## What it does

discover-analytics-patterns searches the repository for the code that sends analytics events. It checks SDK calls, custom wrappers, hooks, imports, and function signatures. Its Grep search covers signals such as `.track(`, `ampli.`, `sendEvent`, Amplitude calls, and HTTP API usage.

The skill keeps direct SDK calls, typed methods, and custom wrappers as separate patterns, even when a wrapper delegates to the same API. It returns deduplicated patterns with generalized examples and file paths, then infers the event and property naming conventions used in those call sites. It checks `.amplitude/instrumentation-agent-context.md` first, including referenced files, because those customer rules override later inference. Run it before writing instrumentation code; that ordering is part of its workflow.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add amplitude/mcp-marketplace --skill discover-analytics-patterns -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add amplitude/mcp-marketplace --skill discover-analytics-patterns -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add amplitude/mcp-marketplace --skill discover-analytics-patterns -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install amplitude/mcp-marketplace discover-analytics-patterns
```

2. **Manually: put the files in place**
- File: `.github/skills/discover-analytics-patterns/SKILL.md`

npx skills add amplitude/mcp-marketplace --skill discover-analytics-patterns -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/amplitude/mcp-marketplace --path plugins/amplitude/skills/discover-analytics-patterns
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add amplitude/mcp-marketplace --skill discover-analytics-patterns -a opencode
```

### Claude.ai

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

## When to use it
- find actual event-tracking calls
- identify the SDK and function signatures in use
- separate analytics wrappers from direct SDK calls
- infer event and property naming rules
- prepare a consistent pattern for new events

## Example prompts
- Show how this codebase sends analytics events and include the file paths.
- Find the Amplitude tracking patterns used in this repository and generalize them.
- Work out the event and property naming conventions before adding new tracking.

description: >
  Discovers how analytics tracking calls are actually written in this codebase —
  the concrete SDK calls, function signatures, and import patterns used to send
  events. Use this skill whenever you need to understand the existing analytics
  instrumentation patterns before adding new tracking, when someone asks "how do
  we track events here?", "show me the analytics setup", "what's the analytics
  pattern in this codebase?", or any time the instrument-events or
  discover-event-surfaces skills are about to run and you need to know the
  correct coding style to follow. Outputs a deduplicated list of patterns with
  generalized examples and the file paths where each pattern appears, plus the
  dominant event and property naming conventions inferred from those call sites.
  Always use this skill before writing any analytics instrumentation code.

# discover-analytics-patterns

Your goal is to find out **how** this codebase sends analytics events — not which
events exist, but the specific code patterns engineers use to fire a tracking
call. This output helps engineers add new events that look consistent with the
rest of the codebase. It should also tell downstream skills how event names and
property names are typically written in code here.

When determining naming conventions in this skill, use the following sources in strict order of preference:
1. Customer directives in `.amplitude/instrumentation-agent-context.md` (and any files it references), if present — explicit conventions the customer wants followed, so they override everything below.
2. Events and properties observed from the Amplitude MCP server
3. Real tracking call sites in the codebase
4. The `taxonomy` skill at `../taxonomy/SKILL.md`

---

## Step 0: Read repo instrumentation context

Before anything else, check for `.amplitude/instrumentation-agent-context.md`
(repo root, or the subdirectory you're instrumenting). If it exists, read it and
any repo-relative files it references. Any naming conventions, property
standards, or SDK/wrapper patterns it states are **customer directives** — they
take precedence over everything you infer below; record them and skip inference
for whatever they cover. If it's absent, just continue — the `instrument-events`
skill owns prompting the user to add one.

---

## Step 1: Find tracking calls

Use two approaches based on what's available.

### If the Amplitude MCP is connected

Inspect the connected catalog and use its current taxonomy reader to fetch a
sample of event names from the project. Follow only the reader's advertised
