paths with try/finally
- fix(delegate-task): apply agent tool restrictions in sync-prompt-sender
- fix(plugin): add symmetric idle dedup to prevent double hook triggers
- fix(cli): replace regex-based JSONC editing with jsonc-parser in auth-plugins
- fix(cli): abort event stream after completion and restore no-timeout default
All changes verified with tests and typecheck.
