Workflow Builder 🏗️

The meta-skill for designing and building autonomous OpenClaw workflows. A workflow (steward) is an autonomous agent that runs on a schedule, maintains state, learns over time, and does real work without prompting.

Skills vs Workflows:

• Skill = single-purpose tool (how to use a CLI, API, or pattern)
• Workflow = autonomous agent with state, learning, and scheduling

Part 1: Should You Automate This?

Not everything deserves a workflow. Use this framework to decide.

The Automation Audit

For any candidate task, score these dimensions:

Dimension	Question	Score
Frequency	How often? (daily=3, weekly=2, monthly=1, rare=0)	0-3
Repetitiveness	Same steps every time? (always=3, mostly=2, sometimes=1, never=0)	0-3
Judgment Required	Needs creative thinking? (none=3, low=2, medium=1, high=0)	0-3
Time Cost	Minutes per occurrence × frequency per month / 60 = hours/month	raw
Safety	How safe to automate? (harmless if wrong=3, annoying=2, costly=1, dangerous=0)	0-3

Decision:

• Score ≥ 10 + Time Cost > 2 hrs/month → Build a workflow
• Score 7-9 → Add to heartbeat checklist (batch with other checks)
• Score < 7 → Keep manual or add as a cron one-liner

ROI Calculator

Setup Time (hours) × $50 = Setup Cost
Time Saved (hours/month) × $50 = Monthly Value
Payback = Setup Cost / Monthly Value

< 2 months payback → Build it now
2-6 months → Build when you have time
> 6 months → Probably not worth it

Workflow vs Heartbeat vs Cron

Approach	When to Use
Workflow (steward)	Needs state, learning, rules, multi-step processing
Heartbeat item	Quick check, batch with others, context-aware
Cron (isolated)	Exact timing, standalone, different model
Cron (main)	One-shot reminder, system event injection

Rule of thumb: If it needs rules.md and agent_notes.md, it's a workflow. If it's a 2-line check, add it to HEARTBEAT.md.

Part 2: Workflow Anatomy

Every workflow follows this structure:

workflows/<name>/
├── AGENT.md          # The algorithm (updates with openclaw-config)
├── rules.md          # User preferences (never overwritten by updates)
├── agent_notes.md    # Learned patterns (grows over time, optional for some types)
├── state/            # Continuation state for multi-step work (optional)
│   └── active-work.json
└── logs/             # Execution history (auto-pruned)
    └── YYYY-MM-DD.md

AGENT.md — The Algorithm

This is the workflow's brain. It ships with openclaw-config and can be updated.

Standard sections (adapt to your workflow — not all are required):

---
name: <workflow-name>
version: <semver>
description: <one-line description>
---

# <Workflow Name>

<One paragraph: what this workflow does and why it exists.>

## Prerequisites

<What tools/access/labels/setup are needed before first run.>

## First Run — Setup Interview

<Interactive setup that creates rules.md. Ask preferences, scan existing data, suggest
smart defaults. Always let the user skip/bail early.>

rules.md — User Preferences

Created during first-run setup interview. Never overwritten by updates.

Pattern:

# <Workflow> Rules

## Account

- account: [e-mail]
- alert_channel: whatsapp (or: none, telegram, slack)

## Preferences

- <workflow-specific settings>

## VIPs / Exceptions

- <people or patterns to handle specially>

agent_notes.md — Learned Patterns

The workflow writes here as it learns. Accumulates over time.

Pattern:

# Agent Notes

## Patterns Observed

- <sender X always sends receipts on Fridays>
- <task type Y usually takes 2 hours>

## Mistakes Made

- <once archived an important email — now check for X before archiving>

## Optimizations

- <batch processing senders A, B, C saves 3 API calls>

logs/ — Execution History

One file per day, auto-pruned after 30 days.

Pattern:

# <Workflow> Log — YYYY-MM-DD

## Run: HH:MM

- Processed: N items
- Actions: archived X, deleted Y, alerted on Z
- Errors: none
- Duration: ~Ns

---

Part 3: Design Patterns

Pattern 1: Setup Interview

Every workflow should start with an interactive setup that creates rules.md.

Best practices:

1. Check prerequisites first (API access, labels, etc.)
2. Ask questions one category at a time
3. Offer smart defaults based on scanning existing data
4. Let the user skip or bail early ("looks good, skip to the end")
5. Summarize rules in plain language before saving
6. Always include an escape hatch: alert_channel: none

Pattern 2: Graduated Trust

Start conservative, get more aggressive as confidence grows.

Week 1: Only act on obvious items (>95% confidence)
Week 2: Expand to likely items (>85% confidence), log edge cases
Week 3: Review agent_notes.md, adjust thresholds
Week 4+: Stable operation with periodic self-audit

Write confidence thresholds to rules.md so the user can tune them.

Pattern 3: Sub-Agent Orchestration

Match intelligence to task complexity:

Obvious/routine items → Spawn sub-agent (cheaper model: Haiku/Sonnet)
Important/nuanced items → Handle yourself or spawn a powerful sub-agent (Opus)
Quality verification → Can use a strong model as QA reviewer (Opus as sub-agent)
Uncertain items → Sub-agents escalate to you rather than guessing

Note: Don't hardcode model IDs (they go stale fast). Use aliases like sonnet, opus, haiku or reference the model by capability level.

Pattern 4: State Externalization (Compaction-Safe)

Critical: Chat history is a cache, not the source of truth. After every meaningful step, write state to disk.

# state/active-work.json (or inline in agent_notes.md)

{ "current_phase": "processing", "next_action": "Review batch 2 of inbox",
"last_completed": "Batch 1: archived 12, deleted 3", "resume_prompt": "Continue inbox
processing from message ID xyz", "updated_at": "2026-02-18T14:30:00Z" }

Rule in AGENT.md: "On every run, read state first. Either advance it or explicitly conclude it."

Pattern 5: Error Handling & Alerting

Every workflow must handle failures gracefully:

1. Log errors to daily log with full context
2. Alert on critical failures (unless alert_channel: none)
3. Never fail silently — if something breaks, the human should know
4. Quarantine, don't destroy — use labels/tags, not deletion
5. Route all errors to one place — consistent error channel

Pattern 6: Integration Points

Workflows should declare how they connect to other workflows:

## Integration Points

### Receives From

- email-steward: Emails needing follow-up → creates task

### Sends To

- task-steward: Creates tasks when work is discovered
- message channel: Alerts when human attention needed

### Shared State

- None (or: reads from workflows/shared/contacts.md)

---

Part 4: Scheduling & Execution

How Workflows Run

Workflows are triggered by cron jobs (isolated sessions):

# Example: email steward runs every 30 minutes during business hours
openclaw cron add \
  --name "Email Steward" \
  --cron "*/30 8-22 * * *" \
  --tz "YOUR_TIMEZONE" \
  --session isolated \
  --message "Run email steward workflow. Read workflows/email-steward/AGENT.md and follow it." \
  --model sonnet \
  --announce

Cron Configuration Guidelines

Workflow Type	Schedule	Model	Session
High-frequency triage (email, notifications)	Every 15-30 min	Sonnet	Isolated
Daily reports/summaries	Once daily at fixed time	Opus	Isolated
Weekly reviews/audits	Weekly cron	Opus + thinking	Isolated
Reactive (triggered by events)	Via webhook or system event	Varies	Main or Isolated

Delivery

• Routine runs: Omit --announce (or set delivery to none) — work silently, only alert when something needs attention
• Reports/summaries: Use --announce — delivers a summary to the configured channel after completion
• Errors/alerts: Always deliver via the workflow's configured alert channel

Note: Isolated cron jobs default to announce delivery (summary posted after run). Set delivery: none explicitly if you want silent operation.

Part 5: Building a New Workflow

Step-by-Step Process

1. Identify the opportunity (use the Automation Audit above)
2. Define the scope — What does "done" look like for one run?
3. List prerequisites — What tools, access, labels are needed?
4. Design the setup interview — What preferences does the user need to set?
5. Write AGENT.md — The algorithm, following the anatomy above
6. Test manually — Run the AGENT.md instructions yourself first
7. Set up cron — Schedule for autonomous operation
8. Monitor first week — Watch logs, tune rules, build agent_notes

AGENT.md Template

---
name: <name>-steward
version: 0.1.0
description: <one-line description>
---

# <Name> Steward

<What this workflow does and why.>

## Prerequisites

- **<Tool>** configured with <access>
- **<Labels/tags>** created: <list>
- **Alert channel** configured (or none)

## First Run — Setup Interview

If `rules.md` doesn't exist or is empty:

### 0. Prerequisites Check

<Verify all tools and access work.>

### 1. Basics

<Core configuration questions.>

### 2. Preferences

<How aggressive, what to touch, what  >





















 Read  for preferences
 Read  for learned patterns (if exists)
 
 
 Alert if anything needs attention
 Append to today's log in 
 Update  if you learned something







 Delete logs older than 30 days
 

Checklist Before Deploying

• AGENT.md follows the standard anatomy
• Setup interview creates rules.md with all needed preferences
• Has clear judgment guidelines (when to act vs leave alone)
• Error handling: logs errors, alerts on critical failures
• Housekeeping: auto-prunes old logs
• Integration points documented
• Cron job configured with appropriate schedule/model
• First week monitoring plan in place

Part 6: Maintaining Workflows

Monthly Audit (15 min per workflow)

For each active workflow:

1. Review logs — Any recurring errors? Silent failures?
2. Check agent_notes.md — Has it learned useful patterns?
3. Review rules.md — Still accurate? Preferences changed?
4. ROI check — Still saving time? Worth the token cost?
5. Integration health — Connected workflows still working?

When to Retire a Workflow

• ROI drops below 1x (costs more than it saves)
• The underlying process changed significantly
• A better approach exists (new tool, API, or workflow)
• It causes more problems than it solves

To retire: disable the cron job, archive the workflow directory, note in memory/decisions/.

Part 7: Security Considerations

For Workflows from ClawHub

⚠️ ClawHub has had malicious skills. Before installing any workflow:

1. Inspect before installing: npx clawhub inspect <slug> --files
2. Check for VirusTotal flags: ClawHub scans automatically; heed warnings
3. Download to /tmp for review: npx clawhub install <slug> --dir /tmp/review
4. Review all files manually — look for:
   • External API calls to unknown domains
   • Eval/exec of dynamic code
   • Hardcoded API keys or crypto addresses
   • Instructions to disable safety features
   • Data exfiltration patterns (sending data to external services)
5. Never install directly into your workspace without review

For Your Own Workflows

• Workflows should only access tools they need
• Alert channels should be explicit (no silent external sends)
• Quarantine before delete (labels > trash > permanent deletion)
• Log all actions for auditability

Existing Workflows Reference

email-steward

• Purpose: Inbox debris removal
• Schedule: Configured via cron (typically every 30 min during business hours)
• Tools: gog CLI (Gmail)
• Key pattern: Setup interview → graduated trust → sub-agent delegation
• Notable: Uses agent_notes.md heavily for learning sender patterns

task-steward

• Purpose: Task board management with QA verification
• Schedule: Can run via heartbeat or cron (see its AGENT.md for guidance)
• Tools: Asana MCP
• Key pattern: Task classification → work execution → quality gate (Opus QA) → delivery
• Notable: Spawns Opus as QA sub-agent — demonstrates strong model as worker, not just orchestrator
