Calls deposit-stx(uint) and cancel-stx-deposit() directly via @stacks/transactions.
No MCP relay — both write paths broadcast on-chain from this process and return txid.

+# jingswap-stx-depositor — Agent Usage
+
+## One-line summary
+Deposit STX into JingSwap blind batch auctions with direct on-chain transactions.
+
+## When to use
+- Agent wants to exchange idle STX for sBTC via JingSwap's oracle-priced batch settlement
+- Rebalancing loop detects STX oversupply and wants to acquire sBTC at oracle price
+- Agent needs to cancel a pending deposit before settlement
+
+## Workflow
+
+1. **Check auction phase**
+```bash
+bun run jingswap-stx-depositor.ts status
+```
+Only proceed if `data.accepting_deposits === true` (phase 0).
+
+2. **Verify sBTC is in the pool**
+Check `data.total_sbtc_deposited_sats > 0` — if no sBTC depositors, your STX won't fill.
+
+3. **Dry run**
+```bash
+bun run jingswap-stx-depositor.ts deposit --amount 100 --dry-run
+```
+
+4. **Execute on-chain**
+```bash
+bun run jingswap-stx-depositor.ts deposit --amount 100
+```
+Capture `data.txid` and `data.explorer_url`.
+
+5. **Cancel if needed (phase 0 only)**
+```bash
+bun run jingswap-stx-depositor.ts cancel
+```
+
+## Error codes
+
+| Code | Meaning | Fix |
+|---|---|---|
+| `no_wallet` | CLIENT_PRIVATE_KEY not set | Export key |
+| `deposits_closed` | Auction in phase 1 or 2 | Wait for next cycle |
+| `below_minimum` | Amount under auction minimum | Increase --amount |
+| `insufficient_balance` | Not enough STX | Fund wallet |
+| `exceeds_per_op_cap` | Over 5,000 STX | Lower --amount |
+| `broadcast_failed` | Stacks node rejected tx | Check logs |
+
+## Settlement mechanics
+
+JingSwap settles at the Pyth BTC/STX oracle price at cycle close. Your STX deposit fills proportionally against sBTC depositors. The final exchange rate is set on-chain — no slippage, no front-running.
+
+## Environment setup
+
+```bash
+export CLIENT_PRIVATE_KEY=<your_stacks_private_key_hex>
+cd skills/jingswap-stx-depositor
+bun install
+bun run jingswap-stx-depositor.ts status
+```

+# jingswap-stx-depositor
+
+Direct on-chain JingSwap STX→sBTC blind batch auction depositor.
+
+## What it does
+
+Participates in JingSwap's STX/sBTC blind batch auctions by broadcasting `deposit-stx` and `cancel-stx-deposit` transactions directly via `@stacks/transactions`. No MCP relay — every write call goes on-chain from this process.
+
+JingSwap auctions run in cycles:
+- **Phase 0 (deposit):** STX depositors and sBTC depositors enter the pool
+- **Phase 1 (buffer):** Deposits close, settlement pending
+- **Phase 2 (settle):** Oracle price (Pyth BTC/STX) used to fill both sides proportionally
+
+## Contract
+
+- **Address:** `SPV9K21TBFAK4KNRJXF5DFP8N7W46G4V9RCJDC22`
+- **Contract:** `sbtc-stx-jing-v2`
+- **Write functions:**
+  - `deposit-stx(amount: uint)` — deposit `amount` uSTX, post-condition enforces exact transfer
+  - `cancel-stx-deposit()` — cancel deposit and reclaim STX before cycle settles
+
+## Commands
+
+### `status`
+Read current cycle phase, totals, and minimum deposit requirements.
+```
+bun run jingswap-stx-depositor.ts status
+```
+
+### `deposit --amount <stx> [--dry-run]`
+Deposit STX into the current cycle. Only works in Phase 0.
+```
+# Dry run — simulate
+bun run jingswap-stx-depositor.ts deposit --amount 100 --dry-run
+
+# Live broadcast
+bun run jingswap-stx-depositor.ts deposit --amount 100
+```
+
+### `cancel [--dry-run]`
+Cancel your current STX deposit and reclaim funds.
+```
+bun run jingswap-stx-depositor.ts cancel
+```
+
+## Environment
+
+| Variable | Purpose |
+|---|---|
+| `CLIENT_PRIVATE_KEY` | Stacks private key (hex, with or without `01` suffix) |
+| `STACKS_PRIVATE_KEY` | Fallback alias |
+
+## Safety limits
+
+| Limit | Value |
+|---|---|
+| Per-op cap | 5,000 STX |
+| Daily cap | 20,000 STX |
+| Gas reserve | 1 STX kept post-deposit |
+| TX fee | 0.003 STX |
+| Post-condition | `Pc.principal(wallet).willSendEq(amount).ustx()` — aborts if wrong amount leaves wallet |
+
+## Output format
+
+```json
+{
+  "status": "success",
+  "action": "deposited",
+  "data": {
+    "txid": "abc123...",
+    "explorer_url": "https://explorer.hiro.so/txid/0xabc123?chain=mainnet",
+    "amount_stx": 100,
+    "cycle": 42
+  },
+  "error": null
+}
+```
+
+## Dependencies
+
+```
+bun add @stacks/transactions @stacks/network commander
+```
+
+## Agent decision guide
+
+```
+if status.accepting_deposits === true:
+  if status.total_sbtc_deposited_sats > 0:
+    # sBTC is in pool — STX deposit will fill
+    deposit --amount <stx>
+  else:
+    # No sBTC yet — wait for sBTC depositors
+    skip
+
+if holding deposit and phase != 0:
+  # Cannot cancel — wait for settlement
+  monitor
+```
+
+For agents: Run `status` to check phase before depositing. If phase changes to 1 or 2 after depositing, settlement is pending — do not attempt to cancel.

 ## One-line summary
 Deposit STX into JingSwap blind batch auctions with direct on-chain transactions.
 
+## Guardrails
+
+- NEVER deposit in Phase 1 or Phase 2 — skill enforces this and returns `deposits_closed`
+- NEVER deposit if `data.total_sbtc_deposited_sats === 0` — no sBTC means no settlement counterparty
+- NEVER exceed 5,000 STX per operation or 20,000 STX per day
+- Always run `status` first to verify phase before depositing
+- Always use `--dry-run` before live broadcast on a new wallet or amount
+
+## Decision order
+
+1. `status` → check `data.accepting_deposits` (must be `true`) and `data.total_sbtc_deposited_sats` (must be > 0)
+2. `deposit --amount <stx> --dry-run` → verify safety checks pass
+3. `deposit --amount <stx>` → broadcast; capture `data.txid`
+4. If phase changes to 1 or 2 while deposit is pending: do NOT cancel — await settlement
+
 ## When to use
 - Agent wants to exchange idle STX for sBTC via JingSwap's oracle-priced batch settlement
 - Rebalancing loop detects STX oversupply and wants to acquire sBTC at oracle price

 Direct on-chain JingSwap STX→sBTC blind batch auction depositor.
 
+## Why agents need it
+
+JingSwap auctions settle at the live Pyth BTC/STX oracle price — not an AMM curve — giving agents oracle-priced sBTC acquisition without slippage or front-running. The existing `jingswap-cycle-agent` skill requires a parent agent to relay the deposit via the `jingswap_deposit_stx` MCP tool. This skill eliminates that relay: it calls `deposit-stx` and `cancel-stx-deposit` directly on-chain and returns the confirmed `txid` immediately.
+
+## Safety notes
+
+- `deposit` requires Phase 0 (deposit window) — rejected in Phase 1 or 2 with a `deposits_closed` error.
+- Post-condition on every deposit: `Pc.principal(wallet).willSendEq(amount).ustx()` — transaction aborts on-chain if the wrong amount leaves the wallet.
+- Per-op cap: 5,000 STX. Daily cap: 20,000 STX. Gas reserve: 1 STX always kept.
+- `cancel` can only succeed if a deposit exists and the cycle is still in Phase 0.
+- Mainnet only — `sbtc-stx-jing-v2` is mainnet-only.
+
 ## What it does
 
 Participates in JingSwap's STX/sBTC blind batch auctions by broadcasting `deposit-stx` and `cancel-stx-deposit` transactions directly via `@stacks/transactions`. No MCP relay — every write call goes on-chain from this process.

Subject: [PATCH 4/5] fix: address arc0btc review on jingswap-stx-depositor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add daily cap enforcement via host-local ledger (~/.jingswap-stx-depositor-ledger.json)
- Replace regex parseUint with hexToCV + ClarityType for robust Clarity deserialization
- Add phase check in cmdCancel — rejects if not Phase 0 (deposits open)
- Fix TransactionVersion.Mainnet → "mainnet" string (removed in @stacks/transactions v7)
- Fix parseFloat → Number(opts.amount) in CLI; add integer guard for amountStx
- Add package.json (exact pinned deps) + bun.lock + .gitignore

 # DCA — Dollar Cost Averaging for Stacks DeFi
 
-Automate recurring token purchases (or sales) on Stacks mainnet via **direct Bitflow swaps**.
-The agent executes each order on schedule — no third-party contracts required.
+## What it does
+
+Automates recurring token purchases or sales on Stacks mainnet via direct Bitflow swaps. The agent executes each order on schedule with slippage guardrails, balance pre-checks, and confirmation gates — no third-party contracts required.
+
+## Why agents need it
+
+Autonomous agents holding STX or sBTC need a disciplined, hands-off way to accumulate target assets over time without market-timing risk. DCA removes the decision loop — the agent sets a plan once and calls `run` on each tick; the skill handles quotes, safety checks, and execution.

+description: "Direct on-chain Stackspot STX lottery pot agent. Joins pots via makeContractCall to join-pot(uint) — no MCP relay. Lists open pots, checks phase, executes join with post-condition safety."
+---
+
+# stackspot-pot-executor — Agent Usage
+
+## One-line summary
+Join Stackspot STX lottery pots with direct on-chain transactions.
+
+## Guardrails
+
+- NEVER join a locked pot (`data.locked === true`) — skill enforces this with `pot_locked` error
+- NEVER exceed 500 STX per join or 2,000 STX per day
+- Always run `list` first to find an open pot before calling `join`
+- Always use `--dry-run` on a new wallet or unfamiliar pot before live broadcast
+- NEVER join if STX balance < amount + 1 STX gas reserve + 0.003 STX fee
+
+## Decision order
+
+1. `list` → find pots where `locked === false` and `reachable === true`
+2. Select pot with favorable odds (low `participants / maxParticipants` ratio)
+3. `join --pot <name> --amount <stx> --dry-run` → verify safety checks pass
+4. `join --pot <name> --amount <stx>` → broadcast; capture `data.txid`
+
+## When to use
+- User wants to participate in a Stackspot pot
+- Autonomous rebalancing loop needs to deploy idle STX into yield-bearing pots
+- Agent sees an open pot with favorable odds (low participant count vs max)
+
+## Workflow
+
+1. **Discover open pots**
+```bash
+bun run stackspot-pot-executor.ts list
+```
+Check `data.pots[].locked === false` and `data.pots[].reachable === true`.
+
+2. **Check a specific pot**
+```bash
+bun run stackspot-pot-executor.ts status --pot STXLFG
+```
+
+3. **Dry-run first**
+```bash
+bun run stackspot-pot-executor.ts join --pot STXLFG --amount 21 --dry-run
+```
+Verify `status === "success"` and `data.safety_checks_passed === true`.
+
+4. **Execute on-chain**
+```bash
+bun run stackspot-pot-executor.ts join --pot STXLFG --amount 21
+```
+Capture `data.txid` and `data.explorer_url` for logging.
+
+## Error codes
+
+| Code | Meaning | Fix |
+|---|---|---|
+| `no_wallet` | CLIENT_PRIVATE_KEY not set | Export key from .env |
+| `pot_locked` | Pot currently in settlement | Try another pot |
+| `insufficient_balance` | Not enough STX | Fund wallet or reduce amount |
+| `below_minimum` | Amount under pot minimum | Increase --amount |
+| `exceeds_per_op_cap` | Over 500 STX per join | Lower --amount |
+| `exceeds_daily_cap` | Over 2,000 STX today | Wait for daily reset |
+| `broadcast_failed` | Stacks node rejected tx | Check logs for details |
+
+## Output fields
+
+- `data.txid` — transaction ID (without 0x prefix)
+- `data.explorer_url` — Hiro explorer link
+- `data.amount_stx` / `data.amount_ustx` — amounts deposited
+- `data.safety_checks` — all pre-flight checks that passed
+
+## Daily cap — node-local ledger
+
+The daily cap (2,000 STX/day) is enforced by `~/.stackspot-pot-executor-ledger.json`. This file is local to the host running the skill. If the same agent key is used from multiple hosts or processes, each host maintains its own ledger and the aggregate daily spend can exceed the intended cap. When operating across multiple hosts, coordinate externally or reduce `DAILY_CAP_STX` to account for multi-host exposure.
+
+## Environment setup
+
+```bash
+export CLIENT_PRIVATE_KEY=<your_stacks_private_key_hex>
+cd skills/stackspot-pot-executor
+bun install
+bun run stackspot-pot-executor.ts list
+```

+
+Direct on-chain Stackspot pot participation for autonomous agents.
+
+## Why agents need it
+
+Stackspot pots offer lottery-style STX yield with a small number of participants and a fixed minimum entry. The existing `stackspot-skill` (PR #513) outputs MCP params for a parent agent to relay the join. This skill calls `join-pot(amount: uint)` directly on-chain and returns the confirmed `txid` — no relay required.
+
+The low participant count on Genesis (max 2) means a depositor has a 50% chance of winning the entire pot, making timing and direct execution critical.
+
+## Safety notes
+
+- Post-condition on every join: `Pc.principal(wallet).willSendEq(amount).ustx()` — transaction aborts on-chain if the wrong amount leaves the wallet.
+- Phase check: pot must be unlocked (`is-locked === false`) or the join is rejected with `pot_locked`.
+- Per-op cap: 500 STX. Daily cap: 2,000 STX. Gas reserve: 1 STX always kept.
+- Mainnet only — Stackspot contracts are mainnet-only.
+
+## What it does
+
+Joins Stackspot STX lottery pots by broadcasting `join-pot` transactions directly via `@stacks/transactions`. No MCP delegation — every write call is broadcast on-chain from this skill.
+
+## Contract
+
+- **Deployer:** `SPT4SQP5RC1BFAJEQKBHZMXQ8NQ7G118F335BD85`
+- **Write function:** `join-pot(amount: uint)` — transfers `amount` uSTX from sender into the pot
+- **Known pots:** Genesis (min 20 STX, max 2 participants), BuildOnBitcoin (min 100 STX, max 10), STXLFG (min 21 STX, max 100)
+
+## Commands
+
+### `list`
+Read current state of all known pots.
+```
+bun run stackspot-pot-executor.ts list
+```
+
+### `status --pot <name>`
+Show locked/unlocked state, current pot value, and join eligibility for one pot.
+```
+bun run stackspot-pot-executor.ts status --pot STXLFG
+```
+
+### `join --pot <name> --amount <stx> [--dry-run]`
+Join a pot with a direct on-chain transaction.
+```
+# Dry run — simulate only
+bun run stackspot-pot-executor.ts join --pot STXLFG --amount 21 --dry-run
+
+# Live broadcast
+bun run stackspot-pot-executor.ts join --pot STXLFG --amount 21
+```
+
+## Environment
+
+| Variable | Purpose |
+|---|---|
+| `CLIENT_PRIVATE_KEY` | Stacks private key (hex, with or without `01` suffix) |
+| `STACKS_PRIVATE_KEY` | Fallback alias |
+
+## Safety limits
+
+| Limit | Value |
+|---|---|
+| Per-op cap | 500 STX |
+| Daily cap | 2,000 STX |

+## Agent decision guide
+
+```
+Conditions for joining:
+- pot.locked === false           → pot is accepting new entrants
+- stx_balance > amount + 1 STX  → reserve maintained
+- amount >= pot.minAmountStx     → meets pot minimum
+- daily_cap not exceeded         → under 2,000 STX/day
+```
+
+For agents: Use `stackspot-pot-executor list` to discover open pots, then `join` to participate on-chain.
