Five concrete patterns from Voyager and Mindcraft, applied in our shape
without abandoning the git-as-evolution-substrate that makes pepa
distinct. Plus a first multi-agent surface so two bots from the same
repo can share intent.
1. runtime/critic.js (Voyager critic.txt)
- Spawns `pi -p` with a JSON-only critic prompt before a proposal is
written. {reasoning, success, critique}.
- success=true short-circuits the proposal (bot recovered between
detector tripping and now), saving Pi tokens on false positives.
- critique is spliced into the proposal body via attachCritique() so
the downstream auto-patcher has a sharp spec.
- Graceful: pi missing / timeout / unparseable JSON → proposal still
filed without the critic block.
2. scripts/lint-patch.js (Mindcraft coder._lintCode)
- Pre-flight gate between Pi commit and npm test: node --check, dynamic
import (catches missing named exports), regex extraction of
runSkill("id") calls cross-checked against the live registry.
- Cheaper than npm test, fails fast with a clear reason.
3. runtime/stuck-incident.renderActionTemplate (Voyager action_template.txt)
- All proposal bodies now follow the same fixed-section layout: Task /
Last result / Execution error / State / Metrics / Journal /
Scenarios / Critique / Fix / Edit scope / Forbidden.
4. runtime/skill-library.js (Mindcraft skill_library.getRelevantSkillDocs)
- Word-overlap ranking (Mindcraft's offline fallback) — zero deps,
deterministic. auto-patch.js injects top-3 similar skills into the
Pi prompt as "look at these patterns".
5. runtime/modes.js (Mindcraft modes.js)
- Declarative {name, interrupts, on, active, update(ctx)} chain that
runs BEFORE the curriculum each tick.
- Ships self_preservation (low HP → eat/flee), hunger (food<14 → eat),
night_shelter (night + bed in hand → sleep). Cleaner than ad-hoc
lastFleeAttempt cooldowns in reflex.js.
6. runtime/social/conversation.js + cmd:conv-say/conv-recent/conv-list
- File-JSONL topic channel so two bots from the same repo (different
usernames, different host dirs under state/) can append turns and
read peers. Skeleton — multi-agent collaboration on top later.
Differentiator preserved: every Pi-written skill still lands on main via
auto-patch.js (real git branch + smoke gate + cherry-pick). Voyager
keeps skills in a Chroma JSON, Mindcraft keeps them in RAM — pepa keeps
them as versioned source code reviewable in `git log`.
package.json: 0.0.1 → 0.1.0. 174/174 tests pass. README + AGENTS updated.
