Workflow Structure

The standard anatomy of a workflows/*.md document, and what makes one compliant.

Required sections

# Workflow: <Name>

## When to use
## Inputs required
## Output
## Subtasks (or "Phases")
  • When to use - trigger conditions, so a router (human or model) can match a request to this workflow without reading the whole file.
  • Inputs required - named parameters the caller must supply.
  • Output - what gets written and where (file path, or "returned to caller").
  • Subtasks/Phases - the ordered steps. Each one states:
    • Who does it - main thread or subagent, with model tier (Haiku/Sonnet/Opus) if a subagent
    • Must read - any file the step needs, if applicable
    • Do - the concrete instructions

Ownership clarity

Every subtask/phase must unambiguously assign ownership:

  • Main-thread tasks require user interaction or judgment about scope
  • Subagent tasks are dispatched with an explicit model tier
  • A main-thread step must never silently perform subagent-tier work (file writes, content drafting) — delegate it

Completeness checklist

  • Purpose and trigger conditions are clear
  • Inputs are well-defined (names, not just prose)
  • Output format and location specified
  • Every subtask/phase has necessary context (what to read)
  • Verification step included if the workflow modifies files
  • No missing steps in the flow (a reader could execute this cold)

Quality bar

  • Logical step ordering — later steps don't need something an earlier step hasn't produced yet
  • Subagent model assignments match the work (mechanical → Haiku, drafting/ analysis → Sonnet, judgment/synthesis → Opus)
  • File artifacts (task docs, scratch files) are passed between phases by path, not assumed shared context
  • No redundant steps

Minimal skeleton

# Workflow: <name>

## When to use

- <trigger 1>
- <trigger 2>

## Inputs required

- **<input_name>** - <description>

## Output

- <what gets written, and where>

---

## Subtasks

### 1. <step name>

Subagent: <main | haiku | sonnet | opus>.
Read: <files this step needs, if any>

**Do:**
- <instruction>
