What it does

Orchardcore Workflow Activity is an agent skill from OrchardCMS/OrchardCore. Creates custom OrchardCore workflow activities — tasks and events — with their display drivers and registration. Use when the user needs a new workflow Task or Event, custom outcomes, activity editor UI, or to read/write workflow input, output, and properties.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/activities.md`).

The repository describes itself as: Orchard Core is an open-source modular and multi-tenant application framework built with ASP.NET Core, and a content management system (CMS) built on top of that framework. The licence is BSD-3-Clause.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Orchardcore Workflow Activity loads about 1.9k tokens when it runs, and up to ~3.1k if it reads all its reference files. Until then it costs about 73 tokens; SKILL.md has 445 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~73
When it runs · the whole SKILL.md, loaded when a task matches: ~1.9k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~3.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description: Creates custom OrchardCore workflow activities — tasks and events — with their display drivers and registration. Use when the user needs a new workflow Task or Event, custom outcomes, activity editor UI, or to read/write workflow input, output, and properties.

OrchardCore Workflow Activity

This skill guides you through writing custom workflow activities following project conventions.

A workflow is a graph of activities connected by outcomes. Two activity kinds:

Task — does work, then returns one or more outcomes (TaskActivity). Cannot start a workflow.
Event — waits for something to happen, halting the workflow until resumed (EventActivity). Can be a workflow start point.

Each activity pairs with a display driver that renders its thumbnail, design, and editor shapes, and is registered with services.AddActivity<TActivity, TDriver>().

Decide: Task or Event

Need	Use
Perform an action and continue (log, notify, HTTP call, set value)	`TaskActivity<T>`
Wait for / react to an external trigger (signal, timer, HTTP request)	`EventActivity`
Start a workflow	Event (tasks can't start)

Workflow

Step 1: Create the activity class

A task:

csharp

public class LogTask : TaskActivity<LogTask>
{
    private readonly IWorkflowExpressionEvaluator _expressionEvaluator;
    protected readonly IStringLocalizer S;

    public LogTask(IWorkflowExpressionEvaluator expressionEvaluator, IStringLocalizer<LogTask> localizer)
    {
        _expressionEvaluator = expressionEvaluator;
        S = localizer;
    }

    public override LocalizedString DisplayText => S["Log Task"];
    public override LocalizedString Category => S["Primitives"];

    // Persisted property — stored in the activity's Properties bag
    public WorkflowExpression<string> Text
    {
        get => GetProperty(() => new WorkflowExpression<string>());
        set => SetProperty(value);
    }

    public override IEnumerable<Outcome> GetPossibleOutcomes(WorkflowExecutionContext workflowContext, ActivityContext activityContext)
        => Outcomes(S["Done"]);

    public override async Task<ActivityExecutionResult> ExecuteAsync(WorkflowExecutionContext workflowContext, ActivityContext activityContext)
    {
        var text = await _expressionEvaluator.EvaluateAsync(Text, workflowContext, null);
        // ... do work ...
        return Outcomes("Done");
    }
}

An event halts in Execute, gates on CanExecuteAsync, and resumes in Resume:

csharp

public class SignalEvent : EventActivity
{
    public static string EventName => nameof(SignalEvent);
    public override string Name => EventName;

    public override LocalizedString DisplayText => S["Signal Event"];
    public override LocalizedString Category => S["HTTP"];

    public WorkflowExpression<string> SignalName
    {
        get => GetProperty(() => new WorkflowExpression<string>());
        set => SetProperty(value);
    }

    public override async Task<bool> CanExecuteAsync(WorkflowExecutionContext workflowContext, ActivityContext activityContext)
    {
        var signalName = await _expressionEvaluator.EvaluateAsync(SignalName, workflowContext, null);
        return string.Equals(workflowContext.Input.GetValue<string>("Signal"), signalName, StringComparison.OrdinalIgnoreCase);
    }

    public override IEnumerable<Outcome> GetPossibleOutcomes(WorkflowExecutionContext workflowContext, ActivityContext activityContext)
        => Outcomes(S["Done"]);

    public override ActivityExecutionResult Resume(WorkflowExecutionContext workflowContext, ActivityContext activityContext)
        => Outcomes("Done");
}

EventActivity.Execute returns Halt() by default — the workflow persists and waits.

Step 2: Create the display driver

csharp

public sealed class LogTaskDisplayDriver : ActivityDisplayDriver<LogTask, LogTaskViewModel>
{
    protected override void EditActivity(LogTask activity, LogTaskViewModel model)
        => model.Text = activity.Text.Expression;

    protected override void UpdateActivity(LogTaskViewModel model, LogTask activity)
        => activity.Text = new WorkflowExpression<string>(model.Text);
}

ActivityDisplayDriver<TActivity, TEditViewModel> wires thumbnail/design/edit shapes automatically. You only map between activity and view model.

Step 3: Create the shape templates

Three Razor shapes, named by activity:

Shape	File	Renders
Thumbnail	`LogTask_Fields_Thumbnail.cshtml`	activity picker entry
Design	`LogTask_Fields_Design.cshtml`	node on the workflow canvas
Edit	`LogTask_Fields_Edit.cshtml`	property editor form

Step 4: Register

In Startup.cs:

csharp

services.AddActivity<LogTask, LogTaskDisplayDriver>();

Step 5: Test

Build, open Admin → Workflows, create a workflow, drop your activity, wire its outcome, run. Events: trigger the external condition and confirm the halted workflow resumes.

Quick Reference

Required / common members

Member	Purpose
`Name`	technical id (defaults to type name via `TaskActivity<T>`)
`DisplayText`	localized label (`S["..."]`)
`Category`	grouping in the activity picker
`GetPossibleOutcomes(...)`	declares outcome ports
`ExecuteAsync(...)`	task work; return `Outcomes(...)`
`CanExecuteAsync(...)`	event gate (true → may run/resume)
`Resume(...)` / `ResumeAsync(...)`	event continuation after halt

Outcome & result helpers (from `Activity`)

Call	Meaning
`Outcomes("Done")`	continue down the `Done` port
`Outcomes("Yes", "No")`	multiple outcomes
`Halt()`	suspend (event waiting)
`Noop()`	empty result
`Outcomes(S["Done"])`	declare a possible outcome (in `GetPossibleOutcomes`)

Persisting state

GetProperty/SetProperty store into the activity's Properties JSON bag, keyed by member name ([CallerMemberName]):

csharp

public LogLevel LogLevel
{
    get => GetProperty(() => LogLevel.Information); // default if unset
    set => SetProperty(value);
}

Workflow-level data (`WorkflowExecutionContext`)

Dict	Use
`Input`	values supplied by the initiator (read)
`Output`	values returned to the initiator (write)
`Properties`	shared state between activities

csharp

workflowContext.Output["Result"] = value;
workflowContext.Properties["Counter"] = 1;
var signal = workflowContext.Input.GetValue<string>("Signal");

Gotchas

Use WorkflowExpression<string> for user-editable fields so authors can write Liquid/JS; evaluate with IWorkflowExpressionEvaluator.
Events must override Name to a stable value (often a static EventName) — other code references it by name to resume.
GetPossibleOutcomes returns Outcome objects (localized labels); ExecuteAsync returns ActivityExecutionResult via Outcomes("...") strings. Keep the names aligned.
Long-running events persist the workflow to the DB; don't hold non-serializable state on the activity between halt and resume.
