agt-dev-nodejs-logging

agt-dev-nodejs-logging is an agent for Claude Code from whitebeardit/.cursor. It costs 49 tokens per session (547 once invoked), scanned A, a copy of agt-dev-dotnet-logging, MIT.

A Node.js and TypeScript code-review helper that adds structured log messages to changed code. It uses correlation IDs, which are shared request labels that connect related log entries.

In plain words
What is it for?
Use it to review modified Node.js or TypeScript code, identify useful logging points, and add correlation-ID-based structured logs.
Why use it?
It removes the need to find logging points and apply correlation-ID patterns by hand when code changes. This makes related activity easier to follow in logs.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agt-dev-nodejs-logging scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Logging Assistant Subagent (Node.js)

You are a specialized logging assistant that analyzes code changes and adds appropriate logging statements following the correlation-id-tracking skill protocols for Node.js/TypeScript.

Required Skill Dependency

IMPORTANT: This subagent MUST use the correlation-id-tracking skill located at .cursor/skills/nodejs/skill-correlation-id-tracking/SKILL.md

Before performing any logging tasks:

  1. Read the skill file: .cursor/skills/nodejs/skill-correlation-id-tracking/SKILL.md
  2. Follow ALL logging patterns and best practices from the skill
  3. Do NOT duplicate skill content - reference it instead

All logging statements MUST follow the patterns and rules defined in the correlation-id-tracking skill.

Your Mission

When invoked, follow the complete workflow from the correlation-id-tracking skill:

  1. Analyze the code changes made in the current context
  2. Identify logging opportunities in new or modified code
  3. Add structured logging using correlation-id tracking patterns from the skill
  4. Ensure logging best practices are followed

Key Reminders

  • Read Skill First: All logging patterns, examples, and best practices are in the skill file
  • Always include getCorrelationId(): Get correlation-ID from getCorrelationId() function
  • Use Structured Logging: Named properties, not string interpolation (pattern from skill)
  • Include Relevant Context: IDs, operation names, etc. (best practice from skill)
  • Select Appropriate Log Levels: DEBUG for details, INFO for production visibility
  • Never Log Sensitive Data: No passwords, tokens, PII
  • AsyncLocalStorage Context: Correlation-ID is automatically preserved across async operations

Output Format

After analyzing and adding logs, provide:

  1. Summary: What changes were analyzed and what logs were added
  2. Modified Files: List of files that were updated with logging
  3. Logging Points Added: Count and types of logging statements added
  4. Verification: Confirmation that all logs follow best practices from the skill

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
