v2.1.292
Claude Code — Releases · Oct 6, 2026
Claim: Claude Code v2.1.292 release: adds marketplace install flag, effort parameter for agents, prompt caching for mods, backoff delay tuning, and numerous bug fixes across security, file handling, and session management.
Evidence: Detailed changelog listing specific features (--marketplace flag, effort parameter to Agent tool, CLAUDE_CODE_OVERLOADED_RETRY_BASE_DELAY_MS env var, prompt.autocomplete event, prompt caching in $.model.complete), security fixes (file read permissions, UNC path handling, PreToolUse hook bypasses), and operational fixes (session resumption, background command cleanup, vim mode, etc.).
Rationale
This is a routine maintenance/bug-fix release for Claude Code (a tool Timothy already uses in his workflow). The changelog is detailed and technical but offers no quantified performance gains, new architectural patterns, or stack-defining capabilities. The effort parameter for subagents and prompt caching for mods are incremental improvements; the RETRY_BASE_DELAY_MS env var is useful for token-economy tuning but not transformative. Security fixes and session-management repairs are operational necessities, not innovation. Composition specificity is low because the changes are within Claude Code's existing surface; applicability is moderate because Timothy runs CC+Codex, but no claim suggests this cuts token spend or reshapes the workflow. Durability is moderate — these fixes and features survive model upgrades. Source credibility remains 3 (official release notes from a credible source), and no reason to downgrade.
