Changed

Advanced toolkit version to 2026.11.11 across packages, locks, and registry files.
Removed default browser link underlines globally across landing components, documentation pages, and sidebar navigation.
Balanced dark/light theme contrast and synchronized localStorage theme tokens.
Renamed README-KH.md to README-KM.md.

2026.8.31 — 2026-08-31

Release 2026.8.31: upgrades app-builder with mandatory DESIGN.md gatekeeper, AI SDK/Chatbot patterns, Game developer routing, and template consistency.

Added

Embedded mandatory DESIGN.md (Design Source-of-Truth) gate into app-builder orchestration pipeline, scaffolding structure, and Next.js templates.
Added 2026 AI Application Pattern (Vercel AI SDK streaming, PostgreSQL pgvector, vector search, LLM API rate limiting) and SQL-first Drizzle ORM options in tech-stack.md.
Added project type detection for AI/Chatbot applications and Game applications (game-development skill routing).
Integrated automatic preview verification (auto_preview.py) into iterative enhancement and DevOps handoff.

Changed

Advanced toolkit version to 2026.8.31 across all packages.
Bumped app-builder skill version to 1.1.0.
Standardized globals.css path to src/app/globals.css across Next.js templates.
Fixed Express API template dependencies to include @prisma/client in dependencies and prisma as devDependency.
Updated the mcp-builder skill for the stable MCP specification.
Reworked orchestrator and parallel-agents guidance around Antigravity-native agents and tasks.

Security

Added required safeguards for external $ref resolution, schema-validation resource limits, untrusted tool annotations, and execution isolation.
Added explicit trust boundaries for repository content, MCP responses, tool annotations, web content, logs, and subagent outputs.
Added finite agent, delegation-depth, turn/retry, timeout, cancellation, and no-progress controls to prevent recursive delegation and indefinite ReAct loops.

2026.7.27 — 2026-07-26

Patch release: the CLI no longer exits silently when run through an npm bin symlink (global install or npx).

Fixed

CLI exited silently when invoked through an npm bin symlink: entry path is now realpath-resolved before direct-run guard comparison.

Added

Regression test running the CLI through a bin-style symlink.

2026.7.26 — 2026-07-26

Production candidate for the Antigravity-first runtime: native discovery, MCP planning, safety hooks, orchestration, deterministic plugin packaging, diagnostics, migration guidance, and release gates.

Added

Antigravity runtime contract, Doctor, native hook schemas, MCP synchronization helper, plugin builder, and regression tests.
Production guides, migration and rollback instructions, security threat model, and production checklist.

Changed

Google Antigravity is the primary supported runtime for AG Kit.
Root, CLI, web, and toolkit versions are aligned at 2026.7.26.
Plugin inventory generation is deterministic and the managed integrity lock covers runtime and hook files.

Security

A narrow PreToolUse gate blocks high-confidence destructive root and raw-disk commands without replacing Antigravity permission controls.
MCP synchronization remains explicit, refuses placeholder credentials, preserves conflicts by default, and creates backups before writes.

2026.7.18 — 2026-07-18

Managed .agents components with SemVer, deterministic dependency registry and lock, generated orchestration graph, memory contracts, and drift-proof validation.

Added

SemVer metadata for all agents, skills, workflows, and rules.
Machine-readable manifest.json and SHA-256 manifest.lock.json.
Generated workflow-to-agent-to-skill dependency graph.
JSON schemas and standardized memory topic files.
Registry and graph generators with CI-safe check modes.

Changed

Self-validation now enforces dependency compatibility, generated-file synchronization, and memory contracts.
Root, CLI, web, and toolkit versions are aligned at 2026.7.18.

2026.7.10 — 2026-07-10

Toolkit self-validator, shared runner, offline dependency hygiene analyzer, bundle-size analyzer, and regression/correctness fixes across agents, schemas, and configurations.

Fixed

Made mcp_config.json valid JSON.
Corrected invalid YAML frontmatter in lint-and-validate and design-rules.
Added missing allowed-tools contract to intelligent-routing.
Fixed verify_all.py using an uninitialized results variable.
Fixed toolkit-root discovery and URL argument routing in validation runners.
Removed orchestration deadlocks caused by mandatory missing plan/CODEBASE files.
Prevented the security scanner from flagging its own regex definitions.
Made high/critical security findings return a failing exit code.

Added

Shared validation runner with JSON reporting and duration/error capture.
Offline dependency hygiene analyzer.
Build bundle-size analyzer.
Toolkit self-validator for configuration, frontmatter, links, references, inventory, and Python syntax.
Root quick-start guide and runtime-script documentation.

2026.6.29 — 2026-06-29

Design module overhaul: replaced in-house design skill with taste-skill framework, added frontend-architecture skill, and introduced mandatory DESIGN.md design-token gate before any UI work.

Added

design-spec skill + DESIGN.md gate: machine-readable design-token format (YAML schema, type system, section order).
design-spec/collection.md: 70+ real-world DESIGN.md references (Airbnb, Stripe, Linear, Vercel, Apple) the workflow reads before authoring.
frontend-architecture skill: code-organization rules for React/Next and Vue (separation of concerns, state tiers, API services).

Changed

frontend-design rebuilt on taste-skill: brief inference, design dials, design-system map, em-dash ban, pre-flight checks.
Skill count synced to 45 across architecture catalogs.

2026.5.13 — 2026-05-13

Project rebrand to AG Kit, calendar versioning, and orchestration/memory skills.

Added

Code Review Graph skill: token-efficient code review using Tree-sitter AST graphs and MCP blast-radius analysis.
AG Kit Vantage console design identity, typography tokens, and visual assets.

Changed

Switched releases from semantic versioning to calendar versioning (YYYY.M.D).
Rebranded to AG Kit across package metadata, READMEs, docs, templates, scripts, and workflows.
