+# Friction log
+
+Friction hit while working in this repository, one directory per item:
+
+```
+<id>/
+  friction.md   the write-up
+  artifacts/    optional, whatever reproduces it
+```
+
+Reporting an entry gives it an owner. The write-up then carries an `issue:` link and mirrors what happens
+to it. The whole directory is deleted once the friction is resolved. Every entry left here is still
+outstanding, including friction in dependencies.
+
+Do not maintain an index here. This directory is the index.
+
+## Logging Friction
+
+```sh
+frog list    # what is already known
+frog log     # add one
+```
+
+`frog log` writes the sections to fill in. Each id is when the friction was hit plus its title, so
+the directory reads oldest-first.
+
+Put anything that reproduces the friction in that entry's `artifacts/` and reference it from the
+write-up. The next reader runs the reproduction instead of rebuilding it.
+
+## For Agents
+
+These rules live in `CLAUDE.md`, which `AGENTS.md` points at, so amend them there rather than duplicating them into `AGENTS.md`.
+
+Managed by [Frog](https://github.com/wevm/frog).

+Log papercuts and friction you hit in this repository (tooling, docs, APIs, tests, conventions) with `frog log`, and run `frog list` first so you don't re-report something already known. Only repo-level friction belongs in `.agents/friction-log/`, not global, system, or agent-harness friction. If `frog` is missing, install the pinned release instead of piping the installer into a shell (pick the asset matching your platform from https://github.com/wevm/frog/releases/tag/frog@1.1.0):
+
+```sh
+ver=1.1.0
+asset=frog-linux-x64-glibc-baseline.gz
+curl -fsSLO "https://github.com/wevm/frog/releases/download/frog@$ver/$asset"
+curl -fsSL "https://github.com/wevm/frog/releases/download/frog@$ver/SHA256SUMS" | grep "$asset" | sha256sum -c -
+gunzip -c "$asset" > ~/.local/bin/frog && chmod +x ~/.local/bin/frog
