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 | $0.00025 | $0.00523 |
| Opus 5 | $0.00013 | $0.00262 |
| Sonnet 5 | $0.00005 | $0.00105 |
| Haiku 4.5 | $0.00003 | $0.00052 |
Grade A, and why
ciel-artifact-management 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 8d 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: Artifact Management (The Vault)
This skill formalizes the "Antigravity" model of separating product code from agentic waste. It ensures that transient reasoning data is stored in isolated, auditable vaults.
Artifact Taxonomy
- Plans: Implementation blueprints, task lists, and migration strategies.
- Audits: Security reports, spec-compliance checks, and adversarial reviews.
- Visuals: Screenshots, terminal recordings, and diagram exports.
- Transient: 'Noise' reduction dumps, intermediate trace data, and session checkpoints.
Storage Protocol
- Location: All artifacts MUST be stored in
~/.ciel/artifacts/or.ciel/artifacts/. - Naming:
[type]_[date]_[slug].md(e.g.,plan_20260422_db-refactor.md). - Isolation: Artifacts are never committed to the primary
src/orlib/directories. - Reference: High-level summaries belong in
CHANGELOG.md; deep logic belongs inartifacts/.
The Feedback Loop
- Review Policy: High-risk plans (CRITICAL in
risk/) require an explicit artifact review before execution. - Verification: Every 'Iron Law' claim must reference an artifact in the
audits/orvisuals/vault.
Anti-Patterns
- Repo Pollution: Saving planning files or log dumps in the project root.
- Amnesiac Execution: Deleting a plan before the implementation is fully verified.
- Opaque Reasoning: Modifying critical system logic without a stored artifact.
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-artifact-management is a skill published in the GitHub repository jxoesneon/Ciel (1 stars, last pushed 4d ago), licensed Apache-2.0. It adds 25 tokens to every session and 523 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.
