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 | $0.00050 | $0.00320 |
| Opus 5 | $0.00025 | $0.00160 |
| Sonnet 5 | $0.00010 | $0.00064 |
| Haiku 4.5 | $0.00005 | $0.00032 |
Grade A, and why
clean-code 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.
What it actually says
Clean code (general)
When to use
Always, while writing or changing code — independent of stack or lane.
Rules
- Small, single-responsibility files. No god classes/functions. If it does two unrelated things, split it.
- Names say intent. Prefer clear over clever; no cryptic abbreviations.
- Respect module boundaries. Domains don't import each other; shared contracts live in one place.
- Handle errors explicitly. Type them where the stack allows; log with context; never silently swallow.
- Validate at boundaries. Trust nothing crossing an edge (input, config, IO).
- Comments explain "why", not "what". In the repo language only.
- No dead code, no commented-out blocks. Delete it; git remembers.
- Deny by default for anything authorization-related.
Notes
This is the always-on baseline. Project-type skills (added after the interview) layer stack-specific conventions on top — they refine these rules, never relax them.
ponytail is the always-on sibling: this skill governs the shape of the
code, ponytail governs how much of it exists. They apply together.
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.

clean-code is a skill published in the GitHub repository 0xBeycan/genesis (11 stars, last pushed 1mo ago), licensed MIT. It adds 50 tokens to every session and 320 once invoked, about $0.0003 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.
