Turn background the user keeps re-explaining or re-pasting into reusable instructions, so new chats start with it for free. Use when the user repeats the same context, rules, style guide, persona or reference text across messages or chats, says they are tired of explaining the same thing, or asks how to set up a Claude Project, custom instructions or a CLAUDE.md.
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
# Project context Context pasted into every new chat is paid for again in every chat, and drifts each time it is retyped. Written once as instructions, it costs nothing to bring along and stays the same. ## Collect From this conversation, gather what the user keeps supplying: who they are and what they work on, the audience, rules and constraints, tone and format preferences, terms and names, recurring reference material. Ask one question at most, and only for something essential that isn't in the conversation. ## Write two things, in the user's language **1. Instructions**, in one code block, under 250 words: short imperative lines grouped as *Context*, *Always*, *Never* and *Output*. Keep only what changes the answers. No pleasantries, no restating what Claude does anyway. **2. Reference material**: the long texts (a style guide, a spec, a glossary, a price list) listed by name, to upload as files rather than paste into the instructions. ## Where it goes - **claude.ai or the desktop app**: create a Project, paste the instructions into its custom instructions, and add the reference files to its knowledge. …

How to install
mdr add egorfedorov/claude-context-optimizer/project-context@sha256:99088c5e8b0bb6daThe line at the top of this page pins the label git:20261017.dfb62c2, 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.
