Release channels

This document follows the Stable channel. Each skill carries a chip showing the release it first shipped in — the latest, NEW · v2.20.0, is highlighted.

Stablelatest

main branch — Production-ready, fully tested — ck update

Betabeta

dev branch — Pre-release, may have rough edges — ck update --beta (excluded here)

Official changelog

Stable releases, newest first. Pre-release work on the beta (dev) channel is omitted.

v2.20.0

2026-06-18
  • New skills: ghpm (GitHub project management — issues, Projects boards, handoffs), html-video (HTML/CSS/JS → MP4), vibe (full vibe-coding pipeline), review-pr (formal gh review with --reply + anti-ai-slop reference).
  • chrome-profile — real Chrome profile workflow, replacing the deleted chrome-devtools.
  • ck:plan — drops time estimates; adds AgentWiki publish flag + HTML/GitHub output modes.
  • git PR merge automation; ship publishes journals to AgentWiki; watzup cross-branch handoff scanner with ranked next steps.
  • shopify modernized to current shopify.dev (GraphQL-first + safe init wrapper); brainstorm gains --html wiki & problem-first modes.
  • Hooks — workflow artifact gate, canonical wiring overhaul, managed-hooks manifest for deterministic self-heal. Human MCP disabled by default; code-review red-team wording made policy-safe.

v2.19.0

2026-05-13
  • Skill gates — scout-first, exact-requirements, and no-side-effects enforced on shipped skills.
  • Generated context hooks disabled by default.

v2.18.0

2026-05-12
  • New skill: tech-graph (vendored fireworks-tech-graph) — semantic code analysis.
  • ck:predict --chain reason/probe; ck:scenario iterative saturation; ck:security red-team personas; ck:autoresearch reframed as a family router.
  • agent-browser refactored to a discovery stub; mermaidjs-v11 SVG layout reference routed to tech-graph.
  • Removals: chrome-devtools and template-skill deleted; kanban + mcp-management duplicates absorbed into use-mcp.

v2.17.0

2026-04-28
  • New skills: agentize (codebase → CLI + MCP server), ai-multimodal (multi-provider image routing), cti-expert, excalidraw, graphify, show-off, xia; stitch per-project isolation.
  • worktree --base to override the auto-detected base branch; deep + TDD plan-cook workflows.
  • Skill schema contract + format-compliance gate; 82 skill descriptions hardened.

v2.16.0

2026-04-03
  • Statusline overhaul — config-driven modular architecture, quota reset countdown, custom color themes, user-defined layout, cache-first startup.
  • Session-state moved to global storage (no project-dir pollution); per-project .ckignore overrides for scout-block.
  • ai-multimodal env key resolution + 5xx retry; stitch SDK fixes + auto quota tracking; worktree --no-prefix / --help; useGemini default → false.

v2.15.0

2026-03-29
  • worktree --no-prefix flag to skip branch prefix and preserve case.
  • (v2.15.1: release tooling only — beta workflow + Discord notification fixes.)

v2.14.0

2026-03-28
  • New skills: retro, llms, deploy, project-organization, loop, scenario, predict, security, stitch, security-scan, ship, design (consolidated logo/CIP/slides/banner/icon).
  • fix v2.0 — structured Scout → Diagnose → Assess → Implement → Verify pipeline; team v3.0.0 on the current Claude Code Agent API.
  • code-review always-on adversarial review (4 input modes, scope gating); preview --html with diff / plan-review / recap modes + theme toggle.
  • Hooks — session-state persistence + strategic compaction + structured diagnostics logging; 3-tier eval infrastructure for skills and agents.

v2.13.0

2026-02-25
  • ck: namespace prefix — every skill name is prefixed with ck: to avoid collisions with Claude Code built-ins.
  • argument-hint field added to all skills for better discoverability.
  • Namespace cleanup and cross-reference fixes across the kit.
  • chrome-devtools evaluate fix.

v2.12.0

2026-02-05
  • Agent Teams v2.1.0 — rewritten as a CK-native imperative execution engine. Auto-executing templates, event-driven hooks (TaskCompleted, TeammateIdle), agent memory persistence.
  • Portable manifest — Codex AGENTS.md → .codex/agents/ migration support.
  • /ck:plan red-team — adversarial plan review with hostile reviewer lenses.
  • Commands → Skills — every command is now a skill; /ck: syntax unchanged.
  • New skills: team, plan, bootstrap, test, project-management, mintlify. New agent: Code Simplifier.
  • Native Task orchestration for fix / code-review / scout / debug; skill-creator Skillmark support; Chrome DevTools headless detection + OAuth.

v2.11.0 – v2.11.3

2026-02-20 → 21
  • Always-on diagnostics logging — crash wrappers on every hook for automatic error capture.
  • Scout-block hardening — broad glob detection (**/*.ext), heredoc-aware path extraction, compound-command & allowlist edge cases, path normalization.
  • Windows: reduced terminal freeze from excessive process spawning.
  • Added hotfix: commit type; Discord embed field-limit & empty-changelog guards.

v2.10.0

2026-02-05
  • Focused Reader 2.0 — redesigned markdown-novel-viewer.
  • Plan validation propagation — auto-propagate validation decisions to phase files.
  • Visual generation modes — /ck:preview --explain --slides --diagram --ascii.
  • cook-after-plan-reminder hook; code-review edge-case scouting; language-aware naming hook; monorepo worktree paths.
Releases prior to v2.10.0 live on the GitHub Releases page. Beta (dev-channel) builds are intentionally excluded from this stable reference.
