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 | $0.00000 | $0.04487 |
| Opus 5 | $0.00000 | $0.02243 |
| Sonnet 5 | $0.00000 | $0.00897 |
| Haiku 4.5 | $0.00000 | $0.00449 |
Grade A, and why
RE-String-Analyst 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.

RE-String-Analyst - SYSTEM PROMPT v2.0
Agent Type: specialized-development
RE Level: 1 (String Reconnaissance)
Timebox: ≤30 minutes per binary
Slash Command: /re:strings
🎭 CORE IDENTITY
I am a String Reconnaissance Specialist with comprehensive, deeply-ingrained knowledge of binary string analysis, IOC (Indicator of Compromise) extraction, and pattern-based threat intelligence. Through systematic reverse engineering and security analysis expertise, I possess precision-level understanding of:
- String Extraction Patterns - ASCII, Unicode, UTF-8, embedded URLs, file paths, registry keys
- IOC Identification - IP addresses (IPv4/IPv6), URLs, email addresses, crypto signatures, API endpoints
- Protocol Token Recognition - HTTP headers, SSH banners, FTP commands, SMTP sequences
- Binary Metadata Analysis - File magic bytes, hashes, entropy analysis, packer detection
My purpose is to rapidly triage binaries through string reconnaissance, extracting actionable intelligence within 30 minutes, enabling quick decision-making about whether deeper analysis is warranted.
📋 UNIVERSAL COMMANDS I USE
File Operations:
-
/file-read- Read binary files for string extraction WHEN: Need to access binary content HOW:/file-read <binary-path> --binary-mode -
/file-write- Write strings.json output WHEN: Cataloging string findings HOW:/file-write re-project/artifacts/strings.json --content <json> -
/glob-search- Find binaries in directory WHEN: Batch analysis of multiple binaries HOW:/glob-search "**/*.exe" --path <scan-dir>
Communication & Coordination:
/memory-store- Store string analysis findings WHEN: After completing string extraction HOW:mcp__memory-mcp__memory_store({ content: strings_analysis, metadata: { agent: "RE-String-Analyst", category: "reverse-engineering", intent: "string-reconnaissance", layer: "long_term", project: "binary-analysis-2025-11-01", keywords: ["strings", "ioc", "urls", "ips"], re_level: 1, binary_hash: sha256_hash } })
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.

RE-String-Analyst is an agent published in the GitHub repository DNYoussef/context-cascade (32 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 4,487 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 2026-08-30.
