Fix RPC URLs

Apply RPC URL changes to a chain's GCP secret and optionally refresh K8s resources.

When to Use

1. After diagnosis: User ran /debug-rpc-provider, saw the recommendation, and says "fix it" or "apply the fix"
2. Direct request: User provides a chain and explicit list of new RPC URLs to set

Input Parameters

The skill parses parameters from conversation context (typically from /debug-rpc-provider output):

Parameter	Required	Source	Description
chain	Yes	Conversation context	Chain name (e.g., ethereum)
environment	Yes	Conversation context or mainnet3	mainnet3 or testnet4
rpcUrls	Yes	Debug skill's proposed URL list	JSON array of full RPC URLs
refreshK8s	No	User request, default false	Whether to refresh K8s resources

Workflow

Step 1: Find Monorepo Root

MONOREPO_ROOT=$(git rev-parse --show-toplevel)

Step 2: Parse Parameters from Context

Extract from the conversation:

• chain and environment from the debug skill invocation or user message
• rpcUrls from the "Proposed new RPC URLs" JSON array in the debug skill output

If any required parameter cannot be found, output what's missing and stop.

Step 3: Log the Change

Before making changes, output what will happen:

Applying RPC URL changes for <chain> (<environment>):
New URLs: ["https://url1", "https://url2"]
Refresh K8s: yes/no

Step 4: Apply the Change

Run the set-rpc-urls script in non-interactive mode:

pnpm --dir "$MONOREPO_ROOT/typescript/infra" exec tsx scripts/secret-rpc-urls/set-rpc-urls.ts \
  -e <environment> -c <chain> \
  --rpc-urls '<JSON array of URLs>' \
  --refresh-k8s --yes

Omit --refresh-k8s if the user explicitly said not to refresh, or if kubectl access is unavailable.

The script validates each URL before applying. If validation fails, it will error out and no changes are made.

Note: URL validation is EVM-only — for non-EVM chains (Cosmos, Sealevel, Radix, etc.) testProvider short-circuits and returns healthy without probing. For those chains, double-check the URL set yourself before invoking this skill.

Step 5: Verify the Fix

Run the debug script again to confirm the new URLs are healthy:

pnpm --dir "$MONOREPO_ROOT/typescript/infra" exec tsx scripts/secret-rpc-urls/debug-rpc-url-health.ts \
  -e <environment> -c <chain>

Step 6: Report Results

Output a summary:

RPC URL update for <chain> (<environment>): SUCCESS/FAILED

- Secret updated: yes/no
- K8s resources refreshed: yes/no/skipped
- Verification: all healthy / X of Y healthy

Error Handling

Error	Action
Provider validation fails	Report which URL failed. No changes made. Suggest user provide different URLs.
Secret update fails	Report error. Check GCP permissions.
K8s refresh fails	Report error. Secret was already updated. Suggest manual kubectl refresh.
Verification shows unhealthy	Report the verification output. The URLs were set but may need further investigation.

Important Notes

• No interactive prompts. This skill does not ask the user. The human-in-the-loop gate is the act of invoking /fix-rpc-urls itself.
• The URLs from /debug-rpc-provider output can be passed directly.
• The set-rpc-urls.ts script always validates URLs before applying for EVM chains — there is no way to skip validation. Non-EVM chains skip URL probing.
• If --refresh-k8s is used, the script refreshes all dependent K8s resources (relayers, validators, scrapers, warp monitors, rebalancers, cronjobs) without prompting.
