Add Energy & Bandwidth Manager skill

[M2M-TRC8004-Registry]

Summary

• Adds energy-bandwidth-skill for monitoring and managing TRON Energy and Bandwidth resources
• Check current resource status and usage
• Estimate energy/bandwidth costs for transactions
• Stake TRX for resources, unstake when no longer needed
• Delegate resources to other accounts

Scripts

Great concept! Automatically managing Energy and Bandwidth can effectively reduce long-term TRX burn costs, and we’ve been looking for a best practice like this.

This PR is on our high-priority watch list. Once the underlying asynchronous call mechanics are finalized, we will look into merging it.

To improve it further, could you add a "Safe Guard" configuration? For instance, defining a minimum required TRX balance (e.g., the account must always retain at least 50 TRX for basic fees and cannot stake its entire balance). This ensures the agent doesn't accidentally brick the account due to a flawed strategy.

Updated to address review feedback:

• Safe Guard config: Added safeguard.min_reserve_trx (default 50 TRX) in resource_config.json
• Reserve enforcement: checkReserve() in utils.js blocks stake.js and delegate.js from dropping below the minimum balance
• Async patterns: All scripts use async/await with proper error handling; status.js uses Promise.all() for parallel calls
• Clear error messaging when reserve would be violated

Thanks for the update. I re-checked the latest head after your comment.

I still see two unresolved issues:

1. estimate.js parses callValue but does not pass it into the contract call, so payable-call estimates can still be inaccurate.
2. status.js is still using getTronWeb(), so this read-only resource query still requires TRON_PRIVATE_KEY.

Please fix those and I can re-review.

Also fixed a related bug in estimate.js: parameter types were hardcoded as "auto" (invalid in TronWeb 6.x), causing all calls with parameters to fail. Types are now extracted from the function selector

Thanks for the latest updates. I re-checked the current head and the code changes appear to address the issues I previously flagged.

The remaining concern is runtime verification. Since this skill affects resource estimation and staking-related flows, could you provide a reproducible E2E test transcript covering:

1. status.js for both the configured wallet and an explicit wallet address,
2. estimate.js including a case with non-zero callValue,
3. one small staking-related action (or a clearly documented dry-run if you intentionally did not execute on-chain),
4. final verification showing the resulting resource/account state.

Please include exact commands, network used, and which steps were executed live.

Wallet used: TMnMGpp5qNT3Qh3MoZGnu4UBN9cHPrmnhu

1. status.js

TRON_NETWORK=nile TRON_PRIVATE_KEY=<key> node scripts/status.js

99.655 TRX, 0 energy, 258/600 bandwidth, no pending unstakes ✅

TRON_NETWORK=nile node scripts/status.js <other-wallet>

2. estimate.js

TRON_NETWORK=nile TRON_PRIVATE_KEY=<key> node scripts/estimate.js <usdt-contract> "transfer(address,uint256)" "<recipient>,1000000"

Estimated energy: 14,650

TRON_NETWORK=nile TRON_PRIVATE_KEY=<key> node scripts/estimate.js <usdt-contract> "transfer(address,uint256)" "<recipient>,1000000" 1000000

Correctly returned REVERT — USDT's transfer() is not payable, so a non-zero callValue is rejected by the EVM. Error surfaced cleanly

3. stake.js

TRON_NETWORK=nile TRON_PRIVATE_KEY=<key> node scripts/stake.js 10 ENERGY --dry-run

Dry-run passed

TRON_NETWORK=nile TRON_PRIVATE_KEY=<key> node scripts/stake.js 10 ENERGY

Transaction

4. Final verification

TRON_NETWORK=nile TRON_PRIVATE_KEY=<key> node scripts/status.js

Energy: 0 → 747 (from 10 TRX staked), TRX balance unchanged (stake is frozen, not spent)

[boboliu-1010]

I was able to validate installation, read-only flows, and --dry-run on Nile, but I could not confirm a successful real stake transaction.

A real stake.js 1 BANDWIDTH run returned a tx_id, but the script still marked the result as failed, and a follow-up chain lookup could not find that transaction. Resource status also did not show a confirmed new stake afterward.

This suggests the real write path or result-handling logic still needs work before this PR can be considered fully validated.

[boboliu-1010]

Static review found one blocking issue:

• delegate.js applies the minimum TRX reserve check before resource delegation, but delegation consumes already-staked ENERGY/BANDWIDTH rather than spending liquid TRX. As written, accounts with low available TRX but sufficient staked resources will be incorrectly blocked from delegating. Please remove or rework this safeguard so it validates the actual delegation preconditions instead of liquid balance.
