webui

webui is a skill for Claude Code from vinnie357/claude-skills. It costs 30 tokens per session (696 once invoked), scanned A, original, MIT.

A browser-based interface for Dagu, a tool that runs scheduled workflows made of connected steps. It lets you manage workflows and inspect their runs, logs, and history.

In plain words
What is it for?
Use it to start or stop Dagu workflows, watch progress, read execution logs, review past runs, and configure schedules.
Why use it?
It removes the need to use command-line commands to see whether workflows are running or why they failed. The visual workflow view also makes step dependencies easier to follow.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

webui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Dagu Web UI

Use this skill when working with Dagu's web interface to manage workflows, view execution history, monitor running workflows, or configure the UI.

Core Capabilities

The Dagu Web UI provides:

  1. Workflow Management - View, start, stop, and manage workflows
  2. Execution Monitoring - Real-time status and logs
  3. History Viewing - Past execution records and results
  4. DAG Visualization - Visual representation of workflow structure
  5. Log Access - View detailed execution logs
  6. Schedule Management - Configure when workflows run

Quick Start

Access Dagu Web UI at http://localhost:8080 (default) after starting Dagu:

dagu server

Primary Operations

Start a Workflow

To manually execute a workflow:

  1. Navigate to workflow list
  2. Click the workflow name
  3. Click "Start" button
  4. View real-time execution progress

Monitor Execution

For detailed information on a running workflow, consult references/monitoring.md which covers:

  • Reading execution logs
  • Understanding status indicators
  • Tracking step progress
  • Identifying failures

View History

Execution history is not unconditionally preserved — the REST API supports deleting individual records (DELETE /dags/{dagName}/history/{requestId}, see /dagu:rest-api references/api-endpoints.md "Delete Execution History"). Open a workflow's history to review past runs, find failed executions, and retry them (see Common Tasks).

Workflow Visualization

The DAG view shows workflow structure. Click step names in the DAG view for step-specific details.

When to Consult References

Read references/monitoring.md for execution status indicators, real-time log viewing, progress tracking, error detection, and troubleshooting stuck workflows.

Common Tasks

Restart a Failed Workflow

  1. Find the failed execution in history
  2. Click the retry/restart button
  3. Monitor the new execution

Stop a Running Workflow

  1. Navigate to the running workflow
  2. Click "Stop" or "Cancel"
  3. Confirm the action
  4. View cleanup handlers execution

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
