Anchr

With ⚓, Drift is Okay.

Anchr is a VSCode extension and repo-level protocol framework for guarding AI coding agents against drift, hallucinated verification, scope creep, and false completion.

What It Does

Anchr installs a .anchr/ protocol folder into a workspace. AI agents read the manifesto, work one atomic step at a time, and write .anchr/out/signal.json after each step. The VSCode daemon watches that signal file and runs deterministic checks before the agent continues.

On success, the status bar stays active. On violation, Anchr enters HARD STOP, writes a lock file, shows a VSCode notification, and prevents further signal processing until a human clears the lock.

The current hardening layer adds locked-goal evidence, bounded decomposition, rule/domain-confidence evidence, two-run test attestation, high-impact action approval, raw signal rate/blocklist protection, procedure memory, and graph regression checks. It also records session-isolated quality/relevance/style telemetry, enforces deterministic locked-goal relevance at the signal boundary, requires ABA re-anchor evidence after style drift, evaluates six drift metrics, and ships a production-code red-team latency suite. These are local feature vectors, not provider embeddings. Provider ensembles, provider embeddings, and multi-agent routing remain runtime-bound unless Anchr owns that execution boundary.

Requirements

Anchr's protocol checks run through the anchr_tools.py CLI, so Python 3.10+ must be on your PATH (python3/python on macOS/Linux, python/py on Windows). The extension shows a warning on activation if no Python launcher is found. A Git repository is also required — the daemon refuses to run outside one.

Main Commands

• Anchr: Initialize in Workspace
• Anchr: Start Daemon
• Anchr: Stop Daemon
• Anchr: Show Status
• Anchr: Open Panel
• Anchr: Clear Hard Stop Lock
• Anchr: Sync - Re-verify Audit State

Source of Truth

Configuration is intentionally kept in .anchr/config.yml. VSCode settings are not used for daemon behavior in v1, so the workspace protocol remains auditable and portable across agents.

Privacy & Telemetry

Anchr collects no telemetry. In standard mode it runs entirely locally — the daemon, the anchr_tools.py checks, and the panel never contact any server. The only network calls Anchr makes are the ones you explicitly trigger by signing in: Google OAuth and the Anchr auth service at https://auth.anchr.dev for enterprise entitlement and billing. No code, signal, audit finding, or workspace content is ever sent anywhere.
