Ecosystem Update — 2026-04-16 (rerun)

April 16, 2026 · generated by the ecosystem-update Claude Skill

TL;DR

Same-day rerun; tier 2/3 not re-fetched (tier 2 <24h, tier 3 <7d). Delta vs. morning run is small.
No new safe Quick Wins: every viable candidate requires either new files or editing constitutional CLAUDE.md, both blocked by skill hard limits.
Three Build Queue additions from Boris's catalog (/simplify, /babysit) and shanraisshan's rules-modularization pattern.

Quick Wins

None this run. The morning run's CLAUDE_CODE_AUTO_COMPACT_WINDOW=400000 is already applied (settings.json:59). All other fresh candidates either require creating new files (out of scope for Quick Wins per skill hard limits) or touching ~/.claude/CLAUDE.md (hard-blocked).

Build Queue

/simplify command (slash-command) — howborisusesclaudecode.com — spawns parallel subagents reviewing a codebase slice for reuse, quality, efficiency. Distinct from /techdebt (dup detection) by its quality/reuse lens. Implement as ~/.claude/commands/simplify.md with allowed-tools: Agent, Read, Grep; body dispatches 3–5 Explore subagents each scoped to a concern (reuse, naming, dead code).
/babysit command (slash-command) — howborisusesclaudecode.com — loops on CI/PR-review output, auto-applies safe fixes, retries. Useful for long CI tail when merging. Implement as ~/.claude/commands/babysit.md with allowed-tools: Bash(gh *), Edit, Agent; body polls gh pr checks, ingests failure text, dispatches worker agent with a contract.
.claude/rules/ modularization (CLAUDE.md pattern) — shanraisshan/claude-code-best-practice — break long policy doc into ~/.claude/rules/*.md and reference via @import-style pointers. Blocked by hard limit on CLAUDE.md edits during this skill run; tracked for manual decision.

Research

No new arxiv fetch this run (tier 2 last run 2026-04-16T00:00Z, within 24h). Carry forward from morning: - arXiv:2604.11790 ClawGuard - arXiv:2604.11950 AnyPoC - arXiv:2604.12301 Local-Splitter - arXiv:2604.15034 Autogenesis - arXiv:2604.12948 Dual-trace memory — already shipped end-to-end in omni-mem as migration v8.

Already Have

Auto Mode, Ultraplan, Routines, /schedule, /loop, Channels webhooks, voicemode-mcp, Agent Teams (govern), PreCompact hook, UserPromptSubmit hook, Stop hook, SessionStart hook (omni-mem briefing), SessionEnd hook (notify), SubagentStop hook, PostToolUse edit verify, PreToolUse bash guard, context-fork pattern, isolation-worktree agents, ccstatusline, companion, skill-creator, claude-rules-doctor, tdd-guard-hook, instinct-scoring, context-engineering-kit, session-teleportation, trailofbits security plugins (4 enabled), CLAUDE_CODE_AUTO_COMPACT_WINDOW=400000, includeCoAuthoredBy=false, opus-4-7 for planner/reviewer tier, dual-trace scene_context schema in omni-mem.

Rejected

--bare launch flag — CLI flag, not a settings.json knob; already available for scripts that need fast SDK startup (e.g., hooks). No config change possible.
"CLAUDE.md ≤ 200 lines" guideline — current file is 241 lines; governance/policy density is justified by auto-runtime contract, route taxonomy, and anti-stop-pattern lessons. Shrinking would lose load-bearing rules. Rejected as a size-only heuristic that doesn't apply here.
Clawd on Desk (carried from morning) — overlaps with companion skill.
claude-pace statusline (carried from morning) — duplicate of ccstatusline.
Computer Use MCP (macOS screen control) (carried from morning) — attack-surface fail.

Auto-Implemented

None — dry-run mode.
