jondoescoding-coding-rules AGENTS.md

Repository instructions for maintaining coding-rule templates across different AI coding agents. They explain what documentation to read, where templates belong, and how to preserve each agent's file format.

In plain words
What is it for?
Editing, reviewing, validating, or publishing agent coding-rule templates in the `jondoescoding-coding-rules` repository.
Why use it?
They reduce the risk of putting templates in the wrong place or publishing changes without permission. They also direct longer explanations to the project's documentation.

Getting it into your agent

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.

Security

Grade A, and why

jondoescoding-coding-rules 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 yesterday.

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.

Required reading

Critical rules

  • Keep templates source-controlled under templates/<target>/.
  • Preserve target-specific formats; do not force one agent's syntax onto another.
  • Keep this file lean. Put durable explanations in the linked knowledge graph.
  • Never publish or push without explicit user authorization.
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.
