Grimoire CLI Skill

This skill is the base operating playbook for Grimoire.

When To Use

Use this skill when the task includes:

install/setup of Grimoire tooling

creating or editing .spell files

syntax questions about DSL capability

advisory (advise) authoring, debugging, and replay workflows

setup/compile/validate/simulate/cast/resume workflows

debugging spell compile/runtime failures

Mandatory Loading Rules

All references/ and docs/ paths below are relative to this skill directory (skills/grimoire/). These rules are required — they solve syntax coverage gaps that cause authoring errors.
STOP — read this first: Do NOT search the codebase, grep for syntax patterns, or rely on memory for DSL syntax. The reference files bundled with this skill are the single source of truth. IMMEDIATELY use the Read tool on the files listed below before writing or editing any spell content.

For any .spell authoring/editing task — IMMEDIATELY read these files using the Read tool before doing anything else:

references/syntax-capabilities.md

references/authoring-workflow.md

For CLI flag details — IMMEDIATELY read using the Read tool:

references/cli-quick-reference.md

For any advisory task (advise, advisors, replay) — IMMEDIATELY read using the Read tool:

docs/how-to/use-advisory-decisions.md

docs/explanation/advisory-decision-flow.md

For local fork preview workflows — IMMEDIATELY read using the Read tool:

references/anvil-cheatsheet.md

docs/how-to/simulate-on-anvil-fork.md

For wallet setup and execution key flows — IMMEDIATELY read using the Read tool:

docs/how-to/use-wallet-commands-end-to-end.md

For RPC/signer/transaction diagnostics — IMMEDIATELY read using the Read tool:

Installation Resolution

Select the first working invocation and reuse it for the session.

Global:

npm i -g @grimoirelabs/cli

command prefix: grimoire

No-install:

command prefix: npx -y @grimoirelabs/cli

Repo-local:

command prefix: bun run packages/cli/src/index.ts --

If one path fails, move to the next path automatically.

If grimoire venue doctor ... fails with Unknown venue adapter "doctor", prefer repo-local invocation (bun run packages/cli/src/index.ts) or upgrade global CLI.

When using repo-local Bun execution, always keep the trailing -- so Bun forwards flags to Grimoire instead of consuming them.

Fast Start (Immediate Success Path)

Use this sequence before writing custom spells:

<grimoire-cmd> --help

<grimoire-cmd> setup (guided interactive execute onboarding)

<grimoire-cmd> validate spells/compute-only.spell

<grimoire-cmd> simulate spells/compute-only.spell --chain 1

If all three pass, proceed to spell authoring.

Setup security/runtime expectations:

setup prompts for hidden passwords and never echoes input

blank RPC input falls back to chain default public RPC

setup may write .grimoire/setup.env unless --no-save-password-env is used

CLI auto-loads nearest .grimoire/setup.env at startup without overriding existing env vars

Authoring and Execution Policy

Read syntax references first (mandatory rule above).

Author/update spell.

Run format to canonicalize layout before validation.

Run validate (use --strict for advisory-heavy spells).

Fix errors/warnings and re-run until validation passes.

Run simulate.

Before venue metadata queries or value-moving runs, execute venue doctor for the target adapter/chain.

Example: <grimoire-cmd> venue doctor --adapter uniswap --chain 1 --rpc-url <rpc> --json

Before value-moving runs on EVM venues, verify endpoint and signer state with Foundry Cast quickchecks (chain-id, block-number, balance, nonce).

Do not apply Anvil/Cast checks to offchain venues such as hyperliquid.

For advisory steps intended for deterministic execution, record and then use --advisory-replay <runId> in dry-run/live cast.

If spell includes irreversible actions, require cast --dry-run before any live cast.

Ask for explicit user confirmation before live value-moving cast.

For cross-chain mode, require explicit per-chain RPC mappings:

--rpc-url <sourceChainId>=<url>

--rpc-url <destinationChainId>=<url>

For cross-chain Morpho actions, require explicit market mapping via:

--morpho-market-id <actionRef>=<marketId> (repeatable), or

--morpho-market-map <path>

For Morpho supply-only strategies, prefer vault_deposit / vault_withdraw (explicit vault address).

If vault address is missing, list candidate vaults and require user to pick one; never auto-select.

For Morpho market strategies (borrow/collateral/lend), require explicit market_id and use explicit actions:

morpho_blue.supply_collateral(asset, amount, market_id)

morpho_blue.withdraw_collateral(asset, amount, market_id)

Use bare 0x... address literals in action token fields; quoted address-like strings trigger QUOTED_ADDRESS_LITERAL.

For Morpho doctor readiness checks, set wallet env explicitly (GRIMOIRE_WALLET_ADDRESS preferred, fallback WALLET_ADDRESS).

If a cross-chain run is left waiting, continue with resume <runId> (use --watch to poll settlement).

Never place passwords/private keys in agent prompts or inline command assignments.

Prefer keystore + --password-env over --private-key for dry-run/live casts.

Treat .grimoire/setup.env as plaintext secret material: keep local-only and rotate/remove when no longer needed.

For commands run outside the project tree, set GRIMOIRE_SETUP_ENV_FILE=/abs/path/to/.grimoire/setup.env when needed.

Runtime Behavior Model

One runtime semantics: preview first, commit only for execute paths.

simulate and cast --dry-run are preview-only flows.

Live cast can commit irreversible actions when policy and runtime checks pass.

simulate supports explicit --rpc-url, with precedence: --rpc-url -> RPC_URL_<chainId> -> RPC_URL.

Phase 1 cross-chain execution uses two-spell orchestration (--destination-spell) with one logical run id and resume support.

Use triggers <spell> to discover stable handler ids natively before targeted execution.

simulate and cast support selected-trigger execution via --trigger-id, --trigger-index, and legacy --trigger.

For multi-handler spells, prefer --trigger-id; --trigger is label-based and can be ambiguous.

Cross-chain simulate / cast must forward the same selected trigger into per-chain execution.

In --json mode, parse stdout only; progress and spinner output can still appear on stderr.

Query Functions (price / balance / apy / metric)

Always prefer query functions over advisory for structured data fetching. These are deterministic, fast, and don't require LLM calls.

price(BASE, QUOTE[, SOURCE]) — live token price via query provider (requires Alchemy RPC URL)

balance(ASSET[, ADDRESS]) — on-chain token balance via RPC (any RPC URL)

apy(VENUE, ASSET[, SELECTOR]) — venue-backed APY surface (for example Aave and Morpho)

metric(SURFACE, VENUE[, ASSET[, SELECTOR]]) — generic protocol metric surface

Selector guidance:

market/vault id selector: apy(morpho, USDC, "wbtc-usdc-86")

vault selector (Morpho): metric("vault_net_apy", morpho, USDC, "vault=0xVaultAddress")

Morpho vault_apy / vault_net_apy require explicit selector; do not rely on implicit defaults.

key/value selector: metric("quote_out", uni_v3, USDC, "asset_out=WETH,amount=1000000,fee_tier=3000")

Never use an advisory (advise) just to fetch prices, balances, APYs, or other structured metrics

Use advisory only when the task requires LLM judgment, reasoning, or interpretation.

Advisory Operating Rules

Advisory must be explicit statement form: x = advise advisor: "prompt" { ... }.

Treat advisory outputs as typed contracts; enforce schema with output.

Require timeout and fallback in every advisory block.

Prefer validate --strict when advisory logic gates value-moving actions.

Use replay for determinism when moving from preview/dry-run to live execution.

For runtime debugging, use --advisory-trace-verbose (non-JSON mode) to stream detailed advisory traces.

Venue Metadata and Snapshots

Use venue skills for snapshot parameters and market metadata:

grimoire-aave

grimoire-uniswap

grimoire-morpho-blue

grimoire-hyperliquid

grimoire-pendle

grimoire-polymarket

Formatting policy for venue CLI output:

prefer --format json for automation or nested payloads

use --format table for human-readable summaries
