+## Sibling repo mirrors
+
+If a project works alongside sibling repos on the same self-hosted Git host, Claude can be given
+read-only, auto-refreshing local clones of them to grep for prior art — plus, optionally, the
+`gitea` MCP server for their issues and PRs. This is **opt-in per project** and driven entirely by
+one manifest, `.ddev/claude-refs.txt`; projects without that file see no change at all.
+
+`.ddev/claude-refs.txt` is **local by default**: the add-on's [managed git-exclude
+block](#keeping-add-on-files-out-of-git) ignores it, since it typically names a LAN-only Git host,
+a bot token, and mirrors specific to one person's sandbox. A project that wants the manifest shared
+with the rest of the team can still track it with `git add -f .ddev/claude-refs.txt`.
+
+### Manifest: `.ddev/claude-refs.txt`
+
+```
+# Settings: one per line, starting with @
+@host  git.example.com                       # required
+@user  claude-ro                             # bot account; with @token, drives git credentials
+@token ~/.gitea-ro-token                     # default; 0600 file in the sandbox home, never committed
+@depth 50                                    # default
+@mcp   gitea https://mcp.example.com/mcp     # optional: name + URL, registered with the token as Bearer
+
+# Mirrors: <dir-name> <owner/repo> <description, rest of line, becomes the README row>
+sibling-api   org/sibling-api   Go service this project talks to over HTTP.
+shared-lib    org/shared-lib    Shared component library, imported as a dependency.
+```
+
+Inline `#` comments are only allowed on setting lines, after all the values the setting reads.
+Keep them off mirror lines, or they end up in the description.
+
+Environment overrides, mainly for testing: `CLAUDE_REFS_MANIFEST`, `CLAUDE_REFS_HOME`,
+`CLAUDE_REFS_MAX_AGE` (seconds), `CLAUDE_REFS_TIMEOUT` (seconds per clone or fetch), and
+`CLAUDE_REFS_DETACHED` (set by `install.sh`; sends output to `refs/.sync.log`).
+
+### What happens once a project has a manifest
+
+- On `ddev start` and on every `ddev claude`, `install.sh` runs the sync in the background
+  (`setsid nohup`) so neither command waits on the network. A stamp file throttles real syncs to
+  at most one every 6h (`CLAUDE_REFS_MAX_AGE`), written only after a fully successful run, so a
+  failure retries next launch. If the Git host is unreachable, the sync logs a line and exits
+  cleanly rather than failing `ddev start`.
+- Mirrors are shallow (`--depth 50 --single-branch` by default), live under
+  `.ddev/claude-code/home/refs/` (gitignored, survives `ddev restart`), and are **throwaway**:
+  every sync hard-resets them to the remote's current state, so local changes are lost and nothing
+  is ever merged. A directory that drops out of the manifest is left in place with a warning
+  rather than deleted.
+- An entry whose repo resolves to the project's own `origin` is skipped, so the project never ends
+  up with a second, stale copy of itself.
+- `refs/README.md` is regenerated from the manifest on every sync — descriptions come from the
+  manifest, so the table can't drift from what's on disk.
+- The bot account's credential file and git config are rewritten from the manifest on every run,
+  so a renamed bot account heals itself on the next `ddev claude` instead of failing silently.
+- Run `ddev claude-refs` to sync immediately instead of waiting for the throttle; inside a Claude
+  session, running `.ddev/claude-code/refs-sync.sh --force` does the same and is already on the
+  permission allowlist.
+- If `@mcp` is set, the MCP server is registered once at user scope (`claude mcp add --scope
+  user`), and required permission-allowlist entries are added once — both idempotently, so re-runs
+  never duplicate them.
+
+Access control (which repos the mirrors can see) stays entirely in the Git host: the bot account's
+collaborator access decides what's visible. The manifest only names repos; it grants nothing by
+itself.
+
+### Adopting in a project
+
+1. On the Git host, add the bot account as a **read-only** collaborator to each sibling repo.
+2. Create `.ddev/claude-refs.txt` with `@host`, `@user`, and the mirrors you want. It stays local
+   unless you `git add -f` it (see above).
+3. Put the bot's token at `.ddev/claude-code/home/.gitea-ro-token`, mode `0600` (matches the
+   manifest's default `@token ~/.gitea-ro-token`; never commit it).
+4. `ddev restart`, then check `.ddev/claude-code/home/refs/.sync.log` after a minute or so.
+5. Paste this into the project's `CLAUDE.md`, adding a sentence about the most relevant sibling:
+
+   ```markdown
+   ## Sibling repos
+
+   Read-only shallow clones of sibling projects live in `.ddev/claude-code/home/refs/`
+   (gitignored, declared in `.ddev/claude-refs.txt`). Grep them for prior art before
+   re-deriving a solution; `refs/README.md` says what each one is. They are reference
+   material: never commit or push from them. They sync in the background at most every
+   6h; run `ddev claude-refs` before trusting anything time-sensitive.
+   ```
+
+The container still needs to resolve and reach the Git host (and the MCP host, if used).

-## Notes
+## Keeping add-on files out of git
 
+Every artifact the add-on drops into a project — `.ddev/claude-code/`, `.ddev/codex-cli/`, the
+`commands/web/*` wrappers, `.ddev/config.codex-claude.yaml`, `.ddev/addon-metadata/ddev-codex-claude-cli`,
+`.ddev/plans`, and `.ddev/claude-refs.txt` — should stay out of the project's git history.
+
+`.ddev/claude-code/git-exclude.sh` maintains a marker-delimited block for this in the project's
+`.git/info/exclude` (not `.gitignore`): a per-clone file that every git process honours, including
+git run from the host, regardless of `$HOME` or container config. `install.sh` runs it on every
+`ddev start` and every `ddev claude` (and the codex installer runs the same script too), so the
+block always matches the add-on's current file list — nothing to copy or keep in sync by hand.
+
+Content outside the `>>> ddev-codex-claude-cli >>>` / `<<< ddev-codex-claude-cli <<<` markers is
+left untouched; only the block between them is rewritten. Personal patterns (`.DS_Store`, `.idea`,
+`CLAUDE.md`, …) are not part of this block — they belong in your own `~/.gitignore_global`, wired
+up via `core.excludesfile` as described below, since whether a given project tracks its own
+`CLAUDE.md` is not the add-on's call.
+
+- if the container home has `.gitignore_global` (typically from host `~/.ddev/homeadditions/.gitignore_global`), it is copied into each project-local CLI `HOME` on first bootstrap; git's `core.excludesfile` is pointed at that project-local copy — this only affects git run *inside* the container, which is why the add-on's own artifacts use the `.git/info/exclude` block instead
 - the first `ddev codex` in a project can take some time because it downloads the Codex CLI binary; later runs reuse `.ddev/codex-cli/bin/codex`
 - the first `ddev start` after installing the add-on can take some time because it downloads Claude Code; later starts reuse `.ddev/claude-code/home/.local/bin/claude`
-- if the container home has `.gitignore_global` (typically from host `~/.ddev/homeadditions/.gitignore_global`), it is copied into each project-local CLI `HOME` on first bootstrap; git's `core.excludesfile` is pointed at that project-local copy
-- if you do not want add-on or CLI runtime files in your repository, ignore them in git, for example:
 
-      /.ddev/addon-metadata/ddev-codex-claude-cli
+Removing the add-on deletes `.ddev/codex-cli/` and `.ddev/claude-code/` as well (local auth, config, and CLI binaries). Back up those directories first if you need to keep them. The `.git/info/exclude` block is left in place; an orphaned entry for a path that no longer exists is harmless.
-      /.ddev/config.codex-cli.yaml
-      /.ddev/config.claude-code.yaml
-      /.ddev/commands/web/codex
-      /.ddev/commands/web/claude
-      /.ddev/commands/web/claude-swap
-      /.ddev/codex-cli/
-      /.ddev/claude-code/
-
-Removing the add-on deletes `.ddev/codex-cli/` and `.ddev/claude-code/` as well (local auth, config, and CLI binaries). Back up those directories first if you need to keep them.
