cloudflare-troubleshooting

cloudflare-troubleshooting is a skill for Claude Code, Codex from daymade/claude-code-skills. It costs 61 tokens per session (2,669 once invoked), scanned C, original, MIT.

Instructions for diagnosing Cloudflare setup problems using evidence from its API. Cloudflare is a service for DNS, security, and website traffic management.

In plain words
What is it for?
Use them to investigate redirect loops, SSL errors, DNS problems, and other Cloudflare-related issues after providing the domain and suitable credentials.
Why use it?
They replace guesswork with checks of the actual domain, DNS, SSL, redirect, and account configuration.

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 C, and why

cloudflare-troubleshooting scanned grade C with 2 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 6d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/check_cloudflare_config.py, scripts/fix_ssl_mode.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.

Cloudflare Troubleshooting

Methodology base: the general evidence-driven network-diagnosis discipline (falsification, layered isolation, counter-review) lives in the debugging-network-issues skill. This skill is the Cloudflare domain layer on top of it.

Core Principle

Investigate with evidence, not assumptions. Always query Cloudflare API to examine actual configuration before diagnosing issues. The skill's value is the systematic investigation methodology, not predetermined solutions.

Investigation Methodology

1. Gather Credentials

Request from user:

  • Domain name
  • Cloudflare account email
  • Cloudflare Global API Key (or API Token)

Global API Key location: Cloudflare Dashboard → My Profile → API Tokens → View Global API Key

2. Get Zone Information

First step for any Cloudflare troubleshooting - obtain the zone ID:

curl -s -X GET "https://api.cloudflare.com/client/v4/zones?name=<domain>" \
  -H "X-Auth-Email: <email>" \
  -H "X-Auth-Key: <api_key>" | jq '.'

Extract zone_id from result[0].id for subsequent API calls.

3. Investigate Systematically

For each issue, gather evidence before making conclusions. Use Cloudflare API to inspect:

  • Current configuration state
  • Recent changes (if audit log available)
  • Related settings that might interact

Common Investigation Patterns

Redirect Loops (ERR_TOO_MANY_REDIRECTS)

Evidence gathering sequence:

  1. Check SSL/TLS mode:

    curl -X GET "https://api.cloudflare.com/client/v4/zones/{zone_id}/settings/ssl" \
      -H "X-Auth-Email: email" \
      -H "X-Auth-Key: key"
    

    Look for: result.value - tells current SSL mode

  2. Check Always Use HTTPS setting:

    curl -X GET "https://api.cloudflare.com/client/v4/zones/{zone_id}/settings/always_use_https" \
      -H "X-Auth-Email: email" \
      -H "X-Auth-Key: key"
    
  3. Check Page Rules for redirects:

    curl -X GET "https://api.cloudflare.com/client/v4/zones/{zone_id}/pagerules" \
      -H "X-Auth-Email: email" \
      -H "X-Auth-Key: key"

Files

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

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.

cloudflare-troubleshooting is a skill published in the GitHub repository daymade/claude-code-skills (1,377 stars, last pushed today), licensed MIT. It adds 61 tokens to every session and 2,669 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 2 findings (harvests environment variables, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
