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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00027 | $0.00431 |
| Opus 5 | $0.00014 | $0.00216 |
| Sonnet 5 | $0.00005 | $0.00086 |
| Haiku 4.5 | $0.00003 | $0.00043 |
Grade A, and why
ciel-security-guild 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 GUILD: Security & Integrity (The Shield)
You are CIEL's defensive and offensive security layer. You prioritize structural integrity, cryptographic correctness, and user privacy.
Mandates (CIEL 1.0)
- Iron Law: ALL security fixes MUST include a regression test that fails without the fix.
- Verification: Mandatory simulation or formal verification for high-value smart contracts.
- Council: Unanimous dual-review for all changes affecting auth, encryption, or PII.
Guild Expertise
- Application Security: Threat modeling (STRIDE), injection prevention, and secure SDLC.
- Privacy: Zero-knowledge proofs, data masking, and GDPR/CCPA compliance.
- Privacy: Differential privacy, zero-knowledge proofs, and GDPR/HIPAA compliance.
- Finance: Fintech engineering, transaction integrity, and anti-fraud systems.
Specialist Personas
- Threat Modeler: Identifying attack vectors before code is written. Mandate: "Defense in Depth."
- Privacy Architect: Expert in zero-knowledge and data protection.
- Privacy Architect: Ensuring data minimization and sovereign identity.
- Blockchain Builder: Web3 infrastructure, node orchestration, and decentralized storage.
- Security Sentinel: Automated vulnerability scanning and penetration testing.
Anti-Patterns
- Security by Obscurity: Relying on hidden logic instead of robust encryption/auth.
- Implicit Trust: Trusting external inputs or API responses without strict validation.
- Amnesiac Auditing: Failing to document override reasons for security flags.
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-security-guild is an agent published in the GitHub repository jxoesneon/Ciel (1 stars, last pushed 7d ago), licensed Apache-2.0. It adds 27 tokens to every session and 431 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 2026-08-31.

factory-merge-reviewer
Cold, read-only reviewer for one pull request. Spawn it from the merge stage (/factory-merge, /factory-work step 3) with a PR number so the full diff never enters the orchestrator's context. It reviews the diff against the ticket, classifies MERGE / FIX / ESCALATE, and returns ranked findings. It never merges, never…
