2.1.3 Code-Review Features

Hook execution timeout has been increased from 60 seconds to 10 minutes (600 seconds).

The 2.1.3 release unified skill/command terminology, extended hook timeouts to 10 minutes, added release-channel toggling, and fixed seven system bugs affecting external drives, background tasks, sub-agent models, and terminal rendering.

Features Tested

The test ran January 16, 2026, verifying three features and seven bug fixes via code review and changelog analysis. Three major features landed: hook timeout increased from 60 seconds to 600 seconds (10 minutes), enabling long-running setup scripts and database migrations without interruption; release channel toggle in /config allowing users to switch between stable (production-ready) and latest (pre-release) branches; and merged / commands and skills into a single mental model, eliminating dual documentation and terminology confusion.

What the Test Found

All 10 changes passed code review. Bug fixes addressed: false duplicate-skill detection on ExFAT file systems (common on external drives); plan files not cleared by /clear command; inaccurate background task counters; sub-agents and web search incorrectly falling back to wrong model tiers during compaction; trust dialog failures from home directory context; and terminal rendering instability from ANSI sequence edge cases.

Runtime-Test Status

The test was inconclusive via runtime: changelog analysis and source inspection verified all changes, but runtime validation skipped long-timeout hooks (would require 60+ second execution to prove the timeout actually extends) and UI-dependent features (/config channel toggle, command palette). The assessment remains code-review confidence, not operational proof.

Impact

Hook timeout extension unblocks CI/CD setup, rate-limited API polling, and batch file processing in hooks. The stable/latest toggle enables gradual rollout strategy (dev on latest, production on stable). Bug fixes improve external-drive portability, command predictability, cost tracking in sub-agents, and terminal reliability.
