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.

What it costs to keep this loaded
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 | $0.00063 | $0.01999 |
| Opus 5.5 | $0.00025 | $0.00800 |
| Sonnet 5.5 | $0.00013 | $0.00400 |
| Haiku 4.5 | $0.00006 | $0.00200 |
Grade A, and why
code-simplifier 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 1mo 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 — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Community Code Simplification Best Practices
Comprehensive code simplification guide for AI agents and LLMs. Contains 47 rules across 8 categories, prioritized by impact from critical (context discovery, behavior preservation) to incremental (language idioms). Each rule includes detailed explanations, real-world examples comparing incorrect vs. correct implementations, and specific impact metrics.
Core Principles
- Context First: Understand project conventions before making any changes
- Behavior Preservation: Change how code is written, never what it does
- Scope Discipline: Focus on recently modified code, keep diffs small
- Clarity Over Brevity: Explicit, readable code beats clever one-liners
When to Apply
Reference these guidelines when:
- Simplifying or cleaning up recently modified code
- Reducing nesting, complexity, or duplication
- Improving naming and readability
- Applying language-specific idiomatic patterns
- Reviewing code for maintainability issues
Rule Categories by Priority
| Priority | Category | Impact | Prefix | Rules |
|---|---|---|---|---|
| 1 | Context Discovery | CRITICAL | ctx- |
4 |
| 2 | Behavior Preservation | CRITICAL | behave- |
6 |
| 3 | Scope Management | HIGH | scope- |
5 |
| 4 | Control Flow Simplification | HIGH | flow- |
9 |
| 5 | Naming and Clarity | MEDIUM-HIGH | name- |
6 |
| 6 | Duplication Reduction | MEDIUM | dup- |
5 |
| 7 | Dead Code Elimination | MEDIUM | dead- |
5 |
| 8 | Language Idioms | LOW-MEDIUM | idiom- |
7 |

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.
- 1mo ago First seen · 134 lines · 63 tokens per session scan A 1850c855a636
code-simplifier is a skill published in the GitHub repository pproenca/dot-skills (215 stars, last pushed 2mo ago), licensed MIT. It adds 63 tokens to every session and 1,999 once invoked, about $0.0003 per session on Opus 5.5. 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.
