Ecosystem Update — 2026-04-02

April 2, 2026 · curated by Chad Simon · 16 items reviewed

Highlights

All isolation-eligible agents now have isolation: worktree — isolation coverage complete
type: prompt hooks confirmed by community — allows inline LLM-as-validator hooks with no Python script required; verify syntax before wiring
Build Queue additions: Dippy (AST bash auto-approve), claude-rules-doctor (dead-rule detector), claude-tmux

Dippy hook

github.com/ldayton/Dippy

AST-based bash auto-approve that semantically classifies safe vs destructive commands; complements pre_tool_guard.py's regex approach with actual syntax-tree analysis
claude-rules-doctor tool

github.com/nulone/claude-rules-doctor

Detects dead .claude/rules/ globs by validating patterns match files; wire to SessionStart or run periodically as CLAUDE.md grows
claude-tmux mcp/client

github.com/hesreallyhim/awesome-claude-code

Manage Claude Code sessions within tmux; pairs with existing worktree + parallel-agent patterns
PermissionDenied hook hook

coleam00/claude-code-new-features-early-2026

New hook event (not in current settings.json); fires when permission is denied; verify event name stability before wiring script
TDD Guard hook

github.com/nizos/tdd-guard

PostToolUse hook blocking non-TDD file changes _(carried from previous run)_
cc-devops-skills skill

github.com/akin-ozer/cc-devops-skills

IaC-focused DevOps skills with validators, generators, CLI tools _(carried from previous run)_

type: prompt hook type — gist community — Hooks can use "type": "prompt" to run inline LLM-as-validator without a Python script; Impact=2, Effort=1 — verify exact settings.json syntax against official docs before implementing. If confirmed, can replace some lightweight Python guard scripts.

github.com/alexfizio/653c5164d726987569ee8229a19f451f
type: prompt hooks on Stop / PostToolUse — Could add natural-language verification at Stop ("did this complete all acceptance criteria?") with zero new scripts; pending syntax verification
Session Teleportation / --teleport — built-in CLI flag _(carried)_
Dynamic !command injection in SKILL.md — embed shell output at skill load time _(carried)_

Items reviewed and explicitly declined this cycle, with the reason. Curation discipline matters more than coverage.

parry — removed 2026-04-02: false-positive taint blocked all tools session-wide; more harmful than protective at current sensitivity level
container-use (dagger) — alignment failure: git worktrees already provide agent isolation; Docker-based isolation requires a new service dependency without proof worktrees are insufficient
TypeScript Quality Hooks — covered by typescript-reviewer agent
cchooks Python SDK / claude-hooks TypeScript SDK — existing Python scripts work without an SDK layer
Claudio sounds hook — minor convenience only
Britfix — irrelevant to
