bindings

bindings is a skill for Claude Code, Codex from Goldziher/ai-rulez. It costs 57 tokens per session (207 once invoked), scanned A, original, MIT.

Rules for connecting a shared core library to programming languages through language bindings. Bindings are the small layer that converts calls, data types, and errors between the core and each language.

In plain words
What is it for?
Use them when designing or reviewing bindings, arranging the core API and native interface, setting up language-specific CI tests, handling generated code, and preserving errors and async behavior.
Why use it?
They help keep business logic in one place and prevent inconsistent errors, broken asynchronous behavior, or hand-edited generated code across languages.

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

bindings 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.

What it actually says

  • Bindings are minimal glue: call the core library, convert types, convert errors — no business logic.
  • Canonical surface: core API first, stable native ABI second, language bindings third.
  • Keep integrations and framework adapters outside language bindings unless they are the binding's public purpose.
  • Give each binding its own language-native test suite and run it in CI.
  • Generated binding and e2e code must not be hand-edited. Change the source schema, generator, or core API instead.
  • Error conversion must preserve context across every boundary: message, numeric code when available, and operation.
  • Async boundaries must match host runtime conventions; do not block event loops, schedulers, or UI threads.

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.

bindings is a skill published in the GitHub repository Goldziher/ai-rulez (140 stars, last pushed yesterday), licensed MIT. It adds 57 tokens to every session and 207 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
