PetSwipe-Match-App: Instructions file for Codex

AGENTS.md

PetSwipe-Match-App AGENTS.md is an instructions file for Codex, OpenCode from hoangsonww/PetSwipe-Match-App. It costs 3,567 tokens per session, scanned C, original, MIT.

Project-specific operating rules for PetSwipe, a full-stack pet-adoption application. They define safety limits, repository practices, validation expectations, and how coding agents should work together.

In plain words
What is it for?
Use them when making any code, infrastructure, deployment, or documentation change in the PetSwipe repository.
Why use it?
They prevent risky changes such as deleting files or using destructive Git commands, while keeping edits focused and checked after each change.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is hoangsonww/PetSwipe-Match-App's own configuration. It tells Codex and OpenCode how to work on PetSwipe-Match-App itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything PetSwipe-Match-App configures →

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 C, and why

PetSwipe-Match-App AGENTS.md scanned grade C with 1 finding 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 8d 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

2. **No destructive git commands**: `git reset --hard`, `git clean -fd`, `rm -rf`, `git push --force` are forbidden unless the human explicitly requests them.

Rule 0: Override Prerogative

The human operator's instructions override everything in this file. If a human tells you to do something that contradicts a rule below, follow the human.


Rule 1: Core Safety Rules

  1. Never delete files without explicit human permission.
  2. No destructive git commands: git reset --hard, git clean -fd, rm -rf, git push --force are forbidden unless the human explicitly requests them.
  3. All work happens on the main branch unless the human instructs otherwise.
  4. No script-based code changes: always edit files manually through your editor tools. Do not generate and execute sed/awk/perl one-liners to modify source code.
  5. No file proliferation: do not create mainV2.ts, app-backup.ts, or similar variants. Edit in place.
  6. Compiler and lint checks after every change: run the appropriate validation command (see Validation Guidance below) before declaring work complete.
  7. Multi-agent awareness: never stash, revert, or overwrite changes made by other agents. Treat other agents' uncommitted and committed work as your own. If you encounter a merge conflict, stop and notify the human.

Project Overview

PetSwipe is a full-stack pet adoption platform. Users browse adoptable pets via a swipe interface, match with pets they like, and connect with shelters. The codebase spans a Next.js frontend, an Express API backend, Kubernetes manifests, Terraform IaC, and operational scripts.

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.
