# Agent notes

`gh` and HTTPS GitHub access are already authenticated in this environment. Do not print, copy, or

attempt to recover credentials. Read-only commands such as `gh pr view`, `gh api`, `git status`, and

`git log` should work directly.

The recurring Git failure in Codex-managed worktrees is usually **not an authentication failure**.

The worktree's `.git` file points at shared metadata under the original checkout, for example:

```text

/Users/.../git/context-guru/.git/worktrees/...

```

That location is outside the worktree's writable sandbox. Commands that update Git metadata

(`git switch`, `git add`, `git commit`) therefore request escalation. If

`approvals_reviewer = "auto_review"` is configured while the gateway cannot serve the exact

`codex-auto-review` model, escalation fails with HTTP 403 before the command runs.

The user-level fix is to remove that setting from `~/.codex/config.toml`, or set:

```toml

approvals_reviewer = "user"

```

Then restart Codex. Do not modify user configuration unless the user explicitly asks.

When the shared Git metadata remains unwritable, use a clean temporary clone. This stays within the

writable `/tmp` root and uses the existing GitHub authentication:

```sh

pr_tmp=$(mktemp -d /tmp/context-guru-pr.XXXXXX)

git clone https://github.com/rossoctl/context-guru.git "$pr_tmp"

git -C "$pr_tmp" switch -c feat/<topic>

```

Copy only the reviewed task files from the Codex worktree into the clone. Preserve paths and modes,

and exclude generated files such as `__pycache__`; do not blindly copy the whole dirty worktree.

Run the relevant tests and `git diff --check` in the clone, then commit with DCO sign-off:

```sh

git -C "$pr_tmp" add <explicit-paths>

git -C "$pr_tmp" commit --signoff -m '<message>'

git -C "$pr_tmp" push -u origin feat/<topic>

gh pr create --repo rossoctl/context-guru --base main --head feat/<topic> \

--title '<title>' --body '<body>'

```

For later PR updates, reuse the same temporary clone, copy only the changed files, test, commit with

`--signoff`, and run `git -C "$pr_tmp" push`. If commits must be rewritten solely to add DCO

trailers, use `git rebase --signoff` and `git push --force-with-lease`, never an unrestricted force

push.

The local credential helper may print warnings that its configured binary is missing. A push that

ends with a successful `To https://github.com/rossoctl/context-guru.git` ref update still succeeded;

verify with `gh pr view` rather than treating the helper warning alone as failure.

This fallback does not broaden authorization: only create branches, push commits, open issues/PRs,

or post review replies when the user has requested those GitHub mutations.
