  Show VisionSqueezer cumulative token & byte savings analytics. Zero MCP
  overhead — reads directly from local stats.db via CLI binary. Use when user
  says "vision-stats", "squeeze stats", "token savings", "how much saved",
  "vision-squeezer stats", "optimization history", or "/vision-stats".
allowed-tools: Bash

# vision-stats — VisionSqueezer Analytics Skill

Zero-overhead stats. Calls \`vision-squeezer stats\` directly — no MCP round-trip.

## Trigger

\`/vision-stats\` or any of: "vision stats", "squeeze stats", "show savings", "how much have I saved", "optimization stats"

## Action

Run this binary resolution chain, stop at first success:

\`\`\`bash
vision-squeezer stats 2>/dev/null \\
  || ~/.cargo/bin/vision-squeezer stats 2>/dev/null \\
  || "$(dirname "$(command -v vision-squeezer-mcp 2>/dev/null)")/vision-squeezer" stats 2>/dev/null \\
  || find "$HOME/.cargo/bin" "$HOME/Desktop" "$HOME/Projects" -maxdepth 6 -name "vision-squeezer" -not -path "*/deps/*" -not -path "*/debug/*" 2>/dev/null | head -1 | xargs -I{} {} stats 2>/dev/null \\
  || echo "vision-squeezer not found. Install: cargo install vision-squeezer"
\`\`\`

Print output verbatim. No wrapping, no commentary, no interpretation.

## Error handling

Binary not found → tell user to run \`cargo install vision-squeezer\` or \`eval "$(vision-squeezer setup-hook)"\` after install.

## Notes

- Stats persist in local stats.db on the user's machine
- MCP tool \`get_savings_stats\` does the same but costs ~150 tokens overhead — use this skill instead

  Check VisionSqueezer installation health and version status. Detects installed

  Use when user says "vision-doctor", "check vision-squeezer version", "update vision-squeezer",
  "is vision-squeezer up to date", "upgrade vision-squeezer", or "/vision-doctor".

# vision-doctor — VisionSqueezer Health Check Skill

Checks binary installation, current version, and latest available version.

## Trigger

\`/vision-doctor\` or any of: "vision doctor", "check vision-squeezer", "update vision-squeezer",
"is vision-squeezer up to date", "upgrade vision-squeezer", "vision-squeezer version"

## Action

Run the following shell script:

\`\`\`bash
BIN=$(command -v vision-squeezer 2>/dev/null)
if [ -z "$BIN" ] && [ -x "$HOME/.cargo/bin/vision-squeezer" ]; then
  BIN="$HOME/.cargo/bin/vision-squeezer"
fi
if [ -n "$BIN" ] && [ -x "$BIN" ]; then
  INSTALLED=$("$BIN" --version 2>/dev/null | grep -oE '[0-9]+\\.[0-9]+\\.[0-9]+' | head -1)
else
  INSTALLED=""
  BIN=""
fi
LATEST=$(npm view vision-squeezer version 2>/dev/null)
MCP_CMD=$(claude mcp list 2>/dev/null | grep vision-squeezer | head -1 || echo "")
echo "BIN=$BIN"
echo "INSTALLED=$INSTALLED"
echo "LATEST=$LATEST"
echo "MCP=$MCP_CMD"
\`\`\`

## Output format

Display as a markdown checklist:

\`\`\`
## VisionSqueezer Doctor

- [x/ ] Binary found: <path or "not found (using npx)">
- [x/ ] Installed version: <version or "n/a — npx always pulls latest">
- [x/ ] Latest version (npm): <version>
- [x/ ] MCP registered: <yes/no>
- [x/ ] Status: <see below>
\`\`\`

### Status logic

| Condition | Status |
|-----------|--------|
| \`INSTALLED\` == \`LATEST\` | ✅ Up to date |
| \`INSTALLED\` != \`LATEST\`, both non-empty | ⚠️ Update available — run \`/vision-upgrade\` |
| \`BIN\` empty, \`MCP\` contains "npx" | ✅ Using npx — always latest, no action needed |
| \`BIN\` empty, no MCP | ❌ Not installed |

### If update available:

\`\`\`
Update available: v<INSTALLED> → v<LATEST>
Run /vision-upgrade to update.
\`\`\`

### If not installed:

\`\`\`
## VisionSqueezer not found

Install via Claude Code (one-liner):
  claude mcp add vision-squeezer -- npx -y vision-squeezer
\`\`\`

## Notes

- \`npx -y vision-squeezer\` users are always on latest — show this as ✅, not an error
- cargo install users must run \`/vision-upgrade\` or \`cargo install vision-squeezer\` to upgrade

    'vision-upgrade': `---
name: vision-upgrade
description: >
  Upgrade VisionSqueezer to the latest version. Detects install method (cargo, npm global, npx)
  and runs the correct update command. Use when user says "vision-upgrade", "upgrade vision-squeezer",
  "update vision-squeezer", or "/vision-upgrade".
allowed-tools: Bash
---

# vision-upgrade — VisionSqueezer Upgrade Skill

Detects install method and upgrades to latest.

## Trigger

\`/vision-upgrade\` or any of: "vision upgrade", "upgrade vision-squeezer", "update vision-squeezer", "install latest vision-squeezer"

## Action

Run the following detection script first:

\`\`\`bash
BIN=$(command -v vision-squeezer 2>/dev/null)
[ -z "$BIN" ] && [ -x "$HOME/.cargo/bin/vision-squeezer" ] && BIN="$HOME/.cargo/bin/vision-squeezer"
INSTALLED=""
[ -n "$BIN" ] && [ -x "$BIN" ] && INSTALLED=$("$BIN" --version 2>/dev/null | grep -oE '[0-9]+\\.[0-9]+\\.[0-9]+' | head -1)
LATEST=$(npm view vision-squeezer version 2>/dev/null)
NPM_GLOBAL=$(npm list -g vision-squeezer --depth=0 2>/dev/null | grep vision-squeezer | head -1)
echo "BIN=$BIN"
echo "INSTALLED=$INSTALLED"
echo "LATEST=$LATEST"
echo "NPM_GLOBAL=$NPM_GLOBAL"
\`\`\`

### Then run the appropriate upgrade command:

**If \`NPM_GLOBAL\` non-empty** (npm global install):
\`\`\`bash
npm install -g vision-squeezer
\`\`\`

**If \`BIN\` contains \`.cargo\`** (cargo install):
\`\`\`bash
cargo install vision-squeezer
\`\`\`

**If \`BIN\` empty** (npx user):
No action needed — npx always pulls latest. Confirm to user.

### After upgrade, verify:
\`\`\`bash
vision-squeezer --version 2>/dev/null || ~/.cargo/bin/vision-squeezer --version 2>/dev/null
\`\`\`

## Output format

\`\`\`
## VisionSqueezer Upgrade

- [ ] Detected install method: <cargo / npm global / npx>
- [ ] Version before: v<INSTALLED or "n/a">
- [ ] Running upgrade...
- [ ] Version after: v<NEW_VERSION>
- [ ] Status: ✅ Updated to v<LATEST> / ✅ Already on latest (npx)
\`\`\`

## Notes

- npx users: always on latest, no upgrade needed — tell them explicitly
- If cargo install fails (no Rust): suggest switching to npx with \`claude mcp add vision-squeezer -- npx -y vision-squeezer\`
