network

network is a skill for Claude Code from v0idOS/performance-deity. It costs 32 tokens per session (287 once invoked), scanned A, original, MIT.

A skill for reducing the amount of data APIs send and the time requests take over a network.

In plain words
What is it for?
Use it to measure response sizes, check gzip or Brotli compression and HTTP caching, and consider GraphQL, Protocol Buffers, server-sent events, or WebSockets for heavy or real-time endpoints.
Why use it?
It helps find oversized responses, missing compression or caching, and inefficient ways of sending frequently requested 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 A, and why

network 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.

What it actually says

Execute all four phases in order.

Phase 1 — Payload Profiling

  1. Identify the API endpoint.
  2. Measure the raw JSON response size in bytes.
  3. Identify the nested or repeated structures contributing the most bytes.

Phase 2 — Compression & Caching

  1. Check response headers. Verify Content-Encoding: gzip or Content-Encoding: br is present. If not, enable it server-side.
  2. Add HTTP caching headers:
    • Cache-Control: max-age=<N>, stale-while-revalidate=<N>
    • ETag for conditional GET support

Phase 3 — Serialization

If the payload exceeds 1MB:

  • Migrate to GraphQL so clients request only the fields they need, or
  • Migrate to Protocol Buffers (protobuf) for binary serialization.
  • For real-time data, use Server-Sent Events or WebSockets to eliminate repeated full-payload polling.

Phase 4 — Report

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.

network is a skill published in the GitHub repository v0idOS/performance-deity (2 stars, last pushed 5mo ago), licensed MIT. It adds 32 tokens to every session and 287 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
