# Grimoire Aave Skill

Use this skill to query Aave V3 metadata and reserve snapshots for strategy inputs.

Preferred invocations:

- `grimoire venue aave ...`
- `npx -y @grimoirelabs/cli venue aave ...` (no-install)
- `bun run packages/cli/src/index.ts venue aave ...` (repo-local)
- `grimoire-aave ...` (direct binary from `@grimoirelabs/venues`)

Recommended preflight:

- `grimoire venue doctor --adapter aave --chain 1 --rpc-url <rpc> --json`

## Commands

- `grimoire venue aave health` — check Aave protocol health
- `grimoire venue aave chains` — list supported chains
- `grimoire venue aave markets --chain <id> [--user <address>]` — list markets on a chain (optionally with user positions)
- `grimoire venue aave market --chain <id> --address <market> [--user <address>]` — single market details
- `grimoire venue aave reserve --chain <id> --market <address> --token <address>` — single reserve details
- `grimoire venue aave reserves --chain <id> [--market <address>] [--asset <symbol|address>]` — list reserves with optional filters
- `grimoire venue aave reserves-snapshot --chain <id> [--market <address>] [--asset <symbol|address>]` — generate spell `params:` block for reserves (agent-only)

## Examples

```bash
grimoire venue aave health
grimoire venue aave health --format table
grimoire venue aave chains
grimoire venue aave markets --chain 1 --format table
grimoire venue aave market --chain 1 --address 0x87870Bca3F3fD6335C3F4ce8392D69350B4fA4E2
grimoire venue aave reserve --chain 1 --market 0x87870Bca3F3fD6335C3F4ce8392D69350B4fA4E2 --token 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48
grimoire venue aave reserves --chain 1 --asset USDC --format table
grimoire venue aave reserves --chain 1 --asset USDC --format spell
grimoire venue aave reserves-snapshot --chain 1 --asset USDC
```

Use `reserves-snapshot` to emit a `params:` block for spell inputs. This is an agent-only command (output suppressed in interactive mode).

## Supported Chains

| Chain | Market Address |
|-------|---------------|
| Ethereum (1) | `0x87870Bca3F3fD6335C3F4ce8392D69350B4fA4E2` |
| Base (8453) | `0xA238Dd80C259a72e81d7e4664a9801593F98d1c5` |

## Spell Constraints

Aave V3 actions do not currently support runtime constraints (`max_slippage`, `min_output`, etc.). The adapter handles approvals and amount conversion automatically.

```spell
aave_v3.lend(USDC, params.amount)
aave_v3.withdraw(USDC, params.amount)
aave_v3.borrow(USDC, params.amount)
aave_v3.repay(USDC, params.amount)
```

## Metric Surface (Spell Comparisons)

Aave exposes the `apy` metric surface for comparisons:

```spell
aave_apy = apy(aave, USDC)
aave_apy_generic = metric("apy", aave, USDC)
```

Use this in conditional logic (for example, compare against Morpho APY before reallocating).

## Amount Format

The `@aave/client` SDK uses different amount formats per action:

| Action | Format | Example (0.1 USDC) |
|--------|--------|---------------------|
| supply | `value: "0.1"` | Human-readable BigDecimal |
| borrow | `value: "0.1"` | Human-readable BigDecimal |
| withdraw | `value: { exact: "100000" }` | Raw amount in `exact` wrapper |
| repay | `value: { exact: "100000" }` | Raw amount in `exact` wrapper |

The adapter handles this conversion automatically.

## Notes

- Read-only metadata endpoints only.
- Outputs JSON/table; `reserves` also supports `--format spell`.
- Prefer `--format json` in automation; use table for quick interactive checks.
