llamafarm: Skill for Claude Code

.claude/skills/go-skills/SKILL.md

go-skills is a skill for Claude Code from llama-farm/llamafarm. It costs 25 tokens per session (729 once invoked), scanned A, original, Apache-2.0.

A set of Go programming guidelines for the LlamaFarm command-line application, covering errors, concurrency, interfaces, and tests.

In plain words
What is it for?
Use it when changing Cobra commands, terminal interfaces, utilities, internal packages, concurrent code, or Go tests.
Why use it?
It helps agents write Go code that matches the project's structure and handles failures, shared data, and test cases consistently.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

This is llama-farm/llamafarm's own configuration. It tells Claude Code how to work on llamafarm itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything llamafarm configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

go-skills scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Go Skills for LlamaFarm CLI

Shared Go best practices for LlamaFarm CLI development. These guidelines ensure idiomatic, maintainable, and secure Go code.

Tech Stack

  • Go 1.24+
  • Cobra (CLI framework)
  • Bubbletea (TUI framework)
  • Lipgloss (terminal styling)

Directory Structure

cli/
  cmd/           # Command implementations
    config/      # Configuration types and loading
    orchestrator/ # Service management
    utils/       # Shared utilities
    version/     # Version and upgrade handling
  internal/      # Internal packages
    tui/         # TUI components
    buildinfo/   # Build information

Quick Reference

Error Handling

  • Always wrap errors with context: fmt.Errorf("operation failed: %w", err)
  • Use sentinel errors for expected conditions: var ErrNotFound = errors.New("not found")
  • Check errors immediately after function calls

Concurrency

  • Use sync.Mutex for shared state protection
  • Use sync.RWMutex when reads dominate writes
  • Use channels for goroutine communication
  • Always use defer for mutex unlocks

Testing

  • Use table-driven tests for comprehensive coverage
  • Use interfaces for mockability
  • Test file names: *_test.go in same package

Security

  • Never log credentials or tokens
  • Redact sensitive headers in debug logs
  • Validate all external input
  • Use context.Context for cancellation

Checklist Files

File Description
patterns.md Idiomatic Go patterns
concurrency.md Goroutines, channels, sync
error-handling.md Error wrapping, sentinels
testing.md Table-driven tests, mocks
security.md Input validation, secure coding

Go Proverbs to Remember

  1. "Don't communicate by sharing memory; share memory by communicating"
  2. "Errors are values"
  3. "A little copying is better than a little dependency"
  4. "Clear is better than clever"
  5. "Design the architecture, name the components, document the details"

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

go-skills is a skill published in the GitHub repository llama-farm/llamafarm (838 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 25 tokens to every session and 729 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
