## What it does

This skill cleans up and tests Go CLIs generated by Printing Press. It runs diagnostics including `dogfood` and `verify`, alongside static analysis with `go vet` and `gosec`. The agent fixes detected failures directly, pruning dead code and updating `README` documentation. At the end, it reports a before-and-after comparison and offers to publish.

Execution takes place inside a forked context (`context: fork`). This isolates diagnostic iterations and noisy build logs from your main session. The caller receives only a concise summary. You can run the command directly on projects stored under `$PRESS_LIBRARY/`. It targets scenarios where the verify pass rate drops below 80% or shipcheck flags `ship-with-gaps`.

Without Go and a `cli-printing-press` binary at version `4.0.0` or newer, setup halts immediately. Disk space is checked before execution. If available space falls below 524288 KB, the script fails right away. Go build caches and module downloads consume significant disk room.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add mvanhorn/cli-printing-press --skill printing-press-polish -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/printing-press-polish/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/printing-press-polish/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add mvanhorn/cli-printing-press --skill printing-press-polish -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/printing-press-polish/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mvanhorn/cli-printing-press --skill printing-press-polish -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/printing-press-polish/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mvanhorn/cli-printing-press printing-press-polish
```

2. **Manually: put the files in place**
- File: `.github/skills/printing-press-polish/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mvanhorn/cli-printing-press --skill printing-press-polish -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mvanhorn/cli-printing-press --path skills/printing-press-polish
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/printing-press-polish/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mvanhorn/cli-printing-press --skill printing-press-polish -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mvanhorn/cli-printing-press/tree/HEAD/skills/printing-press-polish/SKILL.md

## When to use it
- fix verification failures and static analysis warnings in generated CLIs
- remove dead code from compiled Go projects
- update `README` docs and MCP tool definitions
- evaluate CLI readiness against `gosec` and `scorecard` gates

## Example prompts
- /printing-press-polish redfin
- Fix verify issues and make redfin-pp-cli publish-ready
- Clean up the CLI in "$PRESS_LIBRARY/redfin"

# /printing-press-polish

Polish a generated CLI so it passes verification and is ready to publish.

The retro improves the Printing Press. Polish improves the generated CLI. This skill runs in a forked context (`context: fork`) so its diagnostic and fix loop doesn't pollute the caller — the diagnostic spam, fix iterations, and re-diagnose noise stay scoped to the polish session, and the caller receives a clean summary.

```bash
/printing-press-polish redfin
/printing-press-polish redfin-pp-cli
/printing-press-polish "$PRESS_LIBRARY/redfin"
```

## When to run

After any `/printing-press` generation, especially when:
- The shipcheck verdict is `ship-with-gaps`
- The verify pass rate is below 80%
- The scorecard is below 85
- You want the CLI publish-ready in one pass

Can also be run standalone on any CLI in `$PRESS_LIBRARY/`.

## Setup

```bash
# min-binary-version: 4.0.0

PRESS_HOME="${PRINTING_PRESS_HOME:-$HOME/printing-press}"
PRESS_LIBRARY="$PRESS_HOME/library"

_pp_check_disk_space() {
  _pp_disk_warn_kb="${PRINTING_PRESS_DISK_WARN_KB:-3145728}"
  _pp_disk_fail_kb="${PRINTING_PRESS_DISK_FAIL_KB:-524288}"
  case "$_pp_disk_warn_kb$_pp_disk_fail_kb" in
    ""|*[!0-9]*) return 0 ;;
  esac

  _pp_disk_path="$PRESS_HOME"
  while [ ! -e "$_pp_disk_path" ] && [ "$_pp_disk_path" != "/" ]; do
    _pp_disk_path="$(dirname "$_pp_disk_path")"
  done

  _pp_disk_avail_kb="$(df -Pk "$_pp_disk_path" 2>/dev/null | awk 'BEGIN {
    if ((getline header) <= 0 || (getline record) <= 0) exit
    field_count = split(record, fields)
    if (field_count >= 4) print fields[4]
  }')"
  case "$_pp_disk_avail_kb" in
    ""|*[!0-9]*) return 0 ;;
  esac

  if [ "$_pp_disk_avail_kb" -lt "$_pp_disk_fail_kb" ]; then
    echo ""
    echo "[setup-error] Critically low disk space on the Printing Press workspace volume."
    echo "PRESS_DISK_PATH=$_pp_disk_path"
    echo "PRESS_DISK_AVAIL_KB=$_pp_disk_avail_kb"
