DonchitosandClaude Opus 5 d05699707f Release 1.1.0 — one config file, and a process weight you choose

`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.

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

{
  "tool_name": "Bash",
  "tool_input": {
    "command": "git commit -m 'feat: add player health system'",
    "description": "Commit changes with message",
    "timeout": 120000
  }
}

PreToolUse: Write

{
  "tool_name": "Write",
  "tool_input": {
    "file_path": "src/gameplay/health.gd",
    "content": "extends Node\n..."
  }
}

PreToolUse: Edit

{
  "tool_name": "Edit",
  "tool_input": {
    "file_path": "src/gameplay/health.gd",
    "old_string": "var health = 100",
    "new_string": "var health: int = 100"
  }
}

PreToolUse: Read

{
  "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

{
  "tool_name": "Write",
  "tool_input": {
    "file_path": "assets/data/enemy_stats.json",
    "content": "{\"goblin\": {\"health\": 50}}"
  },
  "tool_output": "File written successfully"
}

PostToolUse: Edit

{
  "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).

{
  "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.
