long-context

long-context is a skill for Claude Code from OpenLAIR/dr-claw-plugin-cc. It costs 74 tokens per session (4,249 once invoked), scanned A, original, no licence file.

A set of techniques for helping transformer models work with much longer text than their original context window allows. A context window is the amount of text a model can consider in one request.

In plain words
What is it for?
Use it to process long documents, extend pretrained models to 32k–128k or more tokens, and implement methods such as RoPE, YaRN, ALiBi, and position interpolation.
Why use it?
It helps when documents exceed the model’s normal input limit, such as texts containing tens of thousands of tokens.

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

long-context 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 2d 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What ships with it

3 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.

long-context is a skill published in the GitHub repository OpenLAIR/dr-claw-plugin-cc (5 stars, last pushed 3mo ago), with no licence file. It adds 74 tokens to every session and 4,249 once invoked, about $0.0004 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 2026-09-03.
