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 | $0.00015 | $0.00581 |
| Opus 5 | $0.00008 | $0.00291 |
| Sonnet 5 | $0.00003 | $0.00116 |
| Haiku 4.5 | $0.00002 | $0.00058 |
Grade A, and why
security-review 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 9d 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: Security Review (Quality Gate)
This skill formalizes the "Security Gate" for CIEL. It provides non-negotiable patterns for secrets management, input validation, and vulnerability prevention.
The Security Mandates
1. Secrets Management
- Fail: Hardcoded keys in source or session notes.
- Pass: Use
process.envor secrets managers. Validate presence at startup. - Audit: Use
grep_searchfor common secret patterns (e.g.,sk-,password=) before any commit.
2. Input Validation (The Zod Pattern)
- All user-controlled input MUST be validated using a schema-first approach (e.g., Zod, Pydantic).
- Whitelist Only: Validate against a list of allowed characters/types, never a blacklist.
- File Sinks: Validate size, MIME type, and extension before writing to disk.
3. SQL Injection (Parameterized Queries)
- String concatenation in SQL is a CRITICAL violation.
- All database interactions MUST use parameterized queries or type-safe ORMs.
4. XSS & CSRF
- HTML: Sanitize all user-provided HTML using
isomorphic-dompurifyor equivalent. - Cookies: Use
HttpOnly,Secure, andSameSite=Strictfor all session tokens. - CSRF: Enforce CSRF token validation for all state-changing
POST/PUT/DELETEoperations.
5. Blockchain Safety (Solana/EVM)
- Signature Check: Verify wallet signatures before executing on-chain actions.
- Balance Gate: Perform pre-transaction balance checks to prevent revert-spamming.
Anti-Patterns
- Logging the World: Printing full objects that might contain
password,token, orcvv. - Stack-Trace Leaks: Returning raw error objects to the client.
- Blind Merging: Merging dependencies without running
npm audit.
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.

security-review is a skill published in the GitHub repository jxoesneon/Ciel (1 stars, last pushed 5d ago), licensed Apache-2.0. It adds 15 tokens to every session and 581 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.
