Skill: richard7463/xlayer-execution-guard (version 1.0.1)

--- name: xlayer-execution-guard description: "Run an executable X Layer pre-execution guard for autonomous agents: OnchainOS DEX route judgment, honeypot and price-impact checks, proof-mode evidence, and optional Agentic Wallet execution via onchainos. Use when OpenClaw/Codex needs to test, block, resize, or execute an X Layer swap intent with judge-ready proof." --- # X Layer Execution Guard Use this skill to turn an agent swap intent into a guarded execution decision and proof artifact. The installed skill includes its own Python runtime in `runtime/` and two scripts in `scripts/`: - `scripts/run_execution_guard.py` runs the guard CLI. - `scripts/check_agentic_wallet.py` checks whether `onchainos` and Agentic Wallet are reachable. ## Operating Rules 1. Default to `--no-execute` or `--execution-mode proof` while evaluating a request. 2. Only use `--live` or `--execution-mode agentic-wallet` after explicit user approval for a real wallet action. 3. Treat `proof` mode as simulated execution evidence. Only `agentic-wallet` mode can return a real transaction hash. 4. If OnchainOS API credentials are missing, the runtime returns a mock install-smoke result. Do not present mock output as live proof. 5. For live X Layer runs, use chain `196` unless the user explicitly chooses another chain. ## OpenClaw Quick Start Set the skill directory first. In OpenClaw it is usually: ```bash SKILL_DIR="$HOME/.openclaw/skills/xlayer-execution-guard" ``` If installed into a local workdir with ClawHub, use: ```bash SKILL_DIR="$PWD/skills/xlayer-execution-guard" ``` Install the only runtime dependency if needed: ```bash python3 -m pip install --user -r "$SKILL_DIR/requirements.txt" ``` Check the Agentic Wallet environment: ```bash python3 "$SKILL_DIR/scripts/check_agentic_wallet.py" ``` Run a safe pre-execution judgment: ```bash PYTHONPATH="$SKILL_DIR/runtime" python3 "$SKILL_DIR/scripts/run_execution_guard.py" \ --agent strategy-office \ --intent-id strategy-office-round-001 \ --from USDC \ --to USDT \ --amount 10 \ --amount-mode readable \ --slippage 0.5 \ --max-impact 1.20 \ --no-execute \ --output guard-proof.json ``` Run proof-mode closed-loop evidence without touching the wallet: ```bash PYTHONPATH="$SKILL_DIR/runtime" python3 "$SKILL_DIR/scripts/run_execution_guard.py" \ --agent strategy-office \ --intent-id strategy-office-proof-001 \ --from USDC \ --to USDT \ --amount 10 \ --amount-mode readable \ --execution-mode proof \ --output guard-proof.json ``` Run a live Agentic Wallet execution only after user approval: ```bash PYTHONPATH="$SKILL_DIR/runtime" python3 "$SKILL_DIR/scripts/run_execution_guard.py" \ --agent strategy-office \ --intent-id strategy-office-live-001 \ --from USDC \ --to USDT \ --amount 10 \ --amount-mode readable \ --slippage 0.5 \ --execution-mode agentic-wallet \ --wallet default \ --chain 196 \ --output guard-live-proof.json ``` `--live` is an alias for `--execution-mode agentic-wallet`. ## Required Environment For real OnchainOS route judgment, export API credentials in the OpenClaw environment or `~/.config/onchainos.env`: ```bash export ONCHAINOS_API_KEY="..." export ONCHAINOS_API_SECRET="..." export ONCHAINOS_API_PASSPHRASE="..." export ONCHAINOS_CHAIN_INDEX="196" ``` For live wallet execution, `onchainos` must be installed and logged in: ```bash onchainos wallet login onchainos wallet status ``` ## What The Guard Checks The runtime uses OnchainOS DEX Aggregator APIs for: - token discovery through [REDACTED_SECRET] - liquidity source discovery through [REDACTED_SECRET] - aggregated and per-DEX quote comparison through `/api/v6/dex/aggregator/quote` The output includes: - `pre_execution.verdict`: `execute`, `resize`, `retry`, or `block` - `pre_execution.checks`: quote availability, price impact, fallback coverage, token tax, honeypot flags, gas and fee fields - `execution.status`: `simulated_success`, `success`, `broadcasted`, `failed`, or `not_executed` - `post_execution.proof_id` and `moltbook_summary` - `closed_loop_validation`: whether the pre-execution verdict matched the post-execution outcome ## Failure Handling - Missing API credentials: output is mock mode and suitable only for install verification. - `wallet_ready=false`: run `onchainos wallet login` in the same OpenClaw environment. - `verdict=block`: do not execute; show the block reason. - `verdict=resize`: execute only if the user accepts the resized risk outcome. - Live execution returns no tx hash: preserve the full JSON output and inspect `execution.error`.
