Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01290 | $0.01290 |
| Opus 5 | $0.00645 | $0.00645 |
| Sonnet 5 | $0.00258 | $0.00258 |
| Haiku 4.5 | $0.00129 | $0.00129 |
Grade A, and why
ix-claude-plugin CLAUDE.md 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ix-claude-plugin
For the canonical Ix operating model (command taxonomy, routing, fallback behavior), see
skills/shared.md. This file covers contributing to ix-claude-plugin specifically.
This repo is the Claude Code plugin for Ix Memory. When working in this repo, use ix commands to navigate it just like any other codebase.
This repo contains shipped skills, hook scripts, tests, and marketplace metadata.
Cognitive Model
Claude + Ix operates as a three-layer system:
Ix Graph = structured memory
Claude = reasoning engine
Skills / Agents = task abstractions over the graph
The plugin exists to make that model usable inside Claude Code through install-time teaching, hook-driven context injection, and higher-level reasoning skills.

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.

ix-claude-plugin CLAUDE.md is an instructions file published in the GitHub repository ix-infrastructure/ix-claude-plugin (7 stars, last pushed 4d ago), licensed Apache-2.0. It adds 1,290 tokens to every session, about $0.0064 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 2026-08-31.
