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 | $0.00045 | $0.00888 |
| Opus 5 | $0.00023 | $0.00444 |
| Sonnet 5 | $0.00009 | $0.00178 |
| Haiku 4.5 | $0.00005 | $0.00089 |
Grade A, and why
blueprint 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.

CIEL ADAPTATION: Blueprint — Construction Plan Generator
This skill turns a one-line objective into a step-by-step construction plan that any coding agent can execute cold. Unlike make-plan (which produces a simple linear task list), Blueprint adds adversarial review gates, dependency graphs with parallel step detection, an anti-pattern catalog, a plan mutation protocol, and self-contained per-step context briefs designed for multi-session and multi-agent use. Pure planning — no execution, zero runtime risk.
When to Use
- Breaking a large feature into multiple PRs with clear dependency order
- Planning a refactor or migration spanning multiple sessions
- Coordinating parallel workstreams across sub-agents
- Any task where context loss between sessions would cause rework
Do not use for tasks completable in a single PR, fewer than 3 tool calls, or when the user says "just do it."
5-Phase Pipeline
- Research — Pre-flight checks (git, gh auth, remote, default branch). Reads project structure, existing plans, and memory files for context.
- Design — Breaks objective into one-PR-sized steps (3–12 typical). Assigns dependency edges, parallel/serial ordering, model tier (strongest vs default), and rollback strategy per step.
- Draft — Writes self-contained Markdown plan to
plans/. Every step includes context brief, task list, verification commands, and exit criteria — a fresh agent can execute any step without reading prior steps. - Review — Delegates adversarial review to a strongest-model sub-agent against a checklist and anti-pattern catalog. Fixes all critical findings before finalizing.
- Register — Saves plan, updates memory index, presents step count and parallelism summary.
Key Features
- Cold-start execution: Every step has a self-contained context brief — no prior context needed.
- Adversarial review gate: Strongest-model sub-agent reviews every plan for completeness, dependency correctness, and anti-patterns.
- Branch/PR/CI workflow: Built into every step; degrades gracefully to direct mode when git/gh is absent.
- Parallel step detection: Dependency graph identifies steps with no shared files or output dependencies.
- Plan mutation protocol: Steps can be split, inserted, skipped, reordered, or abandoned with formal protocols and audit trail.
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.

blueprint is a skill published in the GitHub repository jxoesneon/Ciel (1 stars, last pushed 3d ago), licensed Apache-2.0. It adds 45 tokens to every session and 888 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 2026-09-03.
