Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00071 | $0.00680 |
| Opus 5 | $0.00036 | $0.00340 |
| Sonnet 5 | $0.00014 | $0.00136 |
| Haiku 4.5 | $0.00007 | $0.00068 |
Grade A, and why
preview-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 10d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Topic: $ARGUMENTS
Preview the Design Convention
Renders a real Egregore artifact through this branch's MERIDIAN render path
(packages/egregore-artifacts local code) — deliberately not npx egregore-artifacts,
which pulls the published npm 0.10.2 (the OLD design). This is the test vector for
Design Convention Round 1: testers see the new design on real output before it merges.
Full protocol: memory/feedback/design-convention-r1/GUIDE.md.
When to invoke
User says: "/preview-design", "preview the design convention", "render with the new design", "let me test the new design on a document / handoff / board", or is running the design-convention round-1 test.
What it does
Run the bundled script — it handles dependency install and routes to the local CLI:
bash skills/preview-design/render.sh <surface> [file]
| Surface | Command | Input |
|---|---|---|
document |
render.sh document [file.md] |
any markdown — defaults to a bundled sample |
handoff |
render.sh handoff [file.json] |
a handoff-v1 JSON — defaults to a bundled sample |
platform |
render.sh platform |
reads memory/board/board.json (the board view) |
emissary |
render.sh emissary |
harness-only this round — prints the harness URL and stops |
The CLI opens the rendered HTML in the browser. After looking it over, the tester runs the
Socratic feedback protocol ("Run the Design Convention feedback protocol").
Why it's built this way
- Local, never
npx. It runsnode packages/egregore-artifacts/bin/cli.js, so you always get THIS branch's MERIDIAN design — npm'segregore-artifactsis the old look. - Lives in top-level
skills/, not.claude/skills/./updatereplaces.claude/skills/wholesale from upstream (git checkout upstream -- .claude/skills/), which would delete an org-local preview command. Top-levelskills/survives. - Emissary is excluded on purpose. Its renderer (
api/main.py) is server-side and not yet design-system-wired — wiring it is the #1 Round-2 task. For now it's reviewed via the published harness.
What ships with it
3 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.

preview-design is a skill published in the GitHub repository egregore-labs/egregore (289 stars, last pushed 6d ago), licensed MIT. It adds 71 tokens to every session and 680 once invoked, about $0.0004 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.
