`project.yaml` at the repo root is now the single source of truth for a project's configuration, replacing `production/stage.txt`, `production/review-mode.txt` and `.claude/docs/technical-preferences.md` (all three still read as a fallback; nothing is force-deleted). **`modes.rigor` — one question instead of six.** `minimal`, `standard` or `full` fronts six knobs: `modes.workflow`, `docs.density`, `qa.level`, `modes.story_granularity`, `modes.review_mode` and `team.size`. It defaults to `minimal`, which is a change from 1.0's behaviour: the heavier tier was measured costing several times more to reach working code without producing a better result, and returning nothing when a fresh developer inherited the project. Pin `modes.rigor: standard` to keep 1.0's process level. Also in this release: - `/settings` to view or change any setting, and `project.local.yaml` for per-developer preferences that should not be committed. - `system_overrides` to hold one system to a higher standard than the rest of the project, and `testing.strict` to set per test type whether missing evidence blocks a story or warns. - A story that changes anything the player sees is not closed until the game has been launched, observed, and a screenshot retained in `production/qa/evidence/`. A parse check is not a run. This holds at every rigor level, including `minimal`, where automated tests are waived but the look is not. - The code root is engine-specific and enforced as such: Godot `src/`, Unity `Assets/`, Unreal `Source/<Module>/`. Two of the three will not build a project laid out any other way. - Migration tooling for existing projects: `.claude/scripts/migrate-v1-config.sh` converts a 1.0 layout, non-destructively by default, with a report to review before `--finalize` deletes anything. - Ask-before-write holds regardless of personal automation settings. Upgrading from 1.0 or earlier: see UPGRADING.md. Full list of changes: CHANGELOG.md.

# Hook Input/Output Schemas
|
|
|
|
This documents the JSON payloads each Claude Code hook receives on stdin for every event type.
|
|
|
|
## PreToolUse
|
|
|
|
Fired before a tool is executed. Can **allow** (exit 0) or **block** (exit 2).
|
|
|
|
### PreToolUse: Bash
|
|
|
|
```json
|
|
{
|
|
"tool_name": "Bash",
|
|
"tool_input": {
|
|
"command": "git commit -m 'feat: add player health system'",
|
|
"description": "Commit changes with message",
|
|
"timeout": 120000
|
|
}
|
|
}
|
|
```
|
|
|
|
### PreToolUse: Write
|
|
|
|
```json
|
|
{
|
|
"tool_name": "Write",
|
|
"tool_input": {
|
|
"file_path": "src/gameplay/health.gd",
|
|
"content": "extends Node\n..."
|
|
}
|
|
}
|
|
```
|
|
|
|
### PreToolUse: Edit
|
|
|
|
```json
|
|
{
|
|
"tool_name": "Edit",
|
|
"tool_input": {
|
|
"file_path": "src/gameplay/health.gd",
|
|
"old_string": "var health = 100",
|
|
"new_string": "var health: int = 100"
|
|
}
|
|
}
|
|
```
|
|
|
|
### PreToolUse: Read
|
|
|
|
```json
|
|
{
|
|
"tool_name": "Read",
|
|
"tool_input": {
|
|
"file_path": "src/gameplay/health.gd"
|
|
}
|
|
}
|
|
```
|
|
|
|
## PostToolUse
|
|
|
|
Fired after a tool completes. **Cannot block** (exit code ignored for blocking). Stderr messages are shown as warnings.
|
|
|
|
### PostToolUse: Write
|
|
|
|
```json
|
|
{
|
|
"tool_name": "Write",
|
|
"tool_input": {
|
|
"file_path": "assets/data/enemy_stats.json",
|
|
"content": "{\"goblin\": {\"health\": 50}}"
|
|
},
|
|
"tool_output": "File written successfully"
|
|
}
|
|
```
|
|
|
|
### PostToolUse: Edit
|
|
|
|
```json
|
|
{
|
|
"tool_name": "Edit",
|
|
"tool_input": {
|
|
"file_path": "assets/data/enemy_stats.json",
|
|
"old_string": "\"health\": 50",
|
|
"new_string": "\"health\": 75"
|
|
},
|
|
"tool_output": "File edited successfully"
|
|
}
|
|
```
|
|
|
|
## SubagentStart
|
|
|
|
Fired when a subagent is spawned via the `Agent` tool (named `Task` before
|
|
Claude Code 2.1.63; `Task` still works as an alias in permission rules and
|
|
`tools:` frontmatter, but the hook payload's `tool_name` is now `Agent`).
|
|
|
|
```json
|
|
{
|
|
"agent_name": "game-designer",
|
|
"model": "sonnet",
|
|
"description": "Design the combat healing mechanic"
|
|
}
|
|
```
|
|
|
|
## SessionStart
|
|
|
|
Fired when a Claude Code session begins. **No stdin input** — the hook just runs and its stdout is shown to Claude as context.
|
|
|
|
## PreCompact
|
|
|
|
Fired before context window compression. **No stdin input** — the hook runs to save state before compression occurs.
|
|
|
|
## Stop
|
|
|
|
Fired when the Claude Code session ends. **No stdin input** — the hook runs for cleanup and logging.
|
|
|
|
## Exit Code Reference
|
|
|
|
| Exit Code | Meaning | Applicable Events |
|
|
|-----------|---------|-------------------|
|
|
| 0 | Allow / Success | All events |
|
|
| 2 | Block (stderr shown to Claude) | PreToolUse only |
|
|
| Other | Treated as error, tool proceeds | All events |
|
|
|
|
## Notes
|
|
|
|
- Hooks receive JSON on **stdin** (pipe). Use `INPUT=$(cat)` to capture.
|
|
- Parse with `jq` if available, fall back to `grep` for cross-platform compatibility.
|
|
- On Windows, `grep -P` (Perl regex) is often unavailable. Use `grep -E` (POSIX extended) instead.
|
|
- Path separators may be `\` on Windows. Normalize with `sed 's|\\|/|g'` when comparing paths.
