Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
Vesting schedules with @streamflow/stream

What it does

Stream Creation is an agent skill from streamflow-finance/js-sdk. Use when creating token locks or vesting schedules with @streamflow/stream. Apply when user calls createLock, createVesting, createLockBatch, createVestingBatch, or their builder variants, or when building ICreateLinearStreamData / ICreateMultipleLinearStreamData params for stream creation.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including assets (for example `assets/advanced.md`).

It works with Solana. The repository describes itself as: Web3 Distribution Layer. For Token vesting and Airdrops. The licence is GPL-3.0.

When your agent uses it

Creating token locks
Vesting schedules with @streamflow/stream
Calls createLock
CreateLockBatch

Example prompts

“/stream-creation”

What it can do on your machine

Read from SKILL.md and the folder at commit fb236ff. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Stream Creation loads about 1.2k tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 207 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~77
When it runs · the whole SKILL.md, loaded when a task matches: ~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

name: stream-creation
description: Use when creating token locks or vesting schedules with @streamflow/stream. Apply when user calls createLock, createVesting, createLockBatch, createVestingBatch, or their builder variants, or when building ICreateLinearStreamData / ICreateMultipleLinearStreamData params for stream creation.

Stream Creation

Composable API wrappers over SolanaStreamClient in packages/stream/solana/api/. Pass intent-specific params — lock/vesting defaults are pre-filled and enforced.

Choose the right function

Goal	Function	Returns
Lock tokens until one date	`createLock`	`CreateInstructionResult`
Lock — multiple recipients	`createLockBatch`	`BatchInstructionResult`
Linear vesting	`createVesting` (no `initialAllocation`)	`CreateInstructionResult`
Vesting + upfront release	`createVesting` (with `initialAllocation`)	`BatchInstructionResult`
Vesting — multiple recipients	`createVestingBatch`	`BatchInstructionResult`

import { createLock, createLockBatch, createVesting, createVestingBatch } from "@streamflow/stream/solana/api";
import type { ICreateLockParams, ICreateLockBatchParams, ICreateVestingParams, ICreateVestingBatchParams } from "@streamflow/stream/solana/api";

`createLock`

await createLock(
  {
    recipient: "Wallet...", tokenId: "Mint...",
    amount: new BN(1_000_000_000),  // raw units — MUST be > 1
    unlockDate: 1735689600,          // unix timestamp — used as both start and cliff
    name: "Team Lock",
    transferableByRecipient: false,  // only configurable flag, defaults false
    // partner?, tokenProgramId?
  },
  invoker, env,
);

Hardcoded internals — never set these on input: period=1, cliffAmount=amount-1, amountPerPeriod=BN(1), all cancel/topup/withdrawal flags false. Required for isTokenLock() classification.

`createVesting`

Return type is overloaded: omit initialAllocation → CreateInstructionResult; include it → BatchInstructionResult (2 streams created atomically).

await createVesting(
  {
    recipient, tokenId, name,
    amount: new BN(1_000_000_000_000),
    start: 1700000000,
    period: 86400,                   // release interval in seconds
    duration: 365 * 86400,           // OR endDate — mutually exclusive, never both
    cliffAmount: new BN(0),          // optional, defaults BN(0)
    // amountPerPeriod auto-computed via divCeil if omitted
    cancelableBySender: false,
    automaticWithdrawal: false,      // withdrawalFrequency defaults to period when true
    transferableBySender: false, transferableByRecipient: false,
    // initialAllocation: { amount: BN(...) }  ← changes return type to BatchInstructionResult
  },
  invoker, env,
);

Duration rules: exactly one of duration / endDate; must be positive; must be >= period.

amountPerPeriod auto-compute (divCeil):

remaining  = amount - cliffAmount
periods    = floor(duration / period)
result     = ceil(remaining / periods)

Classification gotcha: cliffAmount close to amount (within 1) causes the stream to classify as Lock, not Vesting.

`createLockBatch` / `createVestingBatch`

Per-recipient amount and name; shared config at top level.

await createLockBatch(
  { tokenId, unlockDate, recipients: [{ recipient, amount, name }] },
  invoker, env,
);

await createVestingBatch(
  { tokenId, start, period, duration,  // OR endDate
    recipients: [{ recipient, amount, name, cliffAmount?, amountPerPeriod? }] },
  invoker, env,
);

Lock batch: each recipient auto-gets cliffAmount = r.amount - 1, amountPerPeriod = BN(1)
Vesting batch: amountPerPeriod computed independently per recipient; explicit r.amountPerPeriod skips auto-compute
Batch vesting does not support initialAllocation

Builder variants (params only, no execution)

Use when you need the raw params object to inspect or compose with other instructions:

import { buildLockParams, buildVestingParams, buildLockBatchParams, buildVestingBatchParams, resolveDuration, computeAmountPerPeriod } from "@streamflow/stream/solana/api";

const data: ICreateLinearStreamData = buildLockParams({ ... });
const data: ICreateLinearStreamData = buildVestingParams({ ... });
const data: ICreateMultipleLinearStreamData = buildLockBatchParams({ ... });
const data: ICreateMultipleLinearStreamData = buildVestingBatchParams({ ... });

Source: packages/stream/solana/api/create-lock.ts, create-vesting.ts, create-lock-batch.ts, create-vesting-batch.ts

Advanced: protocol-level patterns

Why the defaults are what they are, isTokenLock() classification criteria, initial allocation internals, and dynamic/price-triggered stream differences: assets/advanced.md

Can I use Stream Creation in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add streamflow-finance/js-sdk --skill stream-creation -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/stream-creation, .gemini/skills/stream-creation, .github/skills/stream-creation and .opencode/skills/stream-creation in your project.

What does Stream Creation need to run?

SKILL.md names no scripts, command-line tools or credentials: Stream Creation is instructions for the agent only.
