## About

# Skill MCP - Master Usage Guide

## What Is the Skill MCP?

The Skill MCP server is a **self-hosted agent skills registry** accessible to any
MCP-compatible AI agent or tool. It stores curated, expert-authored instruction sets
("skills") and delivers them on demand through a structured 3-tier disclosure model.

Each skill contains:

| Tier | Content | Tools |
|------|---------|-------|
| 1 | Frontmatter - name, description, tags, score | `skills_find_relevant` |
| 2 | Instructions, system prompt addition | `skills_get_body`, `skills_get_options` |
| 3 | Reference docs, executable scripts, asset templates | `skills_get_reference`, `skills_run_script`, `skills_get_asset` |

---

## The Canonical 3-Step Workflow

Follow this sequence for every task where a skill might apply.

### Step 1 - Discover (`skills_find_relevant`)

```
skills_find_relevant(query="", top_k=5)
```

**Interpret scores:**
- `score > 0.6` → strong match - proceed to Step 2
- `score 0.4–0.6` → possible match - read description to decide
- `score ")
```

The response contains:

```json
{
  "skill_id": "test-writer",
  "instructions": "## Testing Workflow\n1. Identify the function under test ...",
  "system_prompt_addition": "You are a senior test engineer ...",
  "tier3_manifest": {
    "references": ["TESTING-GUIDE.md", "COVERAGE-POLICY.md"],
    "scripts":    ["coverage_check.py"],
    "assets":     ["test-template.py"]
  }
}
```

**After loading:**
1. Read and apply `instructions` - this is the authoritative guidance
2. If `system_prompt_addition` is non-empty, incorporate it into your context
3. Check `tier3_manifest` - only proceed to Step 3 if instructions reference specific files

**Optional: load config** (`skills_get_options`)
```
skills_get_options(skill_id="")
```
Only needed when customising skill behaviour or checking constraints/dependencies.

---

### Step 3 - Supplement (only when needed)

**3a - Reference documents:**
```
# First: get the manifest
skills_get_reference(skill_id="test-writer", filename="list")
# Then: fetch the specific file the instructions mentioned
skills_get_reference(skill_id="test-writer", filename="TESTING-GUIDE.md")
```

**3b - Execute a helper script:**
```
# First: see available scripts
skills_run_script(skill_id="test-writer", filename="list")
# Then: run with optional inputs
skills_run_script(skill_id="test-writer", filename="coverage_check.py",
                  input_data={"TARGET_DIR": "./src", "MIN_COVERAGE": "80"})
# Returns: exit_code, stdout, stderr - source is never exposed
```

**3c - Fetch a template or asset:**
```
# First: get the manifest
skills_get_asset(skill_id="test-writer", filename="list")
# Then: fetch the template
skills_get_asset(skill_id="test-writer", filename="test-template.py")
# Use as a starting template - adapt it to the specific task
```

> **Rule:** Only load Tier 3 resources that the Tier 2 instructions explicitly
> reference. Do not load them speculatively - it wastes context and latency.

## Complete Example

```
# 1. Discover
results = skills_find_relevant(
    query="write integration tests for a Python REST API using pytest"
)
# → test-writer: 0.84  ← strong match

# 2. Load instructions
body = skills_get_body(skill_id="test-writer")
# → instructions: "## Testing Workflow ..."
# → tier3_manifest.references: ["TESTING-GUIDE.md"]
# → tier3_manifest.assets: ["test-template.py"]

# 3. The instructions say "follow TESTING-GUIDE.md for project conventions"
guide = skills_get_reference(skill_id="test-writer", filename="TESTING-GUIDE.md")

# 4. The instructions say "use test-template.py as your file scaffold"
template = skills_get_asset(skill_id="test-writer", filename="test-template.py")

# 5. Apply instructions using the guide and template
```

## Decision Rules

| Situation | Action |
|-----------|--------|
| Starting any non-trivial task | Always call `skills_find_relevant` first |
| All scores  0.4 | Call `skills_get_body` to load instructions |
| Instructions are complete | Apply them - stop, do not load Tier 3 |
| Instructions mention a file | Load that specific file via Tier 3 |
| User asks to customise skill | Call `skills_get_options` |
| Task is trivial (.workers.dev/sse`
