Agent Skills: /fix-lightning

/fix-lightning

Fix the highest priority Lightning issue.

What This Does

1. Invoke /check-lightning to audit Lightning health
2. Identify highest priority issue
3. Fix that one issue
4. Verify the fix
5. Report what was done

This is a fixer. It fixes one issue at a time. Run again for next issue. Use /lightning for full lifecycle.

Process

1. Run Primitive

Invoke /check-lightning skill to get prioritized findings.

2. Fix Priority Order

Fix in this order:

1. P0: Node not synced, watchtower not configured
2. P1: Peer connectivity issues
3. P2: Low inbound liquidity, channel rebalancing needed
4. P3: Advanced routing/fees

3. Execute Fix

Node not synced (P0): Confirm chain sync:

lncli getinfo
bitcoin-cli getblockchaininfo

If synced_to_chain=false, restart LND after backend is healthy:

sudo systemctl restart lnd

Watchtower not configured (P0): Enable watchtower client and add a tower:

# lnd.conf
wtclient.active=1

lncli wtclient add --tower_addr=host:9911

Peer connectivity issues (P1): Reconnect to peer:

lncli listpeers
lncli disconnect <pubkey>
lncli connect <pubkey>@host:port

Low inbound liquidity (P2): Open a channel with pushed sats to create inbound:

lncli openchannel --node_key=<pubkey> --local_amt=1000000 --push_amt=200000

Channel rebalancing needed (P2): Move balance from outgoing-heavy to incoming-heavy channel:

lncli listchannels
lncli rebalancechannel --from_chan_id=<from> --to_chan_id=<to> --amount=50000

4. Verify

After fix:

lncli getinfo
lncli listchannels
lncli listpeers

5. Report

Fixed: [P0] Node not synced

Updated: lnd service
- Restarted after chain backend healthy
- Confirmed synced_to_chain=true

Verified: lncli getinfo → synced_to_chain=true

Next highest priority: [P0] Watchtower not configured
Run /fix-lightning again to continue.

Branching

Before making changes:

git checkout -b fix/lightning-$(date +%Y%m%d)

Single-Issue Focus

Lightning is sensitive. Fix one thing at a time:

• Test each change thoroughly
• Easy to rollback specific fixes
• Clear audit trail for ops

Run /fix-lightning repeatedly to work through the backlog.
