Journey Submit

Journey: Hackathon submission

Stage 5 (final) of the guided journey. Resolve the active hackathon, confirm fields, submit.

When to use

• Dispatched by journey when current_stage: submit and hackathon_mode: true.
• Directly via /butterbase-skills:submit.
• No-op (returns with "submit is disabled outside hackathon mode") if hackathon_mode: false.

Preflight

If docs/butterbase/03-preflight.md is missing, older than 24 hours, or 00-state.md has app_id: null, invoke butterbase-skills:journey-preflight first. Wait for it to return successfully before proceeding.

Additionally: refuse to run unless deploy is ticked in 00-state.md. If it is not, tell the user to run /butterbase-skills:journey-deploy first.

Inputs

• docs/butterbase/01-idea.md — title / tagline candidates.
• docs/butterbase/02-plan.md — feature list.
• docs/butterbase/04-build-log.md — what actually shipped.
• docs/butterbase/00-state.md — app_id, deployed_url.

Procedure

Step 1 — Prep (resolve which hackathon)

Always start with action: "prep". Do not assume there is exactly one hackathon, and do not invent a field schema from prior context — the platform owns the schema and it varies per hackathon.

// First, ask the user: "Do you have a submission code from the organizer? (paste it, or 'no')"
// If yes, pass it. If no, omit it.
{
  "tool": "prep_and_submit_hackathon_entry",
  "arguments": {
    "action": "prep",
    "submission_code": "<optional, from user>"
  }
}

The response shape is:

{
  "matched": null | { "slug", "name", "submission_deadline", "ends_at", "field_schema": { "fields": [...] } },
  "match_reason": null | "submission_code" | "already_bound" | "single_open",
  "open_hackathons": [{ "slug", "name", "starts_at", "ends_at", "submission_deadline" }, ...],
  "next_call": { ... }   // present only when matched is non-null
}

Branch on the result:

matched	open_hackathons.length	Action
non-null	any	Resolved — continue to Step 2 with matched.field_schema. Mention match_reason to the user ("Resolved via your submission code", "You're already a participant in X", "Only one hackathon is open: X").
null	0	No hackathon is currently open for submissions. Tell the user, stop, and do not tick submit.
null	1	One hackathon is open but the user isn't bound and didn't supply a code. Ask: "The only open hackathon is '<name>' (deadline <submission_deadline>). Submit to this one? If so, paste the submission_code the organizer gave you." Re-run prep with the code.
null	≥ 2	Multiple open hackathons — ask the user which one. Present the list (name, slug, deadline) and ask: "Which hackathon are you submitting to? Paste its submission_code." Re-run prep with the code. Never guess.

Anti-pattern: do not re-run prep in a loop hoping it resolves — it won't until the user provides a submission_code. One question, then re-prep.

Step 2 — Walk the returned field_schema with the user

matched.field_schema.fields is the authoritative list of fields for this hackathon. Walk every field in order. For each:

1. Show the user the field's label (not key) and description.
2. Propose a value drawn from journey artifacts where obvious:
   • URL-typed fields (is_url: true or type: "url") for the deployed app → deployed_url from 00-state.md.
   • Project name / title field → top candidate from 01-idea.md.
   • Description / summary field → one-liner from 01-idea.md + must-haves.
   • Repo URL → ask, no default.
   • Team info → ask, no default.
   • Demo video → ask, allow skip if required: false.
   • Anything else → ask.
3. Confirm one at a time. Do not batch. Required fields must have a non-empty value before moving on.
4. For options-typed fields, present the allowed choices verbatim.

Use next_call.arguments.data from the prep response as the literal template — it has one key per field with a placeholder string. Replace each placeholder with the confirmed value.

Step 3 — Submit

Show the assembled data object back to the user verbatim and ask: "Submit now? (yes/no)". On yes:

{
  "tool": "prep_and_submit_hackathon_entry",
  "arguments": {
    "action": "submit",
    "hackathon_slug": "<matched.slug from prep — REQUIRED when multiple are open>",
    "app_id": "<app_id from 00-state.md — strongly recommended, unlocks +50 scoring points>",
    "submission_code": "<same code passed to prep, if any — required on first submission>",
    "data": { /* user-confirmed values keyed by field.key */ }
  }
}

Always pass hackathon_slug = matched.slug from prep. Without it, submit re-resolves and may target a different hackathon if more than one is open. Always pass app_id — scoring awards up to 50 points for Butterbase usage on that specific app.

Step 4 — Receipt

Capture the response (submission.id, submission.version, submission.updated_at, participant_created) and write docs/butterbase/05-submission.md:

# Submission

- submitted_at: <submission.updated_at>
- submission_id: <submission.id>
- version: <submission.version>
- hackathon_slug: <submission.hackathon_slug>
- hackathon_name: <matched.name>
- app_id: <submission.app_id>
- participant_created: <true|false>

## Fields submitted
<one bullet per field: label → value>

Tick - [x] submit in 00-state.md, set current_stage: done. Print a one-line success to the user including the hackathon name and submission id.

Outputs

• Hackathon submission via prep_and_submit_hackathon_entry (action: "prep" then "submit").
• docs/butterbase/05-submission.md.

Anti-patterns

• ❌ Skipping action: "prep" and calling submit directly with a hardcoded field list.
• ❌ Assuming there is exactly one open hackathon. Always check open_hackathons on the prep response.
• ❌ Picking a hackathon for the user when prep returns multiple — always ask.
• ❌ Inventing field keys or labels — only use what's in matched.field_schema.fields.
• ❌ Submitting without hackathon_slug from prep (can re-resolve to the wrong hackathon).
• ❌ Submitting without app_id when one exists (forfeits up to 50 scoring points).
• ❌ Calling submit without explicit yes from the user on the assembled payload.
