## What it does

The skill evaluates workload profiles before proposing architecture decisions. It maps project requirements against distinct patterns such as telemetry or product analytics. Using dedicated decision files in `rules/`, the assistant determines suitable approaches for streaming ingestion and schema partitioning.

Every recommendation receives an explicit provenance label: `official` for statements backed directly by documentation, `derived` for logical deductions, or `field` for situational heuristics. When giving `field` guidance, the skill must explicitly state that the advice is heuristic, link partially applicable documentation from `mappings/doc_links.yaml`, and explain operational tradeoffs. This prevents situational heuristics from passing as verified vendor standards.

Output follows a fixed structure. Responses include workload summaries, core decisions, and verification steps using SQL smoke tests or operational metrics. The skill builds directly on top of `clickhouse-best-practices`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add ClickHouse/agent-skills --skill clickhouse-architecture-advisor -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add ClickHouse/agent-skills --skill clickhouse-architecture-advisor -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/clickhouse-architecture-advisor/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add ClickHouse/agent-skills --skill clickhouse-architecture-advisor -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/clickhouse-architecture-advisor/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install ClickHouse/agent-skills clickhouse-architecture-advisor
```

2. **Manually: put the files in place**
- File: `.github/skills/clickhouse-architecture-advisor/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add ClickHouse/agent-skills --skill clickhouse-architecture-advisor -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/ClickHouse/agent-skills --path skills/clickhouse-architecture-advisor
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/clickhouse-architecture-advisor/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add ClickHouse/agent-skills --skill clickhouse-architecture-advisor -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/ClickHouse/agent-skills/tree/HEAD/skills/clickhouse-architecture-advisor/SKILL.md

## When to use it
- design streaming ingestion patterns for high-throughput event data
- plan time-series partitioning and retention rules in ClickHouse
- structure real-time preaggregation models for low-latency queries
- configure dimension lookups and join enrichment without operational bottlenecks

## Example prompts
- Design a ClickHouse ingestion and partitioning strategy for IoT telemetry data
- How should I structure real-time preaggregation for high-volume event logs?
- Recommend an architecture pattern for handling late-arriving upserts in ClickHouse

# ClickHouse Architecture Advisor

This skill adds workload-aware architecture decisioning on top of `clickhouse-best-practices`.

> **Official docs remain the source of truth.**
> This skill must always prefer official ClickHouse documentation when available.

## Required behavior

Before producing recommendations:

1. Identify the workload shape
   - observability
   - security / SIEM
   - product analytics
   - IoT / telemetry
   - market data / financial services
   - mixed OLAP with point-lookups
2. Read the relevant decision rule files in `rules/`
3. Use `mappings/doc_links.yaml` to attach official documentation
4. Classify every recommendation as:
   - `official`
   - `derived`
   - `field`
5. Never present field guidance as official guidance
6. If a recommendation is uncertain, say so explicitly

## Provenance rules

### `official`
Use this when the recommendation is directly backed by official docs.

### `derived`
Use this when the recommendation is not stated verbatim in docs but follows logically from documented ClickHouse behavior.

### `field`
Use this only for experience-based guidance that may be situational.
When using `field`, include:
- a disclaimer that the advice is heuristic
- a relevant official doc if one partially applies
- the reason the advice depends on workload context

## Read these rule files by scenario

### Real-time ingestion design
1. `rules/decision-ingestion-strategy.md`
2. `rules/decision-real-time-preaggregation.md`
3. Relevant best-practices insert rules

### Time-series and retention design
1. `rules/decision-partitioning-timeseries.md`
2. Relevant best-practices schema partition rules

### Enrichment and dimension lookups
1. `rules/decision-join-enrichment.md`
2. Relevant best-practices query join rules

### Mutable state / late-arriving events
1. `rules/decision-late-arriving-upserts.md`
2. Relevant best-practices mutation avoidance rules

## Output format
```
