killall-skills

Domain-focused workflow skills for coding agents.

What ships

• skills/planning/ — project planning, PRDs, issue slicing, triage, and wayfinding.
• skills/engineering/ — implementation, diagnosis, review, Git maintenance, and delivery.
• skills/architecture/ — domain modeling and deep-module design.
• skills/knowledge/ — research, handoffs, and cross-project wikis.
• skills/experimental/ — prototypes and extension authoring.
• agents/ — Claude Code subagents used by some skills.
• hooks/voice-readback/ — optional turn-completion hook, registered only on request.

Install

Everything installs through the cross-agent skills CLI, which reads the skills/<domain>/<name>/ catalog directly.

npx skills@latest add killallgit/killall-skills --list

Install what you want, for the agents you use:

npx skills@latest add killallgit/killall-skills \
  --skill research \
  --skill diagnose \
  --agent claude-code \
  --agent codex \
  --global \
  --yes

Take a whole domain by naming its skills, or take everything with --skill '*':

npx skills@latest add killallgit/killall-skills --skill '*' --agent claude-code -g -y

Skills land in each agent's own directory — ~/.claude/skills/ for Claude Code, ~/.codex/skills/ for Codex — so they work without any marketplace or plugin host. Drop --global to install into the current project instead.

Update or remove them the same way:

npx skills@latest update
npx skills@latest remove research

Agents

The skills CLI installs skills, not subagents. Three skills call subagents that live in agents/: git-janitor uses git-janitor-investigator, project-planner has a matching agent, and commenator audits comments on demand. Copy the ones you want into your agent directory:

cp agents/*.md ~/.claude/agents/

Each skill still works without its agent — it just runs the investigation inline.

Local development

Point the CLI at a checkout instead of the GitHub repo:

npx skills@latest add ~/Code/killallgit/killall-skills --list

Run the tests with:

uv run --with pytest pytest tests -q
