Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# MarketMirror for Codex

When the user wants to test ads, messages, offers, prices, emails, launches, positioning or a sales pitch on an audience, predict how customers will react, analyse past ad results, estimate cost per lead or ROI, or asks what real people say about a product: use the **market-mirror** skill (`~/.codex/skills/market-mirror/SKILL.md`) and its MCP tools (`understand`, `research`, `quickstart`, `market_test`, `run_test`, `email_test`, `pitch`, `study`, `predict`, `calibrate`, `ideas`, `ad_patterns`, `push_context`, `results`, `start_live`).

Order of work: `understand` the product, `research` what real people say, `quickstart` the scenario, show the simulated people, then run the tests with `approve_spend`, then report the decision with its confidence and limits. Simulated people are not real people: give directions and margins, never measurements. Never print the API key. Without a key, `mm.sh gateway start codex` runs the engine on the ChatGPT login (personal use).

How to install

The exact contents, by fingerprint
mdr add darkworldcoder/market-mirror/codex/AGENTS.md@sha256:d5db09b7caf80509

The line at the top of this page pins the label git:20261029.7669863, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
