100xprism: Instructions file for Codex

AGENTS.md

100xprism AGENTS.md is an instructions file for Codex, OpenCode from rajitsaha/100xprism. It costs 1,799 tokens per session, scanned A, original, MIT.

A repository instruction file explaining how 100xprism is organized and how coding agents should modify it. It describes modules, generated adapter files, and the project’s rules for preserving source files.

In plain words
What is it for?
Use it when contributing to 100xprism, adding or changing skills, or working with its adapters for different coding tools.
Why use it?
It prevents agents from editing generated output or misunderstanding which files are the source of truth.

Instructions file for CodexOpenCode

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

This is rajitsaha/100xprism's own configuration. It tells Codex and OpenCode how to work on 100xprism 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 100xprism configures →

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

100xprism 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 18d 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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Contributor contract for AI coding agents working on this repo. Users see README.md and docs/USAGE.md; this file is for agents editing the repo itself.

What this repo is

100xprism is a distributor, not an app. The product is modules/ (68 SKILL.md files with YAML frontmatter). Adapters in adapters/ render those modules into each AI tool's native format: Claude Code skills, Cursor .mdc, Codex repo skills + AGENTS.md, a Pi package (retention-filtered .pi/skills/ + extensions), and Hermes/OpenClaw global skills. Users install via npm i -g 100xprism or get.sh. For Pi: pi install git:github.com/rajitsaha/100xprism.

Every adapter uses progressive disclosure — descriptions in the always-on index, bodies loaded on demand. The single-file concat adapters (Windsurf/Copilot/Gemini/Antigravity) were removed in v3.0.0 precisely because they could not do this.

The golden rule

A module is the source of truth. Adapter output is generated. Edit modules/<slug>/SKILL.md. Never hand-edit ~/.claude/skills/*, .cursor/rules/*.mdc, .pi/skills/*, or any rendered artifact in a consumer project — those are reset by the next adapter run.

Module shape

Each module is one file: modules/<slug>/SKILL.md with frontmatter:

---
name: <slug>
description: <one-line trigger guidance — used by Claude Code/Cursor for auto-activation>
category: <docs|code|growth|...>
tier: <core|on-demand>
slash_command: /<name>   # optional — only for the 28 command-style modules
retention: <must|profile|resolver>   # optional — overrides the derived class
profiles: <core, code, data, …>      # optional — overrides the category default
---

A module must work across all 5 adapters. If you add tool-specific instructions, gate them inside the module body, not the frontmatter. Hermes has one extra constraint the others don't: its always-on index truncates description: past ~57 chars, so adapters/lib/modules.py's hermes_description() re-derives a short one for that adapter only (override per-module with hermes_description: in frontmatter if the derived cut reads awkwardly) — the source module's description: is unaffected.

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.
