refactor-clean

refactor-clean is a command for Claude Code from gopherguides/gopher-ai. It costs 14 tokens per session (1,852 once invoked), scanned A, original, MIT.

A command for finding unused Go code, abandoned test files, overly complicated functions, and unused imports across a project or selected package path.

In plain words
What is it for?
Use it to inspect a Go project, review dead-code and complexity findings, optionally run a report-only check, then apply approved cleanup and verify the build and tests.
Why use it?
It helps reveal code that can be removed or simplified, reducing maintenance work and making the project easier to understand. It reports findings first and asks for confirmation before applying fixes.

Command for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: mentions subagents; names the AskUserQuestion tool; mentions Claude Code.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

refactor-clean 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.

If $ARGUMENTS is empty or not provided:

Find and clean dead code across the entire Go project.

Usage: /refactor-clean [path] [options]

Examples:

  • /refactor-clean - Analyze entire project for dead code
  • /refactor-clean ./pkg/... - Analyze specific package tree
  • /refactor-clean --dry-run - Report findings without applying fixes
  • /refactor-clean ./internal/auth --dry-run - Report-only for a specific package

Analysis categories: unused exported functions/types, orphaned test files, overly complex functions, unused imports.

Workflow: detect tools → parallel-dispatch 4 analysis subagents → present findings report → apply fixes only after user confirmation → verify build + tests.

Set default: TARGET_PATH="./..." and proceed.


If $ARGUMENTS is provided:

Parse $ARGUMENTS:

  • Argument starting with ./ or a package pattern → TARGET_PATH
  • --dry-run → set DRY_RUN=true, default TARGET_PATH="./..."
  • Both: extract path to TARGET_PATH, set DRY_RUN=true

Loop Initialization

!if [ ! -x "${CLAUDE_PLUGIN_ROOT}/scripts/setup-loop.sh" ]; then echo "ERROR: Plugin cache stale. Run /gopher-ai-refresh (or refresh-plugins.sh) and restart Claude Code."; exit 1; else "${CLAUDE_PLUGIN_ROOT}/scripts/setup-loop.sh" "refactor-clean" "COMPLETE"; fi

Step 1: Verify Go Project

if [ ! -f go.mod ]; then
  echo "ERROR: No go.mod found. This command must be run from a Go project root."
  exit 1
fi
head -5 go.mod

Capture the module path from go.mod for import analysis.

Step 2: Detect Available Analysis Tools

echo "=== Tool Detection ==="
which staticcheck 2>/dev/null && staticcheck --version || echo "staticcheck: NOT FOUND"
which deadcode 2>/dev/null || echo "deadcode: NOT FOUND (golang.org/x/tools/cmd/deadcode)"

which gocognit 2>/dev/null || echo "gocognit: NOT FOUND"

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.
