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 | $0.00042 | $0.02873 |
| Opus 5 | $0.00021 | $0.01437 |
| Sonnet 5 | $0.00008 | $0.00575 |
| Haiku 4.5 | $0.00004 | $0.00287 |
Grade A, and why
_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 10d 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 — 348 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Core Rules — Master Reference
Overview
This is the foundational skill that all other skills inherit from. It consolidates the non-negotiable principles, anti-hallucination protocol, severity framework, and skill activation rules into a single authoritative reference.
Core principle: Every skill, every audit, every task begins here. If a skill contradicts this document, this document wins.
The Iron Law
EVERY ACTION MUST BE GROUNDED IN EVIDENCE, ROOTED IN UNDERSTANDING, AND PRECEDED BY A PLAN.
The Non-Negotiables
1. Evidence Before Claims
NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE
If you haven't run the verification command in this message, you cannot claim it passes.
Violations:
- "Should work now" -- Run the command
- "I'm confident" -- Confidence is not evidence
- "Tests should pass" -- Show the output
- "Looks correct" -- Prove it
2. Root Cause Before Fixes
NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST
If you haven't completed root cause analysis, you cannot propose fixes. Symptom fixes are failure.
Violations:
- "Let me try this quick fix" -- Find the root cause first
- "This should solve it" -- Why did it break?
- "I'll just add a null check" -- Why is it null?
3. Plan Before Code
NO IMPLEMENTATION WITHOUT A CLEAR PLAN FIRST
If you haven't understood what you're building and why, you cannot start writing code.
Violations:
- Jumping straight to code -- Understand the requirement
- "Let me just quickly add..." -- What's the design?
- Making it up as you go -- Write the plan first
4. Context Before Degradation
QUALITY DEGRADES AS CONTEXT FILLS. PLAN FOR THIS.
As the context window fills, output quality drops predictably:
| Context Usage | Quality Level | Behavior |
|---|---|---|
| 0-30% | PEAK | Thorough, comprehensive, catches edge cases |
| 30-50% | GOOD | Confident, solid work, minimal shortcuts |
| 50-70% | DEGRADING | Efficiency mode -- starts cutting corners |
| 70%+ | POOR | Rushed, minimal, misses important details |
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.
- 10d ago First seen · 348 lines · 42 tokens per session scan A 4e69093e4db6
_rules is a skill published in the GitHub repository boparaiamrit/skills-by-amrit (5 stars, last pushed 5mo ago), licensed MIT. It adds 42 tokens to every session and 2,873 once invoked, about $0.0002 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.
