Manages Go development tools using the Go 1.24+ tool directive in go.mod. Use when adding linters, generators, or dev tools to Go projects, running project-specific tools, integrating tools with go:generate, or migrating from tools.go patterns.

Operate the official grafana/mcp-grafana server from an agent. Use when the conversation has Grafana MCP tools available and you need to query Prometheus/Loki/Pyroscope, search or edit dashboards, manage alert rules, or generate Grafana deeplinks. Covers tool selection, parameter conventions (datasource UID, time ranges, limits, query types), and context-saving patterns for dashboard work.
Analyzes an existing ISUCON-style application, designs an optimal infrastructure and architecture redesign that respects every ISUCON rule, and emits the proposal as a self-contained Agent Skill that another Claude session can read and execute. Use when starting an ISUCON contest or practice, drafting a contest-day architecture plan before touching code, or when the user asks to "design the architecture", "plan the topology", or "produce an implementation skill" for an ISUCON problem.
Decomposes the apply-skill produced by designing-isucon-architecture into atomic tasks, materializes one Claude Code subagent per task, and emits a dispatcher slash command that fires the subagents in dependency order (parallel where the graph allows). Use when an applying-isucon-arch-<slug> skill exists and the team wants the architecture rollout to run as orchestrated subagent jobs rather than a single linear human-driven session, or when the user asks to "create subagents for this ISUCON design", "wire the ISUCON apply-skill into Claude Code agents", or "split the rollout into parallel agent tasks".
Runs Visual Regression Testing (VRT) locally to prevent disqualification in Web Speed Hackathon. Captures screenshots, compares against baselines, updates snapshots, and validates visual integrity after performance optimizations. Use when optimizing WSH apps, running VRT checks, updating VRT baselines, or investigating VRT failures.
Analyzes a Web Speed Hackathon project, researches each improvement topic in depth, stores research as Agent Skills, and generates executable Claude Code commands for each optimization. Use when starting WSH optimization, creating an optimization roadmap, or generating executable improvement commands.
Ports an ISUCON-style Rust reference implementation to Go (Echo) using parallel subagents. Use when the contest provides a Rust reference but the team wants to compete in Go, or when the user asks to migrate a Rust web app to Go Echo endpoint by endpoint. Preserves API URI, request/response shape, frontend static files, the isuwari reboot/retest daemon, and the isuadmin account exactly as distributed (changing them = disqualification).

| description | Manages Go development tools using the Go 1.24+ tool directive in go.mod. Use when adding linters, generators, or dev tools to Go projects, running project-specific tools, integrating tools with go:generate, or migrating from tools.go patterns. |
Manage project-specific development tools in Go 1.24+ using the tool directive. Ensures consistent tool versions across team members and CI/CD environments.
Use this skill when adding dev tools (linters, generators, formatters) to Go projects, running tools via go tool, integrating with go:generate, or migrating from legacy tools.go patterns.
Supporting files: COMMANDS.md for full command reference, MIGRATION.md for migration patterns, ADVANCED.md for dependency isolation and caching.
Add a tool to your project:
go get -tool golang.org/x/tools/cmd/stringer@latest
This adds to go.mod:
tool golang.org/x/tools/cmd/stringer
Run the tool:
go tool stringer -type=MyType
# Add with latest version
go get -tool github.com/golangci/golangci-lint/cmd/golangci-lint
# Add with specific version
go get -tool honnef.co/go/tools/cmd/staticcheck@v0.5.1
# Run by short name
go tool staticcheck ./...
# List all available tools
go tool
# Show binary path
go tool -n stringer
# Update specific tool
go get -tool honnef.co/go/tools/cmd/staticcheck@v0.6.0
# Update all tools to latest
go get tool
go get -tool golang.org/x/tools/cmd/stringer@none
Use go tool in generate directives for reproducible code generation:
//go:generate go tool stringer -type=Level
//go:generate go tool mockgen -source=service.go -destination=mocks/service.go
Run with:
go generate ./...
.PHONY: lint audit generate
lint:
go tool golangci-lint run ./...
audit:
go vet ./...
go tool staticcheck ./...
go tool govulncheck ./...
generate:
go generate ./...

go mod verify: Validate checksums after adding tools-modfile for tools with conflicting dependenciestool directiveTool not found after install:
# Verify it's in go.mod
go list tool
# Check if go version is 1.24+
go version
Version conflict with application: Use separate modfile (see ADVANCED.md):
go tool -modfile=tools/go.mod <toolname>
CI/CD caching:
Cache $GOPATH/pkg/mod and $GOCACHE for faster tool execution.
