What is mog AGENTS.md?

A repository instruction file for Mog, containing rules for safe Git use, verification commands, project boundaries, and supported public areas.

Use it before changing Mog code, especially when selecting checks or deciding where a new feature belongs.

It tells an agent how to check the working tree, avoid destructive actions, run focused tests, and avoid adding unsupported components.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00149	$0.00149
Opus 5.5	$0.00060	$0.00060
Sonnet 5.5	$0.00030	$0.00030

Security

Grade A, and why

mog 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 23d 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.

What it actually says

Mog Repository Instructions

This is the public Mog repository.

Before Work

Check git status --short --branch before editing.
Do not use destructive git commands unless explicitly requested.
Keep private/internal content out of this repository.

Verification

Prefer the smallest relevant check for the area changed.
Common checks:
- cargo test -p mog
- cargo test -p compute-api
- cargo check --workspace --locked

Boundaries

Public surfaces live in compute (engine + Office.js scripting) and file-io. Do not add a Node/N-API host, UI packages, or a custom wb/ws scripting API.

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.
