Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.03973 | $0.03973 |
| Opus 5 | $0.01987 | $0.01987 |
| Sonnet 5 | $0.00795 | $0.00795 |
| Haiku 4.5 | $0.00397 | $0.00397 |
Grade A, and why
SubFrame 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.

How it starts
The opening of the file, as written. The whole thing — 402 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SubFrame - SubFrame Project
This project is managed with SubFrame. AI assistants should follow the rules below to keep documentation up to date.
Note: This file is named
AGENTS.mdto be AI-tool agnostic. CLAUDE.md and GEMINI.md contain a reference to this file.
Core Working Principle
Only do what the user asks. Do not go beyond the scope of the request.
- Implement exactly what the user requested — nothing more, nothing less.
- Do not change business logic, flow, or architecture unless the user explicitly asks for it.
- If a user asks for a design change, only change the design. Do not refactor, restructure, or modify functionality alongside it.
- If you have additional suggestions or improvements, present them as suggestions to the user. Never implement them without approval.
- The user's request must be completed first. Additional ideas come after, as proposals.
Relationship to Native AI Tools
SubFrame enhances native AI coding tools — it does not replace them.
Claude Code works exactly as normal. Built-in features (/init, /commit, /review-pr, /compact, /memory, CLAUDE.md) are fully supported. CLAUDE.md is Claude Code's native instruction file — users can add their own tool-specific instructions freely. SubFrame adds a small backlink reference pointing to this AGENTS.md file using HTML comment markers (<!-- SUBFRAME:BEGIN --> / <!-- SUBFRAME:END -->). SubFrame will never overwrite user content in CLAUDE.md.
Gemini CLI works exactly as normal. Built-in features (/init, /model, /memory, /compress, /settings, GEMINI.md) are fully supported. GEMINI.md is Gemini CLI's native instruction file — same backlink approach as CLAUDE.md. Users can add their own instructions freely and SubFrame won't overwrite them.
Codex CLI gets SubFrame context via a wrapper script at .subframe/bin/codex that injects AGENTS.md as an initial prompt.
This file (AGENTS.md) contains SubFrame-specific rules that apply across all tools:
- Sub-Task management (
.subframe/tasks/*.md, index at.subframe/tasks.json) - Codebase mapping (
.subframe/STRUCTURE.json) - Context preservation (
.subframe/PROJECT_NOTES.md) - Internal docs and changelog (
.subframe/docs-internal/) - Session notes and decision tracking
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.

SubFrame AGENTS.md is an instructions file published in the GitHub repository Codename-11/SubFrame (10 stars, last pushed 7d ago), licensed MIT. It adds 3,973 tokens to every session, about $0.0199 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
