Phase 2 of plans/autonomous-survival-bot-prd.md. Establishes the
composable skill contract from PRD §5.2 and ports three reference
skills so future phases can layer survival behaviour on top instead of
adding more ad-hoc branches to reflex.js.
New: runtime/skills/
- index.js: skill registry + runSkill(id, ctx, args) wrapper. Enforces
preconditions, hard timeout, normalises {ok, code, detail, worldDelta}
on every result, runs validate() and calls recover() on failure.
Stable failure codes live in RUNNER_CODES (unknown_skill,
precondition_failed, timeout, threw, validation_failed, done).
- groups.js: registry-derived item/block sets — logs/planks/sticks/beds
derived by suffix; foods intersects a curated allowlist with the live
bot.registry; axes/pickaxes/swords scoped to whatever the connected
server's item table actually ships. Empty set instead of throwing on
missing registry, so skills can emit code:"unsupported_version".
- chop-logs.js: gather.logs reference skill (wraps chopNearestTree).
- eat.js: survive.eat (wraps eatBestFood, preconditions check carrying
edible food from the registry-derived set).
- wander.js: explore.wander (wraps wander).
- contract.test.js + groups.test.js: 14 tests covering precondition
gating, timeout firing recover(), execute exceptions, validate
flipping ok→false, dynamic group filtering across mock registries.
package.json: `npm test` runs the new contract + groups suites.
docs/runtime.md: documents the skill contract, runner, dynamic groups
and the reference skills.
Reflex.js still calls actions.js directly — wiring the scheduler to
runSkill() lands in later phases when the survival curriculum kicks in.
