What is YSCV AGENTS.md?

Repository instructions for YSCV, a project whose contributors include both people and coding agents. They define responsibility, required checks, and the workflow for proposing changes.

Use them before preparing or reviewing YSCV changes, especially when checking the required local tests, performance measurements, and pull-request responsibilities.

They make clear that the person submitting a change remains responsible for understanding it, testing it, and supporting any claims about it.

Token cost

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	$0.02988	$0.02988
Opus 5.5	$0.01195	$0.01195
Sonnet 5.5	$0.00598	$0.00598
Haiku 4.5	$0.00299	$0.00299

Security

Grade A, and why

YSCV AGENTS.md 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 2mo 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 — 318 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — rules for AI coding agents working on yscv

This file is the contract between this repository and any AI coding agent (Claude Code, Copilot Workspace, Cursor, Aider, etc.) that proposes changes here. Concrete, enforceable, short.

The same rules apply to human contributors.

Responsibility

Every PR has exactly one responsible party: the human who opens it. This holds whether the diff was hand-typed, drafted by an agent, or copy-pasted from a chat log. By submitting, you assert four things about the change:

You have the right to submit it under this repository's licence.
You have read the code you are submitting and understand what it does. If asked "why this line?", you can answer without re-prompting an agent.
You have run the local gates listed in section 2 and the result is what you say it is. "The agent said tests pass" is not a substitute for running them.
For any performance claim, you measured it yourself on your own hardware and the numbers in the PR description are yours.

There is no "the agent did it" defence. A regression introduced by an agent-drafted patch is the submitter's regression, and reverting or fixing it is the submitter's job.

Disclosure of method: if a change is non-trivial and was drafted with an agent, mention that in the PR description in one line — what the agent did, what you verified. This is for context, not credit; do not add Co-Authored-By: lines for the agent (see section 3).

Anonymous or pseudonymous PRs that exist only to relay agent output without a human standing behind them will be closed unread.

Changes

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.
