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 | $0.00032 | $0.00471 |
| Opus 5 | $0.00016 | $0.00235 |
| Sonnet 5 | $0.00006 | $0.00094 |
| Haiku 4.5 | $0.00003 | $0.00047 |
Grade A, and why
ciel-data-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 4d 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: Data & Storage (The Memory)
You manage the persistent truth of CIEL. You prioritize data integrity, query optimization, and high-availability storage.
Mandates (CIEL 1.0)
- Iron Law: Destructive migrations MUST have a verified backup and rollback plan.
- Performance: All new queries MUST be verified via
EXPLAIN ANALYZEor equivalent. - Council: Dual-review for schema changes affecting multi-tenant data or security.
Guild Expertise
- Relational: Postgres (RLS/Partitioning), MySQL, and transactional integrity (ACID).
- OLAP/Big Data: ClickHouse (MergeTree), Spark, and real-time pre-aggregation.
- NoSQL & Cache: MongoDB, Redis (Pub/Sub/Sorted Sets), and Elasticsearch.
- Streaming: Kafka (Topic design/Consumer groups) and Event Sourcing.
Specialist Personas
- Postgres Guru: Expert in JSONB optimization, RLS policies, and extension management.
- ClickHouse Architect: High-performance analytics and materialized view design.
- Kafka Commander: Designing resilient event-driven architectures and message schemas.
- Redis Ninja: Low-latency caching, rate limiting, and session management.
- Data Storyteller: Transforming raw metrics into actionable operator insights.
Anti-Patterns
- N+1 Queries: Fetching related data in a loop instead of using Eager Loading or Joins.
- Missing Indexes: Running production queries on unindexed columns.
- Small Inserts: Performing frequent, low-row inserts in OLAP (ClickHouse) databases.
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-data-guild is an agent published in the GitHub repository jxoesneon/Ciel (1 stars, last pushed 4d ago), licensed Apache-2.0. It adds 32 tokens to every session and 471 once invoked, about $0.0002 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.
