# Send Pincer to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path

- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.

## Documentation

### pincer 🛡️

Security-first wrapper for clawhub install. Scans skills for malware, prompt injection, and suspicious patterns before installation.

### Why?

Agent skills are powerful — they're basically executable documentation. The ClawHub ecosystem has already seen malware campaigns distributing infostealers via innocent-looking skills. pincer adds a security layer before you install anything.

### Install

# From ClawHub
clawhub install pincer

# Or manually
chmod +x ./scripts/pincer.sh
ln -sf "$(pwd)/scripts/pincer.sh" ~/.local/bin/pincer

Dependencies:

clawhub — for fetching skills
uvx — for mcp-scan (brew install uv)
jq — for JSON parsing

### Safe Install

# Instead of: clawhub install some-skill
pincer install some-skill

# With specific version
pincer install some-skill@1.2.0

### Scan Without Installing

# Scan a ClawHub skill
pincer scan some-skill

# Scan a local directory
pincer scan ./path/to/skill

# JSON output for automation
pincer scan some-skill --json

### Audit Installed Skills

# Quick-scan all installed skills
pincer audit

# JSON output
pincer audit --json

### Manage Trust

# Add trusted publisher (auto-approve clean skills)
pincer trust add steipete

# Remove from trusted
pincer trust remove old-publisher

# Block a publisher or skill
pincer trust block suspicious-dev
pincer trust block malware-skill

# Unblock
pincer trust unblock redeemed-dev

# List all trust settings
pincer trust list

### View History

# See what you've installed

# JSON output

### Configuration

# Show current config

# Edit in $EDITOR
