Waza

Tw93's engineering habits, turned into your skills.

English · 中文 · 繁體 · 日本語 · 한국어 · Deutsch · Français

Each engineering habit gets an installed skill, a folder with reference docs, helper scripts, and gotchas from real failures. In Claude Code, type the slash command. In Codex, invoke the installed skill by name and follow the same playbook.

Claude Code, Codex, Cursor, and other agents

npx skills add tw93/Waza -a claude-code codex cursor -g -y

One copy lands in ~/.agents/skills, the shared skills directory. Claude Code is symlinked in; Codex, Cursor, Gemini CLI, Copilot, Amp, Kimi Code CLI, and every other agent that reads that directory picks the eight skills up as /check, /think, and so on. Agents with a private skills directory take their id after -a (for example antigravity-cli or qwen-code). Update with npx skills update -g -y. You can also tell your agent to install it:

Install Waza for me by reading https://github.com/tw93/Waza/blob/main/llms.txt

Host plugin, if you prefer the host's own update command (skills are namespaced, /waza:check)

# Claude Code (update: claude plugin update waza)
/plugin marketplace add tw93/Waza
/plugin install waza@waza

# Codex (update: codex plugin marketplace upgrade waza, then codex plugin add waza@waza)
codex plugin marketplace add tw93/Waza
codex plugin add waza@waza

Claude Desktop: download waza.zip, open Customize > Skills > "+" > Create skill, and upload the ZIP. To update, click "..." on the skill card, choose Replace, and upload the latest ZIP.

Pi: pi install npm:@tw93/waza, update with pi update npm:@tw93/waza.

You decide how skills chain together. Each skill stops at the requested outcome; an explicitly authorized workflow continues without asking you to approve every transition.

Common workflows:

• Plan a feature: /think to settle the plan, implement after approval, then /check before merging
• Ship a fix: /hunt to find the root cause, fix it, then /check to review the changes and, when needed, handle release, publish, push, and issue follow-through
• Research and write: /read to fetch sources, /learn to synthesize, /write to polish

Waza ships only generic engineering habits. /check becomes project-aware at runtime by reading the target repository's public context (READMEs, package manifests, Makefiles, CI workflows) and your task constraints, never private paths, credentials, or tokens. See skills/check/references/project-context.md for the review context template.

Curl URLs use the latest GitHub release asset. Set WAZA_REF=main before the command if you want bleeding-edge scripts.

A minimal statusline for Claude Code: context window, 5-hour quota, and 7-day quota. Color-coded by usage, no progress bars, no noise.

(
  set -e
  WAZA_STATUSLINE_SCRIPT="$(mktemp -t waza-statusline.XXXXXX)"
  trap 'rm -f "$WAZA_STATUSLINE_SCRIPT"' EXIT
  curl -fL https://github.com/tw93/Waza/releases/latest/download/setup-statusline.sh -o "$WAZA_STATUSLINE_SCRIPT"
  # review it first: less "$WAZA_STATUSLINE_SCRIPT"
  bash "$WAZA_STATUSLINE_SCRIPT"
)

Codex has native statusline items. Add to ~/.codex/config.toml:

[tui]
status_line = ["model-with-reasoning", "current-dir", "context-used", "five-hour-limit", "weekly-limit"]
status_line_use_colors = true

Codex shows remaining quota; the Claude Code statusline above shows used percentage (upstream does not yet expose five-hour-used / weekly-used).

Optional rules apply beyond skill invocations when installed into your agent's persistent instructions. Installing Waza skills alone does not enable them. Copy the ones you want (swap claude-code for codex or antigravity-cli on those agents):

(
  set -e
  WAZA_RULE_SCRIPT="$(mktemp -t waza-rule.XXXXXX)"
  trap 'rm -f "$WAZA_RULE_SCRIPT"' EXIT
  curl -fL https://github.com/tw93/Waza/releases/latest/download/setup-rule.sh -o "$WAZA_RULE_SCRIPT"
  # review it first: less "$WAZA_RULE_SCRIPT"

  # English coaching: appends a short 😇 correction when your prompt has an English mistake
  bash "$WAZA_RULE_SCRIPT" english claude-code

  # Anti-patterns: always-on cross-skill guardrails (read before acting, no scope creep, no unsolicited summaries)
  bash "$WAZA_RULE_SCRIPT" anti-patterns claude-code

  # Routing hint: tells non-Claude hosts to prefer Waza skills when a request matches their triggers
  bash "$WAZA_RULE_SCRIPT" waza-routing claude-code

  # Clear everyday replies: consistent terms, explicit conditions, preserved uncertainty
  bash "$WAZA_RULE_SCRIPT" clarity claude-code
)

Clarity uses clear-writing principles from ASD-STE100 without imposing controlled-English grammar or changing your voice. Re-run its command to update the installed rule, then start a new session. Codex installs a marked block in ~/.codex/AGENTS.md; Claude Code and Antigravity install a rule file. For other tools, copy the rule into their persistent custom instructions.

Waza (技, わざ) is a Japanese martial arts term for technique: a move practiced until it becomes instinct. A good engineer does more than write code. They pressure-test requirements, debug to root cause, review their own diffs, and read primary sources. AI has the raw output for all of it, but without structure that output drifts into generic, imprecise work. Each Waza skill states the outcome, the red lines, and how the result gets verified, then steps back and lets the model choose the path. As models improve, that restraint pays compound interest.

Tools like Superpowers and gstack are powerful but heavy: too many skills, too much configuration. Waza stays small, eight skills for the habits that actually matter, each with one job and a clear trigger. The skills were built from real projects and refined through 300+ sessions across 7 projects, and every gotcha traces to a real failure. The /health skill grew from the six-layer Claude Code framework in this post.

Part of a trilogy: Kaku (書く) writes code, Waza (技) drills habits, Kami (紙) ships documents. Think of them as a family: Kaku is the dad, Waza the big sister, Kami the little sister.

npx skills remove tw93/Waza -g
rm -f ~/.claude/statusline.sh
rm -f ~/.claude/rules/english.md
rm -f ~/.claude/rules/anti-patterns.md
rm -f ~/.claude/rules/waza-routing.md
rm -f ~/.claude/rules/clarity.md

For the statusline, also remove the statusLine entry from ~/.claude/settings.json. For Claude Desktop, delete Waza from Customize > Skills. For Codex rule installs, remove the marked Waza blocks from ~/.codex/AGENTS.md. For Antigravity, remove the selected rule file from ~/.gemini/antigravity-cli/rules/. Remove copied rules from other tools' custom instructions. Start a new session after removing a rule.

• The most direct way to support me is getting Mole for Mac, my paid Mac cleanup app
• If Waza helped you, give it a star, share it, or open an issue or PR
• I have two cats, TangYuan and Coke, and if Waza has been helpful to you, you can feed them canned food 🥩
