* feat(cli): add CRUD, pub/sub, and API gateway templates for micro new
Add --template flag to 'micro new' with three preset templates:
- crud: CRUD service with Create/Read/Update/Delete/List, in-memory
store with sync.RWMutex, UUID generation, pagination, and doc
comments with @example tags for MCP tool discovery.
- pubsub: Event-driven service with Publish/Stats RPCs and a
Subscribe method that hooks into the broker. Includes event
types with ID, type, source, data, and timestamp.
- api: API gateway service with Health and Endpoint RPCs, an
internal HTTP route table, and a response recorder for
proxying requests through RPC.
All templates include MCP-ready doc comments and work with
--no-mcp. The default template (no flag) is unchanged.
Usage:
micro new myservice --template crud
micro new myservice --template pubsub
micro new myservice --template api
* fix(ai): update Atlas Cloud provider to use actual API formats
Fix the Atlas Cloud image generation to use their real async API:
POST /api/v1/model/generateImage → poll /api/v1/model/prediction/{id}
instead of the OpenAI-compatible endpoint which doesn't exist.
Add Quality and OutputFormat fields to ai.ImageRequest for
provider-specific image parameters.
Update default text model from llama-3.3-70b (doesn't exist) to
deepseek-ai/DeepSeek-V3-0324 (their flagship model). Update
default image model to openai/gpt-image-2/text-to-image.
* feat(website): add AI-generated images to landing page, docs, and blog
Generate 5 images via Atlas Cloud's image API (gpt-image-2) to
elevate the website experience:
- hero.png: microservices network graph for landing page
- architecture.png: registry + broker architecture diagram
- mcp-agent.png: AI agent calling services via MCP
- developer-experience.png: terminal showing micro run/chat
- blog-atlas.png: Atlas Cloud unified API illustration
Add visual sections to the landing page with architecture,
MCP integration, and developer experience showcases. Add
images to docs index, MCP docs, and Atlas Cloud blog post.
All images resized to 1200px wide and optimized for web.
Generated using Atlas Cloud sponsor credits.
* feat(website): redesign landing page and add images to docs
Redesign the landing page from a centered card layout to a
full-width modern site with:
- Top navigation bar
- Hero section with gradient background and CTA buttons
- Full-width image showcase sections
- Two-column layout for architecture, MCP, and DX sections
- Feature grid with 6 capabilities
- Footer with links
- Responsive breakpoints for mobile
Generate 3 more images via Atlas Cloud for docs:
- getting-started.png for the getting started guide
- deployment.png for the deployment guide
- data-model.png for the data model docs
Add images to getting-started.md, model.md, and deployment.md.

* feat(ai): add ImageModel interface with Atlas Cloud and OpenAI support
Add ai.ImageModel interface for text-to-image generation alongside
the existing ai.Model for text. Uses the same options pattern
(WithAPIKey, WithBaseURL) and the same provider registration
system (RegisterImage/NewImage).
Implement GenerateImage for Atlas Cloud and OpenAI providers via
the OpenAI-compatible /v1/images/generations endpoint. Default
image model is gpt-image-1. Responses return images as URL,
base64, or both depending on the provider.
Update Atlas Cloud blog post and integration guide with image
generation examples. Update ai/README.md with ImageModel docs.
* fix(website): widen docs content by reducing layout max-width to 1100px
Remove the 800px max-width on .content (which left empty space on
the right) and reduce the overall .layout and footer from 1400px
to 1100px. With the 230px sidebar this gives ~830px of content
width — readable and fills the page properly on desktop.
* feat(ai): add History for multi-turn conversation state
Add ai.History — a lightweight message accumulator that tracks
user prompts, assistant replies, and tool call/result pairs
across turns. FIFO truncation when message count exceeds the
configured limit. System prompt is passed through on every
Generate call.
Wire History into micro chat so conversations are multi-turn by
default (limit 50 messages). Add 'reset' command to clear
history mid-session.
5 unit tests covering accumulation, truncation, reset, snapshot
isolation, and tool call recording.

* docs: add AI provider integration guide and Supported AI Providers section
Add a step-by-step guide for AI infrastructure companies to implement
ai.Model and contribute a provider to go-micro. Covers the full
lifecycle: skeleton, tool call handling, tests, registration, and PR
checklist.
Add a "Supported AI Providers" section to the project README that lists
current providers (Anthropic, OpenAI) in a table and links to the
integration guide with a call-to-action for new providers and sponsors.
Streamline the "Adding a New Provider" section in ai/README.md to point
to the new guide instead of duplicating a full code listing.
* fix: remove nonexistent Discord link from README
* fix(website): set content container width to 800px on desktop
Move the 800px max-width from .markdown-body up to .content so
the entire content pane (not just the inner body) is sized
correctly. The container now fills up to 800px beside the sidebar.
* feat(ai): wire Atlas Cloud into server and auto-detection
Import atlascloud provider in the micro server so it is available
when running micro run / micro server. Add atlascloud to
AutoDetectProvider so --ai_base_url with an atlascloud domain
selects the right provider automatically.
* feat(ai): add Google Gemini provider
Add ai/gemini implementing ai.Model for Google's Gemini API. Uses
the native generateContent endpoint with system_instruction,
contents/parts, and functionDeclarations — not an OpenAI shim.
Default model gemini-2.5-flash, auth via x-goog-api-key header.
Wire into micro server imports and AutoDetectProvider (matches
googleapis.com and google in base URL).
Update README.md and ai/README.md with provider listing.
* feat(ai): add Groq, Mistral, and Together AI providers
Add three new OpenAI-compatible providers:
- ai/groq: ultra-fast inference, default model llama-3.3-70b-versatile
- ai/mistral: Mistral AI, default model mistral-large-latest
- ai/together: Together AI, default model Llama-3.3-70B-Instruct-Turbo
All three are wired into the micro server imports and
AutoDetectProvider. README and ai/README updated with the full
provider table.
* feat(ai): add ai/tools helper and 'micro chat' interactive agent
Extract the registry-discovery + RPC-execution loop from the web
agent playground into a reusable ai/tools package:
- tools.New(reg) creates a Set bound to a registry
- Set.Discover() walks the registry and returns []ai.Tool with
LLM-safe (underscored) names, remembering the mapping back to
the original dotted form
- Set.Handler(client) returns an ai.ToolHandler that resolves
the safe name and issues the RPC
Add cmd/micro/chat — an interactive 'micro chat' REPL that uses
ai/tools to let users talk to their services through any
registered AI provider. Supports --prompt for single-shot use,
auto-detects the provider from --base_url, and falls back to the
provider's conventional env var (ANTHROPIC_API_KEY, etc).
Update README with the new command and the programmatic example.
* feat(examples): add gRPC interop example
Add examples/grpc-interop showing that any standard gRPC client can
call a go-micro service — no go-micro SDK required on the client
side. Includes:
- proto/greeter.proto with generated Go, gRPC, and micro stubs
- server/ using go-micro gRPC transport
- client/ using stock google.golang.org/grpc (no go-micro imports)
- README with Python example and explanation of how routing works
Addresses the confusion from issue #2818 where users didn't know
that go-micro gRPC services are callable by any gRPC client.
* fix: strip /api prefix from MCP routes
Change /api/mcp/tools and /api/mcp/call to /mcp/tools and
/mcp/call. MCP is a first-class feature, not a sub-path of the
API proxy. Update server routes, playground template, scopes
template, run.go output, README, CLI README, and all docs.

* feat: add agent platform showcase and blog post
Add a complete platform example (Users, Posts, Comments, Mail) that
mirrors micro/blog, demonstrating how existing microservices become
AI-accessible through MCP with zero code changes.
Includes blog post "Your Microservices Are Already an AI Platform"
walking through real agent workflows: signup, content creation,
commenting, tagging, and cross-service messaging.
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* refactor: rename handler types to drop redundant Service suffix
UserService → Users, PostService → Posts, CommentService → Comments,
MailService → Mail. Matches micro/blog naming convention.
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* refactor: consolidate top-level directories, reduce framework bloat
Move internal/non-public packages behind internal/ or into their
parent packages where they belong:
- deploy/ → gateway/mcp/deploy/ (Helm charts belong with the gateway)
- profile/ → service/profile/ (preset plugin profiles are a service concern)
- scripts/ → internal/scripts/ (install script is not public API)
- test/ → internal/test/ (test harness is not public API)
- util/ → internal/util/ (internal helpers shouldn't be imported externally)
Also fixes CLAUDE.md merge conflict markers and updates project
structure documentation.
All import paths updated. Build and tests pass.
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* refactor: redesign model package to match framework conventions
Rename model.Database interface to model.Model (consistent with
client.Client, server.Server, store.Store). Remove generics in
favor of interface{}-based API with reflection.
Key changes:
- model.Model interface: Register once, CRUD infers table from type
- DefaultModel + NewModel() + package-level convenience functions
- Schema registered via Register(&User{}), no per-call schema passing
- Memory implementation as default (in model package, like store)
- memory/sqlite/postgres backends updated for new interface
- protoc-gen-micro generates RegisterXModel() instead of generic factory
- All docs, blog, and README updated

Add examples/agent-demo with a multi-service project management app
(projects, tasks, team) that demonstrates AI agents interacting with
Go Micro services through MCP. Includes seed data and example prompts.
Add blog post 4 "Agents Meet Microservices: A Hands-On Demo" walking
through the example code and showing cross-service agent workflows.
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* feat: enable multiple services in a single binary
Remove global state mutations from service and cmd option functions so
that configuring one service no longer overwrites another's settings.
Key changes:
- service/options.go: remove all DefaultXxx global writes from option
functions; newOptions() now creates fresh Server, Client, Store, and
Cache per service while sharing Registry, Broker, and Transport
- cmd/cmd.go: newCmd() uses local copies instead of pointers to package
globals; Before() no longer mutates DefaultXxx vars
- cmd/options.go: remove global mutations from all option functions
- service/service.go: export ServiceImpl type for cross-package use
- service/group.go: new Group type for multi-service lifecycle
- micro.go: add Start/Stop to Service interface, expose Group and
NewGroup convenience function
- examples/multi-service: working example with two services
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* docs: highlight multi-service binary support
Add multi-service section to README with code example, update features
list, add to examples index, and note in status summary.
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* feat: unify service API and clean up developer experience
- Unified service creation: micro.New("name", opts...) as canonical API
- Clean handler registration: service.Handle(handler, opts...) accepts
server.HandlerOption args directly, no need to reach through Server()
- Unexported serviceImpl: users interact through Service interface only
- Service groups use Service interface (not concrete type)
- Fixed Stop() to properly propagate BeforeStop/AfterStop errors
- Fixed store init: error-level log instead of fatal on init failure
- Updated all examples to use consistent patterns
- Updated README, getting-started, MCP docs, and guides
- Added blog post about the DX cleanup
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc

* refactor: rename model/ package to ai/ for AI model providers
The model/ package name conflicted with the conventional use of "model"
for data models. Renamed to ai/ which better describes the package's
purpose (AI provider abstraction for Anthropic, OpenAI, etc.) and frees
up model/ for future data model layer use.
- Rename model/ → ai/ with package name change
- Update all Go imports from go-micro.dev/v5/model to go-micro.dev/v5/ai
- Update cmd/micro/server/server.go references (model.X → ai.X)
- Update all documentation and roadmap references
- All tests pass, CLI builds successfully
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* feat: add model package for typed data access with CRUD and queries
New model/ package provides a typed data model layer using Go generics.
Supports structured CRUD operations, WHERE filters, ordering, pagination,
and automatic schema creation from struct tags.
Three backends:
- memory: in-memory for development and testing
- sqlite: embedded SQL for dev and single-node production
- postgres: full PostgreSQL for production deployments
Key features:
- Generic Model[T] with Create/Read/Update/Delete/List/Count
- Query builder: Where(), WhereOp(), OrderAsc/Desc(), Limit(), Offset()
- Struct tags: model:"key" for primary key, model:"index" for indexes
- Auto table creation from struct schema
- 19 tests passing across memory and sqlite backends
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* feat: add model code generation to protoc-gen-micro
Extend the micro plugin to generate model structs from proto messages
annotated with // @model. Generated alongside client/server code in
the same .pb.micro.go file.
For a proto message like:
// @model
message User { string id = 1; string name = 2; }
Generates:
- UserModel struct with model:"key" and json tags
- NewUserModel(db) factory returning *model.Model[UserModel]
- UserModelFromProto(*User) *UserModel converter
- (*UserModel).ToProto() *User converter
Supports @model(table=custom_table, key=custom_field) options.
Adds GetComments() to generator for plugin comment inspection.
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* feat: add Model() to Service interface for Client/Server/Model trifecta
Every service now exposes Client(), Server(), and Model() — call services,
handle requests, and save/query data from the same interface. Includes
README docs, blog post, and a full model guide on the docs site.
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* feat: add Helm chart for MCP gateway Kubernetes deployment
Adds official Helm chart at deploy/helm/mcp-gateway/ with:

- HPA for auto-scaling based on CPU/memory
- Ingress with TLS support
- Configurable registry (consul, etcd, mdns), rate limiting,
JWT auth, audit logging, and per-tool scopes
- Security context (non-root, read-only rootfs, drop all caps)
- NOTES.txt with post-install connection instructions
Updates roadmap and status docs to reflect Helm Charts as delivered.
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* docs: add Helm chart entry to changelog
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* feat: add per-tool circuit breakers to MCP gateway
Protects downstream services from cascading failures. When a tool's
RPC calls fail repeatedly, the circuit opens and rejects requests
immediately until the service recovers (half-open probe pattern).
- CircuitBreakerConfig with MaxFailures, Timeout, MaxHalfOpen
- Per-tool breakers created during service discovery
- Integrated into HTTP call path with 503 response when open
- Records success/failure after each RPC call
- --circuit-breaker and --circuit-breaker-timeout CLI flags
- 8 unit tests covering all state transitions

* feat: enable multiple services in a single binary
Remove global state mutations from service and cmd option functions so
that configuring one service no longer overwrites another's settings.
Key changes:
- service/options.go: remove all DefaultXxx global writes from option
functions; newOptions() now creates fresh Server, Client, Store, and
Cache per service while sharing Registry, Broker, and Transport
- cmd/cmd.go: newCmd() uses local copies instead of pointers to package
globals; Before() no longer mutates DefaultXxx vars
- cmd/options.go: remove global mutations from all option functions
- service/service.go: export ServiceImpl type for cross-package use
- service/group.go: new Group type for multi-service lifecycle
- micro.go: add Start/Stop to Service interface, expose Group and
NewGroup convenience function
- examples/multi-service: working example with two services
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* docs: highlight multi-service binary support
Add multi-service section to README with code example, update features
list, add to examples index, and note in status summary.
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* feat: unify service API and clean up developer experience
- Unified service creation: micro.New("name", opts...) as canonical API
- Clean handler registration: service.Handle(handler, opts...) accepts
server.HandlerOption args directly, no need to reach through Server()
- Unexported serviceImpl: users interact through Service interface only
- Service groups use Service interface (not concrete type)
- Fixed Stop() to properly propagate BeforeStop/AfterStop errors
- Fixed store init: error-level log instead of fatal on init failure
- Updated all examples to use consistent patterns
- Updated README, getting-started, MCP docs, and guides
- Added blog post about the DX cleanup
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* fix: add blog post 5 to blog index
Blog post 5 (Developer Experience Cleanup) existed as a file but was
missing from the blog index page.
https://claude.ai/code/session_01GkduEhcrqcG45rdfYh8dAc
* feat: make micro new generate MCP-enabled services by default
- main.go template includes mcp.WithMCP(":3001") by default
- Handler template has agent-friendly doc comments with @example tags
- Proto template has descriptive field comments
- README includes MCP usage, Claude Code config, and tool description tips
- Makefile adds mcp-tools, mcp-test, mcp-serve targets
- go.mod updated to Go 1.22
- Added --no-mcp flag to opt out of MCP integration
- Post-create output shows MCP endpoint URLs

* Address code review: use crypto/rand for trace IDs, fix var redecl, remove dup comment
Co-authored-by: asim <17530+asim@users.noreply.github.com>
* Rename Playground to Agent, fix styling, add LLM-powered prompt
- Rename /playground to /agent, move Agent link to top of sidebar menu
- Fix template styling: use existing form/input/button CSS from styles.css
instead of inline styles and form-plain class
- Add /api/agent/settings GET/POST endpoints for model API key, model
name, and base URL configuration (stored in server store)
- Add /api/agent/prompt POST endpoint that sends user prompt to
OpenAI-compatible LLM API with tool definitions from registry,
executes any tool calls via RPC, and returns results with a
follow-up LLM summary
- Show available tools in a table using existing table styles
- Prompt section is placed above settings for primary workflow

* Address code review: handle unmarshal errors, extract system prompt, improve param descriptions
Co-authored-by: asim <17530+asim@users.noreply.github.com>
* Add Anthropic model support to the agent
Support both OpenAI and Anthropic APIs in the agent prompt handler:
- Add provider selector (OpenAI/Anthropic) to settings UI and backend
- Auto-detect provider from base URL when not explicitly set
- Anthropic: use /v1/messages endpoint, x-api-key header, input_schema
format for tools, content blocks for responses, tool_use/tool_result
message format for follow-ups
- OpenAI: unchanged /v1/chat/completions with Bearer auth
- Default models: gpt-4o (OpenAI), claude-sonnet-4-20250514 (Anthropic)
- Provider-specific defaults for base URLs

Implement Q2 2026 roadmap items for AI-native microservices:
MCP stdio transport:
- JSON-RPC 2.0 over stdio for Claude Code integration
- Methods: initialize, tools/list, tools/call
- Auto-detection: stdio (no address) vs HTTP/SSE (with address)
micro mcp command:
- 'micro mcp serve' - start MCP server (stdio or HTTP)
- 'micro mcp list' - list available tools
- 'micro mcp test' - test a tool (placeholder)
- Enables Claude Code users to add microservices as tools
Gateway refactor:
- Created gateway/api package (reusable, 150 lines)
- Moved gateway logic from cmd/micro/server/gateway.go
- HandlerRegistrar pattern for flexibility
- cmd/micro/server/gateway.go now compatibility wrapper (72 lines)
- 50% code reduction, better separation of concerns
- Library users can now use gateway in custom apps
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Major Features:
- Unified gateway architecture (micro run + micro server use same code)
- MCP (Model Context Protocol) integration as library package
- AI-accessible microservices with 3 lines of code
Gateway Unification:
- Created reusable gateway module (cmd/micro/server/gateway.go)
- Updated micro run to use unified gateway (removed duplicate code)
- Conditional authentication (disabled in dev, required in prod)
- Reduced code duplication, simplified maintenance
MCP Integration:
- New library package: gateway/mcp
- Automatic service discovery → MCP tools
- HTTP/SSE transport support (stdio coming soon)
- Works for both library users and CLI users
- CLI flags: --mcp-address for micro run and micro server
Documentation:
- ADR-010: Unified Gateway Architecture
- CLI & Gateway Guide for users
- MCP Gateway README and examples
- Blog post: Making Your Microservices AI-Native with MCP
Breaking Changes: None (fully backward compatible)

* Add systemd-based deployment support
- micro init --server: Initialize server to receive deployments
- Creates /opt/micro/{bin,data,config} directories
- Generates systemd template unit (micro@.service)
- Creates 'micro' system user
- micro deploy: Deploy services via SSH + systemd
- Builds linux/amd64 binaries automatically
- Copies via rsync/scp to server
- Manages services via systemctl
- Helpful error messages for common issues
- micro status --remote: Check remote service status
- micro logs --remote: Stream remote logs via journalctl
- micro stop --remote: Stop services on remote server
- Config: Added 'deploy' blocks to micro.mu for named targets
The deployment model:
- systemd is the process supervisor (battle-tested)

micro build:
- Default: builds Go binaries to ./bin/
- Cross-compile with --os and --arch
- Docker is optional via --docker flag
micro deploy:
- Requires --ssh user@host
- Copies pre-built binaries (if ./bin/ exists)
- Or syncs source and builds on remote
- No Docker dependency
Go binaries are self-contained. No runtime needed.

micro run now starts an HTTP gateway alongside your services:
- Web dashboard at http://localhost:8080
- API proxy at /api/{service}/{method}
- Health checks at /health
- Service listing at /services
The experience is now:
$ micro new helloworld
$ cd helloworld
$ micro run
Open http://localhost:8080 to see and call your services.
New flags:
--address :3000 # Custom gateway port
--no-gateway # Disable gateway (services only)
Updated documentation to make this the central experience.

- Add micro.mu DSL and micro.json config file support
- Implement hot reload with file watching (--no-watch to disable)
- Start services in dependency order (topological sort)
- Environment management (--env flag, MICRO_ENV var)
- Health check waiting before starting dependents
- Graceful shutdown in reverse dependency order
Config file example (micro.mu):
service users
path ./users
port 8081
service posts
path ./posts
port 8082
depends users
env development
STORE_ADDRESS file://./data
Closes#2828

* fix: remove deprecated rand.Seed calls
Go 1.20+ automatically seeds the global random number generator.
These calls are no-ops and generate warnings with newer Go versions.
Removed from:
- selector/strategy.go
- registry/cache/cache.go
- broker/memory.go
- broker/http.go
- cmd/cmd.go
- transport/memory.go

* fix: handle previously ignored errors
- MySQL store: properly handle prepared statement errors in initDB()
- Consul registry: handle client creation errors in Client() method
These silent failures could cause hard-to-debug issues in production.

* feat(genai): improve provider interface with context and streaming
Breaking changes:
- Generate() and Stream() now require context.Context as first parameter
- Stream.Close() added for proper resource cleanup
Improvements:
- Proper context support for cancellation and timeouts
- Real SSE streaming for OpenAI and Gemini text generation
- Better error handling with wrapped errors and API error responses
- Thread-safe provider registry with sync.RWMutex
- New options: WithMaxTokens, WithTemperature, WithTimeout
- Stream has proper Close() method for cleanup
- Results can include Error field for per-chunk errors
Provider updates:
- OpenAI: true streaming with SSE parsing, proper HTTP client with timeout
- Gemini: true streaming with streamGenerateContent endpoint
- Default model updated to gpt-4o-mini (OpenAI) and gemini-2.0-flash (Gemini)

* feat(tls): make TLS secure by default, configurable via environment
BREAKING: TLS now verifies certificates by default. Set MICRO_TLS_INSECURE=true
to restore previous behavior (NOT recommended for production).
Changes:
- Add util/tls.Config(), SecureConfig(), InsecureConfig(), ConfigFromEnv() helpers
- Update all components to use ConfigFromEnv() instead of hardcoded InsecureSkipVerify
- Set MinVersion to TLS 1.2 for all TLS configs
Affected components:
- broker/http
- broker/rabbitmq
- registry/etcd
- registry/consul
- transport/grpc
This improves security posture while allowing opt-out for development environments.
Co-authored-by: Shelley <shelley@exe.dev>
* feat(tls): add TLS helpers with opt-in secure mode
NOT a breaking change - keeps InsecureSkipVerify=true as default for
local development compatibility.
New util/tls helpers:
- Config() - returns config based on MICRO_TLS_SECURE env var
- SecureConfig() - certificate verification enabled
- InsecureConfig() - certificate verification disabled (dev only)
For production security, use one of:
- Set MICRO_TLS_SECURE=true with proper CA-signed certs
- Use a service mesh (Istio, Linkerd) for automatic mTLS
- Configure TLSConfig directly with your certificates
Also: Changed CLI alias from 'g' to 'gen' for clarity
- micro generate handler -> micro gen handler
Co-authored-by: Shelley <shelley@exe.dev>
* refactor(cli): rename generate directory to gen for consistency
Directory name now matches the command alias:
cmd/micro/cli/gen/ -> micro gen handler
