P0–P3 findings
Impact, likely cause, and reproduction conditions ranked by urgency.
ASYNC / FIXED SCOPE / NO LIVE ACCESSDiagnose one n8n workflow.
Diagnose one n8n workflow.
In writing.
For a workflow that stops, duplicates work, or reports success with the wrong output. I review one sanitized inactive export and return a prioritized repair plan within three business days.
The first email is for scope only. Do not attach files or secrets.
DELIVERABLE LEDGERA repair decision,
A repair decision,
not a vague review.
Each finding is tied to observable behavior and an acceptance check.
Fix order
A bounded sequence that separates immediate containment from durable changes.
Acceptance tests
Normal, retry, duplicate, invalid-input, and sustained-failure checks when relevant.
Written answer
One follow-up question submitted within seven days after delivery.
INPUT BOUNDARYSanitize first.
Sanitize first.
Share later.
I do not need your production login, live credentials, or a call. Materials are requested only after scope and sharing method are confirmed in writing.
Accepted after confirmation
- One inactive workflow JSON export
- Up to five execution or error screenshots
- A short expected-versus-observed description
- An access-restricted sharing link
Remove before sharing
- Credential IDs and credential bodies
- Passwords, API keys, tokens, cookies, and signed URLs
- Personal, customer, vendor, or internal business data
- Real payloads that are not required to reproduce the issue
Working copies are deleted no later than 21 days after delivery, including when no follow-up question is submitted. If secret or personal data is received accidentally, work stops; the material is deleted and the sender is notified so affected credentials can be rotated.
PUBLIC SYNTHETIC LAB
Evidence before claims.
This is a synthetic lab artifact, not a client engagement or testimonial.

FOUR WRITTEN STEPS
No meeting required.
An inquiry does not create a contract. Scope, price, delivery, and acceptance conditions are agreed first.
- 01Describe
Send the symptom, expected result, observed result, and n8n version. No attachments.
- 02Confirm
I confirm fit, exclusions, sharing method, payment route, and start date in writing.
- 03Share
After agreement, share sanitized inputs through the confirmed restricted link.
- 04Receive
Get the written diagnostic and acceptance tests within three business days.
NOT A FIT
This service stops at diagnosis.
- Emergency incident response or an on-call support requirement
- Live production access, credential setup, or secret handling
- Multiple workflows, a full rebuild, or open-ended implementation
- Medical, legal, investment, or other high-stakes automated decisions
FIXED IMPLEMENTATION / ONE WORKFLOWNeed the workflow built,
Need the workflow built,
not only diagnosed?
One bounded implementation. No open-ended consulting, no hidden expansion after work starts.
BUILD / TEST / HANDOFF
Small n8n implementation pack
JPY 132,000fixed total; includes Japanese consumption tax when applicable
One business path delivered as one testable workflow, with a defined failure path and a handoff package.
Fixed ceiling
- One n8n workflow
- Up to eight main processing steps
- Up to three connected services
- Normal-path and principal failure-path acceptance tests
- Workflow export, configuration map, operations and recovery notes
- In-scope defect correction for 14 days after delivery
Target delivery: ten business days after required materials and scoped access are received.
Describe one workflow outcomeBOUNDARIES / BEFORE START
Production control stays with you
The first email contains scope only. Credentials and customer data are never requested there.
Not included
- Provider, API, VPS, SaaS, or transfer fees
- More workflows, services, or steps than the fixed ceiling
- 24/7 monitoring, on-call support, or open-ended maintenance
- Medical, legal, investment, or other high-stakes decisions
- Publishing, sending, or charging without a human approval gate
Scope, exclusions, payment route, start date, and acceptance conditions are agreed in writing before work begins.
Inspect a bounded prototypeSTART WITH THE SYMPTOMOne workflow.
One workflow.
One written decision.
Describe what should happen, what happens instead, and your n8n version. I will reply with fit, exclusions, and the next safe step. No files in the first email.
