- MagicalObject: internal #health and #maxHealth now Health type
- HealingObject: constructor, create, and heal use Health value object
- MagicalWeapon: constructor, create, and use use Health value object
- DamageDealer and Healer interfaces: health: number -> health: Health
- magical-objects.spec.ts: all assertions use .health.value
- Run npm run checks: 0 errors, 70 tests passing
Add custom ESLint rule that warns when class properties or constructor
parameters use primitive types (number, string, boolean) where a value
object exists in src/value-objects/.
The rule auto-discovers value objects from the directory and maps
property names (e.g. 'health' → 'Health') to suggest the correct type.
Found 4 warnings on the codebase:
- MagicalObject.ts: #health: number property
- MagicalObject.ts: health: number constructor param
- MagicalWeapon.ts: health: number constructor param
- HealingObject.ts: health: number constructor param
- Create src/magical-objects/magical-object-types.ts with DamageDealer
and Healer interfaces
- MagicalWeapon implements DamageDealer
- HealingObject implements Healer
- Character depends on interfaces instead of concrete classes
- MagicalWeapon: fixed damage, owner-only, self-destructs at 0 HP
- HealingObject: heals characters up to both caps, self-destructs at 0 HP
- 18 fast-check properties covering rules and invariants
- Allium spec with entities, rules, and invariants
- Character.createWithHealthAndStatus factory method for status-aware creation
- dealDamage returns new Character instead of mutating in-place
- SelfDamageForbidden uses reference equality (this === target)
- Negative damage throws at the boundary
- Removed duplicate Health.maxHealthForLevel (Level.ts is source of truth)
- Allium spec uses max(0, ...) for health floor precision
- New property: NegativeDamageForbidden (11 total properties)
- Allium spec: damage-and-health.allium
- 5 fast-check properties: damage reduces health, health non-negative,
death at zero, self-damage forbidden, dead cannot take damage
- Character.createWithHealth factory for testing with arbitrary health
- Character.dealDamage(target, damage) method
Registers a /clear slash command as a project-local extension.
Prompts for a transcript name (spaces → dashes), exports the full
session HTML (with in-memory state) to transcripts/<name>.html,
then starts a new session with parent tracking.
- Clarify 'value objects over primitives' is reactive, not anticipatory
- Mark the Step 3 example as aspirational domain shape, not per-story template
- Add 'What to skip per story' trap table with concrete boundaries
- Add litmus test: 'point to a failing property or don't write it'
- Level value object (1..10, level-capped health)
- Health value object (non-negative, pure sub/add)
- Status discriminated union (alive | dead)
- Character entity with private constructor and static factory
- 9 fast-check properties covering creation invariants
- Allium spec with entities, rules, and invariants
Add the user-story-conversation Pi skill following Ron Jeffries'
Card, Conversation, Confirmation mantra enhanced with Matt Wynne's
Example Mapping.
The skill guides users through six steps:
1. Card — user story
2. Conversation — Example Mapping (Rules, Examples, Questions, Answers)
3. Allium Spec — formal behavioural specification
4. fast-check Properties — executable verification
5. TypeScript ADTs — value objects and discriminated unions
6. Confirmation — verify all properties pass
Also update AGENTS.md with workflow guidance and add the new skill
to the Allium routing table. Add fast-check as a dependency.
Install Allium skills (allium, elicit, distill, propagate, tend, weed)
from the pi-allium-port, with corrected symlinks for upstream content.
Add juxt/allium as a git submodule for language reference materials.
Allium CLI v3.0.5 is already installed via Homebrew.
