debug-node-tracingDebug World Chain nodes with temporary admintracingDirectives log filters and targeted log collection.
Debug Node Tracing is an agent skill from worldcoin/world-chain. Debug World Chain nodes with temporary admintracingDirectives log filters and targeted log collection. Use for live Flashblocks, networking, pool, builder, or validator debugging; not EVM transaction traces.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Debugging and Smart contracts. The licence is MIT.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 2b7dfe8. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
kubectlFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use kubectl, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
ETH_RPC_JWT_SECRETFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Debug Node Tracing loads about 1.1k tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 525 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/debug-node-tracing/SKILL.md (or your agent's skills folder).Use World Chain's admin_tracingDirectives RPC to change a running node's log filter for a bounded time. Adapted from the local nodl skill; verify behavior against crates/rpc/src/admin.rs, crates/cli/src/app.rs, and crates/node/src/add_ons.rs.
debug for 120 seconds; use trace only when needed.admin in an enabled --http.api or --ws.api at startup. This RPC uses that HTTP/WS server, not the Engine API on 8551.Builders require VPN access and pod port-forwarding in world-chain-builder. Contexts are tfh-crypto-{dev,stage,prod}-eu-central-2. Load the matching JWT from the configured secret store without printing it; port 8545 also requires authentication in this deployment.
Stage example; change the context, pod, and credential together for another target:
kubectl --context tfh-crypto-stage-eu-central-2 -n world-chain-builder \
port-forward --address 127.0.0.1 --pod-running-timeout=30s \
pod/world-chain-builder-0 18545:8545Keep that process running while collecting logs. Select targets from the deployed code's target: fields; examples in this repository include flashblocks::p2p, flashblocks::payload_builder, and flashblocks::state_executor.
The following example assumes the stdout baseline is info. Preserve any required baseline directives in the replacement filter:
ETH_RPC_JWT_SECRET="$JWT_STAGE" cast rpc admin_tracingDirectives \
'{"directives":"info,flashblocks::p2p=debug","ttlSecs":120}' \
--rpc-url http://localhost:18545 --rpc-timeout 15cast mints the bearer token from the raw JWT secret. Its flag is --jwt-secret; nodl uses --jwt and does not wrap this custom method. Never print credentials or enable shell tracing around authenticated commands.
Use camelCase ttlSecs. The allowed TTL is 1–3600 seconds; trimmed directives must be nonempty and at most 1024 bytes. Save the successful response's applied, ttlSecs, and revertsTo fields. A timeout leaves application uncertain; inspect logs before retrying, since a retry replaces the timer.
revertsTo as directives and ttlSecs: 1. Do this only while your override still owns the session; do not overwrite a newer operator's filter.world_chain::admin revert message or a revert failure. If restoration cannot be observed, report it as unverified. Stop the port-forward you started.401: verify the environment's JWT and forwarded port; do not remove authentication.-32601 Method not found: check the deployed version, namespace, and port. Local source alone does not establish deployed support.tracing reload is not active: startup did not install reload support. Report the required startup flag change; it cannot be enabled through this RPC.© worldcoin, MIT.

Debug World Chain nodes with temporary admintracingDirectives log filters and targeted log collection. Debug Node Tracing is an agent skill from worldcoin/world-chain. Debug World Chain nodes with temporary admintracingDirectives log filters and targeted log collection.
Debug Node Tracing fits situations like: live Flashblocks; validator debugging; not EVM transaction traces.
Run `npx skills add worldcoin/world-chain --skill debug-node-tracing -a claude-code`. Or copy the skill folder (.agents/skills/debug-node-tracing in worldcoin/world-chain) into .claude/skills/debug-node-tracing in your project. Claude Code loads it when a task matches its description.
Run `npx skills add worldcoin/world-chain --skill debug-node-tracing -a codex`. Or copy the skill folder (.agents/skills/debug-node-tracing in worldcoin/world-chain) into .agents/skills/debug-node-tracing in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add worldcoin/world-chain --skill debug-node-tracing -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/debug-node-tracing, .gemini/skills/debug-node-tracing, .github/skills/debug-node-tracing and .opencode/skills/debug-node-tracing in your project.
Going by SKILL.md and its folder, Debug Node Tracing needs the command-line tools its instructions call (kubectl) and credentials named ETH_RPC_JWT_SECRET. Our summary lists: A credential in ETH_RPC_JWT_SECRET.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Debug Node Tracing is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.1k tokens (SKILL.md is roughly 4.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
