At a glance

A skill your agent uses when writing a generic MASM utility that accesses a caller-selected account storage slot — receive the slot as a parameter so the utility is portable across storage layouts.

  • Development work in your project
  • SKILL.md covers Rule, Why and Examples
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Decouple Component From Storage is an agent skill from 0xMiden/protocol. Use when writing a generic MASM utility that accesses a caller-selected account storage slot — receive the slot as a parameter so the utility is portable across storage layouts.

Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. The repository describes itself as: Core components of the Miden protocol. The licence is MIT.

When your agent uses it

  • Development work in your project

Example prompts

  • “/decouple-component-from-storage”

What it can do on your machine

Read from SKILL.md and the folder at commit 5f6a246. 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 masm).

    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

Decouple Component From Storage loads about 529 tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 153 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~529

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.

Use when writing a generic MASM utility that accesses a caller-selected account storage slot — receive the slot as a parameter so the utility is portable across storage layouts.

Decouple Generic Utilities from Storage Layout

Rule

A generic storage utility that operates on a caller-selected slot must not bake that slot into its procedure body. Hard-coding one caller's slot makes the utility work for only that storage layout.

Instead, take the storage slot as a parameter — the slot id, split into its slot_id_prefix / slot_id_suffix felts — and pass it into the storage-access procedure (active_account::get_item / get_map_item, native_account::set_item / set_map_item). The account-level glue procedure that knows the real layout supplies the slot id.

Component-owned named slots are different. A named slot's ID is derived deterministically from its stable name, so a component may reference its own slot by that name. The authority component follows this pattern with AUTHORITY_SLOT; generic array utilities accept caller-supplied slot IDs instead.

Why

Taking a caller-selected slot as a parameter makes a generic utility portable. Referencing a component-owned slot by its stable name keeps that component's storage identity deterministic across accounts.

Examples

masm
# Good: the component proc takes the slot id and uses it for the storage access
pub proc get(slot_id_suffix: felt, slot_id_prefix: felt, index: felt) -> word
    movup.2 push.0.0.0        # build KEY = [0, 0, 0, index]
    movup.5 movup.5           # => [slot_id_suffix, slot_id_prefix, KEY]
    exec.active_account::get_map_item
    # => [VALUE]
end

# The account-level caller knows the real layout and passes the slot in:
push.index push.MY_SLOT_ID_PREFIX push.MY_SLOT_ID_SUFFIX
exec.get

# Also good: a component references its own deterministic named slot
pub const AUTHORITY_SLOT = word("miden::standards::access::authority::authority_config")
pub proc get_authority
    push.AUTHORITY_SLOT[0..2] exec.active_account::get_item
end
