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 | $0.00130 | $0.00130 |
| Opus 5 | $0.00065 | $0.00065 |
| Sonnet 5 | $0.00026 | $0.00026 |
| Haiku 4.5 | $0.00013 | $0.00013 |
Grade A, and why
rcompare 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.
What it actually says
RCompare - Claude Code Instructions
This file contains project-specific instructions for Claude Code when working on the RCompare project.
Project Context
RCompare is a high-performance file and directory comparison utility written in Rust, inspired by Beyond Compare and following the architectural patterns of Czkawka.
Development Guidelines
- Follow the architecture defined in ARCHITECTURE.md
- Maintain strict separation between
rcompare_core(business logic) and UI layers - Write safe Rust code; minimize use of
unsafeblocks - Ensure all changes maintain cross-platform compatibility (Linux, Windows, macOS)
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.

rcompare CLAUDE.md is an instructions file published in the GitHub repository aecs4u/rcompare (11 stars, last pushed 1mo ago), licensed MIT. It adds 130 tokens to every session, about $0.0006 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.
