rest-graphql-debug

rest-graphql-debug is a skill for Claude Code, Codex from johnson7788/MultiUserClaw. It costs 21 tokens per session (3,997 once invoked), scanned D, a copy of rest-graphql-debug, MIT.

A guided troubleshooting tool for REST and GraphQL APIs. REST and GraphQL are two common ways software sends requests to web services and receives data.

In plain words
What is it for?
Use it to investigate status-code and authentication errors, webhook failures, unexpected responses, pagination, rate limits, and API integration tests.
Why use it?
It helps locate whether an API problem comes from connectivity, security credentials, request data, response handling, or the meaning of the returned data.

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 D, and why

rest-graphql-debug scanned grade D with 3 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 4d 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

resp = requests.post( "https://api.example.com/graphql",

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

How it starts

The opening of the file, as written. The whole thing — 515 lines — stays where its author put it; the contents beside it link to each section on GitHub.

API Testing & Debugging

Drive REST and GraphQL diagnosis through Hermes tools — terminal for curl, execute_code for Python requests, web_extract for vendor docs. Isolate the failing layer before guessing at the fix.

When to Use

  • API returns unexpected status or body
  • Auth fails (401/403 after token refresh, OAuth, API key)
  • Works in Postman but fails in code
  • Webhook / callback integration debugging
  • Building or reviewing API integration tests
  • Rate limiting or pagination issues

Skip for UI rendering, DB query tuning, or DNS/firewall infra (escalate).

Core Principle

Isolate the layer, then fix. A 200 OK can hide broken data. A 500 can mask a one-character auth typo. Walk the chain in order; never skip a step.

1. Connectivity   → can we reach the host at all?
1.5 Timeouts      → connect-slow vs read-slow?
2. TLS/SSL        → cert valid and trusted?
3. Auth           → credentials correct and unexpired?
4. Request format → payload shape match server expectations?
5. Response parse → does our code accept what came back?
6. Semantics      → does the data mean what we assume?

5-Minute Quickstart

REST via terminal

# Verbose request/response exchange
terminal('curl -v https://api.example.com/users/1')

# POST with JSON
terminal("""curl -X POST https://api.example.com/users \\
  -H 'Content-Type: application/json' \\
  -H "Authorization: Bearer $TOKEN" \\
  -d '{"name":"test","email":"[email protected]"}'""")

# Headers only
terminal('curl -sI https://api.example.com/health')

# Pretty-print JSON
terminal('curl -s https://api.example.com/users | python3 -m json.tool')

GraphQL via terminal

terminal("""curl -X POST https://api.example.com/graphql \\
  -H 'Content-Type: application/json' \\
  -H "Authorization: Bearer $TOKEN" \\
  -d '{"query":"{ user(id: 1) { name email } }"}'""")

GraphQL gotcha: servers often return HTTP 200 even when the query failed. Always inspect the errors field regardless of status code:

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.

It adds 21 tokens to every session and 3,997 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 3 findings (sends data to an external url, downloads and executes remote code, makes network calls). It is 97% identical to rest-graphql-debug, differing in 3 lines, and is treated as a copy.
