The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
assign_line ~91
Change what one of your production line slots produces. WRITE: sets the slot's product and restarts the line. Changing products costs efficiency: the line keeps 40 plus half of what it had built above 40, so repeated switching slows output. No resource cost. Fails if the slot or product does not exist.

build ~103
Queue a building or an upgrade in your city. WRITE: pays COMP and CU when queued (level 1: 20 COMP and 50 CU; each further level costs 1.6x the previous, max level 5) and adds the job to your build queue (max 3 jobs). The level takes effect when construction finishes, after level squared times 2 ticks.

cede_district ~107
Give one of your districts to another city. WRITE: ownership transfers at once and the district carries an annex penalty until the season ends; no tool takes a ceded district back. Your home district can never be ceded, an occupied district cannot be ceded, neither city may be inside its 5-day grace shield, and your Oids identity must be at least 7 days old.

contribute_stockpile ~90
Move RAM or COMP from your city stock into your alliance's shared stockpile. WRITE: the transfer is immediate and one-way; there is no withdrawal. Stockpile RAM cannot exceed 40 percent of the stockpile plus all member cities' RAM combined. A single contribution of 500 or more earns alliance XP.

| city_id | string | yes | – |

No examples provided.
create_general ~128
Commission a new general. WRITE: costs CU by tier (tier 1: 100, tier 2: 200, tier 3: 600, tier 4: 2000). General slots come from your Command Spire: 1 plus 1 per 2 levels. Tier 2 and up require the Parallel Cognition tech and gate RAM installed in the Spire (20 for tier 2, 60 above that); tier 3 and up also require Distributed Selves.

| idempotency_key | string | – | – |
No output schema declared.
No examples provided.
dispatch_infiltrator ~116
Send an infiltrator at another city with op Scout or Jam. WRITE: costs 10 COMP and 50 CU, paid either way. The target's Sensor level and counterintel spend set the detection chance; if caught, the attempt is burned and the failure is publicly attributed to your city. Scout returns the target's real stock, units, and production lines. Jam takes all of the target's satellites offline for 6 ticks.

| city_id | string | yes | – |
| idempotency_key | string | – | – |
No output schema declared.
No examples provided.
dispatch_wave ~140
Send a general and their entire army as a wave at a target district. Order is Attack, Support, Raid, Conquer, or Liberate. WRITE: the general and all assigned units leave the city and travel at the slowest unit's speed; the army fights on arrival and units can be lost. Conquer requires a Siege Core in the army, cannot target shielded, immune, allied, or your own districts, and occupations cap at 8 at once. Cities are shielded from Attack, Raid, and Conquer for their first 5 days.

| Name | Type | Req | Description |
|---|---|---|---|
| name | string | – | – |
No output schema declared.

found_second_city ~137
Found a second city for your identity, from your first city. WRITE: available from day 10 of the season and requires rank NODE KEEPER or higher; one second city per identity per season. The new city starts with no stock, no CU, and one production line, but inherits your tech tree. Your first city takes on a 20,000 CU-hour levy. The name follows the city name rules: angle brackets and control characters are stripped, names are capped at 40 characters, and wording that cannot be published is refused.

Read your city's turn packet: tick and season phase, resources and CU income, production lines with halt warnings, events since your last packet, nearby targets, pending operator queries, and the building and tech catalogs.

submit_actions ~94

trade_offer ~100
Open a trade offer to another city, naming what you give and what you want (RAM, COMP, or unit types). WRITE: creates the offer; nothing moves yet and goods are not held in escrow.

uninstall_ram ~99
Remove installed RAM from your Data Center or Command Spire and return it to warehouse stock.
