## What it does

This audit gate assesses whether a project repository is truly distribution-ready. It begins by inspecting README structure for clear install steps, quick start code blocks, and version labels. Next, it looks for standard manifests such as `plugin.json` or `package.json` to confirm zero-config onboarding requirements.

Project velocity is inspected via `git log`, changelog updates, and release tags. After that, the gate scans for internal `SKILL.md` paths and compares discovered skill names against hub plugins listed under `FH_DIR`. If `FH_DIR` remains unset, the hub comparison reports a visible skipped status instead of masking missing coverage.

Without `public-surface-audit` installed in your environment, the final safety check falls back to simple regex screening for leftover placeholders and token assignments.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill marketplace-gate -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill marketplace-gate -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill marketplace-gate -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install chrono-meta/forge-harness marketplace-gate
```

2. **Manually: put the files in place**
- File: `.github/skills/marketplace-gate/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill marketplace-gate -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/chrono-meta/forge-harness --path plugins/fh-meta/skills/marketplace-gate
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add chrono-meta/forge-harness --skill marketplace-gate -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/chrono-meta/forge-harness/tree/HEAD/plugins/fh-meta/skills/marketplace-gate/SKILL.md

## When to use it
- evaluate documentation readiness before distributing a plugin
- spot stale repositories lacking recent commits or tags
- detect naming collisions against existing hub skills
- catch hardcoded credentials and internal domains in configs

## Example prompts
- /marketplace-gate
- /marketplace-gate --target ./subprojects/my-tool
- Review this repo before open-source release

# marketplace-gate — Marketplace Listing Suitability Gate

Evaluates a repository against 5 listing criteria — README completeness, zero-config readiness, maintenance signals, duplication, and public safety — and outputs a listing suitability verdict.

> While `asset-placement-gate` answers "is this asset suitable for FH?",
> `marketplace-gate` answers "is this repo ready to be listed in a marketplace?"

## Triggers

- `/marketplace-gate`
- `/marketplace-gate --target <repo path>`
- "Can I list this in the marketplace?", "Pre-listing repo check", "Verify before publishing", "Is this ready for marketplace listing?"
- "Can other teams use this repo?", "Is there a checklist before external distribution?", "Check if this is ready to be public"
- "Review for open-source release", "Verify before sharing outside the team"

---

## Step 0. Confirm Target Path

Use the path specified by `--target <path>` if provided. Otherwise use current cwd.

```bash
REPO_PATH="${ARGUMENTS#--target }"
REPO_PATH="${REPO_PATH:-$(pwd)}"
echo "Target: $REPO_PATH"
ls "$REPO_PATH" 2>/dev/null | head -20 || echo "Path not found — please verify the path"
```

Stop immediately if path is not found.

---

## Step 1. 5-Point Check

### Check 1 — README Completeness

```bash
README=$(ls "$REPO_PATH"/README* 2>/dev/null | head -1)
[ -z "$README" ] && echo "FAIL: No README found" && exit
# Installation command exists
grep -i "install\|clone\|setup" "$README" | head -3
# Code block (usage example) exists
grep -c '```' "$README" 2>/dev/null
```

| Criterion | Check |
|---|---|
| README file exists | ls |
| Purpose in 1 sentence (first 50 lines) | presence check |
| Installation path documented | install·clone·setup keywords |
| At least 1 usage example | code block presence |
| Version notation | version·v[0-9] pattern |

Result: **PASS** (5/5) / **PARTIAL** (3-4/5) / **FAIL** (≤2/5)

### Check 2 — Immediate Usability (zero-config)

```bash
# plugin manifest exists
ls "$REPO_PATH"/.claude-plugin/plugin.json "$REPO_PATH"/package.json 2>/dev/null
# single-line install command (from README)
grep -i "claude plugin install\|npm install\|pip install\|brew install" "$README" 2>/dev/null | head -3
# prerequisites documented
grep -i "prerequisite\|requirement\|env\|api.key" "$README" -A 2 | head -6
```

| Criterion | Check |
|---|---|
| Single-line install command in README | grep |
| Prerequisites documented (API key, env var, etc.) | grep |
| Plugin manifest exists | ls |

Result: **PASS** / **PARTIAL** / **FAIL**

### Check 3 — Maintenance Signals

```bash
````
