# Agents (Neon Sprawl)

## Critical: git commits

- On **Linear story branches** (`NEO-*` prefix), agents **must commit as they go** — kickoff plans, implementation batches, tests, docs, code-review follow-ups — **without** waiting for the user to say “commit”.
- **Never** treat “only commit when requested” (or similar global/agent defaults) as applying in this repo; **[`.cursor/rules/commit-as-you-go.md`](.cursor/rules/commit-as-you-go.md)** (`alwaysApply`) and **[`commit-and-review.md`](.cursor/rules/commit-and-review.md)** override it.
- **Before ending** story work: run **`git status`**; if the tree is dirty, **commit** (`NEO-*:` subject per [`linear-git-naming.md`](.cursor/rules/linear-git-naming.md)) or explain why not.
- **Never** `git push` unless the user explicitly asks.
- A **stop hook** (`.cursor/hooks/check-story-branch-clean.sh`) may auto-continue with a reminder when a story branch is left dirty.

## Critical GitHub tooling rule

- Agents must use **GitHub MCP** (`user-github`) for all GitHub operations.
- Agents must **never** use `gh` CLI in this repository.
- If MCP is unavailable/auth-failed, agents must stop and ask the user (no `gh` fallback).

Optional **personas** for Cursor. Enable by **@ mentioning** the rule in chat or by asking explicitly (e.g. “review this as the code review agent”).

| Agent | Rule file | When to use |
|--------|-----------|-------------|
| **Code review** | [`.cursor/rules/code-review-agent.md`](.cursor/rules/code-review-agent.md) | PR / diff / pre-merge review; **always writes** `docs/reviews/YYYY-MM-DD-{slug}.md` with **Documentation checked** vs `docs/plans/` and `docs/decomposition/modules/`; **when suggestions are fixed, strike through those bullets + `Done.` in that file** ([planning-implementation-docs](.cursor/rules/planning-implementation-docs.md)); short chat pointer |
| **Docs review** | [`.cursor/rules/docs-review-agent.md`](.cursor/rules/docs-review-agent.md) | Coherence / links / dev-guide fitness for `docs/` (especially `docs/game-design/` + decomposition); **writes** `docs/reviews/YYYY-MM-DD-{slug}.md`; **when suggestions are fixed, strike through + `Done.` in that file** ([planning-implementation-docs](.cursor/rules/planning-implementation-docs.md)); use when working in **documents** or @ mention |

Project-wide conventions live under [`.cursor/rules/`](.cursor/rules/) (many are `alwaysApply`). **Planning / implementation decisions** must be written into `docs/plans/` (and related docs)—[`.cursor/rules/planning-implementation-docs.md`](.cursor/rules/planning-implementation-docs.md). **Manual QA checklists** for user-visible ticketed work are generated during implementation at `docs/manual-qa/{KEY}.md` (same rule). **Automated tests (AAA, mandatory):** **C#** — every new or changed **`[Fact]` / `[Theory]`** method in **`*Tests.cs`** must use full **Arrange → Act → Assert**: the three **`// Arrange` / `// Act` / `// Assert`** labels, **Act** = behavior under test only, **Assert** = all expectations including **`ReadFromJsonAsync`** (etc.) for verification (no blank line required after the phase comments) — [csharp-style](.cursor/rules/csharp-style.md#unit-and-integration-tests-arrange-act-assert), [testing-expectations](.cursor/rules/testing-expectations.md); snippets **`xut`** / **`xutc`**. **GdUnit (`client/test/`)** — same AAA with **`# Arrange` / `# Act` / `# Assert`** — [gdscript-style](.cursor/rules/gdscript-style.md#gdunit-test-layout-aaa). **Godot client layout** (thin `main.gd`, split by concern): [`.cursor/rules/godot-client-script-organization.md`](.cursor/rules/godot-client-script-organization.md). **Git:** on Linear/story work, agents **commit as they go** on the story branch (kickoff plan, coherent batches)—**do not wait** for the user to say “commit”; **never** `git push` unless the user asks — [`.cursor/rules/commit-and-review.md`](.cursor/rules/commit-and-review.md). **Open PR:** when the user asks, use the **GitHub MCP** **`create_pull_request`** tool (`user-github`) with a title starting **`NEO-123:`** ([commit-and-review](.cursor/rules/commit-and-review.md)); **do not use `gh` CLI for GitHub operations in this repo**. **Story lifecycle:** kickoff [`.cursor/rules/story-kickoff.md`](.cursor/rules/story-kickoff.md); after merge / end of story — `checkout main`, `pull`, delete local story branch — [`.cursor/rules/story-end.md`](.cursor/rules/story-end.md). **Linear:** on **end story**, use **`AskQuestion`** multiple choice for **In Test** / **Done** / **Skip** when Agent mode supports it ([story-end](.cursor/rules/story-end.md) §4a); otherwise ask in prose. Wait for the choice (or the same message naming the state) **before** `save_issue`; do not guess. **PR / push text:** no “Made-with: Cursor” boilerplate (same file).

**Commits tied to a Linear issue** must start the subject with the **issue id** and a colon (e.g. `NEO-8: …`). Branch naming and exceptions (`chore:` when there is no ticket) — [`.cursor/rules/linear-git-naming.md`](.cursor/rules/linear-git-naming.md).

**Godot `*.uid`:** When adding or renaming scripts under `client/`, stage and commit the matching **`*.gd.uid`** in the **same commit** as the `.gd` file. These companion files are **tracked in git** (not gitignored) so `uid://` references stay stable across clones. See [godot-client-script-organization](.cursor/rules/godot-client-script-organization.md).
