description: >-
  Portable, safe operating workflow for LLMs working on any Git/forge project:
  issue-first, isolated branch worktrees, no self-review/self-merge, distinct
  author/reviewer profiles, cleanup after merge, and fail-closed behavior.
  Use at the start of any implementation, review, or merge task on a repo.

# LLM Project Workflow

A reusable workflow any LLM can follow to work on any repository safely. Copy
this `skills/llm-project-workflow/` directory into another project unchanged;
adapt only the forge-specific names in [Adapting to a project](#adapting-to-a-project).

The core promise: **an LLM never does unsafe or untracked work.** Every change
is tracked by an issue, isolated in its own worktree, reviewed by a different
identity, and cleaned up only after a real merge.

---

## A. Issue-first rule

**No repository change without a tracking issue.** This includes creating,
editing, deleting, or `chmod`-ing files; docs; scripts; commits; pushes; and PRs.

1. Before any change, confirm a tracking issue exists.
2. If none exists, create one first (title + problem + scope + acceptance).
3. Claim it (assign yourself or apply the `status:in-progress` label) and comment
   that work is starting, including the planned branch name.
4. **If the issue cannot be created or claimed, stop.** Do not touch files.

Reading the repo, running read-only status/`git log`, and creating/claiming the
issue itself are allowed from the orchestration checkout without a prior issue.

## B. Isolated worktree rule

**Never implement or review in the main checkout.** The main checkout is for
orchestration and status only (issue creation, `git status`, creating worktrees).

- Each issue gets its own branch worktree under an ignored `branches/` directory.
- Review work uses a **separate** review worktree, never the author's folder.
- Dirty work in one branch folder must not block starting another issue.
- No LLM may edit another issue's worktree unless explicitly assigned to it.
- Branch folders are removed only after the PR is merged/closed **and** cleanup
  is explicitly part of the task.

Every implementation branch **must include its issue number** so it is
traceable end to end: **issue → branch → worktree folder → PR → cleanup.**

Allowed implementation patterns:

- `fix/issue-123-short-description`
- `feat/issue-123-short-description`
- `docs/issue-123-short-description`
- `chore/issue-123-short-description`

Review-only branches:

- `review/pr-456-short-description`

Use a filesystem-safe folder under `branches/` by replacing slashes with
hyphens, for example `branches/fix-issue-123-short-description`.

`scripts/worktree-start` **enforces** this: it rejects an implementation branch
that does not match `(fix|feat|docs|chore)/issue-<number>-…` (or a
`review/pr-<number>-…` branch), unless `--allow-unlinked` is passed. Traceability
is maintained by:

- the branch name (contains the issue number),
- a claim comment on the issue, e.g.
  `Claimed. Branch: fix/issue-123-short-description. Worktree: branches/fix-issue-123-short-description.`,
- the PR body — `Closes #123` when the PR should close the issue, `Refs #123`
  when related but not closing,
- cleanup after merge — remove the remote branch, local branch, and the issue
  worktree folder, and drop `status:in-progress`.

For projects using `Gitea-Tools` helpers:

```bash
scripts/worktree-start fix/issue-123-example      # → branches/fix-issue-123-example
scripts/worktree-review fix/issue-123-example     # → branches/review-fix-issue-123-example (detached)
scripts/worktree-clean  --delete-branch fix/issue-123-example
```

Manual equivalent:

```bash
git fetch <remote> --prune
git worktree add -b fix/issue-123-example branches/fix-issue-123-example <remote>/master
cd branches/fix-issue-123-example
```

`venv/` and similar are not copied into new worktrees — run checks with a known
interpreter path, or create a venv inside the branch folder.

## C. Identity and profile safety

- Use canonical execution profiles where available; the profile is the role, not
  the LLM. A task selects a profile; a profile is not permanently assigned.
- **Author and reviewer identities must be distinct.**
- Never place raw tokens/passwords in an LLM/MCP client config. Reference secrets
  by keychain id or environment variable name only. Prefer a single canonical
  config file selected by two env vars, e.g.:
  - `GITEA_MCP_CONFIG` — path to the canonical profiles file
  - `GITEA_MCP_PROFILE` — the profile to activate
- **If the authenticated user equals the PR author, stop** — no self-review, no
  self-merge.

## D. Branch naming

```text
fix/issue-123-short-description
feat/issue-123-short-description
docs/issue-123-short-description
review/pr-456-scope-check
```

Worktree folder = branch with `/` replaced by `-`
(`branches/fix-issue-123-short-description`).

## E. Start-work workflow

1. Verify the orchestration checkout (right repo, clean tree).
2. Fetch/prune: `git fetch <remote> --prune`.
3. Confirm local `master` equals remote `master` (`git rev-list --left-right --count <remote>/master...master` → `0	0`).
4. Create/claim the issue (§A).
5. Create the isolated worktree (§B) from latest remote `master`.
6. Implement the narrow scope only — no unrelated refactors or formatting churn.
7. Add/update focused tests when behavior changes.
8. Run the checks (tests, compile/lint, `git diff --check`, secret scan).
9. Commit with an issue-linked message.
10. Push the branch.
11. Open a PR to `master`.
12. **If you are the author, stop before review/merge.**

## F. Review workflow

1. Use a separate review worktree (`scripts/worktree-review <branch>`), detached.
2. Verify your authenticated identity.
3. Verify the PR author — **you must not be the author.**
4. Verify the worktree is clean.
5. Inspect the full diff; confirm scope matches the linked issue; flag unrelated files.
6. Run the tests.
7. **Do not merge if checks fail. Do not merge if the reviewer is the author.**

## G. Merge / cleanup workflow

Only an eligible (non-author) reviewer merges. After a real merge:

1. Confirm remote `master` actually contains the merge commit.
2. Close/release the issue; remove `status:in-progress` if used.
3. Delete the remote branch.
4. Remove the local branch.
5. Remove the branch worktree folder (`scripts/worktree-clean --delete-branch <branch>`).
6. Fetch/prune.
7. Confirm the main checkout is clean and current (`0	0` vs remote).

Never run cleanup before the merge is confirmed on remote `master`.

## H. Fail-closed cases

**Stop and report — take no mutating action — if:**

- No issue exists and one cannot be created.
- Worktree state is unclear or unexpected.
- Branch/PR state conflicts with the prompt (e.g. prompt says "merged" but it is not).
- A PR is closed but not merged.
- Local `master` is ahead of remote unexpectedly.
- The authenticated user is the PR author (for review/merge).
- Secrets/tokens appear in the diff.
- Tests fail.
- A cleanup step would delete unmerged work.

When in doubt, stop and surface the discrepancy; do not guess or work around a gate.

## I. Recovery patterns

- **Dirty worktree from another issue:** do not touch it. Start your issue in its
  own new worktree; unrelated dirty work must not block you.
- **Local `master` ahead of remote unexpectedly:** do not push `master`. Confirm
  the commits are preserved on a feature branch (local + remote) first, then
  `git reset --hard <remote>/master` to realign. Never discard commits that are
  not safely pushed elsewhere.
- **PR closed but not merged:** the work is not in mainline. Re-push the branch,
  reopen (or open a replacement) PR, and let an eligible reviewer merge. Do not
  assume "closed" means "merged" — verify remote `master` contains the commits.
- **Branch deleted before merge:** if the commits still exist locally (a branch or
  reflog), re-push them and reopen the PR; otherwise recover via
  `git fsck --lost-found`. Preserve first, then proceed.
- **Unauthorized/untracked file created:** do not commit it. Leave pre-existing
  untracked artifacts (e.g. editor/agent dirs, reports) alone; stage only the
  files your issue names (`git add <files>`, never blind `git add -A`).
- **Preserve commits before a reset:** confirm the target commits are reachable
  from a branch that is pushed to the remote, then reset. Verify with
  `git branch --contains <sha>` and `git log <remote>/<branch>`.

## J. Prompt snippets

Ready-to-copy templates live in [`templates/`](templates/):

- [`start-issue.md`](templates/start-issue.md) — start a new issue.
- [`review-pr.md`](templates/review-pr.md) — review a PR.
- [`merge-pr.md`](templates/merge-pr.md) — merge a PR (eligible reviewer only).
- [`recover-bad-state.md`](templates/recover-bad-state.md) — recover from bad state.
- [`worktree-cleanup.md`](templates/worktree-cleanup.md) — clean up after merge.
- [`release-tag.md`](templates/release-tag.md) — create a release tag.

## Adapting to a project

Replace these project-specific names when copying the skill elsewhere:

| Placeholder | Meaning | Example here |
|-------------|---------|--------------|
| `<remote>` | Git remote for the forge | `prgs` |
| default branch | Integration branch | `master` |
| profile env vars | Canonical config + profile selectors | `GITEA_MCP_CONFIG`, `GITEA_MCP_PROFILE` |
| `branches/` | Ignored worktree directory | `branches/` |
| helper scripts | Worktree helpers | `scripts/worktree-start` / `-review` / `-clean` |

The rules in §A–§I are project-agnostic and should not change.

## Versioning And Tagging

Releases follow SemVer: **`vMAJOR.MINOR.PATCH`** (use **`v0.x.y`** while
unstable). Choose the bump by the largest change since the last tag:

- **PATCH** — bug fixes, docs, tests, wrappers, non-breaking workflow polish.
- **MINOR** — new tools/helpers/config features; backward-compatible behavior.
- **MAJOR** — breaking config/schema/API behavior or a changed MCP contract.

Tags must:

- be created **only from `master`** (the exact commit on remote `master`),
- be created **only after the full test suite passes**,
- be **annotated** tags (`git tag -a`), never lightweight,
- include release notes / a changelog summary referencing the merged PRs/issues.

**Never tag** feature branches, dirty worktrees, unreviewed or self-authored
work, or commits not present on remote `master`.

Release process (see [`templates/release-tag.md`](templates/release-tag.md)):

1. `git fetch <remote> --prune`.
2. Verify local `master` equals remote `master` (`0	0`) and the tree is clean.
3. Run the full test suite; stop on any failure.
4. Inspect merged issues/PRs since the last tag
   (`git log --oneline <last-tag>..<remote>/master`).
5. Choose the version bump.
6. Create the annotated tag on remote `master` with release notes.
7. Push the tag.
8. Create/update release notes if the forge supports it.
