  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

When NOT to use

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.

Domain references

Audience	Reference
All — shared architecture (read first)	references/shared.md
Token accounts (SPL-compatible, 165 bytes)	references/token-accounts.md
Mint accounts (borsh-deserialized, metadata)	references/mint-accounts.md
Compressible PDAs (per-program, discriminator check)	references/pdas.md

Account type decision

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
