Workflow

工作流程

Clarify intent
- Recommend plan mode, if it's not activated
- Use
```
AskUserQuestion
```
  to resolve blind spots
- All questions must be resolved before execution
Identify references and skills
- Match task to domain references below
- Locate relevant documentation and examples
Write plan file (YAML task format)
- Use
```
AskUserQuestion
```
  for anything unclear — never guess or assume
- Identify blockers: permissions, dependencies, unknowns
- Plan must be complete before execution begins
Execute
- Use
```
Task
```
  tool with subagents for parallel research
- Subagents load skills via

明确意图
- 若计划模式未激活，推荐启用该模式
- 使用
```
AskUserQuestion
```
  工具解决信息盲点
- 所有问题必须在执行前解决
识别参考资料与技能
- 将任务与下方的领域参考资料进行匹配
- 查找相关文档与示例
编写计划文件（YAML任务格式）
- 任何不清楚的内容都使用
```
AskUserQuestion
```
  工具询问——切勿猜测或假设
- 识别阻碍因素：权限、依赖项、未知内容
- 计划必须完整后才能开始执行
执行任务
- 使用
```
Task

When NOT to use

不适用场景

For simple account lookups, call

get_account_interface

from

light-client

. It races hot and cold lookups automatically.

This skill is for continuous data pipelines: aggregators, market makers, and indexers that need real-time state change notifications rather than point queries.

对于简单的账户查询，调用

light-client

中的

get_account_interface

即可，它会自动并行执行冷热查询。

本技能适用于持续数据管道场景：需要实时状态变更通知而非单点查询的聚合器、做市商和索引器。

Account type decision

账户类型选择

Streaming...	Account type	Key difference
SPL-compatible token balances	Token accounts	`PodAccount` parsing, 165-byte layout
Mint supply, metadata, authorities	Mint accounts	`Mint::deserialize` , borsh layout
Your program's PDA state	Compressible PDAs	8-byte discriminator check, per-program filter
