## What it does

The skill generates direct URLs for Logfire projects, Explore views, and specific traces. The agent avoids running `query_run` or downloading telemetry data when you only want the UI page. Telemetry queries happen only when an unknown target must be found first, such as locating the slowest span.

Inside Codex Desktop, the skill interacts with the in-app browser (`iab`) through an existing live view's JSON command bridge. It applies patches like `{"q":"level='error'","last":"1h"}` directly without triggering a full page reload. It explicitly refuses to launch external browser windows or Playwright: if in-app automation is unavailable, it outputs a clean URL in chat instead.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add pydantic/skills --skill logfire-ui -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add pydantic/skills --skill logfire-ui -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add pydantic/skills --skill logfire-ui -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install pydantic/skills logfire-ui
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add pydantic/skills --skill logfire-ui -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/pydantic/skills --path skills/logfire-ui
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add pydantic/skills --skill logfire-ui -a opencode
```

### Claude.ai

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

## When to use it
- open Logfire project live views or Explore pages directly
- generate direct links to traces using a known `trace_id`
- update filters on an open live view without document reloads
- prevent unneeded telemetry calls before opening the web interface

## Example prompts
- Open this project in Logfire live view
- Show this trace in the Logfire UI
- Give me a link to Explore filtered by errors

description: Open or return Logfire project pages, live views, trace links, and Explore pages in the Codex browser without querying telemetry first. Use this skill when the user asks to "open in Logfire", "show in the live view", "open Explore", "open the UI", "show in Codex", "use the browser", "give me a link", or asks for a Logfire GUI/browser/live-view presentation of a project, time range, service, span, trace, log, or filter. If "show" or "view" wording is ambiguous, ask whether the user wants a UI view or query analysis.

# Open Logfire UI

Use this skill for direct Logfire UI, browser, live-view, link, and Explore-page requests.

## User-Facing Progress

Keep progress updates quiet. Do not narrate why this skill was selected, restate routing rules, quote local instructions, explain token scope, or announce routine helper calls. If an update is needed, use one short sentence focused on the action, such as "Opening Logfire with the error filter."

After opening Logfire, do not run or narrate an extra page-state check unless the browser appears stuck, asks for login, or the user explicitly asked you to verify the page.

## Browser Targeting

In Codex Desktop, use the Browser plugin's Codex in-app browser (`iab`) and the currently selected tab whenever possible.

Browser access is indirect: do not expect a browser-named MCP tool. If the Browser plugin is listed as available, load the `browser:browser` skill and use its Node REPL `js` / `mcp__node_repl__js` bootstrap to bind `agent.browsers.get("iab")`. If `js` is not visible, use tool discovery for `node_repl js` before declaring the in-app browser unavailable.

Do not use `agent-browser`, `chrome-devtools`, `mcp__chrome_devtools__*`, `mcp__playwright__*`, macOS `open`, `xdg-open`, standalone Playwright/Chromium, a shell-launched browser, web preview cards, or a newly created external browser window unless the user explicitly asks for an external browser. Do not create a new in-app tab when a Logfire live view is already selected and can be updated in place.

Only report the in-app browser unavailable after the Browser plugin is not listed or its skill cannot be loaded, the Node REPL `js` execution tool is unavailable after tool discovery, or the Browser skill bootstrap fails before navigation starts. Then return the clean Logfire URL and explain that the in-app browser could not be controlled. Treat `chrome-devtools`, Playwright MCP, standalone Playwright, and web preview cards as "Browser unavailable", not as fallbacks. Do not silently fall back to any external or dedicated browser window.

## Core Rule

For project-level or aggregate UI requests, open or return Logfire directly by URL.

Do not query telemetry first:
- Do not call `query_run`.
- Do not say you will query Logfire or fetch spans first.

Only query first when the user asks to open a specific unknown item that must be found first, such as "open the slowest trace" or "open the latest error trace".

If the request is ambiguous, such as "show recent errors" or "view logs", ask whether the user wants Logfire opened in the UI or a query analysis in chat. Do not do both unless the user explicitly asks for both.
