Golang How To

Configure mode — force-trigger Go skills in a project

This workflow writes two independent things to the project's agent-config file(s) (CLAUDE.md, AGENTS.md, or equivalent):

1. An always-load directive for golang-how-to itself — a single sentence, unconditional, no user confirmation needed.

2. An optional ## Required Go skills block that force-triggers a specific, user-confirmed set of secondary skills.

When to use

• Any new Go project should get the always-load directive (see below) — this is the common case.

• The project additionally has a hard requirement on specific skills (e.g., golang-security must always apply, not just when the user mentions "security").

• The team has agreed on a fixed set of Go standards to enforce on every AI interaction.

• A company skill overrides a community default (⚙️ skills) and must always win.

Always-load directive

Every Go project should carry a one-line directive telling the coding agent to load the samber/cc-skills-golang@golang-how-to orchestrator skill before starting Go work, so it in turn routes to whichever other Go skills the task actually needs. Unlike the ## Required Go skills block below, this directive needs no user confirmation: it costs one skill description (~100 tokens) and is never wrong, since golang-how-to only routes to other skills — it does not impose project-specific choices.

Template

Before any Go coding, review, debugging, troubleshooting, or setup task, load the `samber/cc-skills-golang@golang-how-to` skill first — it routes to whichever other Go skills the task needs.

When it gets written

• At project creation — the samber/cc-skills-golang@golang-project-layout skill writes this directive automatically as part of its Initialization Checklist, without asking the user.

• On demand — running /golang-how-to configure writes it too (if missing), in addition to any ## Required Go skills block confirmed in Step 3 below.

Insertion point

• If a ## Required Go skills block already exists or is being created in the same pass, insert the directive as its own line directly above that heading, separated by a blank line.

• Otherwise, append it under a ## Go development heading (create the heading if the file has no such section).

Idempotency

Grep for the exact sentence before writing:

grep -n 'load the `samber/cc-skills-golang@golang-how-to` skill first' CLAUDE.md

Skip writing if already present.

Step 1 — Detect the project config file(s)

Every harness reads its own agent-config file or directory. None is more "primary" than another — detect and write to whichever exist, and write to all of them if more than one does:

Check which of these exist at the project root. If multiple exist, write to all of them — different harnesses read different files, and a project may support several. If none exist, ask the user which one(s) to create.

Step 2 — Idempotency check

For the markdown files (CLAUDE.md, AGENTS.md, GEMINI.md, .github/copilot-instructions.md), grep each one for the always-load directive and an existing ## Required Go skills block before writing:

grep -n 'load the `samber/cc-skills-golang@golang-how-to` skill first' CLAUDE.md
grep -n "## Required Go skills" CLAUDE.md

For Cursor, check whether .cursor/rules/golang-skills.mdc already exists instead — its presence itself is the idempotency signal, since it's a dedicated file rather than a shared section inside a larger document.

Write the always-load directive if it's missing, regardless of what Step 3 decides. If a ## Required Go skills block (or, for Cursor, the rule file) already exists, read it and confirm with the user whether to update it in place (replace the existing list) or skip.

Step 3 — Confirm the skill set with the user

Confirm which skills to always load — one question, one round of confirmation, not a running back-and-forth. Present the ⭐️ recommended skills as the default selection. Remind the user of the token budget (each always-loaded skill adds its description tokens to every session — the 11 recommended skills add ~1,100 tokens at startup).

Recommended ⭐️ set for most projects:

golang-code-style
golang-data-structures
golang-design-patterns
golang-documentation
golang-error-handling
golang-modernize
golang-naming
golang-safety
golang-security
golang-testing
golang-troubleshooting

Additional skills to suggest based on codebase context:

• Database layer detected (sql, gorm, sqlc) → suggest golang-database

• CI config detected (.github/workflows/) → suggest golang-continuous-integration

• Cobra imports detected → suggest golang-spf13-cobra

• Viper imports detected → suggest golang-spf13-viper

• samber/lo imports detected → suggest golang-samber-lo

• Any other library-specific import → suggest the matching library skill

Step 4 — Write the block

Markdown targets (CLAUDE.md, AGENTS.md, GEMINI.md, copilot-instructions.md)

Template:

Before any Go coding, review, debugging, troubleshooting, or setup task, load the `samber/cc-skills-golang@golang-how-to` skill first — it routes to whichever other Go skills the task needs.

## Required Go skills

The following Go skills from `samber/cc-skills-golang` MUST always be applied when working on this project. Load them at the start of every Go-related task, regardless of whether the user explicitly mentions them.

- `samber/cc-skills-golang@golang-error-handling`
- `samber/cc-skills-golang@golang-security`
- `samber/cc-skills-golang@golang-testing`

Replace the skill list with the confirmed set from Step 3. Use the fully-qualified samber/cc-skills-golang@<name> identifier for each skill. If Step 2 found the always-load directive already present elsewhere in the file, don't duplicate it — write only the ## Required Go skills block.

Insertion point:

• If the file is empty: write the block at the top.

• If the file has existing content: append after the last section, separated by a blank line.

• If a ## Required Go skills block already exists: replace only the bullet list inside it, preserving surrounding content.

Edit the file directly, rather than shelling out to a script — that keeps the change reviewable as a normal diff. Perform an idempotency check after writing: re-read the file and verify the block appears exactly once.

Cursor target (.cursor/rules/*.mdc)

.cursor/rules is a directory, not a file — each rule lives in its own .mdc file with YAML frontmatter (description, globs, alwaysApply). Do not try to append to it as if it were a single markdown document; the append-and-replace logic above does not apply here.

Create .cursor/rules/golang-skills.mdc (create the .cursor/rules/ directory first if it doesn't exist) using cursor-go-skills.mdc as the starting template, with alwaysApply: true so it always loads — matching the unconditional behavior of the markdown targets' always-load directive. Replace the placeholder ## Required Go skills list with the confirmed set from Step 3, same as the markdown targets. If the file already exists, replace only the bullet list, preserving its frontmatter and surrounding content.

Step 5 — Confirm to the user

After writing, summarize:

• Which file(s) or rule(s) were updated

• Whether the always-load directive for golang-how-to was added or was already present

• Which skills were added to the always-load list

• Approximate startup token cost (number of skills × ~100 tokens per description)

• Note: skills marked ⚙️ (overridable) will be superseded if a company skill explicitly declares the override in its body

Notes on company overrides (⚙️ skills)

Skills marked ⚙️ in the README support company overrides. If the project has a company skill that supersedes a community default (e.g., acme/cc-skills@golang-error-handling-acme supersedes samber/cc-skills-golang@golang-error-handling), use the company skill FQN in the block instead — do NOT list both.

To declare an override in a company skill body, add near the top:

> This skill supersedes `samber/cc-skills-golang@golang-error-handling` for [Company] projects.

Overridable skills: golang-code-style, golang-concurrency, golang-context, golang-database, golang-dependency-injection, golang-design-patterns, golang-documentation, golang-error-handling, golang-naming, golang-observability, golang-structs-interfaces, golang-testing.
