+- Read the full workflow thread: \`nerve thread show ${threadId}\`
+- Optional workspace tone: \`cat ${nerveRoot}/CONVENTIONS.md\`
+
+## Find repo and issue markers
+
+In the thread, locate \`---SOLVE_ISSUE_PARSE---\` and \`---SOLVE_ISSUE_REPO---\`. From them you need:
+
+- Issue **number** and **title** (from PARSE; title for the branch slug)
+- Repo checkout **path** (from REPO \`path\`) — this is your working copy; your shell cwd should be this directory.
+
+## Steps (in order)
+
+1. \`cd\` to the repo **path** from SOLVE_ISSUE_REPO.
+2. Run \`git status\`. There should be **uncommitted** changes from implement. If the tree is clean with nothing to commit, set **committed** to false and explain.
+3. Create a feature branch (do not work on the default branch directly):
+   - Name: \`fix/<number>-<short-slug>\` for fixes, or \`feat/<number>-<short-slug>\` if the issue is clearly a feature.
+   - **number** from SOLVE_ISSUE_PARSE.
+   - **slug**: lowercase, hyphens only, short (from issue title words).
+   - Example: \`git checkout -b fix/42-auth-timeout\`
+4. \`git add -A\`
+5. Write a **conventional commit** message (e.g. \`fix(scope): summary\` or \`feat(scope): summary\`) describing **what** changed and **why**, using the thread (plan + implement context).
+6. \`git commit -m "<message>"\` — use a single \`-m\` for a one-line message, or multiple \`-m\` for body paragraphs if needed.
+7. \`git push -u origin <branch-name>\`
+
+**committed=true** only if you created the branch, committed successfully, and **push** succeeded.

 ## Steps (in order)

+1. \`cd\` to the **repo \`path\`**. Run \`git rev-parse --abbrev-ref HEAD\` to get the current branch name. The **committer** step should already have pushed this branch; run \`git push -u origin <that-branch>\` only if the branch is not yet on the remote.
+2. Choose a **PR title** that reflects the real change (not a generic \`fix: issue #N\`): derive it from the issue title, plan, and thread summary (keep it concise; Conventional Commits style is fine, e.g. \`fix(auth): handle session expiry\`).
 3. Write a **PR body** in Markdown with exactly these sections, in this order, each with a \`##\` heading (fill with concise content based on the thread: plan, implement, review, test):
    - **## What** — one short paragraph: what this PR does
    - **## Why** — one short paragraph: motivation / issue
    - **## Changes** — bullet list of notable changes
    - **## Ref** — the issue link above
 4. Create the PR with **tea** (not curl/fetch to Gitea):
-   - \`tea pr create --repo <owner>/<repo> --base <defaultBranch> --head <branch> --title "fix: issue #<number>" --body <your markdown body>\`
+   - \`tea pr create --repo <owner>/<repo> --base <defaultBranch> --head <branch> --title "<your meaningful title>" --body <your markdown body>\`
    - You may use a heredoc or a temp file for \`--body\` if the shell requires it; keep the four sections in the body.
 5. Confirm the PR was created (tea prints a URL or PR number in typical setups).
