sigil-lang: Agent for Claude Code

.claude/agents/llm-integration-expert.md

llm-integration-expert is an agent for Claude Code from Daemoniorum-LLC/sigil-lang. It costs 0 tokens per session (767 once invoked), scanned A, original, no licence file.

An expert helper for building software that uses large language models, such as OpenAI, Anthropic, or Google models.

In plain words
What is it for?
Use it for model API integrations, prompt design, embedding and RAG systems, streaming, tool or function calls, context handling, token use, and fine-tuning workflows.
Why use it?
It helps with the specialised decisions involved in connecting language models to an application and managing prompts, text limits, and responses.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is Daemoniorum-LLC/sigil-lang's own configuration. It tells Claude Code how to work on sigil-lang itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything sigil-lang configures →

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

llm-integration-expert 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.

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.

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.

llm-integration-expert is an agent published in the GitHub repository Daemoniorum-LLC/sigil-lang (5 stars, last pushed today), with no licence file. It costs nothing until one of its globs matches a file; then it loads 767 tokens. 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.
