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.

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 | $0.00022 | $0.00502 |
| Opus 5 | $0.00011 | $0.00251 |
| Sonnet 5 | $0.00004 | $0.00100 |
| Haiku 4.5 | $0.00002 | $0.00050 |
Grade A, and why
ciel-frontend-and-hooks 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 7d 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.
What it actually says
CIEL ADAPTATION: Frontend & Hooks (The Component Layer)
This skill manages modern React development and the enforcement of local workspace rules.
React Development Patterns
- Composition First: Compose small components over complex inheritance.
- State Hygiene: Use
useMemofor sorting/filtering. UseuseCallbackfor props passed to children. - Fetching: Prefer
useQuerypatterns (SWR/React Query) for SSR-safe data retrieval. - Forms: Use controlled inputs with Zod schema validation. Fail fast on bad input.
Local Rules (Hookify)
- Events: Define rules for
bash(commands),file(edits),stop(completion), orprompt(workflow). - Actions:
warn: Show message; allow operation.block: Prevent operation (e.g., Adding API keys to.env).
- Organization: Rules live in
.claude/hookify.{name}.local.md. ALWAYS gitignore local rule files.
Visual Accessibility
- Keyboard: EVERY interactive element must be reachable via Tab and activatable via Enter/Space.
- Focus: Manage focus explicitly in Modals (Restore on Close).
Anti-Patterns
- Fat Components: Putting 500 lines of business logic in a single UI component.
- Prop Drilling: Passing state through 5+ layers instead of using Context or Zustand.
- RegEx Loopholes: Writing too-broad Hookify patterns (e.g.,
log) that cause noise.
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.

ciel-frontend-and-hooks is a skill published in the GitHub repository jxoesneon/Ciel (1 stars, last pushed 3d ago), licensed Apache-2.0. It adds 22 tokens to every session and 502 once invoked, about $0.0001 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 2026-09-03.
