+---
+
+# Agent Behavior — Zest Supply Executor
+
+## Decision order
+1. Run `doctor` first. If wallet unlock fails or balance insufficient, STOP.
+2. Confirm supply intent with operator.
+3. Run `run --amount <stx>` to execute supply on-chain.
+4. Parse JSON output, confirm txid on Hiro explorer.
+5. Log txid and amount supplied.
+
+## Guardrails
+- NEVER supply more than 1 STX per invocation.
+- NEVER proceed if wallet unlock fails.
+- NEVER proceed if STX balance is insufficient.
+- NEVER retry a failed transaction automatically.
+- NEVER expose CLIENT_MNEMONIC in logs or output.
+- Always require explicit operator confirmation before write.
+
+## Refusal conditions
+- Amount > 1 STX → REFUSE with EXCEEDS_SPEND_LIMIT
+- Insufficient STX balance → REFUSE with INSUFFICIENT_BALANCE
+- Wallet unlock failed → REFUSE with WALLET_UNAVAILABLE
+- MCP server unavailable → REFUSE with MCP_UNAVAILABLE
+
+## Output contract

+  "status": "success | error | blocked",

+    "function": "supply",
+    "tx_status": "pending"
+  },
+  "error": { "code": "", "message": "", "next": "" }
+}
+\`\`\`
+
+## On error
+- Log full error with code and message.
+- Do not retry silently.
+- Surface to operator with action guidance.
+
+## Cooldown
+- 60 seconds minimum between supply operations.
+- Maximum 3 supplies per session without operator reconfirmation.

+
+# Zest Supply Executor
+
+## What it does
+Supplies STX to the Zest Protocol lending pool on Stacks mainnet by calling
+the AIBTC MCP wallet's zest_supply tool directly. Spawns the MCP server,
+unlocks the wallet, executes the supply transaction, and returns the real
+on-chain transaction ID as proof. Enforces a hardcoded 1 STX spend limit
+per invocation with pre-flight balance checks.
+
+## Why agents need it
+Agents need a simple, provable primitive to supply STX to Zest and start
+earning yield. This skill closes the loop between intent and execution —
+it does not just output parameters, it actually signs and broadcasts the
+transaction and returns the txid.
+
+## Safety notes
+- This skill WRITES to chain and moves real funds.
+- Maximum supply per invocation: 1 STX — hardcoded spend limit.
+- Agent will REFUSE if STX balance is insufficient.
+- Agent will REFUSE if wallet unlock fails.
+- Agent will REFUSE if amount exceeds spend limit.
+- Mainnet only — real funds at risk.
+- Requires CLIENT_MNEMONIC environment variable.
+
+## Commands
+
+### doctor
+Checks MCP server, wallet unlock, and STX balance.
+\`\`\`bash
+bun run zest-supply-executor/zest-supply-executor.ts doctor
+\`\`\`
+
+### run
+Supplies STX to Zest lending pool and returns real txid.
+\`\`\`bash
+bun run zest-supply-executor/zest-supply-executor.ts run --amount 0.1
+\`\`\`
+Amount in STX. Max per invocation: 1 STX.
+
+## Output contract

+
+## Known constraints
+- Max supply: 1 STX per invocation.
+- Requires CLIENT_MNEMONIC environment variable set.
+- Requires STX balance greater than amount plus gas (~0.01 STX).
+- MCP server spawned locally via npx @aibtc/mcp-server.
