Ecosystem Update — 2026-04-17 (DRY-RUN)

April 17, 2026 · generated by the ecosystem-update Claude Skill

TL;DR

Low-signal day: most fetched items appeared in prior seen_items (158 entries) and are already implemented or previously rejected.
Two genuinely new CLI-surface items (no-flicker-mode, --bare flag, <important if="..."> conditional tag, --add-dir multi-repo, /color, /go composite) — but all either require a new script/skill file (Build Queue, not Quick Win) or touch CLAUDE.md (hard-limit forbidden).
Net: 0 Quick Wins implementable under hard limits today. No config changes would be made on a non-dry run either.

Quick Wins

None. Every candidate that scored Priority ≥ 2.0 either required creating a new file (disallowed — Build Queue) or editing CLAUDE.md (hard-limit forbidden).

Build Queue

/go composite skill (skill) — Boris's howborisusesclaudecode.com — chains verify + simplify + PR creation into one invocation. Would be a new skill file under ~/.claude/skills/go/. Priority 2.0 but fails Quick Win (new file).
<important if="context"> conditional CLAUDE.md tag (claude-md) — shanraisshan/claude-code-best-practice — scopes rules so they fire only when a predicate matches (e.g. file type, stage). Would require editing constitutional ~/.claude/CLAUDE.md. Deferred to a manual review since policy doc is not auto-editable.
Rubric-guided reviewer agent (agent-pattern) — arXiv:2604.14261 (ReviewGrounder) — multi-agent review split into draft + ground-evidence stages with explicit rubric scoring. Could enhance ~/.claude/agents/reviewer.md with a rubric block; defer to a proper design pass rather than a blind frontmatter edit.

Research

ReviewGrounder: Rubric-Guided Tool-Integrated Agents (arXiv:2604.14261) — Two-stage reviewer pattern (draft → ground with evidence) directly applicable to the current reviewer agent and the R3/R4 expert-review requirement in CLAUDE.md.
Autonomous Evolution of EDA Tools (arXiv:2604.15082) — Hardware-specific self-evolving agent loop, but the "correctness + QoR-driven evaluation loop" structure parallels /evolve and is worth reading as prior art before the next /evolve iteration.
COEVO: Co-Evolutionary RTL Generation (arXiv:2604.15001) — Co-evolutionary correctness + performance-property optimization. Relevant pattern for any future dual-objective agent (safety + quality).

Already Have

All 158 entries in seen_items (see ~/.claude/state/ecosystem-update-last-run.json). Highlights confirmed present this scan: claude-pace-statusline, clawd-on-desk, ccxray, encyclopedia-agentic-coding-patterns, claude-code-hooks-mastery, autogenesis-paper, batch-command, btw-side-queries, auto-mode, postcompact-hook, permissionrequest-hook, simplify-command, xhigh-opus-47-default-effort, claude-code-auto-compact-window-env, claude-rules-subdirectory-modularization, type-prompt-hook-type, once-true-hooks, isolation-worktree-worker, context-fork-pattern, auto-dream-memory, teleport-flag, remote-flag, imessage-plugin.

Rejected

no-flicker-mode — CLI rendering feature auto-enabled by the Claude Code binary. Not user-configurable. Nothing to write.
focus-mode / /focus — Interactive CLI toggle. No settings.json surface.
power-ups — Interactive lesson system. Not a config change.
--bare flag — SDK-side startup flag. Interactive Claude Code sessions don't use it.
--add-dir flag — Invocation flag, set per-session. Not a persistent config item.
/color command — Cosmetic per-session. Already customizable via keybindings skill.
--name / auto-session-naming — Session-scoped convenience. No durable config footprint.
Hardware/quantum/HEP papers (arXiv:2604.14709, 2604.14696, 2604.15082 partial, 2604.14550, 2604.14609) — Domain-specific; patterns are interesting but not directly applicable to general multi-agent coding setup.
<important if="..."> conditional tag — Rejected as a Quick Win (touches CLAUDE.md). Kept in Build Queue as a manual review item.
