Skill Claude Code
Iterate on UI with a person watching and giving live visual feedback. Pointer skill: the person uses their own tab on the stack and the haven orb; you read their notes and check fixes with haven browser. Use when the user says 'browser pair', 'paired browser', 'let's look at this together', 'open chromium', or wants…
Skill Claude Code
Check that a feature works by walking its scenarios in a real browser and writing a pass/fail report with evidence. A recipe over haven browser: no test files, no browser commands of its own. Use when someone says 'browser test', 'verify this in the browser', 'walk the scenarios', 'check the feature live', or hands…
Skill Claude Code
Maintain the canonical LangWatch feature map (feature-map.json at the repo root) and its human-readable companion FEATUREMAP.md. Use when adding or renaming a feature, a REST namespace, a UI route, an MCP tool, a CLI command or a user-facing skill, so the central registry keeps naming what the code actually serves.…

Records which repository and branch each coding-agent session worked in, and teaches the agent to read its own traces back from LangWatch.
Skill Claude CodeCodex
Expert AI engineering consultant for your agent development practices. Audits your codebase, traces, evaluations, and scenarios against best practices, then guides you to close the gaps, starting from low-hanging fruit and going deeper. Use when you want to level up your agent's engineering quality.
Skill Claude CodeCodex
Turns production evidence into tested improvements for your AI agent. Forms hypotheses from real traces and analytics, explains the reasoning behind each one, then executes with the user: scenario tests that reproduce production failures, prompt and code changes as reviewable PRs, new evaluators and monitors that…
Skill Claude CodeCodex
Deep-dive diagnosis of how your AI agent behaves in production. Explores LangWatch analytics and traces end to end to map failure patterns, dissatisfied users, token cost hotspots, edge cases, behavior changes, and outliers, then delivers an HTML report where every finding links to real example traces. Use when you…
Skill Claude CodeCodex
Connect the codebase's AI agent to LangWatch agent simulations, so test suites run against the real agent process. Adds a small connect function beside the service startup that calls the agent already in the codebase, which opens an outbound connection and registers the agent with its environment and its run…
Skill Claude CodeCodex
Investigates the context economics of your own coding-agent sessions in LangWatch. Reads real sessions to find where carrying a fat context stops paying for itself, measured in cache rebuilds, compactions and cost per turn, and delivers a report with the context size your sessions should stay under, with example…
Skill Claude CodeCodex
Generate realistic synthetic evaluation datasets by analyzing the user's codebase, prompts, production traces, and reference materials. Interactive and consultant-style. Asks clarifying questions, proposes a plan, generates a preview for approval, then delivers a complete dataset uploaded to LangWatch. Use when user…
Skill Claude CodeCodex
Debug and improve your LangWatch traces. Inspects production traces for missing input/output, disconnected spans, unlabeled traces, and missing metadata. Use when traces look broken or incomplete.
Skill Claude CodeCodex
Root-cause production errors and misbehaving agent runs with LangWatch. Finds errored traces, inspects spans, checks monitor and evaluator scores, then narrows to a root cause. Use when something is failing or misbehaving in production (errors, bad answers, latency spikes).
Skill Claude CodeCodex
Drive the page the user has open through live UI actions. List the actions a page accepts, call them with typed payloads, and read the live state including unsaved edits. Use when the user is looking at a page you can operate, such as the evaluations workbench, and a change should happen in front of them rather than…
Skill Claude CodeCodex
Investigate failing experiments and evaluations with LangWatch. Triage a failing experiment run to the exact rows and evaluator scores that regressed, then to a root cause. Use when an experiment fails, scores drop, or evaluations regress.
Skill Claude CodeCodex
Evaluate multimodal AI agents that process images, audio, PDFs, or other files. Sets up evaluations using LangWatch's LLM-as-judge with image inputs, Scenario's multimodal testing, and document parsing evaluation patterns. Use when your agent handles non-text inputs.
Skill Claude CodeCodex
Compatibility router for LangWatch evaluation requests. Use only when the user asks for evaluations without making it clear whether they mean pre-deployment experiments or production online evaluations. Routes the request to the focused companion skill and does not implement either workflow itself.
Skill Claude CodeCodex
Create and run LangWatch experiments for pre-deployment batch testing. Use when the user wants to test an agent against a dataset, compare prompts or models, benchmark quality, detect regressions, or add a CI quality gate. Do not use for production monitoring or guardrails.
Skill Claude CodeCodex
Generate a synthetic evaluation dataset from your RAG knowledge base. Creates diverse Q&A pairs with expected answers and relevant context, ready for LangWatch experiments and platform import. Use when you need test data for your RAG pipeline.
Skill Claude CodeCodex
Open a real pull request. Clone a repo, branch, commit, push, and open a PR authored by the LangWatch app on behalf of the requesting user. Use when the user asks to open a PR, fix something in a repo and submit it, send a patch, raise a pull request, or otherwise land a code change on GitHub.
Skill Claude CodeCodex
Take your AI agent to the next level with full LangWatch integration. Adds tracing, prompt versioning, evaluation experiments, and simulation tests in one go. Use when the user wants comprehensive observability, testing, and prompt management for their agent.
Skill Claude CodeCodex
Author a saved analytics chart from a plain question and place it on a dashboard. Discovers the LangWatchQL analytics schema, writes and test-runs the SQL, saves it as a chart with a Vega-Lite specification, and places it where the team already looks. Use when asked to build, save, run, or dashboard a metric or chart.
