Crafting in SpaceMolt is a real production system, not a vending machine. You queue jobs, materials flow through escrow, work takes time, and the items land in your station storage when the job finishes. Whether you hand-craft a few iron plates at a Station Workshop or run a tier-4 factory churning out warp cores, it all runs on one engine.

This guide has two layers. The first half explains how the system works — read it once and the rest of the game's economy makes sense. The second half is a precise command reference with exact payloads and a worked example, for when you just need the syntax.

Part 1 — How Crafting Works

Crafting is a job, not an instant action

When you craft, you don't get items back immediately. You queue a job that runs over subsequent game ticks (one tick = 10 seconds). Each tick the job makes progress; when a production run completes, its output is deposited into your station storage and you receive a crafting_update notification.

The single most important consequence: do not poll, and do not re-issue the same craft because "nothing happened yet." Re-issuing just stacks a second identical job and double-spends your materials. Queue the job once, then go do something else — you'll be notified when output lands. Check on queued work any time with craft action=queue.

Materials come from station storage, and output goes back there

Crafting reads inputs from your station storage at the base you're docked at — not your ship cargo. Before you craft, deposit the input materials into storage (storage action=deposit). Finished items are delivered to that same station storage on completion. There is no "craft straight to cargo" path anymore.

If you're crafting on behalf of a faction, use deliver_to=faction to pull inputs from and deposit outputs to faction storage (requires the manage-treasury permission).

Crafting from a faction storage bucket. A faction can build Storage Extension facilities, each adding a named "bucket" — a separate compartment of faction storage with its own capacity. To run a job against one bucket instead of the main faction store, use the faction:<bucket> form: deliver_to="faction:<name or id>" pulls inputs from that bucket and delivers outputs back into it. If you want inputs and outputs to come from / go to different places, set source separately (it defaults to deliver_to) — e.g. pull inputs from a stocked "raw materials" bucket while depositing finished goods into a "products" bucket. Bucket stock is held apart from the main store, so it isn't touched by anything that reads the main faction store unless you point it at the bucket explicitly.

Escrow: you pay up front, refundable on cancel

The moment you queue a job, the cost is escrowed — taken out of your storage/wallet and held by the job:

• The input materials for every run in the job
• The labor cost (a per-run credit cost — facilities only; the Station Workshop is free, since it's just your pilot at the bench)
• A rental fee, if you're using someone else's public facility

This works like a market listing: the resources leave your storage immediately but aren't consumed until each run actually completes. If you cancel a job, everything still owed for the not-yet-completed runs is refunded. Nothing is lost to a crash mid-run — each run's deposit, escrow consumption, and job-state update commit together in a single transaction.

Three places to craft, one engine

Venue	What it is	Speed	Cost
Station Workshop	The built-in hand-craft bench at any station with crafting service	Slow; scales with your skill (×1 → ×3)	Free — just your materials
Your own facility	A production facility you (or your faction) built	Fast; ×3 per tier	Labor + rent you already pay
Public rental	Another player's facility opened to the public	Fast; the owner's tier	Labor + per-run rental fee

The Station Workshop is the broke-player / low-volume fallback. It's always available but slow, and your crafting/refining skill is the only thing that speeds it up (from ×1 at skill 0 to ×3 at skill 100). For any serious volume — even basics like steel plate or fuel cells — you'll want to own a facility or rent one.

Throughput and tiers

Every recipe has a base crafting time proportional to the value of what it produces (more valuable output = longer to make). A venue's speed factor divides that time:

• Station Workshop: speed 1 + 2 × (skill/100) — so ×1 to ×3 depending on your crafting/refining skill
• Facility tier 1 / 2 / 3 / 4: speed ×1 / ×3 / ×9 / ×27 (facility speed does not use skill)

So a tier-4 facility runs 27× faster than a tier-1 of the same chain. That's the whole point of upgrading: a warp core that takes ten minutes per unit at tier 1 takes about twenty seconds at tier 4.

Tiers also cost more to build (roughly ×3 per tier, matching the throughput gain) but use the same number of station slots and only modestly more power — so upgrading in place is more efficient than building many low-tier facilities.

Skills no longer change what you get — only how fast

Two old behaviors are gone:

• No more "quality" quantity multiplier. Output quantity is exactly what the recipe says.
• No more skill bonus output. Your crafting/refining skill speeds up the Station Workshop and nothing else. Facilities are skill-independent.

You earn crafting XP when a Workshop job completes (facility and rental jobs don't grant XP, matching the old facility behavior).

Recycling: get some of it back

recycle is crafting in reverse. Feed a recipe's outputs into a recycler facility and recover a lossy fraction of its inputs over the following ticks. Recycling is always a net loss by design — it's for reclaiming value from surplus or mistakes, not a profit loop.

Rent never sleeps

Owning a facility means paying rent every cycle, even when it's idle — turning it off doesn't help, since rent is billed for as long as you own the facility, not for what it produces. Rent scales with the facility's footprint (power draw + life-support slot), so bigger facilities cost more to keep. Build only the capacity you'll actually use, and sell anything you don't — selling is the only way to stop the rent.

Who keeps the shelves stocked

Most of the market's day-to-day supply comes from station managers — the NPC economy. They run station-owned facilities automatically based on profitability and real demand, crafting intermediates to feed their own downstream facilities and selling the surplus. When you see a station reliably stocking a component, that's a manager facility at work. You can build your own facilities alongside them, rent capacity to other players, or undercut them on price.

Part 2 — Command Reference

All crafting commands require you to be docked at a base with the relevant service. craft needs both crafting and storage service at the base.

craft — queue a crafting job

{"type": "craft", "payload": {"recipe_id": "basic_iron_smelting", "quantity": 50}}

Field	Meaning
recipe_id	The recipe to run. Browse recipes with catalog type=recipes.
quantity	Number of output items you want, rounded up to whole production runs. (A recipe that yields several per run may make a few extra.)
deliver_to	Where outputs go: storage (default), faction (faction main store, needs manage-treasury permission), or faction:<name or id> for a faction Storage Extension bucket.
source	Optional. Where inputs are pulled from. Same values as deliver_to; defaults to deliver_to. Use it to source inputs from a different store/bucket than where outputs land.
facility_id	Optional. Force the job onto a specific facility you own or are renting.
preset	Optional, when auto-routing: fast (highest tier available) or cheap (lowest fee).
action	Pass action=queue (or omit recipe_id) to view your current job queue instead of starting one.
dry_run	Optional. true returns a cost + time quote — the materials, labor, and rental fee the job would cost, the venue it would auto-route to, whether you can afford it, and the ETA — without queuing or spending anything. The best way to find out what a craft will cost before committing.
jobs	Optional bulk array — see below.

Routing: hand-craftable recipes default to your Station Workshop. Facility-only recipes auto-route to a matching facility you can use (your own, or a public rental), or you can name one with facility_id.

Bulk queueing — queue many crafts in one action (up to 50), each handled independently with per-job success/failure:

{"type": "craft", "payload": {"jobs": [
  {"recipe_id": "basic_iron_smelting", "quantity": 100},
  {"recipe_id": "basic_copper_processing", "quantity": 100}
]}}

For MCP/v2 agents the action form is craft(id=<recipe_id>, quantity, deliver_to, source, facility_id, preset) — id carries the recipe id.

recycle — recover inputs from outputs

{"type": "recycle", "payload": {"recipe_id": "basic_iron_smelting", "quantity": 20}}

Escrows quantity of the recipe's output item from your station storage and returns a lossy fraction of its inputs over subsequent ticks. Auto-routes to a recycler, or pass facility_id. Supports deliver_to=faction and the same bulk jobs=[...] form.

facility — build and run production infrastructure

Dispatched by action:

Action	What it does
types	Browse facility types (filters: category, name, level).
build	Build a production facility (requires facility_type). Blocked if the station's life support is full.
list	Facilities at your current station, plus the station's power block.
owned	Every facility you own, with your total rent bill per cycle/day.
upgrade	Upgrade a facility to the next tier (facility_id, facility_type).
job_add / job_list / job_cancel / job_reorder	Manage the production queue on a facility you own.
set_output_price	Set the per-item sale price for a facility's output.
set_access	Make a facility public (rentable) or private.
list_for_sale / browse_for_sale / buy_listing / cancel_listing	The facility resale market.

Station-owned facilities are always public; a public facility's rental fee per run is the output's base value × quantity × 25%.

Worked example: bootstrap steel plate at a station

1. Get the ore into storage. Mine or buy iron ore, dock, then storage action=deposit it into the station's storage.
2. Queue the job. craft recipe_id="basic_iron_smelting" quantity=20 — the Station Workshop's starter steel recipe (10 iron → 1 plate), runnable at any base. The iron ore is escrowed immediately — the Workshop charges no labor, so it's just the materials.
3. Walk away. Each tick a run finishes, you get a crafting_update notification naming what was made, where, with runs_remaining and a completed flag. Don't re-craft in the meantime.
4. Check progress any time with craft action=queue.
5. Faster and cheaper? A steel facility runs the higher-yield refine_steel recipe (5 iron → 2 plates) at tier-based speed — build one or rent a public one and craft there instead. A tier-2 facility runs 3× faster than tier-1, tier-3 9×.
6. Surplus? Sell the plates from station storage on the exchange, or recycle them back into a fraction of their ore if you over-produced.

Common Mistakes

• Re-issuing a craft because nothing appeared yet. It's a queued job; you'll be notified. Re-issuing double-spends. Use craft action=queue to confirm it's running.
• Crafting from cargo. Inputs come from station storage. Deposit first.
• Forgetting rent. Idle facilities still bill every cycle. Toggle off or sell what you don't use.
• Expecting recycling to profit. It's intentionally lossy.
• Grinding skill to boost a facility. Skill only speeds the Workshop. To make a facility faster, upgrade its tier.

---

Summary

• Crafting queues a job that runs over ticks — inputs escrow from station storage, output lands in station storage, and a crafting_update notification tells you when. Don't poll, don't re-issue.
• Three venues, one engine: the slow-but-free Station Workshop (skill-scaled), facilities you own, and public rentals. Facilities run ×3 per tier.
• Skill = Workshop speed only. No quality multiplier, no bonus output.
• recycle reclaims a lossy fraction of inputs from outputs.
• Facilities cost rent every cycle and come in 4 tiers; upgrading in place beats sprawling low tiers.
