ulw-plan — Explore-First Planning Consultant

Turns a vague or large request into one decision-complete work plan: it explores the codebase first, asks only the real forks, and writes the plan only after your explicit okay.

What it does

This skill puts the agent into a planner-only persona called Prometheus. It never edits product code and never delegates implementation.

  • The activating turn opens with the exact line ULW-PLAN MODE ENABLED!, followed by a no-implementation pledge and a preview of the workflow.
  • It grounds in your repository first using LSP tools, ast-grep, ripgrep and parallel read-only explore agents. Anything discoverable is researched, never asked.
  • It makes one intent verdict — CLEAR (you know the outcome) or UNCLEAR (the goal itself is fuzzy) — and announces it. CLEAR means it asks only genuine owner-decisions; UNCLEAR means it adopts and announces best-practice defaults instead of interviewing you.
  • Nothing durable is written until you explicitly approve; then a scaffold script generates .omo/plans/<slug>.md and task batches are appended.
  • Every executable item must be a column-zero checklist row (- [ ] 1. title) with references, acceptance criteria, agent-executed happy/failure QA, commit unit and an executor category.
  • Asking for "high accuracy" / "deep review" opens a gated adversarial review of the plan itself before handoff.

Who it's for

  • Developers tired of an AI charging into the wrong implementation and burning time on rework
  • Anyone handing multi-file refactors or features to a separate worker session
  • Teams that want plan and execution split, with a reviewable spec left behind
  • Power users already running the oh-my-openagent / omo-senpi harness

Examples

  1. Fuzzy brief — "make auth better" routes to UNCLEAR: the agent maps your current auth flow, picks defensible best-practice defaults, announces them, and presents a plan brief for approval.
  2. Concrete feature — "add a 5/min-per-IP rate limit to /login" routes to CLEAR: it asks only owner-decisions (Redis vs in-memory store, which middleware layer) and then writes step-by-step todos with QA evidence paths.
  3. High-accuracy pass — appending "high accuracy" flips review_required, so the finished plan goes through a reviewer round and gaps are repaired before handoff.
  4. Separate execution — once the plan exists, a fresh /start-work session executes it with zero further interview.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the packages/omo-senpi/skills/ulw-plan folder from the GitHub repo code-yeongyu/oh-my-openagent into my ~/.claude/skills/code-yeongyu-ulw-plan-2/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/code-yeongyu/oh-my-openagent.git /tmp/oh-my-openagent && mkdir -p ~/.claude/skills && cp -r /tmp/oh-my-openagent/packages/omo-senpi/skills/ulw-plan ~/.claude/skills/

This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and cd into a folder you use for tools.
  2. Clone the repository: git clone https://github.com/code-yeongyu/oh-my-openagent.git
  3. Create the skills folder if needed: mkdir -p ~/.claude/skills
  4. Copy the whole skill directory: cp -r oh-my-openagent/packages/omo-senpi/skills/ulw-plan ~/.claude/skills/ — the bundled references/ and scripts/ folders are required.
  5. Verify with ls ~/.claude/skills/ulw-plan that SKILL.md, references and scripts are all present.
  6. Make sure Node.js or Bun is installed so scripts/scaffold-plan.mjs can run (node -v).
  7. Restart Claude Code, then type ulw-plan or "make a plan before coding".
  8. You should see ULW-PLAN MODE ENABLED! as the first line. Answer any questions, review the approval brief, and reply "okay" — the plan is then written under .omo/plans/.
