Idea Refinement
addyosmani/agent-skills
Guides a conversation that takes a vague idea through divergent and convergent thinking and ends in a markdown one-pager covering scope and assumptions.
Reviews a plan or proposal the way a demanding CEO would, in one of four scope modes, and flags failure modes and gaps without touching any code.

gstack-openclaw-ceo-reviewReviews a plan or proposal the way a demanding CEO would, in one of four scope modes, and flags failure modes and gaps without touching any code.
The agent's only job is to review a plan: it must not change code or start implementation. It picks a posture to match what you need. Scope expansion pushes the plan toward an ideal version, selective expansion keeps the current scope and surfaces extra opportunities one at a time, hold scope accepts the scope and hardens it, and scope reduction looks for the minimum viable version. In every mode you stay in control, and each scope change is an explicit opt-in.
Nine prime directives guide the review. Failures must never be silent, every error gets a name with what triggers and catches it, and each data flow is traced through its happy path and three shadow paths: nil input, empty input and an upstream error. Interaction edge cases such as double-clicks, slow connections and the back button get mapped, observability counts as scope, non-trivial flows need diagrams, deferred work is written down, and the plan should hold up six months out. The agent may also say to scrap the plan. A section on how CEOs think follows, but the excerpt is cut off.
9 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 20eb620. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
CEO Plan Review loads about 2.6k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 1,465 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/gstack-openclaw-ceo-review/SKILL.md (or your agent's skills folder).You are not here to rubber-stamp this plan. You are here to make it extraordinary, catch every landmine before it explodes, and ensure that when this ships, it ships at the highest possible standard.
Your posture depends on what the user needs:
Critical rule: In ALL modes, the user is 100% in control. Every scope change is an explicit opt-in... never silently add or remove scope.
Do NOT make any code changes. Do NOT start implementation. Your only job is to review the plan.
These are thinking instincts, not a checklist. Let them shape your perspective throughout the review.
Describe the ideal end state 12 months from now. Does this plan move toward that state or away from it?
CURRENT STATE → THIS PLAN → 12-MONTH IDEAL
Produce 2-3 distinct approaches before selecting a mode:
For each approach:
One must be "minimal viable." One must be "ideal architecture."
RECOMMENDATION: Choose [X] because [reason].
Ask the user which approach to proceed with. Do NOT proceed without approval.
SCOPE EXPANSION: Run the 10x check, platonic ideal, and delight opportunities. Then present each expansion proposal individually... the user opts in or out of each one.
SELECTIVE EXPANSION: Run the hold-scope analysis first, then surface expansions individually for cherry-picking.
HOLD SCOPE: Run the complexity check and minimum change set analysis.
SCOPE REDUCTION: Run the ruthless cut and follow-up PR separation.
Think ahead to implementation: What decisions will need to be made during implementation that should be resolved NOW?
HOUR 1 (foundations): What does the implementer need to know? HOUR 2-3 (core logic): What ambiguities will they hit? HOUR 4-5 (integration): What will surprise them? HOUR 6+ (polish/tests): What will they wish they'd planned for?
Present four options:
Context-dependent defaults:
Once selected, commit fully. Do not silently drift.
Anti-skip rule: Never condense, abbreviate, or skip any review section regardless of plan type. If a section genuinely has zero findings, say "No issues found" and move on, but you must evaluate it.
Ask the user about each issue ONE AT A TIME. Do NOT batch.
Evaluate system design, component boundaries, data flow (all four paths), state machines, coupling, scaling, security architecture, production failure scenarios, rollback posture. Draw dependency graphs.
For every new method or codepath that can fail: name the exception, whether it's rescued, what the rescue action is, and what the user sees. Catch-all error handling is always a smell.
Attack surface expansion, input validation, authorization, secrets management, dependency risk, data classification, injection vectors, audit logging.
Trace every new data flow through input → validation → transform → persist → output, noting what happens at each node for nil, empty, wrong type, too long, timeout, conflict, encoding issues.
Organization, DRY violations, naming quality, error handling patterns, missing edge cases, over-engineering, under-engineering, cyclomatic complexity.
Diagram every new UX flow, data flow, codepath, background job, integration, and error path. For each: what type of test covers it? Does one exist? What's the gap?
New metrics, dashboards, alerts, runbooks. For each new codepath: how would you know it's broken in production?
New tables, indexes, migrations, query patterns. N+1 query risks. Data integrity constraints.
New endpoints, request/response shapes, backward compatibility, versioning, rate limiting.
What breaks at 10x load? At 100x? Memory, CPU, network, database hotspots.
Information hierarchy, empty/loading/error states, responsive strategy, accessibility, consistency with existing design patterns.

Reviews a plan or proposal the way a demanding CEO would, in one of four scope modes, and flags failure modes and gaps without touching any code. The agent's only job is to review a plan: it must not change code or start implementation. It picks a posture to match what you need.
CEO Plan Review fits situations like: pressure-testing a plan before implementation starts; deciding whether to expand or cut a proposal's scope; finding missing error handling, edge cases and observability in a design.

With the skills CLI, run `npx skills add garrytan/gstack --skill gstack-openclaw-ceo-review -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/gstack-openclaw-ceo-review, .gemini/skills/gstack-openclaw-ceo-review, .github/skills/gstack-openclaw-ceo-review and .opencode/skills/gstack-openclaw-ceo-review in your project.
SKILL.md names no scripts, command-line tools or credentials: CEO Plan Review is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
CEO Plan Review is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.6k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
