An anchoring layer between facts and AI memory

Anchorstate Lab released GMR, a lightweight CLI runtime that binds manual judgments and notes to recomputable observations in a repository, replaying the observation that generated them and warning when the relevant world state changes. The tool, installable via npm or a direct script, supports commands like init, anchor, check, and accept, and is designed to keep notes accountable to facts across refactors and code changes.

Track subjective judgments by anchoring them to recomputable observations in your repository. GMR is a lightweight runtime for binding notes to facts, replaying the observation that generated them, and warning you when the world moves along a direction you declared. GMR is a CLI tool that helps you: - attach a judgment or note to an observable part of a repository - keep that judgment bound to a reproducible observation - detect when the relevant world state has changed - return the notes bound to anchors that moved It is not a linter or rule engine. It is a runtime for anchoring notes to observable state and preserving that binding over time. Use GMR when you want to make a manual judgment accountable: - a contract should still hold after a refactor - a behavioural assumption should still be true after code changes - a note should be surfaced again when the thing it depends on moves GMR keeps the judgment attached to the fact it depends on and reports if that fact changes. If the npm packages are published, install the wrapper package: npm install -g @zongming he/gmr The npm wrapper will load the matching platform bundle, if available. If your operating system or architecture is not supported by the published bundle, the wrapper prints a fallback message and points you to the direct installation script. The repository includes a simple install script for prebuilt releases. If you want a direct binary install without npm: curl -fsSL https://raw.githubusercontent.com/Anchorstate-Lab/GMR/main/dist/install.sh | sh If you are using a fork or mirror, replace Anchorstate-Lab/GMR with your repository path. If you want to build the CLI yourself from this repository: cargo install --path domains/coding/cli --locked --root ~/.local This installs the assembled gmr CLI built from the current workspace. GMR works against a project directory, including repositories with no Rust in them. Run commands with --repo <path default is . . gmr --repo /path/to/project init This creates the local .anchor/ layout, installs the built-in probe bundle, and the first time only writes a Claude Code skill doc to .claude/skills/gmr/SKILL.md — pass --global to write it to ~/.claude/skills/gmr/SKILL.md instead. It does not create anchors or notes for you. Safe to rerun; it never overwrites a file that already exists. gmr --repo /path/to/project anchor src/auth.ts createSession \ -m "sessions expire after 30 minutes because ..." anchor routes the coordinate to a probe, a shape and a position, writes a note under memories/ with that memory, opens the anchor, and binds the note to it — all in one step. Omit -m and the note is left for you to write, reported as unwritten until you do. Equivalently, you can hand-write the note yourself with the same frontmatter and run gmr sync to open it: --- about: src/auth.ts createSession --- Sessions must still be created inside the service boundary Run gmr anchor with no coordinate to open whatever the declarations and notes already ask for — what a fresh clone needs, since the journal doesn't travel with the repository. gmr --repo /path/to/project check --json check evaluates due anchors and exits 1 if any axis a note asked about moved, handing back the notes bound to what moved. It also flags anchors whose declaration no longer matches their live criteria, and anchors standing on a reading a different probe instrument took — resolve those see accept --criteria and rebase below before trusting a quiet result. gmr --repo /path/to/project accept src/auth.ts createSession --why "..." You looked, and what check showed is the new baseline; accept clears the vector and seals the reason permanently into the journal. If a declaration change is pending too, pass --baseline or --criteria explicitly — they're separate judgments and don't share one reason. gmr --repo /path/to/project status --json status reports every anchor, its axes, and the notes bound to it. Reads only. The front door — six verbs gmr --help shows: init — set up .anchor/ , install bundled probes, write the skill doc anchor — watch a coordinate and write the memory that goes with it status — what is being watched, on which axes, with which memories check — did anything move on an axis a memory asked about? accept — take what an anchor now shows as the new baseline, or take a changed declaration's criteria --baseline / --criteria / --all --criteria close — retire an anchor permanently Everything else still works, reachable through gmr help <name : probes list / probes build — list or build available probes sync — open anchors declared by notes and align bindings what anchor with no coordinate runs open — create an anchor directly by hand observe / pass / read — evaluate due anchors, return moved notes, or read raw anchor state reprobe / retransition / reterminal / rebase / restate — hand-drive one part of an anchor's criteria; each needs --why , sealed into the journal bind / reaffirm / cobound — manage reference bindings link — record a relationship between references edges — read journal transitions since a point health — inspect anchor liveness doctor — anchors never observed, with no note, unresolvable, or notes with lint problems unclaimed , bare-key , long-hand , retired requeue — force an anchor back onto the due queue export / import — snapshot and replay store contents Most commands support --repo <path and --json .
