+### Merkl
+
+Browse incentivized DeFi opportunities, check unclaimed rewards, and claim Merkl rewards across 50+ chains. Merkl is a reward distribution layer — it incentivizes positions on other protocols like Aave, SparkLend, Morpho, and more.

 The `*_get_opportunities` tools return the top 10 reserves per network by default, with slim fields to minimize token usage. Optional parameters:
 
 - `token` — filter by token symbol (e.g. `USDC`) or contract address (case-insensitive)
 - `limit` — max reserves per network (default: 10)
 - `detailed` — include all fields like `availableLiquidity`, `liquidationThreshold`, `canBeCollateral` (default: false)
 
+The `merkl` tool uses subcommands: `get_opportunities`, `check_rewards`, `claim_rewards`.

 ## Claude Code Plugin
 
 This project is packaged as a [Claude Code plugin](https://code.claude.com/docs/en/plugins). Install it to get:
 
 - **`/agentic-defi:aave` slash command** — Run Aave operations directly (supply, borrow, repay, withdraw, position, opportunities, permissions)
 - **`/agentic-defi:spark` slash command** — Run SparkLend operations directly (supply, borrow, repay, withdraw, position, opportunities, permissions)
+- **`/agentic-defi:merkl` slash command** — Browse Merkl opportunities, check and claim rewards
 - **SessionStart hook** — Automatically checks that the agentic-wallet MCP server is configured when a session starts

+
+You are executing a Merkl operation. First, invoke the `agentic-defi:merkl-agentic-wallet` skill to load the full protocol context.
+
+Parse the following arguments: $ARGUMENTS
+
+## Subcommands
+
+| Subcommand | Required flags |
+|------------|---------------|
+| `opportunities` | none (optional: `--chain-id`, `--protocol`, `--token`) |
+| `check-rewards` | `--wallet` (optional: `--chain-id`) |
+| `claim-rewards` | `--wallet --chain-id` (optional: `--token`) |
+
+## Instructions
+
+1. If `$ARGUMENTS` is empty, show usage help listing all subcommands above.
+2. Extract the subcommand (first word) and flags from `$ARGUMENTS`.
+3. If any required flags are missing, ask the user for them.
+4. Run the script using: `node ${CLAUDE_PLUGIN_DATA}/dist/skills/merkl-agentic-wallet/merkl.js <subcommand> <flags>`
+5. Follow the SKILL.md workflow for any MCP tool calls (`execute_tx`, `grant_permissions`).
