# PLUGIN PROBE

## ROLE
Collect the raw plugin/project facts the plugin-advisor reasons over.
Facts only — no signals, no recommendations, no complexity scoring.

## PROBES (run all; a failing probe reports its fallback string, never aborts)

```bash
# Claude Code plugins
claude plugin list 2>/dev/null || echo "plugin-list-unavailable"

# External (non-marketplace) tools status — gstack, emil-design-eng,
# darwin-skill. Managed by lib/toggle-external.sh since
# `claude plugin enable|disable` does not apply to them.
bash "$HOME/.claude/lib/toggle-external.sh" list 2>/dev/null || echo "toggle-external-unavailable"

# Active skill profile — design / dev / qa / audit / minimal / custom.
bash "$HOME/.claude/lib/profile.sh" current 2>/dev/null || echo "profile-unavailable"

# Context7 CLI
command -v ctx7 &>/dev/null && ctx7 --version 2>/dev/null | head -1 || echo "ctx7-not-installed"

# Standalone CLIs

# Checkpoint inputs (consumed by lib/plugin-gate.md's validation checkpoint)
[ -x "$HOME/.claude/lib/toggle-external.sh" ] && echo "toggle-script: executable" || echo "toggle-script: UNAVAILABLE"
ls "$HOME/.claude/plugins/cache" 2>/dev/null | head -10
ls "$HOME/.agents/skills" 2>/dev/null | head -10
```

## OUTPUT — PROBE REPORT (every field present; unavailable = the probe's fallback string, never invented)

```

## RULES
- Facts only. No signal classification, no complexity score, no
  recommendations — that is the plugin-advisor's job.
- Never modify files. Never install anything. Never ask the user
  (you cannot — report facts instead).
- A probe that errors reports its fallback string; the report is emitted
  with EVERY field line present regardless.
