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.

estimate Estimate task effort from complexity, dependencies, velocity, risk. Structured estimate with confidence levels. [task-description] true Read, Glob, Grep sonnet

Phase 1: Understand the Task

Read the task description from the argument. If the description is too vague to estimate meaningfully, ask for clarification before proceeding.

Read CLAUDE.md for project context: tech stack, coding standards, architectural patterns, and any estimation guidelines.

Read relevant design documents from design/gdd/ if the task relates to a documented feature or system.


Phase 2: Scan Affected Code

Identify files and modules that would need to change:

  • Assess complexity (size, dependency count, cyclomatic complexity)
  • Identify integration points with other systems
  • Check for existing test coverage in the affected areas
  • Read past sprint data from production/sprints/ for similar completed tasks and historical velocity

Phase 3: Analyze Complexity Factors

Code Complexity:

  • Lines of code in affected files
  • Number of dependencies and coupling level
  • Whether this touches core/engine code vs leaf/feature code
  • Whether existing patterns can be followed or new patterns are needed

Scope:

  • Number of systems touched
  • New code vs modification of existing code
  • Amount of new test coverage required
  • Data migration or configuration changes needed

Risk:

  • New technology or unfamiliar libraries
  • Unclear or ambiguous requirements
  • Dependencies on unfinished work
  • Cross-system integration complexity
  • Performance sensitivity

Phase 4: Generate the Estimate

## Task Estimate: [Task Name]
Generated: [Date]

### Task Description
[Restate the task clearly in 1-2 sentences]

### Complexity Assessment

| Factor | Assessment | Notes |
|--------|-----------|-------|
| Systems affected | [List] | [Core, gameplay, UI, etc.] |
| Files likely modified | [Count] | [Key files listed below] |
| New code vs modification | [Ratio] | |
| Integration points | [Count] | [Which systems interact] |
| Test coverage needed | [Low / Medium / High] | |
| Existing patterns available | [Yes / Partial / No] | |

**Key files likely affected:**
- `[path/to/file1]` -- [what changes here]

### Effort Estimate

| Scenario | Days | Assumption |
|----------|------|------------|
| Optimistic | [X] | Everything goes right, no surprises |
| Expected | [Y] | Normal pace, minor issues, one round of review |
| Pessimistic | [Z] | Significant unknowns surface, blocked for a day |

**Recommended budget: [Y days]**

### Confidence: [High / Medium / Low]

[Explain which factors drive the confidence level for this specific task.]

### Risk Factors

| Risk | Likelihood | Impact | Mitigation |
|------|-----------|--------|------------|

### Dependencies

| Dependency | Status | Impact if Delayed |
|-----------|--------|-------------------|

### Suggested Breakdown

| # | Sub-task | Estimate | Notes |
|---|----------|----------|-------|
| 1 | [Research / spike] | [X days] | |
| 2 | [Core implementation] | [X days] | |
| 3 | [Testing and validation] | [X days] | |
| | **Total** | **[Y days]** | |

### Notes and Assumptions
- [Key assumption that affects the estimate]
- [Any caveats about scope boundaries]

Output the estimate with a brief summary: recommended budget, confidence level, and the single biggest risk factor.

This skill is read-only — no files are written. Verdict: COMPLETE — estimate generated.


Phase 5: Next Steps

  • If confidence is Low: recommend a time-boxed spike (/prototype) before committing.
  • If the task is > 10 days: recommend breaking it into smaller stories via /create-stories.
  • To schedule the task: run /sprint-plan update to add it to the next sprint.

Guidelines

  • Always give a range (optimistic / expected / pessimistic), never a single number
  • The recommended budget should be the expected estimate, not the optimistic one
  • Round to half-day increments — estimating in hours implies false precision for tasks longer than a day
  • Do not pad estimates silently — call out risk explicitly so the team can decide
