## What it does

\`dt-sec-semantic-mapping` maps vendor API payloads to `security.events` fields and reviews existing mappings. It supports three workflows: drafting a new mapping, checking one against local samples and the Semantic Dictionary, or validating it with live tenant data.

The checks cover event-type coverage, required fields, namespaces, value and type rules, scan references, and duplicated vendor namespaces. The skill uses files such as `references/semantic-reference.md`, `references/mapping-workflow.md`, and `references/validation-policy-and-reporting.md` to produce mapping tables, discrepancy reports, and improvement suggestions.

Runtime validation requires live tenant access. Its B2 workflow also requires loading the supporting AppSec events skill before the query pack runs, so that prerequisite blocks runtime checks when it is missing.

## Requirements
- Works with: Dynatrace

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-sec-semantic-mapping -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/dt-sec-semantic-mapping/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/dt-sec-semantic-mapping/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-sec-semantic-mapping -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/dt-sec-semantic-mapping/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-sec-semantic-mapping -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/dt-sec-semantic-mapping/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Dynatrace/dynatrace-for-ai dt-sec-semantic-mapping
```

2. **Manually: put the files in place**
- File: `.github/skills/dt-sec-semantic-mapping/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-sec-semantic-mapping -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Dynatrace/dynatrace-for-ai --path skills/dt-sec-semantic-mapping
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/dt-sec-semantic-mapping/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Dynatrace/dynatrace-for-ai --skill dt-sec-semantic-mapping -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Dynatrace/dynatrace-for-ai/tree/HEAD/skills/dt-sec-semantic-mapping/SKILL.md

## When to use it
- map vendor API payloads to `security.events` fields
- check required fields in a new integration mapping
- compare a mapping with the Semantic Dictionary
- detect namespace and value-type discrepancies
- validate mappings against live tenant data

## Example prompts
- Suggest a mapping from this vendor API payload to `security.events`, and list the evidence still needed.
- Validate this mapping against the local samples and Semantic Dictionary; return a discrepancy table.
- Run runtime validation for this mapping against the live tenant and prepare the Validation Summary.

# dt-sec-semantic-mapping

Build and validate semantic-dictionary-aligned mappings for new security integrations.

## Purpose

Use this skill when a user wants to:

- **Suggest** a mapping from vendor API output to Dynatrace `security.events` fields (Workflow A).
- **Validate** an existing mapping for completeness and quality against:
  - Local baseline samples and semantic dictionary (Workflow B1 — static, offline validation), or
  - Live tenant data via live tenant access (Workflow B2 — runtime validation)
- Highlight discrepancies vs. the Semantic Dictionary and local references.
- Get actionable mapping improvements.

## Semantic Dictionary

The Semantic Dictionary (SD) defines the canonical field set for `security.events`. See `references/semantic-reference.md` for the canonical reference: local-vs-live sources, queryable Grail tables, when-to-query decision matrix, and the authority rule (live SD wins on disagreement).

## Required Inputs

Always run the intake checklist in `references/intake-and-constraints.md` before generating or validating a mapping. If inputs are incomplete, continue with a partial draft but explicitly list missing evidence and confidence limits.

## Baseline Sources (self-contained)

All baseline material lives inside this skill:

- `samples/` — real integration payloads covering all finding types and providers. Consulted as a fallback when primary references (SD, data-model-notes, known-discrepancies, validation-rules, object-type-expectations) leave a specific question unresolved — not as a routine step on every workflow run.
- `references/semantic-reference.md` — SD reference, field taxonomy, event types, provider taxonomy, and entity scoping
- `references/validation-policy-and-reporting.md` — validation rules, acceptable discrepancies, and report templates
- `references/intake-and-constraints.md` — intake checklist, output contract, `object.type` expectations, and OpenPipeline constraints
