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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00374 | $0.00374 |
| Opus 5 | $0.00187 | $0.00187 |
| Sonnet 5 | $0.00075 | $0.00075 |
| Haiku 4.5 | $0.00037 | $0.00037 |
Grade A, and why
use-base-rules 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 8d 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
Use Base Development Rules
All AI agents working on this project must follow the comprehensive development rules and guidelines defined in:
Key Directive
- Single Source of Truth: All development rules, coding standards, testing practices, and workflow requirements are maintained in
base-standards.md - No Rule Duplication: Do not reference or follow other rule files -
base-standards.mdcontains the complete and authoritative rule set - Always Current:
base-standards.mdis the actively maintained configuration - other rule files may be outdated
What's Included in base-standards.md
- Core Principles: Small tasks one at a time, Test-Driven Development (TDD), type safety, clear naming, incremental changes
- Language Standards: English-only requirement for all technical artifacts
- Specific Standards: Links to detailed standards for:
- Backend development (API, database patterns, testing, security)
- Frontend development (React components, UI/UX guidelines)
- Documentation (structure, formatting, maintenance)
Compliance
Before starting any development work, agents must:
- Read and understand all rules in
base-standards.md - Follow the TDD process and core principles defined there
- Use the specified tools, testing frameworks, and standards
- Maintain the required code quality and type safety standards
- Refer to specific standards documents (backend, frontend, documentation) for detailed guidelines
Remember: base-standards.md is the complete development rulebook for this project.
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.

use-base-rules is a cursor rule published in the GitHub repository LIDR-academy/lidr-specboot (114 stars, last pushed 1mo ago), licensed MIT. It adds 374 tokens to every session, about $0.0019 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.
