daniel-powers

25 skills, guardrail hooks, and a parallel-agent worktree workflow for building software with Claude Code.

Install

In Claude Code, register the marketplace, then install the plugin:

/plugin marketplace add danielkosten/daniel-powers
/plugin install daniel-powers@daniel-powers

The first command registers the marketplace; the second enables the plugin. Skills appear as slash commands and the guardrail hooks activate immediately.

Requirements

The core Flow and Practice skills need only Claude Code. Some skills have external dependencies — install these only if you use the skill:

Skill	Needs
/python-automation	uv, ruff, mypy
/gemma-local	Apple Silicon + MLX (mlx_lm / mlx_vlm) + a local Gemma model
/graphify	pip install graphifyy — optional: MOONSHOT_API_KEY (Kimi backend), Neo4j (graph export)
/obsidian, /obsidian-cli	Obsidian app running + the obsidian CLI
/obsidian-markdown, /obsidian-bases, /json-canvas, /vault-tidy	an Obsidian vault at $OBSIDIAN_VAULT (default ~/Documents/Obsidian Vault)

What's inside

Skills are slash commands. Type /shape, /tdd, /graphify etc. in Claude Code.

Flow — the build pipeline (10 skills)

Skill	What it does
/shape	Frame a new idea before coding — explore, grill, route to issue or PRD
/architect	Turn an approved PRD into a vertical plan, dispatch to implementers
/to-prd	Publish a shaped change as a formal PRD on the issue tracker
/to-issues	Create ready-to-grab issues from a PRD or architect plan
/triage	Gate issues before they enter the build flow — confirm shaped, set priority
/project-setup	Scaffold the project contract — rigor tier, CLAUDE.md anchor, minimal docs
/session-cleanup	End-of-session close-out — changelog, stale docs, quality gate
/commit-pr	Commit, push, and open a PR in one disciplined pass
/handoff	Compact this conversation into a doc so a fresh agent can continue
/review	Two-axis pre-PR review: coding standards + spec faithfulness

Practice — craft skills (8 skills)

Skill	What it does
/tdd	Test-drive behavior changes through red-green-refactor
/clean-codebase	Module depth, naming-as-docs, minimal complexity — AI-friendly code
/prototype	Throwaway prototype to flesh out a design — terminal logic mock or UI variations
/sql	Database-querying practice — schema first, narrow queries, EXPLAIN, capture learnings
/self-review-before-reporting	Self-review checklist before any output the user will act on
/python-automation	Python automation practice — uv, ruff, mypy, resilient patterns
/gemma-local	Local model for OCR, image/audio/video analysis, JSON extraction
/skill-audit	Audit the plugin's skill set for debt — stale, bloated, overlapping

Obsidian — vault skills (7 skills)

Skill	What it does
/obsidian	Navigate, query, and maintain your vault — entry point to all Obsidian skills
/obsidian-cli	Terminal operations: search, read, create, properties, tasks
/obsidian-markdown	Write Obsidian Flavored Markdown — wikilinks, callouts, frontmatter
/obsidian-bases	Create and edit Obsidian Bases (.base files)
/json-canvas	Create and edit JSON Canvas files (.canvas)
/graphify	Turn your vault (or any folder) into a navigable knowledge graph
/vault-tidy	On-demand hygiene: fix broken links, place orphans, flag stale/duplicate notes

The Obsidian skills look for your vault at $OBSIDIAN_VAULT, falling back to the standard location ~/Documents/Obsidian Vault.

Hooks

Nine always-on guardrail hooks ship with the plugin:

Hook	When it fires	What it does
detect-new-project	Session start	Nudges you to scaffold docs when starting in a real project folder with none
worktree-presence	Session start	Warns on linked-worktree clutter and on two agents in the same worktree
keep-going	When Claude stops	Continues agreed work toward the confirmed goal without asking "shall I proceed?"
mentor-classifier	Every prompt	Re-anchors the classify-and-challenge habit for new initiatives
git-guardrails	Before any Bash	Blocks irreversible git ops — force-push, hard reset, whole-tree discard
worktree-tripwire	Before Bash / Edit / Write	Blocks git switch -c in the primary checkout; warns once per session on default-branch edits
uuid-check	Before git commit	Warns if staged code adds a hardcoded UUID literal
doc-staleness	Before editing a file	Warns when a doc's last-updated date is >90 days old
auto-format	After editing a file	Runs the project's formatter on the file just written

Parallel agents — the worktree workflow

If you run several Claude Code sessions on one repo at the same time, they share a single working tree, branch, and index — they overwrite each other. This plugin ships a worktree workflow that isolates each stream: one task = one git worktree = one branch.

wt new   <topic>           # ../<repo>-<topic> on a fresh branch off main
wt list                    # what's live, with marker-age signal
wt done  <topic>           # remove worktree + branch (only if merged or clean)
wt sweep [--apply]         # report (or remove) stale worktrees + merged branches

The worktree-tripwire and worktree-presence hooks ship enabled. The wt helper is at plugins/daniel-powers/bin/wt in your plugins dir — symlink it onto your PATH once:

ln -sfn "$HOME/.claude/plugins/marketplaces/daniel-powers/plugins/daniel-powers/bin/wt" "$HOME/.local/bin/wt"

Background: docs/parallel-agents.md. Decision: docs/adr/0017.

Flow — how the skills connect

shape → (issue lane) → to-issues → implement
shape → (PRD lane)   → to-prd → architect → to-issues → implementers (in parallel)
any branch → review → commit-pr

tdd and clean-codebase run inside any implementation. python-automation for Python work. session-cleanup and handoff at the end of any session. skill-audit periodically. Obsidian skills for vault work — start with /obsidian.
