Create Order

tronsave_create_order

Create a new buy order on the TronSave market. Key inputs: orderResourceType (ENERGY|BANDWIDTH), orderReceiver (TRON base58), orderUnitPrice in SUN (NOT TRX), orderDurationSec, orderResourceAmount, and paymentMethod: (1) onchain — requires a signed payment tx in paymentSignedTx; (2) internal — deducts from internal balance. Side effect: creates a live order matchable by the market. Requires a signature session and mcp-session-id. Always derive orderUnitPrice and paymentPaymentAmount from the latest tronsave_estimate_buy_resource for the same receiver, amount, and duration to avoid reverts. FRESHNESS: re-quote immediately before submitting — estimates older than a few seconds (one TRON block ≈ 3s) may be stale and cause the order to revert or fill at the wrong price.

Input Schema

TableJSON Schema

Name	Required	Description
`orderReceiver`	Yes	TRON base58 address (starts with T) that receives delegated resource. Same as `receiver` passed to `tronsave_estimate_buy_resource`.
`paymentMethod`	Yes	Payment method for this order: `onchain` (wallet signed tx) or `internal` (internal balance).
`orderUnitPrice`	Yes	Unit price in SUN. Prefer aligning with `minResourcePrice` or `buyResourcePrice` from the latest `tronsave_estimate_buy_resource` for the same receiver, amount, and duration.
`paymentSignedTx`	No	Required when `paymentMethod=onchain`. TronWeb-shaped signed TRON transaction (`{ txID, raw_data, raw_data_hex, signature[] }`). Must be produced client-side by the user's wallet; never fabricate or hand-edit.
`orderDurationSec`	Yes	Delegation duration in seconds. Must match the `durationSec` used in `tronsave_estimate_buy_resource`.
`orderResourceType`	Yes	Resource to buy: ENERGY (smart contracts) or BANDWIDTH (transactions). Must match `tronsave_estimate_buy_resource`.
`orderResourceAmount`	Yes	Amount of ENERGY or BANDWIDTH units to purchase. Same as `buyResourceAmount` in estimate when applicable.
`paymentPaymentAmount`	Yes	Payment amount in SUN. Prefer deriving from `tronsave_estimate_buy_resource`; if converting to TRX, divide SUN by `1e6`.

Output Schema

TableJSON Schema

Name	Required	Description
`code`	Yes	GraphQL mutation status code (HTTP-like; `0`/`200` indicates success). Always pair with `success` for routing.
`data`	No
`message`	Yes	Human-readable status text. Populated even on success; localized error messages may appear here on failure.
`success`	Yes	Whether the mutation succeeded at the backend level. Always check this before reading `data`.

TDQS

A4.3/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations indicate readOnlyHint=false, which matches the mutation behavior. The description adds important behavioral context: side effects (creates a live matchable order), required session, and the risk of stale estimates causing reverts or wrong prices. No contradictions with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is well-structured and front-loaded: it starts with the main purpose, then lists key inputs, explains side effects, and provides usage guidance. While it is somewhat lengthy, each sentence adds value. It could be slightly more concise but is still effective.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the complexity (8 parameters, nested objects, multiple payment methods), the description covers preconditions, side effects, and critical constraints. It references the estimate tool for proper parameter derivation. The existence of an output schema reduces the need to explain return values. Overall, it is fairly complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. The description adds significant value by explaining that orderUnitPrice is in SUN (not TRX), describing payment method semantics, and emphasizing the relationship between parameters and the estimate tool. This goes beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Create a new buy order on the TronSave market.' It specifies the verb (create), resource (buy order), and key inputs. This distinguishes it from sibling tools like tronsave_cancel_order or tronsave_estimate_buy_resource.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit guidance on when to use each payment method, the need for a signature session and mcp-session-id, and the critical requirement to derive prices from tronsave_estimate_buy_resource. It also warns about freshness. However, it does not explicitly state when not to use the tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
