competition-graphql-rpc-drift

competition-graphql-rpc-drift is a skill for Codex from xAmirHamza77/ReverseOps-Skill. It costs 114 tokens per session (639 once invoked), scanned A, a copy of competition-graphql-rpc-drift, MIT.

A specialized workflow for comparing GraphQL and RPC contracts with the code that handles requests. GraphQL and RPC are ways for software clients to call server operations; OpenAPI is a common format for describing HTTP APIs.

In plain words
What is it for?
Use it in a CTF sandbox to inspect schemas, persisted queries, generated clients, API manifests, and live handlers, then reproduce a contract mismatch.
Why use it?
It helps reveal operations that are missing, outdated, hidden, or handled differently from what the declared interface says.

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

competition-graphql-rpc-drift 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 9d 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.

Competition Graphql Rpc Drift

Use this skill only as a downstream specialization after $ctf-sandbox-orchestrator is already active and has established sandbox assumptions, node ownership, and evidence priorities. If that has not happened yet, return to $ctf-sandbox-orchestrator first.

Use this skill when the hard part is matching declared contracts with live handlers to find hidden, stale, or privileged operations.

Reply in Simplified Chinese unless the user explicitly requests English.

Quick Start

  1. Collect the declared contract surface first: schema, manifest, generated client, persisted query map, or OpenAPI spec.
  2. Record actual request shapes, operation names, variables, method, path, and auth context before mutating anything.
  3. Compare declared contract, generated client behavior, and live handler behavior side by side.
  4. Preserve one accepted operation and one drifted or hidden operation with the smallest delta.
  5. Reproduce the smallest contract-to-handler mismatch that proves the decisive branch.

Workflow

1. Map The Declared Contract Surface

  • Record GraphQL schema, introspection output, persisted query ids, RPC manifests, generated clients, or OpenAPI documents that define the intended surface.
  • Note versioned endpoints, client-only guards, hidden enums, optional fields, and operation naming conventions.
  • Keep document source and generation path tied to the observed requests.

2. Prove Live Handler Behavior

  • Capture the real request and response pairs, including operation name, variables, headers, cookies, and status.
  • Compare client-side validation, schema expectations, and live handler normalization or fallback behavior.
  • Record hidden operations, stale fields, undocumented methods, or handler-only branches that still execute.

3. Reduce To The Decisive Drift Path

  • Compress the result to the smallest sequence: declared contract -> actual request -> handler branch -> resulting capability.
  • State clearly whether the decisive drift lives in generated client assumptions, persisted query mapping, schema version skew, RPC manifest mismatch, or handler-side hidden logic.
  • If the task shifts into generic JWT, OAuth, or queue behavior after acceptance, hand off to the tighter specialized 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.
