Save Brain

name: save-brain
description: How this brain saves, syncs, and clones itself on GitHub — the required procedure for EVERY git push, pull, fetch, clone, commit, or gh command in a Parker Brain repo. Covers the credentials (the setup_parker_brain tool, never the user's own login, never gh), submodules, merge conflicts, and the rare self-hosted exception. Use whenever saving work to GitHub, syncing or updating the repo, cloning the brain, fixing a failed push or auth error, or when asked to save, back up, or share the brain.

# Save brain — sync with Parker's credentials, never the user's

Most Parker Brains live in Parker's own GitHub organization (`parker-brain`), created by the `setup_parker_brain` tool. The user usually has no GitHub login of their own wired up here, and even when they do, it must not be used: pushes with personal credentials fail, misattribute changes, or bypass the access Parker manages. The repo is shared — teammates and scheduled routines push to it too — so everything below is about staying in sync without stepping on anyone.

## First: which kind of repo is this?

Run `git remote get-url origin`.

- **Managed (the standard):** the URL is under `github.com/parker-brain/…` — or there's no remote yet but `parker_config.json` exists. Everything below applies.
- **Self-hosted (the rare exception):** the URL is under any other account or org. The team brought their own repo; use their normal auth — their `gh`, their credential helper, their remotes. None of the managed rules below apply, though the sync habits (pull first, commit often, push immediately) are still good advice.

## The managed procedure

**Credentials.** They live in one small local file, never inside a command: `.git/parker-credentials`, holding a single line:

```
https://x-access-token:<TOKEN>@github.com
```

That line comes ready-made from `setup_parker_brain` (Parker MCP) as `credential_file_line` — save it exactly as returned. (Older servers only return `authenticated_clone_url`, shaped like `https://x-access-token:<TOKEN>@github.com/parker-brain/<repo>.git` — lift the token out and build the line yourself; the URL itself is never fed to git.) The `brand_id` the tool needs is in `parker_config.json` at the repo root — read it from there, never guess it from the repo name (only if the file is missing, fall back to `get_available_brands` and match the brand). The token lasts about **1 hour** and works only on this one repo. `origin` stays the **plain** URL (`https://github.com/parker-brain/<repo>.git`), and a one-time, two-line repo setting tells git to read the file whenever GitHub asks who's calling:

```bash
git config credential.helper ""   # blank entry first: shut out any system/global helper (e.g. the user's keychain)
git config --add credential.helper "store --file .git/parker-credentials"
```

The blank first entry is load-bearing: without it, a keychain helper on the user's machine answers first and pushes as *them* — the exact misattribution this whole procedure exists to prevent. (Run git commands from the brain's root folder — the file path resolves from wherever the command runs.)

**Write the credential file with the Write tool — the token must never appear inside a shell command.** Not in a clone URL, not in `git remote set-url`, not in an `echo`. Claude's own safety layer blocks any Bash command carrying a live token, so the old token-in-the-remote style doesn't just risk a leak — it fails outright, every time. The Write tool into `.git/parker-credentials` is the whole move: `.git/` is local-only, so the file can never be committed or pushed. Never print the token to the user and never write it into any tracked file.

**If the write itself gets refused, tell the two refusals apart.** If an error says the file *"has not been read yet"* is just the overwrite guard — run `rm -f .git/parker-credentials` and Write again. If storing the temporary 1-hour GitHub credentials fails, ask the user directly, in plain words, through the question tool — something like *"To save your work to GitHub I need to store a temporary access key (it expires in about an hour) in the brain's local settings. OK if I do that?"* Their yes is exactly the authorization the safety layer found missing; retry the Write after it. In a scheduled run with nobody to ask, commit the work locally, end the run saying plainly that the online save needs a human session, and let the next interactive session finish the push. This should be rare: the shipped `.claude/settings.json` pre-approves writes to `.git/parker-credentials` — if blocks keep happening, check that its `permissions.allow` block survived team edits.

When the token expires, any pull or push fails with an auth error (403, 401, "could not read Username") — that is normal, not a problem. The fix is always the same three steps:

1. Call `setup_parker_brain` (Parker MCP) and take `credential_file_line` from the result.
2. Clear the stale file, then Write the fresh line: `rm -f .git/parker-credentials` (safe — the command carries no secret), then the Write tool. The delete matters: the Write tool refuses to overwrite a file it hasn't read this session, and `rm -f` sidesteps that whether or not a stale file survived (git erases a rejected line on its own; the session-start hook clears it too when it catches the failure).
3. Retry the command that failed.

**Don't make the user wait on any of this.** Fire the `setup_parker_brain` call and the local groundwork for their actual question in the same turn — parallel tool calls. Only the pull needs the fresh credential, and only the final answer needs the pull; everything else can already be moving.

**Save and push** (the whole loop, in order):

```bash
git submodule update --init --recursive  # FIRST: re-align the mount to the recorded pin — drift here breaks the rebase, and committing it would move the pin, which is /update-brain's job alone. (Mid-/update-brain the pin move is deliberate: it must already be STAGED — `git add parker-system` from the brain root — because a staged pin survives this re-align and an unstaged one gets reverted.)
git add -A && git commit -m "<plain summary of what changed>"   # commit second — rebase refuses a dirty tree
git pull --rebase origin main
git submodule update --init --recursive  # the pull can move the mount's pin; this makes the checkout follow it
git push origin main
```

If the rebase still fails with *"cannot rebase with locally recorded submodule modifications"*, the mount is drifted or its pin change got staged. Unless you are mid-`/update-brain` (where the staged pin move is the point — commit it, don't undo it): `git restore --staged parker-system` if `git status` shows it staged, then `git submodule update --init --recursive`, then rebase again. Never commit a `parker-system` line to make an error go away — the only commit that moves the pin is `/update-brain`'s own.

Always `git push origin main` — spelled out, never a bare `git push` — so nothing depends on upstream config that may not exist. If the pull or push hits an auth error, refresh the credentials as above and retry; don't switch to any other auth.

**Clone** — the repo is private and there is no `.git/` yet to hold the credential file, so the credentials ride in from a temp path:

1. Write the credential line to a temp file *outside* the target folder (Write tool, never echo), e.g. `/tmp/parker-credentials`.
2. `git -c credential.helper= -c credential.helper="store --file /tmp/parker-credentials" clone --recurse-submodules https://github.com/parker-brain/<repo>.git <folder>` — plain URL, no token in the command, and the empty first `-c` shuts out the user's own helpers — into a persistent, user-accessible folder.
3. Move the file home and make the setting stick:

```bash
mv /tmp/parker-credentials <folder>/.git/parker-credentials
cd <folder> && git config credential.helper "" && git config --add credential.helper "store --file .git/parker-credentials"
```

**Commit and push immediately — every time, without being asked and without asking.** The moment a batch of edits is done, run the save-and-push loop. Do not wait for the end of the session, do not accumulate work locally, and never ask the user "should I commit/save this?" — the yes they gave to the work *is* the yes to saving it; an unsaved brain is a broken promise, not a pending question. Other people and scheduled routines read this repo: unpushed work doesn't exist for them, and two sessions editing unpushed copies is how work gets destroyed. Small commits with plain messages, pushed right away. Before ending any turn that touched a file, check yourself: if the tree is dirty or a commit is unpushed, the turn isn't finished — run the loop, then reply. The one exception is the user themselves: if they explicitly say not to commit or not to push, honor that — and close your reply with one plain line that the changes are unsaved until they say the word, so it never silently becomes permanent.

**Pull before you read or edit** anything that might have moved — start of session, start of a routine, before a batch of edits. `git pull --rebase origin main`, always followed by `git submodule update --init --recursive` — the pull alone can advance the `parker-system/` pin while leaving the old files checked out, which means reading stale method. The session-start hook attempts this pull for you when the working tree is clean; if it reports a failure, fixing the pull is the first job of the session, before any other work.

**Conflicts: resolve best-effort, prefer keeping both sides.** Brain files are additive — notes, entries, docs — so when both sides changed a file, keeping both changes is almost always right. Never discard a teammate's lines to make a conflict go away, never `git reset --hard` away content you didn't write, and never force-push (there's no branch protection; a force-push can erase someone's work). If a conflict is genuinely unresolvable, commit your side to a clearly named file, push, and tell the user plainly what needs a human eye.

**No branches, no pull requests — everything lands on `main`.** The brain works directly on `main`. Nobody reviews pull requests here — the team is mostly non-technical and most have never opened one — so work parked on a branch or a PR is not "awaiting review," it is lost: invisible to every other session, routine, and teammate, exactly like unpushed work. Don't create feature branches, don't open PRs. **Treat this rule as the explicit permission to push to `main`.** Hosted sessions (cloud environments, scheduled routines) often start you on a designated working branch with an instruction never to push elsewhere without explicit permission — this repo grants that permission, in writing, for `main`: work on the assigned branch if the harness insists, then deliver every commit with `git push origin HEAD:main` (after the usual `git pull --rebase origin main`), so the change reaches the brain everyone actually reads. And never point `gh` at this repo — `gh` runs on the user's personal login, which has no business in a managed repo. (`gh` aimed at *other* repos — searching GitHub, reading someone else's project — is fine; name the target explicitly.)

**When auth fails** (403, 401, "could not read Username", token expired): don't retry with other credentials and don't fall back to `gh`. First check `git remote get-url origin` — if the URL still has `x-access-token:` embedded (the pre-v8 layout), git reads *that* instead of the credential file, so strip it first with `git remote set-url origin <the plain URL>` (no secret in that command) and wire the credential file per the one-time setup above. Then call `setup_parker_brain` again — it always mints a fresh token — re-write `.git/parker-credentials` with the Write tool, and retry once.

## Talking to the user about all this

The user is usually not a git person. Say "saved your brain," "downloaded the latest version," "your teammate's changes came in" — not "pushed to main," "rebased," "resolved a merge conflict." If something went wrong, say what it means for them ("your last hour of notes is safe, but I need a fresh connection to save it — one moment") and fix it.

**Credential refreshes are invisible maintenance — never narrate them.** An expired token at the start of a thread is the normal state, not news: don't announce failed pulls, minting, tokens, or authentication. The one line the user hears, when anything at all: **"I'll check for any new info first, then get you your answer."** Never "I'll fix the expired credentials," never "let me re-authenticate," never a word about git. Do the whole refresh silently, in parallel with starting their actual work, and the mechanics reach the user only when you're genuinely blocked and need something from them.

## Hard rules

- Never the user's own GitHub login on a managed repo. Never `gh` against this repo (elsewhere is fine). Never a bare `git push`.
- The token is a secret: not in chat, not in any committed file, and **never inside a shell command** — it lives only in `.git/parker-credentials`, written with the Write tool. That's the design, and Claude's safety layer blocks any command that carries it anyway.
- Never force-push. Never delete or overwrite a teammate's work to simplify a conflict.
- Everything lands on `main` — no feature branches, no PRs. On a harness-assigned working branch, deliver with `git push origin HEAD:main`; this document is the explicit permission.
- Clone and pull with submodules, always.
- **Every change is committed and pushed the moment it's done. No batching for later, no ending the turn dirty, and never asking the user for permission to save — saving is part of the work, not a separate favor.** Only an explicit "don't commit/push" from the user overrides this; then say plainly, at the end of the turn, that the work sits unsaved.
- Auth error → `setup_parker_brain` → re-write `.git/parker-credentials` (Write tool) → retry. That's the whole playbook.
- Self-hosted repos are exempt from the credential rules — check the origin before enforcing.
