# profilecli-insights

This skill pulls live profiles from a Pyroscope server with profilecli, reads them through pprof, and ties hot functions back to the code in your checkout.

## What it does

The skill walks the agent through seven ordered steps. First it checks that `profilecli` is on PATH and picks an analyzer: `pprof`, or `go tool pprof` when the standalone binary is missing. Then it runs a series query to confirm the connection works and to list the available profile types — CPU, allocations, in-use memory, goroutines, mutex and block contention.

Next it lists services and compares their `service_repository` against `git remote get-url origin`, flagging repository matches as the most relevant. The profile is written to a temp file via `mktemp`, analyzed with `-lines -top -cum`, and hot frames are mapped to source lines: the module prefix is stripped, and frames carrying an `@version` suffix are treated as third-party. If the Build ID contains a `git_ref` that differs from the latest commit, the skill warns that line numbers may be stale.

Setup is small but real: `profilecli` and `pprof` on PATH plus access to a Pyroscope-compatible server. `PROFILECLI_URL` is required, and Grafana Cloud also needs `PROFILECLI_TOKEN` — a service account token in `glsa_...` format with the Viewer role. Without a working connection the skill stops and waits for you to fix the environment. That is fair: there is nothing to analyze without data.

## Requirements
- Works with: Grafana

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill profilecli-insights -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill profilecli-insights -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill profilecli-insights -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install grafana/skills profilecli-insights
```

2. **Manually: put the files in place**
- File: `.github/skills/profilecli-insights/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill profilecli-insights -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/grafana/skills --path skills/grafana-lgtm/profilecli-insights
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add grafana/skills --skill profilecli-insights -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/grafana/skills/tree/HEAD/skills/grafana-lgtm/profilecli-insights/SKILL.md

## When to use it
- find which function burns the most CPU in a service
- separate allocation pressure from garbage collection overhead
- map a hot profile frame to a line in the source file
- check whether line numbers went stale after recent commits
- trace where mutex and block contention comes from

## Example prompts
- look at the CPU profile for the distributor service over the last hour
- which functions are hottest in this service and what can I fix in them
- correlate the hot functions with the code in this repo and suggest optimizations

# Profilecli Insights

You are a performance analysis assistant. Query a remote Pyroscope continuous profiling server with `profilecli`, then correlate the results with source code in the current repository to provide actionable insights.

Follow these steps in order. Do not skip steps.

## Step 1: Ensure profilecli is available

Check that `profilecli` is on PATH:

```bash
profilecli --version
```

If it is not found, instruct the user to download it from `https://github.com/grafana/pyroscope/releases/latest/download/`.

Select the command to use for all later profile analysis:

```bash
if command -v pprof >/dev/null 2>&1; then
  PPROF=(pprof)
else
  PPROF=(go tool pprof)
fi
```

## Step 2: Verify connectivity and data exists

Run a series query to validate the connection and discover profile types:

```bash
profilecli query series --label-names=__profile_type__ --output json
```

If this succeeds, parse the JSON output and retain the available `__profile_type__` values. Common types include:

- `process_cpu:cpu:nanoseconds:cpu:nanoseconds` (CPU)
- `memory:alloc_space:bytes:space:bytes` (memory allocations)
- `memory:inuse_space:bytes:space:bytes` (memory in-use)
- `goroutine:goroutine:count:goroutine:count` (goroutines)
- `mutex:contentions:count:contentions:count` (mutex contention)
- `block:contentions:count:contentions:count` (block contention)

You need these profile types in Step 4.

If the query fails, help the user configure the connection:

- Run a local Pyroscope server on port `4040`.
- Or connect to Grafana with a service account token.
