ce:ideate

A workflow that generates and ranks improvement ideas grounded in the current project.

In plain words
What is it for?
Use it to explore improvements, evaluate possible directions, and create a ranked ideation document in docs/ideation/.
Why use it?
It helps you choose worthwhile directions before turning one idea into a detailed design or implementation plan.

Made for: Claude Code, Codex.

Per session 101 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ce:ideate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Generate Improvement Ideas

Note: The current year is 2026. Use this when dating ideation documents and checking recent ideation artifacts.

ce:ideate precedes ce:brainstorm.

  • ce:ideate answers: "What are the strongest ideas worth exploring?"
  • ce:brainstorm answers: "What exactly should one chosen idea mean?"
  • ce:plan answers: "How should it be built?"

This workflow produces a ranked ideation artifact in docs/ideation/. It does not produce requirements, plans, or code.

Interaction Method

Use the platform's blocking question tool when available (question in OpenCode, request_user_input in Codex, ask_user in Gemini; in Pi, use the blocking-question extension if available, otherwise present numbered options in chat and wait). Otherwise, present numbered options in chat and wait for the user's reply before proceeding.

Ask one question at a time. Prefer concise single-select choices when natural options exist.

Focus Hint

<focus_hint> #$ARGUMENTS </focus_hint>

Interpret any provided argument as optional context. It may be:

  • a concept such as DX improvements
  • a path such as plugins/systematic/skills/
  • a constraint such as low-complexity quick wins
  • a volume hint such as top 3, 100 ideas, or raise the bar

If no argument is provided, proceed with open-ended ideation.

Core Principles

  1. Ground before ideating - Scan the actual codebase first. Do not generate abstract product advice detached from the repository.
  2. Generate many -> critique all -> explain survivors only - The quality mechanism is explicit rejection with reasons, not optimistic ranking. Do not let extra process obscure this pattern.
  3. Route action into brainstorming - Ideation identifies promising directions; ce:brainstorm defines the selected one precisely enough for planning. Do not skip to planning from ideation output.

Execution Flow

Phase 0: Resume and Scope

0.1 Check for Recent Ideation Work

Look in docs/ideation/ for ideation documents created within the last 30 days.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ce:ideate is a skill published in the GitHub repository marcusrbrown/systematic (24 stars, last pushed 3d ago), licensed MIT. It adds 101 tokens to every session and 2,209 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
