ai-fication-kit: Instructions file for Codex

AGENTS.md

ai-fication-kit AGENTS.md is an instructions file for Codex, OpenCode from kunalsuri/ai-fication-kit. It costs 850 tokens per session, scanned A, original, Apache-2.0.

General instructions for AI coding assistants working on ai-fication-kit, a toolkit that builds a trusted map of an existing or legacy codebase. They define how to locate code, preserve structure, test changes, and label project knowledge.

In plain words
What is it for?
Use them when exploring the repository, planning or implementing features, fixing bugs, writing knowledge-base entries, running tests, or reviewing whether documentation has drifted.
Why use it?
They reduce accidental changes in unfamiliar code and keep the project's documentation traceable. They also set expectations for testing, licensing, and small, focused edits.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions AGENTS.md.

This is kunalsuri/ai-fication-kit's own configuration. It tells Codex and OpenCode how to work on ai-fication-kit 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 ai-fication-kit 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 A, and why

ai-fication-kit 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 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.

AGENTS.md — ai-fication-kit

Tool-agnostic instructions for any AI coding agent (Claude Code, Codex, Cursor, Copilot, Windsurf). Claude Code reads these via @AGENTS.md in CLAUDE.md (see CLAUDE.md); other tools read this file directly.

Project

A Toolkit to Give AI Coding Agents a Trusted Map of Any Existing/Legacy Repo Stack: JavaScript/TypeScript.

Rules every agent must follow

  1. Respect existing boundaries. Treat unfamiliar, load-bearing code as frozen until the module map says otherwise.
  2. No layout churn. Don't reorganize directories; existing contributors depend on the structure.
  3. Test before done. Run the suite matching your change; never declare success untested. Build: npm install · Test: npm test
  4. Match license headers on every new source file, copying from neighboring files.
  5. Locate, then read. Use ai/guide/MODULE_MAP.md to find code; grep before reading whole files.
  6. Surgical diffs. Change only what the task needs.
  7. Provenance. Anything you write into ai/ is [inferred] until a human flips it to [verified]. Never flip that tag yourself.
  8. No Phantom Bugs & Configuration Churn. Do not rewrite, restructure, or simplify configuration or instruction files (CLAUDE.md, AGENTS.md, package.json, or ai/guide/ documents) based on quick searches or automated suggestions. Keep edits surgical. Never replace detailed guides with simplified stubs.
  9. Verify claims. Before declaring a task finished, run node install.mjs verify . --strict (or equivalent test runner validation script) to ensure no file paths in the knowledge documents are broken.
  10. Record work. Every unit of work ends with an appended row in ai/lab/WORKLOG.md linking its spec, review, and commits — even work done outside the command workflows.

Knowledge map

Navigation (fast path): ai/guide/MODULE_MAP.md (where code lives), ai/guide/ARCHITECTURE.md (system shape), ai/guide/FEATURE_MAP.md (feature → files

  • gotchas), ai/guide/CONVENTIONS.md (how to write code here).

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.
