Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00184 | $0.05343 |
| Opus 5 | $0.00092 | $0.02671 |
| Sonnet 5 | $0.00037 | $0.01069 |
| Haiku 4.5 | $0.00018 | $0.00534 |
Grade A, and why
ce-design 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 8d 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 — 384 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CE Design — the route that has a design leg
What this route fixes
The Compound Engineering loop (brainstorm → plan → work) spends most of its effort on what problem are we solving, and never answers what should this look like, given that problem. The result is that you find out the thing is ugly after the MVP exists — the single most expensive moment to discover it. This route moves the design decision to before any code is written, and then holds the build to it.
Two entry points — you choose whether design happens
| You type | You get |
|---|---|
/ce-design <pain point> |
brainstorm → design → plan (this skill orchestrates the whole thing) |
/ce-brainstorm <pain point> |
brainstorm → plan (no design — upstream Compound Engineering, untouched) |
Whether to design is decided by which entry point you pick — this skill never stops mid-flow to ask "should we design this?".
Why this is a wrapper, not a fork
This skill modifies no file inside the compound-engineering plugin. It calls that
plugin's ce-brainstorm / ce-plan skills through the Skill tool. Reason: editing an
installed plugin's files means the next plugin update silently overwrites your work and the
feature vanishes. A wrapper keeps working.
The residual soft dependency, stated plainly: this skill depends on the names
ce-brainstorm and ce-plan existing. If upstream renames or restructures them, this skill
degrades gracefully (worst case: ce-brainstorm's own handoff menu appears and you pick
"create implementation plan", which skips design) — it does not hard-fail.
Rule when editing this file: depend only on skill names. Never depend on their phase numbers, menu wording, or internal section headings — those change between versions.
Where it sits in the CE loop (order matters — do not invert it)

What ships with it
7 files 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.
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-design is a skill published in the GitHub repository waveriderai/ce-design-flow (1 stars, last pushed 1mo ago), licensed MIT. It adds 184 tokens to every session and 5,343 once invoked, about $0.0009 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 2026-08-31.

system-pitch
Write a design system investment pitch with a business case and ROI framing. Trigger when someone says: pitch the design system, make the case for the system, sell this to leadership, justify the investment, business case for design systems, why should we invest in a design system, or anything about building an…
ai-component-description
Generate AI-optimised text descriptions for components, formatted for Figma's MCP server and LLM consumption. This produces prose descriptions in a six-section format (purpose, props, anti-patterns, composition, accessibility, examples), NOT JSON schemas or structured data files. Trigger when someone says: write…
context-engine-builder
Generate a context engine — seven structured blueprint files (UX, UI, content, accessibility, ethical, technical, business intelligence) that encode everything an AI agent needs to work with a design system. This produces YAML infrastructure in .ai/context-engine/, NOT a health score or quality assessment. Trigger…
stakeholder-brief
Write a one-page stakeholder brief translating design system health or status into business language. Trigger when someone says: stakeholder update, exec brief, leadership summary, status report for leadership, system status for non-designers, write a brief for the business, or anything about communicating design…
token-audit
Audit a design system's token definitions for naming violations, missing semantic tiers, and structural debt. This audits how tokens are defined and organised, NOT how they are consumed in code. Trigger when someone says: audit my tokens, token naming review, are my tokens consistent, token health check, review my…
token-compliance
Check a codebase or implementation for token compliance — finding hardcoded values, wrong-tier token references, and inconsistent token application in consuming code. This checks how tokens are used in code, NOT how the tokens themselves are defined or structured. Trigger when someone says: are we using tokens…
