## Install

```sh

## About

## What I do

Create and validate OpenCode skills following the Anthropic Agent Skills spec.
Skills that violate these rules fail silently: not discovered, not matched, or
waste tokens.

## Directory structure

```
.claude/skills/{skill-name}/
└── SKILL.md
```

One directory per skill. Directory name must match `name` in frontmatter.
Only one file: `SKILL.md` (uppercase). No subdirectories.

## SKILL.md format

```markdown
---
name: {skill-name}
description: >-
  {capability summary}. {use cases}. {proactive triggers}.
  Examples:
  - user: "{english phrase}" -> {action}
  - user: "{spanish phrase}" -> {action}
  Never use this for {anti-pattern}.
---

## Environment
All commands run via `ssh web`.

## Instructions
{Step-by-step actionable content}

## Verification
{How to verify correctness}
```

## Frontmatter rules

### name (REQUIRED)
- 1-64 chars, lowercase alphanumeric + single hyphens
- Must match directory name exactly
- Valid: `module-scaffold`, `quality-checks` | Invalid: `drupal_module`, `MySkill`

### description (REQUIRED, 1-1024 chars)
This is the ONLY text the LLM sees during skill selection. Structure:
1. **Capability**: What it does (1 sentence)
2. **Use cases**: When to invoke (1-2 sentences)
3. **Examples**: 2-4 with `user: "X" -> Y` format
4. **Anti-pattern**: "Never use for X"
5. Must include Spanish AND English triggers

## Progressive disclosure

```
Startup: Only name + description loaded (XML summary)
User message -> LLM matches description -> skill tool called -> full body loaded
```

If description doesn't match user intent, body NEVER loads.

## Validation checklist

- [ ] Directory name = `name` field
- [ ] Name: lowercase, hyphens only, 1-64 chars
- [ ] Description: 1-1024 chars
- [ ] Description has: capability, use cases, 2+ examples, anti-pattern
- [ ] Description has Spanish triggers
- [ ] YAML frontmatter valid
- [ ] Body has actionable instructions (not prose)
- [ ] Commands use `ssh web`
- [ ] No duplication with other skills or rules/
- [ ] No conflicts with CLAUDE.md policies
- [ ] File named exactly `SKILL.md`
- [ ] Body under 200 lines

## Audit mode

When reviewing existing skills:

```bash
find .claude/skills -name "SKILL.md" | while read f; do
  dir=$(basename $(dirname "$f"))
  name=$(grep "^name:" "$f" | head -1 | awk '{print $2}')
  lines=$(wc -l ` |
| No anti-pattern | Add "Never use for X" |
| Bare commands | Prefix `ssh web` |
| Body 200+ lines | Split into skill + rule reference |
| English-only triggers | Add Spanish phrases |
| Duplicates other skill | Merge or add anti-pattern boundary |
